본 고안은 화학물 또는 유류등의 송수관이나 고압가스관등을 배관할때 효율적으로 연결 접속시킬 수 있게한 강관용 연결장치에 관한 것으로, 이를 좀더 구체적으로 설명하면 일정단위 길이로 형성된 강관을 상호 연결하는 관접부에 양측 강관의 간격유지를 위한 결속부재를 이용하여 상호 결합하여 주되, 결속부재와 강판사이에 개제시키는 패킹부재에 선단받침턱과 후측연장부를 내광외협의 경사면으로 구비시켜 선단받침턱은 강관의 선부가 직접 접촉하는 것과 결속부재에 직접 접하는 것을 방지토록 하였으며, 압착부재의 내경사면과 밀접되는 상태에 강관에 결속되는 스크류가 패킹부재의 우측연장부를 관통하여 결속 되어지므로 밀폐기능이 양호하여 외기로 인한 부식이나 파손을 방지하여 줄수 있게할 목적으로 고안한 것이다.The present invention relates to a steel pipe connecting device that can be efficiently connected when connecting a water pipe or a high-pressure gas pipe, such as chemicals or oil, more specifically to explain the interconnection of steel pipe formed in a certain unit length The joints are joined to each other by using a binding member for maintaining the gap between the two steel pipes, but the front support base and the rear extension are provided as the inclined surface of the light and narrow narrow space in the packing member to be interposed between the binding member and the steel plate. To prevent direct contact between the line part of the wire and direct contact with the binding member.The screw connected to the steel pipe is bound through the right extension part of the packing member while being in close contact with the inner inclined surface of the crimping member. It is designed to prevent corrosion or damage caused by
종래에도 여러종류의 강관 연결장치가 사용되어지고는 있으나, 현재까지 사용되고 있는 연결장치들은 대개가 복잡한 구조로 되어져 있을뿐만 아니라 이를 조립하기 위하여는 숙련된 자만이 조립이 가능하였고 작업시간과 많이 소요되었다.Conventionally, various types of steel pipe connecting devices are used, but the connecting devices used up to now have not only a complicated structure, but only a skilled person was able to assemble them, and it took much time and work. .
그리고 복잡한 구조인 만큼 제작비도 고가이어서 비경제적이었으며 양 연결강관을 긴밀하게 연결하여 주지못하여 관접부위가 견고하기 못함으로 인하여 고압송수시에는 관접합부에 별개의 보강장치를 부설하여야 하는 등의 불편이 있었다.In addition, due to its complicated structure, the manufacturing cost was expensive and it was uneconomical.Therefore, it was inconvenient to install a separate reinforcing device in the pipe joint during high pressure transmission because the pipe joint was not firmly connected because it could not connect the two steel pipes closely. .
이를 보완하여 본원인이 선출원한 실용신안등록출원 제89-13276호가 개발사용되고 있으나, 이는 결속부재를 이용하여 강관과 패킹사이의 기밀을 유지하고 압착부재로 패킹의 밀폐효과를 증대시키고 있으나 사용중 강관과 압착부재의 접촉면이 벗겨져 부식되는 등의 문제점이 있어 실용적이 못되었다.Complementary to this, Utility Model Registration Application No. 89-13276, filed by the applicant, has been developed and used, but it uses the binding member to maintain the airtightness between the steel pipe and the packing and increases the sealing effect of the packing with the crimping member. The contact surface of the crimping member is peeled off and there is a problem such as corrosion has not been practical.
본 고안은 종래의 이와같은 제반 문제점에 착안하여 양쪽 강관이 직접적으로 접촉되는 것을 방지하여 줄수 있게된 패킹부재를 끼워 설치하되 패킹부재의 선단에는 내향 받침턱을 구비시켜 강관의 상호 직접 접촉을 방지하였고 후측으로는 연장부를 일체형으로 형성시켜 주어 압착부재로 패킹부재를 압압밀착하여 줄때 압착부재가 직접 강관과 접촉하지 못하도록 패킹부재로 결속부위 전체를 씌워주므로서 외기에 의한 부식이나 누수현상을 방지하고 밀폐효과를 증대시킬 수 있게한 것으로, 이를 첨부도면에 의하여 상세히 설명하면 다음과 같다.The present invention has been made in view of the above-mentioned problems in the prior art by installing a packing member that can be provided to prevent the direct contact of both steel pipes, but provided with an inward supporting jaw at the tip of the packing member to prevent mutual direct contact of the steel pipes On the rear side, the extension part is formed integrally, and when the pressing member is pressed against the packing member, the entire packing part is covered with the packing member so that the pressing member does not come into direct contact with the steel pipe. In order to increase the effect, it will be described in detail by the accompanying drawings as follows.
