Abstract

The invention relates to the technical field of low-temperature safety valve performance tests, and particularly relate to a low-temperature safety valve performance test system and a test method. Thesystem comprises a temperature adjustment assembly, a pressure adjustment assembly, a detection assembly and a shell-and-tube heat exchanger assembly, the shell pass inlet of the shell-and-tube heatexchanger assembly is connected with one end of a test medium input pipeline, and the pressure adjustment assembly is arranged on the test medium input pipeline; the shell pass outlet is connected with one end of the detection pipeline, a to-be-detected safety valve is arranged at the other end of the detection pipeline, the detection assembly is arranged on the detection pipeline at the shell pass output end, and the temperature adjustment assembly is arranged at the tube pass inlet and outlet of the shell-and-tube heat exchanger assembly. The system provided by the invention has the advantages that the shell-and-tube heat exchanger assembly is used, the pressure needed by a test is achieved through the shell pass and the pressure adjustment assembly, and the temperature needed by the test is achieved through the tube pass and the temperature adjustment assembly.

Description

technical field [0001] The invention relates to the technical field of low temperature safety valve performance test, in particular to a low temperature safety valve performance test system and test 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 valve for cryogenic medium and BS EN 13648-1:2008 Cryogenic vessels-Safety devices for protection against excessive pressure-Part 1: Safety valves for cryogenic service, two Both have recommended a method of increasing the pressure of the test medium by using the sel...
