Valve sealing hi industrial sector hrang hrang tan chuan universal technology pawimawh tak a ni. Petroleum, chemical, ei leh in, damdawi, paper siam, tui hmanga power siam, lawng siam, tui supply leh drainage, smelting, leh energy te ang chi sector-te chauh ni lovin, aviation leh aerospace ang chi industry hmasawn tak takte pawh hi a inzawm tlat a ni.
Valve sealing material hman tlanglawn tak tak te
Rubber hmanrua: 1.1.Rubber hi valve seal siamna atana hman tlanglawn ber pakhat a ni a, a bik takin inphengphehlepvalve a nilehgate valve te a awm bawk. Rubber chi hrang hrang hman tlanglawn tak chu Neoprene Rubber te hi a ni, viton, leh silicon rubber te a ni. Heng thilte hian elasticity leh corrosion resistance tha tak a pe a, hei vang hian media hrang hrang seal nan a tha hle.
Telflon a ni(PTFE): (PTFE) a ni.PTFE hi plastic material tha tak a ni a, valve seal-ah hman lar tak a ni. Chemical leh temperature resistance tha tak a neih avangin temperature sang, pressure sang leh corrosive media awmna hmuna hman atan a tha hle. PTFE seal hi hman tlanglawn tak a nicheck valve te a awm bawklehbutterfly valve te pawh a awm.

Composite material hman hian valve sealing performance a ti tha zual hle.
Valve sealing material hnathawh dan tur a tarlang
Valve sealing material thlan hunah a hnuaia performance indicator te hi ngaihtuah a ngai a ni:
Lum leh vawt tehnaResistance: a ni.Sealing material pakhat temperature range hi a hnathawh dan tehna atana thil pawimawh tak a ni. Material hrang hrang hian temperature resistance degree hrang hrang an nei a. Rubber materials hi a tlangpuiin temperature hniam zawka hman atan a tha a, PTFE leh metal material hi temperature sang zawka hman atan a tha zawk thung.
Corrosion a awmResistance: a ni.Valve hi chemical media hrang hrang phurh nan hman a ni fo thin a, chuvangin sealing material-a corrosion resistance hi a pawimawh hle. PTFE leh specialty rubber thenkhat chu he lamah hian an tha hle a, chemical chi hrang hrang atanga corrosion te chu a do tha hle.
Compression Set a ni: 1.1.Hei hian sealing material-in hun rei tak pressure hnuaia a sealing property a vawng reng theih dan a teh a ni. Compression set a tlem chuan material sealing performance a tha zawk.
