本申請案係以日本專利申請案第2007-175220號為基礎，該案之內容以引用之方式併入本文中。The present application is based on Japanese Patent Application No. 2007-175220, the content of which is hereby incorporated by reference.
習知地，舉例而言，存在一種用於諸如具有滑動柱塞及收納柱塞之柱塞孔之泵的機器的密封總成。此密封總成係藉由交替堆疊由腈橡膠製成之軟性環及由氟樹脂製成之剛性環而製成，其具有V形截面且插在上部硬質密封環與下部硬質密封環之間(例如，專利文獻1)。Conventionally, for example, there is a seal assembly for a machine such as a pump having a sliding plunger and a plunger bore that receives the plunger. The sealing assembly is formed by alternately stacking a soft ring made of nitrile rubber and a rigid ring made of fluororesin, having a V-shaped cross section and interposed between the upper hard seal ring and the lower hard seal ring ( For example, Patent Document 1).
此外，存在另一習知密封總成，其包括：一擰至一柱塞孔之後端中的填料壓蓋螺母；一毗連該填料壓蓋螺母之填料壓蓋間隔件；一毗連該填料壓蓋間隔件之潤滑壓蓋；密封環之單一堆疊，該等密封環中之每一者的正面具有一凹陷形狀且背面具有一凸起形狀；一陰轉接環，其插在該潤滑壓蓋與該等密封環之間，凹陷正面對應於該等密封環之凸起背面的該陰轉接環毗連該等密封環；及一陽轉接環，其定位於該堆疊中之第一密封環前面，凸起背面對應於該 等密封環之凹陷正面的該陽轉接環毗連該等密封環(例如，專利文獻2)。In addition, there is another conventional sealing assembly comprising: a packing gland nut screwed into a rear end of a plunger hole; a packing gland spacer adjoining the packing gland nut; and a packing gland adjacent thereto a lubricating gland of the spacer; a single stack of sealing rings, each of the sealing rings having a concave shape on the front surface and a convex shape on the back surface; a female adapter ring inserted in the lubrication gland Between the seal rings, the female adapter ring corresponding to the convex back surface of the seal ring adjoins the seal rings; and a male adapter ring positioned in front of the first seal ring in the stack The raised back corresponds to the The male adapter ring on the front side of the recess of the seal ring abuts the seal rings (for example, Patent Document 2).
[專利文獻1]美國專利第5,577,737號[Patent Document 1] U.S. Patent No. 5,577,737
[專利文獻2]美國專利第4,572,519號[Patent Document 2] U.S. Patent No. 4,572,519
然而，專利文獻1中所描述之習知密封總成因具有藉由交替堆疊由腈橡膠製成之軟性環與由氟樹脂製成之剛性環組成之結構(具有V形截面且插在上部硬質密封環與下部硬質密封環之間)而可滑動地支撐柱塞孔中之柱塞。因此，當柱塞在高壓下往復滑動時，軟性環歸因於其柔軟性而過度彈性變形，且緊密接觸柱塞之能力增加。然而，當柱塞或桿之操作速度增加，或當柱塞孔中之內部壓力增加，或當柱塞受熱時，軟性環之柔軟性及強度快速劣化，且緊密接觸能力及密封能力降低，因此發生洩漏。However, the conventional sealing assembly described in Patent Document 1 has a structure consisting of a soft ring made of a nitrile rubber and a rigid ring made of a fluororesin alternately stacked (having a V-shaped cross section and being inserted in an upper hard seal) A plunger in the plunger bore is slidably supported between the ring and the lower rigid seal ring. Therefore, when the plunger reciprocates under high pressure, the soft ring is excessively elastically deformed due to its softness, and the ability to closely contact the plunger increases. However, when the operating speed of the plunger or the rod is increased, or when the internal pressure in the plunger hole is increased, or when the plunger is heated, the softness and strength of the soft ring are rapidly deteriorated, and the close contact ability and the sealing ability are lowered, A leak has occurred.
此外，根據專利文獻1中所描述之習知密封總成，當金屬柱塞滑動時，由腈橡膠製成之軟性環之耐磨性降低，軟性環被極度磨損且可能破裂，且與柱塞之緊密接觸位置因超出應力極限而損壞。因此，軟性環之機械壽命較短。因此，應頻繁地以另一軟性環替換該軟性環。維護檢查需要相當大的人工。Further, according to the conventional sealing assembly described in Patent Document 1, when the metal plunger slides, the abrasion resistance of the soft ring made of nitrile rubber is lowered, the soft ring is extremely worn and may be broken, and the plunger The close contact position is damaged by exceeding the stress limit. Therefore, the soft ring has a short mechanical life. Therefore, the soft ring should be replaced frequently with another soft ring. Maintenance inspections require considerable labor.
因此，當藉由增加軟性環對金屬柱塞之柔軟性以增加接觸力而增加密封能力時，軟性環耐磨性不足。相反，當增加軟性環之耐磨性時，軟性環之柔軟性被損壞，且對柱塞之密封能力降低。因此，習知地，獲得具有平衡的密封能力及耐磨性之高壓密封件非常困難。基本上，專利文獻1中所描述之習知密封總成係在約8000至12000PSI之正常 壓力下使用而不在100MPa下之高壓下使用。Therefore, when the sealing ability is increased by increasing the softness of the soft ring to the metal plunger to increase the contact force, the soft ring wear resistance is insufficient. On the contrary, when the wear resistance of the soft ring is increased, the softness of the soft ring is damaged, and the sealing ability to the plunger is lowered. Therefore, it is conventionally difficult to obtain a high-pressure seal having a balanced sealing ability and wear resistance. Basically, the conventional sealing assembly described in Patent Document 1 is normal at about 8,000 to 12,000 PSI. Use under pressure and not under high pressure at 100 MPa.
