Gaskets yog cov khoom tseem ceeb hauv kev sib txuas flanged, muab lub foob ntawm lub ntsej muag flange kom tiv thaiv kom tsis txhob muaj kua los yog roj. Muaj ntau hom gaskets muaj, txhua tus tsim los rau cov kev siv tshwj xeeb thiab kev ua haujlwm. Nov yog qee hom gaskets rau flanges thiab lawv siv:
1. Non-Metallic Gaskets:
- Compressed Non-Asbestos (CNA) Gaskets:Ua los ntawm cov hluavtaws fibers thiab cov fillers sib txuas nrog elastomers. Lawv tsim nyog rau cov ntawv thov dav dav uas muaj qhov kub thiab txias thiab cov xwm txheej siab.
- Roj Hmab Gaskets (Neoprene, EPDM, Nitrile):Cov gaskets no yog tsim los ntawm ntau yam khoom siv roj hmab thiab tsim nyog rau cov ntawv thov uas xav tau kev tiv thaiv dej, huab cua, thiab qee yam tshuaj. Lawv feem ntau yog siv rau hauv cov ntawv thov uas tsis tshua muaj siab thiab tsis kub.
- PTFE (Polytetrafluoroethylene) Gaskets:Paub txog lawv cov tshuaj tiv thaiv zoo heev thiab tsis muaj kev sib txhuam. PTFE gaskets yog tsim rau high-temperature thiab corrosive daim ntaub ntawv, xws li nyob rau hauv cov tshuaj thiab tshuaj industries.
2. Hlau Gaskets:
- Kauv qhov txhab Gaskets:Tsim nrog alternating txheej ntawm hlau winding sawb thiab muab tub lim (feem ntau graphite los yog PTFE). Kauv lub qhov txhab gaskets yog tsim rau kev siv high-pressure thiab high-temperature daim ntaub ntawv, muab zoo heev resilience thiab sealing kev ua tau zoo.
- Nplhaib Joint Gaskets:Tsim los kaw cov flanged kev sib txuas hauv high-pressure thiab high-temperature applications, xws li roj thiab roj pipelines. Lawv yog tsim los ntawm cov ntaub ntawv hlau (xws li, hlau mos, stainless hlau) thiab feature ib lub nplhaib tshwj xeeb nrog ib tug trapezoidal cross-section.
3. Composite Gaskets:
- Kampprofile Gaskets:Tsim los ntawm cov tub ntxhais hlau hlau thiab cov khoom siv ntsej muag (xws li graphite, PTFE) ntawm ob sab. Kammprofile gaskets muab lub zog ntawm cov hlau nrog kev ua haujlwm ntawm cov ntaub ntawv tsis yog xim hlau, ua rau lawv haum rau ntau qhov kub thiab txias.
- Corrugated Hlau Gaskets:Ua los ntawm nyias cov ntawv hlau nrog corrugated lossis serrated profiles. Corrugated hlau gaskets yog tsim rau high-pressure thiab high-temperature daim ntaub ntawv, muab zoo sealing kev ua tau zoo thiab tsis kam mus flange rotation.
4. Expanded PTFE Gaskets:
- Ua los ntawm cov khoom siv PTFE nthuav dav, cov gaskets no muaj cov tshuaj tiv thaiv zoo heev thiab ua tau raws. Lawv yog cov tsim nyog rau sealing tsis xwm yeem los yog puas flange nto thiab feem ntau yog siv nyob rau hauv tshuaj ua thiab tshuaj daim ntaub ntawv.
5. Retrofit Gaskets:
- Tsim los rov kho cov kev sib txuas uas twb muaj lawm tsis tas yuav tsum tau ua haujlwm lossis hloov kho lub ntsej muag flange. Retrofit gaskets muaj nyob rau hauv ntau yam ntaub ntawv thiab configurations kom haum rau txawv daim ntawv thov.
Cov no tsuas yog qee qhov piv txwv ntawm hom gaskets muaj rau kev sib txuas flanged. Kev xaiv ntawm hom gasket tsim nyog nyob ntawm cov yam ntxwv xws li kev ua haujlwm, qhov kub thiab txias, siab, dej sib xws, thiab flange lub ntsej muag tiav. Nws yog ib qho tseem ceeb uas yuav tau xaiv lub gasket txoj cai rau koj daim ntawv thov tshwj xeeb kom ntseeg tau tias muaj kev ruaj ntseg thiab tsis muaj kev sib khi.
