Description

Technical Field

[0001] The utility model belongs to the field of air tightness detection devices, in particular to an air bag inflation detection device. Background Art

[0002] Pipeline plugging airbags are used for temporary plugging of pipelines. The plugging is to place the airbag into the pipeline, and then fill the airbag with nitrogen to inflate it to complete the plugging. In order to ensure that the airbag plays a stable plugging role, the airbag will be tested for air tightness in advance. Traditional air tightness testing usually uses an inflation tube with a pressure gauge. The inflation tube can connect the airbag and the air source. A valve is set on the inflation tube. After the airbag is inflated, the valve is closed to maintain pressure. If the pressure value decreases beyond the specified range, then the airbag has an air tightness problem, but this method of detection is not efficient. Utility Model Content

[0003] The purpose of the utility model is to provide a detection device which can detect multiple airbags at one time to improve the detection efficiency.

[0004] The technical solution adopted by the utility model is as follows:

[0005] An airbag inflation detection device comprises a support, a support pipe is arranged on the support, an air inlet is arranged on the support pipe, the support pipe comprises vertical pipes located on both sides and a horizontal pipe connected to the top of the two vertical pipes, the vertical pipe is connected to the horizontal pipe, a bracket is arranged on the support pipe, the bracket comprises multiple layers, a detection tube is arranged between the two vertical pipes, the detection tube is connected to the vertical pipe, the number of the detection tubes corresponds to the bracket, the bracket is located below the corresponding detection tubes, a plurality of detection components are arranged on the detection tubes at intervals, the detection components comprise a sub-inspection pipeline, an airbag connecting pipe and an instrument connecting pipe, the sub-inspection pipeline is connected to the detection pipe, a valve 1 is arranged on the sub-inspection pipeline, the airbag connecting pipe and the instrument connecting pipe are connected to the sub-inspection pipeline via a three-way pipe.

[0006] A further technical solution is that the bracket includes support rods located on both sides of the vertical pipe, and the support rods are fixed to the vertical pipe.

[0007] A further technical solution is that a gas tank is arranged on one side of the support, the gas outlet of the gas tank is connected to the gas inlet through an air pipe, and a second valve is arranged on the air pipe.

[0008] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0009] By arranging a supporting pipeline on the seat, the supporting pipeline includes a connected vertical pipe and a horizontal pipe, and the airbag can be placed on the bracket when in use. The bracket includes multiple layers and can be used to place multiple layers of airbags. The detection tube has multiple detection components, and each detection component corresponds to an airbag. The detection pipeline of the detection component is connected to the detection tube, and a valve is arranged on the detection pipeline. The airbag connecting pipe and the instrument connecting pipe are connected to the detection pipeline through a three-way pipe. The airbag connecting pipe is connected to the airbag, and the instrument connecting pipe is connected to the pressure gauge. The detection gas is ventilated into the supporting pipeline. After each airbag reaches a specified pressure value, all valves are closed. After being placed for a period of time, the changes of each pressure gauge are observed. If the pressure value drops by more than the specified value, it can be considered that the corresponding airbag has a leakage problem. In this way, a detection device that can detect multiple airbags at the same time to improve the detection efficiency can be realized, which can save time and effort compared with traditional methods.
