Description

Technical Field

[0001] The embodiments disclosed herein relate to the field of compensator technology, and more specifically, to an anti-pull-out corrugated compensator. Background Technology

[0002] A bellows compensator is a device used in piping systems to compensate for pipeline deformation. Its main function is to compensate for problems such as pipeline expansion and contraction, angular deviation, and axial displacement. The working principle of a bellows compensator is to use its own elasticity to resist the axial, lateral, and angular displacement of the pipeline caused by thermal deformation, mechanical deformation, and various mechanical vibrations. The bellows of the compensator are flexible and elastic, capable of withstanding certain pressure and bending, thus ensuring the normal operation of the compensator during work.

[0003] According to a published report (publication number: CN 206904451U), a corrugated compensator includes a housing, a guide tube, a bellows, and a retaining ring. The guide tube is fitted inside the through hole of the housing, and the bellows is fitted and fixed on the outside of the circumference of the housing. The retaining ring is configured as a circular ring structure. The retaining ring is welded and fixed to the inner wall of the housing. The retaining ring is welded and fixed to the end of the guide tube.

[0004] In the aforementioned application, the cooperation between the shell and the bellows assembly makes it difficult to ensure the bellows is stably fixed during installation. This causes the bellows to come off the predetermined connection position when the pressure or tension is too high in the pipeline system. Therefore, we propose an anti-pull-out bellows compensator. Utility Model Content

[0005] To overcome the above-mentioned defects, the embodiments of this disclosure provide an anti-pull-out corrugated compensator, which solves the problem that the corrugated pipe cannot be prevented from pulling out in the related art.

[0006] According to one aspect, at least one embodiment of this disclosure provides an anti-pull-out corrugated compensator, including a corrugated pipe, one end of which is fixedly connected to a connecting pipe, one end of which is fixedly connected to a flange, and an anti-pull-out mechanism is provided on the circumferential surface of the corrugated pipe.

[0007] The anti-pull-out mechanism includes a support box, one end of which is inserted into the circumferential surface of the bellows. A control shaft is rotatably connected through the top of the support box, and a driving bevel gear is fixedly connected through the circumferential surface of the control shaft. An installation shaft is rotatably connected through the side of the support box, and a driven bevel gear is fixedly connected through the circumferential surface of the installation shaft. A threaded sleeve is fixedly connected to the circumferential surface of the flange, and the interior of the threaded sleeve is threadedly connected to the circumferential surface of the installation shaft.

[0008] For example, in at least one embodiment of this disclosure, an anti-pull-out corrugated compensator further includes: a fixing nut one threadedly connected to the circumferential surface of the mounting shaft, and a fixing nut two threadedly connected to the circumferential surface of the mounting shaft, the purpose of which is to stably fix the adjusted flange.

[0009] A handle is fixedly connected to one end of the control shaft, which is intended to facilitate the operator to turn the control shaft.

[0010] The circumferential surface of the driving bevel gear meshes with the circumferential surface of the driven bevel gear to ensure that the rotation of the driving bevel gear can drive the driven bevel gear to rotate.

[0011] The number of the driving bevel gear, driven bevel gear, and grip is set to two, and they are symmetrical to each other along the vertical central axis of the bellows. The purpose is to improve stability through multiple components.

[0012] According to another aspect, at least one embodiment of this disclosure also provides an anti-pull-out corrugated compensator, including a buffer mechanism. The buffer mechanism includes a support plate, the side of which is fixedly connected to the circumferential surface of a flange. A sliding column is slidably connected through the side of the support plate. A fixed plate is fixedly connected to the circumferential surface of the sliding column. A buffer sleeve is fixedly connected to the side of the fixed plate. A buffer spring is fixedly connected inside the buffer sleeve. A buffer plate is fixedly connected to the end of the buffer spring away from the inside of the buffer sleeve. The function of the buffer mechanism is to reduce the vibration amplitude of the bellows and extend the service life of the corrugated compensator.

[0013] For example, in at least one embodiment of this disclosure, an anti-pull-out corrugated compensator further includes: the side of the buffer sleeve is fixedly penetrated by the circumferential surface of the mounting shaft, and the side of the buffer plate is in contact with the circumferential surface of the corrugated pipe, the purpose of which is to ensure the stability of the buffer sleeve.

[0014] The side of the buffer plate is elastically connected to the inside of the buffer sleeve by a buffer spring. The buffer spring is initially in a relaxed state, which is intended to better reduce pressure through the buffer spring and the buffer plate.

[0015] The number of sliding columns and buffer sleeves is set to two, and they are symmetrical to each other along the vertical central axis of the bellows, which is intended to provide double buffering for the bellows.

[0016] The number of buffer springs and buffer plates is set to several, and they are symmetrical to each other along the vertical central axis of the bellows, in order to improve the buffering effect.

[0017] The beneficial effects of the embodiments disclosed herein are as follows:

[0018] 1. In this utility model, through the cooperation between the control shaft, mounting shaft, and fixing nut one of the anti-pull-out mechanism, when the bellows is needed, the operator turns the handle, and through the meshing of the active bevel gear and the driven bevel gear, the mounting shaft rotates and drives the threaded sleeve to move. At this time, the operator moves the flange to the required position according to the work requirements, and then fixes the flange stably with fixing nut one and fixing nut two. This design achieves the effect of preventing the bellows from pulling out, preventing the bellows from coming off the connection position under high pressure or high tension, and ensuring the safe operation of the bellows.

