Kev xaiv cov khoom siv gasket tsim nyog yuav tsum xav txog cov hauv qab no
1, Cov xwm txheej ua haujlwm
Kub: Xaiv cov khoom siv gasket raws li qhov kub ntawm qhov nruab nrab. Piv txwv li, roj hmab asbestos pads tuaj yeem siv rau qhov kub thiab txias, thaum cov ntaub qhwv hlau los yog PTFE gaskets yuav tsum tau txiav txim siab ntawm qhov kub thiab txias.
Siab: Txiav txim siab lub peev xwm ntawm cov khoom siv gasket raws li kev ua haujlwm siab. Cov ntaub ntawv muaj zog xws li hlau winding pads yuav tsum tau xaiv nyob rau hauv ib puag ncig siab.
Cov khoom nruab nrab: Xav txog yam xws li corrosiveness thiab oxidizability ntawm nruab nrab. Corrosive media tuaj yeem siv cov hlau tsis muaj steel lossis polytetrafluoroethylene gaskets, thaum oxidizing media yuav tsum xaiv cov khoom uas muaj oxidation zoo.
2, Gasket hom thiab qauv
Gasket hom: Xaiv hom gasket raws li hom flange nto. Piv txwv li, hlau qhwv gaskets feem ntau yog siv rau tsa flanges, thaum hlau qhwv gaskets nrog rings puab yuav siv tau rau tsa flanges.
Gasket qauv: Xav txog cov qauv ntawm lub gasket, xws li cov xov sab hauv, cov xov sab nraud, thiab lwm yam, thiab seb nws puas tsim nyog ntxiv cov nplhaib sab hauv thiab sab nrauv los txhim kho kev sib khi.
3, Khoom yam ntxwv
Corrosion tsis kam: Xaiv cov ntaub ntawv uas muaj kev tiv thaiv corrosion zoo los xyuas kom lub sijhawm ruaj khov ntawm lub gasket hauv corrosive media.
Elasticity thiab resilience: Gaskets yuav tsum muaj zoo elasticity thiab resilience los xyuas kom meej sealing zoo nyob rau hauv lub siab hloov.
Kev kub siab tiv thaiv: Rau qhov kub thiab txias ib puag ncig, cov ntaub ntawv uas tuaj yeem tiv taus qhov kub thiab txias, xws li cov ntaub qhwv lub qhov txhab hlau lossis polytetrafluoroethylene gaskets, yuav tsum tau xaiv.