제 1 도는 본 고안의 전체적인 조립상태를 알아보기 쉽게 나타낸 일부 절결단면도로써, 부호(1)과 (1-1)은 연결시키고자 하는 양측강관을 나타낸 것으로 이 강관(1)(1-1)들은 일정간격을 두고 서로 마주보도록한 위치에서 연결되어진다.Figure 1 is a partial cut-away cross-sectional view showing the overall assembly state of the present invention easy to see, reference numerals (1) and (1-1) represent the two steel pipes to be connected to this steel pipe (1) (1-1) They are connected at positions facing each other at intervals.
이 강관(1)(1-1)의 연결부위의 외주연에 설치되는 압착부재(3)에는 그 외주에 다수개의 스크류공(3-2)을 갖고 있어 스크류(7)를 나사조임 할수 있도록 되어있으며, 통상의 연결볼트(5)가 통과하여 너트(6)로 반대측 압착부재(3)와 결합하게 되어 있다.The pressing member 3 installed on the outer circumference of the connecting portion of the steel pipe 1, 1-1 has a plurality of screw holes 3-2 on its outer circumference so that the screw 7 can be screwed on. The connecting bolt 5 passes through and is coupled to the opposite side pressing member 3 by a nut 6.
이 압착부재(3)들의 사이에는 내부에 간격유지부(2-2)와 외측으로 갈수록 상향경사진 양날래(2-1)가 일체로 구비된 결속부재(2)를 개재하여서된 것이다.Between the crimping members 3, the gap holding part 2-2 is interposed between the pressing members 3 and the binding member 2 integrally provided with two edges 2-1 inclined upward.
패킹부재(4)의 내주면은 연결시키고져 하는 강판의 외주면과 평행을 이루도록 되어 있으며, 다만 패킹부재의 선단에는 내향진 받침턱(4-1)이 일체형으로 구비되어져 강관(10(1-1)의 선단과 결속부재(2)의 내면이 직접접촉하지 못하도록 하였으며 후방으로는 후측연장부(4-2)가 일정길이만큼 연장되어져 있되, 후측연장부(4-2)의 외면은 뒤로 갈수록 점차 하양경사진 경사면(4-2a)을 이루게 하여 압착부재(3)의 내경사면(3-1)과 동일한 경사상태에서 연결볼트(5)를 너트(6)로 조이면 간격이 좁혀지며 압착부재(3)의 내경사면(3-1)이 패킹부재(4)의 경사면(4-2a)을 타고 슬라이드하여 패킹부재를 압압하여 주게되는 것이다.The inner circumferential surface of the packing member 4 is formed to be parallel to the outer circumferential surface of the steel sheet to be connected, except that the inwardly facing support jaw 4-1 is integrally provided at the tip of the packing member so that the steel pipe 10 (1-1) The front end and the inner surface of the binding member 2 are not directly contacted, and the rear extension 4-2 is extended by a certain length in the rear, but the outer surface of the rear extension 4-2 gradually descends toward the rear. When the connecting bolt 5 is tightened with the nut 6 in the same inclined state as the inner inclined surface 3-1 of the crimping member 3 to form an inclined inclined surface 4-2a, the spacing is narrowed and the crimping member 3 is The inner inclined surface (3-1) is to slide on the inclined surface (4-2a) of the packing member 4 to press the packing member.
이때 양측강관(1)(1-1)이 직접 접촉하지 못하도록 외부에서 일정간격을 유지시켜 주는 결속부재(2)의 중앙간격유지부(2-2)는 패킹부재(4)의 받침턱(4-1)을 지지하여 주고 결속부재(2)의 양날개(2-1)는 외향으로 가면서 차차 상향경사상태를 이루고 있으며 이에 내재되는 패킹부재는 결속부재의 양날개와 동일 경사각도를 이루고 있게 하여 결속부재(2)가 패킹부제(4)에 의하여 강관(1)(1-1)과 긴밀한 결속상태를 이루게한 것이다.At this time, the center interval holding portion (2-2) of the binding member (2) that maintains a constant distance from the outside so that the two steel pipe (1) (1-1) does not directly contact the supporting jaw (4) of the packing member (4) -1) and both blades (2-1) of the binding member (2) is gradually inclined upward toward the outward direction, and the packing member inherent to achieve the same inclination angle as both wings of the binding member The binding member 2 is to form a close binding state with the steel pipe (1) (1-1) by the packing subsidiary (4).
