Special firm type stable explosion-proof piece for steel cylinder

Abstract

The invention relates to the technical field of steel cylinder accessories, in particular to a special firm type stable explosion-proof piece for a steel cylinder. According to the technical scheme, the explosion-proof piece comprises a spherical explosion-proof piece body structure, wherein the lower end of the explosion-proof piece body structure is provided with an integrally-formed cylindrical press-fit assembly fastening connecting column; and the lower end of the explosion-proof piece body structure is provided with an explosion-proof spherical safety groove. The explosion-proof piece is characterized in that the explosion-proof spherical safety groove completely penetrates through the lower end face of the press-fit assembly fastening connecting column; the inner side face of the explosion-proof spherical safety groove is parallel to the spherical face of the outer side of the explosion-proof piece body structure; and a first arc-shaped safety explosion-proof groove is formed in the position, close to the lower end, of the inner side of the explosion-proof spherical safety groove. The explosion-proof piece has the advantages that the structural design of the double safety explosion-proof grooves is adopted, so that the overall explosion-proof safety is improved, the connection stability during press-fit is better, and it is ensured that the connection firmness of the explosion-proof piece in the using process is more reliable.

Description

technical field [0001] The invention relates to the technical field of steel cylinder accessories, in particular to a special stable and stable explosion-proof disk for steel cylinders. Background technique [0002] Steel cylinders are steel cylinders used to store high-pressure oxygen, gas, liquefied petroleum gas, etc. The safety of steel cylinders during use has always been an important issue worthy of attention. The general structure of steel cylinders only has inlet and outlet safety valves, and the safety protection performance during use is relatively simple, whether it is during transportation or during use. It is more prone to safety accidents such as explosions. Contents of the invention [0003] The purpose of the present invention is to provide a special firm steel cylinder stable explosion-proof plate, which is used in conjunction with the main structure of the steel cylinder, and is usually installed at the upper end of the steel cylinder structure. It is s...
