Valve Testing Bench-the key equipment to ensure industrial valve quality and performance

1. Introduction of the Valve test benches / Valve testing equipments 

In the modern industrial field, valves are the key components to control fluid flow, and the reliability of their performance and quality is essential.In order to ensure the normal operation of the valve under various working conditions, the valve testing machine/ Valve testing benches came into being.It is a kind of equipment specially used for performance testing and quality evaluation of valves, and plays an indispensable role in the production, installation and maintenance of valves industry.

2. The working principle of the valve testing benches 

The valve testing benches mainly performs various performance tests on the valve by simulating the pressure, temperature, flow and other parameters in the actual working environment.It usually consists of a pressure control system, a temperature control system, a flow control system, a test fixture, and a data acquisition and analysis system.During the test process, the valve is installed on the test fixture( Sealing plates or adaptors), a certain pressure is applied through the pressure control system( According to the related valve inspection standard) , and the sealing performance, opening and closing performance, strength and other indicators of the valve are observed.At the same time, the temperature control system and the flow control system can simulate different operating temperature and flow conditions to comprehensively evaluate the performance of the valve.

3. The main types of valve testing benches 

Hydrostatic valve test benches : It is mainly used to test the performance of the valve in the water pressure environment( testing medium by water) , such as sealing performance and shell test .Hydrostatic testing machines can usually provide higher pressures to meet the testing requirements of different types of valves.

Air pressure valve test benches:  Suitable for testing the performance of gaseous medium valves, such as ball valves, butterfly valves, etc.The air pressure tester can accurately control the air pressure to detect the sealing performance and operating performance of the valve under different air pressure conditions. ( testing medium by air or other gas like nitrogen). 

Hydraulic valve testing benches: Used to test valves used in hydraulic systems, such as globe valves, reversing valves, etc.The hydraulic testing machine can simulate the pressure and flow conditions in the hydraulic system to evaluate the performance of the valve in the hydraulic system.

Comprehensive valve testing benches : A valve testing machine that integrates various testing functions such as water pressure, air pressure, and hydraulic pressure, which can meet the comprehensive testing needs of different types of valves.Comprehensive testing machines usually have a higher degree of automation and testing efficiency, which can greatly improve the efficiency of valve testing.

According to the test benches clamping features, the valve testing benches also can be devided into : 

Horizontal type valve test bench, vertical type valve test bench, tilting type valve test bench and submerged type valve test bench( With big water tank).

4. The application field of valve testing machine

Valve manufacturers: In the valve production process, valve testing machines are used to conduct strict performance tests on each batch of valves to ensure that product quality meets relevant standards and customer requirements.

Petrochemical industry: Valves used in the petrochemical industry need to withstand harsh conditions such as high temperature, high pressure, and corrosive media. Therefore, high-precision valve testing machines need to be used to evaluate the performance of the valves to ensure their safe and reliable operation in the petrochemical production process.

Powerplant industry: The valves used in the power industry are mainly used to control the flow of steam, water, oil and other media, such as globe valves, regulating valves, etc.The use of valve testing machines to perform performance tests on these valves can ensure their stable operation in the power production process.

Urban water supply and sewage treatment industry: The valves used in the urban water supply and sewage treatment industry need to have good sealing performance and corrosion resistance. The use of valve testing machines to test the performance of these valves can ensure their safe and reliable operation in the process of water supply and sewage treatment.

5. The development trend of valve testing benches 

Intelligence: With the continuous development of science and technology, valve testing machines will become more and more intelligent.The intelligent valve testing machine can realize functions such as automatic testing, data collection and analysis, and fault diagnosis, greatly improving the testing efficiency and accuracy.

High precision: In order to meet the testing needs of high quality valves, valve testing benches will develop in the direction of high precision.High-precision valve testing machines can provide more accurate test data and provide a more reliable basis for valve research and development and production.

Multi-function: In order to meet the testing needs of different types of valves, the valve testing machine will develop in the direction of multi-function.The multifunctional valve tester can perform a variety of performance tests at the same time, such as sealing performance, opening and closing performance, strength, etc., which greatly improves the test efficiency.

Portability: With the increase of on-site testing requirements, valve testing machines will develop in the direction of portability.The portable valve tester is small in size, light in weight, and easy to carry, so it can be easily tested on site.

6. Conclusion

As the key equipment to ensure the quality and performance of valves, valve testing benches play an important role in the modern industrial field.With the continuous development of science and technology and the continuous changes in industrial demand, Dory valve testing machines will continue to innovate and develop to provide more reliable technical support for the development of the valve industry.In future industrial production, valve testing machines will continue to play an important role and make greater contributions to ensuring the safe and reliable operation of industrial production.
