Abstract

There is demand for a valve having a simple and compact structure with a low parts count and capable of switching between the opening and closing of a flow passage. This problem is solved by the valve comprising: a pipe body that has a first flow passage in the interior thereof; a rod part that is fitted into the first flow passage and that has a second flow passage in the interior thereof; and a seal member that is disposed to the inner circumferential surface of the first flow passage. The seal member divides the first flow passage of the pipe body into a first region and a second region. The first region and the second region have no fluid communication therebetween. The rod part can move between a first state in which the communication of the fluid between the second flow passage and the first flow passage is stopped and a second state in which the rod part is in communication with the second region so as to promote the communication of the fluid between the second flow passage and the first flow passage.

Description

バルブvalve

　本発明は、バルブに関する。 The present invention relates to a valve.

　バルブでは、従来から、並進動作または回転動作により、流路を閉鎖する閉鎖状態と流路を開放する開放状態とを切り替える機構を有するものが存在する。たとえば、特許文献１に開示されるように、このようなバルブでは、たとえば、カムフォロワーがカム溝を移動することにより、バルブの閉鎖状態と開放状態との間の切り替えが喚起される機構が採用されることが多い。 Conventionally, there are valves that have a mechanism for switching between a closed state, which closes the flow path, and an open state, which opens the flow path, by translational or rotational motion. For example, as disclosed in Patent Document 1, such valves often employ a mechanism in which a cam follower moves along a cam groove to trigger switching between the closed and open states of the valve.

特許第６５０３４６５号公報Japanese Patent No. 6503465

　このような機構では、流路を閉鎖する部材が閉鎖位置と開放位置とを移動するため、所定のストロークが必要になる。所定のストロークを確保するためには、バルブの構造が大きくなる問題がある。 In such a mechanism, a certain stroke is required because the member that closes the flow path moves between a closed position and an open position. In order to ensure the certain stroke, the valve structure must be large.

　また、カムフォロワーとカム溝によりバルブの閉鎖状態と開放状態との間の切り替えが喚起される機構では、カム溝とカムフォロワーの配置をするために、部材の構成が複雑になる。また、それにより、流路のシール性を確保することが困難となる問題がある。 Furthermore, in a mechanism in which a cam follower and a cam groove are used to switch the valve between the closed and open states, the arrangement of the cam groove and cam follower makes the structure of the components complex. This also creates the problem of making it difficult to ensure the sealing of the flow path.

　部品点数が少なく簡易でコンパクトな構造で流路の開放と流路の閉鎖との切り替えが可能なバルブが求められている。 There is a demand for a valve that has a small number of parts, a simple and compact structure, and can switch between opening and closing the flow path.

