Butterfly valve in soft seal class structure leh performance inhriattirna

Butterfly valve hi khawpui sakna, petrochemical, metallurgy, electric power leh industry dangteah hman a ni nasa hle a, medium pipeline-ah chuan device tha ber flow cut off emaw adjust emaw a ni. Butterfly valve structure ngei pawh hi pipeline chhunga opening leh closing parts tha ber a ni a, tunlai pipeline hawn leh khar parts hmasawnna lam hawi a ni. Center line soft seal butterfly valve kan nei tlangpui a, chu chu temperature pangngai, low pressure working condition-ah te, tui supply leh drainage-ah te, tui humhalhna project-ah te, municipal construction leh field dang dangah te hman a ni ber. A hnuaia tarlan te hian a bik takin single eccentric butterfly valve, double eccentric butterfly valve leh triple eccentric butterfly valve products te a rawn tarlang a ni.

A hmasa berin, a single eccentric structure ofsoft seal butterfly valve a ni, seat sealing cross-section emaw butterfly plate thickness of the direction of the equidistant line leh center of rotation of the valve stem relative eccentric, chutiang chuan butterfly valve chu hawn a nih laiin, butterfly plate sealing surface chu valve seat sealing surface atanga zawi zawiin a hla ta a ni. Butterfly plate rotation to 20 ~ 25 °, butterfly plate sealing surface chu valve seat sealing surface atanga inthen vek a ni a, chutiang chuan butterfly valve chu hawnna process-ah, sealing surface pahnih inkara relative mechanical wear leh extrusion chu nasa takin a tlahniam a, chutiang chuan butterfly valve sealing performance chu a ti tha thei a ni. He design hi a bik takin butterfly plate leh valve seat inkar extrusion atanga elastic deformation lo awm, butterfly valve sealing a nih theih nan a innghat a ni.

Single eccentric butterfly valve atanga chhut chuan butterfly plate rotating center chu valve flow path center line atanga offset a ni a, hei hian butterfly valve chu hawn laiin cam effect a siam a, chutiang chuan butterfly plate sealing surface chu valve seat sealing surface atanga single eccentric structure aiin a inthen rang zawk thei a ni. Butterfly plate chu 8°~12° a a inher chuan butterfly plate sealing surface leh valve seat sealing surface chu a inthen vek a ni. He structure design hian sealing surface pahnih inkara relative mechanical wear leh extrusion deformation nasa takin a tihtlem a, hei hian butterfly valve sealing performance a ti tha hle.

Tin, a bulpui ber chudouble eccentric butterfly valve a awm bawk, seat sealing surface-a center line chuan valve-a center line nen angular eccentricity a siam a, chu chuan butterfly plate hawn lai hian butterfly plate sealing surface chu a hawn lai hian seat sealing surface aṭangin a inthen nghal vek a, a khar lai hian seat sealing surface chu a contact leh press chauh a ni. He eccentricity inzawmkhawm danglam tak hian cam effect chu a hmang tangkai hle a, valve hawn leh khar huna butterfly valve sealing vice sealing surface pahnih inkara mechanical friction leh abrasion awm chu a ti bo vek a, abrasion leh leakage awm theihna pawh a ti bo bawk. Extruded seal chu torque seal-ah thlak a ni a, sealing pressure siamremna chu pawn lam driving torque siamrem hmangin a thleng thei a, chutiang chuan three eccentric structure sealed butterfly valve-a sealing performance leh service life chu nasa takin a tichangtlung a ni.

Chu bakah, Tianjin Tanggu Water Seal Valve Co., Ltd. hi technology lama hmasawn tak rubber seated valve supporting enterprise a ni a, a thil siamte chu resilient seat wafer butterfly valve, lug butterfly valve, double flange concentric butterfly valve, balance valve, wafer dual plate check valve,Air Release Valve a ni, Y-Strainer leh a dangte. Tianjin Tanggu Water Seal Valve Co., Ltd. ah hian industry standard sang ber nena inmil first-class product kan pe thei hi kan chhuang hle. Valve leh fitting hrang hrang kan neih avangin i tui system atana solution tha ber kan pe thei ang tih i ring thei ang. Kan thil siam chungchang leh kan tanpui theih dan tur hriat duh chuan vawiin hian min rawn biak theih reng e.
