Ob leeg tuav npauj npaim li qub thiab cab iav npauj npaim li qub xav tau kev ua haujlwm ntawm phau ntawv, feem ntau hu ua phau ntawv npauj npaim li qub, tab sis tseem muaj qhov sib txawv ntawm lawv siv.
1. Tus kov ntawm tus npauj npaim valve ncaj qha tsav lub valve phaj, ua rau nws ceev hloov tab sis ua haujlwm hnyav; Tus cab iav npauj npaim valve tsav lub phaj valve los ntawm cov iav iav, uas yog qeeb qhib thiab kaw tab sis txuag zog. Yog li ntawd, thaum lub siab nyob rau hauv lub pipeline yog siab, xaiv ib tug kov npauj npaim valve yuav ua hauj lwm tshwj xeeb. Nws raug nquahu kom koj xaiv lub iav iav npauj npaim valve.
2. Feem ntau siv npauj npaim li qub hauv engineering feem ntau yog worm iav npauj npaim li qub, vim tias ntxiv rau kev txuag hluav taws xob, lawv cov sealing kev ua tau zoo kuj zoo dua li tuav npauj npaim li qub. Tshwj xeeb tshaj yog nyob rau hauv ib puag ncig uas muaj kev hloov pauv ntau zaus, worm iav npauj npaim li qub muaj lub neej ua haujlwm ntev dua li tuav npauj npaim li qub.
3. Kov npauj npaim li qub feem ntau yog siv nrog cov kab me me (hauv DN200), vim tias lub zog ntawm cov kab npauj npaim valve feem ntau me dua thiab tuaj yeem qhib thiab kaw ncaj qha los ntawm tes. Cov kab npauj npaim npauj npaim li qub siv lub iav iav los tsav lub qia kom tig, uas yog kev txuag nyiaj ntau dua.
Cov ntsiab cai ntawm kev xaiv rau kov tsav thiab cab iav tsav:
Thaum lub torque ntawm lub valve qia yog ntau tshaj 300N · M, ib tug gearbox tsav yog siv, thiab tus so feem ntau yog tsav los ntawm ib tug kov.