　管路端部を有する管体であって、円筒形の内周面で画定され、流体の上流または下流のいずれか一方である第１流路を内部に有し、前記第１流路は前記管路端部において開口端を形成する管体と、円筒形状を外周面とする形状の棒体部であって、前記管体の前記開口端から前記第１流路内に挿嵌され、前記流体の前記上流または前記下流の他方である第２流路を内部に有して前記外周面上に前記第２流路の流路開口を備える棒体部と、前記第１流路の前記内周面上には前記棒体部の前記外周面に密着し前記内周面の一周回で無端となるように配置されるシール部材と、を備え、前記シール部材は、前記管体の前記管路端部の第１位置と前記第１位置よりも前記管体の前記管路端部から遠い第２位置とを通過するように配置され、前記管体の前記第１流路を前記第１流路の軸方向に沿って前記管路端部の側の第１領域と前記第１領域よりも前記管路端部から遠い第２領域とに分割し、前記第１領域と前記第２領域との間では流体的な連通が絶たれ、前記棒体部は、前記棒体部の前記流路開口が前記第１領域に連通して前記第２流路と前記第１流路との前記流体の連通を閉止する第１状態と、前記棒体部の前記流路開口が前記第２領域に連通して前記第２流路と前記第１流路との間の前記流体の連通を喚起する第２状態と、の間の移動が可能であるバルブにより解決する。 A pipe body having a pipeline end, the pipe body having a first flow path therein, the first flow path being defined by a cylindrical inner peripheral surface and being either the upstream or downstream side of a fluid, the first flow path forming an open end at the pipeline end, a rod body portion having a cylindrical outer peripheral surface, the rod body portion being inserted into the first flow path from the open end of the pipe body, the rod body portion having a second flow path therein, the second flow path being the other of the upstream or downstream side of the fluid, and a flow path opening of the second flow path on the outer peripheral surface, and a sealing member disposed on the inner peripheral surface of the first flow path so as to be in close contact with the outer peripheral surface of the rod body portion and to be endless in one revolution of the inner peripheral surface, the sealing member being disposed at a first position of the pipeline end of the pipe body. and a second position farther from the end of the pipe of the pipe than the first position, the first flow path of the pipe is divided along the axial direction of the first flow path into a first region on the side of the end of the pipe and a second region farther from the end of the pipe than the first region, fluid communication is cut off between the first region and the second region, and the rod portion is movable between a first state in which the flow path opening of the rod portion communicates with the first region to close the fluid communication between the second flow path and the first flow path, and a second state in which the flow path opening of the rod portion communicates with the second region to stimulate the fluid communication between the second flow path and the first flow path.

　本発明により、部品点数が少なく簡易でコンパクトな構造で流路の開放と流路の閉鎖との切り替えが可能となる。 The present invention makes it possible to switch between opening and closing the flow path with a simple, compact structure that requires a small number of parts.

A valve 1 according to a first embodiment of the present invention will be described with reference to Figures 1 to 4B. Figure 1 is a perspective view of the valve 1 according to the first embodiment of the present invention in an assembled state (left side) and in a disassembled state (right side). Figure 2 shows a development of the inner peripheral surface of the tube of the valve 1 according to the first embodiment of the present invention. Figure 3 shows an enlarged cross-sectional view of a seal member portion of the tube of the valve 1 according to the first embodiment of the present invention. Figure 4A is a cross-sectional view of the valve 1 according to the first embodiment of the present invention, showing the valve 1 in an open state. Figure 4B is a cross-sectional view of the valve 1 according to the first embodiment of the present invention, showing the valve 1 in a closed state.

　バルブ１は流体が流れる任意の流路内に配置される。バルブ１は、棒体部１２と管体１３とを備える。棒体部１２は第２流路１２３を内部に有し、管体１３は第１流路１３３を内部に有する。第１流路１３３はバルブ１が配置される任意の流路の上流と下流の一方に接続され、第２流路１２３はバルブ１が配置される任意の流路の上流と下流の他方に接続される。バルブ１の開放状態において第１流路１３３と第２流路１２３とが流体的に連通し、バルブ１の閉鎖状態において第１流路１３３と第２流路１２３との流体的な連通が遮断される。以下、ここでは、第１流路１３３が上流側に接続され、第２流路１２３が下流側に接続されている例で説明する。ただし、この逆であってもよい。 The valve 1 is disposed in any flow path through which a fluid flows. The valve 1 includes a rod portion 12 and a tube 13. The rod portion 12 has a second flow path 123 therein, and the tube 13 has a first flow path 133 therein. The first flow path 133 is connected to one of the upstream and downstream sides of any flow path in which the valve 1 is disposed, and the second flow path 123 is connected to the other upstream and downstream side of any flow path in which the valve 1 is disposed. When the valve 1 is in an open state, the first flow path 133 and the second flow path 123 are fluidly connected, and when the valve 1 is in a closed state, the fluidic connection between the first flow path 133 and the second flow path 123 is cut off. Hereinafter, an example will be described in which the first flow path 133 is connected to the upstream side, and the second flow path 123 is connected to the downstream side. However, this may be reversed.

