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 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 ezenziwe ngobunjineli, iimpawu zayo zihlala ziluncedo kuluhlu olubanzi lobushushu.
Uluhlu lobushushu: -38°C ukuya +230°C.
Umbala: mhlophe

I-EPDM + PTFE yethu amakhonkco okutywinwa okudityanisiweyo yi-epitome entsha kwisayensi yezinto eziphathekayo, ukudibanisa ukuqina kunye nokuguquguquka kwerabha ye-EPDM kunye ne-inertness yekhemikhali kunye nokumelana nokushisa kwe-PTFE. Olu qulunqo lwe-hybrid luqinisekisa ukusebenza kakuhle kwizicelo ezibandakanya amanzi, i-oyile, igesi, i-oyile yesiseko, kunye neeasidi ezinobundlobongela. Nokuba ukumashishini epetrochemical, amayeza, aselwandle, okanye akhusela indalo esingqongileyo, izisombululo zethu zokutywina ziyilelwe ukuhlangabezana kwaye zigqithise iimfuno ezingqongqo zobushushu obuphezulu kunye neemeko ezinobungozi. Ngapha koko, uluhlu lwemveliso yethu lubonelela kuluhlu olubanzi lweevalvu I-DN50 ukuya kwi-DN600, ibenza ukuba bafaneleke ngokugqibeleleyo kwiindidi ezahlukeneyo zeevalvu kubandakanya uhlobo lwe-wafer olusembindini oluthambileyo lokutywina iivalve zebhabhathane kunye iivalve zebhabhathane wafer umoya. Iimpawu zoyilo ezizodwa ezifana ne-wafer, i-flange ends, kunye ne-lug uhlobo lwe-lug oluphindwe kabini lwe-shaft ngaphandle kwe-pin lubonelela ngokulula kokufakela kunye nokuqinisekisa ukugcinwa okukhuselekileyo, ukunciphisa umngcipheko wokuvuza. Ukuzibophelela kwethu kumgangatho kunye nokuveliswa kwezinto ezintsha kubonakala kuyo yonke i-EPDM+PTFE edityanisiweyo yeringi yevalve yokutywina esiyivelisayo, sisenza iSansheng Fluorine Plastics ukuba uye kwimithombo yezisombululo ezithembekileyo zokutywinwa kwevalvu.
