The power station gate valve has small fluid resistance, and the internal medium channel of the valve body is
directly connected. The medium does not change its flow direction when the gate flows through the gate valve. The pressure is self-tightly sealed, and both ends of the valve are welded connections. The torque required for opening and closing is small, the body structure is simple, the manufacturing process is better, the sealing performance is
good, and the corrosion of the dense cover when the full opening is less. The scope of applications is wide.
Because the phenomenon of the long water hammer is not easy to occur. The medium can flow in any direction on both sides and easy to install.
◎ Design Standard: NB/T47044
◎ Main Material: Carbon steel, Stainless Steel, Alloy Steel, Etc.
◎ Size Range: NPS2~NPS24/DN50~DN600
◎ Pressure Level: Class600~ Class 2500/PN100~PN420
◎ Temperature Range: -29℃~650℃
◎ Application Scenario: The power station gate valve is generally used in the shape of the shape of the valve without strict requirements, but the use conditions are more harsh. Such as high-temperature and high-voltage thermal power plants such as power industries and oil refining and other fields.
The Cryogenic and High Performance Butterfly Valve adopts an offset valve stem and eccentric butterfly plate design. When opening and in the middle position, the valve seat and the butterfly plate do not contact each other, which reduces the friction on the valve seat while reducing the torque, and improves the durability of the valve. It is a high-performance regulating and cutting valve. The valve is designed to handle various media that are most difficult to handle in today's industrial environment, including liquid oxygen, liquid natural gas and other cryogenic liquids.
The axial-flow check valve has a unique axial flow design, and its spool is aligned with the flow direction, significantly reducing the resistance loss when the fluid passes through. The spool is driven by spring or fluid pressure for quick opening and closing. When the fluid is flowing forward, the spool is pushed open and the fluid passes smoothly. When the fluid flows in reverse, the spool is quickly closed, effectively preventing backflow, and ensuring the stability and safety of the system operation.
When the disc of the lift check valve slides along the vertical center line of the valve body and the medium flows forward, the disc is lifted by the fluid thrust and the medium passes smoothly; When the medium stops flowing or reverse flowing, the valve disc quickly closes under the action of its own gravity and the reverse thrust of the fluid to prevent the medium from flowing back. This valve is usually equipped with a guide sleeve to ensure that the disc remains smooth during lifting and accurately falls back onto the seat.
