Problems solved by technology

[0002] Existing gas crackers (crackers) are hereinafter referred to as crackers, such as: CN201611099345.2, CN201520283079.3, CN201510489513.8, CN201510556527.7. No matter which of the above methods is used for production, there will be weak points in the connection between the inflation head, the energy dissipation head and the expansion pipe, which will cause the cracker to crack first when the cracker expands, and the flying head will appear.
[0003] The existing cracker (cracker) still has many components, and the technical problems of complex processing and assembly processes for each component
[0004] For example, the patent document with the notification number CN205858345U discloses "plug, expansion tube, activator, liquid filling hole and lock valve, the plug is provided with an activator installation port, and the plug or expansion tube is provided with a liquid filling hole." "Although it saves a lot of parts and assembly steps compared with other crackers, there are still two processings at both ends of the expansion tube, that is, one end needs to be welded during assembly, and the other end needs to be threaded and sealed, or both ends are connected by welding. The welding master's technical level is extremely high. Less than 20% of the joints are welded with a constant thickness and no gaps. Thread processing, the two ends of the expansion tube after thread processing are weaker than the unprocessed tube body, s

Abstract

The invention discloses an anti-flying head supercritical oxygen gas cracker, which comprises an expansion tube and an inflatable ignition head. One end of the expansion tube is shrunk and sealed, and the other end is shrunk with an inflatable igniter; Fix the expansion tube, then rotate the expansion tube and heat the end of the expansion tube through the clamp, heat the end of the expansion tube to near or reach the plastic deformation, and after the front part of the shrinking mold touches the end of the expansion tube, the end of the expansion tube is from The shrinking mold moves from the front to the tail, and the shrinking mold extrudes and thickens the end of the expansion tube, and then uses a through-hole knife to make a through hole at the end of the expansion tube to fix the aperture; the other end is extruded and thickened, Through-hole fixed hole diameter, or sealing and thickening molding. The expansion tube is made into a pressure vessel by shrinking. The utility model has the advantages of simple structure, easy processing of structural components, low manufacturing cost, no flying head, no air leakage, safe transportation, no hidden danger of squib, and large expansion force.

Description
