Abstract
[목적] 적은 파일럿 밸브체의 조작에 의해 대향의 물의 유통 및 그 차단의 제어가 가능한 파일럿 밸브에 있어서, 물에 포함된 이물에 의해 고장을 발생시킬 가능성을 적게하고, 물의 유통을 차단할 때의 워터 헤머의 발생을 방지하도록 한다.[Purpose] A pilot valve capable of controlling the flow of water and the blocking of the opposite water by operating a small pilot valve body, which reduces the possibility of a failure caused by foreign matter contained in the water and cuts off the water flow. Prevent the occurrence of hammers.
[구성] 물의 유통의 차단을 위해 연통공에서 배압실로 물이 유입하는 경우, 배압실에 부설된 중량조절 밸브에서 배압실 내의 물의 일부가 배출된다. 따라서 연통공을 이물에 의한 막힘이 발생하기 어렵도록 크게하여 배압실에의 물의 유입량을 많게 하여도 배압실내의 수량의 증가의 정도를 완속화 할 수 있고, 주밸브체의 동작을 완속화 할 수 있다. 이것에 의해 물의 유통은 천천히 감소하여서 차단되기 때문에, 워터 해머 형상의 발생이 방지된다.[Configuration] When water flows from the communication hole into the back pressure chamber to block the flow of water, part of the water in the back pressure chamber is discharged from the weight control valve installed in the back pressure chamber. Therefore, it is possible to increase the amount of water in the back pressure chamber by slowing down the communication hole so that clogging caused by foreign matters is increased, and to slow down the operation of the main valve body. . As a result, the water flow decreases slowly and is blocked, thereby preventing the occurrence of a water hammer shape.
