Power station gate valve, also known as special valve for power station, is mainly applicable to the pipeline of various systems in thermal power station, cutting off or connecting the pipeline medium. Applicable media: water, steam and other non corrosive media. Compared with other valve products, power station valves are characterized by high temperature and high pressure, and unique self sealing design. The higher the pressure, the more reliable the sealing. Due to the technical characteristics of the performance and the special working conditions, the product also has the characteristics that other products cannot replace.

1. There is no friction when opening and closing. This function completely solves the problem that the traditional valve seals are affected by the friction between sealing surfaces.

2. Top mounted structure. The valves installed on the pipeline can be directly inspected and maintained online, which can effectively reduce the shutdown of the device and reduce the cost.

3. Single seat valve design. The utility model eliminates the problem that the medium in the valve cavity affects the use safety due to abnormal pressure rise.

4. Low torque design. The valve stem with special structure design can be opened and closed easily with a small handle valve.

5. Wedge seal structure. The valve is sealed by pressing the ball wedge onto the valve seat with the mechanical force provided by the valve stem, so that the sealing performance of the valve is not affected by the change of pipeline differential pressure, and the sealing performance is reliably guaranteed under various working conditions.

6. Self cleaning structure of sealing surface. When the ball is tilted away from the valve seat, the fluid in the pipeline passes through the valve seat 360 degrees evenly along the sealing surface of the ball, which not only eliminates the local scouring of the valve seat by the fluid, but also washes away the deposits on the sealing surface, so as to achieve the purpose of self-cleaning.
