The power station globe valve is suitable for the pipeline of various systems in the thermal power station to cut off or connect the pipeline medium. Applicable media: water, steam and other non-corrosive media. Compared with other valve products, power station valve is characterized by high temperature and high pressure, unique self-sealing design, the higher the pressure, the more reliable the sealing. Due to the special performance and technical characteristics and working conditions, the product has also formed the characteristics that can not be replaced by other products. a. Frictionless opening and closing: This function completely solves the problem of sealing caused by the friction between the sealing surface of the traditional valve. b. Top type structure: the valve installed on the pipeline can be directly checked and maintained online, which can effectively reduce the device parking and reduce costs. c. Single seat design: eliminate the problem that the medium in the valve cavity affects the safety of use due to abnormal pressure increase. d. Low torque design: The valve stem with special structure design can be easily opened and closed with a small handle valve. e. Wedge seal structure: the valve depends on the mechanical force provided by the valve stem, the valve wedge is pressed to the seat and sealed, so that the sealing of the valve is not affected by the change of pipeline pressure, and the sealing performance is reliably guaranteed under various working conditions. f. Self-cleaning structure of sealing surface: When the ball tilts away from the valve seat, the fluid in the pipeline passes through the valve disc sealing surface into 360 degrees evenly, which not only eliminates the local erosion of the high-speed fluid on the valve seat, but also washes away the accumulation on the sealing surface to achieve the purpose of self-cleaning.
