Abstract

The invention provides a film flange which comprises a flange body, a vacuum groove, an annular film and an air inlet hole. The air inlet hole penetrates through the flange body, the vacuum groove is located in the end face of the flange body, the film and the flange body are welded and fixed, a chamfer with a certain angle is arranged on the joint of the film and the flange body, the film at the chamfer position is matched with the flange body, and the film covers the air inlet hole in a sealing mode. According to the film flange, the chamfer is arranged on the joint of the film and the flange body, the film at the chamfer position is matched with the flange body, after inflation, stress of the joint of the film and the flange body is small, and accordingly the film can be prevented from being torn from the flange body after inflation.

Description

technical field [0001] The invention relates to the field of mechanical engineering, in particular to a membrane flange. 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 simplified form as a...
