Description

Technical Field

[0001] The utility model relates to the technical field of spherical compensators, in particular to a highly wear-resistant spherical compensator. Background Art

[0002] The spherical compensator is a component used to solve the thermal expansion and contraction of the pipeline due to temperature changes. The spherical compensator uses the angular displacement of the sphere to absorb or compensate for the lateral displacement of the pipeline in one or more directions. A single unit can be used as a universal joint for the pipeline.

[0003] Since the spherical compensator needs to operate for a long time after being installed in the pipeline, the relative movement between the outer sleeve and the ball of the spherical compensator after long-term operation will cause wear of the sealing packing, which can easily affect the sealing effect of the spherical compensator; the spherical compensator generally achieves compensation through the angular displacement of the ball, but the compensation range of the spherical compensator is generally relatively fixed, which reduces the flexibility of the spherical compensator when used; in the process of connecting the spherical compensator to the pipeline, the user is usually required to manually align the screw holes first, and then use bolts to fix it, which is more cumbersome, thereby reducing the convenience of connecting the spherical compensator to the pipeline.

The surface of the wear-resistant sealing sleeve 202 fits tightly with the surface of the sphere 104, and the interior of the wear-resistant sealing sleeve 202 is filled with sealing filler 203. A filling component 201 is arranged on one side of the sealing filler 203. The filling component 201 consists of a threaded cover 2011, a threaded tube 2012, a sealing pressure column 2013 and an elastic column 2014. The surface of the outer sleeve 1 is fixed with a threaded tube 2012 along the circumferential direction. The threaded tube 2012 is connected with the wear-resistant sealing sleeve 202. The surface of the threaded tube 2012 is threadedly sleeved with a threaded cover 2011, and the inner wall of the threaded cover 2011 is fixed with an elastic column 2014. A sealing pressure column 2013 is fixed at one end of the elastic column 2014. The surface of the sealing pressure column 2013 fits tightly with the surface of the sealing filler 203.

[0025] Before use, the sealing filler 203 can be filled into the wear-resistant sealing sleeve 202 through the threaded tube 2012, so that the sealing filler 203 squeezes the wear-resistant sealing sleeve 202. Even if the wear-resistant sealing sleeve 202 becomes thinner due to wear, it can still fit tightly with the ball 104. At the same time, since the wear-resistant sealing sleeve 202 is made of a wear-resistant carbon fiber layer, the wear-resistant sealing sleeve 202 can be made more wear-resistant.

[0026] Furthermore, if Figure 2As shown, a positioning and mounting mechanism 3 is circumferentially arranged on the surface of the outer sleeve 1 and the connecting tube 102, and the positioning and mounting mechanism 3 is composed of a positioning and mounting component 301 and a sealing gasket 302. The sealing gasket 302 is adhered to the center position of the surface of the outer sleeve 1 and the connecting tube 102, and a positioning and mounting component 301 is circumferentially arranged on the surface of the outer sleeve 1 and the connecting tube 102. Positioning studs 3011, nuts 3012 and gaskets 3013 are arranged inside the positioning and mounting component 301.

The nuts 3012 and the positioning studs 3011 are threadedly matched with each other, and gaskets 3013 are sleeved on the surface of the positioning studs 3011.

[0027] When in use, place the pipe with the flange on one side of the outer sleeve 1 and the connecting pipe 102 respectively, so that the installation hole of the pipe is put on the surface of the positioning stud 3011, and the pipe is quickly positioned and docked. Then, the gasket 3013 is put on the surface of the positioning stud 3011, and then the nut 3012 is put on the surface of the positioning stud 3011. Then, the nut 3012 is rotated, and the pipe and the spherical compensator are connected under the thread cooperation of the nut 3012 and the positioning stud 3011. The pipe and the spherical compensator are sealed under the action of the sealing gasket 302, so as to realize the function of the spherical compensator to facilitate the positioning and connection of the pipe.

