1. Design structure and working principle

Cryogenic gate valve, as a commonly used cut-off valve, is mainly used to cut off or connect the flow of media in pipelines. Its design and structure are unique and mainly consists of valve body, gate plate, valve stem and sealing ring. Among them, the design of the gate is the key, and its shape and size directly affect the sealing performance and fluid dynamics performance of the valve.

In terms of working principle, the cryogenic gate valve relies on the lifting and lowering of the gate to control the flow of the medium. When the gate is raised, the medium can flow through the valve; when the gate is lowered, the valve is closed, preventing the flow of the medium. This working principle makes the cryogenic gate valve have good shutoff performance and small fluid resistance.

2. Material selection and manufacturing process

The materials used to manufacture low-temperature gate valves must have excellent mechanical properties, corrosion resistance and low-temperature properties. Commonly used materials include stainless steel, carbon steel, low alloy steel and special alloys. When selecting materials, factors such as the nature of the medium, working pressure and temperature need to be considered, bronze wafer check valve.

In terms of manufacturing process, the manufacturing of cryogenic gate valves requires multiple processes, including casting, forging, heat treatment, machining and assembly. Each process requires strict quality control to ensure that the performance and quality of the product meet the design requirements. In particular, the processing and installation of sealing rings are the top priority, which directly affects the sealing performance of the valve.

3. Practical applications and advantages

Cryogenic gate valves are widely used in petroleum, chemical, natural gas and other industries, and are mainly used to cut off or connect the flow of media in pipelines. In these industries, the medium often has characteristics such as high pressure, high temperature, and high corrosivity. Therefore, valves are required to have excellent sealing performance, corrosion resistance, and high temperature and high pressure performance. The cryogenic gate valve exactly meets these requirements and has the following advantages:

Excellent sealing performance: The low-temperature gate valve adopts a unique sealing ring design, which can achieve zero leakage and effectively prevent safety hazards caused by medium leakage.
Good fluid dynamic performance: The design of the gate allows the medium to have less resistance when flowing through the valve, thereby reducing energy consumption and operating costs.
Strong corrosion resistance: Made of corrosion-resistant materials, it can be used for a long time in harsh environments without damage, high temperature check valve.
Broad scope of application: It is suitable for various media, working pressure and temperature conditions, and can meet the needs of different industries.

4. Technological Innovation and Development Trends

With the advancement of science and technology and the development of the industry, technological innovation of cryogenic gate valves is also constantly advancing. On the one hand, the application of new materials and new processes has continuously improved the performance and quality of cryogenic gate valves; on the other hand, the development of intelligent and automation technology also provides the possibility of intelligent and automated control of cryogenic gate valves.

In the future, the development trend of cryogenic gate valves will be mainly reflected in the following aspects: first, high performance, that is, improving the sealing performance, corrosion resistance and high temperature and high pressure performance of the valve; second, intelligence and automation, that is, realizing remote control of the valve , automatic monitoring and maintenance functions; the third is green environmental protection, that is, the development of environmentally friendly materials and processes to reduce environmental pollution during the manufacturing and use of valves, socket weld check valve.
