Pound power station gate valve, power station gate valve, gate valve

Product Overview of Pound-Class Power Plant Gate Valve:  

The flow passage of the pound-class power plant gate valve features an equal-diameter straight-through design, allowing the medium in the pipeline to flow smoothly from the inlet end, significantly reducing flow resistance coefficient and energy loss. The valve disc adopts a wedge-type elastic disc, enabling reliable opening and closing under high temperature and high pressure conditions. The connection between the valve body and bonnet employs a self-tightening pressure seal structure, combining a wedge-shaped sealing ring with a four-split ring, ensuring more reliable sealing as pressure increases. A thrust ball bearing and oil cup are installed on the bonnet, allowing periodic application of solid lubricant to reduce operating torque and ensure smooth operation. The packing gland and sleeve adopt a split design to maintain stem concentricity. The inlet and outlet connections can be selected according to operational requirements, including flanged, butt-welded, or other types. 

Advantages of Pound-Class Power Plant Gate Valves:  

Pound-class power plant gate valves can be equipped with a bypass valve installed within the inlet and outlet chamber. When the main valve is closed, opening the bypass valve balances the pressure at both ends, reducing the force required to open the valve and minimizing wear on the gate disc and seat sealing surfaces. The valve features a well-designed packing gland that combines braided graphite, flexible graphite packing, and an intermediate packing sleeve, ensuring no external leakage and meeting environmental protection requirements. This design provides reliable sealing under high-temperature and high-pressure conditions in pipelines, achieving zero leakage and capable of withstanding significant axial and radial forces. This product is particularly suitable for connecting or isolating non-corrosive liquid and gaseous media in high-temperature, high-pressure steam and water systems of thermal power plants.

Application: 

The pound-class power plant gate valve can be equipped with a bypass valve installed in the inlet and outlet chamber of the valve body. When the main valve is closed, opening the bypass valve balances the pressure at the inlet and outlet, thereby reducing the force required to open the valve and minimizing wear on the gate and seat sealing surfaces. Its well-designed packing gland features a combination of braided graphite, flexible graphite packing, and an intermediate packing sleeve, ensuring no external leakage and meeting environmental protection requirements. This design provides reliable sealing for media in pipelines under high temperature and high pressure conditions, achieving zero leakage and capable of withstanding significant axial and radial forces. This product is particularly suitable for connecting or isolating non-corrosive liquid and gaseous media in high-temperature, high-pressure steam and water systems of thermal power plants.
