Setulo se Setšo / Botala PTFE/ FPM +EPDM Rubber Valve Seat for Butterfly Valve Seat
PTFE + EPDM litulo tsa li-valve tsa rabara tse entsoeng ke SML li sebelisoa haholo ka masela, seteishene sa matla, petrochemical, futhumatsang le sehatsetsing, meriana, kaho ea likepe, tšepe, indasteri e khanyang, ts'ireletso ea tikoloho le masimo a mang.
Ts'ebetso ea sehlahisoa: ho hanyetsa mocheso o phahameng, ho hanyetsa acid e ntle le alkali le ho hanyetsa oli; e nang le mamello e ntle, e tiileng le e tšoarellang ntle le ho lutla.
PTFE+ EPDM
Teflon (PTFE) liner e koahela EPDM e kopantsoeng le reng e thata ea phenolic karolong e ka ntle ea setulo. The PTFE fetela ka holim'a lifahleho litulo le outsides flange tiiso bophara, ka ho feletseng kwahela EPDM elastomer lera la setulo, e leng e fana ka ho tiea bakeng sa ho tiisa valve stems le disc e koetsoeng.
Mohato oa mocheso: - 10 ° C ho 150 ° C.
PTFE (Polytetrafluoroethylene)
PTFE (Teflon) ke polymer e thehiloeng ho fluorocarbon 'me ha e le hantle ke eona e hanyetsanang le lik'hemik'hale ho feta lipolasetiki tsohle, ha e ntse e boloka thepa e ntle ea mocheso le motlakase. PTFE e boetse e na le coefficient e tlase ea khohlano kahoo e loketse lits'ebetso tse ngata tse tlase tsa torque.
Thepa ena ha e na - e silafatsa ebile e amoheloa ke FDA bakeng sa lits'ebetso tsa lijo. Le hoja thepa ea mechine ea PTFE e tlaase, ha e bapisoa le lipolasetiki tse ling tse entsoeng ka boenjiniere, thepa ea eona e lula e le molemo ho feta mocheso o pharaletseng.
Mocheso oa mocheso: - 38 ° C ho ea 230 ° C.

O ile a etsa bonnete ba hore ho na le bonolo, valve e na le sethala sa boka se sephara - Tlanya le bokhoni bo bonolo bo tsitsitseng, ba netefatsa hore e koetsoe - Moralo oa eona oa kopana le wafer le ho foka li fella ka ho hlaka, ho kenya ho tsoa habonolo ho feta ho tsamaisa lintho tse fapaneng tsa poping. Litekanyo tsa Valve li lula tsa seboka sa poone tse tsoang ho DN50 ho DN600, li e etsa khetho e feto-fetohang bakeng sa li-tupi tse fapaneng. Ho feta moo, serurubele sa leqheka se sa khoneheng se fana ka taolo e ntlafalitsoeng, e lumellang taolo e sebetsang le bokhabane. Seletso ea rona ea serurubele e lutse le moralo oa eona oa lesela o habeli, o felisa tlhokahalo ea pine, ka hona a fokotsa lintlha tsa ho se atlehe.