상기한 두 강관(1)(1-1)의 결합상태를 전체적으로 설명하면 먼저 일측 강관(1)에 압착부재(3)를 삽입하여 준 상태에서 패킹부재(4)를 강관(1)외주에 제 4a 도와 같이 삽입한 다음 결속부재(2)를 개재시켜 반대측강관(1-1)에도 상술한 상태로 압착부재와 패킹부재를 삽입하여 주고 이들을 결속부재(2)로 결속하여 주고 볼트(5)와 너트(6)로 양측의 압착부재(3)를 나사 조입하여 주면 결속부재의 경사면과 패킹부재의 경사면이 경사모멘트를 받아 결속부재가 패킹부재를 압압하므로서 결과적으로 패킹부재가 강관을 긴밀하게 밀착하여주는 조립상태가 이루어진다.Referring to the combined state of the two steel pipes (1) (1-1) as a whole, first, the packing member (4) to the outer periphery of the packing member (4) in the state in which the pressing member (3) is inserted into one side of the steel pipe (1) Insert it together with the 4a diagram, and then insert the pressing member and the packing member into the opposite side steel pipe (1-1) through the binding member (2) and bind them to the binding member (2), and the bolt (5) and By screwing the two pressing members 3 together with the nut 6, the inclined surface of the binding member and the inclined surface of the packing member receive the inclined moment, and the binding member presses the packing member so that the packing member closely adheres to the steel pipe. The state is assembled.
이때 결속부재의 간격유지부가 양측 패킹부재의 선단 받침턱이 서로 맞닿아 결합이 이루어지고 받침턱내면에 삽입 되어있는 강관의 선단은 받침턱에 의하여 직접 결속부재에 접촉되는 것을 방지하게 되는 것이다.At this time, the gap retaining portion of the binding member is coupled to each other by the front end of the packing member is in contact with each other, and the tip of the steel pipe inserted into the inner surface of the base is prevented from contacting the binding member directly by the base.
이와같은 상태에서 볼트와 너트로 조임을 하여 주면 압착부재(3)의 내경사면(3-1)과 패킹부재(4)의 경사면(4-2a)사이에도 동시에 경사 모멘트가 작용하여 결합이 이루어짐과 동시에 압착부재의 선부가 패킹부재의 압압면(4-3)을 압압하여 긴밀한 결합이 이루어진 상태에서 압착부재(3)의 외면에 형성된 다수의 스크류공(3-2)에 스크류(7)를 나사조임하여 주게되면 스크류(7)는 스크류공을 통과하여 패킹부재(4)를 파고들어 강관(1)(1-1)의 표면을 압지하도록 결합하여서된 것이다.In this state, by tightening with bolts and nuts, the inclined moment acts simultaneously between the inclined surface 3-1 of the pressing surface 3 and the inclined surface 4-2a of the packing member 4, thereby making the coupling. At the same time, the screw 7 is screwed into a plurality of screw holes 3-2 formed on the outer surface of the pressing member 3 in a state where the pressing portion of the pressing member presses the pressing surface 4-3 of the packing member to form a tight coupling. When tightened to tighten the screw (7) is to pass through the screw hole to dig the packing member (4) to combine to press the surface of the steel pipe (1) (1-1).
