Description

technical field

[0001] The invention relates to the technical field of test products, in particular to a low-pressure environment test box. Background technique

[0002] Low pressure test system (or test chamber) is widely used in aviation, aerospace, information, electronics and other fields, mainly used to test instruments, electrical products, materials, parts or equipment under the single or simultaneous action of low pressure, high temperature and low temperature. Environmental adaptability and reliability test. For example, the low-pressure test system (or test chamber) can simulate special conditions such as plateau altitude climate or high-altitude climate, place the test sample in it, and perform corresponding performance tests on the test sample. The sealing performance of the low-pressure environment test chamber is very important. , which is related to the accuracy rate of the performance test. According to the prior art, the sealing performance of the low-press...