　棒体部１２は、一端１２１と他端１２２とを有し、円筒形状を外周面とする形状を有する。棒体部１２は、棒体部１２の円筒形の軸上に沿って、棒体部１２の一端１２１から他端１２２へと延在する流路である第２流路１２３を有している。第２流路１２３はたとえば棒体部１２の一端１２１において開口を形成する。棒体部１２の第２流路１２３の他端１２２側は他端１２２に至る前に、第２流路１２３から棒体部１２の円筒形の表面に向けて第２流路１２３の延在する方向と垂直方向に延在する流路を形成し、棒体部１２の円筒表面上の開口としての流路開口１２４を形成する。 The rod portion 12 has one end 121 and the other end 122, and has a cylindrical shape as its outer circumferential surface. The rod portion 12 has a second flow path 123, which is a flow path that extends from one end 121 to the other end 122 of the rod portion 12 along the cylindrical axis of the rod portion 12. The second flow path 123 forms an opening, for example, at one end 121 of the rod portion 12. Before reaching the other end 122, the other end 122 side of the second flow path 123 of the rod portion 12 forms a flow path that extends from the second flow path 123 toward the cylindrical surface of the rod portion 12 in a direction perpendicular to the extension direction of the second flow path 123, and forms a flow path opening 124 as an opening on the cylindrical surface of the rod portion 12.

　管体１３は、開口端を形成する管路端部１３１を有している。第１流路１３３は円筒形の内周面１３２で画定される。棒体部１２の他端１２２は、管体１３の開口端から管体１３の第１流路１３３の内部に挿嵌される。棒体部１２は管体１３の第１流路１３３内で、棒体部１２の外周面に沿っての回転が可能なように第１流路１３３内に留まるように保持される。 The tube 13 has a pipe end 131 that forms an open end. The first flow path 133 is defined by a cylindrical inner circumferential surface 132. The other end 122 of the rod portion 12 is inserted into the inside of the first flow path 133 of the tube 13 from the open end of the tube 13. The rod portion 12 is held so that it remains within the first flow path 133 of the tube 13 and can rotate along the outer circumferential surface of the rod portion 12.

　管体１３の第１流路１３３の内周面１３２上にはシール部材１３４を備える。管体１３のシール部材１３４は、棒体部１２が第１流路１３３内に挿入された状態で、棒体部１２の外周面に密着する。シール部材１３４は、内周面１３２の一周回で無端となるような両端の無い環状形状を有している。 A seal member 134 is provided on the inner circumferential surface 132 of the first flow passage 133 of the tube body 13. The seal member 134 of the tube body 13 adheres closely to the outer circumferential surface of the rod portion 12 when the rod portion 12 is inserted into the first flow passage 133. The seal member 134 has an annular shape without both ends, so that one revolution around the inner circumferential surface 132 is endless.

　図２は、第１流路１３３の内周面１３２を展開した図である。この図でＹ点はＸ点に対して、第１流路１３３の中心軸に対して１８０度の位置関係にあり、図２の左端のＸ点と図２の右端のＸ点は同一点であって、図２の左端のＸ点と右端のＸ点との間が第１流路１３３の中心軸に対して３６０度の位置関係にある。 Figure 2 is a diagram showing the inner circumferential surface 132 of the first flow path 133 in a developed state. In this figure, point Y is at a positional relationship of 180 degrees with respect to point X and the central axis of the first flow path 133, point X at the left end of Figure 2 and point X at the right end of Figure 2 are the same point, and point X at the left end of Figure 2 and point X at the right end of Figure 2 are at a positional relationship of 360 degrees with respect to the central axis of the first flow path 133.

