Description

Technical Field

[0001] This utility model relates to the technical field of pipe joint sealing performance testing, specifically a pipe joint sealing performance testing device. Background Technology

[0002] When pipelines are used to transport media, it is often necessary to ensure the sealing of the pipelines, especially at the joints between adjacent pipelines, where leaks are very likely to occur. Therefore, it is necessary to use a pipeline joint sealing test device to test the sealing of the pipeline joints.

[0003] As disclosed in CN213842556U, a pipe joint airtightness testing device includes a first housing, a second housing, a pressure testing device, and a pressure gauge. The opening edge of the first housing covers the opening edge of the second housing, and the first and second housings are detachably connected. The first and second housings enclose each other to form a test chamber. The first and second housings hug the outer wall of the pipe so that the pipe joint is located inside the test chamber. The pressure testing device and the pressure gauge are both connected to the test chamber. If maintenance personnel find that the test chamber can maintain sufficient pressure for a sufficient time, it indicates that the pipe joint is well-sealed. If the pressure in the test chamber drops, it indicates that the pipe joint has insufficient sealing, and gas is leaking into the pipe, requiring maintenance.

[0004] However, the existing technology has problems such as complicated and cumbersome installation operations at the connection between the detection device and the pipeline, inconvenience in quickly docking and positioning the upper and lower boxes, and inconvenience in disassembling and maintaining the pressure gauge and pressure head used for detection. For example, the comparative patents listed above have this problem.

[0005] To address this issue, we propose a pipe joint sealing performance testing device. Utility Model Content

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] Please see Figures 1-8 The present invention provides the following technical solution.

[0036] Example 1: To address the problems of complex and cumbersome installation operations at the connection between the detection device and the pipeline in existing technologies, and the inconvenience of quick docking and positioning between the upper and lower housings, this example provides a pipeline interface sealing detection device comprising a lower housing 1, an upper housing 2, and an installation mechanism 4. The upper housing 2 and the lower housing 1 are respectively engaged and connected to the upper and lower ends of the pipeline connection. The installation mechanism 4 is symmetrically arranged at the front and rear ends of the lower housing 1, and includes an installation block 5, an installation plate 6, a movable plate 7, a movable rod 8, and a spring 9. The installation mechanism 4 drives the upper housing 2 to form a disassembly mechanism at the upper end of the lower housing 1. The upper housing 2 has mounting blocks 5 fixedly connected to both the front and rear sides of its lower end. These mounting blocks 5 are engaged with the upper end of an "L"-shaped mounting plate 6. The mounting plate 6 is fixedly connected to both the front and rear sides of the upper end of the lower housing 1. A movable plate 7 is provided on the outer side of the mounting plate 6. The upper end of the movable plate 7 is inserted into the mounting block 5, and the upper end of the movable plate 7 fits against the lower side of the mounting block 5. A movable rod 8 is fixedly connected to the lower end of the movable plate 7, and a spring 9 is sleeved on the outer surface of the movable rod 8. The movable rod 8 and the mounting plate 6 form a sliding structure, and the movable rod 8 drives the movable plate 7 to form an elastic structure on the outer side of the mounting plate 6. Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, firstly, the lower housing 1 is engaged at the lower end of the pipe connection, and then the upper housing 2 is engaged at the upper end of the pipe connection. The upper housing 2 drives the mounting block 5 to engage at the middle of the mounting plate 6, and the mounting block 5 contacts and presses the movable plate 7, causing the movable plate 7 to drive the movable rod 8 to slide between the movable rod 8 and the mounting plate 6. The movable rod 8 presses the spring 9, causing the spring 9 to undergo elastic deformation. When the upper housing 2 is fully engaged at the upper end of the pipe connection, the spring 9 returns to its elastic deformation, pushing the movable rod 8 to slide between the movable rod 8 and the mounting plate 6, so that the movable rod 8 drives the movable plate 7 to be sleeved on the outside of the mounting block 5. Thus, the lower housing 1 and the upper housing 2 can be fixed at the pipe connection very quickly and conveniently.

[0037] Example 2: To address the problems existing in the prior art, this example provides a pipe joint sealing performance testing device, comprising a first sealing gasket 3, a cover plate 10, a pressure gauge 11, a pressure testing head 12, and a second sealing gasket 13. The first sealing gasket 3 is fixedly connected to the outer edges of both the lower housing 1 and the upper housing 2, and is fitted snugly against the pipe. The cover plate 10 is engaged with the upper end of the upper housing 2, and the pressure gauge 11 is fixedly installed on the upper end of the cover plate 10. The pressure testing head 12 is located below the cover plate 10. The second sealing gasket 13 is fitted snugly between the cover plate 10 and the upper housing 2. Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the first sealing gasket 3 is fitted between the lower housing 1 and the upper housing 2, and the left and right ends of the first sealing gasket 3 are fitted with the pipe. At the same time, the cover plate 10 is fitted with the upper housing 2. The first sealing gasket 3 and the second sealing gasket 13 are used to improve the airtightness of the connection device during use. The pressure detection head 12 is inserted into the upper housing 2, and the pressure gauge 11 is set on the upper end of the cover plate 10. The sealing performance of the pipe connection is tested by the cover plate 10 and the pressure gauge 11. The cover plate 10 and the pressure gauge 11 are both existing mature technologies and will not be described in detail.

[0038] Example 3: To address the problem of inconvenience in disassembling and maintaining the pressure gauge 11 and pressure head 12 used for testing in the prior art, this example provides a pipe interface sealing testing device, comprising a support block 14, a fixing plate 15, and a fixing bolt 16. Fixing plates 15 for clamping and limiting are fitted to both the left and right sides of the upper end of the cover plate 10. Support blocks 14 are fixedly connected to both the left and right sides of the upper end of the upper housing 2. The upper end of the support block 14 is hinged to the fixing plate 15, and a fixing bolt 16 is provided in the middle of the fixing plate 15. The fixing bolt 16 is threadedly connected to both the fixing plate 15 and the support block 14. Figure 1 , Figure 7 and Figure 8 As shown, when the pressure gauge 11 and pressure head 12 need to be disassembled and maintained, the limiting position between the fixing plate 15 and the support block 14 can be loosened by rotating the fixing bolt 16. Then, the fixing plate 15 is flipped over, and the fixing plate 15 rotates with the support block 14. The fixing plate 15 is then separated from the cover plate 10, thereby loosening the clamping limit on the cover plate 10. Then, the cover plate 10 is pulled upward, and the cover plate 10 drives the pressure gauge 11 and pressure head 12 to be disassembled, making it convenient for maintenance.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
