Advantages of check valve

1. High reliability: check valve structure is simple, easy to maintain, has good sealing and reliability, not easy to fail.

2. Energy saving: relying on the material itself as the medium pressure difference to achieve opening and closing, do not need additional power equipment, can save energy.

3. High safety: check valve can effectively prevent media backflow and pipeline burst and other accidents, play a role in safeguarding equipment and personal safety.

4. Economical and practical: check valve low cost, simple operation, long service life, widely used in a variety of media flow pipeline system.

Disadvantages of check valve

1. Large resistance: check valves form a relatively closed space at the valve, which will produce a certain resistance in the piping system and increase the energy consumption of the piping system.

2. Pressure loss: In industrial production, the pressure of the piping system varies greatly, which easily leads to excessive pressure loss when the check valve is working, affecting the stability of the piping system.

3. Cleaning is not easy: the internal structure of the check valve is more complex, after a period of time, there will be a certain amount of dirt and sediments inside the valve, cleaning and maintenance is more difficult.

Application Scope of Check Valves

Check valve is suitable for liquid, gas and steam and other media piping system, mainly used in the following areas:

1. water pipelines, to ensure the safety of water quality.

2. heating system, to prevent pump backflow.

3. petroleum, chemical, metallurgy, light industry and other industrial areas of the production process, for pipeline media one-way flow.

4. boiler system of thermal power plant, to ensure one-way flow of water and prevent explosion.

The use of check valves

1. Installation position: check valve in the pipeline system should be used to choose the appropriate location, usually installed at the end of the pipeline or the need to protect the one-way flow of the key position.

2. Installation: check valves should be installed according to the nature of the medium to choose the appropriate material and structure, different types of check valves also have ball valves, butterfly valves, rotary, lifting, rubber core and other different installation methods.

3. Maintenance: In the course of use, regular cleaning and maintenance should be carried out to ensure the normal operation of the check valve.

The development direction of check valve

At present, with the rapid development of the industrial field and the continuous progress of technology, check valves are also constantly innovating. The future development direction mainly includes:

1. Improvement of manufacturing materials: use more advanced manufacturing materials and technology to improve the service life and performance of check valves.

2. Optimisation of structural design: through the improvement of structural design, reduce the resistance and pressure loss of the check valve in the piping system.

3. Intelligent development: combining new technologies such as Internet of Things, cloud computing, etc., to achieve remote monitoring and control of the check valve, and improve the automation of industrial production.
