[0022] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0023] As described in the background art, the structures are not effectively fixed to each other. Therefore, this embodiment provides a detachable combined sealing rubber pad, which fixes the combined sealing rubber pads to avoid displacement of the sealing rubber pads during use.

[0024] See also Figures 1 to 4 This embodiment proposes a detachable combined sealing rubber pad, including a first sealing ring 1 and a second sealing ring 2. An adjusting mechanism 3 arranged equidistantly is provided between the first sealing ring 1 and the second sealing ring 2. The adjusting mechanism 3 includes an adjusting sealing ring 301. By increasing or decreasing the number of the adjusting sealing rings 301, the distance value between the first sealing ring 1 and the second sealing ring 2 is adjusted, so that the thickness value of the sealing rubber pad can be adjusted conveniently, thereby improving the applicable scenarios of the sealing rubber pad.

[0025] A first limiting groove 302 adapted to the fixed gear rod 401 is provided in the middle of the adjusting sealing ring 301, a second limiting groove 303 adapted to the limiting slide bar 406 is provided in the middle of the adjusting sealing ring 301, and a second slideway 505 is provided on the surface of the adjusting sealing ring 301. The first limiting groove 302 facilitates the fixed gear rod 401 to pass through the adjusting sealing ring 301, and the second limiting groove 303 facilitates the limiting slide bar 406 to pass through the adjusting sealing ring 301. The first limiting groove 302 and the second limiting groove 303 fix the fixed gear rod 401 and the limiting slide bar 406 to fix the position of the adjusting sealing ring 301 to avoid displacement of the adjusting sealing ring 301 during use.

[0026] A fixing mechanism 4 for fixing the first sealing ring 1 is arranged inside the second sealing ring 2, and the fixing mechanism 4 includes a fixed gear rod 401, a fixed gear plate 402 and a limiting slide bar 406. The fixed gear rod 401 is fixed by the fixed gear plate 402, so that the first sealing ring 1 and the second sealing ring 2 are fixed together, and the combined sealing rubber pad is conveniently disassembled to improve the applicable scenarios of the combined sealing rubber pad. The position of each sealing rubber pad is limited by the limiting slide bar 406 to avoid the combined sealing rubber pad from loosening during use, thereby improving the stability of the combined sealing rubber pad in operation.

[0027] The top end of the fixed gear rod 401 is fixedly connected to the first sealing ring 1, and the bottom end of the fixed gear rod 401 is meshed with the fixed tooth plate 402.

The position of the fixed gear rod 401 is limited by the sliding groove 404. When the pipeline is running, the high pressure inside the pipeline squeezes the second sealing ring 2, which will make the fixed gear rod 401 and the fixed tooth plate 402 mesh more closely, thereby avoiding the fixed gear rod 401 and the fixed tooth plate 402 from disengaging during use.

[0028] The interior of the second sealing ring 2 is fixedly connected with a fixing ring 403, and the fixing tooth plate 402 is fixedly connected to the fixing ring 403, the top of the limiting slide bar 406 is fixedly connected to the first sealing ring 1, the middle of the fixing ring 403 is fixedly connected with a fixing sleeve 405, and the bottom end of the limiting slide bar 406 passes through the second sealing ring 2 and is slidably connected to the fixing sleeve 405, the internal structure position of the second sealing ring 2 is fixed by the fixing ring 403, and the service life of the rubber pad is increased, the bottom end of the limiting slide bar 406 is fixed by the fixing sleeve 405, and the fixing effect of the combined rubber pad of the limiting slide bar 406 is improved.

[0029] A limiting mechanism 5 is arranged outside the first sealing ring 1, and the limiting mechanism 5 comprises a supporting metal shell 501, a first slideway 503 and a second slideway 505. The first slideway 503 and the second slideway 505 are used to limit the running position of the supporting metal shell 501, and it is convenient to know the internal structure position of the combined sealing rubber pad, and it is convenient to disassemble and install the combined sealing rubber pad.

The deformation directions of the first sealing ring 1, the second sealing ring 2 and the adjusting sealing ring 301 are limited by the supporting metal shell 501, so that the combined sealing rubber pad can only be deformed axially, thereby improving the sealing effect and service life of the device.

[0030] An annular groove 502 is formed on the surface of the first sealing ring 1 , and the top of the supporting metal shell 501 is engaged with the annular groove 502 . The position of the supporting metal shell 501 is fixed by the annular groove 502 , thereby improving the stability of the supporting metal shell 501 when in use.

[0031] The surfaces of the first sealing ring 1 and the second sealing ring 2 are both provided with a first slideway 503, the inner wall of the supporting metal shell 501 is fixedly connected with a slide rail 504, and the first slideway 503 and the second slideway 505 are both slidably connected to the slide rail 504, the first slideway 503 and the second slideway 505 are both located in the same position as the fixed gear rod 401, and the fixed gear rod 401 is used to facilitate identification of the internal structure position of the rubber pad, reduce the difficulty of disassembling and installing the combined rubber pad, and improve maintenance efficiency; the supporting metal shell 501 performs secondary fixation on the positions of the first sealing ring 1, the second sealing ring 2 and the adjustment sealing ring 301 through the slide rail 504 and the first slideway 503 and the second slideway 505, thereby improving the stability of the rubber pad operation.

[0032] A sealing mechanism 6 is arranged inside the first sealing ring 1, and the sealing mechanism 6 includes a docking sleeve 601. The docking sleeve 601 provides secondary sealing for the pipeline to improve the sealing effect of the rubber pad, and the adjusting sealing ring 301 is sleeved on the surface of the docking sleeve 601 to seal the gaps between the rubber pads, thereby improving the sealing performance of the device during operation.

[0033] The docking sleeve 601 is fixedly connected to the first sealing ring 1, and an inclined annular notch is provided at the bottom end of the docking sleeve 601. A first anti-slip protrusion 602 is fixedly connected to the surface of the docking sleeve 601. Through the annular notch at the bottom of the docking sleeve 601, the bottom end of the docking sleeve 601 is in close contact with the second sealing ring 2, thereby preventing the docking sleeve 601 from flipping over due to excessive fluid pressure in the pipeline and reducing the possibility of fluid leakage.

[0035] Working principle: First, pass the fixed gear rod 401 through the first limiting groove 302, and the limiting slide rod 406 through the second limiting groove 303, and fix the appropriate number of adjusting sealing rings 301 on the surface of the first sealing ring 1, and then align the second sealing ring 2 and the first sealing ring 1 to each other, so that the fixed gear rod 401 and the fixed gear plate 402 are meshed with each other, and the first sealing ring 1 and the second sealing ring 2 are fixed together, and then the supporting metal shell 501 is sleeved on the surface of the sealing rubber pad, and the supporting metal shell is aligned with the annular groove 502. 501 is fixed in the position. When disassembling, first squeeze the top of the first sealing ring 1 to disengage the supporting metal shell 501 from the annular groove 502, disassemble the supporting metal shell 501, and then press the position of the first slide 503 to disengage the fixed gear rod 401 from the fixed gear plate 402, and disassemble the second sealing ring 2. Through the above device, the sealing rubber pads of each combination are fixed to avoid the sealing rubber pads from shifting during use.
