[0001] The utility model relates to the technical field of compensators, in particular to a pressure plugging device for a directly buried compensator. Background Art

[0002] In the use of direct-buried compensators, leakage problems are prone to occur during long-term use due to factors such as environmental corrosion and pressure changes.

[0003] A pressure plugging device for a directly buried compensator currently in use has a connection between an upper clamp and a lower clamp that mostly needs to be fixed with professional tools, and the installation space of the directly buried compensator is relatively small, so it is easy to cause trouble to the installers during installation and adjustment, thereby reducing the installation efficiency of the installers and being unfavorable for the use of the device. At the same time, the sealing material between the upper clamp and the lower clamp in the device is prone to aging and deformation after long-term use, which reduces the sealing effect and reduces the reliability of the device.

The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0028] For examples, see Figure 1-6 , the utility model provides a technical solution:

[0029] A pressure plugging device for a direct-buried compensator comprises a compensator body 1, flanges 2 are provided at the left and right ends of the compensator body 1, an upper clamping seat 3 and a lower clamping seat 4 are respectively provided on the outer side of the compensator body 1, an upper support plate 301 is fixedly installed at the front and rear ends of the upper clamping seat 3, a mounting hole 302 and a limiting hole 303 are respectively opened on the top surface of the upper support plate 301, a sealing groove 304 and a No. 1 sealing rubber strip 305 are respectively provided on the bottom surface of the upper clamping seat 3, a mounting groove 401 and a No. 2 sealing rubber strip 402 are respectively provided on the top of the lower clamping seat 4, a sealing spring 403 and a sealing block 404 are respectively provided inside the mounting groove 401, a lower support plate 405 is fixedly provided at the front and rear ends of the lower clamping seat 4, a mounting column 406 is fixedly installed on the top of the lower support plate 405, a limiting block 407 is provided on the top of the limiting block 407, a limiting column 408 is penetrated by the top of the limiting block 407, and a compression spring 409 is sleeved on the outer side of the limiting column 408;

[0030] It should be noted that the outer surface of the flange 2 is provided with bolt holes;

[0031] Specifically, the vertical cross-section of the upper clamping seat 3 and the lower clamping seat 4 is a semicircular structure, the No. 1 sealing rubber strip 305 is embedded in the left and right ends of the bottom of the upper clamping seat 3, and the No. 2 sealing rubber strip 402 is embedded in the left and right ends of the top of the lower clamping seat 4, and the facing side surfaces of the No. 1 sealing rubber strip 305 and the No. 2 sealing rubber strip 402 are in contact with the outer surface of the compensator body 1, the bottom end of the sealing spring 403 is fixed to the bottom inner wall of the mounting groove 401, and its top end is fixed to the bottom of the sealing block 404, and the outer surface of the sealing block 404 is in sealing contact with the inner walls of the mounting groove 401 and the sealing groove 304 respectively, and the sealing block 404 is made of polytetrafluoroethylene material;

[0032] In this embodiment, the contact between the No. 1 sealing rubber strip 305 and the No. 2 sealing rubber strip 402 and the outer side of the compensator body 1 can ensure the sealed contact between the upper clamp seat 3, the lower clamp seat 4 and the compensator body 1. The support of the sealing spring 403 on the sealing block 404 forms a sealed fitting contact between the sealing block 404 and the mounting groove 401 and the sealing groove 304, thereby ensuring the sealing performance between the upper clamp seat 3, the lower clamp seat 4 and the compensator body 1, and facilitating subsequent leak plugging operations.

[0033] Specifically, the outer surface of the mounting post 406 contacts the inner wall of the mounting hole 302, and its top surface is flush with the top surface of the upper support plate 301. The limiting block 407 rotates eccentrically with the top surface of the mounting post 406 via the eccentric member, and its bottom surface forms frictional contact with the top surface of the upper support plate 301. The bottom end of the compression spring 409 is fixedly connected to the top surface of the limiting block 407, and its top end is fixed to the outer top end of the limiting post 408. The bottom end of the limiting post 408 extends below the limiting block 407 and is in firm contact with the inner wall of the limiting hole 303.

[0034] In this embodiment, the installation column 406 is mainly used to contact the installation hole 302, which can position the upper clamp seat 3 and the lower clamp seat 4. Under the eccentric rotation of the limit block 407, the limit block 407 and the top surface of the upper clamp seat 3 form a friction rotation. At the same time, the compression spring 409 can apply a downward force to the limit column 408, thereby realizing a stable connection between the limit column 408 and the limit hole 303, thereby playing a role in quickly installing the upper clamp seat 3 and the lower clamp seat 4, providing convenience for the installer.

[0035] The working process of the utility model is as follows: when using a pressure plugging device for a direct-buried compensator, the upper clamp seat 3 and the lower clamp seat 4 are placed on the upper and lower sides of the compensator body 1 respectively, and the No. 1 sealing rubber strip 305 and the No. 2 sealing rubber strip 402 are tightly fitted with the outer surface of the compensator body 1 during the movement, and then the mounting column 406 of the lower clamp seat 4 is inserted into the mounting hole 302 of the upper support plate 301 to achieve the preliminary positioning between the upper clamp seat 3 and the lower clamp seat 4, and then the limit block 407 is eccentrically rotated so that it forms a fixed position with the upper support plate 301 through the eccentric action. Friction contact, at the same time, the compression spring 409 is stretched and generates an elastic force. Under the guidance of the elastic force, the bottom end of the limit column 408 extends into the limit hole 303, thereby completing the fixed installation between the upper clamp seat 3, the lower clamp seat 4 and the compensator body 1. At this time, the sealing block 404 contacts the sealing groove 304 and squeezes the sealing spring 403, and the squeezed sealing spring 403 pushes the sealing block 404 to form a sealing fit with the sealing groove 304, so that the interior of the upper clamp seat 3 and the lower clamp seat 4 is effectively sealed, meeting the leakage plugging requirements of the compensator.

[0036] 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 variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
