1. Npauj npaim valve muaj cov yam ntxwv ntawm cov qauv yooj yim, ntim me me, lub teeb yuag, kev siv khoom me me, kev teeb tsa me me, kev hloov ceev, 90 ° kev sib hloov, kev tsav tsheb me me, thiab lwm yam, siv los txiav tawm, txuas, kho qhov nruab nrab hauv lub raj xa dej, nrog cov yam ntxwv tswj dej zoo thiab kaw tau zoo ua haujlwm.
2. Npauj npaim valve tuaj yeem thauj cov av nkos, ntawm lub qhov ncauj ntawm qhov ua kom muaj kua ntau dhau. Thaum tsis tshua muaj siab, kev sib khi zoo tuaj yeem ua tiav. Kev hloov kho tau zoo.
3. Kev tsim tus qauv ntawm cov npauj npaim phaj ua rau cov kua dej tsis tuaj yeem ua kom me me. Nws tuaj yeem hais tau tias nws yog lub zog txuag hluav taws xob.
4. Lub pob valve yog los ntawm cov qauv pas nrig, tom qab quenching thiab tempering kho, muaj cov khoom zoo txhua yam thiab kev ua hauj corrosion, tiv thaiv tsis kam. Thaum npauj npauj npaim valve qhib thiab kaw, lub qia tsuas tig thiab tsis sawv thiab ntog. Kev ntim ntawm lub qia tsis yooj yim raug rhuav pov tseg thiab lub foob tau ntseeg siab. Nws yog tsau nrog disc taper tus pin, thiab qhov kev hloov siab kawg yog tsim los tiv thaiv cov qia los ntawm kev tawg thaum lub qia thiab disc txuas nrog los ntawm kev sib tsoo.
5. Muaj qhov txuas flange, txuas txuas, taub qab txuas txuas thiab lug txuas clamp.
Daim ntawv tsav tsheb yog phau ntawv, cua tshuab tsav, hluav taws xob, pneumatic, hydraulic, hluav taws xob-hydraulic sib txuas thiab lwm tus neeg ua haujlwm, tuaj yeem paub cov chaw taws teeb tswj thiab kev ua haujlwm tsis siv neeg.
