Embodiment 2
[0043] Using the test method of a low-temperature safety valve performance test system described in Example 1, the setting test in the performance test includes the following steps:
[0044] S1, system purging; sequentially open the heat exchanger emptying valve 21, the shell side inlet valve 17 on the shell side of the heat exchanger 20, the storage tank outlet valve 132 in the pressure regulating assembly, the storage tank inlet valve 131, The gas cylinder valve 110, adjust the opening of the test medium flow control valve 15, ensure that the test medium input pipeline, the shell side of the heat exchanger, and the atmosphere are in a conducting state, and start the booster pump 12. At this time, the test medium supply module supplies air to the system, After the set time, stop the air supply of the test medium supply module, and close the heat exchanger emptying valve 21;
[0045] S2, respectively providing a high-pressure test medium environment and performing a pre-coolin...

The invention relates to the technical field of low temperature safety valve performance testing, and in particular to a low temperature safety valve performance testing system and testing method. The shell-side inlet of the shell-and-tube heat exchanger assembly is connected to one end of the test medium input pipeline, and the pressure regulating assembly is arranged on the test medium input pipeline; the shell-side outlet is connected to one end of the detection pipeline, and the safety valve to be tested is set at the test medium input pipeline. At the other end of the pipeline, the detection component is arranged on the detection pipeline of the shell side output end, and a temperature adjustment component is arranged at the tube side inlet and outlet of the shell and tube heat exchanger component. The advantages of the invention are: the present invention uses the shell-and-tube heat exchanger assembly to realize the pressure required for the test through the shell side and the pressure regulating assembly, and realize the temperature required for the experiment through the tube side and the temperature adjustment assembly.
Description
technical field [0001] The invention relates to the technical field of low temperature safety valve performance testing, in particular to a low temperature safety valve performance testing system and a testing method. Background technique [0002] Cryogenic safety valves are widely used in the field of cryogenic engineering. As an important safety accessory, the cryogenic safety valve is crucial to the safe operation of the system. Compared with the safety valve used at normal temperature, the performance test of the low temperature safety valve is mainly based on the sealing performance test and the setting test. [0003] The current domestic and foreign standards mainly include GB / T 29026-2012 spring direct load safety valves for cryogenic media and BS EN 13648-1:2008Cryogenic vessels-Safety devices for protection againstexcessive pressure-Part 1:Safety valves for cryogenic service, two Both recommended a method to increase the pressure of the test medium by using the se...
