Problems solved by technology
The gas storage tank currently used is composed of a left end cover, a cylinder body and a right end cover, but when the cylinder body and the cylinder body are connected, they are connected by welding. Since the ports are all plane ports when connecting, the plane port and the plane port are aligned. Welding, easy to cause incomplete welding, poor sealing performance, easy to cause air leakage and other phenomena
In addition, the air receiver used in the existing rail vehicle braking system is generally a single-chamber air cylinder made of carbon steel. After assembly, the overall weight is heavy, and the inner and outer surfaces need to be treated with anti-corrosion. The structure is not compact enough, and disassembly is complicated. , It is not convenient for post-maintenance

The invention discloses a double-cavity gas storage device used for a novel high-speed train brake system. The double-cavity gas storage device comprises a first barrel, a first end plate, a second barrel and a second end plate. Transverse weld joints are arranged on the first barrel and the second barrel. A longitudinal weld joint is arranged in the butt joint position of the first barrel and thesecond barrel. Air inflow holes and air outflow holes are formed in the first barrel and the second barrel. A preparation method includes the following steps that I, the first barrel is placed on a welding device, transverse joint welding is conducted, and the corresponding transverse weld joint is formed; II, the second barrel is placed on the welding device 1, transverse joint welding is conducted, and the corresponding transverse weld joint is formed; III, longitudinal joint welding is conducted on the first barrel and the second barrel, so that the longitudinal weld joint is formed, and the first barrel and the second barrel form an integrated structure; and IV, the welded first barrel and the welded second barrel are placed on a cutting fixing device, and the air inflow holes and theair outflow holes are cut.
Description
technical field [0001] The invention relates to a novel double-chamber air storage device for a high-speed rail braking system and a preparation method thereof. Background technique [0002] As a gas pressure device in the high-speed rail braking system, the gas storage is used to store the gas compressed by the air compressor for the braking system. The air receiver has four functions of energy storage, filtration, elegance and cooling. The gas storage tank currently used is composed of a left end cover, a cylinder body and a right end cover, but when the cylinder body and the cylinder body are connected, they are connected by welding. Since the ports are all plane ports when connecting, the plane port and the plane port are aligned. Welding, it is easy to cause incomplete welding, poor sealing performance, and easy to cause air leakage. In addition, the air receiver used in the existing rail vehicle braking system is generally a single-chamber air cylinder made of carbon...
