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 sameeyay isku dhafka sare ee PTFE iyo EPDM, siddooyinkeena xirmada balabaaliga ee Teflon waxay ku faanaan iska caabin aan caadi ahayn oo ballaaran oo warbaahin ah - biyo iyo saliid ilaa sal, saliid iyo asiidh. Kala duwanaanshiyahani wuxuu hubinayaa in iyadoon loo eegin codsiga, siddooyinkeena xidhidhisku ay bixin karaan waxqabad la isku halayn karo, daadsan- La jaanqaadkooda cabbirada balaaliyeyaasha balastarrada ee u dhexeeya DN50 ilaa DN600 waxay sii hoosta ka xariiqaysaa la qabsigooda nidaamyada tuubooyinka kala duwan, haddii ay isticmaalayaan isku xirka wafer ama flange dhamaadka. Intaa waxaa dheer, hal-abuurnimadu kuma joogsato xulashada alaabta. Naqshadeynta khadka dhexe ee nooca wafer-ka jilicsan ee shaabadeynta balaastiinka wuxuu ku daraa hawlgalka pneumatic si sahlan loo isticmaalo, oo ay weheliso nooca lugaha labajibbaaran waalka balanbaalista badhkeed oo aan lahayn biin loogu talagalay badbaadada iyo cimri dhererka. Injineernimadan fekerka leh waxay tilmaan u tahay sida ay nooga go'an tahay tayada iyo shaqeynta, annagoo hubinayna in siddooyinkeena xirmooyinka balabaaliga ee Teflon ay u taagan yihiin inay yihiin doorashada koowaad ee xirfadlayaasha raadinaya isku halaynta iyo cimri dhererkooda xalalka xiritaanka valve. Iyada oo leh Sansheng Fluorine Plastics, maaha kaliya inaad soo iibsanayso badeecad; waxaad maalgashanaysaa shuraako qiimeeya heer sare iyo hal-abuurnimo si siman.
