Abstract

The invention discloses an air-bag self-adapting automatic-erasing device and method for a low temperature filling system. The device comprises a mounting seat (8), the two sides of the mounting seat are provided with a rotating shaft (4) and a power device respectively, and the rotating shaft is fixedly provided with a bracket (3); an air bag (2) is laid on the rotating shaft and bracket, and the rotating shaft is provided with an air inlet (41) and first and second air outlets (42, 43); the air inlet is communicated with the first and second air outlets, and the first and second air outlets are communicated with the air bag and the outside respectively. The method includes the following steps that the rotating shaft extends into the inner cavity of the low temperature filling system, and the air is inlet from the air inlet to make the air bay expand; the rotating shaft is driven, plastic wires are used to wipe frost and ice down, and the air is compressed to blow the frost and ice down; the pressure of supplying air is adjusted until erasing is completed. The purpose is to provide the air-bag self-adapting automatic-erasing device and method for the low temperature filling system, and the device and the method have the advantages of being high in erasing efficiency, good in effect, strong in universality, high in automation degree, safe in use and the like.

Description

technical field [0001] The invention relates to the field of automatic low-temperature filling, in particular to an airbag self-adaptive automatic erasing device and method for a low-temperature filling system. Background technique [0002] In aerospace, aviation, LNG and other fields, cryogenic filling systems are widely used to fill cryogenic media (liquid hydrogen, liquid oxygen, liquid natural gas, etc.) During the low-temperature filling process, the temperature of the filling device, connectors, valves and other equipment in the filling system drops rapidly under the action of the low-temperature medium, and due to the moisture in the air, frosting and freezing occur on the outer wall. After the low-temperature filling is completed and the equipment falls off, the inner cavity of the equipment is exposed to the air, and frosting and freezing also occur rapidly. In order to ensure the safety of the low-temperature filling system and the normal execution of the secondar...
