      The purpose of the power station valve and technical standards
      SendTime:2017-02-28  Views:

        Dun creek, the main products are: high pressure valve gate valve, globe valve, ball valve, butterfly valve, check valve, regulating valve, high temperature and high pressure valve, API valves, high pressure pipe fittings, flanges, corrugated tube valve series and non-standard valve and so on dozens of varieties, the products are widely used in electricity, gas, gas, oil, medicine, chemical industry, boiler, chemical fertilizer, metallurgy, mining industry, nuclear industry, electronics, urban construction and so on.

        Here, we come to understand the purpose of the power station valve under and technical standards. To understand together.

        "Power station valve also known as the" plant dedicated valve, the pipeline mainly used in the thermal power plant system, cut off or connect pipe medium. Applicable medium: water, steam and other corrosive medium. Power station valve compared with other valve products is characterized by high temperature and high pressure, the unique since the seal design, the higher the pressure, the more reliable seal. Because of performance technology characteristics, operating mode of the special products have formed the characteristics do not replace the other products.


        Power station valve is mainly used in power plants, boilers, etc. Main characteristics and application: this series of valves with advanced port straight through such as structure, greatly reduce the flow resistance coefficient and energy loss, significantly increases the service life of the valve, and performance.

        Valve lumen USES pressure self-tightening seal structure, good sealing performance. For welding structures on both ends of the tube. Disc and seat sealing surface using department too vertical (stellite) cobalt-based hard alloy surfacing and become, wear-resisting, high temperature resistance, good corrosion resistance, abrasion resistance. Stem the conditioning and surface nitriding treatment, has good corrosion resistance and abrasion resistance. Open-close part of the structure can be designed according to user requirements into a single, double plate, the different forms such as parallel double plate.
