GB Cast Steel Globe Valve e nang le Flange e Qetella tšepe e sa hloekang
Tlhaloso ea Tlhahiso
● Lihlahisoa tsa li-valve tsa Globe li entsoe le ho etsoa ho ea ka maemo a naha a GB12235, a nang le mohaho o utloahalang, ho tiisa ka botšepehi, ts'ebetso e babatsehang le ponahalo e ntle.
● The valve disc le valve seat sealing surface li entsoe ka tšepe e entsoeng ka alloy surfacing kapa stellite cobalt-based hard alloy surfacing, e nang le khanyetso e ntle ea ho apara, ho hanyetsa mocheso o phahameng, ho hanyetsa kutu, ho hanyetsa hamonate le bophelo bo bolelele ba tšebeletso.
● Sekhahla sa valve se tima 'me se halefile' me se na le nitrided e ka holimo, e nang le khanyetso e ntle ea ho senya le ho thibela ho halefa.
● Maemo a fapa-fapaneng a liphaephe le liforomo tsa ho tiisa holim'a liphaephe li ka sebelisoa ho fihlela litlhoko tse fapaneng tsa boenjiniere le litlhoko tsa basebelisi.
● The inverted tiiso e entsoe ka khoele khokahanyo tiiso setulo kapa 'mele surfacing ea austenitic tšepe e sa hloekang, e ka tšeptjoang ka ho tiisa, le ho paka ka nkeloa sebaka letsatsi le letsatsi ntle le ho emisa tsamaiso e bonolo le ka potlako ntle le ama tshebetso tsamaiso.
● Khetho ea thepa e ntle haholo, e tsamaellana le litekanyetso tsa lehae le tsa kantle ho naha, 'me boleng ba thepa ka kakaretso bo phahame.
● E finyella litlhoko tsa litekanyetso tse tsoetseng pele lapeng le linaheng tse ling, ka tiiso e ka tšeptjoang, ts'ebetso e babatsehang le ponahalo e ntle.
● Thepa ea ho tiisa e tsoetse pele ebile e utloahala.Likarolo tse tiisitsoeng tsa poleiti ea heke le setulo sa li-valve li entsoe ka li-alloys tse thata tse thehiloeng ho Stellite cobalt tse thata tse fapaneng.Ho tiisoa hoa tšepahala, ho thata haholo, ho hanyetsa ho roala, ho hanyetsa mocheso o phahameng, ho hanyetsa kutu, ho thibela ts'ebetso e ntle ea abrasion le bophelo bo bolelele.
● Sekhahla sa valve se tingoa 'me se halefile' me se na le nitrided e ka holimo, e nang le khanyetso e ntle ea kutu, e thibelang ho senya le ho apara.
● Mohaho oa heke oa rekere oa mofuta oa wedge oa amoheloa, li-diameter tse mahareng le tse kholo li fanoa ka li-thrust bearings, matla a khohlano a nyane, 'me a na le bukana ea tšusumetso, e ka buloang le ho koaloa habonolo.
● Sekala ka botenya.Botenya bo feta 10% botenya ho feta li-valve tsa lefats'e tse tšoanang, 'me bo na le khanyetso e matla ea kutu.
