Abstract

The invention provides an inflation type corrugated pipe device which comprises a first flange, a vacuum groove, an air inlet hole and an annular film. The air inlet hole penetrates through the first flange, the vacuum groove is located in the end face of the first flange, the film and the first flange are welded and fixed, a chamfer with a certain angle is arranged at the joint of the first flange and the film, the film at the chamfer is matched with the first flange, the film covers the air inlet hole in a sealed mode, an inner corrugated pipe body and an outer corrugated pipe body are fixedly welded to the side, far away from the film, of the first flange, and second flanges are fixedly welded to one end of the inner corrugated pipe body and one end of the outer corrugated pipe body. According to the scheme, after inflation, stress at the joint of the film and the first flange is small, and the film can be prevented from being torn from the first flange after inflation.

Description

technical field [0001] The invention relates to the field of mechanical engineering, in particular to an inflatable bellows device. Background technique [0002] In high-energy accelerators, sealing flanges are required to connect the vacuum boxes. Most of the existing sealing flanges are KF and CF flanges, which are connected by bolts or quick-release chains at short distances. Vacuum tight. However, the above-mentioned sealing flange must be used for sealing at close range, and cannot be applied to high-radiation areas where people cannot approach. Contents of the invention [0003] A brief overview of the invention is given below in order to provide a basic understanding of some aspects of the invention. It should be understood that this summary is not an exhaustive overview of the invention. It is not intended to identify key or critical parts of the invention nor to delineate the scope of the invention. Its purpose is merely to present some concepts in a simplifie...
