Ivalvu Ye-Butterfly Ephindwe Kabili vs Ivalvu Ye-Butterfly Ephindwe Kathathu？

Uyini umehluko phakathi kwevalvu yebhabhathane ephindwe kabili nevalvu yebhabhathane ephindwe kathathu?

Kuma-valve ezimboni, ama-valve e-butterfly aphindwe kabili kanye nama-valve e-butterfly aphindwe kathathu angasetshenziswa ekuphatheni uwoyela negesi, amakhemikhali kanye namanzi, kodwa kungaba nomehluko omkhulu phakathi kwalezi zinhlobo ezimbili zama-valve e-butterfly, ngakho-ke kubalulekile ukwazi umehluko phakathi kwalezi zinhlobo ezimbili zama-valve ukuze wenze ukukhetha okufanele.

Kulesi sihloko, sizobheka umehluko omkhulu phakathiamavalvu ebhabhathane aphindwe kabilifuthiamavalvu ebhabhathane aphindwe kathathukanye nezinzuzo zazo kanye nezicelo zazo.

Okokuqala, ukwakheka nokwakhiwa kuhlukile.

Idiski yeivalvu yebhabhathane ephindwe kabiliisuselwe emugqeni ophakathi womzimba wevalvu kanye nomgodi. Lo mklamo we-offset usiza ukungqubuzana nokuguguleka kwesihlalo sevalvu esithambile ngesikhathi sokuvula nokuvala, ngaleyo ndlela kwandise impilo yesevisi futhi kuthuthukiswe ukuvalwa. Ngenkathi ivalvu yebhabhathane ebizwa ngokuthi i-triple eccentric ine-eccentric yesithathu phezu kwe-eccentric eccentric ephindwe kabili, okungukuthi, yakha isimo esiyindilinga ebusweni bokuvala, futhi izinto zobuso bokuvala zivame ukuvalwa ngensimbi, okuholela ekuvalekeni okuqinile kanye nokungqubuzana okuncane, okwenza kube kuhle kakhulu ekusetshenzisweni kokucindezela okuphezulu kanye nokushisa okuphezulu.

Okwesibili, ukusebenza kuhlukile.

Amavalvu ebhabhathane aphindwe kathathuinikeza izinzuzo eziningana kunemiklamo emibili engavamile. Idizayini engavamile kathathu inikeza ukuvala okungenamoya, okusho ukuthi ukuvuza kungavinjelwa ngempumelelo ngisho nangaphansi kwengcindezi ephezulu kanye nezimo zokushisa okuphezulu. Ngakho-ke ifaneleka kakhulu kwizicelo ezibalulekile ezidinga ukuvalwa okuqinile. Ngaphezu kwalokho, umklamo wesembozo sekhoni se-valve ye-butterfly engavamile kathathu uthuthukisa ukumelana nokuguguleka ukuze izikhawu zokulungisa zandiswe futhi izindleko zokulungisa zincishiswe. Lezi zinzuzo zokusebenza zenza i-valve ye-butterfly engavamile kathathu ibe yisinqumo sokuqala sezicelo ezidingakalayo embonini kawoyela negesi, i-petrochemical kanye nokukhiqizwa kukagesi.

Ekugcineni,Izindleko zokwakha azisetshenziswa.

Inzuzo enkulu kakhuluivalvu yebhabhathane ephindwe kabiliUma kuqhathaniswa ne-valve ye-butterfly eccentric kathathu, izindleko zokwakha ziphansi kancane. Uma izimo zokusebenza zingadingi izinga lokushisa eliphezulu kanye ne-valve ye-butterfly eccentric kathathu eccentric ephezulu, i-valve ye-butterfly eccentric ephindwe kabili iyindlela engabizi kakhulu. Lokhu kungenxa yokuthi ama-valve e-butterfly eccentric amabili afaneleka ukusetshenziswa okubandakanya ukucindezeleka okuphansi kuya kokuphakathi kanye namazinga okushisa. Ukusebenza kwawo okuthembekile kanye nokusebenza kahle kwezindleko kuwenza abe ukukhetha okuthandwayo kwezinhlobo ezahlukene zezicelo zezimboni.

Ekuphetheni, ukukhetha phakathi kokuphindwe kabili kanyeamavalvu ebhabhathane angavamile kathathukuncike ezidingweni ezithile zendlela kanye nendawo ezungezile. Amavalvu ebhabhathane aqinile amathathu afanelekela izimo ezidinga ukuvalwa okuphezulu kanye nokumelana nokucindezela okuphezulu kanye namazinga okushisa, kuyilapho amavalvu aqinile aphindwe kabili enikeza ikhambi elingabizi kakhulu lezinhlelo zokusebenza ezingabizi kakhulu.
