1. Metallic gaskets
Pali mitundu itatu ikuluikulu:
(1) Ma gaskets octagonal ndi oval.Ndioyenera kusindikiza pa flange pamwamba ndi trapezoidal grooves.
(2)Magalasi okhala ndi mbiri ya mano.The conical dzino ripple ndi machined pa osindikiza pamwamba zitsulo lathyathyathya gaskets, oyenera nkhope ya mwamuna ndi mkazi flange.
(3)Magalasi opangira ma lens-oyenera malo osindikizira a lens flange.Ma gaskets achitsulo amapangidwa kuchokera ku chitsulo choyera, chitsulo chakufa chofewa, chitsulo chosapanga dzimbiri, aluminiyamu ndi zinthu zina.
Zofunikira Zapamwamba zili pamakina olondola komanso kuuma kwapamtunda kwa kusindikiza pamwamba pazitsulo zazitsulo, ndipo bawutiyo imakhala ndi mphamvu yayikulu, kotero gasket imagwiritsidwa ntchito kutentha kwambiri komanso ma valve othamanga kwambiri.

2. Zovala zachitsulo za graphite
Nthawi zambiri, amagwiritsidwa ntchito pankhope zachimuna ndi zazikazi komanso zoyenera ma valve okhala ndi kutentha kwambiri komanso kupanikizika.

3. Mapiritsi ozungulira bala
Amapangidwa ndi kusakaniza ndi kupiringa malamba azitsulo zoweyula ndi matepi osindikiza.Pali malamba achitsulo-asibesitosi, malamba achitsulo-polytetrafluoroethylene, malamba achitsulo-osinthika graphite, etc. Kawirikawiri, ma gaskets amagwiritsidwa ntchito pa nkhope zamphongo zamphongo ndi zazikazi komanso zoyenera kutentha kwambiri ndi ma valve opanikizika.

4. Teflon gaskets
Amagwiritsidwa ntchito kwambiri posindikiza lilime-ndi-groove ndipo amapangidwa kuchokera ku PTFE ndi PTFE yokhala ndi ulusi wagalasi.Iwo ndi oyenera amphamvu zikuwononga TV mu kutentha otsika ndi mavuto osiyanasiyana.

5. Magalasi a graphite
Ma gaskets athyathyathya opangidwa kuchokera ku graphite yofewa ndi oyenera kutentha kwambiri komanso media zowononga zamphamvu.

6. Paronite gaskets
Amagwiritsidwa ntchito kumalo osindikizira osalala a flange, nkhope zachimuna ndi zazikazi komanso nkhope za lilime ndi groove.Ubwino wake ndi kukana kwa dzimbiri komanso kukhazikika kwamafuta, pulasitiki yabwino, ndi mphamvu yaying'ono yokakamiza kutsimikizira kusindikiza.Choyipa chake ndi mphamvu yochepa komanso kumamatira kosavuta kumtunda wosindikiza wa flange.Ma gaskets a Paronite amaphatikizapo matabwa a asbestosi, anti-corrosion boardboard asbestos.Nthawi zambiri, ma gaskets amapangidwa kuchokera ku matabwa a asibesitosi, matabwa aasibesito osamva asidi, matabwa aasibesito osamva mafuta, matabwa aasibesito okhala ndi waya wachitsulo ndi zinthu zina.Iwo ntchito sing'anga kuthamanga mavavu kutentha kwambiri.