此外，根據專利文獻2中所描述之習知密封總成，具有大體呈V形截面之複數個單獨密封環係插在正面具有凹陷形狀的陰金屬轉接環與背面具有凸起形狀的陽金屬轉接環之間。因此，當柱塞在高壓下往復滑動時，轉接環轉接環執行陽金屬轉接環及陰金屬轉接環之剛性及潤滑壓蓋之潤滑能力。然而，類似於專利文獻1，密封環對柱塞之耐磨性未得到充分改良。此外，密封環柔軟性及可撓性不足且可能劣化並破裂。此外，密封環與柱塞之接觸點可能因超出應力極限而損壞。Further, according to the conventional sealing assembly described in Patent Document 2, a plurality of individual sealing rings having a substantially V-shaped cross section are inserted into a female metal adapter ring having a concave shape on the front side and a male metal having a convex shape on the back side. Between the adapter rings. Therefore, when the plunger reciprocates under high pressure, the adapter ring adapter performs the rigidity of the male metal adapter ring and the female metal adapter ring and the lubrication ability of the lubrication gland. However, similarly to Patent Document 1, the wear resistance of the seal ring to the plunger is not sufficiently improved. In addition, the seal ring is insufficient in flexibility and flexibility and may deteriorate and rupture. In addition, the point of contact of the seal ring with the plunger may be damaged by exceeding the stress limit.
在專利文獻2中所描述之習知密封總成中，當柱塞之運轉速度增加，柱塞孔之內部壓力增加，或柱塞之溫度增加時，亦發生密封環之耐磨性、可撓性、彈性可變形性及強度之降級。因此，密封總成之密封能力不足，可能發生洩漏，且機械壽命較短。應頻繁地以另一軟性環替換該軟性環。維護檢查需要相當大的人工。In the conventional sealing assembly described in Patent Document 2, when the operating speed of the plunger increases, the internal pressure of the plunger hole increases, or the temperature of the plunger increases, the wear resistance and flexibility of the sealing ring also occur. Degradation of sex, elastic deformability and strength. Therefore, the sealing assembly has insufficient sealing ability, leakage may occur, and the mechanical life is short. The soft ring should be replaced frequently with another soft ring. Maintenance inspections require considerable labor.
此外，如上所述，即使在專利文獻2中所描述之習知密封總成中，具有大體呈V形截面之複數個單獨密封環係插在正面具有凹陷形狀的陰金屬轉接環與背面具有凸起形狀的陽金屬轉接環之間。此外，擰至柱塞孔之末端中之填料壓蓋、緊壓填料壓蓋之填料壓蓋間隔件及毗連填料壓蓋間隔件之潤滑環係提供於柱塞孔中。因此，零件之數目大且密封總成之結構複雜。因此，製造並裝配密封總成並不容易，且需要相當大的人工。Further, as described above, even in the conventional sealing assembly described in Patent Document 2, a plurality of individual sealing rings having a substantially V-shaped cross section are inserted into the female metal adapter ring having a concave shape on the front side and the back surface. A convex shape between the male metal adapter rings. Further, a packing gland screwed into the end of the plunger hole, a packing gland spacer for pressing the packing gland, and a lubrication ring adjacent to the packing gland spacer are provided in the plunger hole. Therefore, the number of parts is large and the structure of the sealing assembly is complicated. Therefore, it is not easy to manufacture and assemble the sealing assembly, and considerable labor is required.
因此，本發明之一目標為提供一種高壓密封裝置，其藉由防止填充部材相對於滑桿或滑動活塞過度變形而具有良好跟隨能力、藉由以適當接觸力緊密接觸桿或活塞而在高壓下具有良好密封能力，及降級少的良好耐磨性，且發揮高強度且具有使維護檢查容易之長機械壽命，及高耐熱性，此外，其由少量零件組成且具有簡單結構以允許容易地製造及裝配。Accordingly, it is an object of the present invention to provide a high pressure sealing device which has good followability by preventing excessive deformation of the filling member relative to the slide bar or the sliding piston, and is under high pressure by close contact with the rod or piston with appropriate contact force.

本發明之此等及其他目標、特徵及優點將在參看隨附圖式閱讀以下詳細描述時變得顯而易見。The above and other objects, features and advantages of the present invention will become more apparent upon reading
將參看圖1至圖5解釋根據本發明之高壓密封裝置之第一實施例。A first embodiment of a high pressure sealing device according to the present invention will be explained with reference to Figs.
