Butterfly valve keng soft seal class structure ampo performance introduction

Ing butterfly valve maralas yang gagamitan keng urban construction, petrochemical, metallurgy, electric power ampo aliwa pang industriya keng medium pipeline para gawan ing cut off o adjust ing flow ning pekamasanting a device. Ing butterfly valve structure mismu ing pekamasanting a pamuklat ampo pamagsara a bage keng pipeline, ya ing direksyun ning panyulung da reng pipeline ngeni. Keraklan atin kaming center line soft seal butterfly valve, na keraklan gagamitan da keng normal a temperatura, mababang pressure a kundisyun ning obra, antimo ing suplay ning danum ampo drainage, proyektung pamag-ingat keng danum, konstruksyun ning munisipyu ampo aliwa pang larangan. Ing tutuki magpakilala ya keng single eccentric butterfly valve, double eccentric butterfly valve ampo triple eccentric butterfly valve products.

mumuna, ing metung a eccentric a istruktura ningmalambut a seal butterfly valve, seat sealing cross-section o butterfly plate kapal ning direksyun ning equidistant line ampo ing sentru ning pamag-ikot ning valve stem relatibung eccentric, inya ing butterfly valve keng prosesu ning pamagbukas, ing butterfly plate sealing surface bagya-bagya yang marayu keng valve seat sealing surface. Ing butterfly plate rotation keng 20 ~ 25 °, ing butterfly plate sealing surface lubus yang makabukud keng valve seat sealing surface, para ing butterfly valve keng prosesu ning pamagbukas, ing relatibung mechanical wear ampo extrusion pilatan da reng adwang sealing surfaces maragul yang mabawas, para ing butterfly valve performance malyari yang mas masanting. Ing disenyu ayni magdependi ya keng elastic deformation a gagawan ning extrusion pilatan ning butterfly plate ampo ing valve seat para makasiguradung makaseal ya ing butterfly valve.

Base keng single eccentric butterfly valve, ing rotating center ning butterfly plate maka offset ya keng center line ning valve flow path, na gagawang butterfly valve form cam effect kabang magbukas ya, para ing sealing surface ning butterfly plate malyari yang mikakawani keng sealing surface ning valve seat mas mabilis kesa keng single eccentric structure. Potang ing butterfly plate mag-rotate ya keng 8°~12°, ing sealing surface ning butterfly plate lubus yang makabukud keng sealing surface ning valve seat. Ing disenyu na niting istruktura babawasan na ing relatibong mechanical wear ampo ing extrusion deformation pilatan da reng adwang sealing surfaces, na magpasanting keng sealing performance ning butterfly valve.

at keng basehan ningdouble eccentric butterfly valve, ing libutad ning seat sealing surface gagawang angular eccentricity keng libutad ning valve, na gagawang sealing surface ning butterfly plate agad yang makabuklat keng seat sealing surface keng oras ning pamagbuklat kabang magbukas ya ing butterfly plate, at makipag-ugnayan yamu at pindutan ing seat sealing surface keng oras ning pamagsara. Iting makatagulaling a kumbinasyun ning eccentricity gagamit yang ganap a cam effect, ganap nang lalako ing mechanical friction ampo abrasion pilatan da reng adwang sealing surfaces ning butterfly valve sealing vice nung ing valve makabuklat ya at makasara ya, ampo makalako ya ing posibilidad ning abrasion ampo leakage. Ing extruded seal mibayu ya keng torque seal, at ing pamag-adjust ning sealing pressure me-adjust ya keng external driving torque, para ing sealing performance ampo ing service life da reng atlung eccentric structure sealed butterfly valve mas masanting la.

Bukud pa, ing Tianjin Tanggu Water Seal Valve Co., Ltd. metung yang technologically advanced a rubber seated valve a susuporta kareng negosyu, deng produktu ilapin deng resilient seat wafer butterfly valve, lug butterfly valve, double flange concentric butterfly valve, balance valve, wafer dual plate check valve,Balbula ning Pamaglual Angin, Y-Strainer at aliwa pa. King Tianjin Tanggu Water Seal Valve Co., Ltd., pagmaragul mi ing pamamie ming mumunang klasing produktu na makatupad kareng pekamatas a pamantayan ning industria. Kareng kekaming dakal a uri da reng balbula ampo fittings, malyari kang magtiwala kekami na mamye kang perpektung solusyun para keng kekang sistema ning danum. Makipag ugnayan kekami ngeni para abalu mu ing tungkul kareng kekaming produktu ampo nung makananu dakang asaupan.
