Iivalvu ezininzi eziqhelekileyo ezisetyenziswa kwimibhobho yoshishino, iivalvu zebhola zinelona luhlu lubanzi lokusetyenziswa, nokuba ngamanzi, i-oyile, igesi okanye imibhobho yemidiya eqhelekileyo okanye iimeko ezirhabaxa zokusebenza eziqulathe amasuntswana anobulukhuni obuphezulu, nokuba bubushushu obuphantsi, ubushushu obuphezulu, okanye i-corrosion. okusingqongileyo, uyakwazi ukubona isithunzi sevalve yebhola.Njengevalve eqhelekileyo esetyenziswa ngokubanzi, kuyimfuneko ukuqonda indlela yofakelo echanekileyo ukuze kusetyenziswe imveliso ngokuchanekileyo nangesayensi (1) Ukulungiselela phambi kofakelo.
①Ivalve yebholaindlela yokufakela Imibhobho yangaphambili nangasemva yevalve yebhola ilungile.Imibhobho yangaphambili nangemuva kufuneka ibe yi-coaxial, kwaye iindawo zokutywinwa kweeflange ezimbini kufuneka zihambelane.Umbhobho kufuneka ukwazi ukumelana nobunzima bevalve yebhola, kungenjalo umbhobho kufuneka uxhotyiswe ngenkxaso efanelekileyo.
②Coca imibhobho ngaphambi nasemva kwesivalo ukususa i-oyile, i-welding slag kunye nabo bonke obunye ukungcola kumbhobho.
③Jonga uphawu lwevalve yebhola ukuze ufumanise ukuba ibhola iphelele.Vula kwaye uvale isiseko sevalve kaninzi ukuqinisekisa ukuba sisebenza kakuhle.
④Susa indawo ekhuselayo kwiflange yokudibanisa yevalve yebhola ekhohlo.
⑤Jonga umngxuma wevalve, susa ubumdaka obunokwenzeka, emva koko ucoce umngxuma.Nokuba izinto ezincinci zangaphandle phakathi kwesitulo sevalve kunye nebhola zingonakalisa umphezulu wokutywina wevalve.
(2) Inkqubo yokufakela
① Fakela ioyile yokuthambisa kumbhobho.Naphi na ekupheleni kwevalve yi-J efakwe kwisiphelo esikhululekileyo se-h.Ivalve ye-lever drive inokufakwa kuyo nayiphi na indawo kumbhobho.Nangona kunjalo, ivalve yebhola yezandla enebhokisi yegiya kunye nevalve yebhola yepneumatic enomqhubi wepneumatic zifakwe zime nkqo, oko kukuthi, zifakwe kumbhobho othe tye, kwaye isixhobo sokuqhuba siphezu kombhobho.
②Uyilo lweflange yevalvu kunye neflange yombhobho kufuna ukufakelwa kwegasket.
③Iibholithi kwiflange kufuneka zilingane kwaye ziqiniswe enye enye kwaye ngokulinganayo.④Qhagamshela umbhobho womoya 'xa kusetyenziswa umqhubi we-pneumatic).
(3) Ukuhlolwa emva kokufakwa
① Sebenzisa umqhubi ukuvula nokuvala ivalve yebhola amaxesha amaninzi.Kufuneka ibe bhetyebhetye kwaye ingabi nanzondo ukuze iqinisekise ukuba isebenza ngokufanelekileyo.②Uyilo lombhobho woqhagamshelo lufuna ukuhlolwa kokutywinwa kokusebenza komphezulu odityanisiweyo weflange wombhobho kunye nebhola.
