The technical scheme of the invention will be further described with reference to the examples and the accompanying drawings.

Examples

In some large piping systems, the distal tubing after a long distance is extended can undergo slight deformation under the influence of its own weight, and errors can also occur during the installation of the fixed tubing over long distances. As shown in fig. 14, under the influence of various error stacks, the upper pipe and the lower pipe may not be on the same axis, and the two pipes cannot be connected by using a conventional flange.

Meanwhile, because the distance between the openings of the two pipelines is about 20 cm, the pipelines with shorter distance are not suitable for connection by using flange type corrugated pipes.

The present application thus provides a flange compensator provided with a rotating structure 10, the rotating structure 10 comprising a fixed tube 11 and an adjusting tube 12 coaxially arranged and rotatable relative to each other, the fixed tube 11 being eccentrically provided with a first connecting tube 20, the adjusting tube 12 being eccentrically provided with a second connecting tube 30. The axis of rotation of the fixed tube 11 and the adjusting tube 12 is set as a fixed axis, and when the first connecting tube 20 is connected to one pipe 70, the adjusting tube 12 rotatably connected to the fixed tube 11 is rotated, and at this time, the second connecting tube 30 mounted on the adjusting tube 12 is rotated around the fixed axis. Because the second connecting pipe 30 is eccentric relative to the fixed shaft, the second connecting pipe 30 can rotate to a position coaxial with the other pipeline 70, and the second connecting pipe 30 and the other pipeline 70 can be connected with two different shafts or coaxial pipelines 70 through flange connection.

Specifically, referring to fig. 1 to 4, the flange compensating device includes a rotating structure 10, a first connecting pipe 20 and a second connecting pipe 30, wherein the first connecting pipe 20 is used for performing flange connection with a pipe 70, the first connecting pipe 20 is fixedly connected with a fixed pipe 11, and the first connecting pipe 20 and the fixed pipe 11 are eccentrically arranged. The second connecting pipe 30 of the adjusting pipe 12 is used for being in flange connection with the other pipeline 70, the second connecting pipe 30 is fixedly connected with the adjusting pipe 12, and the second connecting pipe 30 and the adjusting pipe 12 are eccentrically arranged. The fixed tube 11 and the adjusting tube 12 are coaxially disposed and rotatably connected.

In use, with reference to FIG. 2, after the spacing of the pipes 70 has been determined, a highly suitable flange compensating device is then placed between the two pipes 70 as shown in FIG. 15. The second connection pipe 30 is connected with one pipe 70 by a bolt, and then the second connection pipe 30 is rotated by rotating the adjusting pipe 12, and when the second connection pipe 30 is rotated to a position coaxial with the other pipe 70, the second connection pipe 30 is connected with the other pipe 70 by a flange by a bolt.

Of course, the distance between the two pipes 70 may not match the height of the flange compensating apparatus, for example, when the distance between the two pipes 70 is smaller than the height of the flange compensating apparatus, one of the pipes 70 needs to be cut and polished, so that the distance between the ends of the two pipes 70 in the vertical direction is the same as the height of the flange compensating apparatus, and the flange compensating apparatus can be inserted between the two pipes 70.

Specifically, in an embodiment of the present invention, referring to fig. 5 to 8, the pipe diameter of the fixed pipe 11 is larger than the pipe diameter of the first connecting pipe 20, and the pipe diameter of the first connecting pipe 20 is larger than or equal to the pipe diameter of the pipe 70. When the fluid in the pipe 70 flows from the pipe 70 to the first connecting pipe 20, the pipe diameter of the first connecting pipe 20 is equal to or larger than the pipe diameter of the pipe 70, and the fluid flowing out of the pipe 70 can enter the first connecting pipe 20 unhindered. Meanwhile, since the pipe diameter of the first connecting pipe 20 is smaller than that of the fixed pipe 11, fluid is not blocked when entering the fixed pipe 11 from the inside of the first connecting pipe 20, and fluid can smoothly flow.