[0019] 2. In this utility model, through the mutual fitting of components such as the support plate, buffer sleeve, and buffer plate of the buffer mechanism, while the flange is installed and fixed, the fixing plate is installed through the sliding column, so that the buffer sleeve is installed in the designated position. When the bellows is working, the inside of the bellows will be subjected to impact force, which will generate vibration. The buffer plate will be subjected to vibration force and will compress the buffer spring slightly. Under the action of the buffer spring and the buffer plate, the impact force generated by the vibration is reduced through the reaction elastic force, thereby reducing the vibration amplitude of the bellows. This design achieves the effect of buffering the bellows during operation and effectively extends the service life of the bellows. Attached Figure Description

[0027] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present disclosure and are not intended to limit the scope of the disclosure.

[0028] To keep the drawings concise, each drawing only schematically shows the parts relevant to the disclosure; these do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of components with the same structure or function is schematically shown, or only one is labeled. In this document, "one" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."

[0029] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linkage" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this disclosure based on the specific circumstances.

Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0031] In the description of this embodiment, terms such as "upper," "lower," "left," and "right" are based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this disclosure.

[0032] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0033] like Figures 1-5 As shown, it illustrates an anti-pull-out corrugated compensator in one embodiment of the present disclosure, including a corrugated pipe 1, a connecting pipe 2 fixedly connected to one end of the corrugated pipe 1, a flange 3 fixedly connected to one end of the connecting pipe 2, and an anti-pull-out mechanism 4 provided on the circumferential surface of the corrugated pipe 1.

[0034] The anti-pull-out mechanism 4 includes a support box 41, one end of which is inserted into the circumferential surface of the bellows 1. A control shaft 42 is rotatably connected through the top of the support box 41. A drive bevel gear 43 is fixedly connected through the circumferential surface of the control shaft 42. An installation shaft 44 is rotatably connected through the side of the support box 41. A driven bevel gear 45 is fixedly connected through the circumferential surface of the installation shaft 44. A threaded sleeve 46 is fixedly connected to the circumferential surface of the flange 3. The inside of the threaded sleeve 46 is threadedly connected to the circumferential surface of the installation shaft 44.

[0035] In some examples, the mounting shaft 44 is threaded with a fixing nut 47 and a fixing nut 48, the purpose of which is to stably fix the adjusted flange 3.

[0036] A handle 49 is fixedly connected to one end of the control shaft 42, which is intended to facilitate the operator to turn the control shaft 42.

[0037] The circumferential surface of the driving bevel gear 43 meshes with the circumferential surface of the driven bevel gear 45 to ensure that the rotation of the driving bevel gear 43 can drive the driven bevel gear 45 to rotate.

[0038] The number of driving bevel gear 43, driven bevel gear 45 and grip 49 is set to two, and they are symmetrical to each other along the vertical central axis of bellows 1. The purpose is to improve stability through multiple components.

[0039] For example, such as Figures 1-5As shown, when the bellows 1 is needed, the operator turns the handle 49 to rotate the control shaft 42. The rotation of the control shaft 42 drives the drive bevel gear 43 to rotate. The drive bevel gear 43 meshes with the driven bevel gear 45, causing the driven bevel gear 45 to rotate. The rotation of the driven bevel gear 45 drives the mounting shaft 44 to rotate. The rotation of the mounting shaft 44 drives the threaded sleeve 46 to move. At this time, the operator moves the flange 3 to the required position according to the work requirements. Then, the flange 3 is stably fixed by fixing nut 1 47 and fixing nut 2 48.

[0040] like Figures 1-5 As shown, this illustrates another embodiment of the anti-pull-out corrugated compensator, which is largely the same as the above-described technical solution. Therefore, only the differences are described in detail. It includes a buffer mechanism 5, which includes a support plate 51. The side of the support plate 51 is fixedly connected to the circumferential surface of the flange 3. A sliding column 52 is slidably connected through the side of the support plate 51. A fixing plate 53 is fixedly connected to the circumferential surface of the sliding column 52. A buffer sleeve 54 is fixedly connected to the side of the fixing plate 53. A buffer spring 55 is fixedly connected inside the buffer sleeve 54. A buffer plate 56 is fixedly connected to the end of the buffer spring 55 away from the inside of the buffer sleeve 54. The function of the buffer mechanism 5 is to reduce the vibration amplitude of the bellows 1 and extend the service life of the corrugated compensator.

[0041] In some examples, the buffer sleeve 54 is fixedly penetrated by the side of the mounting shaft 44, and the side of the buffer plate 56 contacts the circumferential surface of the bellows 1, the purpose of which is to ensure the stability of the buffer sleeve 54.

[0042] The side of the buffer plate 56 is elastically connected to the inside of the buffer sleeve 54 through the buffer spring 55. The buffer spring 55 is initially in a relaxed state, which is intended to reduce pressure better through the buffer spring 55 and the buffer plate 56.

[0043] The number of sliding columns 52 and buffer sleeves 54 is set to two, and they are symmetrical to each other along the vertical central axis of the bellows 1. The purpose is to provide double buffering for the bellows 1.

[0044] The number of buffer springs 55 and buffer plates 56 is set to several, and they are symmetrical about each other along the vertical central axis of the bellows 1, in order to improve the buffering effect.

[0045] For example, such as Figures 1-5As shown, while the flange 3 is installed and fixed, the fixing plate 53 is installed through the sliding column 52, so that the buffer sleeve 54 is installed in the designated position. When the bellows 1 is working, the inside of the bellows 1 will be subjected to impact force, which will generate vibration. The generated vibration force will be transmitted to the surface of the bellows 1. At this time, the buffer plate 56 is in contact with the bellows 1. The vibrating bellows 1 will impact the side of the buffer plate 56. The buffer plate 56 will be subjected to vibration force and will compress the buffer spring 55 slightly. Under the action of the buffer spring 55 and the buffer plate 56, the impact force generated by the vibration is reduced through the reaction elastic force, thereby reducing the vibration amplitude of the bellows 1.

[0046] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
