I-Double Offset Butterfly Valve vs Triple Offset Butterfly Valve?

yini umehluko phakathi kwe-double eccentric kanye ne-triple eccentric butterfly valve?

Kuma-valve ezimbonini, ama-valve evemvane ane-eccentric kabili kanye nama-valve butterfly eccentric kathathu angasetshenziswa kuwoyela negesi, ekwelapheni amakhemikhali namanzi, kodwa kungaba khona umehluko omkhulu phakathi kwalezi zinhlobo ezimbili zamavalve ovemvane, ngakho-ke kubalulekile ukwazi umehluko. phakathi kwalezi zinhlobo ezimbili zama-valve ukuze wenze ukukhetha okufanele.

Kulesi sihloko, sizobheka umehluko omkhulu phakathidouble offset butterfly valvesfuthitriple offset butterfly valveskanye nezinzuzo kanye nokusetshenziswa kwazo.

Okokuqala, ukuklama nokwakhiwa kuhlukile.

I-disc yei-valve ye-butterfly ephindwe kabiliisuswa kusukela kumugqa omaphakathi womzimba we-valve kanye ne-shaft.Lo mklamo we-offset usiza ukungqubuzana nokuguga kwesihlalo sevalvu ethambile ngesikhathi sokuvula nokuvala, ngaleyo ndlela andise impilo yesevisi futhi kuthuthukiswe ukuvala.Nakuba okuthiwa i-valve butterfly eccentric ephindwe kathathu ine-eccentric yesithathu phezu kwe-eccentric ephindwe kabili, okungukuthi, yakha isimo se-conical endaweni yokuvala, futhi impahla yendawo yokuvala kuvame ukuvala uphawu lwensimbi, okuholela ekuvaleni okuqinile nokuqina. ukungqubuzana okuncane, okuyenza ilungele izinhlelo zokusebenza ezinomfutho ophezulu kanye nezinga lokushisa eliphezulu.

Okwesibili, ukusebenza kuhlukile.

Ama-valve evemvane e-eccentric kathathuukunikeza izinzuzo eziningana phezu imiklamo eccentric kabili.Umklamo we-eccentric kathathu unikeza uphawu oluqinile lomoya, okusho ukuthi ukuvuza kungavinjelwa ngokuphumelelayo ngisho nangaphansi kwengcindezi ephezulu kanye nezimo zokushisa eziphezulu.Ngakho-ke ifaneleka kakhulu izinhlelo zokusebenza ezibucayi ezidinga ukuvalwa okuqinile.Ngaphezu kwalokho, idizayini yekhava ye-valve uvemvane kathathu ithuthukisa ukumelana nokuguga ukuze izikhawu zokulungisa zinwetshwe futhi nezindleko zokuyilungisa zehliswe.Lezi zinzuzo zokusebenza zenza i-valve ye-butterfly eyi-triple eccentric ibe yinketho yokuqala ekusetshenzisweni okufunwa kakhulu embonini kawoyela negesi, i-petrochemical kanye nezimboni zokuphehla amandla.

Ekugcineni, i-the izindleko zokwakha azisetshenziswa.

Inzuzo enkulu yei-valve ye-butterfly ephindwe kabiliuma kuqhathaniswa ne-valve butterfly eccentric kathathu ukuthi izindleko zokwakha ziphansi kancane.Uma izimo zokusebenza zingadingi izinga lokushisa eliphezulu kanye ne-high pressure triple eccentric butterfly valve, i-valve uvemvane ene-eccentric ephindwe kabili iwukukhetha ukonga kakhulu.Lokhu kungenxa yokuthi ama-valve uvemvane ane-eccentric ephindwe kabili afanele izinhlelo zokusebenza ezifaka izingcindezi eziphansi kuya eziphakathi nendawo namazinga okushisa.Ukusebenza kwabo okuthembekile nokusebenza kahle kwezindleko kubenza babe ukukhetha okudumile kwezinhlelo zokusebenza ezihlukene zezimboni.

Ekugcineni, ukukhetha phakathi kokuphindwe kabili kanyeama-valve evemvane eccentric kathathukuncike ezidingweni ezithile zendawo nendawo ezungezile.Ama-valve evemvane e-eccentric kathathu afanele izimo ezidinga ukuvalwa okuphezulu kanye nokumelana nezingcindezi eziphezulu namazinga okushisa, kuyilapho ama-valve e-eccentric ephindwe kabili enikeza isixazululo esingabizi kakhulu sezinhlelo zokusebenza ezingadingi kakhulu.