Specifically, in one embodiment of the present invention, in conjunction with fig. 9-12, the tube diameter of the regulator tube 12 is greater than the tube diameter of the second connecting tube 30, as the tube diameter of the second connecting tube 30 is greater than the diameter of the conduit 70. When the fluid in the pipe 70 flows from the pipe 70 to the second connection pipe 30, the pipe diameter of the second connection pipe 30 is equal to or larger than the pipe diameter of the pipe 70, and the fluid flowing out of the pipe 70 can enter the second connection pipe 30 without being blocked. Meanwhile, since the pipe diameter of the second connection pipe 30 is smaller than that of the regulating pipe 12, fluid is not blocked when entering the regulating pipe 12 from the second connection pipe 30, and fluid can smoothly flow.

Referring to fig. 3 to 4, the chamber formed by the fixing tube 11 and the adjusting tube 12 has a tube diameter larger than that of the first connecting tube 20 or the second connecting tube 30, and a flow passage of the fluid is not blocked when the fluid enters the chamber from the first connecting tube 20 or the second connecting tube 30.

Referring to fig. 18, the fixed tube 11 and the adjustment tube 12 of the rotary structure 10 may be connected by a bearing or other rotary member, and the fixed tube 11 and the adjustment tube 12 may smoothly rotate. More specifically, referring to fig. 5 to 8, the fixing tube 11 is a circular tube having an upper opening, and the bottom surface of the fixing tube 11 is closed. The first connecting pipe 20 is fixedly connected to the bottom surface of the fixed pipe 11, and after the first connecting pipe 20 is connected to the bottom surface of the fixed pipe 11, the bottom surface of the fixed pipe 11 is hollowed, so that a through hole with the same pipe diameter as the first connecting pipe 20 is formed on the bottom surface of the fixed pipe 11, and the first connecting pipe 20 is communicated with the fixed pipe 11.

Referring to fig. 9-12, the regulator tube 12 is a circular tube with a lower opening, and the top surface of the regulator tube 12 is closed. The second connecting pipe 30 is fixedly connected to the top surface of the adjusting pipe 12, and after the second connecting pipe 30 is connected to the top surface of the fixed pipe 11, the top surface of the adjusting pipe 12 is hollowed, so that a through hole with the same pipe diameter as the second connecting pipe 30 is formed on the top surface of the adjusting pipe 12, and the second connecting pipe 30 is communicated with the adjusting pipe 12.

Further, in an embodiment of the present invention, the fixed tube 11 and the adjusting tube 12 of the rotating structure 10 are inserted together.

Referring to fig. 2 and 4, the fixed tube 11 and the adjusting tube 12 are rotatably connected, the tube diameter of the adjusting tube 12 is smaller than or equal to the tube diameter of the fixed tube 11, and the adjusting tube 12 is disposed on the inner wall of the fixed tube 11.

Further, in order to prevent leakage at the junction of the adjustment tube 12 and the fixing tube 11, after the adjustment of the adjustment tube 12 and the fixing tube 11 is completed, the adjustment tube 12 and the fixing tube 11 can be welded and fixed.

Preferably, in an embodiment of the present invention, a sealing ring 60 is provided between the adjustment tube 12 and the fixed tube 11. When the adjusting tube 12 and the fixing tube 11 are mounted, the sealing ring 60 is first sleeved on the outer wall of the adjusting tube 12, and then the adjusting tube 12 is pressed into the inner wall of the fixing tube 11. Since the seal ring 60 has a certain elasticity, when the adjustment tube 12 is pressed into the fixed tube 11, the adjustment tube 12 and the fixed tube 11 are sealed well.

It should be noted that, after the adjustment tube 12 and the fixing tube 11 are connected by the connection method as shown in fig. 4, that is, after the adjustment tube 12 and the fixing tube 11 are inserted and the sealing ring 60 is provided, the adjustment tube 12 can still rotate relative to the fixing tube 11.

Further, the adjusting tube 12 and the fixing tube 11 are long tubes, and the sealing ring 60 is disposed at the lower portion of the adjusting tube 12.

Referring to fig. 16 and 17, fig. 16 shows the initial position of the adjusting tube 12, when the distance between the two pipes 70 is larger than the height of the flange compensating device, only one upward force needs to be applied to the adjusting tube 12 (the adjusting tube 12 is pulled upward as shown in fig. 16), the adjusting tube 12 can move upward relative to the fixed tube 11, and at this time, the second connecting tube 30 can approach the other pipe 70, so as to complete the connection between the flange compensating device and the two pipes 70. The sealing ring 60 provided at the lower portion of the adjustment tube 12 can ensure that the adjustment tube 12 can be raised by a sufficient height to complete the connection.

