Structure and working principle of valve test bench

Mar 25, 2025

The valve test bench is used to test the performance of the valve and is an important piece of equipment, its structural design and working principle to ensure the accuracy and reliability of the test is critical.

1. The structure of the valve test bench

Pressure source system: this is to provide the key part of the test pressure, usually including high-pressure pumps, tanks, and other equipment, able to produce a stable pressure.

Test chamber: used to accommodate the valve being tested, chamber design to be able to adapt to different types and sizes of valves.

Sealing device: to ensure that the medium will not leak during the test process, and to ensure the sealing performance of the test environment.

Control system: including electrical control cabinet, operating panel, etc., used to control the test process parameters set, start and stop operations.

Data acquisition system: real-time collection and recording of various data in the test process, such as pressure, flow, time, etc..

2. The working principle of the valve test bench

Pressure test principle: through the pressure source system to the test chamber to inject high-pressure media, so that the valve to withstand a certain pressure, and then observe whether the valve leakage or deformation and so on.

Sealing performance test principle: the use of sealing devices to seal the valve, and then through pressure changes or other detection methods to determine the sealing performance of the valve.

Flow test principle: simulate the actual working conditions in the test chamber, through the measurement of the flow of media through the valve to assess the flow characteristics of the valve.

Action performance test principle: through the control system to control the switching action of the valve, to observe whether the valve action is flexible, accurate, and response time and other performance indicators.

In the test process, the test bench will carry out a series of tests on the valve in accordance with the preset procedures and parameters, and at the same time, the test data will be transmitted in real-time to the data acquisition system for recording and analysis. Through the analysis and comparison of these data, a comprehensive understanding of the valve's performance status provides a basis for quality assessment and improvement of the valve.

The structure and working principle of the valve test bench are interrelated and cooperate with each other to jointly achieve accurate detection and evaluation of valve performance. With the continuous progress of technology, the performance and function of the valve test bench are also constantly improving, providing strong support for the development of the valve industry.