如圖1至圖5所示，根據第一實施例之密封裝置包括：一頂部轉接器1，其具有一在俯視時為大體呈環形之形狀且在頂部轉接器1之底壁處包括一具有一倒V形截面之填料收納凹部2；一底部轉接器3，其具有一在俯視時為大體呈環形之形狀且在底部轉接器3之頂壁處包括一具有一倒V形截面之填 料支撐壁4；複數個填充部材5，其各自具有一在俯視時為大體呈環形之形狀及倒V形截面，且插在頂部轉接器1與底部轉接器3之間；及複數個金屬承托環6，其各自具有一在俯視時為大體呈環形之形狀及倒V形截面，其包括一位於承托環6之底壁處之填料收納部分7，且與填充部材5交替重疊，其中該等填充部材係由硬質合成樹脂製成，且其中形成一允許變形間隙K以用於使填充部材5在填充部材5之頂壁5a或底壁5b及頂部轉接器1之底壁、承托環6之頂壁6a及底壁6b或底部轉接器3之頂壁3a中的至少兩個面對壁中歸因於軸向方向X中之壓縮力而壓縮變形。As shown in FIGS. 1 to 5, the sealing device according to the first embodiment comprises: a top adapter 1 having a substantially annular shape in plan view and including at the bottom wall of the top adapter 1 a packing receiving recess 2 having an inverted V-shaped cross section; a bottom adapter 3 having a generally annular shape in plan view and including an inverted V shape at the top wall of the bottom adapter 3 Fill in section a support wall 4; a plurality of filling members 5 each having a substantially annular shape and an inverted V-shaped cross section in a plan view, and interposed between the top adapter 1 and the bottom adapter 3; and a plurality of The metal support rings 6 each having a generally annular shape and an inverted V-shaped cross section in plan view, including a packing receiving portion 7 at the bottom wall of the support ring 6, and alternately overlapping the filling member 5. Wherein the filling members are made of a hard synthetic resin, and an allowable deformation gap K is formed therein for the filling member 5 at the top wall 5a or the bottom wall 5b of the filling member 5 and the bottom wall of the top adapter 1 At least two of the top wall 6a and the bottom wall 6b of the support ring 6 or the top wall 3a of the bottom adapter 3 are compressively deformed due to the compressive force in the axial direction X.
填充部材5係由聚醯胺樹脂、聚醚醚酮樹脂、聚乙烯樹脂、聚苯乙烯樹脂或聚氯乙烯樹脂中之任一者製成。較佳地，填充部材5係由聚醯胺樹脂或聚醚醚酮樹脂製成，且形成為硬質以用於耐受高壓。將填充部材5形成為硬質之原因係為了提供伴隨高壓下之變形而壓向柱塞或桿R之良好跟隨能力。因為填充部材5以適當對接力而密接該桿，所以填充部材5具有良好密封能力以穩妥地防止洩漏。此外，填充部材5係由相對較硬之合成樹脂製成，因此填充部材5可具有降級少的良好耐磨性，幾乎不產生磨損廢物且可發揮高強度及高耐熱性。The filling member 5 is made of any one of a polyamide resin, a polyetheretherketone resin, a polyethylene resin, a polystyrene resin, or a polyvinyl chloride resin. Preferably, the filling member 5 is made of a polyamide resin or a polyetheretherketone resin, and is formed to be hard for withstanding high pressure. The reason why the filling member 5 is formed to be hard is to provide a good followability to the plunger or the rod R with deformation under high pressure. Since the filling member 5 is in close contact with the rod with an appropriate abutting force, the filling member 5 has a good sealing ability to securely prevent leakage. Further, the filling member 5 is made of a relatively hard synthetic resin, and therefore the filling member 5 can have good wear resistance with less degradation, hardly generate abrasion waste, and can exhibit high strength and high heat resistance.
在圖2中，當解除壓縮力時，允許變形間隙K由一靠近填充部材5之厚度t的中心平分線M形成之接觸部分8及一非接 觸部分9組成，非接觸部分9之非接觸面積隨著非接觸部分9自接觸部分8延伸而增加。當裝設該密封裝置時，允許變形間隙K因拉緊裝配頂部轉接器1、填充部材5、承托環6及底部轉接器3之拉緊螺栓10而變窄。接著，在矯直填充部材5之整體形狀之後，將柱塞或桿R插入至填充部材5中，使得填充部材5由於軸向方向X中之壓縮力而變形。In Fig. 2, when the compressive force is released, the deformation gap K is allowed to be formed by a contact portion 8 and a non-contact formed by a center bisector M close to the thickness t of the filling member 5. The contact portion 9 is composed, and the non-contact area of the non-contact portion 9 increases as the non-contact portion 9 extends from the contact portion 8. When the sealing device is installed, the deformation gap K is allowed to be narrowed by tightening the tension bolts 10 of the top adapter 1, the filling member 5, the support ring 6, and the bottom adapter 3. Next, after straightening the entire shape of the filling member 5, the plunger or the rod R is inserted into the filling member 5 such that the filling member 5 is deformed by the compressive force in the axial direction X.
因為接觸部分8係形成於以中心平分線M為中心、半徑為r之弧形部8A上，所以填充部材5係夾在頂部轉接器1之底壁與承托環6之頂壁之間。因此，該密封裝置在高壓下具有良好的密封能力。Since the contact portion 8 is formed on the curved portion 8A having the radius r centered on the center bisector M, the filling member 5 is sandwiched between the bottom wall of the top adapter 1 and the top wall of the support ring 6. . Therefore, the sealing device has a good sealing ability under high pressure.
具體言之，根據第一實施例，在允許變形間隙K中，填充部材5之頂壁處之傾斜角θ1小於形成於頂部轉接器1之底壁上的填料收納凹部2之傾斜角θ2及形成於承托環6之底壁6b處的填料收納部分7之傾斜角θ2。此外，填充部材5之底壁5b處之傾斜角θ3大於承托環6之頂壁6a處之傾斜角θ4及底部轉接器3之頂壁處之傾斜角θ4。Specifically, according to the first embodiment, in the allowable deformation gap K, the inclination angle θ1 at the top wall of the filling member 5 is smaller than the inclination angle θ2 of the packing accommodation recess 2 formed on the bottom wall of the top adapter 1 and The inclination angle θ2 of the packing accommodating portion 7 formed at the bottom wall 6b of the receiving ring 6 is formed. Further, the inclination angle θ3 at the bottom wall 5b of the filling member 5 is larger than the inclination angle θ4 at the top wall 6a of the receiving ring 6 and the inclination angle θ4 at the top wall of the bottom adapter 3.
