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 nokuchasana kwe-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 ikholisa ukuba yeyona khemikhali imelana kuzo zonke iiplastiki, ngelixa igcina iimpawu ezigqwesileyo zobushushu kunye nombane wokugquma. I-PTFE ikwanayo ne-coefficient ephantsi ye-friction ngoko ifanelekile kwizicelo ezininzi zetorque 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%

Izangqa zethu zokutywina ze-butterfly valve rings zenziwe zisuka kumxube ophezulu we-PTFE (Polytetrafluoroethylene) kunye ne-EPDM (i-Ethylene Propylene Diene Monomer), iqinisekisa ukuqina okungenakulinganiswa kunye nokuchasana noluhlu olubanzi lwemithombo yomngeni, kuquka amanzi, ioli, igesi, i-oyile. kunye neeasidi. Le khompawundi yodwa inyusa uxhathiso olukhethekileyo lweekhemikhali ze-PTFE, ezidityaniswe nokomelela kunye nokuqina kwe-EPDM, ukwenza isisombululo sokutywina esiqinisekisa ukutywinwa, ukuvuza - ubungqina bobungqina kuluhlu olubanzi lwamaqondo obushushu kunye noxinzelelo.Yenzelwe ukuba ilingane ngokungenamthungo kunye nohlobo lwe-wafer Izivalo zebhabhathane ezithambileyo zokutywina, kubandakanya iivalve zebhabhathane, izitywina zethu ziyahambelana noluhlu olubanzi lweesayizi zevalvu - ukusuka DN50 ukuba DN600. Ngaphezu koko, la makhonkco okutywina ajongana nobuninzi bezicelo, ukusuka phezulu-kwimeko zobushushu kwizikhululo zamandla kunye nezityalo zepetrochemical ukuya kwiindawo ezifunwayo ezifumaneka kumayeza, ukwakhiwa kweenqanawa, isinyithi, kunye nokhuseleko lokusingqongileyo, phakathi kwabanye. Ukuguquguquka kwamakhonkco okutywina amakhonkco evalve yebhabhathane, kudityaniswe nolwakhiwo oluqinileyo kunye nokuthembeka, kubenza babe yinxalenye eyimfuneko kuyo nayiphi na imeko efuna ukutywinwa kokusebenza okungayekeleliyo.
