DETAILED DESCRIPTION

[0025] The technical solution of the present invention is further described in detail below in conjunction with specific implementation methods.

[0026] Example 1, see Figure 1 to Figure 7 As shown, a multifunctional valve dynamic detection device includes a box body 1, a placement rack is fixedly connected to the box body 1, a control panel 2 is connected to the box body 1, a pressurized air pump 3 is fixedly installed in the box body 1, and further includes:

[0027] A tube-releasing driving structure 4 connected to the box body 1, the tube-releasing driving structure 4 includes a delivery tube 5 fixedly connected to the pressurized air pump 3, the delivery tube 5 is slidably connected to the box body 1, the delivery tube 5 is connected to a winding portion 6 connected to the box body 1, the delivery tube 5 is connected to a clamping delivery portion 7, the clamping delivery portion 7 is connected to the box body 1, and a first control valve 8 is fixedly installed at one end of the delivery tube 5 away from the pressurized air pump 3;

[0028] A local closed pressurization structure 9 connected to the first control valve 8 includes a first closed portion 10 connected to the first control valve 8, the first closed portion 10 is connected to a second closed portion 12 via an air-conducting pressurization measuring portion 11, the first closed portion 10 and the second closed portion 12 have the same structure, and the first closed portion 10 and the second closed portion 12 are both connected to a moving drive portion 13.

[0029] When in use, the local closed pressurizing structure 9 is inserted into the pipeline, and the two groups of moving driving parts 13 respectively drive the first closed part 10 and the second closed part 12 to move in the pipeline and the valve. At the same time, the winding part 6 unwinds the delivery pipe 5, and the clamping delivery part 7 delivers the delivery pipe 5 to the pipeline. When it is necessary to perform a local closed test on the valve, the first control valve 8 is opened, and the pressurizing air pump 3 supplies high-pressure gas to the first closed part 10 through the delivery pipe 5. The air guide pressurizing measuring part 11 guides the high-pressure gas into the second closed part 12. As a result, the first closed part 10 and the second closed part 12 are expanded due to the high-pressure gas filling, so that the first closed part 10, the second closed part 12, and the pipeline form a closed space, and then the first closed part 10 and the second closed part 12 stop expanding, and the gas-guiding pressurization measuring part 11 inflates the first closed part 10, the second closed part 12, and the valve to form a closed space, and then the gas-guiding pressurization measuring part 11 stops inflating, and the gas-guiding pressurization measuring part 11 measures the air pressure change in the closed space. The present invention cooperates with the local closed pressurization structure 9, the tube release drive structure 4, and the pressurized air pump 3, so that the present invention can close a section of the pipeline or valve, and then pressurize the closed space and monitor the air pressure change, so as to facilitate finding the leakage location.

As the gas enters between the support shell 22 and the annular airbag 24, the annular airbag 24 swells and fits against the inner wall of the pipeline or the valve, during which the first air pressure sensing probe 25 measures the air pressure between the support shell 22 and the annular airbag 24.

[0033] In one case of this embodiment, an annular oblique side surface is provided on the annular airbag 24. Specifically, after the air pressure in the space between the first sealing portion 10, the second sealing portion 12, and the valve increases, the air pressure exerts pressure on the annular oblique side surface, thereby further increasing the air pressure between the annular airbag 24 and the support shell 22, and under the pressure of the air pressure, the tightness of the annular airbag 24 and the valve is improved.

When the present invention passes through the curved part of the pipeline, the strip airbag 27 is bent, so that the present invention adapts to the curved space of the pipeline, and then the second control valve 28 is closed, and the deflation head 32 performs the deflation operation. The space between the first closed part 10, the second closed part 12, the pipeline or the valve is inflated, and the second air pressure sensing probe 33 performs the air pressure measurement operation at the same time.
