Teflon lined valve ke valve e sebelisang polytetrafluoroethylene (PTFE, e tsejoang hape e le Teflon) e le thepa ea ho tiisa, 'me e sebelisoa haholo libakeng tse ngata ka lebaka la melemo ea eona e ikhethang ea ts'ebetso. Pampiri ena e tla hlahisa melemo ea ts'ebetso le likarolo tsa ts'ebeliso ea valve e nang le fluorine lined.
Taba ea pele, melemo ea ts'ebetso ea li-valve tsa PTFE
1. Ho hanyetsa kutu e ntle ka ho fetisisa: sebaka se tiisang sa valve ea teflon se entsoe ka thepa ea polytetrafluoroethylene, e nang le botsitso bo phahameng ka ho fetisisa ba lik'hemik'hale 'me e khona ho hanela ho bola ha lik'hemik'hale tse ngata tsa lik'hemik'hale, ho akarelletsa le li-acids tse matla, alkali, li-solvents, joalo-joalo. hantle tšimong ea lipalangoang tse senyang tsa media.
2. Coefficient e fokolang ea likhohlano: PTFE e na le coefficient e fokolang haholo ea likhohlano (0.05-0.1), e etsang hore valve ea PTFE e khone ho finyella motsamao o boreleli nakong ea ho bula le ho koala, ho fokotsa torque ea ts'ebetso le ho fokotsa tšebeliso ea matla ea thepa.
3. Anti-viscosity: polytetrafluoroethylene e na le anti-viscosity e ntle, e ka thibelang thepa hore e se ke ea khomarela holim'a ho tiisa le ho fokotsa mosebetsi oa tlhokomelo ea valve.
4. Ho ikamahanya le maemo a mocheso: thepa ea ho tiisa ea valve e nang le PTFE e ka sebetsa ho tloha -200 ° C ho ea ho 260 ° C ka nako e telele, 'me e ka mamella mocheso o phahameng ka nako e khutšoanyane, e leng se etsang hore valve e nang le PTFE e be teng. e sebelisoa libakeng tse fapaneng tsa mocheso.
5. Ts'ebetso ea ts'ireletso: Hobane valve e nang le lisebelisoa tse 'nè tsa fluorine e sebelisa lisebelisoa tse se nang tšepe e le sebaka sa ho tiisa, e ke ke ea hlahisa lintho tse kotsi esita le tlas'a maemo a feteletseng a kang mocheso o phahameng le khatello e phahameng, kahoo e na le ts'ebetso e phahameng ea tšireletso.
Ea bobeli, tšimo ea ts'ebeliso ea li-valve tsa PTFE tse nang le mela
1. Indasteri ea lik'hemik'hale: Li-valve tse nang le PTFE li sebelisoa haholo indastering ea lik'hemik'hale, haholo-holo mecheng ea litaba e senyang, libaka tse matla tsa acid le alkali, li-valve tse nang le PTFE li ka netefatsa ts'ebetso e sireletsehileng ea lisebelisoa le ho fokotsa litšenyehelo tsa tlhokomelo.
2. Indasteri ea peterole: Lefapheng la peterole, li-valve tsa PTFE li atisa ho sebelisoa ho tsamaisa oli, khase ea tlhaho le mecha e meng ea litaba, 'me ho hanyetsa ha eona ho matla ha kutu le ts'ebetso ea ho tiisa ho etsa hore PTFE li-valve li be le valve e ratoang indastering ea peterole.
3. Indasteri ea meriana: Indasteri ea meriana e na le litlhoko tse phahameng bakeng sa bohloeki le polokeho ea thepa, 'me valve ea tetrafluorolined e finyella litlhoko tsena feela, kahoo e sebelisoa haholo indastering ea meriana.
4. Indasteri ea elektronike: Tšebeliso ea li-valve tsa PTFE tse nang le li-valve indastering ea elektronike e bonahala haholo-holo ho fetisetsoang le ho laola likhase tse phahameng tsa bohloeki le metsi, 'me ts'ebetso ea eona e babatsehang e ka netefatsa ts'ebetso e tsitsitseng ea lisebelisoa tsa elektronike.
6. Indasteri ea lijo: Ka lebaka la thepa e ntle ea anti-viscosity le anti-corrosion ea PTFE lined valves, li boetse li sebelisoa haholo indastering ea lijo, tse kang ts'ebetso e babatsehang ea ho tsamaisa mecha ea litaba e phahameng ea viscosity e kang sirapo le lero.
Ka kakaretso, li-valve tsa PTFE li 'nile tsa sebelisoa haholo libakeng tse ngata ka lebaka la melemo ea tsona e babatsehang ea tshebetso. Ka nts'etsopele e tsoelang pele ea mahlale le thekenoloji, sebaka sa ts'ebeliso ea li-valve tsa lined tsa PTFE se tla atolosoa le ho feta nakong e tlang.
