본 고안은 액체관의 수격 방지구에 관계되는 것으로서, 특히 원동형 몸체 상단에 부착된 고정링의 절곡연부와 덮개판의 절곡연부사이에 완충 튜우브의 밀폐 연부를 협착고정시켜서된 수격방지구에 관한 것이다.The present invention relates to the water hammer of the liquid tube, in particular to the water hammer which is fixed between the bent edge of the fixing ring attached to the top of the cylindrical body and the bent edge of the cover plate. It is about.
수격방지구는 송수관이나 송유관등 배관라인의 필요한 부위에 배관과 연통되도록 부착하여 액체가 배관내를 흐를때 관로상의 압력불균일로 인하여 발생하는 수격현상(Water Hammer)을 탄성 매체가 수용된 완층 튜우브에서 흡수, 완화시켜 배관라인의 파손을 방지하고 수격에 의한 소음을 흡수, 방지시키는데 사용한다.Water hammer prevents water hammer from elastic pipe containing elastic medium absorbing water hammer caused by pressure unevenness in pipeline when liquid flows through the pipe. It is used to alleviate the damage of pipe line and to absorb and prevent noise caused by water hammer.
액체관의 수격 방지구는 하단부가 액체관과 연통된 수격방지구 몸체의 내부상측에 고무와 같은 탄성재 완층튜우브를 장착하고 그 튜우브내의 압력공기와 같은 완충매체를 주입 충전하여 튜우브내에 압력매체가 액체관에서 수격방지구 몸체 내부로 유입되어 오는 액체의 수격현상에 대하여 단력적으로 신축 대응되면서 수격 현상을 방지하도록 구성되었다. 종래 수격 방지구는 원통형 몸체의 내부에 탄력성 튜우브를 끼우고 그 이에 덮개판을 씌워 붙여서 튜우브를 장착함에 있어서, 튜우브를 밀폐연부가 끼워지는 몸체의 상측연부와 덮개판의 외연부에 서로 대응되는 플렌지를 형성하고 그들 플렌지에 다수의 볼트 체결공을 뚫어 볼트 너트로서 플렌지를 체결하므로서 튜우브의 밀폐연부가 상하 플렌지 사이에서 긴밀히 가압 밀착되어 튜우브가 밀폐상태로 유지되도록 구성하였다.The water hammer stopper of the liquid pipe is equipped with a rubber-like elastic material complete tube of the lower part of the water hammer stop body in communication with the liquid pipe, and injects and fills a buffer medium such as pressure air in the tube to pressurize the tube. The medium is constructed to prevent the water hammer phenomenon by elastically responding to the water hammer phenomenon of the liquid flowing from the liquid tube into the water hammer body. Conventional water hammer prevents the tubing from the upper edge of the body to which the sealing edge is fitted and the outer edge of the cover plate in fitting the tubing by inserting a flexible tubing inside the cylindrical body and covering the cover plate. The flanges were formed and a plurality of bolt fastening holes were drilled on the flanges to fasten the flanges as bolt nuts, so that the sealing edges of the tubes were closely pressed between the upper and lower flanges so that the tubes were kept in a sealed state.
이와같이 종래의 수격방지구는 몸체와 덮개판에 플렌지를 형성하고 다수의 볼트공을 뚫는 플렌지 가공작업이 번거로울 뿐만아니라 플렌지의 원주면을 따라 여러개의 볼트 너트를 체결하여야 하므로 제작 및 조립비가 많이 소요되고, 더구나 전체 체결볼트의 체결력을 균일하게 유지하지 않으면 어느 일부분에서 액체나 압력기체가 누설되기 쉬워서 소기의 수격방지 기능을 상실하게 되는 결점이 있었다.As described above, the conventional water hammer is not only cumbersome to form a flange on the body and the cover plate, but also requires a lot of bolt processing along the circumferential surface of the flange. In addition, if the tightening force of the entire fastening bolt is not maintained uniformly, liquid or pressure gas is likely to leak in any part, and thus, there is a drawback that the desired water hammering prevention function is lost.
본 고안의 목적은 진술의 종래 결점을 개선하여 완충매체의 누출이 적고 간편하게 제작되는 수격방지구를 제공하는 것이다.It is an object of the present invention to improve the conventional drawbacks of the statement to provide a water hammer which is easy to manufacture with little leakage of the buffer medium.
본 고안은 수격방지구의 몸체와 덮개판의 체결부위에 플렌지를 형성하지 아니하고 그 대신에 절곡연부를 형성하여 몸체와 덮개판의 절곡연부를 서로 절곡부착되도록 형성하므로서 제작과 조립이 용이하고 튜우브의 밀폐연부에 대한 밀착력이 원주면 전체에 걸쳐 균일하여 액체나 압력기체의 누설을 철저히 방지할 수 있도록 형성하므로서 본 고안의 목적이 달성되게 하였다.The present invention does not form a flange on the fastening portion of the body of the water hammer and the cover plate, but instead forms a bent edge to form the bent edge of the body and the cover plate to be bent and attached to each other to facilitate the manufacture and assembly of the tub Adhesion to the sealing edge is uniform across the entire circumferential surface, so that the leakage of liquid or pressure gas is thoroughly prevented, thereby achieving the object of the present invention.
