Yiziphi izimo zokukhetha i-valve butterfly kagesi kanye ne-pneumatic butterfly valve?

Izinzuzo kanye nokusetshenziswa kweama-valve butterfly kagesi

Ugesiuvemvane valveiyithuluzi elivame kakhulu lokulawula ukugeleza kwamapayipi, elinokusetshenziswa okubanzi okuhlukahlukene futhi elibandakanya izinkambu eziningi, njengokulawula ukugeleza kwamanzi edamini lechibi lesikhungo sokuphehla ugesi ngamanzi, ukulawulwa kokugeleza koketshezi lwezimboni embonini, njll. ., futhi okulandelayo kuzokuthatha ukuthi uqonde izici, izinzuzo kanye nokusetshenziswa kwe-valve butterfly kagesi.

1. Ukubekwa uphawu okuhle

Phela indima kagesiuvemvane valveisetshenziselwa ukulungisa ukugeleza koketshezi ngesikhathi, futhi ibhekene nokushisa okuphezulu nokucindezela okukhulu lapho isebenza, ngakho-ke uma ukubekwa uphawu kungalungile, kuzoholela ekuvuzeni kwamanzi, futhi akunakwenzeka ukuqinisekisa ukulungiswa okunembile kokugeleza. . Ugesiuvemvane valveinohlelo olukhethekile lokufaka uphawu, ngakho-ke inokubekwa uphawu okuhle ebangeni lokushisa eliphansi kakhulu kuya ekushiseni okuphezulu, okungukuthi, ukuvalwa kwe-valve uvemvane kagesi akuthintwa izinga lokushisa, futhi ukushintshwa kwe-valve yokulungisa kagesi kulula kakhulu.

2. Ukuvuza okunguziro

Okutuseka kakhulu ukucinana kukagesiuvemvane valve, uphawu lwe-shaft diameter ye-valve stem luthatha indandatho evalwe kakhulu, indandatho yokuvala icindezelwe nge-graphite, indandatho yokuvala kanye nepuleti levemvane le-valve uvemvane kagesi ngeke libambeke, ngakho-ke ukuvala kuhle kakhulu, umlilo ovuzayo awuziro. Ukuphepha kwe-butterfly valve kagesi kuyisinqumo esikhethwa ngamakhasimende amaningi.

3. Ukulungiswa nokulawula okulula

Ugesiuvemvane valveiyithuluzi elisetshenziselwa ukulawula ukugeleza koketshezi, ngaphezu kokuthutha nokulawula uketshezi, udaka nezinye izinto ezine-viscosity ethile nazo zingathuthwa, futhi uketshezi olunqwabelene epayipini luncane, futhi ukuvuleka nokuvala kukagesi kuyashesha. futhi kulula.

Kunezinhlobo eziningi zamavalvu asetshenziswa embonini, kodwa kuthatha umzamo omkhulu ukuthenga i-valve eyanelisa ngempela, ugesi.uvemvane valveinezinhlobonhlobo zezinhlelo zokusebenza, ukusebenza okuqinile nokuvala uphawu okuhle kakhulu, futhi kuwuhlobo lwevalvu kagesi yezimboni esetshenziswa kakhulu.

Izinzuzo kanye nokusetshenziswa kwama-valve butterfly womoya

I-valve ye-butterfly ye-pneumatic yakhiwe i-actuator ye-pneumatic kanye ne-butterfly valve. I-valve uvemvane womoya ivalvu yomoya esebenzisa ipuleti levemvane eliyindilinga elizungeza nesiqu se-valve ukuze livuleke futhi livaleke ukuze kuzuzwe isenzo esivumelayo, esisetshenziswa kakhulu njengevalve yokuvala, futhi ingaklanywa ukuba ibe nomsebenzi wokulungisa noma i-valve yesigaba kanye nokulungisa, kanye ne-valve uvemvane isetshenziswa kakhulu nangokwengeziwe ku-low-pressure enkulu futhi medium-diameter amapayipi. I-pneumatic butterfly valve classification: i-stainless steel pneumatic butterfly valve, i-valve uvemvane womoya oqinile, uphawu oluthambile lwe-butterfly valve, i-carbon steel pneumatic butterfly valve. Izinzuzo eziyinhloko ze-valve uvemvane womoya, isakhiwo esilula, usayizi omncane, isisindo esilula, izindleko eziphansi, i-valve uvemvane womoya ibaluleke kakhulu, efakwe esiteshini esimnyama esisendaweni ephakeme, kulula ukuyisebenzisa ngokulawula i-valve ye-solenoid enezindawo ezimbili, futhi ingalungisa nendawo yokugeleza.

Kunezinye izici ezidinga ukucatshangelwa ohlelweni lwempushana ye-valve butterfly valve, njengokuthi: impahla ayikwazi ukuphuthunyiswa ngokuqondile epuleti le-valve ye-valve lapho ifakwa ku-trolley kusuka phezulu (la mandla omphumela izokwenza futhi i-valve ingakwazi ukuvala ngokuqinile), futhi ingcindezi ye-static yezinto ezibonakalayo akufanele idlule ukucindezela kokuklama kwe-valve butterfly valve, njll.

Umehluko phakathi kwe-valve yokulawula kanye ne-valve evamile ye-manual ukuthi ayikwazi ukubhekwa njengengxenye ehlukile, kodwa kufanele ithathwe njengengxenye yohlelo lonke lokulawula okuzenzakalelayo, izinkinga eziningi ekusetshenzisweni kwe-valve yokulawula akuyona inkinga. yokukhetha nokumisa, kodwa ngenxa yokuthi ukuqonda komsebenzisi kwevalvu yokulawula akwanele, ivalvu yokulawula ayizange ilungiswe futhi ihlanganiswe nohlelo lokulawula. Uma nje siqaphela ukhiye wenkinga, khetha i-valve ngendlela efanele, futhi ulungise i-valve yokulawula esigabeni sokulungisa iphutha, singanciphisa kakhulu izinga lokuhluleka futhi senze uhlelo lokulawula okuzenzakalelayo lusebenze ngokuzinza isikhathi eside.
