Mefuta e meholo ea li-gasket tsa flange
Li-gasket tse seng tsa tšepe
Lisebelisoa tse tloaelehileng: rabara, polytetrafluoroethylene (PTFE), faeba e seng ea asbestos (asbestos ea rabara).
Tšebeliso le likarolo tsa bohlokoa:
Li-gasket tsa rabara tsa asbestos e ne e le khetho e tloaelehileng, li sebelisoa haholo metsing, moeeng, mouoane, asiti le mecha ea litaba ea alkali.
Bakeng sa maemo a sa senyeheng ke mafome, digasket tsa PTFE di na le botsitso bo botle ba dikhemikhale.
Li-gasket tsa semi-metallic
Thepa e tloaelehileng: Lebanta la tšepe + graphite/asbestos/lebanta le tletseng PTFE (mofuta oa leqeba), karolo e ka hare e se nang tšepe e koahetsoeng ka tšepe, gasket e kopaneng ea graphite e tenyetsehang.
Tšebeliso le likarolo tsa bohlokoa:
Ho kopanya matla a tšepe le ho tenyetseha ha e seng tšepe maemong a mosebetsi a mocheso o phahameng, khatello e phahameng le a feto-fetohang. Har'a tsona, li-gasket tsa maqeba a tšepe ke khetho e kholo indastering ea petrochemical, lik'hemik'hale le tse ling.
Bakeng sa litlhoko tse matla tsa ho tiisa, tse kang li-gasket tsa tšepe tse nang le serrated/wavy ring, li sebelisoa liphaepheng kapa lijaneng tsa khatello tse nang le khatello le mocheso o phahameng.
Li-gasket tsa tšepe
Lisebelisoa tse tloaelehileng: tšepe e bonolo, tšepe e sa ruseng, koporo, motsoako oa Monel.
Lisebelisoa le likarolo tse ka sehloohong:
Maemo a feteletseng: a sebediswa mecheng ya mocheso o phahameng, kgatello e phahameng le e senyang haholo.
Li fana ka ts'ebetso e ntle ea ho tiisa empa li na le litlhoko tse phahameng haholo bakeng sa ho nepahala ha ts'ebetso ea bokaholimo ba ho tiisa le ho kenya ha flange, 'me li theko e boima.
Ha ho khethoa li-gasket, lintlha tse ngata li hloka ho nahanoa ka botlalo. Ntlha ea bohlokoa e ka sehloohong ke lintlha tse 'ne tsa bohlokoa: "mahareng, khatello, mocheso, le flange“.
Thepa e mahareng: Bakeng sa di-media tse senyang (tse kang di-acid le di-alkali), thepa ya gasket e lokela ho ba e sa senyeheng.
Khatello le mocheso o sebetsang: Maemong a mocheso o phahameng le a khatello e phahameng, ho lokela ho khethoa li-gasket tsa tšepe kapa tse halofo ea tšepe tse ka mamellang mocheso le khatello.
Mofuta oa bokaholimo ba ho koala Flange: Libaka tse fapaneng tsa flange (tse kang RF ea sefahleho se phahamisitsoeng, MFM ea sefahleho sa monna le mosali, TG ea sefahleho sa leleme le groove) li tlameha ho tsamaellana le mefuta e itseng ea gasket.
Mabaka a mang: Ho thothomela, ho feto-fetoha khafetsa ha mocheso le khatello, tlhoko ea ho qhaqhoa khafetsa, le tekanyetso ea litšenyehelo le tsona li lokela ho nahanoa.
Ka kakaretso,
Bakeng sa kgatello e tlase le mecha e tloaelehileng (metsi, moya, mouoane o tlase): Di-gasket tse seng tsa tshepe, tse kang rabara kapa di-gasket tsa PTFE, di a ratwa ka lebaka la ho ba le ditjeo tse ngata.
Bakeng sa khatello e mahareng ho isa ho e phahameng, mocheso o phahameng kapa maemo a rarahaneng a mosebetsi (liphaephe indastering ea peterole, lik'hemik'hale le motlakase): Li-gasket tse se nang tšepe, haholo-holo li-gasket tse nang le maqeba a tšepe, ke khetho e tloaelehileng le e tšepahalang ka ho fetisisa.
Bakeng sa mocheso o phahameng haholo le khatello kapa maemo a matla a senyang: Li-gasket tsa tšepe (tse kang li-gasket tse kobehileng kapa tse leketlileng) li lokela ho nahanoa, empa ho bohlokoa ho netefatsa hore lia tšoana hantle le ho kenngoa hantle ha li-flange.
