Abstract

본 고안은 관 접속상태를 강화시키기 위하여, 원주를 반분하여 두조각낸 한쌍의 조인트 부재(1a, b)의 내주면에 관의 접속단 외부면에 접속하는 호상의 단턱(2)이 형성 된 관 조인트의 상기 단턱(2)의 내주면 안쪽에는 미늘(3)을 형성하고, 미늘(3)의 외측에는 관 접속단옥죔용 링을 수용하기 위한 링홈(4)을 형성하고 거기다 링(8)을 끼운 것이다.The present invention provides a pipe joint in which an arcuate step (2) is formed on the inner circumferential surface of a pair of joint members (1a, b) divided into two halves of the circumference to connect to the outer surface of the connection end of the tube in order to strengthen the pipe connection state. A barb 3 is formed inside the inner circumferential surface of the step 2, and a ring groove 4 is formed on the outside of the barb 3 to accommodate a ring for pipe connection monoblock.

Description

관 조인트(Pipe Joint)Pipe Joint

관의 접속상태를 강화할 목적하에 개발된 본원인의 선출원 고안중 실용신안 등록출원 제97-135331호는 조인트 부재의 내주면에 관의 접속단 외면을 얕게 파고 들어가 박히는 날쐐기(미늘)를 형성한 것이고, 실용신안등록출원 제97-135331호는 관의 접속단에 주어진 오목한 링홈에 금속링을 끼우고 양쪽 금속링을 조인트로 끌러당기듯 옥죄어서 접속하는 구조의 것이다.Utility Model Registration Application No. 97-135331 of the applicant's prior application design developed for the purpose of reinforcing the connection state of the pipe is formed on the inner circumferential surface of the joint member to form a blade wedge which penetrates the outer surface of the pipe shallowly. , Utility Model Application No. 97-135331 is of a structure in which a metal ring is inserted into a concave ring groove given at a connection end of a pipe, and both metal rings are pulled together by a joint.

이러 류의 관 조인트는 특히 계절별 대기, 실내, 관로내의 유체의 온도변화에 따른 관의 신축작용, 특히 관 접속단에서의 신축작용에 따른 길이의 변화가 감지되지 않을 정도로 극미해야 만이 관 접속부위에서의 유체의 기밀유지에 이롭다.This type of pipe joint should only be so small that the change in length due to the temperature change of the fluid in the atmosphere, the room and the pipeline, especially the length change due to the expansion and contraction at the pipe joint, should be minimal. It is beneficial to keep the fluid tight.

그런데, 상기한 선행기술의 관 조인트가 지닌 미늘, 링과 링을 옥죄는 소경관부만으로는 관접속단의 신축변화를 줄이는데 한계가 있기 때문에 관로내의 유체에 대한 안전보장에 문제가 있다.However, since the small diameter tube part of the prior art pipe joints of the prior art pipe joints has limitations in reducing the expansion change of the pipe ends, there is a problem in the safety of the fluid in the pipeline.

한편, 일본국 특개 평4-102792호의 관계수에 형성된 돌기연은 본관에 천공된 분기공에 끼웠을 때 그 분기공의 내측 언저리에 걸리게 하기 위한 턱걸림 수단이며 접속된 관의 살을 파고 들어가 박힘으로써 관의 접속력을 강화하는 것과는 무관하다.On the other hand, the projections formed in the relationship tree of Japanese Patent Application Laid-Open No. 4-102792 are jawing means for being caught in the inner circumference of the branch hole when inserted into the branch hole drilled in the main building. It has nothing to do with enhancing connectivity.

본 고안은 상기한 미늘, 링-소경관부구조의 문제점을 해소하기 위한 것으로, 미늘과 링-소경관부를 복합적으로 절충시켜 관접속시 각 관의 접속단을 보다 확고하게 물어줌으로써 관 접속상태를 더욱 공고히 할 수 있게 한 조인트를 제공하는 것을 주된 특징으로 한다.The present invention is to solve the problems of the barb, the ring-small diameter tube structure described above, by combining the barb and the ring-small diameter tube part in combination to make the pipe connection state more firmly by asking the connection end of each pipe when the pipe connection It is a main feature to provide a joint that allows for solidification.

제1도는 본 고안의 일시예에 의한 관 조인트의 부분절개 정면도.1 is a partial cutaway front view of the tube joint according to one embodiment of the present invention.

제2도는 상기 조인트로 두 개의 관을 접속한 경우의 부분절개 정면도.2 is a partial cutaway front view when two pipes are connected by the joint.

제3도는 다른 실시예에 의한 관 조인트로 관을 접속한 상태의 다면예시도.3 is a multi-faceted view of a state in which a pipe is connected by a pipe joint according to another embodiment.

제1도에서, 운주를 반분하여 두조각낸 한쌍의 조인트 부재(1a, b)의 내주면에 관의 접속단 외주면에 접촉하는 호상의 단턱(2)이 형성된 것에 있어서, 상기 단턱(2)의 내주면 안쪽에는 미늘(3)을 형성하고, 미늘(3)의 외측에는 링홈(4)을 형성한다.In Fig. 1, the inner circumferential surface of the stepped portion 2 is formed in the inner circumferential surface of the pair of joint members 1a and b that is divided into two halves in contact with the outer circumferential surface of the connection end of the tube. A barb 3 is formed inside, and a ring groove 4 is formed outside the barb 3.

