[0028] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0029] Embodiment 1, as Figures 1 to 4As shown, a device for detecting the sealing performance of a gas pipeline comprises a first rectangular base 1 and a second rectangular base 2 which are arranged parallel to each other; the second rectangular base 2 is fixedly connected to the upper surface of the first rectangular base 1; a spacing gap is provided between the first rectangular base 1 and the second rectangular base 2; an air compressor 3 is provided on the upper surface of the second rectangular base 2, the exhaust port of the air compressor 3 is connected to the first end of a four-way joint 4 through a first manual valve 5, the second end of the four-way joint 4 is connected to a pressure gauge 7, the third end of the four-way joint 4 is connected to one end of a gas connecting hose 8; the fourth end of the four-way joint 4 is connected to one end of an exhaust pipe through a second manual valve 6, and the other end of the exhaust pipe extends into the spacing gap.

[0030] In this embodiment, the operator first finds the gas pipeline to be tested for sealing, connects the free end of the gas pipeline to be tested to the free end of the gas connection hose 8, and closes the valve closest to the other end of the gas pipeline to be tested. At this time, the gas pipeline and the valve connected to it are taken as a whole, and the sealing can be tested. Further, close the second manual valve 6, open the first manual valve 5, and open the air compressor 3 to inject high-pressure air into the gas pipeline to be tested. At this time, observe the barometer 7. When the set air pressure value is reached in the gas pipeline to be tested, close the first manual valve 5, and further close the air compressor 3. At this time, the gas pipeline to be tested is in a sealed high-pressure state. Continue to observe the barometer 7. If there is a problem with the sealing of the wall of the gas pipeline to be tested or the connection with the upper valve, the value of the barometer 7 cannot be maintained and will drop due to gas leakage. At this time, the operator can judge that the sealing of this section of the gas pipeline to be tested does not meet the requirements, and there is a problem with the sealing of the wall of the gas pipeline or the connection with the upper valve, and it is necessary to check the sealing leakage point. When the inspection is completed, the operator opens the second manual valve 6 to discharge the high-pressure gas in the inspected gas pipeline, thereby completing the sealing inspection of this section of the gas pipeline.

[0031] This gas pipeline sealing detection device is very suitable for checking the sealing of natural gas pipelines laid in indoor areas, kitchen areas or other small areas.

[0032] Embodiment 2, as Figure 2 As shown, a free end of the gas connecting hose 8 is provided with a pipeline joint 81, and the pipeline joint 81 is used to connect the gas pipeline to be tested for sealing.

[0033] In this embodiment, the gas connection hose 8 is a flexible hose, which is convenient for connecting to the gas pipelines to be inspected in various setting postures.

[0034] In this embodiment, the pipeline joint 81 can be selected in different joint forms according to the characteristics of the gas pipeline to be detected, such as a gas pipeline quick joint.

[0035] In this embodiment, the control end of the air compressor 3 is connected to a compressor controller 31 , and the compressor controller 31 is used to control the start and stop of the air compressor 3 .

[0036] Embodiment three, as Figure 1 As shown, the compressor controller 31 is installed on a fixing base, and the fixing base is connected to the second rectangular base 2.

[0037] In this embodiment, a handle 9 is provided on the edge of the upper surface of the second rectangular base 2 .

[0038] In this embodiment, if Figure 1 As shown, a vertical baffle 10 is provided on the upper surface of the second rectangular base 2 , and the air compressor 3 and the four-way joint 4 are respectively arranged on both sides of the baffle 10 .

[0039] In this embodiment, if Figure 4 As shown, the exhaust pipe port arranged in the spacing gap is arranged facing the first rectangular base 1.

[0040] In this embodiment, the exhaust pipe port is arranged to face the first rectangular base 1 to prevent the exhaust high-pressure gas from causing possible harm to the user when the second manual valve 6 is opened after the detection is completed.

[0041] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
