I-Petroleum & Petrochemical Check Valve
Izici
Umsebenzi wale valve yokuhlola i-swing ukuvumela i-medium ukuthi igeleze ohlangothini olulodwa kuphela, nokumisa ukugeleza ngakolunye uhlangothi.Ngokuvamile, i-valve isebenza ngokuzenzakalelayo.Ngaphansi kwesenzo somfutho we-fluid ogeleza ohlangothini olulodwa, i-valve clack iyavuleka.Lapho uketshezi lugeleza lubheke kolunye uhlangothi, ithangi elilungisayo lisebenza esihlalweni sokulungisa ngomfutho we-fluid kanye nesisindo se-flap yokulungisa ukusika ukugeleza.
I-valve yokuhlola i-swing ine-hinge mechanism, futhi i-valve efana nomnyango ihlezi ngokukhululekile endaweni yesihlalo se-valve ethambekele.Ukuze uqinisekise ukuthi i-valve flap ingafinyelela endaweni efanele yendawo yokuhlala enetha ngaso sonke isikhathi, i-valve flap yakhelwe kumshini we-hinge, ukuze i-flap yamahhala ibe nesikhala esanele sokushwibeka, futhi i-flap eguquguqukayo ithintana ngokuphelele nesihlalo se-valve. .I-valve ingenziwa ngokuphelele ngensimbi, noma ifakwe ngesikhumba, irabha noma i-synthetic coverage ensimbi, kuye ngezidingo zokusebenza.Lapho i-valve yokuhlola i-swing ivuliwe ngokugcwele, umfutho we-fluid cishe awuphazamiseki, ngakho-ke ukwehla kwengcindezi nge-valve kuncane kakhulu.

Umsebenzi wale valve yokuhlola yokuphakamisa ukuvumela okuphakathi ukuthi kugeleze ohlangothini olulodwa kuphela, nokumisa ukugeleza kolunye uhlangothi.Ngokuvamile, i-valve isebenza ngokuzenzakalelayo.Ngaphansi kwesenzo somfutho we-fluid ogeleza ohlangothini olulodwa, i-valve clack iyavuleka.Lapho uketshezi lugeleza lubheke kolunye uhlangothi, ithangi elilungisayo lisebenza esihlalweni sokulungisa ngomfutho we-fluid kanye nesisindo se-flap yokulungisa ukusika ukugeleza.
Ngaphandle kokuthi i-valve ingavulwa futhi yehliswe ngokukhululekile, yonke enye i-valve iyafana ne-globe valve.Umfutho we-fluid uphakamisa i-clack ye-valve endaweni yokuvala yesihlalo se-valve, futhi isignali yokubuya emaphakathi ibangela iphinikhodi elawulayo ukuthi ibuyele esihlalweni se-valve futhi inqamule ukugeleza.Ngokwezimo zokusetshenziswa, i-shunting ingaba yisakhiwo sonke sensimbi, noma ingaba sesimweni sokufaka amaphedi enjoloba noma izindandatho zenjoloba egameni lohlaka lokudlulisa amagama.Njenge-valve yembulunga, ukudlula koketshezi ngevalve yokuhlola ephakamisayo kuncane, ngakho ukucindezela kwe-valve yokuhlola yokuphakamisa kukhulu kunaleyo yevalve yokuhlola i-swing.
