Emnyama/ eluhlaza PTFE/ FPM +EPDM Isihlalo seValve yerabha yeButterfly Valve Seat
I-PTFE + EPDM izihlalo zevalve yerubha ezidityanisiweyo eziveliswe yi-SML zisetyenziswa kakhulu kwi-textile, isikhululo samandla, i-petrochemical, ukufudumeza kunye nefriji, i-pharmaceutical, i-shipbuilding, i-metallurgy, imboni yokukhanya, ukukhuselwa kwendalo kunye nezinye iinkalo.
Ukusebenza kwemveliso: ukumelana nobushushu obuphezulu, i-asidi elungileyo kunye nokumelana ne-alkali kunye nokumelana neoli; enokomelela kwakhona, yomelele kwaye yomelele ngaphandle kokuvuza.
PTFE+EPDM
I-Liner ye-Teflon (PTFE) iyaleka i-EPDM edityaniswe kwiringi ye-phenolic eqinileyo kwiperimeter yesitulo sangaphandle. I-PTFE idlulela ngaphaya kobuso besihlalo kunye nedayamitha ye-flange yetywina yangaphandle, igubungele ngokupheleleyo i-EPDM elastomer umaleko wesihlalo, ebonelela ukomelela kweziqu zevalve yokutywina kunye nediski evaliweyo.
Uluhlu lobushushu: -10°C ukuya ku-150°C.
I-PTFE enyulu (i-Polytetrafluoroethylene)
I-PTFE (i-Teflon) yi-polymer esekwe nge-fluorocarbon kwaye iqhelekile ukuba yeyona khemikhali imelana kuzo zonke iiplastiki, ngelixa igcina iimpawu ezigqwesileyo zokufudumeza nombane. I-PTFE ikwanayo ne-coefficient ephantsi ye-friction ngoko ifanelekile kwizicelo ezininzi ze-torque ephantsi.
Esi sixhobo asingcolisi kwaye samkelwe yi-FDA kwizicelo zokutya. Nangona iimpawu zoomatshini ze-PTFE ziphantsi, xa kuthelekiswa nezinye iiplastiki ezenziwe ngobunjineli, iimpawu zayo zihlala ziluncedo kuluhlu olubanzi lobushushu.
Uluhlu lobushushu: -38°C ukuya +230°C.
Umbala: mhlophe
Torque adder: 0%

Yenziwe ukusuka kwindibaniselwano ephezulu - yodidi lwe-PTFE (i-Polytetrafluoroethylene) kunye ne-EPDM (i-Ethylene Propylene Diene Monomer), lo msesane wokutywina ujongana nemfuno engundoqo yetywina elomeleleyo elinokumelana noluhlu lweemfuno zokusebenza. I-PTFE, eyaziwa ngokuxhathisa okukhethekileyo kweekhemikhali kunye nokukhuhlana okuphantsi, izibini ngokugqibeleleyo kunye nemozulu ye-EPDM ephawulekayo kunye nokumelana ne-ozone, idala itywina elilawula ngokufanelekileyo iimeko ezingqongileyo zokushisa ngelixa ligcina ingqibelelo yalo kumanzi, i-oyile, iigesi, iziseko, kunye ne-acids. Oku kubini-i-synergy yezinto eziphathekayo iqinisekisa ukuba ukusebenza kwevalve kuhlala kuhamba kakuhle kwaye kusebenza kakuhle, ukunciphisa iindleko zokugcina kunye nexesha lokunciphisa kakhulu.Iringi yethu yokutywina ifanelana noluhlu olubanzi lweesayizi zevalvu, ukusuka kwi-DN50 ukuya kwi-DN600, iyenza ibe yinto eguquguqukayo kwizicelo ezahlukeneyo ezibandakanya iimeko eziphezulu - zobushushu. , ezixhaphake kwizikhululo zamandla kunye nezityalo zepetrochemical. Uyilo lujolise kuhlobo lwe-wafer olusembindini oluthambileyo lokutywinwa kwiivalvu zebhabhathane, kubandakanywa iivalvu zebhabhathane zomoya, kunye nohlobo lwelug oluphindwe kabini lweevalvu zebhabhathane ezinesiqingatha ngaphandle kwezikhonkwane. Le nto isetyenziswayo jikelele kwisicelo, idityaniswe nezinto zayo eziphezulu- zokusebenza, yenza i-PTFE EPDM yethu ikhonkco yevalve yebhabhathane yokutywina ibe licandelo eliyimfuneko kumashishini afuna ukuthembeka ngaphandle kokuthomalalisa umgangatho okanye ukusebenza kakuhle. Ngokuzibophezela kweSansheng Fluorine Plastics 'kwizinto ezintsha kunye nokuqina, le ringi yokutywina ayimeli nje imveliso, kodwa isisombululo esibanzi kwimingeni yezoshishino zanamhlanje.
