Iyini i-SDV Valve?

Amavalvu e-SDVuhlobo lwemishini yokuphepha evame ukusetshenziswa embonini ye-petrochemical, yezemithi, yokudla kanye neminye imboni kanye namapulatifomu kawoyela asogwini, igama eliphelele lithiivalvu yokuvala, kanti igama lesiShayina lithi cut off Valve noma Shut off valve. Okulandelayo isingeniso esiningiliziwe se-SDV valve:

Ukwakheka kanye nesakhiwo sama-SDV Valve

Ivalvu ye-SDV yakhiwe kakhulu ngezingxenye ezimbili: i-actuator kanye nomzimba wevalvu. I-actuator ihlanganisa i-piston, isipilingi kanye nesandla, kanye nengxenye yokushintsha okuzenzakalelayo. Iyi-actuator yomoya yohlobo lokuvula umoya, futhi ifakwe ivalvu ye-solenoid ukuvula noma ukuvala indlela yegesi, esetshenziselwa ukulawula ukuvulwa noma ukuvalwa kwevalvu.

Umgomo wokusebenza we-valve ye-SDV

Isimiso sokusebenza sevalvu ye-SDV sisekelwe ku-actuator yomoya. Ngemva kokuthola imiyalelo yesistimu ye-FSC noma uhlelo lokuvala oluphuthumayo (i-ESDV), ivalvu ivulwa noma ivalwe ngokuzenzakalelayo ngokulawula ukuvulwa komthombo womoya ocindezelwe ngevalvu ye-solenoid.

Umsebenzi kanye nokusetshenziswa kwama-SDV Valve

I-valve ye-SDV idlala indima yokuvikela ukuvalwa okuphuthumayo ohlelweni, futhi ngokuvamile itholakala epayipini lokuphuma lemishini. Uma kwenzeka izimo ezingavamile, inganqamula ngokushesha iluphu yomthombo womoya ukuvimbela ukuthi i-medium ingaqhubeki nokugeleza, ngaleyo ndlela iqinisekise ukuphepha kohlelo.

Ama-valve e-SDV asetshenziswa kabanzi kumapulatifomu kawoyela asogwini kanye nasembonini yamakhemikhali kaphethiloli asogwini. Kumapulatifomu kawoyela asogwini, ama-valve amakhulu e-SDV (isb., usayizi wama-valve ≥16 amayintshi, isigaba samaphawundi ≥900LB) avame ukutholakala ekuphumeni kwesiqalisi sebhola lengulube noma emnyango wesamukeli sebhola lengulube, futhi ayimishini yokuphepha ebalulekile kule nqubo.

Izici nezinzuzo

I-valve ye-SDV inezici zokugcinwa okuphephile, okuthembekile nokulula kwe-actuator yomoya, efanelekile ikakhulukazi ezindaweni eziyingozi.

Amavalvu e-SDV avuleka ngokuphelele futhi avalwe ngokuphelele, ngakho-ke aziwa nangokuthi amavalvu anezindawo ezimbili. Lo mklamo wenza amavalvu e-SDV asebenze kahle lapho ukugeleza okuphakathi kudinga ukunqunywa ngokushesha nangokunembile.

Ku-Summery

Ama-valve e-SDViyithuluzi lokuphepha elibalulekile elidlala indima ebalulekile embonini ye-petrochemical, yezemithi, yokudla kanye neminye, kanye nasezinkundleni zikawoyela zasogwini. Ifeza umsebenzi wokuvula noma wokuvala okuzenzakalelayo nge-actuator yomoya, inezici zokuphepha, ukuthembeka, ukulungiswa okulula, futhi inganqamula ngokushesha ukuhamba okuphakathi esimweni esiphuthumayo ukuqinisekisa ukuphepha kohlelo.