更具體言之，根據第一實施例，如圖1及圖2所示，傾斜角θ1及θ4中之每一者為115度。傾斜角θ2及θ3中之每一者為120度。然而，根據本發明，此等傾斜角並不限於之彼等角。More specifically, according to the first embodiment, as shown in FIGS. 1 and 2, each of the inclination angles θ1 and θ4 is 115 degrees. Each of the inclination angles θ2 and θ3 is 120 degrees. However, according to the present invention, such tilt angles are not limited to the same angle.
此外，非接觸部分9具有一大體呈三角形之截面且關於中心平分線M線對稱。因此，當安裝填充部材5時，允許變形間隙K因拉緊拉緊螺栓10而變窄。接著，在矯直填充部材5之後，將柱塞或桿R插入至填充部材5中。因此，軸 向方向X中之壓縮力使填充部材5變形以接近非接觸部分9。因此，防止柱塞或桿R超過應力極限或彈性極限之過度變形，且進行填充部材5之雙側平衡變形。因此，因為填充部材5收納分散之高壓，所以填充部材5以適當接觸力緊密接觸柱塞或桿R且具有良好密封能力。此外，在填充部材5之內部圓周上，填充部材5相對於柱塞或桿R之磨損減少，填充部材5之耐磨性增加，歸因於磨損的填充部材5之發熱得到調節，且填充部材5之壽命增加。Further, the non-contact portion 9 has a substantially triangular cross section and is line symmetrical with respect to the center bisector M. Therefore, when the filling member 5 is mounted, the deformation gap K is allowed to be narrowed by tightening the tension bolt 10. Next, after the filling of the filling member 5, the plunger or the rod R is inserted into the filling member 5. Therefore, the shaft The compressive force in the direction X deforms the filling member 5 to approach the non-contact portion 9. Therefore, the plunger or the rod R is prevented from exceeding excessive deformation of the stress limit or the elastic limit, and the double-sided balance deformation of the filling member 5 is performed. Therefore, since the filling member 5 accommodates the dispersed high pressure, the filling member 5 closely contacts the plunger or the rod R with an appropriate contact force and has a good sealing ability. Further, on the inner circumference of the filling member 5, the wear of the filling member 5 with respect to the plunger or the rod R is reduced, the wear resistance of the filling member 5 is increased, the heat generation due to the worn filling member 5 is adjusted, and the filling member is filled. The life of 5 is increased.
當然，根據第一實施例之填充部材5可以耐受小於100MPa之壓力，且可以耐受100MPa以上之壓力以具有良好密封能力。較佳地，填充部材5耐受超過280MPa之壓力且具有良好密封能力以穩妥地防止洩漏。Of course, the filling member 5 according to the first embodiment can withstand a pressure of less than 100 MPa, and can withstand a pressure of 100 MPa or more to have a good sealing ability. Preferably, the filling member 5 withstands a pressure exceeding 280 MPa and has a good sealing ability to securely prevent leakage.
一剖面積自高壓側至低壓側逐漸減小的具有一斜坡11a之唇狀部分11至少形成於柱塞或桿R所密接的填充部材5之內部側壁上。歸因於唇狀部分11，防止填充部材5過度變形，填充部材5對於在軸向方向X上往復滑動的柱塞或桿R具有良好跟隨能力，且以適當接觸力緊密接觸柱塞或桿R以具有良好密封能力。此外，減少與柱塞或桿R之磨損以改良耐磨性。A lip portion 11 having a slope 11a which is gradually reduced from a high pressure side to a low pressure side is formed at least on the inner side wall of the filling member 5 to which the plunger or the rod R is in close contact. Due to the lip portion 11, the filling member 5 is prevented from being excessively deformed, and the filling member 5 has a good followability with respect to the plunger or the rod R that reciprocally slides in the axial direction X, and closely contacts the plunger or the rod R with an appropriate contact force. To have a good sealing ability. In addition, wear with the plunger or rod R is reduced to improve wear resistance.
具體言之，斜坡11a相對於中心平分線M具有傾斜角α。在第一實施例中，傾斜角α為5度。對應於填充部材5之硬度等級、厚度、高度等等，改變斜坡11a之傾斜角α。因此，可適當地改變並調整填充部材5對柱塞或桿R之密封能力及耐磨性。Specifically, the slope 11a has an inclination angle α with respect to the center bisector M. In the first embodiment, the inclination angle α is 5 degrees. The inclination angle α of the slope 11a is changed corresponding to the hardness level, thickness, height, and the like of the filling member 5. Therefore, the sealing ability and wear resistance of the filling member 5 to the plunger or the rod R can be appropriately changed and adjusted.
此外，頂部轉接器1、承托環6或底部轉接器3中之任一者係由磷青銅(第二類或第三類)、不鏽鋼(SUS329J4L)、鋁青銅(第二類或第三類)、鎳銀(第二類或第三類)或鈹銅合金中之任一者製成。因此，頂部轉接器1、承托環6或底部轉接器3之機械壽命增加，且其耐熱特性、防鏽能力及耐化學性增加。In addition, either the top adapter 1, the support ring 6 or the bottom adapter 3 is made of phosphor bronze (second or third), stainless steel (SUS329J4L), aluminum bronze (second or first) Any of three types), nickel silver (second or third) or beryllium copper alloy. Therefore, the mechanical life of the top adapter 1, the support ring 6, or the bottom adapter 3 is increased, and its heat resistance, rust resistance, and chemical resistance are increased.
