Seal valve structure characteristics and uses: 1, using the flange bolt connection, both ends of the branch pipe flange connections or welded connections. 2, stuffing and sealing structure is designed to water, access to 0.6 ~ 1.6Mpa water filler, friction is small, sealed Weifang valve make the system isolated from the atmosphere to ensure a good air tightness. 3, the opening and closing parts adopt double plate bi-elastic sealing, open and close easily, reliable seal, good performance. 4, stem quenched and the nitrogen treatment, good corrosion resistance, scratch resistance and abrasion resistance. 5, simple structure, easy compact and reasonable DSZ41H seal gate sales, maintenance and long valve life, attractive appearance. 6, the valve work must be fully open or fully closed position, do not adjust the valve. Valve types, according to the sealing surface configuration can be divided into wedge gate-type valve and parallel gate-type valve, wedge gate-type valve can be divided into: single-gate type, gate-type double plate and elastic; parallel gate-type valve can be divided into single-gate type and double plate. Divided by the threaded stem position can be divided into two clear shot valve gate and dark bar. Valve Co., Ltd. Shandong Everbright production of such types of valves wide range of applications, reliable, no leakage, leakage phenomenon, frequent switching is not stuck, rusted, the majority of chemical plants, thermal power plants, steel mills, printing and dyeing, the best choice for food factory.
