REXROTH先導(dǎo)式電磁閥原理,減壓閥工作原理就是通過(guò)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(dòng)保持穩(wěn)定的閥門(mén)。從減壓閥原理和結(jié)構(gòu)來(lái)進(jìn)行區(qū)分的話,目前減壓閥按結(jié)構(gòu)形式分為兩類:
1)比例式減壓閥。采用活塞帶動(dòng)閥瓣運(yùn)動(dòng)的減壓閥,根據(jù)活塞進(jìn)出口有效作用面積比例控制進(jìn)出水壓達(dá)到平衡,同時(shí)達(dá)到定比減壓的目的,產(chǎn)品公稱直徑范圍一般為15mm-150mm。
2)可調(diào)式減壓閥。閥后壓力可調(diào),根據(jù)控制方式又分為:① 直接式:利用彈簧外力和閥門(mén)出口壓力對(duì)薄膜的作用力控制閥瓣開(kāi)度,通過(guò)節(jié)流達(dá)到減壓的目的, 產(chǎn)品公稱直徑范圍一般為15mm~ 150mm。② 先導(dǎo)式:出口壓力的變化經(jīng)先導(dǎo)閥放大控制主閥的開(kāi)度,以達(dá)到減壓的目的,產(chǎn)品公稱直徑范圍一般為50mm-200mm。