미늘(3)은 끝이 예리한 물림날의 형태이다. 미늘(3)의 생김새는 도시한 대로 평행한 환상의 미늘을 축방향을 따라 피치간격으로 촘촘히 늘어세운 것, 넓은 간격으로 배치한 것, 또는 원주를 따라 간헐적으로 배치한 원주분할형 등이 있다.The barbs 3 are in the form of sharp edges. The appearance of the barbs 3 includes, as shown, densely arranged parallel annular barbs at pitch intervals along the axial direction, arranged at wide intervals, or a circumferential split type arranged intermittently along the circumference.

링홈(4)은 관의 접속단에 형성한 대립형 링홈에 끼운 링을 바깥쪽에서 걸어 가둬서 옥죄이기 위한 것으로, 끝이 각이 진 U홈의 형태를 취하고 있다. 이 링홈(4)에는 링(8)을 들어 앉힌다. 링(8)은 금속링이자 일점이 열린 C형 링이며, 던싱을 지닌 것이면 더욱 좋다.The ring groove 4 is for imprisonment by trapping a ring fitted in an opposing ring groove formed at the connection end of the pipe from the outside, and is in the form of a U groove having an angled end. The ring 8 is seated in the ring groove 4. The ring 8 is a metal ring and a C-type open ring, and more preferably, it has a duncing.

제2도에서, 좌, 우측 관(5a, b)의 단부를 통하여 각 링홈(7)에 링(8)을 미리 끼운 다음 양 조인트 부재(1a, b)를 쒸운다. 이때, 조인트 부재(1a, b)의 좌, 우 링홈(4)은 각자 자기 위치에 놓인 링(8)을 덮어 쒸운다.In FIG. 2, the ring 8 is pre-inserted into each ring groove 7 through the ends of the left and right tubes 5a and b, and then the both joint members 1a and b are sandwiched. At this time, the left and right ring grooves 4 of the joint members 1a and b cover and cover the ring 8 positioned at their respective positions.

이 상태에서 마주보고 맞닿는 조인트 부재(1a, b)의 플랜지(5)에 보울트(9)를 체결하여 조인다. 보울트(9)의 체결압력이 가중되면서 미늘(3)은 관(5a, b)의 접속단 외주면을 파고 들어가고 링홈(4)은 링(8)을 향심방향으로 옥죈다.In this state, the bolt 9 is fastened by tightening the bolt 9 to the flange 5 of the joint members 1a and b facing each other. As the clamping pressure of the bolt 9 is increased, the barbs 3 dig into the outer circumferential surfaces of the connecting ends of the pipes 5a and b, and the ring grooves 4 are directed toward the ring 8 in the direction of the center.

이와 같이 미늘(3)이 관(5a, b)의 살 속에 박히고 링(8)을 통하여 관(5a, b)의 접속단을 옥죔에 따라 관(5a, b)은 미늘단독, 링단독에 의한 접속상태 보다도 훨씬 강력한 접속상태로 존속하게 된다.Thus, the barbs 3 are embedded in the flesh of the pipes 5a and b, and the pipes 5a and b are formed by the barbed sole and the ring sole as the roof ends the connection ends of the pipes 5a and b through the ring 8. It stays in a much stronger connection than it is.

제3도에서, 일측 단턱(2)에는 상기와 마찬가지로 미늘(3)을 부여함과 동시에 링홈(4)을 형성하여 링(8)을 끼우고, 타측 단턱(2a)에는 각이 진 소경관부(10)를 형성하여 그 수경관부(10)에 부합되는 홈(11)을 가진 관(12)과 상기한 링홈(7)을 가진 관(5a) 또는 (5b)의 접속에 쓰이도록 변경한 관 조인트이다. 여기서도 미늘(3)과 링홈(4) 및 링(8)의 역할은 제1실시예에 동일하다.In FIG. 3, the one end step 2 is provided with the barbs 3 in the same manner as described above, and at the same time, the ring groove 4 is formed to fit the ring 8, and the other end step 2a has an angled small diameter tube part ( 10) a tube joint modified to be used to connect the tube 12 having the groove 11 corresponding to the hydroponic tube part 10 and the tube 5a or 5b having the ring groove 7 described above. to be. Here too, the roles of the barbs 3, the ring grooves 4 and the rings 8 are the same as in the first embodiment.

이상 설명한 바와같이 본 고안에 의해 새로 제안된 관 조인트는 접속할 두 개의 관 접속단의 살을 파고 들어가 박히는 미늘과 흠걸이한 상태에서 옥죄는 링을 끼울 링홈을 형성함으로써 미늘만 가진 간 조인트, 링홈만이 주어진 관조인트에 비해 관 접속강도를 한층 높일 수 있다. 새로운 구조의 관 조인트는 고압유체용 관로의 구축, 열안정성이 요구되는 관로구축에 특히 적합하다.As described above, the tube joint newly proposed by the present invention is a barb that has only barbs and a ring groove by forming a ring groove into which a ring is inserted into the ring in the state of being dug into the barbed and flawed state of the two pipe joints to be connected. The pipe joint strength can be further increased compared to the given pipe joint. The new pipe joint is particularly suitable for the construction of high pressure fluid pipelines and pipeline construction requiring thermal stability.

본 고안은 관접속용 조인트의 개량에 관한 것이며, 특히 관 접속상태의 강화에 목적을 둔 관 조인트에 관한 것이다.The present invention relates to an improvement in a joint for pipe connection, and more particularly, to a pipe joint aimed at reinforcing a pipe connection state.