　シール部材１３４は、図２に示すように、第１流路１３３の内周面１３２において、第１位置と第２の位置とを通過するように配置される。第２位置は第１位置よりも管体１３の管路端部１３１から遠い位置である。たとえば、第１位置は管路端部１３１から距離ｄ１であるとして、第２位置は管路端部１３１から距離ｄ２（ｄ１＜ｄ２）である。すなわち、第１流路１３３において、第１流路１３３の管路断面の中心軸周りの中心角の異なる少なくとも２点において、第１流路１３３の延在する方向で管路端部１３１から異なる距離となる２点が画定され、シール部材１３４は、この少なくとも２点を経由するように配置されればよい。 As shown in Fig. 2, the seal member 134 is disposed on the inner peripheral surface 132 of the first flow passage 133 so as to pass through a first position and a second position. The second position is a position farther from the pipe end 131 of the pipe body 13 than the first position. For example, the first position is a distance d1 from the pipe end 131, and the second position is a distance d2 ( d1 < d2 ) from the pipe end 131. That is, in the first flow passage 133, at least two points having different central angles around the central axis of the pipe cross section of the first flow passage 133 are defined as two points at different distances from the pipe end 131 in the extending direction of the first flow passage 133, and the seal member 134 may be disposed so as to pass through at least these two points.

　シール部材１３４は、管体１３の第１流路１３３を、第１流路１３３の軸方向に沿って管路端部の側の第１領域１３３ａと第１領域よりも管路端部１３１から遠い第２領域１３３ｂとに分割する。管体１３の第１領域１３３ａの管路端部１３１の開口側は管路端部側シール部材１３１ａが全周に亘って配置される。管路端部側シール部材１３１ａは管体１３側ではなく棒体部１２側に配置してもよい。 The sealing member 134 divides the first flow path 133 of the tube body 13 into a first region 133a on the side of the pipe end and a second region 133b that is farther from the pipe end 131 than the first region along the axial direction of the first flow path 133. A pipe end side sealing member 131a is arranged around the entire circumference of the opening side of the pipe end 131 of the first region 133a of the tube body 13. The pipe end side sealing member 131a may be arranged on the rod portion 12 side instead of the tube body 13 side.

　すなわち、第１領域１３３ａは、シール部材１３４と、管路端部側シール部材１３１ａと、管路端部１３１側の管体１３の内面と、棒体部１２の外表面とで画定される領域である。一方、第２領域１３３ｂは、シール部材１３４と、管路端部１３１と反対側の管体１３の内面と、棒体部１２の外表面とで画定される領域である。 In other words, the first region 133a is an area defined by the seal member 134, the pipe end side seal member 131a, the inner surface of the pipe body 13 on the pipe end 131 side, and the outer surface of the rod body portion 12. On the other hand, the second region 133b is an area defined by the seal member 134, the inner surface of the pipe body 13 opposite the pipe end 131, and the outer surface of the rod body portion 12.

　シール部材１３４は棒体部１２の外周面に密着しているので、第１流路１３３の第１領域１３３ａと第１流路１３３の第２領域１３３ｂとの間では、流体の連通が絶たれている。棒体部１２は、棒体部１２の流路開口１２４が第１領域１３３ａに連通する第１状態（図４Ｂ）と、棒体部１２の流路開口１２４が第２領域１３３ｂに連通する第２状態（図４Ａ）と、の間の移動が可能である。 The seal member 134 is in close contact with the outer circumferential surface of the rod portion 12, so that fluid communication is cut off between the first region 133a of the first flow path 133 and the second region 133b of the first flow path 133. The rod portion 12 can move between a first state (FIG. 4B) in which the flow path opening 124 of the rod portion 12 communicates with the first region 133a, and a second state (FIG. 4A) in which the flow path opening 124 of the rod portion 12 communicates with the second region 133b.

