Khoom nta ntawm oxygen tshwj xeeb nres valve
Cov khoom no tsis tsuas yog muaj kev ua haujlwm ntawm lub valve, tab sis kuj muaj nws tus yam ntxwv. Cov kev txwv tsis pub roj nruj yog tau txais thaum lub sijhawm tsim khoom, thiab txhua qhov chaw yog nruj me ntsis degreased ua ntej kev teeb tsa. Lub flange kawg ntawm txhua qhov ntau thiab tsawg ntawm cov li qub yog muab nrog cov ntsia hlau ua kom tsis txhob muaj hluav taws xob zoo li qub. Qhov chaw ntawm lub valve yuav tsum raug tiv thaiv los ntawm plua plav thiab roj paug. Cov khoom siv hauv cov khoom no tau muab faib ua ob pawg: ib qho yog cam khwb cia silicon tooj dag siv rau lub cev valve, lub kaus mom thiab disc; lwm yam yog zoo stainless hlau siv rau valve lub cev, lub kaus mom thiab disc.