為了將密封裝置安裝至目標設備B(諸如用於處理並分割材料之高壓均質機或高壓泵)之填料收納凹部12中，首先，將頂部轉接器1及底部轉接器3配置在上方及下方。接著，將填充部材5及承托環6彼此交替重疊地放在頂部轉接器1與底部轉接器3之間。接著，蓋上一蓋F並拉緊複數個拉緊螺栓10以使允許變形間隙K變窄且矯直填充部材5之整體形狀。此時，選擇對應於目標設備B之正常內部壓力的填充部材5及承托環6之數目。In order to mount the sealing device to the packing receiving recess 12 of the target device B such as a high pressure homogenizer or a high pressure pump for processing and dividing the material, first, the top adapter 1 and the bottom adapter 3 are disposed above and Below. Next, the filling member 5 and the receiving ring 6 are placed between the top adapter 1 and the bottom adapter 3 alternately overlapping each other. Next, a cover F is covered and a plurality of tension bolts 10 are tightened to allow the deformation gap K to be narrowed and the overall shape of the filling member 5 to be straightened. At this time, the number of the filling member 5 and the receiving ring 6 corresponding to the normal internal pressure of the target device B is selected.
如圖1及圖2所示，當在拉緊拉緊螺栓10之前解除壓縮力時，允許變形間隙K係朝向高壓側P而形成於填充部材5之頂壁5a、底壁5b、頂部轉接器1之底壁、承托環6之頂壁6a及底壁6b以及底部轉接器3之頂壁中的兩個面對壁之間。As shown in FIGS. 1 and 2, when the compressive force is released before the tension bolt 10 is tightened, the deformation gap K is allowed to be formed on the top wall 5a, the bottom wall 5b, and the top of the filling member 5 toward the high pressure side P. The bottom wall of the device 1, the top wall 6a and the bottom wall 6b of the support ring 6, and the two of the top walls of the bottom adapter 3 face between the walls.
接著，將柱塞或桿R自蓋F之頂部插入至收納於填料收納凹部12中之密封總成中。接著，除拉緊螺栓10之拉緊力外，由柱塞或桿R之插入而在軸向方向X中產生的壓縮力使填充部材5在軸向方向X中變形。因此，如圖5所示，每一允許變形間隙K閉合。此時，填充部材5之容積因允許變形間隙K閉合而減小。因此，促使填充部材5在軸向方向、 垂直於軸向方向之徑向方向及圓周方向中平穩、快速且容易地變形，同時防止過度變形。因此，填充部材5以適當接觸力緊密接觸柱塞或桿R以具有良好密封能力並防止洩漏。此外，因為使填充部材5對在軸向方向X往復滑動的柱塞或桿R之跟隨能力增加，所以即使在高壓下，當操作目標設備B時，亦可防止超出應力極限及彈性極限之過度變形(參見圖2及圖4)。因此，柱塞或桿R往復且液體密封地於軸向方向X中在頂部轉接器1、填充部材5、承托環6及底部轉接器3內滑動。Next, the plunger or the rod R is inserted into the sealing assembly accommodated in the packing accommodation recess 12 from the top of the cover F. Next, in addition to the tensioning force of the tension bolt 10, the compressive force generated in the axial direction X by the insertion of the plunger or the rod R deforms the filling member 5 in the axial direction X. Therefore, as shown in FIG. 5, each of the allowable deformation gaps K is closed. At this time, the volume of the filling member 5 is reduced by allowing the deformation gap K to be closed. Therefore, the filling member 5 is urged in the axial direction, It deforms smoothly, quickly and easily in the radial direction and the circumferential direction perpendicular to the axial direction while preventing excessive deformation. Therefore, the filling member 5 closely contacts the plunger or the rod R with an appropriate contact force to have a good sealing ability and prevent leakage. Further, since the following ability of the filling member 5 to the plunger or the rod R that reciprocates in the axial direction X is increased, even when the target device B is operated under high pressure, the stress limit and the elastic limit are prevented from being excessive. Deformation (see Figure 2 and Figure 4). Thus, the plunger or rod R slides back and forth in the axial direction X in the axial direction X in the top adapter 1, the filling member 5, the support ring 6 and the bottom adapter 3.
此時，填充部材5之頂壁處之傾斜角θ1小於形成於頂部轉接器1之底壁上的填料收納凹部2之傾斜角θ2及形成於承托環6之底壁處的填料收納部分7之傾斜角θ2。此外，填充部材5之底壁處之傾斜角θ3大於承托環6之頂壁處之傾斜角θ4及底部轉接器3之頂壁處之傾斜角θ4。此外，形成於填充部材5之頂壁5a及底壁5b處之允許變形間隙K隨著該等壁自靠近中心平分線M的接觸部分8延伸而變寬。因此，當在軸向方向X中的拉緊螺栓10之壓縮力使允許變形間隙K閉合時，填充部材5緊密接觸頂部轉接器1之底壁、承托環6之頂壁及底壁以及底部轉接器3之頂壁。因為填充部材5歸因於提供允許變形間隙K而以其先前減小之容積進行緊密接觸，所以可防止超出應力極限及彈性極限之過度變形。At this time, the inclination angle θ1 at the top wall of the filling member 5 is smaller than the inclination angle θ2 of the packing accommodation recess 2 formed on the bottom wall of the top adapter 1 and the filler accommodating portion formed at the bottom wall of the support ring 6. The inclination angle of θ2 is 7. Further, the inclination angle θ3 at the bottom wall of the filling member 5 is larger than the inclination angle θ4 at the top wall of the receiving ring 6 and the inclination angle θ4 at the top wall of the bottom adapter 3. Further, the allowable deformation gap K formed at the top wall 5a and the bottom wall 5b of the filling member 5 is widened as the walls extend from the contact portion 8 near the center bisector M. Therefore, when the compressive force of the tension bolt 10 in the axial direction X causes the deformation gap K to be closed, the filling member 5 closely contacts the bottom wall of the top adapter 1, the top and bottom walls of the support ring 6, and The top wall of the bottom adapter 3. Since the filling member 5 is in close contact with its previously reduced volume due to the provision of the allowable deformation gap K, excessive deformation beyond the stress limit and the elastic limit can be prevented.
