Uyini umgomo wokubopha we-valve yesithathu ye-eccentric?

Umgomo wokubopha we-eccentric amathathuI-I-I-I-butterfly valveKususelwa kumklamo wesakhiwo sayo esiyingqayizivele esijwayelekile, esakha indawo yokubopha uphawu le-elliptical ngokusebenzisa uphawu lwe-torque lwe-valve lwensimbi oluqinile lwe-hardvel valve futhi ngokuyisisekelo ukuxazulula ukulimala kwezinkinga zendabuko.

Ngokuqondile, umgomo wokubopha we-eccentric amathathuI-I-I-I-butterfly valveKubandakanya amaphuzu alandelayo aphambili:

Isakhiwo se-eccentric esishisiwe Lo mklamo uqinisekisa ukuthi akukho ngxabano phakathi kwepuleti ye-valve kanye nesihlalo se-valve ngesikhathi senqubo yokuvula nokuvala ye-valve yevemvane, ukuthuthukisa kakhulu impilo ye-valve.

I-Torque Searing Mechanism: Ukubekwa uphawu kwe-valve e-eccentric butterfly ezintathu akusekho ukubeka uphawu kwesikhundla, kepha uphawu lwe-torque. Lapho i-butterfly valve ivaliwe, ingcindezi yokubopha uphawu phakathi kwalezi zindawo ezimbili zokubekwa uphawu kwayo ukubopha uphawu kwayo kukhiqizwa i-torque yokushayela isetshenziswe esiqwini se-valve. Le ndlela yokuvalwa isinxephezela ngempumelelo indawo yokubekezelela phakathi komkhono we-shaft kanye nomzimba we-valve, kanye nokuguquguquka okunwebekile kwesiqu se-valve ngaphansi kwengcindezi ephakathi, ukuxazulula ukubekwa uphawu okukhona ekushintsheni okuhlobene nama-valves.

Ukuxhumana okungelonakaliswa kobuso bendawoI-I-I-I-butterfly valveIsakhiwo se-cone esishisiwe, kanye nokwakheka kwe-valve Plate Balling Surface yi-Asymmetric kusuka phezulu kuya phansi. Lapho kuvulwa i-butterfly valve kusuka ku-0 ° kuya ku-90 °, ingaphezulu lokubekwa uphawu lepuleti le-valve lizovela endaweni yokubopha yesihlalo se-valve ngesikhathi sokuvula; Lapho ivaliwe kusuka ku-90 ° kuya ku-0 °, okwamanje, indawo yokuvalwa kwepuleti ye-valve izothintana futhi icindezele indawo yokubopha yesihlalo se-valve. Lo mklamo awuhambelani nengxabano phakathi kwesihlalo se-valve kanye nendawo yokubopha uphawu epuletini uvemvane, kuqeda amathuba okugqoka nokuvuza.

Ukusebenza kokubekwa uphawu okuguqukayo: Isilinganiso se-Seaning Pressure Surve ye-Eccentric Butterfly Valve singashintshwa ngokunqumela ngokushintsha i-torque yangaphandle, ngaleyo ndlela sithuthukise ukusebenza kokubekwa uphawu kwe-eccentric butterfly ye-eccentric futhi kwandise kakhulu impilo yayo yenkonzo.
