Iivalvu ezininzi eziqhelekileyo ezisetyenziswa kwimibhobho yemizi-mveliso, iivalvu zebhola zezona zisetyenziswa kakhulu, nokuba yimibhobho eqhelekileyo yamanzi, i-oyile negesi okanye iimeko ezirhabaxa zokusebenza eziqulathe amasuntswana anobulukhuni obuphezulu, nokuba bubushushu obuphantsi, ubushushu obuphezulu, okanye indawo eyonakalisayo. , wena Ungasibona isithunzi sevalve yebhola.Njengevalve jikelele esetyenziswa ngokubanzi, kuyimfuneko ukuqonda indlela yofakelo echanekileyo ukuze kusetyenziswe imveliso ngokuchanekileyo nangesayensi (1) Ukulungiswa phambi kofakelo.
①Indlela yokufakela ivalve yebhola Imibhobho engaphambili nangasemva yevalve yebhola sele 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 kokuthambisa ukuze ususe amabala e-oyile, i-welding slag kunye nabo bonke obunye ukungcola kwimibhobho.
③Jonga uphawu lwevalve yebhola ukuze ufumanise ukuba ibhola iphelele.Vula kwaye uvale isithintelo sevalvu amaxesha amaninzi 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 ifakwe kwisiphelo samahhala se-h.Ivalve ye-handle 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.
② Jonga iimfuno zoyilo lombhobho weflange kunye nombhobho wodibaniso lweflange ukufakela iigaskets.
③Iibholithi kwiflange kufuneka zilingane kwaye ziqiniswe enye enye kwaye ngokulinganayo.④Xa udibanisa umbhobho womoya kunye nomqhubi 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.

I-Nortech ngomnye wabavelisi abakhokelayo bevalvu yeshishini e-China kunye nesiqinisekiso somgangatho we-ISO9001.
