I uvemvane olujiyile ngogesi I-valve yakhiwe ngomzimba we-valve, ipuleti le-butterfly, indandatho yokuvala, indlela yokudlulisa kanye nezinye izingxenye eziyinhloko. Isakhiwo sayo sisebenzisa ukwakheka kwesimiso se-eccentric esinezinhlangothi ezintathu, uphawu lwe-elastic kanye nobuchwepheshe bokucubungula obuhambisana nophawu oluqinile noluthambile olunezingqimba eziningi, ukuze i-valve ye-butterfly isebenze, inciphise amandla ayo e-torque, ukuze kufezwe ukonga abasebenzi, imisebenzi yokonga amandla. Ngakho-ke kuqinisekisa ukumelana nokugqwala okuphelele. Ukumelana nokushisa okuphezulu. , ukuthembeka kokulwa nokubola. Ngokusekelwe ekusungulweni kobuchwepheshe obuthuthukisiwe bangaphandle, lo mkhiqizo usebenzisa indandatho yokuvala elastic enobunjwa obungu-J kanye nesakhiwo sensimbi eqinile enezingqimba ezintathu, esetshenziswa kabanzi ekushiseni okuphakathi ≤425℃ igolide, amandla kagesi, imboni ye-petrochemical, ukuhlinzekwa kwamanzi kanye nokugeleza kwamanzi kanye nokwakhiwa komasipala kanye neminye imipayipi yezimboni yokulawula ukugeleza nokuthwala umzimba wamanje.
Ivalvu isebenzisa isakhiwo esingavamile esithathu, isihlalo sevalvu kanye nobuso bokuvala ipuleti kwenziwa ngobunzima obuhlukene kanye nensimbi engagqwali, ngokumelana okuhle nokugqwala, impilo ende yenkonzo, umsebenzi wokuvala ivalvu yezempi, umkhiqizo uhambisana nezinga lokuhlolwa kwengcindezi yevalvu ye-**GB/T13927-92. Ivalvu isebenzisa isakhiwo sokuvala esingavamile esithathu, isihlalo sevalvu kanye nepuleti lebhabhathane cishe akukho ukugqwala, ngomsebenzi wokuvala oqinile kakhulu; Indandatho yokuvala yenziwe ngensimbi engagqwali, enezinzuzo ezimbili zensimbi eqinile kanye nokuvalwa okunwebekayo, kungakhathaliseki ukuthi izinga lokushisa liphansi kanye nokushisa okuphezulu, inokusebenza okuhle kakhulu kokuvala, ukumelana nokugqwala, impilo ende yenkonzo kanye nezinye izici; Ubuso bokuvala ipuleti bune-carbide eqinisiwe esekelwe ku-cobalt, engagugi futhi enempilo ende yenkonzo. Ipuleti elikhulu lisebenzisa isakhiwo sohlaka oluhlanganisiwe, amandla aphezulu, indawo enkulu yokugeleza kanye nokumelana okuncane kokugeleza; Ivalvu inomsebenzi wokuvala ohlangothini lwesibili, ukufakwa akukhawulelwe yisiqondiso sokugeleza kwe-medium, futhi akuthinteki yisikhundla sendawo, kungafakwa kunoma iyiphi indlela; Iyunithi yokushayela ingafakwa eziteshini eziningi (ukujikeleza okungu-90° noma okungu-180°) ukuze kube lula ukuyisebenzisa.
Izici zokusebenza eziyinhloko
Ukusebenza okuncane nokulula, okuguquguqukayo, okonga abasebenzi, okulula;
Ukuvalwa okuthembekile, kungafinyelela ukuvalwa kwegesi ngaphandle kokuvuza;
Isimiso esinezici ezintathu siyasetshenziswa ukwenza indawo yokuvala ilingane nokulahlekelwa yilutho futhi sandise impilo yesevisi yevalvu.
Uhlu olubanzi lwezicelo. Njenge: ingasetshenziswa emanzini, umusi, uwoyela, umoya, igesi kanye nezinye izinto.
Isebenza emazingeni okushisa ahlukene kanye namazinga okucindezela angaphansi kuka-6.4MPa, ukumelana nokugqwala kanye neminye imipayipi ephakathi nendawo
