Internal pressure detecting device for aerosol tank

Abstract

The invention relates to an internal pressure detecting device for an aerosol tank. The internal pressure detecting device for an aerosol tank comprises a base (1), a pressure detector, a fixed support (2), a fixed sheet rubber (3), an aerosol tank (4), a pinion and rack mechanism, a locating structure column (8), a telescopic locating piece (5) and a locating adjustment handle (10), wherein the pressure detector is arranged on the base (1), the aerosol tank (4) is fixed by the fixed support (2) and the locating structure column (8), the pressure detector is connected to the pinion and rack mechanism through the telescopic locating piece (5), the pinion and rack mechanism is connected to the locating adjustment handle (10) and is adjusted by the locating adjustment handle (10), so that the lengthwise position of the pressure detector is adjusted; and the telescopic locating piece (5) is used for adjusting the transverse position of the pressure detector relative to the aerosol tank (4). Compared with the prior art, the internal pressure detecting device has the advantages of effectively improving the testing process, optimizing testing data and the like.

Description

technical field [0001] The invention relates to a device for inspecting the internal pressure of an aerosol can, in particular to a device for detecting the internal pressure of aerosol cans of different sizes by adopting horizontal and vertical double positioning. Background technique [0002] In order to avoid disasters or secondary disasters that may occur or be caused by different types of dangerous goods during the transportation process, before the goods are transported, it is necessary to conduct a comprehensive investigation of the dangers of the transported goods. According to the United Nations "Recommendations on the Transport of Dangerous Goods According to the Manual of Tests and Standards "ST / SG / AC.10 / 11 / Rev.5, flammable aerosols need to be fully evaluated for their flammability hazards when they are shipped in order to make appropriate classifications. [0003] Aerosol products are mainly classified into: spray aerosol products and foam aerosol products. [0...

AI Technical Summary

Problems solved by technology

[0006] 1. Using manual extrusion, the force exerted by different personnel on the aerosol tank is very different, which directly affects the final test data;

[0007] 2. The aerosol tank has no fixing device, and the different postures adopted by different personnel directly affect the final test data;

[0008] 3. During the pressure release process of the aerosol, it is difficult for the inspectors to ensure that the same and large force is continuously applied, and repeated operations are prone to fatigue;

[0009] 4. During the pressure release process, the aerosol often carries different types of droplets and particles. After repeated tests, the pressure gauge will be polluted and the test data will be affected.
