Buffering pad for relieving bidirectional expansibility of high-pressure gas bottle

Abstract

The invention provides a buffering pad for relieving the bidirectional expansibility of a high-pressure gas bottle. The buffering pad is 5mm thick and is rectangular 6144-type silicon rubber; a plurality of circular holes are formed in the 6144-type silicon rubber; a contact area accounts for 20 percent of the total area of the silicon rubber. The buffering pads are respectively positioned between a first belting and the gas bottle, a second belting and the gas bottle and a base and the gas bottle; a supporting and fastening device comprises a lower bracket and an upper bracket; the lower bracket is positioned at the bottom of the gas bottle and is connected with a cylindrical end socket of the gas bottle through a screw; the upper bracket comprises the first belting, the second belting and the base; the first belting is connected with the second belting through a bolt; the base is fixed on the structural side plate of a space vehicle; the first belting, the second belting and the base form an annular component. The buffering pad disclosed by the invention enables the gas bottle to be expanded and buffered due to own deformation; therefore, during deformation, load which can damage the beltings cannot be applied to the beltings.

Description

technical field [0001] The invention belongs to the technical field of mechanical parts, and in particular relates to a buffer cushion for alleviating the bidirectional expansion force of a high-pressure gas cylinder. Background technique [0002] In order to fix the gas cylinder on the main structure on the spacecraft, it is often used to tighten the gas cylinder to a bracket installed on the main structure. Between the outer surface of the gas cylinder and the strap, and between the outer surface of the gas cylinder and the bracket, a pad made of felt or rubber pad is usually placed to avoid hard contact between the outer surface of the gas cylinder, the strap, and the bracket. contact and protect the surface of the part. [0003] This kind of felt or rubber pad has the following disadvantages: when the gas cylinder is greatly deformed due to the filling of high-pressure gas, especially when there is a large deformation in the axial and radial directions, the expansion fo...

Problems solved by technology

[0004] In order to solve the above problems, the present invention provides a buffer pad for alleviating the two-way expansion force of the high-pressure gas cylinder, which can make the gas cylinder deform freely when it is filled with high-pressure gas, and at the same time ensure that the strap has a certain fastening force on the gas cylinder. case, the tape will not be damaged by excessive expansion force
