[0024] The interior of the connecting tube 3 is fixedly plugged with equidistantly arranged fixing seats 7, and a threaded rod 8 is rotatably plugged into the interior of each fixing seat 7. A limiting ring 9 is fixedly sleeved on the outer circumference of the threaded rod 8. The outer circumference of the limiting ring 9 is rotatably connected to the interior of the fixing seat 7 to limit the threaded rod 8, prevent the threaded rod 8 from sliding and rising, and increase the stability of the movement of the threaded rod 8.

[0025] The outer circumference of the threaded rod 8 is threadedly connected to a positioning rod 10, and the outer circumference of the positioning rod 10 is fixedly connected to two limit plates 11. Two limit grooves 12 are provided inside the fixed seat 7. The outer surface of the limit plate 11 is slidably connected to the fixed seat 7 through the limit grooves 12, which restricts the positioning rod 10 to prevent the positioning rod 10 from rotating with the threaded rod 8, thereby prompting the positioning rod 10 to always maintain longitudinal lifting.

[0026] The outer circumferential surface of the pipe mouth 2 is provided with equidistantly arranged positioning grooves 14, and the outer circumferential surface of the positioning rod 10 is slidably plugged with the pipe mouth 2 through the positioning grooves 14. The connecting pipe 3 and the pipe mouth 2 are connected and positioned through the positioning grooves 14 and the positioning rod 10, which is convenient for installation and disassembly, and increases the stability of the connection, avoids loose connection, and affects the sealing effect of the connection. A sliding groove 15 is provided inside the connecting pipe 3, and the connecting pipe 3 is rotatably sleeved with a handwheel 16 through the sliding groove 15, and the outer circumferential surface of the connecting pipe 3 is fixedly sleeved with a shell 22.

[0027] See also Figure 4 and Figure 6 Two auxiliary rods 5 are fixedly connected to the inner side wall of the connecting pipe 3, and two auxiliary grooves 6 are provided inside the pipe mouth 2. The outer circumferential surface of the auxiliary rod 5 is slidably connected to the pipe mouth 2 through the auxiliary groove 6. The connecting pipe 3 and the pipe mouth 2 can be auxiliaryly connected through the auxiliary rod 5 and the auxiliary groove 6, which facilitates the connection between the connecting pipe 3 and the pipe mouth 2.

The gear 13 is meshed with the external gear ring 17, so that the worker can rotate the handwheel 16 to drive the gear 13 to rotate through the external gear ring 17, and then drive the positioning rod 10 to be retracted and positioned under the action of the threaded rod 8.

[0030] The implementation principle of a fracturing pump valve box pipe mouth connection sealing device in the embodiment of the present application is: when the pipe mouth 2 and the connecting pipe 3 need to be disassembled and maintained, the nut 21 is first removed to release the positioning restriction between the connecting pipe 3 and the pipe mouth 2 by the nut 21, and then the hand wheel 16 is turned to drive the outer gear ring 17 to rotate, and the outer gear ring 17 drives the threaded rod 8 to rotate through the gear 13, and the threaded rod 8 drives the positioning rod 10 to move from the inside of the positioning groove 14 to release the positioning connection between the connecting pipe 3 and the pipe mouth 2, and then the connecting pipe 3 can be removed, and when the connecting pipe 3 and the pipe mouth 2 need to be connected and positioned, the auxiliary rod 5 on the inner wall of the connecting pipe 3 is aligned with the auxiliary groove 6, and then the connecting pipe 3 is sleeved on the pipe mouth 2, and then the hand wheel 16 is rotated in the opposite direction to drive the positioning rod 10 to insert into the positioning groove 14, and finally the nut 21 is installed on the fixing rod 19, and the nut 21 is tightened.

[0031] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto.
