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%

Keystone yathu ya PTFE Butterfly Valve Liner imaphatikizapo kusakanikirana kwamakono kwa PTFE ndi EPDM, kupereka chisindikizo chomwe chimatha kumenyana ndi mauthenga osiyanasiyana kuphatikizapo madzi, mafuta, gasi, mafuta oyambira, ngakhale ma acid. Kusinthasintha uku kumapangitsa kukhala chisankho chabwino pamagwiritsidwe ntchito m'mafakitale osiyanasiyana - kuchokera ku nsalu ndi mafuta a petrochemicals mpaka kutentha, firiji, ndi mankhwala. Chisamaliro cha kusankha zinthu chimatsimikizira kuti ntchito zanu zimakhalabe zosasokonezeka, zogwira mtima, komanso zotetezeka.Kuphatikiza apo, kugwirizanitsa kwa mankhwala ndi ma valve kukula kwa DN50 mpaka DN600 ndikugwiritsa ntchito kwake kumtunda-kutentha kumatsimikizira kusinthasintha kwake. Kaya makina anu amagwira ntchito ndi wafer, flange amatha, kapena amafunikira valavu yagulugufe yamtundu wachiwiri theka la shaft yopanda pini, mwala wofunikira wa PTFE butterfly valve liner amalumikizana mosadukiza. Kapangidwe kake kabwino kumawonekeranso ndi kukwanira kwake kwa mavavu agulugufe agulugufe amtundu wofewa komanso ma valve agulugufe a pneumatic wafer, kulonjeza kutayikira-kutsimikizira yankho mu mawonekedwe ophatikizika.
