Sihlalo se-PTFEivalvu yevivane, futsi yatiwa ngekutsi yi-fluoroplastic lining emavalvu lamelana nekugcola, yi-PTFE resin (noma emaphrofayli lacutshungulwa) indlela lebunjiwe (noma lefakwe) kulensimbi noma insimbi yevalve yekucindzeteleka tincenye telubondza lwangaphakatsi (indlela lefanako isebenta kuto tonkhe tinhlobo temikhumbi yekucindzeteleka kanye netinsita tekuphayipha te-valve ye-ufa liner noma) timphahla letihlukile ekumelaneni nemidiya lecinile legugako leyentiwe yaba tinhlobo letehlukene temavalvu kanye nemikhumbi yekucindzetela.
Emavalvu e-PTFE alayiniwe ngenchubo yekugcoka kuto tonkhe tindzawo lapho khona umkhatsi ungafika khona emtimbeni wevalvi, futsi tintfo tekugcoka tivame kwemukela emapulasitiki e-fluorine njenge-FEP (F46) ne-PCTFE (F3), lekungasetjentiswa kumaphayiphi lanetintfo letehlukahlukene te-sulfuric esidi, i-hydrochloric esidi, i-hydrofluoric esidi lonkhe luhlobo, esidi, i-fluoride lecinile kanye naletinye tintfo letiguculako, njll Nomakunjalo, emavalvu lalayiniwe nge fluorine aphansi kwemkhawulo wekushisa (kulungele kuphela tintfo letisemkhatsini wa -50°C na 150°C), futsi lentfo lelayiniwe ingasetjentiswa kutotonkhe tinhlobo temikhumbi yekucindzetela kanye netinsita temaphayiphi. °C ~ 150 °C emkhatsini wetindzaba).
PTFE lined luvivane emavalvu aklanyelwe kujwayela letinye tindzawo letigcobako nge esidi emandla kanye alkali, petroleum, ikhemikhali, kudla kanye naletinye tindzawo letinyenti letikhetsekile sidzingo, lined PTFE ngaphakathi evamile luvivane emavalvu kanye emapuleti valve, ukuze medium kanye valve umzimba kuhlukaniswe i antivalve umphumela, of achiecor.
Imvelo yekusebenta: ingatsatsa sikhundla semtimba wevalve yensimbi ngaphansi kwetimo letijwayelekile, ngekusebenta kwetindleko letisetulu. Ipuleti levivane le-valve ye-butterfly ifakwe ngendlela yebubanti bephayiphi. Emseleni we cylindrical wemtimba we valve ye butterfly, lelipuleti le butterfly lemise njenge disc lijikeleta le axis, futsi i-angle yekujika isemkhatsini wa 0° na 90°.
Kuze ukhone kuvumelana kancono netidzingo tekulawula lokuzenzakalelayo kwesimanje, PTFE lined butterfly valves kungafakwa nge actuators kagesi kanye nemoya, futsi kungalawulwa ngekufaka timphawu tekulawula (4-20mADC noma 1-5VDC) kanye nekuphakelwa kwemandla kwesigaba sinye kute kufezeke timphawu letihlakaniphile (letilawula) kanye nekushintja. Inemsebenti locinile, ivolumu lencane, kukhanya kanye nekushibhile, kusebenta lokutsembekile, kusekela lokulula, umthamo lomkhulu wekujikeleta, ikakhulukati kufanelekile emkhatsini kuyinto viscous, equkethe tinhlayiya, fiber imvelo umcimbi.
Kumelana nekugcola kwe-PTFE lined butterfly valve kuncono kunaloko kwe-PTFE butterfly valve, futsi intengo iyabiza kakhulu.
Ngaphandle kwaloko, Tianjin Tanggu Emanti Seal Valve Co., Ltd. kuyinto tebuchwepheshe phambili elastic situlo valve asekela emabhizinisi, imikhiqizo elastic situlo wafer luvivane valve, lug luvivane valve,Ivalvu yeLisango, ivalvu levivane lephindvwe kabili, ivalvu lephindvwe kabili, ivalvu lebhalansi,wafer emapuleti lamabili ekuhlola ivalvu, Y-Strainer njalonjalo. E-Tianjin Tanggu Water Seal Valve Co., Ltd., siyatigcabha ngekuniketa imikhicito yesigaba sekucala lehlangabetana nemazinga laphakeme embonini. Ngeluhlu lwetfu lolubanti lwemavalvu kanye netimphahla, ungasetsemba kutsi sikunikete sisombululo lesiphelele seluhlelo lwakho lwemanti. Xhumana natsi namuhla kute utfole kabanti ngemikhicito yetfu nekutsi singakusita njani.
