1. Ama-gaskets ensimbi
Kunezinhlobo ezintathu eziyinhloko:
(1)Ama-octagonal nama-oval gaskets.Zifanele indawo yokuvalwa kwe-flange ene-trapezoidal grooves.
(2)Ama-Gaskets anephrofayili yamazinyo.I-conical tooth ripple yenziwa ngomshini endaweni evalekayo yama-gaskets ayisicaba ensimbi, afanele ubuso be-flange besilisa nabesifazane.
(3)Ama-lens gaskets-afanele izindawo zokuvala ze-lens flange.Ama-gaskets ensimbi enziwe ngensimbi emsulwa, insimbi ethambile efile, insimbi engagqwali, i-aluminium nezinye izinto.
Izimfuneko Eziphakeme zikukunemba komshini kanye nobukhulu obungaphezulu kwendawo yokuvala yama-gaskets ensimbi, futhi ibhawodi linamandla amakhulu okucindezela, ngakho-ke i-gasket isetshenziselwa izinga lokushisa eliphezulu kanye nama-valve omfutho ophezulu.

2. Izinsimbi ze-graphite gaskets
Ngokuvamile, asetshenziselwa ubuso be-flange owesilisa nowesifazane futhi afanele ama-valve anezinga lokushisa eliphezulu nokucindezela.

3. Ama-gaskets amanxeba okuvunguza
Akhiwa ngokuxuba nokusonta amabhande ensimbi amagagasi kanye namatheyipu okuvala.Kukhona amabhande ensimbi-i-asbestos, amabhande ensimbi-polytetrafluoroethylene, amabhande ensimbi-i-graphite eguquguqukayo, njll. Ngokuvamile, ama-gaskets asetshenziselwa ubuso be-flange besilisa nabesifazane futhi afanele ukushisa okuphezulu kanye nama-valve okucindezela okuphakathi.

4. Teflon gaskets
Asetshenziselwa kakhulu izindawo zokuvala ulimi-ne-groove futhi zenziwe nge-PTFE ne-PTFE ngemicu yengilazi.Zifanele imidiya eqinile egqwalayo ekushiseni okuphansi nezingcindezi ezihlukahlukene.

5. I-graphite gaskets
Ama-gaskets ayisicaba enziwe nge-graphite ethambile afanele izinga lokushisa eliphezulu kanye nemidiya eqinile edlayo.

6. I-Paronite gaskets
Zisebenza ezindaweni zokuvala ezibushelelezi ze-flange, ubuso be-flange besilisa nabesifazane kanye nobuso be-flange be-limi-and-groove.Izinzuzo ukumelana nokugqwala okuhle nokuzinza kokushisa, ipulasitiki enhle, namandla amancane okucindezela ukuqinisekisa ukuvala.Okubi amandla aphansi nokunamathela kalula endaweni yokuvala i-flange.Ama-gaskets e-Paronite ahlanganisa amabhodi e-asbestos, amabhodi e-asbestos e-anti-corrosion.Ngokuvamile, ama-gaskets enziwa ngamabhodi e-asbestos, amabhodi e-asbestos angamelana ne-asidi, amabhodi e-asbestos amelana nowoyela, amabhodi e-asbestos anezintambo zensimbi nezinye izinto.Asetshenziselwa ama-valve okucindezela okuphakathi ekushiseni okuphezulu.
