Description

Technical Field

[0001] The utility model relates to the technical field of valve body assembly, in particular to a centerline valve assembly device. Background Art

[0002] A centerline valve is a specially designed valve with the inlet and outlet aligned on the same axis. It is widely used in piping systems in industries such as industry, construction, and water conservancy. It consists of a valve body and a spool opening and closing mechanism. During the production process, these two mechanisms are assembled separately. Due to the circular shape of the valve body, centerline valve assembly typically requires two people to coordinate safely and stably complete the assembly. The application number (202221069999.1) discloses assembly equipment for specialized piping for water conservancy valves.

[0003] In the process of realizing the present utility model, the inventors found that there are at least the following problems in the prior art that have not been solved: the above-mentioned public patent uses three stop structures to limit the appearance of the valve body structure of the centerline valve. Although the stability is greatly improved, when assembling the valve core opening and closing structure, the valve core opening and closing structure cannot be easily assembled to the valve body structure due to the large temporary space of the limiting structure. Secondly, there are many limiting structures. After the centerline valve is assembled, it is not conducive to the rapid transfer of the assembled centerline valve, thereby greatly reducing the assembly efficiency of the device for the centerline valve, and it is in urgent need of improvement. Therefore, we propose a centerline valve assembly device. Utility Model Content

[0004] The purpose of the utility model is to provide a centerline valve assembly device to solve the problems raised in the background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a centerline valve assembly device, comprising a centerline valve, a clamping roller structure 1 and a clamping roller structure 2, the clamping roller structure 1 and the clamping roller structure 2 are distributed on both sides of the bottom of the centerline valve, the clamping roller structure 2 comprises a load-bearing roller, a clamping ring 1 and a clamping ring 2 which are sleeved on the outside of the load-bearing roller, the two ends of the load-bearing roller are rotatably connected to the support through an axis, the support is fixed to the base surface by bolts, and a screw is arranged between the clamping ring 1 and the clamping ring 2.

[0011] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0012] 1.

Subsequently, a screw and a nut are used to clamp the clamp ring 1 and the clamp ring 2, so that the clamp ring 1 and the clamp ring 2 limit the axial movement of the centerline valve, thereby improving the stability during the assembly of the centerline valve.

[0013] 2. The technical solution of the present application supports the centerline valve through two load-bearing rollers.

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0019] Example 1, as Figure 1-2 As shown, the utility model provides a technical solution: a centerline valve assembly device, including a centerline valve 1, a clamping roller structure 3 and a clamping roller structure 2 4, the clamping roller structure 3 and the clamping roller structure 2 4 are distributed on both sides of the bottom of the centerline valve 1, the clamping roller structure 3 and the clamping roller structure 2 4 have the same structural composition, the clamping roller structure 2 4 includes a load-bearing roller 401, a clamping ring 1 402 and a clamping ring 2 403 sleeved on the outside of the load-bearing roller 401, both ends of the load-bearing roller 401 are rotatably connected to the support 404 through an axis, the support 404 is fixed to the surface of the base 2 by bolts, a screw 8 is provided between the clamping ring 1 402 and the clamping ring 2 403, and three matching holes 5 of the same size are opened around the clamping ring 1 402 and the clamping ring 2 403, the screw 8 is embedded in the matching hole 5, and a nut 9 is threadedly connected to one end of the screw 8.

[0020] In a specific embodiment of the present invention, the distance between the first clamping roller structure 3 and the second clamping roller structure 4 is adjusted according to the diameter of the centerline valve 1, so that the line connecting the centers of the circles of the first clamping roller structure 3 and the second clamping roller structure 4 is located below the center of the circle of the centerline valve 1 and the bottom of the centerline valve 1 does not contact the base 2. The adjustment method is: adjusting the position of the anchor bolt 6 of the support 404 and the threaded hole 7, thereby adjusting the distance between the center lines of the first clamping roller structure 3 and the second clamping roller structure 4;

[0021] Place the centerline valve 1 on the surface of the load-bearing roller 401 of the clamping roller structure 1 3 and the clamping roller structure 2 4, and use the rolling mechanism of the load-bearing roller 401 to adjust the assembly direction of the centerline valve 1. After the assembly direction is determined, place the clamping ring 1 402 and the clamping ring 2 403 close to the front and rear end faces of the centerline valve 1, and pass the screw 8 through the matching holes 5 of the clamping ring 1 402 and the clamping ring 2 403 at the same time. Finally, use the nut 9 to tighten the clamping ring 1 402 and the clamping ring 2 403, so that the clamping ring 1 402 and the clamping ring 2 403 limit the axial movement of the centerline valve 1. After the centerline valve 1 is assembled, loosen the screw 8 and the nut 9, and the assembled centerline valve 1 can be directly transferred through the lifting mechanism.

[0022] In the preferred technical solution, a number of threaded holes 7 are equidistantly provided on the surface of the base 2, and anchor bolts 6 are embedded on the front and back surfaces of each support 404. The anchor bolts 6 are threadedly connected to the threaded holes 7. The position of the anchor bolts 6 of the support 404 and the threaded holes 7 is adjusted to adjust the distance between the center lines of the clamping roller structure 1 3 and the clamping roller structure 2 4, so as to adapt to the support of centerline valves 1 of different sizes.

[0023] In the preferred technical solution, the two sides of the bottom of the centerline valve 1 are in contact with the surfaces of the load-bearing rollers 401 of the clamping roller structure 1 3 and the clamping roller structure 2 4 respectively, and the front and rear end faces of the centerline valve 1 are in contact with the surfaces of the clamping ring 1 402 and the clamping ring 2 403 respectively, and the clamping ring 1 402 and the clamping ring 2 403 are pressed tightly, so that the clamping ring 1 402 and the clamping ring 2 403 limit the axial movement of the centerline valve 1, thereby improving the stability of the centerline valve 1 during assembly.

[0024] In the preferred technical solution, flange rings are fixedly provided at both the front and rear ends of the centerline valve 1. The flange rings are used for assembly between the centerline valve 1 and the pipeline. The ring body widths of clamp ring 1 402 and clamp ring 2 403 are consistent with the ring body width of the flange ring, so as to avoid the ring body widths of clamp ring 1 402 and clamp ring 2 403 exceeding the ring body width of the flange ring, thereby avoiding blocking the inner cavity of the centerline valve 1 and facilitating the assembly of the valve core into the centerline valve 1.

[0025] In summary, this embodiment provides a centerline valve 1 that is supported by rolling load-bearing rollers 401 on both sides, and is auxiliaryly fixed to the centerline valve 1 with two clamping rings, thereby achieving convenient and adjustable assembly of the centerline valve 1, a stable assembly process, and convenient transfer after assembly. The centerline valve 1 assembly equipment greatly improves the assembly efficiency of the valve core and the adjustment part structure of the centerline valve 1.
