Power station gate valve is an important valve used in high temperature and high pressure environment, widely used in petroleum, chemical, thermal power station and other industrial fields. These valves are designed to cut off or connect media such as steam, water and oil in piping systems. Here are some key information about power station gate valves:

Design and manufacturing standards: The design and manufacturing of power station gate valves usually follow GB/T12234, ASMEB16.34 and other standards.
Structural length and interface connection size: usually according to JB/T3595 or GB/T12224 standard.
Nominal pressure: The nominal pressure range of power station gate valves is usually from 200 to 320, and the working pressure classes include P 55 100V, P 55 140V and P 55 170V.
Sealing surface material: The sealing surface of the valve seat and valve disc is usually made of cobalt-based cemented carbide plasma spray welding, which has good wear resistance and abrasion resistance.
Stem treatment: The stem is treated with corrosion resistance nitriding to improve corrosion resistance and abrasion resistance.
Mode of operation: The power station gate valve can be manually operated, geared or electrically operated.
Applicable medium: Power station gate valve is suitable for water, oil, steam and other media.
Features: The power station gate valve has the characteristics of low fluid resistance, good sealing performance, convenient operation and easy maintenance.
Self-cleaning structure: Some power station gate valves are designed with a self-cleaning structure that automatically removes buildup on the sealing surface when the valve is opened.
Opening and closing process: The opening and closing process of the power station gate valve involves the mechanical movement of the valve stem and the rotation of the valve to ensure that the valve can be reliably sealed under various working conditions.
Power station gate valve plays an irreplaceable role in industrial applications because of its high temperature and high pressure characteristics. When selecting and using power station gate valves, their design standards, operating conditions and maintenance requirements should be considered to ensure the safety and efficiency of the system.
