Qhov no yog qhov tseem ceeb tshwj xeeb rau cov tshuab tuav cov tshuaj lom, corrosive, viscous lossis flammable media.
2. Kev ua haujlwm zoo sealing: Diaphragm valve muaj kev sib khi zoo thiab tuaj yeem tiv thaiv qhov nruab nrab to. Lub diaphragm ib feem ntawm lub valve tuaj yeem hloov kho kom haum rau cov kev hloov pauv hauv nruab nrab thiab muab cov nyhuv sealing txhim khu kev qha.
3. Corrosion kuj: Cov khoom xaiv ntawm lub diaphragm valve tuaj yeem hloov kho raws li cov yam ntxwv ntawm qhov nruab nrab, yog li muab kev tiv thaiv corrosion ntau dua. Qhov no ua rau lub diaphragm valve haum rau lub tshuab tuav corrosive media xws li acids, alkalis, thiab ntsev.
4. Kev tswj hwm kev ua tau zoo: Lub diaphragm valve muaj cov kev cai loj txaus thiab kev poob siab me me, thiab tuaj yeem ua tiav cov dej ntws zoo tswj raws li kev ua haujlwm sib txawv.
5. Kev ntseeg siab: Lub diaphragm valve muaj cov qauv yooj yim thiab ob peb ntu, yog li nws muaj kev ntseeg siab thiab cov nqi kho mob tsawg. Cov diaphragm feem ntawm lub valve yog hloov tau yooj yim thiab kho tau, muab diaphragm li qub kom zoo dua hauv cov ntawv thov uas yuav tsum tau saib xyuas tas li.
Nws yuav tsum raug sau tseg tias diaphragm li qub kuj muaj qee qhov kev txwv. Piv txwv li, qhov kev hloov pauv qhov tseeb tsis zoo li lwm hom li qub, thiab lawv tsim nyog rau cov xwm txheej nrog qis qis thiab qis qis qis. Yog li ntawd, thaum xaiv lub valve, cov yam ntxwv xws li cov kev xav tau ntawm lub cev, cov yam ntxwv nruab nrab, thiab kev ua haujlwm yuav tsum tau txiav txim siab.
