Pob li qubthiabnpauj npaim li qub yog ob pawg tseem ceeb ntawm cov li qub thiab tau siv dav.Lub pob valve yuav tsum nruj sealing ntawm qhov kub thiab txias thiab kev kub siab thiab tsis tshua muaj dej tsis kam.Npauj npaim li qub feem ntau yog siv rau kev ua haujlwm nrog lub siab tsis tshua muaj siab thiab tsis tshua muaj kev sib khi.
Kuj tseem muaj ntau yam kev faib tawm ntawm pob li qub thiab npauj npaim li qub.Cov pob li qub tuaj yeem muab faib ua: hlau tawv-pob pob li qub, mos-pob pob li qub, ntab pob li qub, pob pob li qub, eccentric semi-pob li qub, V-shaped regulating pob li qub, thiab lwm yam.
Npauj npaim valve muab faib ua: peb eccentric npauj npaim valve, ob chav eccentric npauj npaim valve, centerline npauj npaim valve, nyuaj sealing npauj npaim valve, mos sealing npauj npaim valve.
Pob li qub thiab npauj npaim li qub yog feem ntau siv li qub.Qee zaum, ob qho tib si tuaj yeem siv rau hauv kev siv ntau, thiab hauv qee qhov kev ua haujlwm, tsuas yog ib qho ntawm lawv tuaj yeem siv tau.Cov yam ntxwv ntawm ob hom li qub.Peb piav qhia luv luv:
Pob valve: lub pob valve hloov zuj zus, qhov qhib thiab kaw yog ib puag ncig, cov yam ntxwv yog:
1. Kev ua haujlwm tsis zoo yog me me.Thaum qhib tag nrho, tsis muaj qhov thaiv qhov ntws ntawm qhov nruab nrab hauv cov channel;
2. Nws tuaj yeem raug kaw tag nrho nyob rau hauv siab dua thiab kub dua;
3. Nws tuaj yeem qhib thiab kaw sai;
4. Paub qhov hnav tsis kam thiab muaj zog corrosion los ntawm kev kho hardening;
5. Lub cev valve yog symmetrical, uas tuaj yeem tiv taus cov kav dej siab thiab tuaj yeem tiv taus cov kev ua haujlwm siab.
Npauj npaim valve: Qhov qhib thiab kaw yog ib qho disc hom npauj npaim phaj, uas yog tus cwj pwm los ntawm:
1. Cov qauv yooj yim, me me thiab yooj yim installation;
2. Me me ntws tsis kam coefficient, ceev qhib thiab kaw;
3. Nws tuaj yeem siv rau qhov loj txoj kab uas hla;
4. Qhov sib txawv sealing nto tuaj yeem siv rau hauv ntau qhov chaw, suav nrog cov hmoov nplej thiab granular media.
Piv nrog rau lub pob valve, npauj npaim valve muaj qhov ua tau zoo me ntsis ntawm kev sib khi, tab sis ntawm qhov loj-inch li qub, npauj npaim valve muaj qhov tshwj xeeb zoo dua lub pob valve;Thaum siv los kho tus nqi ntws, tus npauj npaim valve muaj qhov hloov me me, thaum lub V-hom hloov pob valve yog kho tau.Nyob rau hauv high-pressure pipelines, pob li qub muaj qhov zoo dua li npauj npaim li qub.
