Mpando Wakuda Wakuda/Wobiriwira PTFE/ FPM +EPDM Mpira Wavavu wa Gulugufe
PTFE + EPDM ophatikizana mphira valavu mipando opangidwa ndi SML chimagwiritsidwa ntchito nsalu, magetsi, petrochemical, Kutentha ndi refrigeration, mankhwala, shipbuilding, zitsulo, makampani kuwala, kuteteza chilengedwe ndi zina.
Kuchita kwa mankhwala: kukana kutentha kwakukulu, kukana kwa asidi wabwino ndi alkali ndi kukana mafuta; yokhala ndi mphamvu zobwereranso bwino, zolimba komanso zolimba popanda kutayikira.
PTFE+ EPDM
Liner ya Teflon (PTFE) imakuta EPDM yomwe imamangiriridwa ku mphete yolimba ya phenolic pamphepete mwa mpando wakunja. The PTFE chimafikira pa mpando nkhope ndi outsides flange chisindikizo awiri, kwathunthu kuphimba EPDM elastomer wosanjikiza mpando, amene amapereka kulimba kwa kusindikiza valavu zimayambira ndi chatsekedwa chimbale.
Kutentha kwapakati: - 10°C mpaka 150°C.
Virgin PTFE (Polytetrafluoroethylene)
PTFE (Teflon) ndi polima yopangidwa ndi fluorocarbon ndipo nthawi zambiri imakhala yosamva mapulasitiki onse, pomwe imasungabe zinthu zabwino kwambiri zamafuta ndi magetsi. PTFE ilinso ndi coefficient yotsika ya kukangana kotero ndi yabwino kwa ambiri otsika torque ntchito.
Izi sizoyipa komanso zovomerezeka ndi a FDA pazakudya. Ngakhale kuti makina a PTFE ndi otsika, poyerekeza ndi mapulasitiki ena opangidwa ndi injini, katundu wake amakhalabe wothandiza pa kutentha kwakukulu.
Kutentha kwapakati: - 38°C mpaka +230°C.
Mtundu: woyera
Mphamvu ya Torque: 0%

Wopangidwa kuchokera ku kuphatikiza kolimba kwa PTFE (polytetrafluoroethylene) ndi EPDM (ethylene propylene diene monomer rabara), mphete yosindikizirayi imatsimikizira kugwira ntchito kosayerekezeka. Chigawo cha PTFE chimatsimikizira malo oterera, opangidwa ndi mankhwala-osagwira ntchito kuti akhale oyera komanso kupewa kuipitsidwa, makamaka pazaukhondo. Mosiyana ndi zimenezi, kuwonjezera kwa EPDM kumapangitsa kuti mphete yosindikizira ikhale yosasunthika motsutsana ndi kusiyana kwa kutentha ndi mankhwala ovuta, kuonetsetsa kuti kusindikizidwa kolimba komanso moyo wautali wautumiki ngakhale pansi pa kutentha kwambiri - Kutentha Kwambiri. kukula kwake, kuchokera ku DN50 kupita ku DN600, ndikupangitsa kuti ikhale chisankho chosunthika pamapulogalamu osiyanasiyana. Kaya ndi madzi, mafuta, gasi, mafuta oyambira, kapena malo amtundu wa asidi, njira yosindikizirayi imakhala yovuta. Ma valve agulugufe ndi lug-mavavu agulugufe amtundu wawiri-half shaft agulugufe opanda mapini, kupangitsa kuyika ndi kukonza molunjika komanso mosavutikira. Kupititsidwa ndi kukwera
