液压货梯的阀门低温试验装置主要用来进行低温阀门零部件深冷处理和阀门低温型式试验，阀门低温试验装置是液压货梯经常使用的。
Cryogenic valve test equipment mainly used for hydraulic freight elevator cryogenic processing and cryogenic valve type test, low temperature test equipment cryogenic valves valve parts are frequently used hydraulic freight elevators.
液压货梯的阀门低温装置主要零部件在精加工前应进行深冷处理，目的是减少由于温差和金相组织改变而产生的变形，低温试验主要是检验在低温工作环境下，低温阀门的整机性能，这是一项要定期进行的工作。
The main parts of the hydraulic valve cryogenic device freight elevator before finishing cryogenic treatment should be carried out, in order to reduce distortion due to changes in temperature and microstructure produced, low temperature test mainly aimed at testing the working environment at low temperatures, the overall performance of cryogenic valves this is a work to be carried out regularly.
