American Standard WeldingPlug ValveTlhaloso e Khutšoanyane:
Valve ea plug e na le sebopeho se bonolo, phetoho e potlakileng, ho hanyetsa mokelikeli o monyane, le ts'ebetso ea stroke e potlakileng ea angular.Boemong ba tšohanyetso bo kang kotsi, phaephe e ka kopanngoa kapele kapa ea khaoha.Ha ho bapisoa le li-valve tsa heke le li-valve tsa globe, ts'ebetso e fetoha habonolo mme switch e potlakile.Sephahla sa plug se sebelisa 'mele oa plug o nang le lesoba e le setho se bulang le se koalang,' me 'mele oa plug o potoloha le kutu ea valve ho hlokomela ketso ea ho bula le ho koala.
Lenane la ts'ebeliso ea li-valve tsa plug tse tloaelehileng tsa Amerika:
Sekhahla sa ferrule se tloaelehileng sa Amerika se loketse liphaephe tsa khatello ea lebitso CLASS150~CLASS600LB, mocheso o sebetsang oa -29°C~180°C bakeng sa petroleum, lik'hemik'hale, meriana, manyolo, indasteri ea matla a motlakase, joalo-joalo Pipeline media.
Likarolo tsa sebopeho sa li-valve tsa plug tse tloaelehileng tsa Amerika:
1. Sehlahisoa se na le sebopeho se utloahalang, ho tiisa ho ka tšeptjoang, ts'ebetso e babatsehang le ponahalo e ntle.
2, ho tiisoa ha valve ea socket welding plug ho finyelloa ka holim'a ho tiisa ho potoloha ferrule.Motsoako o ikhethang oa 360° oa tšepe o sireletsang molomo.
3. Belofo ha e na sekoti ho bokella sehare.
4, molomo oa tšepe o fana ka phello ea ho itlhoekisa ha mokōkō o reteleha, o loketse bakeng sa viscous le ho lekanya habonolo.
5, phallo ea litsela tse peli, e bonolo ho e sebelisa le ho e kenya.
6. Thepa le boholo ba li-flange tsa likarolo li ka lumellana ka mokhoa o utloahalang ho ea ka maemo a sebele a ho sebetsa kapa litlhoko tsa mosebedisi ho finyella litlhoko tse sa tšoaneng tsa boenjiniere.
