The hazards of harsh working conditions in thermal power plants to valves

Harsh working conditions generally refer to high temperature, high pressure, easy erosion and corrosion conditions, etc. In power plants, the damage of harsh working conditions to valves is usually caused by the energy burst of the medium with high pressure difference, high flow rate and high erosion at a certain point (usually the valve), resulting in valve damage, such as flash evaporation phenomenon.

The harsh working conditions place higher demands on valves. When valves are damaged and show phenomena such as leakage, seepage, dripping and seepage, the harsh working conditions will accelerate the leakage of valves, causing the medium that should be used to do work and generate electricity in the steam turbine to leak and be wasted, resulting in economic losses for thermal power plants and increasing the coal consumption for power generation in power plants.

Weitai Industry has world-leading high-pressure differential steam trap control valves for harsh working conditions that are resistant to erosion. They are made by integral free forging, with high valve body strength and small valve torque, which can be easily opened and closed. This is conducive to the selection of actuator. When the medium enters the valve interior, it is blocked by a specially treated sleeve with very high hardness, weakening the medium energy and further promoting the reduction of medium pressure. Greatly reduce the erosion of the medium on the internal components of the valve. The internal components of the valve are welded with ultra-thick hard alloy, which is of high hardness and resistant to erosion. Moreover, according to the working conditions of the valve, the form of the pressure reducing sleeve can also be changed. The number, position, size of the pressure reducing holes and even the number of layers of the sleeve will be specially designed according to the working conditions. The high-pressure differential steam trap regulating valve for harsh working conditions and anti-erosion provided by Vite Industry features a replaceable valve seat. During the maintenance of the unit, there is no need to cut the valve off the pipeline; it can be replaced and repaired online, which greatly improves the maintenance efficiency, saves time and avoids losses.
