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: - I-10 ° C ukuya kwi-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 kwi-230 ° C.
Umbala: mhlophe
Torque adder: 0%

I-teflon byforf vatter valve yokutywina yi-Amialgam ye-PTFE kunye ne-EPDM, izixhobo ezaziwa ngobugwenxa babo kwaye ziyamomelela ngokuchasene nemithombo yeendaba. Icandelo lePPFE leTywina libonelela ngokungaxhasiyo kwiikhemikhali kunye nobushushu obuphezulu, ukuqinisekisa ukuthembeka kwetyhefu ekufumaneni iindawo. Ngaxeshanye, into ebonakalayo ye-EPDM ibonelela nge-elasticity egqwesileyo kunye nokuqina, ukuphucula amandla etywina lokuthobela umzimba wevali kunye nokuqinisekisa ukuvalwa ngokuqinileyo - ukucima. Olu luhlu lwezinto ezivumela ukutywina kwethu lokutywina ukuba luphatha amanzi, ioyile, igesi, ioyile ye-oyile, kunye ne-acidiedia, esenza isisombululo se-acid, sisenza isisombululo esibanzi soluhlu olubanzi lwezicelo. Ngobungakanani bezibuko ezivela kwi-DN50 ukuya kwi-DN600, indawo yethu yohlobo lwesandla esithambileyo sokutywina i-butterfly vatve veterfly vatves kwi-valions ye-valiment yobungakanani, ukuqinisekisa ukuhambelana neenkqubo zakho ezikhoyo. Le mveliso injineli ukuba iququzelele ukufakwa okulula kunye nokugcinwa kwayo, ibonisa ukuphela kwe-wafer okanye i-flanges yokuphela kwendawo yokudityaniswa engenamthungo kulungiselelo lweendlela ezahlukeneyo zokucwangcisa. Uyilo lwe-valve lugxile kwi-lug - Chwetheza i-shaft ephindwe kabini ngaphandle kwePIN, ikhuthaze indlela yokuhamba-hlula-hlula indlela yokuhamba-hlula uxinzelelo lwehla kunye nokusetyenziswa kwamandla. Nokuba umsebenzi wakho ubandakanya ukuphakama okuphezulu - Ukuphatha izinto ezihluphayo, i-teflon ye-teflon butterfly ivalves ithelekise iringi njengesisombululo sakho sokuthembeka kunye nokusebenza kakuhle.
