Description

Technical Field

[0001] The utility model mainly relates to the field of corrugated compensators, and in particular to a compensator with high impact resistance. Background Art

[0002] A bellows compensator is a type of compensating element. It utilizes the effective expansion and contraction of its working bellows to absorb dimensional changes caused by thermal expansion and contraction in pipelines, conduits, and containers, as well as axial, lateral, and angular displacement of the compensator lines, conduits, and containers. It can also be used to reduce noise and vibration.

[0003] During the operation of the specific embodiment, the inventors found the following defects:

[0004] However, when the length of the bellows compensator is long, after the pipeline drives the bellows compensator to move, the bellows compensator is dislocated and the bellows compensator produces a large arc, it is easy for the liquid or gas inside the pipeline to impact the bellows compensator, causing the bellows compensator to vibrate greatly, affecting the transportation of liquid or gas.

[0024] To facilitate understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings. Several embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0025] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "page", "bottom", "inside", "outside", "clockwise", "counterclockwise", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0026] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of this utility model, "plurality" means two or more, unless otherwise specifically defined.

[0027] In this utility model, unless otherwise expressly specified or limited, the terms "installed," "connected," "connected," "fixed," "provided with," "provided on," etc. should be understood in a broad sense. For example, they may refer to fixed connection, detachable connection, or integral connection; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; or internal communication between two components. Those skilled in the art will be able to understand the specific meanings of the above terms in this utility model based on specific circumstances. Example

[0028] Refer to the attached Figure 1-4A compensator with high impact resistance includes a connecting flange 1, a connecting hole 2 is opened inside the connecting flange 1, the number of the connecting flanges 1 is set to two, a compensator body 3 is arranged between the two connecting flanges 1, an intermediate ring 4 is arranged in the middle of the compensator body 3, and a connecting block 5 is arranged on the outer wall of the intermediate ring 4. Tension springs 6 are arranged at both ends of the connecting block 5, and the tension spring 6 is connected to the connecting flange 1. A card slot 7 is opened on the outer wall of both sides of the connecting flange 1, and a mounting structure 8 and a universal rotation structure 9 are installed between the two card slots 7.

[0029] Furthermore, the number of the tension springs 6 is set to two. When the outer wall of the intermediate ring 4 is displaced in the pipeline on both sides, the two tension springs 6 in a circular array will drive the compensator bodies 3 on both sides of the intermediate ring 4 to bend in different directions, thereby avoiding a large bending angle of the compensator body 3 and making the bending arc of the compensator body 3 larger to block the gas or liquid inside the compensator body 3, causing the gas or liquid to impact the compensator body 3.

[0030] Furthermore, the mounting structure 8 includes a connecting tube 801 and a threaded rod 804. A first clamping block 802 is provided on the top of the connecting tube 801. The first clamping block 802 is engaged with the card slot 7. A mounting hole 803 is provided inside the connecting tube 801. An internal threaded ring is provided inside the mounting hole 803. The number of connecting tubes 801 is set to two. Both ends of the threaded rod 804 are threadedly connected to the internal threaded ring inside the mounting hole 803. A rotating handle 805 is provided on the outer wall in the middle of the threaded rod 804. When the compensator body 3 needs to be installed, When the compensator body 3 is tightened, the connecting flanges 1 at both ends of the compensator body 3 are pressed against the flanges of the pipeline and fixed with bolts. After the compensator body 3 is installed, the mounting structure 8 is removed from the outer wall of the connecting flange 1.

[0031] Furthermore, the universal rotation structure 9 includes a positioning shaft 901 and a positioning ring 904. The top of the positioning shaft 901 is provided with a second clamping block 902, and the second clamping block 902 is engaged with the clamping slot 7. The bottom of the positioning shaft 901 is provided with a threaded ring 903. The number of the positioning shafts 901 is set to two. Limiting columns 906 are provided on both sides of the positioning ring 904. Reset springs 905 are provided on both sides of the positioning ring 904. One end of the reset spring 905 is rotatably connected to a threaded tube 907, and the threaded tube 907 is threadedly connected to the threaded ring 903. When the mounting structure 8 is removed , insert the second block 902 into the interior of the card slot 7, and then replace the limiting columns 906 of different lengths according to the need to limit the extension and contraction length of the compensator body 3, and then place the positioning ring 904 between the two positioning shafts 901, connect the threaded tube 907 with the threaded ring 903, and fix the positioning ring 904. When the compensator body 3 bends, it will also drive the reset spring 905 to bend, and the positioning shaft 901 may drive the threaded tube 907 to move toward the middle. After the threaded tube 907 is fitted with the limiting column 906, the compensator body 3 can no longer continue to bend toward the middle, thereby limiting the compensator body 3.

[0032] The above-mentioned embodiments only express a certain implementation method of the utility model, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the utility model, which all fall within the scope of protection of the utility model. Therefore, the scope of protection of the utility model patent shall be based on the attached claims.
