Sealing yog los tiv thaiv kom tsis txhob tawm, yog li cov hlau stainless valve sealing txoj cai tseem yog los ntawm kev tiv thaiv kev tshawb fawb to. Muaj ob yam tseem ceeb uas ua rau kom muaj dej ntws tawm, ib qho yog qhov tseem ceeb cuam tshuam rau kev ua haujlwm sealing, uas yog, muaj qhov sib txawv ntawm lub sealing vice, thiab lwm yam yog lub siab sib txawv ntawm ob sab ntawm sealing vice. Lub hauv paus ntsiab lus ntawm stainless hlau valve sealing tseem yog los ntawm cov kua sealing, gas sealing, to channel sealing txoj cai, thiab stainless hlau valve sealing lwm yam thiab lwm yam plaub yam los soj ntsuam.
1. Ua kua sealing
Cov kua sealing yog ua los ntawm viscosity thiab nto nro ntawm cov kua. Thaum lub stainless hlau valve xau capillary uas muaj cov pa roj, qhov nro tuaj yeem ua kua rov ua kua, lossis cov kua rau hauv lub capillary. Qhov no tsim lub kaum sab xis ntawm tangency. Thaum lub kaum sab xis ntawm tangency tsawg dua 90 degree, cov kua yog txhaj rau hauv lub capillary, thiab cov xau tshwm sim.
Yog vim li cas rau kev xau yog qhov sib txawv ntawm qhov nruab nrab. Qhov kev sim nrog cov xov xwm sib txawv, nyob rau hauv tib lub sijhawm, yuav muab cov txiaj ntsig sib txawv. Koj tuaj yeem siv dej, cua lossis roj av, thiab lwm yam. Cov dej ntws tuaj yeem tshwm sim thaum lub kaum sab xis ntawm tangency siab dua 90 degree. Qhov no yog vim muaj kev sib raug zoo nrog cov greasy los yog waxy films ntawm cov hlau nto. Thaum cov yeeb yaj kiab ntawm cov chaw no tau yaj lawm, cov khoom ntawm cov hlau nto hloov pauv, thiab cov kua uas tau tawm ntawm qhov chaw yuav ntub thiab ntws. Rau qhov teeb meem saum toj no, raws li Poisson cov mis, lub capillary txoj kab uas hla thiab nruab nrab viscosity yuav raug txo nyob rau hauv cov ntaub ntawv ntawm loj kom ua tiav lub hom phiaj ntawm kev tiv thaiv to los yog txo tus nqi ntawm to.
2. Cov roj sealing
Raws li Poisson tus qauv, cov roj foob nrog cov roj molecules thiab roj viscosity. Cov dej xau yog inversely proportional rau qhov ntev ntawm capillary thiab viscosity ntawm cov pa roj thiab proportional rau txoj kab uas hla ntawm capillary thiab lub zog tsav. Thaum txoj kab uas hla ntawm capillary thiab qhov nruab nrab ntawm kev ywj pheej ntawm cov roj molecules yog tib yam, cov roj molecules yuav ntws mus rau hauv capillary nrog dawb thermal txav.
Yog li ntawd, thaum peb ua qhov kev sim sealing ntawm stainless hlau li qub, qhov nruab nrab yuav tsum yog dej kom ua tiav cov nyhuv sealing, thiab huab cua, piv txwv li, roj, yuav tsis muaj peev xwm ua tiav cov nyhuv sealing. Txawm hais tias peb txo txoj kab uas hla ntawm lub raj capillary kom qis dua qib molecular ntawm cov pa los ntawm cov yas deformation, peb tseem tsis tuaj yeem tso tseg cov roj ntws. Yog vim li cas rau qhov no yog tias cov roj tseem tuaj yeem cuam tshuam los ntawm cov phab ntsa hlau. Yog li peb yuav tsum nruj dua li qhov ntsuas kua thaum peb ua qhov ntsuas roj.
3, Lub hauv paus ntsiab lus sealing ntawm to channel
Stainless hlau valve foob muaj ob qhov chaw: qhov tsis sib xws ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv thiab qhov roughness ntawm corrugation degree ntawm qhov kev ncua deb ntawm cov crests. Nyob rau hauv peb lub teb chaws, feem ntau ntawm cov hlau cov ntaub ntawv elastic hom yog tsawg, yog hais tias koj xav mus cuag ib lub xeev kaw, koj yuav tsum tau muab siab dua cov kev xav tau ntawm compression quab yuam ntawm cov khoom hlau, uas yog, cov ntaub ntawv compression quab yuam kom tshaj nws elasticity.
Yog li ntawd, nyob rau hauv kev tsim ntawm stainless hlau li qub, lub foob yog ua ke nrog ib tug tej yam hardness sib txawv kom phim cov nyhuv ntawm sealing nyob rau hauv lub siab, uas yuav tsim ib tug tej yam degree ntawm yas deformation. Yog hais tias lub sealing nto yog tag nrho cov khoom siv hlau, ces qhov tsis sib xws ntawm qhov projection point yuav tshwm sim thaum ntxov, hauv thawj zaug yuav tsum tau siv cov khoom me me xwb.
