Dema/Green PTFE/ FPM +EPDM Rubber Valve Seat for Butterfly Valve Seat
PTFE + EPDM yakasanganiswa rubber valve zvigaro zvakagadzirwa neSML zvinoshandiswa zvakanyanya mumucheka, magetsi, petrochemical, kupisa uye firiji, mishonga, kuvaka ngarava, metallurgy, chiedza indasitiri, kuchengetedza kwezvakatipoteredza uye mamwe minda.
Kuita kwechigadzirwa: kukwirira kwekushisa kwepamusoro, yakanaka acid uye alkali kuramba uye mafuta kuramba; ine yakanaka rebound resilience, yakasimba uye yakasimba isina kudonhedza.
PTFE+EPDM
Iyo Teflon (PTFE) liner inofukidza EPDM iyo inosungirirwa kune yakasimba phenolic mhete pane yekunze chigaro perimeter. Iyo PTFE inotambanudzira pamusoro pechigaro zviso uye kunze flange chisimbiso dhayamita, ichivhara zvachose EPDM elastomer layer yechigaro, iyo inopa kusimba kwekuvhara mavharuvhu madzinde uye yakavharwa disc.
Tembiricha yekushisa: - 10 ° C kusvika ku150 ° C.
Mhandara PTFE (Polytetrafluoroethylene)
PTFE (Teflon) ifluorocarbon yakavakirwa papolymer uye kazhinji ndiyo inonyanya kurwisa kemikari pamapurasitiki ese, ichiramba ichichengetedza kunaka kwemafuta uye magetsi ekudzivirira. PTFE zvakare ine yakaderera coefficient yekukwesha saka yakanakira akawanda akaderera torque application.
Ichi chinyorwa hachisi - chinosvibisa uye chinogamuchirwa neFDA chekushandisa chikafu. Kunyange zvazvo michina yePTFE yakaderera, ichienzaniswa nemamwe mapurasitiki akagadzirwa, maitiro ayo anoramba achishanda pamusoro pehupamhi hwekushisa.
Tembiricha tembiricha: - 38 cei c kusvika + 230 ° C.
Ruvara: chena

Crofarte uchishandisa Kucheka - Kugadziriswa Kwemupendero, Iyo Yakakosha Epdm Butterfly Valve Chigaro chinopa mukana wekusarudzika kunyange pasi pekupisa kwakanyanya uye mamiriro ezvinhu akaomesesa. Iyo yakasarudzika yakasanganiswa yePTFE uye EPDM inovimbisa kuti zvigaro zvekuvharidzira hazvisi zvekupokana neyendiheni yeMedia, kusanganisira mvura, gasi, kupa chisimbiso chakavimbika chinodzikisira zvinyoronyoro uye kuderera. Kuwedzera kweiyo Keystone EPDM Butterfly Valve Chigaro chinowedzeredzwa nekuwirirana kwayo nehuremu hwakasiyana-siyana hwebutterfly volve. Kunyangwe iri wafeta type centerline yakapfava inosimbisa buttery butter Uku kuchinja kwakasanganiswa, kunoita kuti isimbe isinganyanye kuita basa rekushandiswa kwechigaro chekusimbisa.
