안전밸브의 압력시험 장치{pressure testing apparatus of safety valve}Pressure testing apparatus of safety valve

본 고안은 압력밸브의 안전시험 장치에 관한 것으로서, 특히 정확하고 신속하게 밸브의 결함상태를 테스트할 수 있으며 다양한 크기의 안전밸브를 장착할 수 있도록 한 안전밸브의 압력시험장치에 관한 것이다.The present invention relates to a safety test apparatus for a pressure valve, and more particularly, to a pressure test apparatus for a safety valve that can accurately and quickly test a defect state of a valve and to mount safety valves of various sizes.

일반적으로 안전밸브는 사용하는 기기류에 따라 허용되는 최대압력을 한정하며, 최대압력이 되면 자동적으로 밸브가 열리면서 가스를 방출하여 압력을 감소시킴으로써 설정압력으로 유지될 수 있도록 한다.In general, the safety valve limits the maximum pressure allowed according to the equipment used, and when the maximum pressure is reached, the valve opens automatically, releasing gas to reduce the pressure so that the pressure can be maintained at the set pressure.

이러한 안전밸브들은 신규장착이나 보수 후 조립전에 설정압에서 작동이 되는지 여부를 시험하게 된다.These safety valves are tested for their ability to operate at the set pressure before assembly after retrofitting or maintenance.

통상의 안전밸브 압력시험 장치는 안전밸브 전단의 플랜지에 맞추어 각각의 사이즈별로 단관플랜지를 볼트 및 너트로 체결하여서 질소가스를 주입시킴으로써 압력 시험을 하는 방식이다.Conventional safety valve pressure test apparatus is a pressure test by injecting nitrogen gas by fastening the single pipe flange with bolts and nuts according to the flange of the front end of the safety valve.

그러나 이와 같은 시험장치는 안전밸브의 크기에 따라 다수의 단관플랜지를 준비해야 할 뿐만 아니라 볼트, 너트의 체결 방식에 따른 많은 시간과 노동력이 소요되며, 밸브의 기밀을 유지하기가 어렵다.However, such a test apparatus requires not only a large number of single pipe flanges to be prepared depending on the size of the safety valve, but also requires a lot of time and labor according to the bolt and nut fastening method, and it is difficult to maintain the confidentiality of the valve.

또한, 안전밸브는 대부분 중량물로써 압력시험 장치에 탈, 부착시 어려움이 있으며 설정압력 시험시 질소 가스의 사용량이 많다는 문제점이 있었다.In addition, the safety valve has a problem in that it is difficult to remove and attach to the pressure test apparatus as a heavy material, and the amount of nitrogen gas used during the set pressure test is large.
