Flange pob valve yog lub valve nyob rau hauv uas qhib thiab kaw qhov chaw (pob) yog tsav los ntawm lub pob valve thiab tig ib ncig ntawm lub axis ntawm lub pob valve. Lub pob valve yog siv rau kev txiav tawm, faib thiab hloov cov kev coj mus los ntawm qhov nruab nrab hauv qhov raj dej.
Pob valve yog cov dav siv valve, nws muaj qhov zoo hauv qab no:
1. Cov kua dej tsis kam yog qhov me me, thiab nws cov kuj tiv thaiv sib npaug yog qhov sib npaug ntawm cov yeeb nkab ntu ntawm tib qhov ntev.
2. Cov qauv yooj yim, loj me thiab lub teeb yuag.
3. Nws yog nruj thiab txhim khu kev qha. Lub ntsej muag sib khi ntawm lub pob valve yog ua los ntawm cov yas dav, uas muaj kev ua tau zoo sealing thiab tau siv dav hauv tshuab nqus tsev.
4. Kev lag luam yooj yim, qhib sai thiab kaw, tsuas yog yuav tsum tig 90 ° los ntawm kev qhib siab kom puv kaw, uas yooj yim rau kev tswj chaw taws teeb.
5. Kev saib xyuas kom yooj yim, cov qauv yooj yim ntawm lub pob valve, feem ntau txav tau yooj yim lub nplhaib, yooj yim rhuav tshem thiab hloov.
6. Thaum qhib tag nrho lossis kaw tag nrho, lub npoo ntawm lub pob sib khi thiab lub rooj sib tw lub rooj sib cais los ntawm qhov nruab nrab, thiab qhov nruab nrab yuav tsis ua rau muaj kev yaig ntawm lub valve sealing nto thaum qhov nruab nrab hla.
7. Nws muaj ntau hom ntawm kev siv, nrog rau txoj kab uas hla ntawm ob peb millimeters mus rau ob peb metres, thiab tuaj yeem siv los ntawm lub tshuab nqus tsev siab mus rau kev siab siab.
