[0028] Example 1
[0029] like Figures 1-4As shown, the pipe joint sealing tester includes a base 1, a mounting bracket 2 detachably and fixedly connected to the top of the base 1, and a left plug 3 and a right plug 4 mounted between the mounting brackets 2 and arranged opposite to each other. An angle adjustment mechanism 5 is provided between the left plug 3 and the mounting bracket 2 to adjust the angle of the left plug 3. A through hole is opened in the center of the right plug 4 and a one-way valve is installed in the through hole. Sealing rings 6 are fitted on both the left plug 3 and the right plug 4. A relatively independent water inlet 7a and air vent 7b are provided on the right side of the base 1. The water inlet 7a and air vent 7b are respectively connected to the one-way valve in the right plug 4 and are used for water tightness test and air tightness test of the pipe joint 14.
[0030] To ensure stable fixation of the tested pipe joint 14 and pipe 13, the pipe joint 14 sealing test machine also includes a support device 8 for supporting the pipe 13 and a fixing device 9 for fixing the pipe joint 14. The support device 8 includes a push plate 801 and a cylinder 802 for driving the push plate 801. The side of the push plate 801 that contacts the pipe 13 is a downwardly concave arc surface, thereby increasing the contact area between the push plate 801 and the pipe 13 and providing stable support for the pipe 13. The telescopic end of the cylinder 802 is fixedly connected to the push plate 801, and the height of the push plate 801 can be linearly adjusted under the action of the cylinder 802. The fixing device 9 includes an upper clamping plate 901 and a lower clamping plate 902 arranged opposite each other, a height adjustment mechanism for adjusting the height of the upper clamping plate 901 and the lower clamping plate 902, and a clamping mechanism fixedly installed on the upper clamping plate 901 at the end away from the lower clamping plate 902. The height adjustment mechanism includes two first screws 903 mounted between the top and bottom of the mounting frame 2, an upper mounting plate 904 and a lower mounting plate 905 passing through the first screws 903, and mounting plates 906 for fixing the upper mounting plate 904 and the lower mounting plate 905. The upper clamping plate 901 and the lower clamping plate 902 are fixedly connected to the upper mounting plate 904 and the lower mounting plate 905 respectively. The mounting plates 906 are threadedly connected to the first screws 903. The mounting plates 906 are arranged in pairs, with a set of mounting plates 906 installed at the left and right ends of the upper mounting plate 904 and the lower mounting plate 905 respectively. The mounting plates are fixed by clamping the upper and lower ends of the mounting plates. When the height of the mounting plate needs to be adjusted, the upper clamping plate 901 and the lower clamping plate 905 are indirectly adjusted. When adjusting the height of plate 902, simply remove the bolts threaded onto a set of mounting plates 906 and move the mounting plates 906 up and down along the first screw 903. The clamping mechanism consists of two second screws 907 threaded onto the upper mounting plate 904. The ends of the second screws 907 are rotatably connected to the upper clamping plate 901, specifically by installing bearings between the upper clamping plate 901 and the second screws 907. A handle for easy rotation is also welded and fixed to the top of the second screws 907. After determining the height distance between the upper mounting plate 904 and the lower mounting plate 905, the upper clamping plate 901 is moved down by rotating the second screws 907, thereby cooperating with the lower clamping plate 902 to clamp and fix the pipe joint 14 between the two pipes 13.
[0031] Both the left plug 3 and the right plug 4 use inflatable sealing rings 6. Specifically, the left plug 3 is hollow inside. A circumferential groove is opened on the outer surface of the left plug 3. The sealing ring 6 is embedded in the groove. An inflation head 601 is fixedly installed on the sealing ring 6. A pipe 13 is connected to the inflation head 601 and the air source is connected. The pipe 13 is installed in the cavity inside the left plug 3. The air inlet end of the inflation head 601 is pre-fixed on the left plug 3. A threaded vent hole is opened on the sealing ring 6. The vent hole is threadedly fixedly connected to the air outlet end of the inflation head 601.
[0032] A slide bar 10 is installed between the mounting brackets 2. A slide seat 11 is slidably connected to the slide bar 10. A handle is threaded onto the slide seat 11. A chain link 12 is welded to the bottom of the handle. The end of the chain link 12 away from the handle is fixedly connected to the left plug 3. The slide seat 11 can move laterally along the slide bar 10 to adjust its position and is locked in place by screws installed on the slide seat 11. The chain link 12 further stabilizes the left plug 3 by pulling it, and also prevents the left plug 3 from falling to the ground and causing injury to workers.
[0033] A convex rail 101 is fixedly installed on the top of the base 1, and a socket 201 that plugs into the convex rail 101 is fixedly installed on the bottom of the mounting bracket 2. The bottom of the socket 201 has a groove for plugging into the convex rail 101. After the socket 201 is plugged into the groove, the mounting bracket 501 is locked onto the base 1 with screws. This detachable fixed connection method allows the fixed position of the mounting bracket 2 on the base 1 to be adjusted, thereby accommodating the fixing of pipes 13 of different lengths.
[0034] The angle adjustment mechanism 5 includes a mounting base 501 screwed to the mounting bracket 2, a rotating rod 502 threaded onto the mounting base 501 and the mounting bracket 2, and a handle fixedly mounted on the rotating rod 502 for easy rotation. A universal ball joint on the end of the rotating rod 502 away from the mounting bracket 2 is rotated, and the universal ball joint is fixedly connected to the left plug 3. With the cooperation of the universal ball joint, the tilt angle of the left plug 3 can be adjusted to accommodate the sealing of pipes 13 with different tilt angles.
[0035] The specific application process is as follows:
[0036] Before starting the test, activate the cylinder 802 on the right side to drive the push plate 801, raising the push plate 801. Then, place the pipe 13 assembled on the right side of the pipe connector 14 onto the push plate 801, ensuring that the outer surface of the pipe 13 is in close contact with the arc-shaped surface at the top of the push plate 801. Next, assemble the right end of the pipe 13 onto the left side of the pipe connector 14 to initially fix the pipe 13. Then, place the pipe connector 14 onto the lower clamping plate 902 and assemble the pipe connector 14 onto the pipe 13 located on the right side of the pipe connector 14. Then, move the upper clamping plate 901 downward by rotating the second screw 907, using the upper clamping plate 901 and the lower clamping plate 902 to press the pipe connector 14 together, thus fixing the pipe connector 14. Finally, place the pipe 13 located on the left side of the pipe connector 14 onto the left push plate 801, and then assemble the pipe 13 onto the pipe connector 14. Then, the staff rotated the rotating rod 502 to bring the left plug 3 closer to the pipe 13. During this process, the tilt angle of the left plug 3 was adjusted with the help of the universal ball until the left plug 3 was inserted into the pipe 13 and fixed. Finally, air was vented into the sealing ring 6 so that the sealing ring 6 would expand and tighten the inner wall of the pipe 13, creating a relatively sealed test environment inside the pipe 13.
[0037] During the test, water can be introduced into the water inlet 7a located on the right side of the base 1 to conduct a water tightness test, or air can be introduced into the air vent 7b to conduct an air tightness test.
[0038] Example 2
[0039] The difference between this embodiment and Embodiment 1 is that the left plug 3 and the angle adjustment mechanism 5, as well as the right plug 4 and the mounting bracket 2, are all connected in a detachable manner. For pipes 13 with large diameter differences, the left plug 3 and the right plug 4, which are more suitable for the pipe diameter, can be directly replaced.

Commonly known structures and characteristics in the solutions are not described in detail here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the structure of this utility model, and these should also be considered within the scope of protection of this utility model.
