Umehluko phakathi kwe-valve kagesi kanye ne-electromagnetic valve

Ivalvu ye-solenoid iwuhlobo lwevalvu esebenzisa ikhoyili kazibuthe ukuze ilawule ukugeleza koketshezi noma igesi epayipini.Uma ikhoyili kazibuthe ikhanya, ikhipha uzibuthe kumfutho osebenzayo bese iphusha umgogodla wevalvu ibheke endaweni ethile, evumela noma evimbe ukugeleza koketshezi.Lolu hlobo lwevalvu lwaziwa ngokwakheka kwalo okulula nokuthengeka, futhi luvame ukusetshenziswa kumapayipi amancane kuya kwaphakathi nendawo.

Ngakolunye uhlangothi, i-valve yokulawula kagesi iklanyelwe ukulawula okokufaka kwe-analog kokugeleza okuphelele kwezinto ohlelweni lwepayipi yegesi ewuketshezi, futhi ilawulwa ubuhlakani bokwenziwa.Lolu hlobo lwe-valve lungabuye lusetshenziselwe ukusebenza kokushintshwa kwamandla okunezikhundla ezimbili ezinhlelweni zomoya ze-valve zesango elikhulu neliphakathi nendawo.Ivalvu yokulawula kagesi ifakwe isignali yedatha yempendulo ye-AI futhi ingasetshenziswa ngokuphuma kwedijithali (DO) noma okukhiphayo kwe-analog (AO).

I-valve ye-solenoid ingaqedela ukushintshwa kwamandla kuphela, kuyilapho i-valve yokulawula kagesi ingakwazi ukulawula okunembe kakhudlwana ngokusebenzisa ubuchwepheshe obuphambili.Ngaphezu kwalokho, i-valve yokulawula kagesi iyakwazi ukulawula ukugeleza koketshezi kuwo womabili amapayipi amancane namakhulu, kuyilapho i-solenoid valve ngokuvamile isetshenziswa kuphela kumapayipi anobubanzi obuyi-DN50 nangaphansi.

Ngaphezu kwalokho, i-valve elawula i-solenoid ye-fan ifakwe i-valve positioner kagesi, elungiswa ngolawulo lwe-loop evaliwe ukuze yenze i-valve yesango izinze ngendlela enamandla endaweni eyodwa.Lokhu kuqinisekisa ukuthi i-valve ihlala endaweni oyifunayo futhi igcina ukugeleza okuzinzile koketshezi.

Kafushane, ngenkathi womabili amavalvu e-solenoid kanye nama-valve okulawula kagesi esetshenziselwa ukulawula ukugeleza koketshezi noma igesi kumapayipi, i-valve yokulawula kagesi inikeza izici ezithuthuke kakhulu nokulawula okunembile, okuyenza ifanelekele ukusetshenziswa kumapayipi amakhulu kanye nezinhlelo eziyinkimbinkimbi.Ngaleso sikhathi, ama-valve e-solenoid asetshenziswa kakhulu kumapayipi amancane lapho ukufinyeleleka kwawo nokuba lula kunenzuzo.
