The filter piston type adjustable pressure relief valve is an intelligent regulating valve which can realize pressure relief by adjusting. It can adjust the pressure relief ratio and length of the whole pipeline and realize the function of proportional regulation. Its operation process in the project is: when the valve feeds water from the inlet end, water flows through the needle valve into the main valve control room, and the outlet pressure acts on the guide valve through the conduit. When the outlet pressure is higher than the set value of the pilot valve spring, the pilot valve closes. When the control chamber stops draining, the main valve controls the pressure in the chamber to rise and closes the main valve, and the outlet pressure does not rise any more. When the outlet pressure of the valve drops to the set pressure of the guide spring, the guide valve opens and the control chamber drains downstream. The pressure of the main valve control chamber decreases because the drainage of the pilot valve system is larger than that of the needle valve. The inlet pressure opens the main valve. In the stable state, the control room has the same water intake and drainage, the main valve opening remains unchanged, and the outlet pressure is stable. The outlet pressure does not change with the change of the inlet pressure, nor does it change with the change of the outlet flow rate of the main valve. The outlet pressure is maintained at the set value safely and reliably. The valve has the advantages of accurate pressure reduction, stable performance, safety and reliability, convenient installation and adjustment, and long service life. It can be used in domestic water supply, fire fighting system and industrial water supply system.

【進(jìn)口可調(diào)式活塞式減壓閥】工作原理;

當(dāng)管道從進(jìn)水端給水時(shí)，水流過(guò)針閥進(jìn)入主閥控制室，出口壓力通過(guò)導(dǎo)管作用到導(dǎo)閥上，當(dāng)出口壓力高于導(dǎo)閥設(shè)定值時(shí)，導(dǎo)閥關(guān)閉，控制室停止排水，此時(shí)主閥控制室內(nèi)壓力升高并關(guān)閉主閥，出口壓力不再升高。

   當(dāng)出口壓力降到導(dǎo)閥設(shè)定壓力時(shí)導(dǎo)閥開(kāi)啟，控制室向下游排水。由于導(dǎo)閥的排水量大于針閥的進(jìn)水量，主閥控制室壓力下降，進(jìn)口壓力使主閥開(kāi)啟。穩(wěn)定狀態(tài)下，控制室進(jìn)水、排水相同，開(kāi)度不變，出口壓力不變。

   調(diào)節(jié)導(dǎo)閥彈簧即可設(shè)定出口壓力。

1、壓力控制穩(wěn)定可靠。導(dǎo)閥、主閥連續(xù)工作，下游壓力變化連續(xù)、平穩(wěn)，受進(jìn)口壓力影響小。

2、操作方便。工作壓力調(diào)定后，當(dāng)上游壓力或流量變動(dòng)時(shí)主閥自動(dòng)調(diào)節(jié)，穩(wěn)定了下游壓力。

3、閥體采用了全通道、直流式、流線型設(shè)計(jì)。水力損失小，節(jié)能效果好。
