Chinese gate valve, Chinese globe valve and Chinese check valve: in-depth analysis of their respective functions and uses
Chinese gate valves, Chinese globe valves and Chinese check valves are three common valve types, each with different functions and uses. Below we will analyze the characteristics and application scenarios of these three valves in depth.
Chinese gate valve is a vertical motion valve, its main function is to cut off the fluid in the pipeline. The working principle of the Chinese gate valve is to open or close the channel through the sealing match between the gate and the seat, so that the gate moves vertically along the axis of the channel. Chinese gate valves are usually used in situations where pipes need to be cut off quickly, such as boilers, heating systems, etc. In addition, the Chinese gate valve also has a certain adjustment function, and the flow of the fluid can be adjusted by adjusting the lift of the gate.
The advantages of China gate valve: simple structure, small size, light weight, easy operation, good sealing performance, simple maintenance. Disadvantages: large fluid resistance, slow opening and closing speed, can not be used for large diameter pipelines.
The Chinese globe valve is also a vertically moving valve, and its main function is to prevent the fluid in the pipeline from flowing in one direction while allowing the fluid to flow in the other direction. The working principle of the Chinese globe valve is to rotate the hand wheel or electric device, so that the valve stem drives the valve disc to rotate along the axis of the channel, so as to realize the opening and closing of the valve. Chinese globe valves are usually used in situations where the flow of fluid needs to be controlled, such as hot water systems, steam systems, etc.
The advantages of China globe valve: simple structure, easy operation, good sealing performance, simple maintenance. Disadvantages: large fluid resistance, slow opening and closing speed, can not be used for large diameter pipelines.
China check valve is an automatic working valve, its main function is to prevent the flow of fluid in the pipeline backflow. The working principle of the Chinese check valve is to use the pressure difference of the fluid and its own spring force to make the valve disc open and close automatically. China check valves are usually used in situations where fluid backflow needs to be prevented, such as tap water systems, chemical production, etc.
The advantages of China check valve: simple structure, automatic work, good sealing performance, simple maintenance. Disadvantages: small fluid resistance, fast opening and closing speed, can not be used for large diameter pipelines.
In SUMMARY:
China gate valve, China globe valve and China check valve each have different functions and uses. China gate valve is mainly used to cut off the fluid in the pipeline, China stop valve is mainly used to control the flow of fluid, and China check valve is mainly used to prevent fluid backflow. When selecting the valve, the appropriate valve type should be selected according to the actual engineering needs and the use environment.
