I-valve ene-Teflon iyi-valve esebenzisa i-polytetrafluoroethylene (PTFE, eyaziwa nangokuthi i-Teflon) njengento yokuvala, futhi isetshenziswa kabanzi emikhakheni eminingi ngenxa yezinzuzo zayo eziyingqayizivele zokusebenza. Leli phepha lizokwethula izinzuzo zokusebenza nezinkambu zokusetshenziswa zevalve ene-fluorine enemigqa emine.
Okokuqala, izinzuzo zokusebenza zama-valve e-PTFE
1. Ukumelana nokugqwala okuhle kakhulu: indawo evalekayo yevalve ye-teflon yenziwe ngezinto ezisetshenziswayo ze-polytetrafluoroethylene, ezinokuzinza kwamakhemikhali okuphezulu kakhulu futhi ezingamelana nokugqwala kwemithombo eminingi yamakhemikhali, okuhlanganisa ama-asidi aqinile, i-alkali, izinyibilikisi eziphilayo, njll., ngakho-ke iyasebenza. kahle emkhakheni wezokuthutha abezindaba ezonakalisayo.
2. I-coefficient ephansi yokungqubuzana: I-PTFE ine-coefficient ephansi kakhulu yokungqubuzana (0.05-0.1), okwenza i-valve ye-PTFE ifinyelele ukunyakaza okushelelayo ngesikhathi sokuvula nokuvala, ukunciphisa i-torque yokusebenza nokunciphisa ukusetshenziswa kwamandla kwemishini.
3. I-Anti-viscosity: i-polytetrafluoroethylene ine-anti-viscosity enhle, engavimbela impahla ekunamatheleni endaweni yokuvala futhi inciphise umsebenzi wokugcinwa kwe-valve.
4. Izinga lokushisa elivumelana nezimo: impahla yokuvala ye-PTFE valve lined ingasebenza ku--200 ° C kuya ku-260 ° C isikhathi eside, futhi ingamelana namazinga okushisa aphakeme ngesikhathi esifushane, okwenza i-PTFE valve lined ingaba isetshenziswa ezindaweni ezihlukene zokushisa.
5. Ukusebenza kokuphepha: Ngenxa yokuthi i-valve ene-fluorine enemigqa emine isebenzisa izinto ezingezona ezensimbi njengendawo yokuvala, ngeke ikhiqize izinto eziyingozi ngisho nangaphansi kwezimo ezimbi kakhulu ezifana nokushisa okuphezulu nokucindezela okukhulu, ngakho inokusebenza kokuphepha okuphezulu.
Okwesibili, inkambu yokusetshenziswa kwamavalvu e-PTFE anemigqa
1. Imboni yamakhemikhali: Ama-valve anemigqa ye-PTFE asetshenziswa kakhulu embonini yamakhemikhali, ikakhulukazi emithonjeni eyonakalisayo, izindawo ze-asidi eqinile kanye ne-alkali, ama-valve ane-PTFE afakwe ulayini angaqinisekisa ukusebenza okuphephile kwemishini futhi anciphise izindleko zokuyilungisa.
2. Imboni kaphethiloli: Embonini ye-petroleum, ama-valve analayini we-PTFE avame ukusetshenziselwa ukuthutha uwoyela, igesi yemvelo kanye nezinye imidiya, futhi ukumelana kwayo nokugqwala okuhle kakhulu nokusebenza kokuvala kwenza ama-valve anemigqa ye-PTFE abe amavalvu athandwayo embonini ye-petroleum.
3. Imboni yezemithi: Imboni yemithi inezidingo eziphezulu zokuhlanzeka nokuphepha kwemishini, futhi i-valve ye-tetrafluorolined ihlangabezana nalezi zidingo, ngakho-ke isetshenziswa kabanzi embonini yezemithi.
4. Imboni ye-elekthronikhi: Ukusetshenziswa kwamavalve anemigqa ye-PTFE embonini ye-elekthronikhi kubonakala ikakhulukazi ekudluliseni nasekulawuleni amagesi ahlanzekile noketshezi, futhi ukusebenza kwawo okuhle kakhulu kungaqinisekisa ukusebenza okuzinzile kwemishini kagesi.
6. Imbonini yokudla: Ngenxa yezakhiwo ezinhle zokulwa ne-viscosity kanye ne-anti-corrosion yama-valve anemigqa ye-PTFE, nawo asetshenziswe kabanzi embonini yokudla, njengokusebenza okuhle kakhulu ekudluliseni imidiya ephezulu ye-viscosity efana isiraphu nejusi.
Kafushane, amavalvu anemigqa ye-PTFE asetshenziswe kabanzi emikhakheni eminingi ngenxa yezinzuzo zawo zokusebenza ezinhle kakhulu. Ngokuthuthuka okuqhubekayo kwesayensi nobuchwepheshe, inkambu yokusetshenziswa kwamavalvu anemigqa ye-PTFE izonwetshwa ngokuzayo.
