The types and application fields of check valves are introduced in detail

Check valve is a valve to prevent media backflow and protect the safety of the pipeline, its main function is to ensure that the fluid in the pipeline one-way flow, while preventing media backflow to the equipment damage. Check valves can be divided into various types according to different structures and functions. The following Lyco valves will introduce the types and application fields of check valves.

Type of check valve

1. One-way check valve

The one-way check valve is a simple type of check valve that is installed in the pipe to prevent dielectric backflow and counterflow. One-way check valves are divided into ball type, butterfly type, full open type, bottom discharge type and other types. Different types of one-way check valves are suitable for different working conditions, such as high temperature, high pressure, explosion risk and so on.

2. Reverse water check valve

Reverse water check valve is a kind of check valve based on the elastic principle, also known as flip plate check valve. When the medium flows normally, the valve is open and the medium can pass freely. When media backflow occurs, the flap valve disc will quickly close to prevent media backflow and protect related equipment.

3. Swing check valve

Swing check valves include piston swing check valves and butterfly type swing check valves. The swing check valve is connected to the transmission device through the nut. It is suitable for large diameter pipelines and high pressure, high temperature, and frequent adjustment of medium flow.

Application field of check valve

1. Petrochemical industry: Check valves can be applied to oil fields, oil refining, chemical industry and other fields in the petrochemical industry, which plays an important role in preventing the countercurrent of dangerous media such as oil and gas and chemical products and ensuring the safety of production.

2. Food and beverage industry: The check valve is suitable for the production process of the food and beverage industry, which can prevent the countercurrent of the medium, avoid cross contamination, and ensure the production health.

3. Water and sewage treatment industry: In the water and sewage treatment industry, check valves can be installed in pipes to effectively prevent sewage backflow and protect wastewater treatment plants and plumbing equipment.

4. Building and heating industries: Check valves can also be used in building and heating industries to provide effective backflow protection for equipment and pipes in hot water circulation systems, heating systems and water supply systems.

In short, the check valve has a wide range of applications in different fields and working conditions, and plays an important role in ensuring the one-way flow of media and protecting the safety of pipeline equipment. Lyco Valves manufactures and sells all kinds of check valves to help customers achieve efficient, accurate and stable fluid control.