　バルブ１は、第２状態（図４Ａ）において、第２流路１２３と第１流路１３３とが流体的に連通し、バルブ１の開放状態となる。この状態では、図４Ａの矢印のように、第２流路１２３と第１流路１３３との間に流体の流れを喚起する。一方、バルブ１は、第１状態（図４Ｂ）において、第２流路１２３と第１流路１３３との流体的な連通が遮断され、バルブ１の閉鎖状態となる。この状態では、図４Ａの矢印のような第２流路１２３と第１流路１３３との流体の流れは生じない。棒体部１２は、棒体部１２の円筒形状の外周表面に沿っての回転が可能なように管体１３の第１流路１３３内に挿嵌されているので、その回転によって第１状態と第２状態との間の移動が喚起される。 In the second state (FIG. 4A), the second flow path 123 and the first flow path 133 are fluidly connected, and the valve 1 is in an open state. In this state, as shown by the arrows in FIG. 4A, a fluid flow is induced between the second flow path 123 and the first flow path 133. On the other hand, in the first state (FIG. 4B), the valve 1 is in a closed state, and the fluid communication between the second flow path 123 and the first flow path 133 is cut off. In this state, no fluid flow occurs between the second flow path 123 and the first flow path 133, as shown by the arrows in FIG. 4A. The rod portion 12 is inserted into the first flow path 133 of the tube 13 so as to be able to rotate along the cylindrical outer circumferential surface of the rod portion 12, and the rotation of the rod portion 12 induces movement between the first state and the second state.

　[第２の実施の形態]
　続いて、図５から図６Ｂを参照して、本発明の第２の実施の形態のバルブ２について説明する。図５は本発明の第２の実施の形態のバルブ２の組立状態（左側）と分解状態（右側）のそれぞれの斜視図である。図６Ａは本発明の第２の実施の形態のバルブ２の断面図であって、バルブ２の開放状態を示している。図６Ｂは本発明の第２の実施の形態のバルブ２の断面図であって、バルブ２の閉鎖状態を示している。第２の実施の形態も基本的に第１の実施の形態と同様である。以下、第１の実施の形態との違いの部分を特に説明し、第１の実施の形態と同様な部分については、ある程度説明を割愛する。 [Second embodiment]
Next, a valve 2 according to a second embodiment of the present invention will be described with reference to Fig. 5 to Fig. 6B. Fig. 5 is a perspective view of the valve 2 according to the second embodiment of the present invention in an assembled state (left side) and in a disassembled state (right side). Fig. 6A is a cross-sectional view of the valve 2 according to the second embodiment of the present invention, showing the valve 2 in an open state. Fig. 6B is a cross-sectional view of the valve 2 according to the second embodiment of the present invention, showing the valve 2 in a closed state. The second embodiment is basically similar to the first embodiment. Below, differences from the first embodiment will be particularly described, and descriptions of similarities to the first embodiment will be omitted to some extent.

　第２の実施の形態のバルブ２も棒体部２２と管体２３とを備える。第２の実施の形態の棒体部２２は第１の実施の形態の棒体部１２と対応し、一端２２１と他端２２２とを備え、他端２２２が管体２３の第１流路２３３の内部に挿嵌されている点は第１の実施の形態と同じである。 The valve 2 of the second embodiment also comprises a rod portion 22 and a tube 23. The rod portion 22 of the second embodiment corresponds to the rod portion 12 of the first embodiment, and comprises one end 221 and the other end 222, and is the same as the first embodiment in that the other end 222 is inserted inside the first flow path 233 of the tube 23.

　一方、第２の実施の形態の棒体部２２は、管体２３の管路端部２３１を覆って管体２３の外面の外側にまで円筒状の形状として延在するカバー部材２２５を有している点が第１の実施の形態と異なる。第２の実施の形態の棒体部２２がカバー部材２２５を有している点以外は第１の実施の形態と同じである。 On the other hand, the rod portion 22 of the second embodiment differs from the first embodiment in that it has a cover member 225 that covers the pipe end portion 231 of the tube body 23 and extends in a cylindrical shape to the outside of the outer surface of the tube body 23. The rod portion 22 of the second embodiment is the same as the first embodiment except that it has a cover member 225.

