The main function of a breathing valve is to balance the pressure inside and outside the container, preventing equipment damage caused by overpressure or over vacuum. The breathing valve test bench is a professional equipment designed to test and verify the performance of breathing valves, widely used in fields such as petrochemicals, tank manufacturing, and pressure vessel industry. The breathing valve test bench conducts comprehensive testing and evaluation of various performance indicators of the breathing valve by simulating real working conditions.
The breathing valve test bench usually sets different pressure conditions (positive pressure and negative pressure) and monitors the response of the breathing valve in real time. The test bench can control the rate of pressure rise or fall to test the opening and closing pressure of the breathing valve. In addition, by simulating conditions such as pressure difference and flow rate changes inside and outside the storage tank, the test bench can evaluate the performance of the breathing valve under various working conditions. The breathing valve calibration bench can be used in various production enterprises to use the test bench for quality control during the production process, ensuring that the performance of each breathing valve meets the design requirements. Petrochemical companies regularly inspect the breathing valves in storage tanks to prevent potential equipment failures and safety hazards. Research institutions and certification bodies are used to test the development and performance certification of new breathing valves.
The breathing valve test bench mainly tests the various performance of the breathing valve to display its various states, including the following.
Open pressure test: measure the pressure value at which the breathing valve starts to open under positive or negative pressure conditions. This is a key indicator to ensure that the valve can operate within the correct pressure range.
Close pressure test: Evaluate whether the breathing valve can effectively close after the pressure drops, and measure the pressure value when it closes to ensure that the valve will not open or close under inappropriate pressure.
Sealing performance test: Under negative pressure conditions, check for leaks in the breathing valve. This is crucial for the safety of storage tanks, especially for storage containers for toxic or flammable media.
Flow test: Measure the flow rate of the breathing valve in the open state to ensure that it can operate normally within the designed flow range. This usually involves testing the flow capacity and flow resistance characteristics of the valve.
The components of the breathing valve test bench mainly include the following key components to ensure comprehensive and accurate testing of various performance indicators of the breathing valve.
Pressure control system: used for precise control of test pressure, including adjustment of positive and negative pressure. Usually equipped with high-precision pressure sensors and regulating valves.
Flow measurement system: Record the flow data of the breathing valve under different pressure conditions through flow sensors and measuring instruments.
Data acquisition and control system: an integrated software system used for real-time monitoring and recording of various data during the testing process, and generating detailed testing reports. This system usually has functions such as data storage, analysis, and export.
Safety protection system: To ensure safety during the testing process, the test bench is usually equipped with various safety devices, such as pressure relief valves, emergency stop buttons, leak detectors, etc.
The breathing valve test bench is usually equipped with a human-machine interface or computer control interface, and operators can set test parameters, start testing, and view real-time data through an intuitive interface. In order to ensure the accuracy of the test results, the pressure sensors, piping system, control valves, sensors and other components of the test bench need to be regularly inspected and maintained to ensure their long-term stable operation.
The breathing valve test bench plays an important role in industrial production and quality control. By simulating various working conditions, it comprehensively tests the performance of breathing valves to ensure their safety and reliability in practical applications.
