I-valve yebhola yomoya enezigaba ezimbili

I-valve yebhola yomoya enezigaba ezimbili isetshenziswa kakhulu ekulawuleni okuzenzakalelayo ezinhlelweni zokulayisha nokukhipha impahla, futhi ifanelekela izimo zokusetshenziswa lapho kunezidingo ezicacile zenqubo yokuvula nokuvala kanye nesimo sokuphepha. Ngokusebenzisa umqondo wesenzo esinezigaba ezimbili, i-valve ifinyelela ukulawula kokuvula nokuvala okuhleliwe, okusiza ukuthuthukisa ukuphepha nokulawulwa kwenqubo yokusebenza kokulayisha nokukhipha impahla.

I-actuator ye-valve ingasebenzisa i-actuator ye-pneumatic enezikhundla ezintathu noma ilawulwe yisesekeli sikagesi esilawula ukwahlukana. Ngesikhathi sokusebenza, i-valve ingaqedela ukuvulwa kokuqala kanye nokuvulwa okugcwele ngokulandelana okubekiwe, noma ivale ngokulandelana okuphambene, okusetshenziselwa ukunciphisa umthelela osheshayo we-medium nokunciphisa umthwalo kumapayipi kanye nemishini ehlobene nawo, efanelekile ezimweni zokulayisha nokukhulula uketshezi noma igesi.

Isimo sephutha levalvu ngokuvamile sisethwa njengesivaliwe. Uma kwenzeka ukunikezwa komoya okungajwayelekile noma isignali yokulawula, ivalvu ingavala ngokuzenzakalelayo ukuvimbela ukuvuza okuphakathi futhi ihlangabezane nezidingo zokuphepha ngesikhathi sokulayisha nokukhipha impahla. Ivalvu isekela ukusebenza kwendawo kanye nokulawula okude, futhi ingalungiswa ngamaswishi okuhamba, amasignali okukhiya, kanye namamojula okuxhumana, okwenza kube lula ukuxhuma ezinhlelweni ze-DCS noma ze-PLC zokuqapha isimo kanye nokuphathwa okuphakathi.

Isikhathi sokusebenza kwevalvu singakhethwa futhi silungiswe ngokwezimo zokusebenza zangempela, ezingahlangabezana nezidingo zokusebenza kahle kokulayisha nokukhipha impahla futhi zicabangele nokuzinza kokusebenza kwesistimu. Uma isetshenziswa njengevalvu yokuzilawula yokulayisha nokukhipha impahla, ivalvu yebhola yomoya enezigaba ezimbili ingaqinisekisa ukuphepha kokusebenza ngenkathi ithuthukisa ukuthembeka nokuguquguquka kokulawula endaweni.