　カバー部材２２５と管体２３の外周との一方には突起を備え、カバー部材２２５と管体２３の外周との他方には突起が嵌合して第１流路２３３の周方向に沿った方向に穿設される溝を備えている。 A protrusion is provided on one side of the cover member 225 and the outer periphery of the tube body 23, and a groove is provided on the other side of the cover member 225 and the outer periphery of the tube body 23, into which the protrusion fits and which is drilled in a direction along the circumferential direction of the first flow path 233.

　たとえば、代表的には、図５に示すように、管体２３の外周に突起２３５を備え、カバー部材２２５には第１流路２３３の周方向に沿った方向に穿設される溝２２６を備える。管体２３の外周に突起２３５はカバー部材２２５の溝２２６に係合される。 For example, as shown in FIG. 5, a protrusion 235 is provided on the outer periphery of the tube body 23, and a groove 226 is provided on the cover member 225 that is drilled in a direction along the circumferential direction of the first flow path 233. The protrusion 235 on the outer periphery of the tube body 23 engages with the groove 226 of the cover member 225.

　カバー部材２２５の溝２２６は管体２３の第１流路２３３の周方向に沿った方向に穿設されているので、カバー部材２２５は突起２３５の溝２２６内の移動によって、管体２３に対して回転し、これにより、棒体部２２が管体２３に対して回転する。 The groove 226 of the cover member 225 is drilled in a direction along the circumferential direction of the first flow passage 233 of the tube body 23, so that the cover member 225 rotates relative to the tube body 23 as the protrusion 235 moves within the groove 226, thereby causing the rod portion 22 to rotate relative to the tube body 23.

　第２の実施の形態においても、シール部材２３４は、管体２３の第１流路２３３を、第１流路２３３の軸方向に沿って管路端部の側の第１領域２３３aと第１領域よりも管路端部２３１から遠い第２領域２３３ｂとに分割する。 In the second embodiment, the sealing member 234 also divides the first flow path 233 of the tube body 23 along the axial direction of the first flow path 233 into a first region 233a on the side of the pipe end 231 and a second region 233b farther from the pipe end 231 than the first region.

　そして、第２の実施の形態においても、シール部材２３４は棒体部２２の外周面に密着しているので、第１流路２３３の第１領域２３３ａと第１流路２３３の第２領域との間では、流体の連通が絶たれている。 Also in the second embodiment, the seal member 234 is in close contact with the outer circumferential surface of the rod portion 22, so that fluid communication is cut off between the first region 233a of the first flow path 233 and the second region of the first flow path 233.

　棒体部２２は、棒体部２２の流路開口２２４が第１領域２３３ａに連通する第１状態（図６Ｂ）と、棒体部２２の流路開口２２４が第２領域２３３ｂに連通する第２状態（図６Ａ）と、の間の移動が可能である。 The rod portion 22 can move between a first state (FIG. 6B) in which the flow passage opening 224 of the rod portion 22 is connected to the first region 233a, and a second state (FIG. 6A) in which the flow passage opening 224 of the rod portion 22 is connected to the second region 233b.

　これにより、第２の実施の形態においても、棒体部２２の第１状態（図６Ｂ）と第２状態（図６Ａ）との間の移動が喚起される。 As a result, even in the second embodiment, movement of the rod portion 22 between the first state (Figure 6B) and the second state (Figure 6A) is induced.

　すなわち、第２の実施の形態のバルブ２においても、第１状態（図６Ｂ）において、第２流路２２３と第１流路２３３との流体の連通を閉止し、第２状態（図６Ａ）において、図６Ａの矢印のような、第２流路２２３と第１流路２３３との間の流体の流れを喚起する。 In other words, in the valve 2 of the second embodiment, in the first state (FIG. 6B), the fluid communication between the second flow path 223 and the first flow path 233 is closed, and in the second state (FIG. 6A), the flow of fluid between the second flow path 223 and the first flow path 233 is induced as shown by the arrows in FIG. 6A.
