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%

Yakhiwe kwindibaniselwano eyomeleleyo ye-PTFE (polytetrafluoroethylene) kunye ne-EPDM (i-ethylene propylene diene irabha ye-monomer), le ringi yokutywina iqinisekisa ukusebenza okungenakulinganiswa. Icandelo le-PTFE liqinisekisa umphezulu omtyibilizi, wekhemikhali-oxhathisayo olungele ukugcina ubunyulu nokuthintela ungcoliseko, ngakumbi kwizicelo zococeko. Ngakolunye uhlangothi, ukongezwa kwe-EPDM kukhuthaza ukomelela komsesane wokutywina ngokuchasene nokwahluka kwamaqondo obushushu kunye neekhemikhali ezirhabaxa, ukuqinisekisa ukutywinwa okuqinileyo kunye nobomi benkonzo owandisiweyo naphantsi kweemeko zobushushu.IRingi yethu yokutywina yeButterfly Compounded Butterfly yenzelwe ngobuchule ukuba ilingane noluhlu olubanzi lwevalvu. ubukhulu, ukusuka kwi-DN50 ukuya kwi-DN600, iyenza ibe lukhetho oluguquguqukayo kwizicelo ezahlukeneyo. Nokuba ngamanzi, i-oyile, irhasi, i-oyile esisiseko, okanye iindawo ezineasidi ezinobundlobongela, esi sisombululo sitywina siphakamisa umngeni. Uqhagamshelo lwe-wafer kunye nesiphelo se-flange, kunye nokuhambelana kwazo zombini iivalvu zebhabhathane ze-wafer kunye ne-lug-uhlobo oluphindwe kabini-i-valve ye-butterfly enesiqingatha se-shaft ngaphandle kwezikhonkwane, yenza ufakelo nogcino oluthe ngqo kunye nenkathazo-esimahla. Iphuculwe kukusebenza kwayo okuphezulu phantsi kweemeko ezigqithisileyo, le mveliso iyi-asethi eyimfuneko kumashishini ajolise ekusebenzeni kakuhle kunye nokuthembeka.
