Low temperature valve test and inspection
Low temperature valve test and inspection:

The main parts of the low temperature valve are processed at low temperature and each batch is sampled for low temperature impact test to ensure that the valve is not brittle and can withstand low temperature medium impact under low temperature conditions.

Conduct the following tests for each cryogenic valve:

1. Shell strength test at room temperature;

2. Upper sealing test at room temperature and low pressure;

3. Normal temperature and low pressure sealing test;

4. Air tightness test of upper seal at low temperature (with upper seal);

5. Low temperature gas seal test, etc., to ensure that the whole low temperature valve meets the standard provisions;

6. The main parts of the low temperature valve are processed at low temperature and each batch is sampled for low temperature impact test to ensure that the valve is not brittle and can withstand low temperature medium impact under low temperature conditions;

7. Low temperature (cryogenic) valves are processed in low temperature and impact test according to the corresponding material specifications

8. The electrostatic function is more powerful, the conduction resistance between the valve body and the valve stem or the inner parts and the valve body is less than 1 ohm.
