Li-valve li arotsoe ka boholo ba "khatello" / mocheso / thepa / khokahano / ts'ebetso Ho bola ha lik'hemik'hale tsa tšepe ho ipapisitse le mocheso, mojaro oa mochini oa likarolo tse hohlang, botsitso ba li-sulfide tse fumanehang linthong tse tlotsang le ho hanyetsa acid, nako ea ho kopana le mahareng le phello e susumetsang ea tšepe ts'ebetsong ea nitriding, sekhahla sa phetoho ea limolek'hule tsa lintho tse bolang ho litšepe, joalo-joalo. Kaha kutu e etsahala ka tšebelisano e iketsahallang pakeng tsa litšepe le tikoloho e potolohileng, mokhoa oa ho arola litšepe tikolohong e potolohileng kapa ho sebelisa lisebelisoa tse ngata tsa maiketsetso tse seng tsa tšepe e se e le taba e tloaelehileng. 2. Hoa tsebahala hore tšenyo ea tšepe ea tšepe e na le tšusumetso e kholo bophelong, ho tšepahala le bophelo ba tšebeletso ea li-valve. Ketso ea li-agent tsa mechine le tse senyang ka tšepe li eketsa haholo palo eohle ea ho apara holim'a sefahleho sa ho kopana. Valve nakong ea ts'ebetso, likhohlano tsa bokaholimo ba kakaretso ea ho roala. Nakong ea ts'ebetso ea li-valve, libaka tse khohlano lia khema le ho senyeha ka lebaka la ts'ebetso e ts'oanang ea mochini le litšebelisano tsa lik'hemik'hale kapa tsa electrochemical lipakeng tsa tšepe le tikoloho. Bakeng sa valve, maemo a eona a leholimo a sebetsang lipeipi a rarahane; Ho ba teng ha hydrogen sulfide, carbon dioxide le li-acids tse ling tsa organic ka oli, khase ea tlhaho le metsi a polokelo ho eketsa matla a senyang a holim'a tšepe, kahoo a lahleheloa ke matla a ho sebetsa ka potlako. 3, ka lebaka la ho bola ha lik'hemik'hale tsa tšepe ho ipapisitse le mocheso, moroalo oa likarolo tsa likhohlano, lisebelisoa tse tlotsang tse nang le sulfide le botsitso ba eona ba ho hanyetsa acid le nako ea ho ikopanya le tšepe ts'ebetsong ea nitriding ea ts'ebetso ea catalytic, ho bola ha limolek'hule tsa thepa. ka lebelo la ho fetola tšepe joalo-joalo. Ka hona, mokhoa oa anticorrosion oa valve ea tšepe (kapa tekanyo) le ts'ebeliso ea li-valve tsa thepa ea maiketsetso e fetohile e 'ngoe ea lihlooho tsa lipatlisiso tsa indasteri ea li-valve. 4, valve ea tšepe ea anticorrosion, e ka utloisisoa e le valve ea tšepe e koahetsoeng ho sireletsa boemo ba lera le sireletsang ho senya (joalo ka pente, pente, lisebelisoa tsa ho tlotsa, joalo-joalo), e le hore valve e ka etsoa, polokelo, lipalangoang. kapa ts'ebetsong eohle ea ts'ebeliso ea eona ha e rusoe. 5, mokhoa oa anticorrosion oa tšepe o itšetlehile ka nako e hlokahalang ea tšireletso, maemo a lipalangoang le a ho boloka, litšobotsi tsa sebopeho sa valve le thepa, ehlile, ho nahana ka phello ea moruo ea ho tlosa anticorrosion. Sehlopha sa li-valve ho ea ka bophara / khatello / mocheso / thepa / mokhoa oa ho kopanya / mokhoa oa ts'ebetso Ho arola li-valve ho ea ka bophara ba lebitso 1, "valve e nyenyane ea bophara" bophara ba lebitso la DN≤40mm 2, "valve ea bophara bo bohareng" bophara ba lebitso la DN50-300mm 3, "valve e kholo ea bophara ba" "Belofo e kholo ea bophara" DN350-1200mm valve 4, "valve e kholo ea bophara ba" "valve e kholo" ka lebitso la bophara DN≥1400mm Li-valve li khetholloa e le li-valve tsa boholo ba lebitso 1, "valve e nyenyane ea caliber" bophara ba lebitso la DN≤40mm valve 2, "bohareng". caliber valve" bophara ba lebitso la DN50-300mm valve 3, "valve e kholo ea caliber" ka lebitso la bophara DN350-1200mm valve 4, "valve e kholo ea bophara ba" bophara ba lebitso la DN≥1400mm Sehlopha sa li-valve tsa khatello ea lebitso 1, "vacuum valve" khatello ea ho sebetsa e tlase ho feta sepakapaka se tloaelehileng sa khatello ea sepakapaka 2, "valve ea khatello e tlase" khatello ea lebitso PN≤ 1.6mpa valve 3, "valve ea khatello e mahareng" khatello ea lebitso PN2.5-6.4mpa valve 4, "valve e phahameng ea khatello" khatello ea lebitso PN10.0-80.0mpa valve 5, "valve e phahameng ea khatello e phahameng" ka lebitso la khatello ea maikutlo PN≥100MPA valve Ho ea ka karolo ea 1 ea mocheso oa mocheso o phahameng, "valve e phahameng ea mocheso" T > 450 ℃ valve 2, "valve ea mocheso o bohareng" 120℃≤ T ≤450℃ valve 3, "valve e tloaelehileng ea mocheso" -40 ℃≤ T ≤120℃ valve 4, "valve e tlaase ea mocheso" -100℃≤ T ≤-40℃ valve 5, "** mocheso valve" T
