Ntau yam tswj li qub tuaj nyob rau hauv ntau hom lub cev, feem ntau suav nrog ib zaug - rooj zaum, ob chav - lub rooj, lub kaum sab xis, diaphragm, qis- ntws, peb- txoj kev, eccentric rotary, npauj npaim, lub tes tsho, thiab pob li qub. Thaum xaiv lub valve, xav txog cov hauv qab no:
1. Feem ntau xav txog cov yam ntxwv ntws thiab tsis muaj zog.
2. Thaum cov kua nruab nrab yog lub ncua kev kawm ntawv uas muaj ib tug siab concentration ntawm abrasive hais, lub valve lub sab hauv cov ntaub ntawv yuav tsum robust.
3. Vim yog qhov corrosive qhov nruab nrab, xaiv li qub nrog cov qauv yooj yim thaum twg los tau.
4. Thaum qhov nruab nrab qhov kub thiab txias yog siab thiab hloov pauv ntau, xaiv li qub uas nws cov ntaub ntawv tseem ceeb thiab lub rooj zaum tsis tshua cuam tshuam los ntawm qhov kub thiab txias hloov.
5. Flashing thiab cavitation tsuas yog tshwm sim hauv cov kua xov xwm. Hauv cov txheej txheem tsim khoom tiag tiag, flashing thiab cavitation tuaj yeem tsim kev vibration thiab suab nrov, shortening valve lifespan. Yog li ntawd, xaiv valve yuav tsum tsom kom tsis txhob flashing thiab cavitation.
