Abstract

The invention discloses a sealing performance detecting device of a cylindrical part. The sealing performance detecting device comprises an upper end cover and a lower end cover which are mounted at two ends of a sleeve and is characterized in that an annular groove is formed at a position, contacting with the sleeve, of each of the upper end cover and the lower end cover, an upper sealing ring and a lower sealing ring are respectively arranged in the grooves, a plurality of screws are evenly distributed outside the sleeve, and two-ends of the screws are respectively fastened to the upper end cover and the lower end cover through butterfly nuts; an air faucet is arranged at the center of the upper end cover. The sealing performance detecting device has the advantages that the problem that the sealing performance of sequence sleeves is hard to detect by a conventional method is solved effectively, detection efficiency is increased, and measuring errors are reduced.

Description

technical field [0001] The invention belongs to a leak detection device, in particular to a leak detection device for cylindrical parts. Background technique [0002] Cylindrical parts are one of the main components of some mechanical equipment. According to the design requirements, the sealing performance of cylindrical parts is better. In order to test the tightness of the cylinder parts, a leak detector is generally used. During the leak detection process, the sleeve must be sealed with a device, and the air nozzle is left to connect with the leak detector hose. Especially in the process of inter-sequence testing, the sleeve has not been installed with a flange, and it is difficult to meet the testing requirements with conventional testing tools. Therefore, it is necessary to design a leak detection tool in combination with a leak detection instrument for leak detection. Contents of the invention [0003] The present invention is proposed in order to overcome the shor...
