液壓貨梯的閥門低溫試驗裝置主要用來進行低溫閥門零部件深冷處理和閥門低溫型式試驗，閥門低溫試驗裝置是液壓貨梯經(jīng)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.

液壓貨梯的閥門低溫裝置主要零部件在精加工前應(yīng)進行深冷處理，目的是減少由于溫差和金相組織改變而產(chǎn)生的變形，低溫試驗主要是檢驗在低溫工作環(huán)境下，低溫閥門的整機性能，這是一項要定期進行的工作。
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.
