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 kwapamwamba - kalasi ya PTFE ndi EPDM, Mpando wathu wa Stainless Steel Butterfly Valve PTFE unapangidwa kuti uzipereka mphamvu zosindikizira zosayerekezeka komanso zolimba. Makhalidwe apadera a PTFE, kuphatikizapo kulimba kwa EPDM, kupanga mpando wa valve uwu wokhoza kupirira ma TV osiyanasiyana - kuchokera kumadzi ndi mafuta kupita ku gasi, mafuta oyambira, ngakhalenso zidulo zaukali. Kusinthasintha kumeneku kumatsimikizira kuti mipando yathu ya valve ndiyo njira yabwino yothetsera ntchito m'magawo osiyanasiyana, kuphatikizapo, koma osati kokha ku nsalu, kupanga magetsi, mafakitale a petrochemical, kutentha ndi kuziziritsa machitidwe, mankhwala, kupanga zombo, kukonza zitsulo, makampani opepuka, ndi kuteteza chilengedwe. Mpando wa valavu wapangidwa kuti ugwirizane bwino ndi mavavu agulugufe kuyambira DN50 mpaka DN600 mu kukula kwa doko, ndikupangitsa kuti ikhale yabwino kwa onse awiri ndi flange mapeto kugwirizana. Kusinthasintha kumeneku, kuphatikizidwa ndi valavu yapamwamba - kukana kutentha, kumapangitsa kukhala chisankho choyenera kwa malo omwe ntchito zapamwamba ndi zodalirika sizingagwirizane - Kuphatikiza apo, kusankha pakati pa valavu yagulugufe-mtundu wapakati wofewa wosindikizira gulugufe ndi valavu yagulugufe yamtundu wa nusu shaft yopanda pini imapereka kusinthasintha pakuyika ndikuyika. Kuwonetsa bwino kwake, PTFE ndi EPDM chigawo sichimangotsimikizira chisindikizo cholimba komanso chimapangitsa kuti valve ikhale yogwira ntchito, kuchepetsa kufunikira kokonzekera kawirikawiri kapena kusinthidwa. Kaya timagwiritsidwa ntchito poyang'anira madzi, mafuta, gasi, kapena njira ina iliyonse yovuta, Stainless Steel Butterfly Valve PTFE Seat yathu imayimira ukadaulo wapamwamba kwambiri wosindikiza ma valve, kumapereka magwiridwe antchito ndi kudalirika kosagwirizana.
