Kev sib khi yog txhawm rau tiv thaiv kom tsis txhob tawm, thiab lub hauv paus ntsiab lus ntawm lub valve sealing kuj tau kawm los ntawm kev tiv thaiv cov pa tawm. Muaj ntau yam uas cuam tshuam rau kev ua haujlwm sealing ntawmnpauj npaim li qub, feem ntau suav nrog cov hauv qab no:
1. Sealing qauv
Nyob rau hauv qhov kev hloov ntawm qhov kub thiab txias los yog sealing quab yuam, cov qauv ntawm lub sealing khub yuav hloov. Ntxiv mus, qhov kev hloov pauv no yuav cuam tshuam thiab hloov lub zog ntawm cov khub sib khi, yog li txo qhov kev ua haujlwm ntawm lub valve sealing. Yog li ntawd, thaum xaiv lub foob, nco ntsoov xaiv lub foob nrog elastic deformation. Nyob rau tib lub sij hawm, kuj xyuam xim rau lub thickness ntawm sealing nto. Yog vim li cas yog qhov kev sib cuag ntawm lub sealing khub tsis tuaj yeem ua tiav tag nrho. Thaum qhov dav ntawm kev sib cuag ntawm qhov chaw sealing nce, lub zog xav tau rau kev sib khi yog nce.
2. Tshwj xeeb siab ntawm sealing nto
Lub siab tshwj xeeb ntawm sealing nto cuam tshuam rau kev ua haujlwm sealing ntawmnpauj npaim valvethiab kev pabcuam lub neej ntawm lub valve. Yog li ntawd, qhov tshwj xeeb siab ntawm sealing nto kuj yog ib qho tseem ceeb heev. Nyob rau tib lub sijhawm, qhov tshwj xeeb siab heev yuav ua rau lub valve puas, tab sis qhov tshwj xeeb me me yuav ua rau valve to. Yog li ntawd, peb yuav tsum xav txog qhov tsim nyog ntawm qhov tshwj xeeb siab thaum 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 ua haujlwm ntawmnpauj npaim valve. Cov khoom ntawm lub cev no suav nrog qhov kub thiab txias, viscosity, thiab hydrophilicity ntawm qhov chaw, thiab lwm yam. Qhov kub hloov pauv tsis tsuas yog cuam tshuam qhov slackness ntawm lub sealing khub thiab kev hloov ntawm qhov loj ntawm cov khoom, tab sis kuj muaj kev sib raug zoo nrog cov viscosity ntawm cov roj. Gas viscosity nce los yog txo nrog nce los yog txo qhov kub thiab txias. Yog li ntawd, txhawm rau txo qhov cuam tshuam ntawm qhov kub thiab txias ntawm qhov kev sib khi ntawm lub valve, thaum tsim lub sealing khub, peb yuav tsum tsim nws li lub valve nrog thermal them nyiaj xws li lub rooj zaum elastic valve. Viscosity yog txuam nrog permeability ntawm cov kua. Thaum nyob rau hauv tib yam kev mob, qhov ntau dua qhov viscosity, qhov tsawg dua qhov nkag tau ntawm cov kua. Lub hydrophilicity ntawm nto txhais tau hais tias thaum muaj ib zaj duab xis ntawm cov hlau nto, cov zaj duab xis yuav tsum tau muab tshem tawm. Vim tias cov roj no nyias nyias, nws yuav rhuav tshem cov hydrophilicity ntawm qhov chaw, ua rau muaj kev cuam tshuam ntawm cov kua dej.
4. Qhov zoo ntawm kev sib khi khub
Qhov zoo ntawm cov sealing khub feem ntau txhais tau hais tias peb yuav tsum kuaj xyuas cov kev xaiv, sib txuam thiab tsim cov khoom raug. Piv txwv li, lub valve disc haum zoo nrog lub valve lub rooj sealing nto, uas tuaj yeem txhim kho qhov kev sib khi.
Valve leakage feem ntau tshwm sim hauv lub neej thiab kev tsim khoom, uas tuaj yeem ua rau cov khoom pov tseg lossis ua rau muaj kev phom sij rau lub neej, xws li cov dej ntws tawm ntawm cov kav dej, thiab cov kev tshwm sim loj heev, xws li tshuaj lom, muaj teeb meem, flammable, explosive thiab leakage ntawm corrosive media, thiab lwm yam. , yog ib qho kev hem thawj loj rau kev nyab xeeb ntawm tus kheej, kev nyab xeeb ntawm vaj tse thiab ib puag ncig muaj kuab paug. Xaiv cov ntsaws ruaj ruaj raws li qhov chaw sib txawv thiab siv cov yam ntxwv.
