Abstract

The invention discloses a multifunctional air tightness detection device. A hose is used for connecting an air source through an air inlet, workpieces to be detected are placed in a sealing cavity, then a sealing cavity to be detected is connected with an air outlet through a three-way air pipe, the external air source is turned on for air intake, gas flows into the sealing cavity to be detected through a one-way valve, the pressure intensity of gas inside the sealing cavity can be monitored through a gas pressure gauge, when the pressure intensity meets testing requirement, a switch of the external air source is turned off, right now, the sealing cavity to be detected and the gas pressure gauge form an independent loop, the sealing conditions of the workpieces inside the sealing cavity can be tested through the data change condition of the gas pressure gauge, and the detection of air tightness can be carried out on a plurality of workpieces by using the equipment, so that the testingtime is shortened, the manpower is saved, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of airtightness testing equipment, in particular to a multifunctional airtightness testing device. Background technique [0002] Sealed workpieces need to be tested before leaving the factory. The existing detection method is: put the workpiece to be tested into the sealed cavity, and fill the cavity with inert gas. If the workpiece leaks, it will inevitably lead to air pressure in the sealed cavity. change. The testing device in the prior art can only complete the detection of a single workpiece for each operation. When a large number of workpieces need to be tested, it has the disadvantages of low testing efficiency and high labor intensity. Contents of the invention [0003] In order to solve the technical problems of low test efficiency and high labor intensity of workers in the prior art, the technical solution of the present invention is as follows: [0004] A multifunctional airtightness detection...
