NORGREN電磁提升閥,NORGREN提升閥,NORGREN電磁閥
NORGREN電磁提升閥出廠時(shí)設(shè)置閥芯位置為全開,當(dāng)有壓流體介質(zhì)流經(jīng)閥門后,閥后管道內(nèi)壓力慢慢升高到預(yù)置調(diào)節(jié)壓力值的同時(shí),介質(zhì)通過(guò)預(yù)安裝在調(diào)壓閥膜片或活塞執(zhí)行機(jī)構(gòu)和閥后管道之間連接的引壓銅管(或不銹鋼管)實(shí)現(xiàn)引壓作用,引入介質(zhì)壓力源到閥門執(zhí)行機(jī)構(gòu)內(nèi),使調(diào)壓閥執(zhí)行機(jī)構(gòu)內(nèi)產(chǎn)生相應(yīng)的壓力,然后通過(guò)和執(zhí)行機(jī)構(gòu)連接的閥桿產(chǎn)生推力來(lái)克服閥桿填料摩擦力和調(diào)壓閥彈簧預(yù)緊力以及由介質(zhì)壓力作用在閥芯上而產(chǎn)生的不平衡力,從而使閥芯產(chǎn)生上下直線運(yùn)動(dòng)來(lái)控制閥芯的開度以調(diào)節(jié)改變介質(zhì)壓差和流量,實(shí)現(xiàn)調(diào)壓的目的。當(dāng)閥后介質(zhì)壓力值升高過(guò)設(shè)定調(diào)節(jié)壓力時(shí),執(zhí)行機(jī)構(gòu)產(chǎn)生的下推力增大,閥芯向下直線位移使閥門開度減小,隨之閥后介質(zhì)壓力相應(yīng)下降;當(dāng)閥后介質(zhì)壓力值減小到低于調(diào)壓閥設(shè)定壓力值時(shí),執(zhí)行機(jī)構(gòu)產(chǎn)生的下推力減小,閥芯依靠調(diào)壓閥彈簧預(yù)緊力產(chǎn)生的向上推力,克服執(zhí)行機(jī)構(gòu)產(chǎn)生的下推力和閥桿摩擦力后,使閥芯向上運(yùn)動(dòng),閥門開度增大改變介質(zhì)壓差和流量,使閥后介質(zhì)壓力又向上回升,趨于接近調(diào)壓閥設(shè)定壓力值。這樣周而復(fù)始,循環(huán)動(dòng)態(tài)調(diào)節(jié),使調(diào)壓閥zui終實(shí)現(xiàn)調(diào)壓穩(wěn)壓作用。
