Description

Technical Field

[0001] The present application relates to the technical field of pipeline detection devices, and in particular to a pressure pipeline leakage detection device. Background Art

[0002] In the process of transporting gas or liquid media, pressure pipelines are needed as channels for the transported media. Since pressure pipelines are under certain pressure conditions for a long time, in order to ensure the safe use of pressure pipelines, detectors are needed to detect leaks in pressure pipelines after production or during installation to avoid putting pressure pipelines with leaks into operation.

[0003] The document with prior art publication number CN217179847U provides a detection device for conveniently locating leaks in pressure pipelines. The device is fixed to the pipeline by two semicircular clamp frames. When a leak occurs in the pipeline, the gas at the leak will blow up the airbag on the arc frame, making it easier for people to observe the location of the leak through the inflated airbag.

[0004] Although the device has many beneficial effects, the following problems still exist: the device requires humans to spontaneously discover the leak location, and manual detection is prone to visual fatigue, which leads to incomplete observation and missing the leak location, making it inconvenient to locate and detect the leak in the pressure pipeline. In order to reasonably improve this problem, the present application proposes a pressure pipeline leak detection device. Utility Model Content

[0005] The purpose of this application is to provide a pressure pipeline leakage detection device in order to effectively and reasonably improve the problems presented in the above-mentioned background technology.

[0009] A monitoring device is electrically connected to the two tension sensors.

[0010] Furthermore, plug posts are distributed on the circumference of the two extrusion rings, and the plug posts penetrate the tubular rubber sleeve.

[0011] Furthermore, the plug post has a vertical section and a horizontal section, the vertical section is connected to the extrusion ring, the horizontal section is connected to the end of the vertical section, and the end of the horizontal section extends in a direction away from the tubular rubber sleeve.

[0012] Furthermore, when the tubular rubber sleeve is installed on the two extrusion rings, the tubular rubber sleeve coincides with the axis of the circular ring, and the inner diameter of the tubular rubber sleeve is larger than the inner diameter of the circular ring.

[0013] Furthermore, a sliding block is constructed on one of the circular rings, the sliding block is slidably matched with the mounting plate, and a positioning mechanism for fixing the sliding block is installed on the mounting plate.

[0014] Furthermore, the positioning mechanism comprises a rotating rod rotatably mounted on the mounting plate, the rotating rod threadably penetrates the sliding block, and a rotating handle is configured at the end of the rotating rod.

[0016] Furthermore, a guide rod is fixedly mounted on the mounting plate, the guide rod extends along the moving direction of the sliding block, and the guide rod slides through the circular ring.

[0017] The beneficial effects of the present application are as follows: by adopting the design of a tube-shaped rubber sleeve, when a pressure pipe with a leak passes through the circular ring, the leaked gas can apply force to the taut tube-shaped rubber sleeve, and thereby drive the two extrusion rings to squeeze the tension sensor, so that the inspection personnel can find out the leaking pressure pipe according to the fluctuating measurement values ​​of the monitoring device, and then the operator can quickly find the leak of the pressure pipe through the bulging tube-shaped rubber sleeve.

DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0024] like Figure 1-Figure 4 As shown, a pressure pipeline leakage detection device proposed in one embodiment of the present application includes:

[0025] A mounting plate 1, on which two circular rings 2 are symmetrically arranged, and a pressure test pipe for internal pressurization passes through the inner surfaces of the two circular rings 2. Annular grooves 3 are constructed on the opposite sides of the two circular rings 2, and tension sensors 4 are arranged in the annular grooves 3. The tension sensors 4 are located on the side where the annular grooves 3 are close to each other. Extrusion rings 5 ​​are arranged on the opposite sides of the two tension sensors 4, and the extrusion rings 5 ​​are slidably matched with the annular grooves 3. When the two extrusion rings 5 ​​slide relatively, the two tension sensors 4 between them can be squeezed. A tubular rubber sleeve 6 is arranged between the two circular rings 2, and the two ends of the tubular rubber sleeve 6 are respectively fixed to the two extrusion rings 5, and the tubular rubber sleeve 6 has toughness. The tubular rubber sleeve 6 is made of rubber and latex, and has strong tensile properties. When the two ends are installed on the two extrusion rings 5, it is in a taut state;

[0026] The monitoring device 7 is an existing structure, which includes a display screen for displaying the measured values ​​of the tension sensor 4. The monitoring device 7 is electrically connected to the two tension sensors 4. When the pressure test pipeline passes through the two rings 2, if the pressure test pipeline is intact and the tight tubular rubber sleeve 6 is not affected by external forces, the measured value of the tension sensor 4 will not change. If the pressure test pipeline has a leak, the pressurized gas in the pressure test pipeline is discharged from the leak. Because the internal pressure of the pressure test pipeline is greater than the atmospheric pressure, this causes the gas flow rate at the leak to be too fast. When the leak passes through the tubular rubber sleeve 6, the airflow can act on the tubular rubber sleeve 6, thereby applying force to the tight tubular rubber sleeve 6 to deform it. After the tubular rubber sleeve 6 is deformed, it will pull the two extrusion rings 5 ​​to move relative to each other, thereby forming an extrusion on the two tension sensors 4 between the two, so that the measured value of the monitoring device 7 changes. After the operator detects the change in value, he can stop moving the pressure test pipeline and quickly find the leak of the pressure pipeline based on the bulging tubular rubber sleeve 6.

