High Pressure Power Station Gate Valve
Introduction:
The main technical parameters of pressure power station gate valve of pound class power station are: PN1.6 ~ 32Mpa; DIN10~600mm; The operating temperature is – 20 º C~+150 º C~425 º C~550 º C. The main materials are carbon steel, chromium molybdenum steel, chromium molybdenum vanadium steel, austenitic stainless steel, etc. Applicable media are water, steam, oil, etc. Power station valve products are widely used in various working conditions of thermal power plants.
Structural features of pressure power station gate valve of pound class power station:
The design, manufacturing, inspection, marking and supply shall comply with relevant domestic standards such as GB, JB and DL.
The material complies with relevant domestic and international standards such as ASME, JIS, GB, JB and DL.
The sealing pairs of all valves are made of Stellite hard alloy with different hardness. The sealing pairs are reasonably matched and have good sealing performance: high temperature resistance, high hardness, abrasion resistance, erosion resistance and long service life.
The upper sealing surface is made of austenitic stainless steel or Stellite hard alloy. It is reliable and corrosion-resistant. The replacement of packing can be carried out without stopping the machine, without affecting the system operation.
The body cover adopts pressure self tightening sealing structure. The higher the pressure, the better the sealing performance.
The gate valve adopts double gate or elastic gate structure, with reliable sealing, flexible action and convenient maintenance.
The connecting part between the valve rod nut and the bracket is equipped with thrust ball bearing, which has small rotating torque, flexible opening and closing, and saves labor and power.
