Isihlalo se-PTFEuvemvane valve, eyaziwa nangokuthi ama-fluoroplastic lining-resistant corrosion valves, iyindlela ye-PTFE resin (noma amaphrofayili acutshunguliwe) abunjiwe (noma afakwe ngaphakathi) ezingxenyeni zokucindezela zensimbi noma zensimbi zodonga lwangaphakathi (indlela efanayo iyasebenza kuzo zonke izinhlobo zemikhumbi yokucindezela futhi amapayipi izesekeli ulayini) noma ingaphandle lezingxenye zangaphakathi ze-valve, kusetshenziswa izici zalo ezihlukile ukumelana nemithombo yezindaba egqwalayo eqinile eyenziwe yaba izinhlobo ezahlukene zamavalvu nemikhumbi yokucindezela.
Amavalvu e-PTFE ahlanganiswe nenqubo yolayini kuzo zonke izindawo lapho okuphakathi kungafinyelela khona emzimbeni we-valve, futhi impahla yolwelwesi ngokuvamile isebenzisa amapulasitiki e-fluorine afana ne-FEP (F46) ne-PCTFE (F3), angasetshenziswa kumapayipi anezingxube ezihlukahlukene. ye-sulfuric acid, i-hydrochloric acid, i-hydrofluoric acid, i-aqua regia nazo zonke izinhlobo zama-asidi aphilayo, ama-acids aqinile, i-fluoride eqinile nezinye izinto ezilimazayo, njll. Kodwa-ke, ama-valve ane-fluorine ane-fluorine angaphansi komkhawulo wezinga lokushisa (ilungele kuphela imimoya phakathi -50 ℃ kanye ne-150 ℃), futhi impahla yolwelwesi ingasetshenziswa kuzo zonke izinhlobo zemikhumbi yokucindezela kanye nezinsiza zamapayipi. ℃ ~ 150 ℃ phakathi kwabezindaba).
PTFE ulayini uvemvane valve yakhelwe ukuzivumelanisa kwezinye izindawo ezonakalisayo nge acid eqinile ne-alkali, uphethiloli, amakhemikhali, ukudla nezinye izindawo eziningi ezikhethekile zesidingo, afakwe PTFE ngaphakathi ezivamile uvemvane valves kanye valve amapuleti, ukuze medium kanye valve. umzimba uhlukaniswe, ukufeza umphumela we-anticorrosion.
Indawo yokusebenza: ingangena esikhundleni somzimba we-valve yensimbi engagqwali ngaphansi kwezimo ezivamile, ngokusebenza kwezindleko eziphezulu. Ipuleti uvemvane uvemvane lifakwe ohlangothini lobubanzi bepayipi. Kusiteshi esiyisilinda somzimba we-valve uvemvane, ipuleti levemvane elimise okwediski lizungeza i-eksisi, futhi i-engeli yokuzungeza iphakathi kuka-0° no-90°.
Ukuze uvumelane kangcono nezidingo zokulawula okuzenzakalelayo kwesimanje, amavalvu ovemvane anemigqa ye-PTFE angafakwa ama-actuator kagesi nomoya, futhi angalawulwa ngokufaka amasiginali okulawula (4-20mADC noma 1-5VDC) kanye nokuphakelwa kwamandla kwesigaba esisodwa bona izinhlobo ezihlakaniphile (ezilawulayo) nezishintshayo. Inomsebenzi oqinile, umthamo omncane, ukukhanya nokushibhile, ukusebenza okuthembekile, ukusekela okulula, umthamo omkhulu wokujikeleza, ofaneleka ngokukhethekile okuphakathi kuyi-viscous, equkethe izinhlayiya, i-fiber nature of the event.
Ukumelana nokugqwala kwe-PTFE valve uvemvane olayini kungcono kunaleyo ye-PTFE butterfly valve, futhi intengo ibiza kakhulu.
Ngaphandle kwalokho, i-Tianjin Tanggu Water Seal Valve Co., Ltd. iyi-valve yesihlalo esinwebekayo esezingeni eliphezulu esekela amabhizinisi, imikhiqizo i-elastic seat wafer butterfly valve, i-lug butterfly valve,Ivalve yesango, i-valve yevemvane ene-flange ephindwe kabili, i-valve ye-butterfly ene-flange ephindwe kabili, i-balance valve,i-valve yokuhlola ipuleti eyisicwecwana esiyibili, Y-Strainer nokunye. E-Tianjin Tanggu Water Seal Valve Co., Ltd., siyaziqhenya ngokuhlinzeka ngemikhiqizo esezingeni eliphezulu ehlangabezana namazinga aphezulu embonini. Ngohlu lwethu olubanzi lwama-valve nokufakwa, ungasethemba ukuthi sizokunikeza isisombululo esiphelele sohlelo lwakho lwamanzi. Xhumana nathi namuhla ukuze ufunde kabanzi mayelana nemikhiqizo yethu nokuthi singakusiza kanjani.
