Abstract

The invention discloses an air cylinder seal cap and belongs to the field of processing of air cylinders. The seal cap disclosed by the invention is provided with bosses distributed on a circumference with the apex of the cambered surface of the seal cap as the centre of a circle; each boss comprises a horizontal plane, a cambered transitional seal cap surface and a first transitional surface and a second transitional surface of the horizontal plane, and the apexes of the horizontal plane and cambered transitional seal cap surface of each boss are located on the same horizontal plane; the end, which is adjacent to the horizontal plane, of each first transitional surface is an inclined plane, and the end, which is adjacent to the cambered transitional seal cap surface, of each first transitional surface is a circular arc surface; the second transitional surfaces are cambered surfaces. According to the air cylinder seal cap design disclosed by the invention, the traditionally used standard tube holder is welded on a seal cap boss; as planar welding is adopted, the tube holder is small in deformation after being welded, and the horizontal size of the tube holder is better ensured, thus not only meeting the requirement on the direction of the tube holder, unifying the tube holder standard, facilitating the welding and saving the welding cost of the tube holder.

Description

technical field

[0001] The invention relates to the technical field of gas storage tank processing, and more specifically, relates to the design of the head of a gas storage tank for automobiles. Background technique

[0002] The air storage tank is a device for storing the compressed gas of the air compressor (air pump) in the automobile braking system. In the traditional technology, the vent tube of the air reservoir is connected by a hose, see figure 1 In (a) and (b), the direction of the tube base 1 is perpendicular to the tangent direction of the arc of the head 2. This connection method between the tube base 1 and the head 2 can facilitate the welding of the tube base 1 very well.

[0003] However, with the continuous development of science and technology, the requirements for the appearance and quality of the gas storage tank are getting higher and higher. More and more air pipes of gas storage tanks are connected by hard pipes, and the way of hard pipe connection r...
