之前介紹減壓閥允許壓差的計算，現在介紹YQ98001過濾活塞式可調減壓閥的特點。
YQ98001過濾活塞式可調減壓閥的優異性能是一種通過調節來實現減壓的智能調節閥門，可以對整個管道的減壓比 例及減壓的長度進行調節，可以實現YQ98009的定比調節功能。其在項目當中運行過程是：當閥門從進口端給水時，水流過針閥進入主閥控制室，出口壓力通 過導管作用到導閥上。當出口壓力高于導閥彈簧設定值時，導閥關閉。控制室停止排水，此時主閥控制 室內壓力升高并關閉主閥，出口壓力不再升高。當閥門出口壓力降到導閥彈簧設定壓力時，導閥開啟，控制室向下游排水。由于導閥系統排水量大于針閥的 進水量，主閥控制室壓力下降。進口壓力使主閥開啟。在穩定狀態下，控制室進水、排水相同，主閥開度不變，出口壓力穩定。出口壓力不因進口壓力變化而改變， 亦不因主閥出口流量的變化而改變，安全可靠地將出口壓力維持在設定值上。該閥減壓，性能穩定、安全可靠、安裝調節方便，使用壽命長。可用于生活給水、 消防系統及工業給水系統

YQ98001過濾活塞式可調減壓閥的優異性能譯文：
Adjustable YQ98001 filter piston type pressure reducing valve, it is based on a medium energy inligent valve to regulate and control line pressure. When the valve from the inlet water supply, water flows through a needle into the main valve control room, outlet pressure through the catheter to the pilot valve. When the outlet pressure is higher than the pilot valve spring set value, pilot valve to close. Control room to stop drainage, at this time the main valve to control the indoor pressure and close the main valve, outlet pressure is no longer increases. When the valve outlet pressure down to guide valve spring set pressure, the pilot valve open, the control room to the downstream drainage. Because the pilot valve system of displacement is greater than the needle valve into the water, the main valve control room pressure drop. Open the main valve inlet pressure. Under steady state, the control room the same feed water and drainage, the main valve opening is changeless, outlet pressure stability. Inlet pressure, outlet pressure has no change and change, nor because of the change of the main valve outlet flow change, safe and reliable to keep outlet pressure on the set value. The valve decompression precision, stable performance, safe and reliable, easy installation and adjustment, long service life. Can be used for drinking water and industrial water supply system, fire control system.YQ98001

 YQ98001過濾活塞式可調減壓閥，是一種利用介質自身能量來調節與控制管路壓力的智能型閥門。上海申弘閥門有限公司主營閥門有：減壓閥(氣體減壓閥,可調式減壓閥,水減壓閥當閥門從進口端給水時，水流過針閥進入主閥控制室，出口壓力通過導管作用到導閥上。當出口壓力高于導閥彈簧設定值時，導閥關閉。控制室停止排水，此時主閥控制室內壓力升高并關閉主閥，出口壓力不再升高。當閥門出口壓力降到導閥彈簧設定壓力時，導閥開啟，控制室向下游排水。

由于導閥系統排水量大于針閥的進水量，主閥控制室壓力下降。進口壓力使主閥開啟。在穩定狀態下，控制室進水、排水相同，主閥開度不變，出口壓力穩定。出口壓力不因進口壓力變化而改變，亦不因主閥出口流量的變化而改變，安全可靠地將出口壓力維持在設定值上。該閥減壓，性能穩定、安全可靠、安裝調節方便，使用壽命長。可用于生活給水、消防系統及工業給水系統。與本產品相關論文：小型水電站減壓閥工作原理
