Madow/Cagaar PTFE/FPM + EPDM Rubber Valve Kursiga Kursiga Valve Balanbaalista
PTFE + EPDM kuraasta caagga ah ee la isku daray ee ay soo saartay SML ayaa si weyn loogu isticmaalaa dharka, xarunta korantada, petrochemical, kululaynta iyo qaboojiyaha, dawooyinka, dhismaha maraakiibta, birta, warshadaha iftiinka, ilaalinta deegaanka iyo meelaha kale.
Waxqabadka badeecada: caabbinta heerkulka sare, caabbinta acid wanaagsan iyo alkali iyo caabbinta saliidda; leh adkeysi soo kabasho wanaagsan leh, adag oo waara iyada oo aan dareerin.
PTFE+EPDM
Xadhkaha Teflon (PTFE) waxa uu dulsaaraa EPDM kaas oo ku xidhan giraan adag oo phenolic ah oo ku yaala wareegga kursiga ee dibadda. PTFE waxay ku fidsan tahay wejiyada kursiga iyo bannaankaba dhexroorka shaabadda flange, oo si buuxda u daboolaya lakabka elastomer-ka ee EPDM ee kursiga, kaas oo siiya adkeysi loogu xirayo afkoda waalka iyo saxanka xiran.
Heerkulka: -10°C ilaa 150°C.
Budada PTFE (Polytetrafluoroethylene)
PTFE (Teflon) waa polymer-ka ku salaysan fluorocarbon oo caadiyan ah kan ugu adkaysiga badan kiimikaad ee balaastikada oo dhan, iyadoo ilaalinaysa sifooyin heer sare ah oo kuleyl iyo koronto ah. PTFE sidoo kale waxay leedahay iskudhaf hoose oo is jiid jiid ah sidaa darteed waxay ku habboon tahay codsiyo badan oo qulqulka hooseeya.
Walaxdani maaha -wax wasakhaysan oo ay aqbasho FDA ee codsiyada cuntada. Inkasta oo sifooyinka farsamada ee PTFE ay hooseeyaan, marka la barbardhigo balaastikada kale ee la farsameeyey, hantidoodu waxay ahaanayaan kuwo faa'iido leh oo ka badan heerkul ballaaran.
Heerkulka: -38°C ilaa +230°C.
Midabka: cad
Xadhkaha garaaca: 0%

Laga soo dhisay heer sare - isku darka PTFE iyo EPDM, Kursigeena Joogtada ah ee Balanbaalista Valve PTFE waxaa loo habeeyay si uu u bixiyo hufnaanta iyo adkeysi aan la barbar dhigi karin. Astaamaha gaarka ah ee PTFE, oo ay weheliso adkeysiga EPDM, ayaa ka dhigaya kursigan valve mid awood u leh inuu u adkeysto tiro badan oo warbaahin ah - laga bilaabo biyaha iyo saliida gaaska, saliidda saldhigga, iyo xitaa asiidhyada gardarrada ah. Kala duwanaanshiyahani wuxuu hubinayaa in kuraasta valve ay yihiin xalka ugu fiican ee codsiyada dhammaan qaybaha kala duwan, oo ay ku jiraan laakiin aan ku xaddidnayn dhar, koronto, warshado kiimiko ah, nidaamyada kuleylka iyo qaboojinta, daawooyinka, dhisitaanka maraakiibta, farsamaynta birta, warshadaha iftiinka, iyo ilaalinta deegaanka. Kursiga valve waxaa loogu talagalay inuu si aan kala go 'lahayn ugu dhejiyo balaaliyeyaasha balastarrada u dhexeeya DN50 ilaa DN600 ee cabbirka dekedda, taasoo ka dhigaysa doorasho ku habboon labada wafer iyo dhamaadka flange. isku xirka. La qabsigaan, oo ay weheliso iska caabbinta heerkulka sare ee waalka, ayaa ka dhigaysa doorasho ku habboon deegaan halkaas oo waxqabadka sare iyo isku halaynta aan laga gorgortami karin. Waxaa intaa dheer, doorashada u dhaxaysa wafer - nooca khadka dhexe ee jilicsan shaabadeynta balabaliga iyo nooca lugaha oo labanlaab ah waalka balanbaalista badhkii oo aan lahayn biin ayaa bixisa dabacsanaan xagga codsiga iyo rakibida. Muujinta waxtarkeeda, xarunta PTFE iyo EPDM kaliya ma hubiso shaabad adag laakiin sidoo kale waxay wanaajisaa cimriga hawlgalka valve, yaraynta baahida dayactirka joogtada ah ama beddelka. Haddi lagu shaqeeyo xakamaynta biyaha, saliidda, gaaska, ama dhexdhexaad kasta oo caqabad ku ah, Kursigeena Joogtada ah ee Balanbaalista Valve PTFE Kursigu wuxuu ka dhigan yahay meesha ugu sarreysa ee tignoolajiyada xirida waalka, taasoo keenaysa waxqabad aan isbarbardhig lahayn iyo isku halaynta.
