進(jìn)口活塞式減壓閥概述
進(jìn)口活塞式減壓閥是指采用活塞作為閥瓣,通過調(diào)節(jié),將進(jìn)口壓力減至某一需要的出口壓力,并依靠介質(zhì)本身的能量,使出口壓力自動保持穩(wěn)定的減壓閥。

The piston valve refers to the use of the piston as a valve, by adjusting the inlet pressure is reduced to a desired outlet pressure, and rely on the energy of the medium itself automatically to maintain the stability of the pressure reducing valve, so that the outlet pressure.
主要分為進(jìn)口彈簧活塞式減壓閥和進(jìn)口膜片活塞式減壓閥,可用于蒸汽、水、氣體,主要產(chǎn)品進(jìn)口膜片活塞式減壓閥、進(jìn)口彈簧活塞式減壓閥,進(jìn)口先導(dǎo)活塞式氣體減壓閥。
用途和主要性能:本閥適用于水、蒸汽、空氣介質(zhì)管路上,通過調(diào)節(jié)使進(jìn)口壓力降低至某一需要的出口壓力,當(dāng)進(jìn)口壓力與流量有變化時,靠介質(zhì)本身的能量自動保持出口壓力在一定范圍內(nèi),但進(jìn)口壓力和出口壓力之差必須≥0.2MPA/CM
工作原理及結(jié)構(gòu):減壓閥出廠時,調(diào)節(jié)彈簧處于未壓縮狀態(tài),此時主閥瓣和付閥瓣處于關(guān)閉狀態(tài),使用時按順時針轉(zhuǎn)動調(diào)節(jié)螺釘,壓縮調(diào)節(jié)彈簧,使膜瓣移頂開付閥瓣,介質(zhì)由a孔通過付閥座到b孔進(jìn)入活塞上方,活塞在介質(zhì)壓力的作用下,向下移動推動主閥瓣離開主閥座,使介質(zhì)流向閥后.同時由c孔進(jìn)入膜片下方,當(dāng)閥后壓力超過調(diào)定壓力時,推動膜片上移壓縮調(diào)節(jié)彈簧,付閥瓣隨之向關(guān)閉方向移動,使流入活塞上方的介質(zhì)減小,壓力也隨之下降,此時的主閥瓣在主閥瓣彈簧力的推動上下移,使主閥瓣與主閥座的間隙減小,介質(zhì)流量也隨之減小,使閥后壓力也隨之下降到新的平衡,反之當(dāng)閥后壓力低于調(diào)定壓力時,主閥瓣與主閥座的間隙增大,介質(zhì)流量也隨之增加,使閥后壓力也隨之增高達(dá)到新的平衡.
