Lub tshuab ntxhua khaub ncaws: Ib qho khoom siv muab tso rau ntawm qhov txuas thiab cov txiv ntoo, feem ntau yog lub nplhaib hlau.
Tsis yog-metallic Gasket: Lub gasket ua los ntawm cov khoom tsis yog-hlau xws li asbestos, roj hmab, hluavtaws cob, thiab polytetrafluoroethylene. a. Tsis yog-xov tooj hlau Jacket Gasket: Tsis yog-metallic gasket nrog txheej txheej ntawm hluavtaws cob, thiab lwm yam.
Semi-metallic Gasket: Ib lub gasket ua los ntawm ob qho tib si hlau thiab tsis yog-cov ntaub ntawv hlau, xws li cov ntaub qhwv lub qhov txhab thiab cov hlau-cov ntaub nplaum. a. Spiral Wound Gasket: Ib lub gasket ua los ntawm spirally winding ib tug tsis yog -hlau strips sandwiched ntawm hlau strips nrog V-zoo li tus los yog W-zoo li tus ntoo khaub lig-sections. 1) puab nplhaib: lub nplhaib hlau nyob rau hauv lub nplhaib puab ntawm lub kauv qhov txhab gasket) Outering ntawm cov hlau: {10} kauv qhov txhab gasket. b.
