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 ndi EPDM, mphete yosindikizirayi imapangidwa makamaka kuti ipereke kukana kosagwirizana ndi zofalitsa zambiri monga madzi, mafuta, gasi, mafuta oyambira, ngakhale ma acid owononga. Makhalidwe apadera a PTFE amapereka kukhazikika kwapadera kwa kutentha ndi kusasunthika kwa mankhwala, pamene EPDM imathandizira kwambiri kupirira komanso kusinthasintha kwa nyengo, kupangitsa mphete yosindikizirayi kukhala yabwino kwa mapulogalamu omwe akukumana ndi kutentha - njira ya valavu yagulugufe ya pneumatic, ikuwonetsa mapangidwe apamwamba omwe amatsimikizira kugwira ntchito bwino. Ndi kukula kwa madoko kuyambira ku DN50 mpaka ku DN600, ma valve athu ndi osinthika mokwanira kuti azitha kugwira ntchito zambiri zowongolera kuyenda. Zophatikizika zatsopano zophatikizika ndi ma flange kumapeto, kuphatikiza kusankha pakati pa valavu yagulugufe ya theka la shaft yopanda pini, onetsetsani kuti ili yotetezeka komanso yotayikira-kuyika kwaulere pakukhazikitsa kulikonse. Kaya ndi mavavu agulugufe kapena mavavu akumpando a ptfe, mphete yathu yosindikizira ya butterfly resilient resilient valve imadziwika ngati mwala wapangodya wodalirika komanso wogwira ntchito bwino m'mafakitale ovuta.
