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%

The Bray PTFE EPDM Butterfly Valve Liner yochokera ku Sansheng idapangidwa kuti ikhale yokwanira bwino mavavu agulugufe agulugufe osindikizira, kuphatikiza ma valve agulugufe amtundu wa pneumatic wafer komanso ma valve agulugufe amtundu wawiri theka la shaft opanda pini. Kusinthasintha kumeneku kumapangitsa kuti ma liner athu agwirizane bwino ndi ntchito zosiyanasiyana zamafakitale, kuyambira kumtunda-kutentha m'malo opangira magetsi ndi mafakitale a petrochemical kupita kumadera ovuta kwambiri pazamankhwala, kupanga zombo, ndi zitsulo, kungotchulapo zochepa chabe. Zomangira zathu zimapezeka mumiyeso yoyambira ku DN50 mpaka ku DN600, zomwe zimatengera kukula kwa madoko komanso kuwonetsetsa kuti kutsetsereka, kutayikira - umboni wokwanira pakugwiritsa ntchito kulikonse. Chomwe chimasiyanitsa Bray PTFE EPDM Butterfly Valve Liner ndi magwiridwe ake osayerekezeka pansi pa kutentha kwambiri komanso zinthu zowononga, zomwe zida zachikhalidwe zimatha kulephera. Gawo la PTFE la liner limapereka kukana kwapadera kwamankhwala, kuwonetsetsa kuti valavu imagwirabe ntchito ngakhale ikawonetsedwa ndi media zaukali. Pakalipano, gawo la EPDM limapereka kusungunuka ndi kukhazikika kofunikira kuti mukhale ndi chisindikizo cholimba, kuchepetsa bwino zofunikira zosamalira komanso kukulitsa moyo wa valve. Zopangidwa mwatsatanetsatane komanso zopangidwa mwapamwamba kwambiri, zomangira izi ndi umboni wa kudzipereka kwa Sansheng Fluorine Plastics pakuchita bwino komanso luso laukadaulo wosindikiza.
