Kev ua haujlwm ntawm flange kos valve tsuas yog tso cai rau qhov nruab nrab ntws mus rau hauv ib qho kev taw qhia thiab tiv thaiv qhov ntws ntawm qhov kev taw qhia. Feem ntau hom valve ua haujlwm tau txais. Nyob rau hauv lub siab ntawm cov kua ntws nyob rau hauv ib qho kev taw qhia, lub valve disc qhib; Thaum cov kua dej ntws tawm mus rau qhov sib txawv, cov kua dej siab thiab tus kheej qhov hnyav ntawm lub valve disc ua rau lub rooj zaum valve, yog li txiav tawm qhov ntws.

Flange kos valve qauv thiab cov yam ntxwv
1. Cov ntaub ntawv raug xaiv ua tib zoo, ua raws li cov qauv hauv tsev thiab txawv teb chaws, thiab tag nrho cov khoom zoo yog siab.
2. Kev sib khi ntawm cov hlua khi yog siab heev thiab tsim nyog. Lub valve disc thiab valve lub rooj sealing nto yog ua los ntawm hlau-raws li alloy los yog Stellite cobalt-raws li nyuaj alloy nto nto, uas muaj zoo hnav tsis kam, kub tsis kam, corrosion kuj thiab khawb kuj. , kav ntev.
3. Cov khoom tsim thiab tsim raws li lub teb chaws tus qauv GB / T12235.
4. Ntau yam piping flange qauv thiab flange sealing hom tuaj yeem raug coj los ua kom tau raws li ntau yam kev xav tau ntawm engineering thiab cov neeg siv khoom.
5. Lub valve lub cev muaj ntau yam khoom siv, thiab cov gaskets tuaj yeem xaiv qhov tsim nyog raws li kev ua haujlwm tiag tiag lossis cov neeg siv yuav tsum tau ua, thiab tuaj yeem siv rau ntau lub siab, kub thiab nruab nrab ua haujlwm. Kos li qub nrog cov qauv sib txawv thiab cov ntaub ntawv sib txuas tuaj yeem tsim thiab tsim raws li tus neeg siv yuav tsum tau siv rau hauv ntau yam khoom siv.
