Ivalve enemigca yeTeflon yivalve esebenzisa i-polytetrafluoroethylene (PTFE, eyaziwa ngokuba yiTeflon) njengento yokutywina, kwaye isetyenziswa ngokubanzi kwiindawo ezininzi ngenxa yeenzuzo zayo zokusebenza ezizodwa. Eli phepha liza kwazisa iingenelo zokusebenza kunye nemimandla yokusetyenziswa kwevalve ene-fluorine enemigca emine.
Okokuqala, iingenelo zokusebenza kweevalvu ze-PTFE
1. Ukumelana ne-corrosion egqwesileyo: indawo yokutywina yevalve ye-teflon yenziwe nge-polytetrafluoroethylene impahla, enozinzo oluphezulu kakhulu lweekhemikhali kwaye inokumelana nokubola kwemithombo yeendaba ezininzi zeekhemikhali, kubandakanywa i-acids eqinile, i-alkali, i-solvents ye-organic, njl. kakuhle kwintsimi yothutho lweendaba ezonakalisayo.
2. I-coefficient ephantsi ye-friction: I-PTFE ine-coefficient ephantsi kakhulu ye-friction (0.05-0.1), eyenza i-valve ye-PTFE ikwazi ukufezekisa ukuhamba kakuhle ngexesha lokuvula nokuvalwa, ukunciphisa i-torque yokusebenza kunye nokunciphisa ukusetyenziswa kwamandla kwezixhobo.
3. I-Anti-viscosity: i-polytetrafluoroethylene ine-anti-viscosity enhle, enokuthintela izinto eziphathekayo ekunamatheleni kwindawo yokutywina kunye nokunciphisa umsebenzi wokugcinwa kwevalve.
4. Ukulungelelaniswa kobushushu: izinto zokutywina ze-PTFE ivalve enemigca ingasebenza kuluhlu lwe-200 ° C ukuya kwi-260 ° C ixesha elide, kwaye inokumelana namaqondo okushisa aphezulu ngexesha elifutshane, okwenza ukuba i-valve ye-PTFE ifakwe. isetyenziswa kwiindawo ezahlukeneyo zobushushu.
5. Ukusebenza koKhuseleko: Ngenxa yokuba i-valve ene-fluorine enemigca emine isebenzisa izinto ezingezona zetsimbi njengendawo yokutywinwa, ayiyi kuvelisa izinto ezinobungozi naphantsi kweemeko ezinzima ezifana nokushisa okuphezulu kunye noxinzelelo oluphezulu, ngoko lunokhuseleko oluphezulu.
Okwesibini, insimu yesicelo yee-valve ze-PTFE ezinemigca
1. Ishishini lemichiza: I-PTFE i-valve ene-lined isetyenziswa ngokubanzi kwishishini lemichiza, ngakumbi kwimithombo yeendaba etshabalalisayo, i-asidi eqinile kunye neendawo ze-alkali, i-PTFE i-valve ene-alkali inokuqinisekisa ukusebenza ngokukhuselekileyo kwezixhobo kunye nokunciphisa iindleko zokugcina.
2. Ishishini lepetroleum: Kushishino lwepetroleum, i-PTFE iivalvu ezinemigca zihlala zisetyenziselwa ukuthutha ioyile, igesi yendalo kunye nezinye izinto zosasazo, kwaye ukumelana kwayo nokugqwesa okugqwesileyo kunye nokusebenza kokutywinwa kwenza i-PTFE iivalve ezinemigca ibe yivalve ekhethwayo kushishino lwepetroleum.
3. Imboni yamachiza: Ishishini lamachiza lineemfuno eziphezulu zokucoceka kunye nokhuseleko lwezixhobo, kwaye i-valve ye-tetrafluorolined ihlangabezana nje nezi mfuno, ngoko isetyenziswa ngokubanzi kwishishini lamachiza.
4. Ishishini le-elektroniki: Ukusetyenziswa kwe-PTFE i-valve ene-lined kwi-electronic industry ibonakaliswe ngokukodwa ekugqithiseni nasekulawuleni iigesi ezicocekileyo kunye nolwelo, kunye nokusebenza kwayo okugqwesileyo kunokuqinisekisa ukusebenza okuzinzileyo kwezixhobo zombane.
6. Ishishini lokutya: Ngenxa yezinto ezintle ezichasene ne-viscosity kunye ne-anti-corrosion ye-PTFE i-valve enemigca, nayo isetyenziswe ngokubanzi kwishishini lokutya, njengomsebenzi ogqwesileyo wokuhambisa imidiya ephezulu ye-viscosity efana nesiraphu kunye nejusi.
Isishwankathelo, iivalvu ezinemigca ye-PTFE zisetyenziswe ngokubanzi kwiindawo ezininzi ngenxa yeenzuzo zazo zokusebenza ezibalaseleyo. Ngophuhliso oluqhubekayo lwesayensi kunye nobuchwepheshe, intsimi yesicelo se-PTFE i-valve ene-lined iya kwandiswa ngakumbi kwixesha elizayo.
