Description

Technical Field

[0002] A pressure vessel is a closed container that withstands pressure loads. Its main function is to store and transport high-pressure gases or liquids, or to provide a closed space for heat exchange and material reactions. It is widely used in petrochemical, pharmaceutical, metallurgical, aerospace, light industry and textile industries. Pressure testing is required during a comprehensive inspection to ensure that the pressure vessel meets the standards for continued use.

The utility model places the pressure vessel between the two clamping plates, and the two clamping plates automatically shrink under the influence of the springs. When the two clamping plates shrink to a certain extent, the two clamping plates clamp the pressure vessel under the influence of the springs, and the plug on the box cover is inserted into the socket in the fixing box, and then the screw is turned to hold the clamping plates against, so as to complete the fixing of the pressure vessel.

At the same time, dust is easily adhered to the surface of the pressure vessel, which is not convenient to clean. For this reason, we propose a fixing device for pressure vessel detection.