[0027] The present application adopts the design of the tubular rubber sleeve 6. When a pressure pipe with a leak passes through the circular ring 2, the leaked gas can apply force to the taut tubular rubber sleeve 6, and thereby drive the two extrusion rings 5 ​​to squeeze the tension sensor 4, so that the inspection personnel can find out the leaking pressure pipe according to the fluctuating measurement value of the monitoring device 7. Then the operator can inflate the tubular rubber sleeve 6 to quickly find the leak of the pressure pipe. Compared with the prior art, the technical solution of the present application can quickly exclude intact pipes, thereby reducing the pipeline inspection time of the operator, so that the inspector is less likely to have visual fatigue, thereby reducing the situation where the leaking pressure pipe is missed due to incomplete observation of the inspector.

[0028] like Figure 1-Figure 4 As shown, in some embodiments, plug posts 8 are distributed on the circumferential sides of the two extrusion rings 5, and the plug posts 8 all penetrate the tubular rubber sleeve 6. If the tubular rubber sleeve 6 is in a stretched state for a long time, the rubber band will gradually lose its original elasticity, which will cause the detection effect of the tension sensor 4 to be easily affected. Such a design facilitates the installation and replacement of the tubular rubber sleeve 6 to improve the test effect of the tension sensor 4.

[0029] like Figure 4 As shown, in some embodiments, the column 8 has a vertical section 9 and a horizontal section 10, the vertical section 9 is connected to the extrusion ring 5, the horizontal section 10 is connected to the end of the vertical section 9, and the end of the horizontal section 10 extends in a direction away from the tubular rubber sleeve 6. With such a design, when installing the tubular rubber sleeve 6, the occurrence of the tubular rubber sleeve 6 slipping off the column 8 can be reduced, so as to facilitate the fixation of the tubular rubber sleeve 6.

[0030] like Figure 2 and Figure 3 As shown, in some embodiments, when the tubular rubber sleeve 6 is installed on the two extrusion rings 5, the tubular rubber sleeve 6 coincides with the axis of the circular ring 2, and the inner diameter of the tubular rubber sleeve 6 is larger than the inner diameter of the circular ring 2. Such a design makes it difficult for the pressure test pipe to come into contact with the tubular rubber sleeve 6 when passing through the circular ring 2, thereby reducing the situation where the tubular rubber sleeve 6 is scratched by the pressure test pipe.

[0031] like Figure 2 and Figure 3 As shown, in some embodiments, a sliding block 11 is constructed on one of the rings 2, such as Figure 2 As shown, the ring 2 is installed on the right side of the mounting plate 1, the ring 2 on the left side of the mounting plate 1 is fixedly connected to the mounting plate 1, the sliding block 11 is slidably matched with the mounting plate 1, and a positioning mechanism 12 for fixing the sliding block 11 is installed on the mounting plate 1. Such a design makes it possible to adjust the distance between the two rings 2 to facilitate the installation of the tubular rubber sleeve 6.

[0032] like Figure 2As shown, in some embodiments, the positioning mechanism 12 includes a rotating rod 13 rotatably mounted on the mounting plate 1, the rotating rod 13 is threaded through the sliding block 11, and a rotating handle 14 is configured at the end of the rotating rod 13. By rotating the rotating handle 14, the rotating rod 13 can drive the ring 2 to slide on the mounting plate 1 to adjust the distance between the two rings 2, and after the rotating rod 13 stops rotating, the sliding block 11 cannot slide on the rotating rod 13, thereby fixing the sliding block 11.

[0033] like Figure 2 As shown, in some embodiments, an anti-slip groove 15 is provided on the rotating handle 14, and a plurality of anti-slip grooves 15 are arranged in a circular array along the axis of the rotating handle 14. The anti-slip grooves 15 are designed to increase the surface roughness of the rotating handle 14 to reduce the slipping of the hand when the rotating handle 14 is turned.

[0034] like Figure 2 As shown, in some embodiments, the mounting plate 1 is fixedly mounted with a guide rod 16, the guide rod 16 extends along the moving direction of the sliding block 11, and the guide rod 16 slides through the ring 2, as shown in FIG. Figure 2 As shown, the penetrating ring 2 here is the ring on the right side of the mounting plate 1. By adopting the design of the guide rod 16, the ring 2 is not easy to shake when moving, which facilitates the horizontal sliding of the ring 2.

[0035] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present application. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
