Valve ea polasetiki ke mofuta o sebelisoang haholo oa li-valve, o na le melemo ea ho hanyetsa kutu, boima bo bobebe, ho hanyetsa ho roala, joalo-joalo E sebelisoa haholo lik'hemik'hale, petrochemical, ts'ireletso ea tikoloho le liindasteri tse ling.Se latelang ke histori ea tsoelo-pele ea li-valve tsa polasetiki.
Lilemong tsa bo-1950, ka tsoelo-pele e potlakileng ea indasteri ea lik'hemik'hale, tlhokahalo ea li-valve e ile ea eketseha butle-butle.Nakong ena, lisebelisoa tsa polasetiki li 'nile tsa sebelisoa haholo lefapheng la indasteri, kahoo baenjiniere ba bang ba ile ba qala ho ithuta mokhoa oa ho sebelisa lisebelisoa tsa polasetiki ha ho etsoa li-valve.Li-valve tsa pele tsa polasetiki li ne li etsoa haholo-holo ka thepa ea polyvinyl chloride (PVC), e nang le khanyetso e ntle ea kutu, empa thepa ea eona ea mechine e futsanehile 'me e loketse feela khatello e tlaase le mocheso o tlase o sebetsang tikolohong.
Lilemong tsa bo-1960, ka tsoelo-pele e tsoelang pele ea theknoloji ea polasetiki, polypropylene (PP), polytetrafluoroethylene (PTFE) le lisebelisoa tse ling li ne li sebelisoa ha ho etsoa li-valve tsa polasetiki.Lisebelisoa tsena li na le thepa e ntle ea mochini le ho hanyetsa kutu, 'me li ka ikamahanya le maemo a mangata a fapaneng a ho sebetsa.
Lilemong tsa bo-1970, ka kholo ea theknoloji ea li-valve tsa polasetiki, ho ile ha hlahisoa mefuta e mengata ea li-valve tsa polasetiki tse ncha, tse kang polyvinyl fluoride (PVDF) li-valve, li-valve tsa tšepe tsa khalase, joalo-joalo. Lisebelisoa tsena tse ncha li na le botsitso bo molemo ba lik'hemik'hale le thepa ea mechine, 'me li ka ikamahanya le maemo a thata a mosebetsi.
Qalong ea lekholo la bo21 la lilemo, ka tlhokomeliso e ntseng e eketseha ea ts'ireletso ea tikoloho, litlhoko tsa li-valve li ntse li phahama le ho feta.Nakong ena, lisebelisoa tse ling tse ncha tsa polasetiki li ne li sebelisoa ha ho etsoa li-valve, tse kang polyetherketone (PEEK), polyimide (PI) le lisebelisoa tse ling tsa polasetiki tse sebetsang hantle.Lisebelisoa tsena li na le thepa e ntle ea mochini le ho hanyetsa kutu, 'me li ka kopana le maemo a thata a ho sebetsa.
Ka bokhutšoanyane, ka nts'etsopele ea indasteri ea lik'hemik'hale le tsoelo-pele e tsoelang pele ea theknoloji ea polasetiki, li-valve tsa polasetiki li bone nts'etsopele ea lisebelisoa tsa polasetiki tse sebetsang hantle ho tloha lihlahisoa tsa pele tsa PVC ho fihlela joale, li lula li ntlafatsa ho hanyetsa ha tsona, thepa ea mechine le boholo ba tsona. kopo, ho ba sesebelisoa sa bohlokoa le sa bohlokoa bakeng sa indasteri ea ts'ireletso ea lik'hemik'hale, petrochemical le tikoloho.
