Stainless hlau wafer kos valve yog ib qho tsis siv neeg valve nrog ntau tus qauv thiab specifications.Cov khoom siv no yog siv los tiv thaiv qhov rov qab ntawm qhov nruab nrab, qhov rov qab tig ntawm lub twj tso kua mis thiab nws lub cev muaj zog, thiab tawm ntawm qhov nruab nrab hauv lub thawv.Nws tuaj yeem siv rau ntau yam ntawm cov kab nruab nrab.Yog li cas peb xaiv lub stainless hlau wafer kos valve?Dab tsi yuav tsum tau them nyiaj rau?
1. Nws yog feem ntau pom zoo kom cov neeg siv xaiv hlau hard-sealed wafer kos li qub kom ntseeg tau tias wafer check li qub muaj lub neej ua haujlwm ntev, kev ua haujlwm siab dua, thiab kev sib khi zoo tib yam.
2. Yog tias qhov nominal loj dua los yog sib npaug rau DN100 (NPS4), nws raug nquahu kom xaiv covH76 hom ob chav disc viav vias wafer kos valve, uas tuaj yeem txo qhov poob ntawm cov kua dej tsis zoo ntawm daim tshev valve;qhov nominal loj yog tsawg dua los yog sib npaug rau DN80 (NPS3), thiab kev xaiv H71 hom nqa daim tshev valve yog tsim nyog.
3. CovH71 nqa hom wafer kos valvenrog rau qhov nominal loj tsawg dua los yog sib npaug rau DN100 (NPS) feem ntau tsis tsim vim nws cov qauv compact thiab xav txog kev ua thiab kev tsim khoom.Nws raug nquahu kom cov neeg siv xaiv stainless hlau nqa hom wafer kos li qub.valve.
4. Ntxiv rau hom wafer, stainless hlau ob chav disc viav vias kos valve kuj muaj hom lug thiab flange hom.Yog tias tus neeg siv tsis muaj qhov tshwj xeeb, daim ntawv qauv feem ntau yog tsim los ntawm peb lub tuam txhab raws li cov qauv kev cai.Qee qhov ob chav disc viav vias kos li qub tuaj yeem tsim nrog ob lub flange qauv (hom H46).
5. Lub lug flange ntawm lub lug ob lub ntsej muag viav vias kos valve tsuas yog ua lub luag haujlwm ntawm qhov chaw, thiab lub lug tsis dais lub bolt quab yuam, yog li lub thickness ntawm lub lug flange tsis yog tsim raws li lub thickness ntawm tus qauv flange, feem ntau. lub lug flange Lub thickness yog tsawg tshaj li tus qauv flanges.Lub flange ntawm ob lub flange kev twb kev txuas ob disc viav vias kos valve bears lub ntsia liaj qhov rooj quab yuam, thiab lub flange thickness yog tsim raws li tus qauv flange.
6. Lub lift-type wafer check li qub nrog nominal pressures PN10, PN16, PN25 thiab PN40 muaj ob qhov ntev ntawm cov qauv.Tus nqi ntawm luv luv check li qub yog qis dua, tab sis tsis yog-tus qauv kev twb kev txuas gaskets yuav tsum tau nyob nruab nrab ntawm lub check valve thiab lub raj flange.Yog tias siv cov khoom siv ntev ntev, cov qauv flange gaskets tuaj yeem npaj tau.
