Liaparo tsa rona tse ngata li na le lifaha tse ntle matsohong a matsoho
Li-valve tse khethehileng tsa thepa li bua ka li-valve tse entsoeng ka thepa e khethehileng ho finyella litšobotsi tsa mocheso o phahameng oa ho hanyetsa, ho hanyetsa kutu, ho hanyetsa ho apara, le maemo a mang a ho sebetsa. Ka lebaka la karolo ea bohlokoa e phethoang ke li-valve tšimong ea indasteri, khetho ea lisebelisoa tsa li-valve e ama ka ho toba bophelo ba tšebeletso le ts'ebetso e tloaelehileng ea li-valve. Ho na le mefuta e fapaneng ea li-valve tse khethehileng tsa thepa, tse arotsoeng ka thepa ea 'mele oa li-valve:
(1) Li-valve tsa thepa e seng tsa tšepe tse kang li-valve tsa ceramic, li-valve tsa fiberglass le li-valve tsa polasetiki.
(2) Li-valve tsa tšepe tse kang li-valve tsa koporo, li-valve tsa alloy alloy, li-valve tsa alloy lead, li-valve tsa Monel alloy, li-valve tsa tšepe tse tlaase, le li-valve tse phahameng tsa tšepe.

Li-valve tse khethehileng tse hlahisoang ke BOLON li entsoe ka thepa ea tšepe. E arotsoe ka morero le ts'ebetso ka tsela e latelang:
(1) E sebelisetsoa ho khaola kapa ho hokahanya phallo ea mecha ea litaba. Ho kenyeletsoa li-valve tsa heke, li-valve tsa globe, li-valve tsa diaphragm, li-valve tsa bolo, li-valve tsa plug, li-valve tsa serurubele, li-plunger valves, li-valve tsa bolo, li-valve tsa lisebelisoa tsa nale, joalo-joalo.
(2) E sebelisetsoa ho laola sekhahla sa phallo, khatello, joalo-joalo ea bohareng. Ho kenyelletsa li-valve tse laolang, li-valve tsa throttle, li-valve tse fokotsang khatello, joalo-joalo.
(3) E sebelisetsoa ho thibela mecha ea litaba hore e khutle. Ho kenyeletsoa li-valve tsa cheke tsa meaho e fapaneng.
(4) E sebelisoa bakeng sa ho arola, ho aba, kapa ho kopanya mecha ea litaba. Ho kenyelletsa li-valve tsa kabo le li-valve tsa drain tsa meaho e fapaneng.
Mokhoa oa ho khetha thepa e nepahetseng ea li-valve
Ho khetha lisebelisoa tse loketseng tsa li-valve ho hloka ho nahanoa ka lintlha tse fapaneng tse kang tikoloho ea ts'ebetso, sebaka sa ho sebetsa, mocheso oa ts'ebetso le khatello. Ka kakaretso, ha u khetha lisebelisoa tse khethehileng tsa valve, lintlha tse latelang li lokela ho hlokomeloa:
1. Khetho e itšetlehileng ka mokhoa oa ho sebetsa: Lisebelisoa tse fapaneng tsa li-valve li ka mamella mecha ea litaba e fapaneng, 'me lisebelisoa tse lumellanang li lokela ho khethoa ho ea ka thepa ea mecha ea litaba.
2. Khetho e itšetlehileng ka mocheso oa ho sebetsa le khatello: Hoa hlokahala ho khetha lisebelisoa tsa li-valve tse thehiloeng linthong tse kang mocheso oa ho sebetsa le khatello ho tiisa hore valve e ka sebetsa ka mokhoa o tloaelehileng.
3. Ho nahanoa ka lintlha tsa moruo: Lisebelisoa tse khethehileng tsa li-valve li na le litheko tse fapaneng, 'me hoa hlokahala ho hlahloba ka botlalo lintlha tsa moruo ho khetha lisebelisoa tse loketseng.
Litlhokomelo tsa ho sebelisa lisebelisoa tse khethehileng tsa valve
1. Ha u sebelisa, hoa hlokahala ho qoba tšusumetso ea mojaro le ho sisinyeha, le ho qoba ho thulana ka holim'a thepa;
2. Mekhoa e tloaelehileng ea ts'ebetso e lokela ho lateloa nakong ea tlhokomelo le tlhokomelo ho qoba tšebeliso ea mecha ea litaba e senyang e kang li-acids le alkalis;
3. Pele o sebelisa lisebelisoa tse khethehileng tsa li-valve, tlhahlobo e felletseng le tlhahlobo ea boleng lia hlokahala ho etsa bonnete ba hore lisebelisoa li fihlela litlhoko;
4. Nakong ea tšebeliso, hoa hlokahala ho hlahloba kamehla boemo le katleho ea lisebelisoa tse khethehileng tsa valve.
Lisebelisoa tse khethehileng tsa li-valve li bohlokoa bakeng sa ho boloka ts'ebetso e tloaelehileng ea li-valve, 'me ho bohlokoa ho khetha lisebelisoa tse khethehileng tsa li-valve bakeng sa ho ntlafatsa bophelo ba tšebeletso ea valve le polokeho. Ha u sebelisa lisebelisoa tse khethehileng tsa valve, ho hlokahala hore u ele hloko ts'ebetso e sireletsehileng le tlhokomelo e utloahalang.
Lisebelisoa tsa motsoako oa BOLON li kenyelletsa tšepe e sa hloekang ea duplex, tšepe e sa hloekang ea super duplex, alloy 20, Monel alloy, Hastelloy alloy, chromium cobalt alloy, pure titanium, titanium alloy, 904L, zirconium, uranium, 254 SMO, 6Moly, 6Moly, 6Moly, joalo-joalo. Re amohela basebelisi ba ho qetela le lik'hamphani tsa boenjiniere, haholo-holo bahlahisi ba lik'hemik'hale, polasetiki le polymer, baetsi ba lik'hemik'hale tse ntle, lijenereithara tsa petrochemical le khase ea tlhaho, hammoho le basebetsi ba setsi sa nyutlelie le baetsi ba lisebelisoa tsa likepe, tsa metsing le tsa metsing, ho botsa ka mohala kapa imeile.
