Abstract

The invention relates to a low-temperature vacuum pipe connector comprising a liquid access pipe (4), an inner casing (7), a middle casing (6), and an outer casing (1). The head of the liquid access pipe (4) is connected with the bottom of a vacuum pipeline inner pipe (11) through a liquid access pipe connecting joint (9). The head of the outer casing (1) is connected with a vacuum pipeline outer pipe (12). A fiberglass insulating hoop (2) and a retainer ring (3) are connected to the bottom of the outer casing (1). The fiberglass insulating hoop (2) and the retainer ring (3) below the same are sequentially sleeved outside the liquid access pipe (4). The low-temperature vacuum pipe connector is effective in thermal insulation, the liquid access pipe is protected from external impact and distortion, cracks at a weld are avoided, and reliable quality is ensured; in addition, a connecting ring I, the middling casing, the inner casing and a connecting ring III are assembled and welded to form a thermal bridge component, a heat conducting path is added, heat conduction is effectively reduced, and delivery of low-temperature liquid can be insusceptible to external ambient temperature.

Description

technical field [0001] The invention relates to a low-temperature vacuum pipeline connection seat. Background technique [0002] Cryogenic vacuum pipes are used to store cryogenic liquids. During use, the liquid inlet and outlet pipes are easily subjected to external impact, which may cause distortions, which will cause cracks and fail to ensure the quality of the product; and under the influence of external temperature, lead to The low-temperature liquid in the vacuum pipeline is easy to evaporate, and the pressure rises, so there are certain hidden dangers. Contents of the invention [0003] The object of the present invention is to overcome the above-mentioned disadvantages and provide a low-temperature vacuum pipe connection seat with no cracks, more reliable quality and reduced heat conduction. [0004] The purpose of the present invention is achieved like this: [0005] A low-temperature vacuum pipeline connection seat, comprising a liquid inlet and outlet pipe, an...
