Isihlalo se-PTFEivalvu yevivane, eyaziwa nangokuthi yi-fluoroplastic lining corrosion-resistant valves, yindlela ye-PTFE resin (nofana amaphrofayili asetjenzisiweko) ebunjiweko (nofana efakwe ngaphakathi) eengcenyeni ze-valve yensimbi nofana yensimbi yomduli wangaphakathi (indlela efanako isebenza kiyo yoke imihlobo yemikhumbi yokugandeleleka kanye ne-piping accessories lining) nofana indawo yangaphandle ye-valve, isebenzisa iimfanelo eziqinileko zokujamelana nezakhiwo eziqinileko iindaba ezibolako ezenziwe zaba ziinhlobo ezihlukahlukeneko zamavalvu nemikhumbi yokugandeleleka.
Amavalvu we-PTFE ahlanganiswe nendlela yokuvala kizo zoke iindawo lapho umkhathi ungafinyelela khona emzimbeni wevalvu, begodu izinto zokuvala zivamise ukwamukela amapulasitiki we-fluorine afana ne-FEP (F46) kanye ne-PCTFE (F3), angasetjenziswa emapayipini anamazinga ahlukahlukeneko we-sulfuric acid, hydrochloric acid, hydrofluoric acid, regigic acid kanye nayo yoke imihlobo ye-organic acid ama-esidi, i-fluoride eqinileko nezinye izinto ezibolako, njll. Kodwana, amavalvu ane-fluorine angaphasi komkhawulo wezinga lokutjhisa (alungele kwaphela amazinga aphakathi kwe--50°C kanye ne-150°C), begodu izinto zokufakwa zingasetjenziswa kiyo yoke imihlobo yemikhumbi yokugandeleleka kanye nezinto zokusebenza zamapayipi. ℃ ~ 150 ℃ hlangana kwemidiya).
Amavalvu we-butterfly ane-PTFE aklanyelwe ukutjhuguluka kwezinye iindawo ezibolako ezine-esidi eqinileko ne-alkali, i-petroleum, amakhemikhali, ukudla nezinye iindawo ezinengi ezikhethekileko ezitlhogekako, afakwe i-PTFE ngaphakathi kwama-valve we-butterfly ajayelekileko namapuleti we-valve, ukwenzela bona umzimba we-valve uhlukaniswe, ukufikelela umphumela wokulwisana nokugqwala.
Indawo yokusebenza: ingathatha indawo yomzimba wevalvu yensimbi engagqwali ngaphasi kweemeko ezijayelekileko, ngokusebenza kweendleko eziphezulu. Ipuleti yevithamini yevalvu yevithamini ifakwe ngendlela yobubanzi bephayiphi. Emseleni wesilinda womzimba wevalvu yevivane, ipuleti levivane elibunjwe njengediski lijikeleza i-eksisi, begodu i-engele yokujikeleza iphakathi kuka-0° no-90°.
Ukuze zivumelane ngcono neendingo zokulawula okuzenzakalelayo kwesimanjemanje, amavalvu we-PTFE anelayini ye-butterfly angafakwa ngama-actuator kagesi nama-pneumatic, begodu angalawulwa ngokufaka amatshwayo wokulawula (4-20mADC nofana 1-5VDC) kanye nokuphakelwa kwamandla kwesigaba sinye ukwenza imihlobo ehlakaniphileko (yokulawula) nokutjhugulula. Inomsebenzi oqinileko, umthamo omncani, ukukhanya begodu utjhiphile, ukusebenza okuthembekileko, ukusekela okulula, umthamo omkhulu wokujikeleza, khulukhulu ofanele umkhakha ophakathi oqinileko, oqukethe iinhlayiya, ubujamo befayibha bomcimbi.
Ukujamelana nokugqwala kwe-PTFE enelayini ye-butterfly valve kungcono kune-PTFE butterfly valve, begodu intengo iyabiza khulu.
Ngaphandle kwalokho, i-Tianjin Tanggu Water Seal Valve Co., Ltd. yi-elastic seat valve esekela amabhizinisi, imikhiqizo yi-elastic seat wafer butterfly valve, lug butterfly valve,Ivalvu yesango, iveli yevithamini ehlanganisiweko yefletjhi ephindwe kabili, iveli yevithamini yefletjhi ephindwe kabili, iveli yebhalansi,i-wafer dual plate check valve, Y-Strainer njalonjalo. E-Tianjin Tanggu Water Seal Valve Co., Ltd., siyazikhakhazisa ngokunikela ngemikhiqizo esezingeni eliphezulu ehlangabezana namazinga aphezulu webubulo. Ngamavalvu wethu ahlukahlukeneko, ungasithemba bona sizokunikela ngesisombululo esihle khulu sehlelo lakho lamanzi. Sithinta namhlanjesi ukufunda kabanzi ngemikhiqizo yethu nokuthi singakusiza njani.
