Problems solved by technology

Existing pressure testers for aerosol cans all use pressure liquid for testing, and the pipeline connection is relatively complicated, which is prone to leakage of the test liquid, and when changing the test of the tank body and valve cover, it is necessary to simultaneously test the valve of the tank body and the valve cover. The control valve of the bonnet testing system is manually operated at the same time, and the test conversion can only be realized once it is opened and closed. The operation is extremely inconvenient and the degree of automation is low, which affects the test efficiency and test accuracy.

Abstract

The invention relates to a high-precision aerosol can pressure resistance tester consisting of a control box, an aerosol can body testing head, a valve cap testing head and a testing frame. The aerosol can body testing head and the valve cap testing head are fixedly arranged on the testing frame and are respectively connected with the water outlet and the gas outlet of the control box through an external liquid pipe and an external gas pipe; and a valve gap testing channel and an aerosol can body testing channel are arranged in the control box. The high-precision aerosol can pressure resistance tester has scientific and reasonable design, compact structure, good sealing performance and high precision, is convenient to operate and is highly innovative; the aerosol can body pressure resistance testing and the aerosol can cover pressure resistance testing can be easily switched through a control switch; and the pressure resistance testing process is safe.

Description

technical field [0001] The invention belongs to the field of packaging testing instruments, in particular to a high-precision aerosol can pressure tester. Background technique [0002] Aerosol cans are widely used packaging cans. Since their contents will generate a certain pressure during use, the pressure resistance of aerosol cans is one of the important indicators to ensure the safety of packaging. The pressure test of an aerosol can is usually completed on a pressure tester. The existing aerosol can pressure tester is mainly composed of a control box, a test stand, a tank body test head, and a valve cover test head. The tank test head and the valve cover test head are fixed on the test frame, the tank body of the aerosol can is clamped on the lower part of the tank test head, and the valve cover part of the aerosol can is clamped on the upper part of the valve cover test head. The tank body test head and the valve cover test head are connected with the pressure liquid ...
