Abstract

The invention discloses a low-temperature testing tank, which comprises a box body with an opening facing upward and a heat preservation upper cover arranged at the upper end of the box body, wherein the box body comprises an inner container and an outer container, the inner container is sheathed in the outer container, and the part between the inner container and the outer container is filled with a foam material. The low-temperature testing tank is characterized in that the outer container comprises a side plate, a bottom plate and an L-shaped support base, one end of the L-shaped support base is fixedly connected with the bottom plate, the other end of the L-shaped support base is provided with a sliding slot extending along the vertical direction and is movably connected with the side plate through a bolt penetrating through the sliding slot, and the side plate can move up and down relative to the bottom plate. The testing tank can solve a problem bending deformation, which is caused by a low temperature, of the outer container, so that the sealing performance of the testing tank is ensured.

Description

technical field [0001] The invention relates to the technical field of low temperature test devices, in particular to a low temperature test tank. Background technique [0002] With the rapid development of industries such as air separation, liquefied natural gas and ethylene petrochemicals, the application of cryogenic valves is becoming more and more extensive. In order to ensure the safe and reliable operation of valves at low temperatures, mechanical strength and heat transfer must be considered during the design process. Require. [0003] Cryogenic valves must not only work normally at room temperature, but also work normally at low temperatures. Especially in the ultra-low temperature environment, cryogenic valves should have sufficient toughness to prevent brittle fracture, and at the same time require a stable material structure to ensure that there will be no dimensional changes due to phase changes during use, which will eventually lead to valve seal failure. Aus...
