China stop valve working principle detail: cut off or connect the fluid channel
Chinese globe valve is a commonly used fluid control equipment, its working principle is to realize the control of the fluid by shutting off or connecting the fluid channel. This article will give you a detailed introduction to the working principle of China’s globe valve from a professional perspective.
1. How it works
The main function of the stop valve is to cut off or connect the fluid channel in the pipeline to control the flow rate and pressure of the fluid. When the Chinese stop valve is closed, the fluid cannot pass through the valve; When the Chinese stop valve is open, fluid can pass through the valve.
The working principle of the Chinese globe valve is based on the structure of the piston or the elevator. When the medium (such as gas or liquid) passes through the Chinese stop valve, the pressure of the medium will make the piston or the elevator move down, which will press the sealing surface of the valve at both ends of the channel and prevent the flow of the medium. When it is necessary to open the valve, just lift the piston or the elevator upward to make the sealing surface leave the two ends of the channel to make the medium flow.
2. Classification and characteristics
According to the different structure and use, Chinese globe valves can be divided into straight-through type, Angle type, three-way type and other types. Different types of Chinese globe valves have different characteristics and scope of application.
(1) Straight-through Chinese globe valve: Straight-through Chinese globe valve is the most commonly used type of Chinese globe valve, which has simple structure, convenient manufacture and low price. Straight-through Chinese globe valve is suitable for low pressure, large flow fluid control applications.
(2) Angle Chinese globe valve: Angle Chinese globe valve is a common Chinese globe valve type, its structure is more complex, but has better sealing performance and adjustment performance. Angle Chinese globe valve is suitable for high pressure, small flow fluid control applications.
(3) Three-way Chinese globe valve: The three-way Chinese globe valve is a multi-functional Chinese globe valve type that can be used to control three directions of the fluid channel. The three-way Chinese globe valve is suitable for applications where more than two fluid channels need to be controlled simultaneously.
In short, different types of Chinese globe valves have different characteristics and scope of application, and the appropriate type of Chinese globe valves should be selected according to the specific working conditions and use requirements. I hope the introduction of this article can provide you with some reference and help.
