Vacuum coating machine pressure solenoid valve helium leak detection system

           

Leak vacuum coating machine high pressure solenoid valve, such as gas stations or hydrogen for industrial gases used in the tunnel for the high-pressure solenoid valve products for leak detection rate is a very challenging task. To ensure that hydrogen does not overflow valve, which requires a very low leakage rate to test the product, or its leak rate greater than 1 × 10-6 mbar l / sec. After comparison test: The leak rate range than we see bubbling escaped from the water leakage rate of air (in the water naked eye is approximately equal to the maximum air foam 10-3 mbar l / sec) but also much lower.

Leak detection systems customized technical requirements of the road:

1, the pressure valve between 0.5 ~ 360 bar. All tests required to complete in the fully automated environment.

2, sustainable and free choice test to measure gas concentration test gas recovery system. Technical Requirements Background: If a valve is filled with helium, the helium is then continuously charged will be reduced. About 180 liters of helium in a pressure 360 bar and an internal valve capacity of 0.5 liters a round robin test system is released. As the gas production process is complicated and cost, helium is an expensive test gas. Test gas recovery system can bring more benefit from the economic and ecological aspects. Recycling and utilization can reach more than 95%.

3, in order to ensure that the test pressure of 360 bar or more in the calibration and to avoid any possible pressure peaks, it is necessary to develop a pressure up to 500 bar high pressure comparison system, which buffer vessel a test gas requires special storage means, in order to gradually release the downward gas.

4, will also need an additional function valve testing system: nitrogen pressure 100bar over when the pressure from the valve can flow into the atmosphere. This process flow will reach 2.5 times the speed of sound, the result is a tremendous noise, which must require a special silencer.
