Isihlalo se-PTFEivalvu yebhabhathane, eyaziwa ngokuba ziivalvu ezinganyangekiyo kwi-fluoroplastic lining, yindlela ye-PTFE resin (okanye iiprofayili ezicutshungulwayo) ebunjiweyo (okanye efakwe ngaphakathi) kwiindawo zoxinzelelo lwentsimbi okanye ivalvu yentsimbi eludongeni lwangaphakathi (indlela efanayo isebenza kuzo zonke iintlobo zeenqanawa zoxinzelelo kunye nezixhobo zepayipi) okanye umphezulu wangaphandle weendawo zangaphakathi zevalvu, isebenzisa iipropati zayo ezikhethekileyo ekuchaseni imidiya enamandla ebolayo eyenziwe kwiintlobo ezahlukeneyo zeevalvu kunye neenqanawa zoxinzelelo.
Iivalvu zePTFE zifakwe i-lining process kuzo zonke iindawo apho i-medium inokufikelela khona emzimbeni wevalvu, kwaye izinto ze-lining zihlala zisebenzisa iiplastiki ze-fluorine ezifana ne-FEP (F46) kunye ne-PCTFE (F3), ezinokusetyenziswa kwimibhobho ene-acid ye-sulfuric eyahlukeneyo, i-hydrochloric acid, i-hydrofluoric acid, i-aqua regia kunye nazo zonke iintlobo ze-asidi ze-organic, ii-asidi ezinamandla, i-fluoride enamandla kunye nezinye izinto ezibolayo, njl. Nangona kunjalo, iivalvu ezine-fluorine ziphantsi komda wobushushu (zifanele kuphela ii-medium eziphakathi kwe--50℃ kunye ne-150℃), kwaye izinto ze-lining zingasetyenziswa kuzo zonke iintlobo zemithambo yoxinzelelo kunye nezixhobo zepayipi. ℃ ~ 150 ℃ phakathi kwemidiya).
Iivalvu zebhabhathane ezifakwe i-PTFE zenzelwe ukuziqhelanisa neendawo ezithile ezirhabaxa ezine-asidi enamandla kunye ne-alkali, i-petroleum, iikhemikhali, ukutya kunye nezinye iindawo ezininzi ezikhethekileyo ezifunekayo, ezifakwe i-PTFE ngaphakathi kweevalvu zebhabhathane eziqhelekileyo kunye neepleyiti zevalvu, ukuze i-medium kunye nomzimba wevalvu zahlulwe, ukuze kufezekiswe isiphumo sokulwa nokugqwala.
Indawo yokusebenza: ingathatha indawo yomzimba wevalvu yentsimbi engagqwaliyo phantsi kweemeko eziqhelekileyo, kunye nokusebenza okubiza kakhulu. Ipleyiti yebhabhathane yevalvu yebhabhathane ifakwe kwicala lobubanzi bombhobho. Kwitshaneli ye-cylindrical yomzimba wevalvu yebhabhathane, ipleyiti yebhabhathane enemilo yediski ijikeleza i-axis, kwaye i-engile yokujikeleza iphakathi kwe-0° kunye ne-90°.
Ukuze zilungelelaniswe ngcono neemfuno zolawulo oluzenzekelayo lwanamhlanje, iivalvu zebhabhathane ezine-PTFE zinokuxhotyiswa ngee-actuators zombane kunye nezomoya, kwaye zinokulawulwa ngokufaka imiqondiso yokulawula (4-20mADC okanye 1-5VDC) kunye nombane wesigaba esinye ukuze kufezekiswe iintlobo ezikrelekrele (ezilawulayo) kunye nezitshintshayo. Inomsebenzi oqinileyo, umthamo omncinci, ukukhanya kunye nexabiso eliphantsi, ukusebenza okuthembekileyo, ukuxhasa okulula, amandla amakhulu okujikeleza, afanelekileyo ngakumbi kwi-medium i-viscous, equlethe amasuntswana, uhlobo lwefayibha yesiganeko.
Ukumelana nokugqwala kwevalvu yebhabhathane efakwe kwi-PTFE kubhetele kunokumelana nevalvu yebhabhathane ye-PTFE, kwaye ixabiso libiza kakhulu.
Ngaphandle koko, iTianjin Tanggu Water Seal Valve Co., Ltd. yivalvu yesihlalo elastiki ephucukileyo exhasa amashishini, iimveliso zezi: ivalvu yebhabhathane yesihlalo esithambileyo, ivalvu yebhabhathane yelug,Ivalvu yeSango, ivalvu yebhabhathane ejikelezileyo eneflange ephindwe kabini, ivalvu yebhabhathane ejiyileyo eneflange ephindwe kabini, ivalvu yokulinganisela,ivalvu yokujonga ipleyiti ezimbini ye-wafer, i-Y-Strainer njalo njalo. KwiTianjin Tanggu Water Seal Valve Co., Ltd., siyazingca ngokubonelela ngeemveliso ezikumgangatho ophezulu ezihlangabezana nemigangatho ephezulu yoshishino. Ngoluhlu lwethu olubanzi lweevalvu kunye nezixhobo, ungasithemba ukuba siza kubonelela ngesisombululo esifanelekileyo kwinkqubo yakho yamanzi. Qhagamshelana nathi namhlanje ukuze ufunde ngakumbi malunga neemveliso zethu kunye nendlela esinokukunceda ngayo.
