Yiziphi izimo ezifanele ama-valve okuhlola?

Njengesisetshenziswa esibalulekile sokuvimbela ukubuyela emuva okumaphakathi,hlola ama-valveasetshenziswa kakhulu emikhakheni yezimboni, yezakhamuzi, nekhethekile. Umsebenzi wabo oyinhloko ukuvikela ukuphepha kwemishini, ukugcina ukuqina kwesistimu, nokugwema izingozi. Emkhakheni wezimboni, ama-valve okuhlola angavimbela ukubuyela emuva kwemidiya ephezulu yokushisa kanye ne-high-pressure kumapayipi kawoyela negesi, ukuvimbela ingozi yokuqhuma okubangelwa ukungalingani kwengcindezi yamapayipi; Ekukhiqizweni kwamakhemikhali, ingavimbela ukuphindaphindeka koketshezi olubolayo noma olune-viscosity ephezulu, igweme ukugqwala kwemishini noma ukuvaleka. Isibonelo, ukufaka ama-valve okuhlola endaweni yokungena nokuphuma kwe-reactor kungavimbela ukuguquguquka kwengcindezi ekubangeleni ukugeleza okubuyela emuva kwe-medium, kuqinisekiswe izimo zokusabela ezinzile; Isistimu yamanzi okuphakelayo kubhayela embonini yamandla incike kuma-valve okuhlola ukuvimbela isenzakalo sesando samanzi. Uma amanzi egeleza abuye lapho iphampu yamanzi imisiwe, izoba nomthelela ku-impeller futhi kulimaze nomzimba wepompo.Hlola ama-valveingaqinisekisa ukugeleza kwamanzi ngendlela eyodwa futhi iqinisekise ukusebenza okuqhubekayo kwesistimu.

Ezimweni ezingavamile,cama-valve adingekayo kumanethiwekhi okuhambisa amanzi okwakha asezingeni eliphezulu ukuvimbela isando samanzi. Lapho iphampu lamanzi lima kungazelelwe, inertia yokugeleza kwamanzi izodala ukushaqeka komfutho, kulimaze ipayipi namavalvu. Ama-valve okuhlola angavimba ngokushesha ukugeleza emuva futhi asuse ingozi efihliwe yesando samanzi; Ukufaka ama-valve okuhlola ezinhlelweni zamanzi zasendlini kungavimbela indle ukuthi ingangcolisi amanzi ahlanzekile. Isibonelo, ukufaka ama-valve okuhlola lapho kuphuma izifudumezi zamanzi elanga kungavimbela amanzi ashisayo ukuthi angabuyeli epayipini lamanzi abandayo, kuqinisekise ukuphepha kwamanzi.

Ngokwezinjongo ezikhethekile, okokusebenza kokukhipha usawoti emanzini olwandle kusebenzisa ama-valve okuhlola ukuvimbela ukubuya kwamanzi olwandle nokuvikela okokusebenza ekugqwaleni; Ukufaka i-valve yokuhlola lapho kuphuma khona i-compressor yomoya kungavimbela umoya ocindezelwe ukuba ungabuyeli emuva futhi kubangele ukuba i-compressor ihlehle, ngaleyo ndlela ithuthukise ukusebenza kahle kohlelo; Ivalvu yokuhlola ifakwe lapho kuphuma khona indawo yokumpompa amapayipi amanzi ahamba ibanga elide ukuze kuvinjwe imithombo yezindaba engaphansi komfula ukuthi ingagelezi ibuyele esiteshini sokumpompa esikhuphuka nomfula, kuqinisekiswe ukuqhubeka kokuhamba; Ipayipi lesistimu yesitimu lincike kumavalvu okuhlola ukuvimbela ukuminyana noma ukugeleza kwesitimu emuva, ukunciphisa ubungozi besando samanzi, nokugcina ikhwalithi yesitimu.
