Figure 112011503480433-utm00003
In the case of fastening the ring to the threaded boundary of the water pipe, the gap is formed by trapping a rectangular through hole in the front connection surface and connecting the connection part with a string to the conical packing rear surface which constitutes the slope. And the water pressure is measured so as not to be leaked by compressing and contacting the threaded inlet interface of the water pipe in the state of being maintained in a state of being maintained. Contrary to the configuration of the conical packing, cross-shaped through holes and spaces are formed in the conical packing, and the conical locking holes are integrally connected with the connecting straps to protrude to the pipe plug connection surface, and connected with the connecting straps so as to be integrated with the pipe plugs. The conical locking hole is inserted into the cross-shaped through hole of the packing, and then fixed. So it will be able to easily drew designed to improve one of the earlier application.

상기와 같은 선출원의 원뿔상의 패킹 후면에 연결부를 끈으로 하여 일체로 된 사다리꼴형 걸림구를 배관마개 전면 접속면에 통공된 직사각형 통공에 끼워서 배관마개를 뺄 때, 원뿔상의 패킹이 딸려 나와서 패킹을 편리하게 해체할 수 있도록 구성한, 상기 선출원도 수압측정 후 해체할 때 패킹의 탈리 시키기가 용이하나 본 고안에서는 반대로, 원뿔상의 패킹 후면에 십자형 통공과 공간부를 구성하고, 배관마개 나선부 전면의 접속면에는 연결끈과 일체로 된 원뿔형 걸림구를 돌출되게 구성하여, 상기 원뿔상의 패킹 후면에 구성된 십자형 통공과 공간부에 상기 걸림구를 끼워서 수도배관에 결착하여 수압을 측정한 후, 배관마개를 해체하여 뺄 때에 원뿔상의 패킹이 원뿔상의 걸림구에 걸려서 용이하게 탈리시킬 수 있다는 점에 착안하여 상기 선출원 고안의 방어적인 목적으로 안출한 것이다.When the pipe plug is removed by inserting an integrated trapezoidal latch with a connection part to the conical packing rear surface of the above-mentioned filings into a rectangular hole through the front connection surface of the pipe stopper, the packing with the conical shape comes out for convenient packing. The first application, which is configured to be dismantled so that it is easy to detach the packing when dismantling after the hydraulic measurement, but in the present design, the cross-shaped through hole and the space is formed on the conical packing rear side, Conical hooks integrated with connecting strings are formed to protrude, and the hooks are inserted into the cross-shaped through holes and spaces formed on the back of the conical packing, and the water pressure pipes are measured to measure the water pressure. The above-mentioned filing, paying attention to the fact that the conical packing can be easily detached by being caught by the conical latch. It is designed for the defensive purpose of the devise.

After condensing and tightening the pipe stopper to prevent water leakage at the time of measuring water pressure, and to easily detach the packing, conical hanger connected by the connecting string to the front connection surface of the pipe stopper is integrally projected. It is designed to be inserted into the cross-hole and space part formed in the conical packing, inserted into the front connection surface of the water pipe, and then tightened by the pipe plug to compress it so that the packing can be easily detached after measuring water pressure without leaking. It is effective.
