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.
Compared with other valve products, HTHP Slab Gate Valve is characterized by high temperature and high pressure. Among them, grooved flange is designed as a unique self-tight-seal structure. The higher the pressure, the more reliable the sealing performance. Due to the characteristics of performance and technical characteristics and working conditions, the product has also formed the characteristics of other products that cannot be replaced. This type of valve should generally be installed horizontally in the pipeline. The high-temperature and high-pressure gate valve has the design characteristics of ordinary wedge-type gate valves. The valve body has a guide mechanism to prevent rotation when the gate is turned on or closed to ensure that the sealing surface of the valve seat is accurate accordingly. At the same time, the wedge valve does not rub with the valve seat before turning off, thereby reducing the wear of the cover and effectively extending the service life of the valve.
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.
The valve disc of the Cryogenic Lifting Check Valve adopts a vertical lifting structure and is equipped with a cobalt-based alloy sealing surface. It can achieve rapid response and reliable sealing when the medium pressure changes. The product complies with BS 6364 and API 6D standards and is suitable for the transportation systems of low-temperature media such as LNG and liquid oxygen. The working pressure can reach Class 2500 and meets the strict working conditions requirements in the petrochemical and air separation fields.
