Where is the pressure valve test

Pressure vessels with pressure valve testing Foshan valve testing

First, pressure detection

Pressure detection is one of the most common pressure valve detection methods, usually used to test whether the opening and closing pressure values of the pressure valve meet the design requirements. The specific steps are as follows:

1. Preparation: Prepare the pressure gauge, control valve and bucket (or other media bucket).

2. Interface installation: Connect the pressure gauge to the inlet and outlet interface of the pressure valve, and install the control valve to control the flow of the medium.

3. Build the experimental platform: place the bucket or other media bucket in the appropriate position and connect it with the control valve.

4. Experimental operation: Open the media in the bucket or media bucket so that it flows into the pressure valve, adjust the control valve to make the medium flow appropriate, and record the pressure value when the pressure valve is opened and closed.

Second, traffic detection

Flow detection is used to detect the maximum flow capacity of the pressure valve, which is usually used for pressure valves with relatively large specifications. The specific steps are as follows:

1. Preparation: Prepare the flow meter, pressure gauge, control valve and media barrel.

2. Interface installation: Connect the flow meter and pressure gauge with the inlet and outlet interface of the pressure valve, and install the control valve to control the flow of the medium.

3. Build the experimental platform: place the medium barrel in the appropriate position, connect it with the flow meter and pressure valve, and switch on the power supply.

4. Experimental operation: Open the outlet of the media barrel, adjust the control valve to make the media flow appropriate, record the flow value of the pressure valve when it is working, and compare it with the rated flow value of the pressure valve.

3. Leak detection

The leak detection method is usually used to detect the internal and external leakage of the pressure valve, which is suitable for conveying high pressure, high temperature, toxic and flammable media. The specific steps are as follows:

1. Preparations: Prepare pressure gauges, valve leak detection agents, watering cans and protective equipment.

2. Interface installation and spraying detection agent: Connect the pressure gauge with the inlet port, spray the detection agent around the valve, and observe whether there is leakage.

3. Detection operation: Open the control valve to make the medium flow, observe whether there is leakage, and take appropriate measures to eliminate it in time.

In general, the above three pressure valve detection methods have their own scope of application, and the specific use needs to be selected according to demand. The necessary testing of the pressure valve can ensure its stable and reliable work, and plays an important role in preventing accidents.
