[Use of the product] 

 Power station gate valves produced by the company: manual, butt welding connection form, open rod wedge rigid single gate plate, the sealing surface material of the valve seat is cemented carbide, the nominal pressure is 1500LB~2500LB, and the valve body material is carbon steel high-temperature and high-pressure power station gate valve. 

 [Structural features] 

 High-temperature gate valves, also known as special valves for power plants, are mainly used to cut off or connect the pipeline medium on the pipeline of various systems of thermal power plants. Applicable media: water, steam and other non-corrosive media. Compared with other valve products, power plant valves are characterized by high temperature and high pressure, unique self-sealing design, and the higher the pressure, the more reliable the sealing. Due to the performance and technical characteristics, the special working conditions make the product form a characteristic that cannot be replaced by other products. 

 1. No friction between opening and closing. This function completely solves the problem that traditional valves affect the sealing surface due to mutual friction between sealing surfaces. 

 2. Top-mounted structure. The valves installed on the pipeline can be directly checked and repaired online, which can effectively reduce device parking and reduce costs. 

 3. Single-seat valve design. The problem that the cavity medium in the valve affects the safety of use due to abnormal pressure increase has been eliminated. 

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

 5. Wedge-shaped sealing structure. The valve is sealed by the mechanical force provided by the valve stem, pressing the gate wedge on the valve seat, so that the sealing of the valve is not affected by the change of pipeline pressure difference, and the sealing performance is reliably guaranteed under various working conditions. 

 6. The self-cleaning structure of the sealed surface. When the gate is dumped from the valve seat, the fluid in the pipeline passes uniformly along the sealed surface of the gate plate in 360 degrees, which not only eliminates the partial flushing of the valve seat by the high-speed fluid, but also flushes away the aggregates on the sealing surface to achieve the purpose of self-cleaning.

Each process, each facility, and each environmental constraint has its own special requirements. Therefore, Dongyan offers a comprehensive range of products covering different performance levels, pressures, different functions and different materials.