이와같이 스크류가 강관표면의 피막층을 뚫고 견고하게 결속되어지게 하면 사용중 진동이나 온도변화 등에도 그 결속상태가 영향을 받지 않을 뿐만 아니라 압착부재(3)가 결합위치에서 이탈되는 것을 방지하는 목적으로 이용되는 스크류(7)가 압착부재(3)의 스크류공(3-2)을 통과하여 직접 강관의 표면만을 압지하여 주도록 되어 있지 않고 패킹부재(4)의 후측연장부(4-2)를 강제로 뚫고 들어가 강관에 끝단이 맞닿아 조여진 상태이므로 외부의 기후변화에도 불순물이 침투되지 못하여 스크류공 또는 스크류의 끝단이 압지되는 강관의 표면에 외부의 불순물이 침투되어 부식되는 것을 방지할 수 있도록 패킹부재가 밀폐시켜주는 효과를 동시에 얻을 수 있게 한것이다.In this way, if the screw penetrates the film layer on the surface of the steel pipe and is firmly bound, the binding state is not affected by vibration or temperature change during use, and it is used for the purpose of preventing the crimping member 3 from being released from the engaged position. The screw (7) passes through the screw hole (3-2) of the crimping member (3) to directly press the surface of the steel pipe, and forcibly drills the rear extension (4-2) of the packing member (4) The packing member is sealed to prevent the external impurities from penetrating into the surface of the screw hole or the steel pipe where the end of the screw is pressed because the impurity does not penetrate even when the outside end is in contact with the steel pipe. The effect is to get at the same time.
그리고, 연결볼트(5)와 너트(6)의 결속상태가 진동등에 의하여 느슨하여지므로써 양측 강관사이에 끼워 설치된 패킹부재를 압압하여 주고 있는 결속부재와 압착부재의 결착상태가 견고하지 못하여져도 압착부재(3)를 두 강관(1)(1-1)사이에 결속시키고 있는 스크류(7)가 패킹부재를 강제로 뚫고 들어간 상태에서 강관의 표면을 압지하고 있어 결속기능이 배가 되어지므로서 압착부재(3)가 볼트와 너트의 결속상태가 느슨하여짐만으로는 뒤로 물러나게 되지 않게 하여주는 기능을 배가하게 한것이다.In addition, since the binding state of the connecting bolt 5 and the nut 6 is loosened by vibration or the like, the compression of the binding member and the pressing member, which presses the packing member inserted between the two steel pipes, is insufficient. The screw 7, which binds the member 3 between the two steel pipes 1, 1-1, presses the surface of the steel pipe in a state where the packing member is forced through the packing member. (3) doubles the function that prevents the bolt and nut from loosening back just by loosening.
따라서 강관내를 고압으로 흐르는 가스나 유체가 관내에서 누출하거나 주수되지 않게하여주는 것이다.Therefore, the gas or fluid flowing at high pressure in the steel pipe does not leak or pour in the pipe.
이와같은 상태로 사용할수 있게된 본 고안의 강관연결장치는 밀폐기능을 갖춘 패킹부재에 선단 받침턱과 후측연장부를 일체로 구비시켜 놓아 강관의 선단이 결속부재에 직접 접촉되는 것을 받침턱이 방지하여 주고 강관이 필요이상 깊게 삽입되는 것을 방지하였으며, 특히 본 고안의 강관 연결장치에서는 패킹부재의 후측연장부의 표면을 후측하양 경사면으로 하여 압착부재의 내경사면과 경사모멘트를 이루게하여 결속력을 배기함과 동시에 압착부재를 강관에 고정시키는 스크류가 패킹부재의 후측연장부를 강제로 뚫으면서 강관에 스크류끝단이 압지되게 하여 노출된 상태에서 자연적이거나 인위적인 주위환경과 기후의 변화에도 강관이나 스크류가 부식되는 것을 방지하여 주는 효과를 얻게 한 것이다.The steel pipe connecting device of the present invention, which can be used in such a state, is provided with a sealing member with a front end support and a rear extension unit integrally to prevent the support from directly contacting the end of the steel pipe with the binding member. In addition, the steel pipe is prevented from being inserted deeply more than necessary. Especially, the steel pipe connecting device of the present invention makes the surface of the rear extension part of the packing member the rear side inclined surface to form the inclined moment with the internal inclined surface of the crimping member to exhaust the binding force. At the same time, the screw fixing the crimping member to the steel pipe forcibly penetrates the rear extension of the packing member, and the screw tip is pressed into the steel pipe to prevent the steel pipe or screw from being corroded under natural or artificial environmental conditions and climate changes in the exposed state. It will give you the effect.
이와같은 본 고안의 강관 연결장치는 그 구조가 매우 간단하여 조립성이 우수하면서도 긴밀성을 유지할 수 있는 호환성 있는 제품을 저렴한 가격으로 생산, 판매할 수 있도록 한 매우 실용적이고도 유용한 고안이다.Such a steel pipe connecting device of the present invention is a very practical and useful design that allows the production and sale of a compatible product that can maintain the closeness and excellent assembly ability at a low price due to its very simple structure.
