Description

Technical Field

[0001] This utility model relates to the field of pipeline technology, and in particular to a corrugated compensator. Background Technology

[0002] A bellows compensator is a type of compensating element. It utilizes the effective expansion and contraction of its main working body, the bellows, to absorb dimensional changes in pipelines, ducts, and containers caused by thermal expansion and contraction, or to compensate for axial, lateral, and angular displacements of pipelines, ducts, and containers. It can also be used for noise reduction and vibration damping. It has wide applications in modern industry.

[0003] A corrugated compensator disclosed in Chinese Patent CN215294089U (Publication No.) allows for adjustment of the expansion and contraction of the bellows by adjusting the bolt assembly to bring the first and second limiting members closer together and further apart. The first and second limiting members can also abut against each other to support the bellows when it is compressed to its limit, thereby minimizing damage to the bellows caused by extrusion pressure in this state. This improves the ease of adjustment of the bellows compensator in application and also increases its working displacement cycle life.

[0004] However, compared with existing technologies in related fields, both nuts and screws require workers to use special tools to control the expansion and contraction of the bellows for adjustment, which makes the adjustment process inconvenient. At the same time, the displacement efficiency between a single screw and nut is low, which indirectly affects the installation efficiency when connecting to the pipeline. Utility Model Content

[0005] The purpose of this invention is to at least solve one of the aforementioned technical defects.

[0006] The purpose of this utility model is to overcome the shortcomings of the prior art, solve the problems mentioned in the background art, and provide a corrugated compensator.

[0007] The purpose of this utility model is achieved through the following technical solution: a corrugated compensator, including a corrugated component, with flanges fixedly provided at both ends of the corrugated component, and multiple adjusting components provided between the two flanges. Each adjusting component includes a support component, with a support component fixedly provided on the corresponding side of each of the two flanges, and an adjusting screw rotatably provided between the two support components. Nuts are threadedly connected to both ends of the adjusting screw, and positioning blocks for limiting the rotation of the nuts are fixedly provided on the two support components at the positions corresponding to the nuts. A pressure rod is slidably connected to the middle of the adjusting screw.

[0008] Preferably, the support member is L-shaped.

[0009] The shape of the support component was described by adopting the above technical solution.

[0010] Preferably, the support member has a rotating hole at the position corresponding to the adjusting screw, and the diameter of the rotating hole is larger than the diameter of the adjusting screw.

[0011] By adopting the above technical solution and utilizing the rotating hole, the support component will not be affected by the adjusting screw when the adjusting screw rotates.

[0012] Preferably, the adjusting screw is a left- or right-hand threaded rod, and the two nuts on the adjusting screw are both adapted to the adjusting screw.

[0013] By adopting the above technical solution, when the adjusting screw rotates, the two nuts can be brought closer or further apart by using two threads in different directions, thereby increasing the displacement speed of the two adjacent support components.

[0014] Preferably, the positioning block has a groove on the side near the nut, and the groove is half a hexagon.

[0015] By adopting the above technical solution, the rotation of the nut can be restricted by using a half-hexagonal groove, so that the two nuts can move closer or further apart, without affecting the normal expansion and contraction of the corrugated parts.

[0016] Preferably, the adjusting screw has a movable hole at the position corresponding to the pressure rod, and both ends of the pressure rod are fixed with spherical parts, the diameter of which is larger than the diameter of the movable hole.

[0017] By adopting the above technical solution, the pressure rod makes it easy for workers to rotate the adjusting screw, while the spherical part prevents the pressure rod from disengaging from the adjusting screw.

[0018] Compared with the prior art, the present invention has the following advantages:

[0019] This bellows compensator, through the setting of adjustment components, achieves the following: the pressure rod allows workers to easily rotate the adjustment screw without the need for special tools, effectively improving the convenience of bellows compensator adjustment; at the same time, the left and right threaded adjustment screw can control the two nuts to move closer or further apart, thereby increasing the displacement speed of the two adjacent support components, and thus indirectly improving the installation efficiency when connecting to pipelines.

[0028] Additional aspects and advantages of this invention will be further set forth in the description which follows in conjunction with the accompanying drawings, in part of which will be obvious from the description or may be learned by practice of the invention.

[0029] like Figure 1-4 As shown, a corrugated compensator includes a corrugated component 1, with flanges 2 fixedly mounted at both ends of the corrugated component 1. Multiple adjusting components 3 are disposed between the two flanges 2. Each adjusting component 3 includes a support member 301, with a support member 301 fixedly mounted on a corresponding side of each of the two flanges 2. An adjusting screw 302 is rotatably mounted between the two support members 301. The support member 301 is L-shaped, and a rotating hole is provided on the support member 301 corresponding to the position of the adjusting screw 302. The diameter of the rotating hole is larger than the diameter of the adjusting screw 302. This rotating hole ensures that the support member 301 is not affected by the adjusting screw 302 when it rotates. The adjusting screw 302 is a left- or right-hand threaded rod. Two nuts 303 on the adjusting screw 302 are adapted to the adjusting screw 302. Nuts 303 are threadedly connected to both ends of the adjusting screw 302. When the adjusting screw 302 rotates, the two nuts 303 can be moved closer or further apart using the two threads in different directions. To increase the displacement speed of two adjacent support members 301, each support member 301 is fixedly equipped with a positioning block 304 at the position corresponding to the nut 303 to restrict the rotation of the nut 303. The side of the positioning block 304 closest to the nut 303 has a groove 3041, which is semi-hexagonal in shape. This semi-hexagonal groove 3041 restricts the rotation of the nut 303, allowing the two nuts 303 to move closer or further apart without affecting the rotation speed. For the normal extension and retraction of the corrugated part 1, a pressure rod 305 is slidably connected at the middle of the adjusting screw 302. A movable hole 3021 is opened on the adjusting screw 302 corresponding to the position of the pressure rod 305. Both ends of the pressure rod 305 are fixed with spherical parts 3051. The diameter of the spherical parts 3051 is larger than the diameter of the movable hole 3021. The pressure rod 305 makes it easy for the operator to rotate the adjusting screw 302. At the same time, the spherical parts 3051 prevent the pressure rod 305 from disengaging from the adjusting screw 302.

[0030] The work process is as follows:

[0031] S1. During adjustment, the adjusting screw 302 can be rotated by sliding the pressure rod 305 back and forth.

[0032] S2. When the adjusting screw 302 rotates, the two nuts 303 can be brought closer or further apart by using two threads in different directions, thereby increasing the displacement speed of the two adjacent support members 301, and thus indirectly increasing the compression speed of the bellows 1.

[0033] S3. By using a half-hexagonal groove 3041, the rotation of the nut 303 can be restricted, so that the two nuts 303 can move closer or further apart, without affecting the normal expansion and contraction of the corrugated part 1.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
