Npauj npaim li qub yog tsim rau cov kav xa dej thauj ntau yam corrosive thiab non-corrosive fluid media nyob rau hauv engineering systems xws li generators, thee gas, natural gas, liquefied petroleum gas, lub nroog gas, cua txias thiab kub, tshuaj smelting thiab lub zog tsim thiab kev tiv thaiv ib puag ncig, rau kev tswj hwm thiab kev cuam tshuam Kev khiav ntawm qhov nruab nrab.
Lub ntsiab yog vim li cas rau kev puas tsuaj ntawm cov mos mos sealing npauj npaim valve yog qhov tseeb tias lub valve tsis raug xaiv raws li kev ua haujlwm, thiab lub kaw lus kaw yog siv los ua lub kaw lus kaw, ua rau lub siab kaw ntau dhau thiab kaw nrawm dhau los tsis nruj, ua rau lub sealing nto yuav eroded thiab hnav. .Qhov kev yaig ntawm qhov nruab nrab yog qhov tshwm sim ntawm kev hnav, yaig thiab cavitation ntawm lub sealing nto thaum nruab nrab ntws.Yog li ntawd, nws yog ib qho tseem ceeb heev uas yuav tau xaiv cov khoom valve raws li kev siv ib puag ncig thiab kev ua haujlwm.
Yog vim li cas rau kev puas tsuaj ntawm lub sealing nto ntawm lub mos sealing npauj npaim valve yog cov neeg tsim kev puas tsuaj thiab kev puas tsuaj ntuj tsim.Man-ua kev puas tsuaj yog tshwm sim los ntawm tej yam xws li kev tsim tsis zoo, kev tsim khoom tsis zoo, kev xaiv cov khoom siv tsis zoo, kev teeb tsa tsis zoo, kev siv tsis zoo, thiab kev saib xyuas tsis zoo.
