Cov dej ntws tawm ntawm lub valve feem ntau tshwm sim hauv lub neej thiab kev tsim khoom, thiab qhov cuam tshuam loj heev, nws yuav tsis tsuas yog ua rau cov khoom pov tseg, tab sis kuj ua rau muaj kev phom sij rau lub neej, xws li cov dej ntws tawm ntawm cov kais dej valve, yuav ua rau muaj qhov tshwm sim loj.Valve. packing yog ib qho ntawm feem cuam tshuam ntawm lub valve kom to, tab sis cov laj thawj tuaj yeem muab faib ua cov hauv qab no.
1.Cov qauv ntawm lub sealing khub
Nyob rau hauv qhov kev hloov ntawm kub los yog sealing quab yuam, tus qauv ntawm sealing khub yuav hloov.Thiab qhov kev hloov no yuav cuam tshuam thiab hloov lub zog ntawm lub sealing khub, kom qhov kev ua tau zoo ntawm lub valve seal yog txo. Yog li ntawd, thaum xaiv cov ntsaws ruaj ruaj, peb. yuav tsum xaiv elastic seals.Tam sim no, peb yuav tsum tau them sai sai rau qhov dav ntawm lub sealing nto.Qhov laj thawj yog vim li cas qhov sib cuag ntawm lub sealing khub tsis zoo ib yam. Thaum qhov dav ntawm qhov sealing nto nce, nws yog ib qho tsim nyog yuav tsum tau ua kom muaj zog ntxiv rau kev sib khi.
2.Qhov tshwj xeeb siab ntawm lub sealing nto
Lub siab tshwj xeeb ntawm lub sealing nto cuam tshuam rau kev ua tau zoo sealing thiab kev pabcuam lub neej ntawm lub valve.Yog li ntawd, qhov tshwj xeeb siab ntawm sealing nto kuj yog ib qho tseem ceeb heev.Raws li tib lub sijhawm, ntau lub siab tshwj xeeb yuav ua rau kev puas tsuaj ntawm lub valve. , tab sis qhov tshwj xeeb me ntsis siab yuav ua rau cov pa tawm ntawm lub valve.Yog li ntawd, peb yuav tsum tau xav txog qhov tsim nyog tus nqi ntawm lub siab tshwj xeeb hauv kev tsim.
3.Lub cev muaj zog ntawm qhov nruab nrab
Cov khoom ntawm lub cev ntawm qhov nruab nrab kuj cuam tshuam rau kev sib khi ntawm lub valve.Cov khoom siv lub cev no suav nrog qhov kub thiab txias, viscosity, hydrophilicity ntawm qhov chaw thiab lwm yam.Qhov kev hloov ntawm qhov kub thiab txias tsis tsuas yog cuam tshuam rau kev so ntawm lub sealing khub thiab kev hloov ntawm ib feem dimension. , tab sis kuj muaj kev sib raug zoo nrog cov viscosity ntawm cov pa roj.Qhov viscosity ntawm cov pa nce lossis txo nrog qhov nce lossis txo qhov kub.Yog li ntawd, txhawm rau txo qhov cuam tshuam ntawm qhov kub thiab txias ntawm lub valve seal kev ua tau zoo, thaum peb tsim cov sealing khub. , peb yuav tsum tsim nws mus rau hauv lub valve nrog cov nyiaj kub kub.Viscosity muaj feem xyuam rau cov permeability ntawm cov kua.Nyob rau hauv tib yam kev mob, qhov ntau dua cov viscosity, qhov tsawg permeable cov kua yuav yog.Lub hydrophilicity ntawm lub nto txhais tau hais tias thaum muaj ib tug viscosity. nyias zaj duab xis ntawm cov hlau nto, cov zaj duab xis yuav tsum tau muab tshem tawm.Vim tias cov zaj duab xis nyias ntawm cov roj no tuaj yeem rhuav tshem cov hydrophilicity ntawm qhov chaw, ua rau muaj kev thaiv ntawm cov kua dej channel.
4.Qhov zoo ntawm sealing khub
Qhov zoo ntawm lub sealing khub feem ntau yog hais txog peb yuav tsum xyuas cov kev xaiv, kev sib txuam thiab kev tsim cov ntaub ntawv raug.Piv txwv li, ib qho zoo haum ntawm lub disc thiab lub rooj zaum sealing lub ntsej muag tuaj yeem txhim kho kev sib khi.
