China check valve working principle analysis: one-way flow, prevent reverse flow

China check valve is a commonly used fluid control equipment, its working principle is one-way flow, prevent reverse flow. This article will analyze the working principle of China’s check valve from a professional perspective.

1. Definition and role

China check valve is a valve device that can prevent the flow of fluid in the opposite direction. Its main function is to prevent the backflow of fluid in the pipeline system and ensure that the fluid can only flow in one direction. The Chinese check valve is usually installed at the entrance or exit of the pipeline to control the direction and flow of the fluid.

2. How it works

The working principle of China check valve is based on many factors such as gravity, spring force, electromagnetic force and so on. Generally speaking, Chinese check valves are composed of body, valve cover, valve disc, spring and other parts. When the fluid enters the China check valve from the inlet, due to the action of gravity and spring force, the valve disc will close the valve, so that the fluid can only flow in one direction. When the fluid flows in reverse, due to the position of the disc and the action of the spring, the disc will open the valve so that the fluid can continue to flow in reverse.

3. Classification and characteristics

According to different structural forms and use occasions, Chinese check valves can be divided into many types, such as lifting Chinese check valves, rotary Chinese check valves, butterfly Chinese check valves and so on. Different types of Chinese check valves have different characteristics and scope of application. For example, the lift type China check valve is suitable for large diameter pipeline system, the butterfly type China check valve is suitable for middle and low pressure pipeline system, and the rotary type China check valve is suitable for high pressure and high temperature environment.

4. Application field

China check valve is widely used in the pipeline system of petroleum, chemical, metallurgy, electric power, light industry, food and other industries. It can effectively control the direction and flow of the fluid to ensure the normal operation of the pipeline system. In addition, the Chinese check valve can also be used to prevent the reverse operation of the pump and protect the normal operation of the equipment.

In short, the working principle of China’s check valve is one-way flow to prevent reverse flow. Different types of Chinese check valves have different characteristics and scope of application, and are widely used in various pipeline systems. I hope this article analyzes the working principle of China’s check valve and can provide you with some reference and help.
