Technical Field

[0001] The present application relates to the field of pipeline pressure measurement, and in particular to a pressure measuring device for a building water supply pipeline. Background Art

[0002] Pipeline pressure testing is a safety check performed on pipeline systems after construction is completed or during scheduled maintenance. This test applies liquid or gas pressure exceeding the normal operating pressure of the pipeline to verify material strength, weld quality, joint tightness, and the pressure resistance of the entire system. Pressure testing can identify potential leaks and ensure the safety and reliability of pipelines after they are put into operation.

[0003] Currently, when measuring the pressure of a water supply pipe, if the internal pressure is high, it is necessary to manually adjust the pressure measuring device to adjust the pressure inside the water supply pipe. When the internal pressure is adjusted to an appropriate level, it is also necessary to manually close the adjustment device. Therefore, in actual use, personnel are required to check frequently, which is more troublesome and not conducive to improving the overall use effect. Utility Model Content

[0011] By adopting the above technical solution, when the movable member or the movable plug moves, the movable plug will not be stuck inside the connecting tube.

[0012] Preferably, a first connecting hole is provided on the connecting member, a second connecting hole is provided on the movable member, and the first connecting hole and the second connecting hole are connected via a spring.

[0013] By adopting the above technical solution, when the movable plug moves to the upper part of the pressure relief groove, the pressure inside the U-shaped tube can be released through the pressure relief groove, and then the movable part is restored to its original position by the force of the spring.

[0014] Preferably, the spring is located outside the push-pull rod, and the U-shaped tube and the connecting tube are at the same height.

[0019] By adopting the above technical solution, the U-shaped tube and the connecting tube can be easily connected so that the two are fixedly connected.

[0020] In summary, this application includes at least one of the following beneficial technical effects:

[0021] 1. The movable plugs at both ends of the U-shaped tube of this application are at a lower pressure at one end, which will gradually move to the other end. When the internal pressure is higher, the movable plug at the other end can be pushed up. After the movable plug moves up, the pressure relief groove is gradually exposed. When the movable plug moves to the upper part of the pressure relief groove, the pressure inside the U-shaped tube can be released through the pressure relief groove. The spring force returns the movable part to its original position, maintaining the balance of the movable plugs at both ends of the movable part. Manual pressure relief is no longer required, which improves the overall practicality.

[0022] 2. The present application enters the interior of the connecting tube through a U-shaped tube. At this time, the internal pressure can be detected through the pressure detection tube. When the pressure inside the U-shaped tube is large, it will push the movable plug to move inside the connecting tube. At this time, the movable part will tilt and lift the movable plug at the other end. After the movable plug moves up, the pressure relief groove will gradually be exposed, making it easier to relieve pressure. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The following is combined with Figure 1 - Figure 4 This application is described in further detail.

[0029] The embodiment of the present application discloses a pressure measuring device for a building water supply pipeline, including a water supply pipeline 1, a connecting pipe 2 is installed on the water supply pipeline 1, and the water supply pipeline 1 is connected to a U-shaped tube 5 through the connecting pipe 2. After the pressure enters the U-shaped tube 5, when the internal pressure at both ends is unbalanced, the movable plug 7 at one end can be pushed to move, a first connecting seat 3 is installed on the connecting pipe 2, a second connecting seat 4 is installed at the bottom of the U-shaped tube 5, the first connecting seat 3 and the second connecting seat 4 are fixed by bolts, which facilitates the connection of the U-shaped tube 5 and the connecting pipe 2, and connecting cylinders 6 are installed at both ends of the U-shaped tube 5, and a pressure relief groove 22 is opened on the upper part of the connecting cylinder 6. When the movable plug 7 moves to the pressure relief groove 22 When the upper part of the U-shaped tube 5 is moved, the pressure inside the U-shaped tube 5 can be released through the pressure relief groove 22. A horizontal platform 14 is installed in the middle of the U-shaped tube 5, and a connecting piece 15 is installed on the horizontal platform 14. A connecting shaft 16 is installed on the connecting piece 15, and the connecting piece 15 is connected to the push-pull rod 13 through the connecting shaft 16. A movable shaft 12 is installed on the upper part of the push-pull rod 13, and the push-pull rod 13 is connected to the movable piece 10 through the movable shaft 12. The two ends of the movable piece 10 are movably connected with a movable plug 7. The movable plug 7 is located inside the connecting tube 6. When the movable plug 7 moves, it can keep moving along the inside of the connecting tube 6 to prevent the movable plug 7 from tilting during movement, which makes it difficult to move the movable plug 7.

[0030] A movable groove 11 is provided on the movable part 10. The width of the movable groove 11 is adapted to the diameter of the movable shaft 12. The movable shaft 12 is located inside the movable groove 11. Mounting shafts 9 are installed at both ends of the movable part 10. A protrusion 8 is installed on the upper part of the movable plug 7. The movable part 10 is movably connected to the protrusion 8 through the mounting shaft 9. When the movable part 10 or the movable plug 7 moves, the movable plug 7 will not be stuck inside the connecting tube 6.

[0031] A first connecting hole 18 is provided on the connecting member 15, and a second connecting hole 17 is provided on the movable member 10. The first connecting hole 18 and the second connecting hole 17 are connected by a spring 19. After the pressure relief groove 22 can release the pressure inside the U-shaped tube 5, the movable member 10 can be restored to its original position by the force of the spring 19.

[0032] The spring 19 is located on the outside of the push-pull rod 13, the U-shaped tube 5 and the connecting tube 6 are at the same height, and a pressure detection tube 20 is installed on the inside of the connecting tube 6. One end of the pressure detection tube 20 is connected to a pressure gauge 21, which enters the interior of the connecting tube 6 through the U-shaped tube 5. At this time, the internal pressure can be detected through the pressure detection tube 20.

[0033] The implementation principle of the present application is as follows: when in use, the pressure in the water supply pipe 1 will enter the interior of the U-shaped tube 5 through the connecting tube 2, and enter the interior of the connecting tube 6 through the U-shaped tube 5. At this time, the internal pressure can be detected by the pressure detection tube 20. When the pressure inside the U-shaped tube 5 is relatively high, the movable plug 7 will be pushed to move inside the connecting tube 6. At this time, the movable part 10 will be tilted. At this time, the spring 19 will gradually deform, and the movable plugs 7 at both ends of the U-shaped tube 5 are at a lower pressure and will gradually move to the other end. When the internal pressure is relatively high, the movable plug 7 at the other end can be lifted up. After the movable plug 7 moves up, the pressure relief groove 22 will gradually be exposed. When the movable plug 7 moves to the upper part of the pressure relief groove 22, the pressure inside the U-shaped tube 5 can be released through the pressure relief groove 22, and then the movable part 10 is restored to its original position by the force of the spring 19, so as to maintain the balance of the movable plugs 7 at both ends of the movable part 10.

[0034] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
