Description

관 조인트{Pipe Joint}Pipe Joint

본 고안은 관 접속단에 조인트에 의해 옥죄어지는 환상 돌출테가 부여된 관 접속력을 강화할 수 있게 한 관 조인트에 관한 것이다.The present invention relates to a pipe joint that makes it possible to reinforce a pipe connection force given to an annular protruding frame that is constricted by the joint at the pipe connection end.

접속단 가까운 곳에 롤링 혹은 벌지가공으로 환상의 돌출테를 부여한 관과 관을 접속하기 위한 관 조인트중에는 내주면의 외측단에 상기 돌출테를 바깥에서 안쪽으로 거는 단턱형태의 단일 소경관부를 가진 것이 있다.One of the pipe joints for connecting the pipe and the pipe to which the annular protruding frame is provided by rolling or bulge processing near the connection end has a single small diameter pipe part of the stepped shape that hangs the protruding frame from the outside to the inside of the inner circumferential surface.

바깥걸림용 소경관부는 조인트로 접속한 관이 접속방향과는 반대쪽으로 밀려나지 못하게 막을 수는 있지만 접속단쪽으로 수축되는 것은 저지할 수가 없다.The outer locking small diameter pipe part can prevent the pipe connected by the joint from being pushed in the opposite direction to the connection direction, but it cannot prevent the contraction toward the connection end.

또, 접속한 관의 접속단이 줄어들거나 줄어든 만큼 혹은 그 이상의 늚이 반복되다보면 접속단과 조인트 소경관부와의 상호 마찰로 인하여 이들 간에 틈이 생겨 내부 유체가 누설되는 불상사가 발생한다.In addition, when the connection end of the connected pipe is reduced or reduced, or more times, the repeated friction between the connection end and the joint small diameter tube part causes a gap between them, resulting in an injured accident in which internal fluid leaks.

본 고안은 접속단 가까운 곳에 환상의 돌출테가 부여된 관의 접돌출테 안팎을 동시에 걸어서 가둘 수 있는 구조로 개조함으로서 관 접속단에 대한 접속안정성을 일층 강화한 관 조인트를 제공하는 것이 주된 특징이다.The present invention is to provide a pipe joint that further strengthens the connection stability to the pipe connection by converting it into a structure that can be trapped at the same time inside and outside the contact frame of the pipe that is given an annular protruding frame near the connection end.

1 ; 조인트 부재 3 : 환상 돌출테One ; Joint member 3: annular protrusion frame

4 : 외측 소경관부 5 : 내측 소경관부4: outer small diameter tube portion 5: inner small diameter tube portion

도 1에서, 원주를 반분하여 두 조각낸 한쌍의 조인트 부재(1)의 내주면에 관(2)의 접속단에 주어진 환상 돌출테(3)에 바깥걸림되는 소경관부(4)가 형성되어 있다. 이 소경관부(4)는 조인트 부재(1)의 내면 일측에만 주어진 것과 양쪽에 주어진 것이 있다. 여기서 본 고안은 관(2)의 환상 돌출테(3)를 바깥걸림시키기 위한 소경관부(4)를 외측 소경관부로 하고, 그 안쪽으로 조금 떨어진 곳에 상기 환상 돌출테(4)의 안쪽을 거는 내측 소경관부(5)를 추가로 형성한 것이다.In Fig. 1, a small diameter tube portion 4 is formed on the inner circumferential surface of a pair of joint members 1 cut in two halves of the circumference, and hung outside the annular protruding frame 3 given to the connecting end of the tube 2. This small diameter tube part 4 is given only to one side of the inner surface of the joint member 1, and is given to both sides. In the present invention, the small diameter tube portion 4 for locking the outer annular protrusion frame 3 of the tube 2 is the outer small diameter tube portion, and the inner side hanging the inner side of the annular protrusion frame 4 a little inwardly. The small diameter pipe part 5 is further formed.

양 소경관부(4,5)의 내면간 최단거리는 환상 돌출테(3)의 폭(w)을 넘지 않고 안팎 턱걸림이 확실히 이뤄질 수 있는 범위내로 한정한다. 소경관부(4,5)간의 최단거리가 환상 돌출테(3)의 폭(w)보다 넓으면 신축변화를 억제할 수 없고 안팎의 턱걸림이 불가능한 것은 본 고안의 취지를 벗어난다.The shortest distance between the inner surfaces of both small diameter tube portions 4 and 5 is limited to the range within which the jaw can be secured inside and outside without exceeding the width w of the annular protruding frame 3. If the shortest distance between the small diameter tube portions 4 and 5 is wider than the width w of the annular protruding frame 3, the elastic change cannot be suppressed and the jaw inside and outside cannot be caught, which is beyond the scope of the present invention.

조인트 부재(1)로 환상 돌출테(3)가 부여된 두 개의 관(2)의 접속단을 맞대고 겉에 조인트 부재(1)를 씌운 다음 플랜지에 보울트(6)를 체결하는 순서로 관을접속하며, 접속된 후는 도 1,2와 같다. 이들 그림에서 보듯이, 관(2)의 접속단에 부여된 환상 돌출테(3)는 소경관부(4)에 의해 바깥걸림되고 내측 소경관부(5)에 의해서는 안쪽이 걸려 있다.The pipes are connected in the order of joining the connecting ends of the two pipes 2, to which the annular protruding frame 3 is attached to the joint member 1, covering the outside with the joint member 1, and then fastening the bolt 6 to the flange. After the connection is as shown in Figs. As shown in these figures, the annular protruding frame 3 applied to the connecting end of the tube 2 is caught by the small diameter tube portion 4 and is hung inside by the inner small diameter tube portion 5.

이처럼 환상 돌출테(3)의 안팎이 소경관부(5,4)에 갇히듯이 걸림에 따라 간(2)는 축방향으로 일절 움직이지 못한다. 이같은 현상은 관(1)이 열을 받든 안받든 마찬가지다.As described above, the liver 2 does not move at all in the axial direction as the inside and the outside of the annular protruding frame 3 are trapped in the small diameter tube portions 5 and 4. This phenomenon is the same whether the tube 1 is heated or not.

이상 설명한 바와 같은 본 고안의 관 조인트는 접속단 부근에 환상 돌출테가 주어진 관을 접속할 때 그 환상 돌출테의 안쪽마저 내측 소경관부에 걸리고, 결국은 안팎의 소경관부에 의하여 환상 돌출테가 꼼짝도 못하게 갇힘으로써 관 접속단의 신축작용에도 불구하고 접속상태가 확고하다.As described above, the pipe joint of the present invention is caught in the inner small diameter tube portion even when the inner tube of the annular protrusion is connected near the connecting end, and eventually the annular protrusion is stuck by the inner and outer small diameter tube portions. By being locked up, the connection is firm despite the expansion and contraction of the pipe connection.
