Lub Tsheb Gasket yog dab tsi?

Lub gasket yog lub tshuab foob ntawm ob yam khoom, feem ntau yog siv los tiv thaiv ob yam khoom los ntawm compressed, corroded, thiab cov kav dej los ntawm ib txwm xau vim thermal expansion thiab contraction. Txij li thaum lub tshuab nto tsis tuaj yeem ua tau zoo tag nrho, qhov tsis sib xws tuaj yeem sau nrog gaskets. Hom tsheb gaskets:
1. Lub tshuab ntxhua khaub ncaws yog ib feem ntawm qhov txuas thiab cov txiv ntoo, feem ntau yog lub nplhaib hlau tiaj tus.
2. Cov gaskets uas tsis yog xim hlau yog ua los ntawm asbestos, roj hmab, hluavtaws cob, PTFE thiab lwm yam khoom tsis yog xim hlau. Lub gasket uas tsis yog xim hlau yog ib qho uas tsis yog xim hlau coated nrog ib txheej ntawm hluavtaws cob.
3. Semi-metallic gaskets Semi-metallic gaskets yog gaskets ua los ntawm cov hlau thiab cov ntaub ntawv uas tsis yog xim hlau, xws li lub qhov txhab gaskets thiab hlau-coated gaskets.
4. Spiral Wound Gasket yog ib lub gasket uas tsim los ntawm helically winding ib tug hlau sawb thiab ib tug uas tsis yog-hlau strip nrog ib tug V-shaped los yog W-shaped cross section. Lub nplhaib puab yog muab pov tseg rau ntawm lub nplhaib hlau qhov txhab nyob ib ncig ntawm lub nplhaib puab ntawm lub gasket. Lub nplhaib sab nraud yog muab pov tseg rau ntawm lub nplhaib hlau qhov txhab nyob ib ncig ntawm lub nplhaib sab nraud ntawm lub gasket. Hlau Washers Washers ua los ntawm hlau, txhuas, tooj liab, npib tsib xee los yog Monel. Qhov txhab gasket yog hais txog lub gasket uas raug mob rau hauv lub nplhaib nrog txoj siv hlau (feem ntau yog V-shaped steel siv) thiab txoj siv tsis yog xim hlau. Hlau thiab non-metallic strips yog hloov pauv qhov txhab. Vim nws zoo elasticity, nws yog dav siv nyob rau hauv flange sealing qauv hauv petrochemical, tshuaj, hluav taws xob thiab lwm yam lag luam. Raws li cov khoom tshwj xeeb, lub nplhaib hlau tuaj yeem muab ntxiv rau sab hauv lossis txheej txheej ntawm lub gasket rau qhov chaw lossis kev txhawb nqa.
