之前介紹減壓閥允許壓差的計(jì)算，現(xiàn)在介紹YQ98001過(guò)濾活塞式可調(diào)減壓閥的特點(diǎn)。
YQ98001過(guò)濾活塞式可調(diào)減壓閥的優(yōu)異性能是一種通過(guò)調(diào)節(jié)來(lái)實(shí)現(xiàn)減壓的智能調(diào)節(jié)閥門，可以對(duì)整個(gè)管道的減壓比 例及減壓的長(zhǎng)度進(jìn)行調(diào)節(jié)，可以實(shí)現(xiàn)YQ98009的定比調(diào)節(jié)功能。其在項(xiàng)目當(dāng)中運(yùn)行過(guò)程是：當(dāng)閥門從進(jìn)口端給水時(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)閥彈簧設(shè)定值時(shí)，導(dǎo)閥關(guān)閉?？刂剖彝Ｖ古潘?，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)閥門出口壓力降到導(dǎo)閥彈簧設(shè)定壓力時(shí)，導(dǎo)閥開(kāi)啟，控制室向下游排水。由于導(dǎo)閥系統(tǒng)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。在穩(wěn)定狀態(tài)下，控制室進(jìn)水、排水相同，主閥開(kāi)度不變，出口壓力穩(wěn)定。出口壓力不因進(jìn)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(shè)定值上。該閥減壓，性能穩(wěn)定、安全可靠、安裝調(diào)節(jié)方便，使用壽命長(zhǎng)?？捎糜谏罱o水、 消防系統(tǒng)及工業(yè)給水系統(tǒng)

YQ98001過(guò)濾活塞式可調(diào)減壓閥的優(yōu)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(guò)濾活塞式可調(diào)減壓閥，是一種利用介質(zhì)自身能量來(lái)調(diào)節(jié)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(yíng)閥門有：減壓閥(氣體減壓閥,可調(diào)式減壓閥,水減壓閥當(dāng)閥門從進(jìn)口端給水時(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)閥彈簧設(shè)定值時(shí)，導(dǎo)閥關(guān)閉?？刂剖彝Ｖ古潘藭r(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)閥門出口壓力降到導(dǎo)閥彈簧設(shè)定壓力時(shí)，導(dǎo)閥開(kāi)啟，控制室向下游排水。

由于導(dǎo)閥系統(tǒng)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。在穩(wěn)定狀態(tài)下，控制室進(jìn)水、排水相同，主閥開(kāi)度不變，出口壓力穩(wěn)定。出口壓力不因進(jìn)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(shè)定值上。該閥減壓，性能穩(wěn)定、安全可靠、安裝調(diào)節(jié)方便，使用壽命長(zhǎng)。可用于生活給水、消防系統(tǒng)及工業(yè)給水系統(tǒng)。與本產(chǎn)品相關(guān)論文：小型水電站減壓閥工作原理