[0028] Furthermore, if Figure 4 As shown, a compensating adjustment mechanism 4 is circumferentially arranged on the surface of the pressure plate 101, and the interior of the compensating adjustment mechanism 4 includes a baffle 401 and an adjusting member 402. A baffle 401 is circumferentially arranged on the outer side of the connecting tube 102, and an adjusting member 402 is arranged on one side of the baffle 401. A telescopic rod 4021, an adjusting screw 4022 and an adjusting barrel 4023 are arranged inside the adjusting member 402. The surface of the baffle 401 is rotatably connected with the adjusting barrel 4023, and the surface of the pressure plate 101 is fixed with an adjusting screw 4022, and the adjusting screw 4022 and the adjusting barrel 4023 are threadedly matched with each other. The surface of the baffle 401 is fixed with a telescopic rod 4021, and one end of the telescopic rod 4021 is fixedly connected to the inner wall of the pressure plate 101.

[0029] When in use, the spherical compensator utilizes the angular displacement of the sphere 104 to absorb or compensate for the lateral displacement of the pipeline in one or more directions. When the sphere 104 rotates, it drives the connecting pipe 102 to move synchronously. At this time, the adjusting screw 4023 can be rotated, and the adjusting screw 4023 is driven to move under the cooperation of the threads of the adjusting screw 4023 and the adjusting screw 4022, and the baffle 401 is driven to move. Under the action of the telescopic rod 4021, the baffle 401 is guided, and the position of the baffle 401 is adjusted so that the baffle 401 blocks the connecting pipe 102, limiting the rotation range of the connecting pipe 102, thereby changing the compensation range of the spherical compensator to realize the compensation range adjustment function of the spherical compensator.

[0030] Working principle: When in use, first place the pipe with flange on one side of the outer sleeve 1 and the connecting pipe 102 respectively, so that the installation hole of the pipe is put on the surface of the positioning stud 3011, and the pipe is quickly positioned and docked, and then the gasket 3013 is put on the surface of the positioning stud 3011, and then the nut 3012 is put on the surface of the positioning stud 3011, and then the nut 3012 is rotated, and the pipe and the spherical compensator are connected under the thread cooperation of the nut 3012 and the positioning stud 3011, and the pipe and the spherical compensator are sealed under the action of the sealing gasket 302, so as to realize the function of the spherical compensator to facilitate the positioning and connection of the pipe, thereby improving the convenience of the spherical compensator when connecting the pipe.

[0031] Before use, the sealing filler 203 can be filled into the wear-resistant sealing sleeve 202 through the threaded tube 2012, so that the sealing filler 203 squeezes the wear-resistant sealing sleeve 202. Even if the wear-resistant sealing sleeve 202 becomes thinner due to wear, it can still fit tightly with the sphere 104. At the same time, since the wear-resistant sealing sleeve 202 is made of a wear-resistant carbon fiber layer, the wear-resistant sealing sleeve 202 can be made more wear-resistant. Then, the threaded cover 2011 can be covered on the surface of the threaded tube 2012, so that the sealing pressure column 2013 fits tightly with the sealing filler 203, and then the threaded cover 2011 is rotated. The threaded cover 2011 is fixed under the cooperation of the threads of the threaded cover 2011 and the threaded tube 2012. At this time, the elastic column 2014 moves toward the side of the sealing filler 203 with the threaded cover 2011, so that the elastic column 2014 squeezes the sealing pressure column 2013, and drives the sealing pressure column 2013 to squeeze the sealing filler 203, so that the wear-resistant sealing sleeve 202 is always in close contact with the ball 104, so as to realize the efficient wear-resistant sealing function of the spherical compensator, so that the wear-resistant sealing sleeve 202 is not easy to affect the sealing effect of the spherical compensator due to wear when the spherical compensator is in use.

[0032] When the spherical compensator is in use, it utilizes the angular displacement of the sphere 104 to absorb or compensate for the lateral displacement of the pipeline in one or more directions. When the sphere 104 rotates, it drives the connecting pipe 102 to move synchronously. At this time, the adjusting screw 4023 can be rotated, and the adjusting screw 4023 is driven to move under the cooperation of the threads of the adjusting screw 4023 and the adjusting screw 4022, and the baffle 401 is driven to move. Under the action of the telescopic rod 4021, the baffle 401 is guided, and the position of the baffle 401 is adjusted so that the baffle 401 blocks the connecting pipe 102 and limits the rotation amplitude of the connecting pipe 102, thereby changing the compensation range of the spherical compensator to realize the compensation range adjustment function of the spherical compensator, thereby improving the flexibility of the spherical compensator when in use, and finally completing the use of the spherical compensator.
