Structural characteristics and uses: 1, the product of the bonnet filler valve chamber having a water seal structure, when the interface through the O.6 ~ 1 MPa pressure water, allows the system isolated from the atmosphere to ensure that the system has good gas seal. 2, DS / Z-series using double plate bi-elastic sealing, opening and closing flexible, fast, reliable sealing. 3, the product structure is simple, compact, easy maintenance, long service life. 4, in the pipeline for opening and closing device, must be in fully open or fully closed state, it may not be used to regulate the flow. 5, valve flange connections and welding, two ways of manual and electric drive. 6, DS series seal valves for nominal pressure ≤1O.OMPa, working temperature ≤425 ℃, the working medium is water, steam, oil pipeline and non-corrosive gases for opening and closing device, especially for thermal power plants Turbine vacuum condensation system. Valve types, according to the sealing surface configuration can be divided into wedge gate-type valve and parallel gate-type valve DSZ41H seal valve manufacturer, wedge gate-type valve can be divided into: single-gate type, double plate and the flexible gate formula ; parallel gate-type valve can be divided into single - ram 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. Product use for nominal pressure seal gate valve seal 100MPa DSZ41H vendors, operating temperature 425 ℃, the working medium is water, steam, oil and non-corrosive gas pipeline for opening and closing device, especially for fire Power vacuum condensing steam turbine system.
