American Standard alxankaKu xidh ValveSharaxaad Kooban:
Waalka furku wuxuu leeyahay qaab-dhismeed fudud, beddel degdeg ah, iska caabin dareere yar ah, iyo hawl-dhiigga xagasha oo degdeg ah.Xaalad degdeg ah sida shil, dhuumaha si degdeg ah ayaa loo xidhi karaa ama waa la gooyn karaa.Marka la barbar dhigo valves gate iyo globe valves, qalliinku wuu dabacsan yahay oo beddelku wuu dheereeyaa.Waalka furku waxa uu isticmaalaa jidh fur leh oo dalool ah sida xubinta furitaanka iyo xidhitaanka, jidhkuna waxa uu la wareegaa jirida waalka si uu u ogaado ficilka furitaanka iyo xidhitaanka.
Codsiga alxanka caadiga ah ee Ameerikaanku wuxuu kala duwan yahay:
Waalka alxanka alxanka caadiga ah ee Ameerika wuxuu ku habboon yahay tuubooyinka cadaadiska magaca CLASS150~CLASS600LB, heerkulka shaqada ee -29°C~180°C ee batroolka, kiimikooyinka, dawooyinka, bacriminta, warshadaha korontada, iwm. Warbaahinta Dhuumaha.
Qaab dhismeedka alxanka caadiga ah ee Ameerikaanku wuxuu leeyahay:
1. Alaabtu waxay leedahay qaab-dhismeed macquul ah, xirid la isku halleyn karo, waxqabad aad u fiican iyo muuqaal qurux badan.
2, xidhidhiyaha ee godka alxanka godka waxaa lagu gaaraa by dusha shaabadeynta agagaarka ferrule ah.360° biraha ilaalinta bishimaha gaarka ah.
3. Waalku ma laha dalool uu ku ururiyo dhexdhexaadka.
4, bushimaha birta ah waxay bixisaa saameyn is-nadiifin ah marka cirifka la leexiyo, oo ku habboon fiiqan iyo xoqin fudud.
5, socodka labada dhinac, fududahay in la isticmaalo oo la rakibo.
6. Maaddada iyo xajmiga qaybaha qaybaha si macquul ah ayaa loo waafajin karaa iyadoo loo eegayo shuruudaha shaqada ee dhabta ah ama shuruudaha isticmaalaha si loo daboolo baahiyaha injineernimada ee kala duwan.