Of course, when fig. 16 is an initial position of the adjustment tube 12, the adjustment tube 12 can also be moved downward relative to the fixed tube 11, and the flange compensator can also be applied to the pipe 70 having a distance between the pipes 70 slightly shorter than the initial length of the flange compensator. If the spacing of the two pipes 70 is less than the minimum spacing of the flange compensators, then the pipes 70 need to be truncated as described above so that the spacing of the pipes 70 and the minimum gap of the flange compensators fit to install the flange compensators.

As shown in fig. 2, a mounting groove 121 is further provided on the outer wall of the adjustment tube 12, the mounting groove 121 being located at the lower portion of the adjustment tube 12, the mounting groove 121 being used for mounting the seal ring 60. When the sealing ring 60 is mounted in the mounting groove 121, the sealing ring 60 can no longer move up and down relative to the adjustment tube 12.

Of course, after the sealing ring 60 is installed in the installation groove 121, one side of the sealing ring 60 away from the adjusting tube 12 can still extend into the installation groove 121, so that the sealing ring 60 can be tightly attached to the inner wall of the fixing tube 11, and the tightness between the fixing tube 11 and the adjusting tube 12 is ensured to be good.

It should be noted that in an embodiment of the present invention, the mounting groove 121 is not provided on the inner wall of the fixed tube 11 to limit the position of the seal ring 60, thereby enabling the rotation and up-and-down movement of the adjustment tube 12 and the seal ring 60 with respect to the fixed tube 11.

Of course, after the sealing ring 60 is provided, the sealing ring 60 provides a large preload so that no leakage occurs between the adjustment tube 12 and the stationary tube 11. In this case, the operator needs to use a tool to perform the operation in order to drive the adjustment tube 12 to rotate relatively.

In order to facilitate the flange connection of both the first connection pipe 20 and the second connection pipe 30 to the pipe 70, the flange compensating device further comprises a first flange 40 and a second flange 50. The first flange 40 is fixedly connected to an end of the first connecting pipe 20 away from the fixed pipe 11, and dense mounting holes 41 are formed in the first flange 40. The second flange 50 is fixedly connected to an end of the second connecting pipe 30 away from the adjusting pipe 12, and dense mounting holes 41 are formed in the second flange 50.

Referring to fig. 13 and 15, the first flange 40 and the second flange 50 are each provided with a dense mounting hole 41, and on the basis of the fewer number of mounting holes provided on the flange on the pipe 70, the mounting holes 41 that fit with the flange on the pipe 70 will always be provided on the first flange 40, and similarly, the mounting holes 41 that fit with the flange on the pipe 70 will be provided on the second flange 50.

In an embodiment of the present invention, the first connection pipe 20 may be connected to the pipe 70 located above or below, and the second connection pipe 30 may be connected to the pipe 70 located above or below.

Preferably, in one embodiment of the present invention, the first connection pipe 20 is adapted to be flanged to the lower pipe 70 and the second connection pipe 30 is adapted to be flanged to the upper pipe 70. When the distance between the two pipes 70 is larger than the initial height of the compensating device to extend the length of the compensating device, the adjusting pipe 12 with smaller pipe diameter is arranged above the adjusting pipe to facilitate the observation of the position of the sealing ring 60, thereby preventing the leakage of powder or the sealing ring 60 between the adjusting pipe 12 and the fixed pipe 11.

Of course, after the connection of the two pipes 70 is completed, filling may be performed in the gap between the adjustment pipe 12 and the fixed pipe 11 so that the sealing of the connection of the flange compensating device is better.

The invention also discloses a pipe system comprising a flange compensator as described above and the flange compensator is used to connect two pipes 70 which are not coaxial or coaxial as shown in fig. 14.

It will be understood that equivalents and modifications will occur to those skilled in the art based on the present invention and its spirit, and all such modifications and substitutions are intended to be included within the scope of the present invention.
