1. About jacketed gate valve

In the world of valves, jacketed gate valves are a unique and important presence. Its design concept and performance characteristics make it widely used in many industries. Many people may not know much about this kind of valve. I will analyze the jacket gate valve in depth to help everyone better understand and master the knowledge of this valve, and provide a useful reference for engineering practice.

2. Definition of jacketed gate valve

Jacketed gate valve, also called jacketed gate valve, is a gate valve with a jacket structure. The jacket is usually located on the outside of the valve and can be used to inject cooling or heating media to control the temperature of the media inside the valve. This design makes the jacket gate valve widely used in high temperature, high pressure or situations where precise control of medium temperature is required, bronze valve supplier.

3. Structural characteristics of jacketed gate valve

Valve body: usually made of cast iron, ductile iron, carbon steel, stainless steel and other materials, with good corrosion resistance and mechanical properties. There is a fluid channel inside the valve body, which is connected with the pipeline. The jacket is located outside the valve body and usually consists of a jacket flange, a jacket pipe and other components. It is used to inject cooling or heating medium.

Valve plate: Also called gate, it is a key component for controlling the flow of fluid. Usually made of metal materials, it has good sealing performance and corrosion resistance. The valve plate is connected to the valve stem, and the opening and closing action of the valve plate is realized by rotating the valve stem. In some designs, the valve plate may also have special materials or coatings to improve its corrosion resistance and service life.

Valve stem: It is the component that connects the valve plate and operating mechanism. Usually made of metal materials with good mechanical properties and corrosion resistance. The design of the valve stem needs to take into account its stability and sealing in high temperature and high pressure environments.

Seal: Located between the valve body and valve plate, it is used to prevent fluid leakage. Usually made of rubber, polytetrafluoroethylene and other materials, it has good sealing performance and corrosion resistance. In some high temperature and high pressure applications, metal sealing rings or carbide sealing rings can also be used, check valve factory.

Operating mechanism: including handwheel, handle, electric actuator, etc., used to control the switching action of the valve. The design of the operating mechanism needs to take into account the use conditions and safety requirements of the valve.

Jacketed nozzles and flanges: used to connect inlet and outlet pipes for cooling or heating media. The design of jacketed nozzles and flanges needs to take into account factors such as the temperature, pressure and flow rate of the medium to ensure their sealing and reliability.

4. Advantages and application areas of jacketed gate valves

High temperature and high pressure applications: Because the jacketed gate valve has a jacket structure and can be used to inject cooling or heating media, it is suitable for high temperature and high pressure applications. For example, in the petrochemical industry, jacketed gate valves are often used to control the flow of high-temperature and high-pressure fluids, such as steam, thermal oil, etc.

Precise control of medium temperature: By adjusting the flow rate and temperature of the cooling or heating medium in the jacket, the temperature of the medium inside the valve can be accurately controlled. This is very important in certain processes that require precise temperature control, such as chemical reactions, heat exchange, etc.

Good sealing performance: The jacketed gate valve uses high-quality sealing rings and materials and has good sealing performance. Even in high temperature and high pressure environments, it can effectively prevent fluid leakage and ensure the safety and reliability of the process, wholesale globe valve.

Wide range of applications: Jacketed gate valves are widely used in many industries, such as petrochemical industry, steel metallurgy, electric power, pharmaceuticals, etc. In these industries, jacket gate valves play an important role, providing a strong guarantee for the smooth progress of the process.

Ease of Maintenance and Inspection: Jacketed gate valves are usually designed with ease of maintenance and inspection in mind. Through reasonable structural design and material selection, the maintenance cost of the valve can be reduced and the service life can be improved. At the same time, the disassembly and installation of the jacketed gate valve are relatively convenient, which is conducive to rapid maintenance and replacement of the project.

Environmental performance: With the improvement of environmental awareness and increasingly strict environmental regulations, the environmental performance of the valve industry has attracted more and more attention. The jacketed gate valve fully considers environmental protection requirements during the design and manufacturing process, and uses environmentally friendly materials and coating technology to reduce the valve's impact on the environment. In addition, the jacketed gate valve also has the characteristics of energy saving and consumption reduction. By optimizing the design and manufacturing process, the energy consumption and leakage rate of the valve during operation can be reduced, thereby reducing the negative impact on the environment and saving operating costs for the enterprise.