此時，當解除拉緊螺栓10之壓縮力時，形成於柱塞或桿R之近側及遠側處的填充部材5之非接觸部分9形成為具有 一大體呈三角形之截面且關於中心平分線M線對稱。因此，歸因於提供非接觸部分9，可防止填充部材5相對柱塞或桿R之過度變形。此外，相對於中心平分線M，同等地在左邊方向及右邊方向中促使壓力變形。因為填充部材5中之一些在軸向方向X中收納分散之高壓，所以填充部材5以適當接觸力緊密接觸柱塞或桿R。At this time, when the compressive force of the tension bolt 10 is released, the non-contact portion 9 of the filling member 5 formed at the proximal side and the distal side of the plunger or the rod R is formed to have A generally triangular cross section and symmetrical about the center bisector M. Therefore, due to the provision of the non-contact portion 9, excessive deformation of the filling member 5 with respect to the plunger or the rod R can be prevented. Further, with respect to the center bisector M, the pressure deformation is promoted equally in the left direction and the right direction. Since some of the filling members 5 accommodate the dispersed high pressure in the axial direction X, the filling member 5 closely contacts the plunger or the rod R with an appropriate contact force.
此外，因為允許變形間隙K具有一大體呈三角形之截面且關於中心平分線M線對稱，所以以高精確度無偏差地進行填充部材5相對於底部轉接器3、承托環6及頂部轉接器1之裝配。Further, since the deformation gap K is allowed to have a substantially triangular cross section and is line-symmetric with respect to the center bisector M, the filling member 5 is rotated with respect to the bottom adapter 3, the support ring 6 and the top with high precision without deviation. Assembly of the connector 1.
此外，填充部材5係由相對較硬之合成樹脂(即，聚醯胺樹脂、聚醚醚酮樹脂、聚乙烯樹脂、聚苯乙烯樹脂或聚氯乙烯樹脂中之任一者)製成。此外，具有相對於中心平分線M具有諸如5度之傾斜角的斜坡11a之唇狀部分11(其用於使填充部材5之剖面積自高壓側至低壓側減小)至少形成於柱塞或桿R側的填充部材5之側壁上，使得填充部材5之容積減小。因此，促使填充部材5變形，同時防止超出應力極限及彈性極限之過度變形，且填充部材5對往復滑動之柱塞或桿R之跟隨能力良好。因為填充部材5以適當接觸力緊密接觸，所以獲得良好密封能力且穩妥地防止洩漏。此外，填充部材5相對於柱塞或桿R之磨損減小，填充部材5耐磨性增加。因此，填充部材5具有降級少的良好耐磨性且幾乎不產生磨損廢物。此外，因為藉由與由磷青銅、不鏽鋼、鋁青銅、鎳銀或鈹銅合金中之任一者製成之承托環 6交替重疊來保護填充部材5，所以填充部材5即使在高壓及高溫下亦保持高強度，且填充部材5之機械壽命增加。因此，用於以新部材替換填充部材5或清除磨損廢物之人工減少，維護檢查變得容易，填充部材5具有良好耐熱性，且因此，密封裝置發揮高強度且具有使維護檢查容易之長機械壽命，及高耐熱性，此外，該裝置由少量零件組成且具有簡單結構以允許容易地製造及裝配。Further, the filling member 5 is made of a relatively hard synthetic resin (i.e., any of a polyamide resin, a polyether ether ketone resin, a polyethylene resin, a polystyrene resin, or a polyvinyl chloride resin). Further, the lip portion 11 having the slope 11a having an inclination angle of, for example, 5 degrees with respect to the center bisector M (which serves to reduce the sectional area of the filling member 5 from the high pressure side to the low pressure side) is formed at least on the plunger or On the side wall of the filling member 5 on the side of the rod R, the volume of the filling member 5 is reduced. Therefore, the filling member 5 is caused to be deformed while preventing excessive deformation exceeding the stress limit and the elastic limit, and the filling member 5 has a good ability to follow the reciprocating sliding plunger or the rod R. Since the filling member 5 is in close contact with an appropriate contact force, a good sealing ability is obtained and leakage is securely prevented. Further, the wear of the filling member 5 with respect to the plunger or the rod R is reduced, and the wear resistance of the filling member 5 is increased. Therefore, the filling member 5 has a good wear resistance with less degradation and hardly generates abrasion waste. In addition, because of the support ring made of any one of phosphor bronze, stainless steel, aluminum bronze, nickel silver or beryllium copper alloy Since the filling member 5 is alternately overlapped, the filling member 5 maintains high strength even under high pressure and high temperature, and the mechanical life of the filling member 5 increases. Therefore, the manual reduction for replacing the filling member 5 with a new member or removing the abrasion waste becomes easy to perform maintenance inspection, the filling member 5 has good heat resistance, and therefore, the sealing device exhibits high strength and has a long mechanical mechanism for making maintenance inspection easy. Lifetime, and high heat resistance, in addition, the device consists of a small number of parts and has a simple structure to allow easy manufacture and assembly.
