Heke Valve Flanged End

Na ho na le phapang e kholo lipakeng tsa khokahanyo ea flanged le khokahanyo e kentsoeng ka khoele ho li-valve tsa heke?

Likhokahano tse nang le mahlakore a mabeli li sebelisa li-flange, liboutu le li-gaskets ho hokahanya liphaephe le li-valve. Li lekana bophara ba liphaephe tse kholo le mela ea indasteri e nang le khatello e phahameng. Ho qhaqha bakeng sa ho lokisoa ho bonolo, 'me ts'ebetso ea ho tiisa e lula e tsitsitse nako e telele.

Ho buloa ha karolo e itseng ho boetse ho baka ho thothomela ho matla le hamore ea metsi e senyang valve le liphaephe tse hokahaneng. Li-valve tsa globe kapa li-valve tsa bolo li loketse haholo haeba ho hlokahala phetoho ea phallo.

Ke mefuta efe ea boholo bo tloaelehileng le litekanyetso tsa khatello tseo Gate Valve Flanged End e atisang ho kena ho tsona?

Mefuta e tloaelehileng ea mabitso e koahela DN50 ho DN1200. DN80, DN100, DN150, DN200 le DN300 ke boholo ba rona bo rekoang haholo bakeng sa merero ea indasteri le ea masepala.

Likarolo tse tloaelehileng tsa khatello li kenyelletsa litsamaiso tse peli tse kholo:

Lisebelisoa tsa 'mele oa valve le wedge li khethoa ho latela seaplane le mocheso:

WCB carbon steel: khetho ea rona ea mantlha, matla a tiileng bakeng sa oli e tloaelehileng, metsi le mouoane oa mocheso o mahareng

SS304 / SS316 tšepe e sa jeleng paate: anti-corrosion, e loketseng lipeipi tsa mokelikeli oa lik'hemik'hale le metsi a leoatle.

Ductile iron: khetho ea moruo bakeng sa lits'ebetso tsa metsi a hloekileng a masepala a nang le khatello e tlase

Ho boetse ho na le lisebelisoa tse fapaneng tsa ho tiisa: ho paka graphite bakeng sa mouoane oa mocheso o phahameng, RPTFE bakeng sa mecha ea litaba e senyang e fokolang, le Stellite hard alloy bakeng sa lifahleho tse thibang ka khatello e phahameng.
