Valavu Yoyang'anira Yolowera Pamwamba
Kodi Valve Yoyang'anira Kulowa Yapamwamba Ndi Chiyani?
Ma valve owunikira, ma valve osabwezera, apangidwa kuti aletse kutembenuka kwa kayendedwe ka madzi mu dongosolo la mapaipi. Ma valve awa amayatsidwa ndi zinthu zomwe zimayenda mupaipi.Kupanikizika kwa madzi omwe amadutsa mu dongosolo kumatsegula valavu, pomwe kutembenuka kulikonse kwa kayendedwe ka madzi kudzatseka valavu.Kutseka kumachitika ndi kulemera kwa makina owunikira, ndi kupanikizika kwa msana, ndi kasupe, kapena kuphatikiza njira izi.
Valavu Yoyang'anira Yolowera Pamwambayopangidwa ndi kupangidwa motsatira ASME B16.34, yesani ndikuyang'ana API598, API6D.
Vavu yolowera pamwamba yokhala ndi mpando, khola, diski ndi boneti yochotseka imagwiritsa ntchito ulusi wolumikizana wa mpando ndi cholumikizira cholumikizira m'thupi la valavu kuti ipewe kuyenda kwa mpando, khola ndi diski kumbali ya kumunsi kwa mtsinje. Phewa lozungulira m'thupi la valavu limaletsa kuyenda kwa mpando, khola ndi diski kumbali ya kumtunda.
