Products Details

Power station flange gate valve is a kind of valve widely used in power system, mainly used to control the flow of medium in the pipeline. The following is some introduction about flange gate valve of power station in Chinese:

Product overview: Power station flange gate valve is usually used in conjunction with electric actuator to realize remote control valve position switching, easy and quick operation. This valve is suitable for a variety of nominal pressure and working temperature range, generally used in petroleum, chemical, hydraulic and thermal power stations and other systems to cut off or connect the pipeline medium.

Technical features:

The fluid resistance is small, and the sealing surface is less affected by media erosion and erosion.
When opened, the strength is larger, the sealing performance is good, the medium flow is not restricted, no turbulence, no pressure reduction.
The valve has the advantages of simple structure, good manufacturing process and wide application range.
Applicable medium: Power station flange gate valve is suitable for water, oil, steam and acid, alkali, ammonia, urea, sulfur-containing natural gas and other media.

Material and temperature: the main material of the valve can be carbon steel, stainless steel, etc., and the sealing surface may be surfacing with Stellite cobalt-based cemented carbide to improve hardness, wear resistance, high temperature resistance and corrosion resistance. The operating temperature range varies according to the material, generally between -29 ° C and 550 ° C.

Implementation standards: The design, manufacture, structural length, flange size, pressure-temperature grade, test and inspection of power station flange gate valves all follow certain national standards, such as GB/T 12234, GB/T 12221, GB9113, JB79, GB9131 and GB/T 13927.

Models and specifications: There are many types and specifications of valves, such as Z941W, Z941H, Z941Y, etc., suitable for different nominal pressures and working conditions. Their dimensions and main component materials are selected according to the specific operating conditions and media characteristics.

Installation and operation: Electric flanged gate valves can be installed in horizontal or vertical pipe, and the direction of media flow is not limited. For large diameter and high pressure gate valves, it may be necessary to install a bypass valve to reduce the opening and closing torque.

Electric actuator: Electric actuator should have torque control, field operation, manual electric switching and other functions to ensure the stable and safe operation of the valve.

Through the above information, we can understand that the power plant flange gate valve is a compact, easy to operate, good sealing performance of the valve, suitable for a variety of industrial systems and media.
