In order to realize the purpose of this utility model, intend using following technology:
A kind of container leakage detection apparatus, it is characterised in that including source of the gas pipeline and signal piping, the source of the gas pipeline include by Pressure line connection air source inlet joint and source of the gas pressure gauge, the signal piping entrance be connected into the air source inlet joint and In the source of the gas pipeline between the bleed pressure table, the signal piping is sequentially provided with intake valve, pressure gauge from front to back With the fast interface of container.
Further, it is connected with pressure relief pipeline at the signal piping between the intake valve and the pressure gauge.
Further, relief valve is provided with the pressure relief pipeline.
Further, it is connected with source of the gas filter after the air source inlet joint.
Further, the pressure gauge selects high-precision pressure tester.
The beneficial effects of the utility model are:
Source of the gas, signal piping and pressure relief pipeline are integrated in set of device by the utility model, pass through the fast interface of container The high-speed communication with container to be checked is realized, is conducive to simplifying leak detection operation, ensures the sealing of leak detection system, so as to improve leak detection Efficiency and accuracy of detection.
Brief description of the drawings
Fig. 1 shows the structure principle chart of existing leakage detection apparatus.
Fig. 2 shows the utility model structure principle chart.
Fig. 3 shows structural representation of the present utility model in embodiment.
Embodiment
As shown in Fig. 2 a kind of container leakage detection apparatus, including source of the gas pipeline 1 and signal piping 2.The source of the gas pipeline 1 is used for Compressed air is provided for container 4 to be checked.The signal piping 2 is used for the pressure feelings for monitoring the compressed air of container to be checked 4 Condition, is hunted leak.
The source of the gas pipeline 1 includes the air source inlet joint 11 and source of the gas pressure gauge 12 connected by pressure line.The gas Source inlet joint 11 is supplied for connecting source of the gas.The bleed pressure table 12 is used to detect whether the pressure of supply source of the gas accords with Leak detection is closed to require.
The entrance of signal piping 2 is connected into the gas between the air source inlet joint 11 and the bleed pressure table 12 In source capsule road 1, the signal piping 2 is sequentially provided with intake valve 21, pressure gauge 22 and the fast interface 23 of container from front to back.It is described The fast interface 23 of container is used for signal piping 2 described in high-speed communication and the container to be checked 4.The intake valve 21 is used to control gas Source enters the container 4 to be checked by the signal piping 2.The detection pipe between the intake valve 21 and the pressure gauge 22 Pressure relief pipeline 3 is connected with road 2.Relief valve 31 is provided with the pressure relief pipeline 3.By regulating and controlling the intake valve 21 and the pressure release The folding of valve 31, you can use the air source inlet needed for the existing leak detection process of the fast replacement of interface 23 of the container, detection gas circuit Entrance and release air-path interface, are conducive to simplifying leak detection operation, improve leak detection efficiency, improve the sealing of leak detection system, improve Accuracy of detection.
Source of the gas filter 13 is connected with after the air source inlet joint 11.Be conducive to improving the clean level of source gas, keep away Exempt to pollute container to be checked.
The pressure gauge 22 selects high-precision pressure tester.Be conducive to improving precision of detecting leak gas.
The utility model embodiment is illustrated in conjunction with the embodiments:
As shown in figure 3, the air source inlet joint 11 is connected with source of the gas (compressed air), the bleed pressure table is read Whether 12 numerical value meets pressure requirements (3x105Pa).If it is not satisfied, being then pressurized to source of the gas or decompression processing.
By the fast interface 23 of the container by the utility model and reservoir to be checked.Close the relief valve 31, open The intake valve 21 is opened, source of the gas is filled with by the signal piping 2 in container to be checked, the numerical value at the pressure gauge 22 is Container inner pressure numerical value to be checked.
After the numerical value of the pressure gauge 22, which meets leak detection, to be required, the intake valve 21 is closed, container to be checked is protected Pressure.
During pressurize, the numerical value of pressure gauge 22 described in time recording, to judge whether container to be checked has leakage, if meet It is required that leak rate.
After the completion of pressurize, the relief valve 31 is opened, the compressed gas in container to be checked is discharged.
When dismantling the fast interface 23 of the container, the gas in container to be checked should be judged according to the numerical value of the pressure gauge 22 Whether it is completely expelled, it is ensured that installing/dismounting, completes container leak detection operation.
Intake valve 21 described in embodiment and the relief valve 31 select magnetic valve, and the pressure gauge 22 is pressed from high accuracy Force snesor.The intake valve 21 and the relief valve are regulated and controled according to the transmission data of the pressure gauge 22 by programmable controller 31 working condition, you can realize container automation leak detection operation.
