一．Product Introduction
High temperature valve, also known as power station valve, is mainly used for various power plant piping system, cut off or connect the pipeline media. Applicable medium: water, steam and other non-corrosive media. Power station valves and other products compared to the valve is characterized by high temperature and pressure, a unique self-sealing design, the higher the pressure, the more reliable sealing. Due to the technical characteristics of performance, special conditions of the product also formed the characteristics of other products can not be replaced.
二.Product Features
1, opening and closing without friction. This function completely solves the problem that the traditional valve affects the sealing surface due to mutual friction between the sealing surfaces.
2, the body structure. On the pipeline installed on the valve can be directly online inspection and maintenance, can effectively reduce the device parking, reduce costs.
3, single seat valve design. Elimination of the valve cavity medium due to abnormal pressure and affect the use of safety issues.
4, low torque design. Special structure design of the valve stem, just with a small handle valve can easily open and close.
5, wedge seal structure. Valves rely on the mechanical force provided by the stem, the wedge valve seat pressed to seal, so that the valve seal from the impact of pressure changes in the pipeline under various conditions, the sealing performance has a reliable guarantee.
6, self-cleaning sealing surface structure. When the gate is away from the valve seat, the fluid in the pipeline passes through 360 degrees uniformly along the sealing surface of the gate, which not only eliminates local erosion of the valve seat by the high-speed fluid, but also rushes away the aggregates on the sealing surface to achieve self-cleaning the goal of
