Z64H water seal gate valve, DS/Z series adopts double gate double direction elastic seal, open and close, flexible, fast and sealed reliably. The valve cap packing has a water sealing structure, and when the interface passes through the pressure 0.6-1MPa water, the system can be isolated from the atmosphere, and the system has good air tightness. The utility model has the advantages of simple structure, compact and reasonable structure, convenient overhaul and long service life. In the pipeline to sit open and close device, must be in full open or semi open state, shall not be used to regulate flow. The valve connecting flange, welding form two, drive for manual, electric two, DS series water seal valve suitable for nominal pressure is less than 10.0MPa, the temperature is less than or equal to 425 DEG C, the pipeline working medium is water, steam, oil and non corrosive gases on the opening and closing device, especially suitable for steam turbine vacuum cooling system of power plant.
