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 ngokwesiqhelo 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 zobunjineli, iimpawu zayo zihlala ziluncedo kuluhlu olubanzi lobushushu.
Uluhlu lobushushu: -38°C ukuya +230°C.
Umbala: mhlophe
Torque adder: 0%

Yakhiwe ukusuka kwidibaniso eliphezulu-lodidi lwe-PTFE kunye ne-EPDM, iSitulo sethu se-PTFE se-Stainless Steel Butterfly Valve yenziwe ngobunjineli ukunika ukutywina okusebenzayo kunye nokuqina. Iimpawu ezikhethekileyo ze-PTFE, ezidityaniswe nokuqina kwe-EPDM, yenza esi situlo sevalve sikwazi ukumelana noluhlu olubanzi lweendaba - ukusuka emanzini kunye neoli ukuya kwigesi, i-oyile yesiseko, kunye neeasidi ezinobundlobongela. Oku kuguquguquka kuqinisekisa ukuba izihlalo zethu zevalve zisisombululo esigqibeleleyo sezicelo kuwo wonke amacandelo ahlukeneyo, kubandakanywa kodwa kungaphelelanga kwi-textile, ukuveliswa kwamandla, kumashishini e-petrochemical, ukufudumeza kunye neenkqubo zokupholisa, amayeza, ukwakhiwa kweenqanawa, ukusetyenzwa kwesinyithi, imboni yokukhanya, kunye nokukhuselwa kwendalo. Isihlalo sevalve siyilelwe ukuba silingane ngokungenamthungo kwiivalve zebhabhathane ukusuka kwi-DN50 ukuya kwi-DN600 kubungakanani bezibuko, iyenza ibe lukhetho olufanelekileyo kuzo zombini iivalve kunye imidibaniso ekupheleni flange. Oku kuguquguquka, kudityaniswe ne-valve ephezulu - ukumelana nobushushu, kuyenza ibe lolona khetho lufanelekileyo kwiindawo apho ukusebenza okuphezulu kunye nokuthembeka kungenakuxoxisana. Ngaphezu koko, ukhetho phakathi kwe-wafer-uhlobo oluphakathi lwevalve yebhabhathane ethambileyo yokutywina kunye nodidi lwelug oluphindwe kabini lwe-half shaft butterfly valve ngaphandle kwephini lubonelela ngokuguquguquka kwisicelo kunye nofakelo. Ukugxininisa ukusebenza kakuhle kwayo, i-PTFE kunye ne-EPDM i-compound ayiqinisekisi nje isitywina esiqinileyo kodwa iphinde ikhulise ixesha lokusebenza kwe-valve, ukunciphisa imfuno yokugcinwa rhoqo okanye ukutshintshwa. Nokuba iqeshwe kulawulo lwamanzi, i-oyile, irhasi, okanye nasiphi na isixhobo esicela umngeni, iSitulo sethu seStainless Steel Butterfly Butterfly PTFE simele incopho yetekhnoloji yokutywina yevalvu, inikezela ngomgangatho wokusebenza kunye nokuthembeka.