此外，因為頂部轉接器1、底部轉接器3及承托環6係由磷青銅、不鏽鋼、鋁青銅、鎳銀或鈹銅合金中之任一者製成，所以頂部轉接器1、底部轉接器3及承托環6對由硬金屬製成之柱塞或桿R的耐磨性良好且幾乎無降級，且該密封裝置發揮高強度且具有長機械壽命，且具有良好耐熱性、良好防鏽能力及良好耐化學性。In addition, since the top adapter 1, the bottom adapter 3 and the support ring 6 are made of any one of phosphor bronze, stainless steel, aluminum bronze, nickel silver or beryllium copper, the top adapter 1 The bottom adapter 3 and the support ring 6 have good wear resistance and almost no degradation to the plunger or rod R made of hard metal, and the sealing device exhibits high strength and long mechanical life, and has good heat resistance. Good rust resistance and good chemical resistance.
因此，當然，在根據第一實施例之填充部材5中，在小於100MPa之壓力下且在100MPa以上之壓力下、較佳在超過280MPa之壓力下，可防止超出應力極限及彈性極限之過度變形。填充部材5具有對柱塞或桿R之良好跟隨能力且以適當接觸力緊密接觸柱塞或桿R。因此，填充部材5具有良好密封能力且可穩妥地防止洩漏。此外，填充部材5具有降級少的良好耐磨性且發揮高強度。因此，填充部材5之機械壽命在連續運轉時大於幾百小時，且填充部材5之耐熱性高於120℃。因此，獲得在高壓下具有良好密封能力且具有良好耐磨性且能夠長時間運轉的高壓密封部材。因此，填充部材5可用於對於目標設備B之滑桿、活塞或柱 塞的密封裝置，目標設備B之一實例為用於藉由在高壓下分散、乳化或壓碎包括於懸浮液體中之材料來處理並分割材料的高壓均質機，或其另一實例為高壓泵。填充部材5之應用非常廣。Therefore, of course, in the filling member 5 according to the first embodiment, excessive deformation beyond the stress limit and the elastic limit can be prevented under a pressure of less than 100 MPa and a pressure of 100 MPa or more, preferably more than 280 MPa. . The filling member 5 has a good followability to the plunger or rod R and closely contacts the plunger or rod R with a suitable contact force. Therefore, the filling member 5 has a good sealing ability and can securely prevent leakage. Further, the filling member 5 has a good wear resistance with less degradation and exerts high strength. Therefore, the mechanical life of the filling member 5 is greater than several hundred hours in continuous operation, and the heat resistance of the filling member 5 is higher than 120 °C. Therefore, a high-pressure sealing member which has a good sealing ability under high pressure and which has good wear resistance and can be operated for a long time is obtained. Therefore, the filling member 5 can be used for the slide bar, piston or column of the target device B. One example of the sealing device of the plug, the target device B is a high pressure homogenizer for treating and dividing the material by dispersing, emulsifying or crushing the material contained in the suspended liquid under high pressure, or another example thereof is a high pressure pump . The application of the filling member 5 is very extensive.
將參看圖6至圖9解釋根據本發明之高壓密封裝置之第二實施例。A second embodiment of the high pressure sealing device according to the present invention will be explained with reference to Figs.
在第二實施例中，允許變形間隙K係形成於填充部材5之底壁5b處。在第一實施例中，當解除壓縮力時，允許變形間隙K係形成於填充部材5之頂壁5a及底壁5b處。在第二實施例中，形成於填充部材5之頂壁5a上之傾斜角θ1與形成於頂部轉接器1之底壁上的填料收納凹部2之傾斜角θ'2及形成於承托環6之底壁6b上的填料收納部分7之傾斜角θ'2大體上相同。此外，形成於填充部材5之底壁5b上之傾斜角θ3大於承托環6之頂壁6a之傾斜角θ4及底部轉接器3之頂壁之傾斜角θ4。形成於填充部材5之底壁5b處之允許變形間隙K隨著底壁5b自靠近中心平分線M的接觸部分8延伸而變寬。In the second embodiment, the deformation gap K is allowed to be formed at the bottom wall 5b of the filling member 5. In the first embodiment, when the compressive force is released, the deformation gap K is allowed to be formed at the top wall 5a and the bottom wall 5b of the filling member 5. In the second embodiment, the inclination angle θ1 formed on the top wall 5a of the filling member 5 and the inclination angle θ'2 of the packing accommodation recess 2 formed on the bottom wall of the top adapter 1 are formed on the support ring. The inclination angle θ'2 of the packing receiving portion 7 on the bottom wall 6b of 6 is substantially the same. Further, the inclination angle θ3 formed on the bottom wall 5b of the filling member 5 is larger than the inclination angle θ4 of the top wall 6a of the receiving ring 6 and the inclination angle θ4 of the top wall of the bottom adapter 3. The allowable deformation gap K formed at the bottom wall 5b of the filling member 5 is widened as the bottom wall 5b extends from the contact portion 8 near the center bisector M.
具體言之，傾斜角θ1、θ3及傾斜角θ'2為120度，且傾斜角θ4為115度。然而，根據本發明，此等傾斜角並不限於彼等角。Specifically, the inclination angles θ1, θ3 and the inclination angle θ'2 are 120 degrees, and the inclination angle θ4 is 115 degrees. However, according to the present invention, such inclination angles are not limited to the same angle.
