Operational capacity test device of low-temperature pressure gloves

Abstract

The invention relates to an operational capacity test device of a pair of low-temperature pressure gloves, comprising a vacuum system, a refrigerating system and a temperature measuring system. The operational capacity test device is characterized in that the vacuum system comprises a vacuum pump and a piezoresistive vacuum gauge; the refrigerating system comprises a pressure Dewar flask and a low-temperature pressure chamber; the temperature measuring system comprises a temperature sensor, a logging device and a computer; wherein air in the low-temperature chamber is extracted by the vacuum pump so as to realize differential pressure inside and outside the gloves; a low-temperature environment of the low-temperature pressure chamber is realized by liquid-nitrogen cooling in the pressure Dewar flask; the temperature measuring system is used for acquiring, monitoring at the real time, recording temperature values of all temperature-measuring points and ensuring that the measuring temperature reaches technical requirements. The operational capacity test device can not only satisfy pressure and visual requirements on a normal-temperature pressure test device, but also provide a low-temperature test environment from the normal temperature to -100 DEG C according to test requirements, realize the low-temperature pressure two-factor environment and carry out the operational capacitytest on the gloves under the pressure condition.

Description

(1) Technical field: [0001] The invention relates to a test device mainly used for testing the working ability of gloves with internal and external pressure difference in a low temperature environment. (two) background technology: [0002] When there is a pressure difference between the inside and outside of the glove, it will have a greater impact on the working ability of the glove, especially in low temperature environments. However, there is only a normal temperature and pressure test device in the world, and there is no glove operating ability test device that can provide low temperature and pressure dual-factor operating environment. The invention can not only meet the pressure and visual requirements of the normal temperature pressurized test device, but also provide a low temperature glove operating ability test environment from normal temperature to -100 DEG C according to the test requirements. (3) Contents of the invention: [0003] The purpose of the present i...