此外，根據第二實施例，當安裝在目標設備B上時的軸向方向X中之壓縮力小於第一實施例之壓縮力時，允許變形間隙K閉合，使得填充部材5變形且緊密接觸承托環6及 底部轉接器3。此外，因為填充部材5係由金屬承托環6支撐，所以即使在高壓下，亦可防止填充部材5超出應力極限及彈性極限之過度變形，且促使填充部材5之變形。因此，填充部材5對柱塞或桿R之跟隨能力變得良好，且填充部材5以適當接觸力緊密接觸桿R或其類似物。因此，填充部材5發揮良好密封能力。因此，柱塞或桿R平滑且穩妥地滑動。此外，因為承托環6係由磷青銅、不鏽鋼、鋁青銅、鎳銀或鈹銅合金中之任一者製成，所以填充部材5對金屬柱塞或桿R之耐磨性增加，且歸因於磨損之發熱受到調節。Further, according to the second embodiment, when the compressive force in the axial direction X when mounted on the target device B is smaller than the compressive force of the first embodiment, the deformation gap K is allowed to be closed, so that the filling member 5 is deformed and closely contacted Support ring 6 and Bottom adapter 3. Further, since the filling member 5 is supported by the metal receiving ring 6, even under high pressure, the filling member 5 can be prevented from being excessively deformed beyond the stress limit and the elastic limit, and the deformation of the filling member 5 is promoted. Therefore, the following ability of the filling member 5 to the plunger or the rod R becomes good, and the filling member 5 closely contacts the rod R or the like with an appropriate contact force. Therefore, the filling member 5 exerts a good sealing ability. Therefore, the plunger or the rod R slides smoothly and steadily. In addition, since the support ring 6 is made of any one of phosphor bronze, stainless steel, aluminum bronze, nickel silver or beryllium copper alloy, the wear resistance of the filling member 5 to the metal plunger or the rod R is increased, and The heat due to wear is regulated.
圖10至圖13展示根據本發明之密封裝置之第三實施例。Figures 10 through 13 show a third embodiment of a sealing device in accordance with the present invention.
在第三實施例中，不同於第一實施例，允許變形間隙K係形成於填充部材5之頂壁5a上。即，在第三實施例中，形成於填充部材5之頂壁5a上之傾斜角θ1小於形成於頂部轉接器1之底壁上的填料收納凹部2之傾斜角θ2及形成於承托環6之底壁6b上的填料收納部分7之傾斜角θ2。此外，形成於填充部材5之底壁5b上之傾斜角θ3與承托環6之頂壁6a之傾斜角θ4及底部轉接器3之頂壁之傾斜角θ4大體上相同。形成於填充部材5之頂壁5a處之允許變形間隙K隨著頂壁5a自靠近中心平分線M的接觸部分8延伸而變寬。In the third embodiment, unlike the first embodiment, the deformation gap K is allowed to be formed on the top wall 5a of the filling member 5. That is, in the third embodiment, the inclination angle θ1 formed on the top wall 5a of the filling member 5 is smaller than the inclination angle θ2 of the packing accommodation recess 2 formed on the bottom wall of the top adapter 1, and is formed on the support ring. The inclination angle θ2 of the packing accommodating portion 7 on the bottom wall 6b of 6. Further, the inclination angle θ3 formed on the bottom wall 5b of the filling member 5 is substantially the same as the inclination angle θ4 of the top wall 6a of the receiving ring 6 and the inclination angle θ4 of the top wall of the bottom adapter 3. The allowable deformation gap K formed at the top wall 5a of the filling member 5 is widened as the top wall 5a extends from the contact portion 8 near the center bisector M.
根據第三實施例，由於拉緊螺栓10在軸向方向X中之壓縮力小於第一實施例之壓縮力，故允許變形間隙K閉合，且填充部材5之頂壁5a緊密接觸形成於頂部轉接器1之底壁 及承托環6之底壁6b上之填料收納凹部2。因為填充部材5係由由磷青銅、不鏽鋼、鋁青銅、鎳銀或鈹銅合金中之任一者製成之承托環6支撐，所以促使填充部材5變形，同時防止甚至在高壓下的超出應力極限及彈性極限之過度變形，且填充部材5對往復滑動之柱塞或桿R之跟隨能力良好。因為填充部材5以適當接觸力緊密接觸，所以獲得良好密封能力。因此，柱塞或桿R平滑且穩妥地滑動。此外，因為承托環6係由磷青銅、不鏽鋼、鋁青銅、鎳銀或鈹銅合金中之任一者製成，所以填充部材5對金屬柱塞或桿R之耐磨性增加，且歸因於磨損之發熱受到調節。According to the third embodiment, since the compressive force of the tension bolt 10 in the axial direction X is smaller than that of the first embodiment, the deformation gap K is allowed to be closed, and the top wall 5a of the filling member 5 is in close contact with the top turn. Bottom wall of connector 1 And a packing accommodation recess 2 on the bottom wall 6b of the support ring 6. Since the filling member 5 is supported by the support ring 6 made of any one of phosphor bronze, stainless steel, aluminum bronze, nickel silver or beryllium copper alloy, the filling member 5 is caused to be deformed while preventing the excess even under high pressure. Excessive deformation of the stress limit and the elastic limit, and the ability of the filling member 5 to follow the reciprocating sliding plunger or rod R is good. Since the filling member 5 is in close contact with an appropriate contact force, a good sealing ability is obtained. Therefore, the plunger or the rod R slides smoothly and steadily. In addition, since the support ring 6 is made of any one of phosphor bronze, stainless steel, aluminum bronze, nickel silver or beryllium copper alloy, the wear resistance of the filling member 5 to the metal plunger or the rod R is increased, and The heat due to wear is regulated.
