Description
Technical Field
The application relates to an expansion joint, in particular to a pipeline compensator.
Background
An expansion joint refers to a flexible element that effectively functions to compensate for axial deformation. For example, the expansion joint welded on the shell of the fixed tube-plate heat exchanger has large axial flexibility and easy deformation, can compensate the thermal expansion difference generated by the tube and the shell due to different wall temperatures, and reduces the axial load of the tube and the shell, thereby reducing the temperature difference stress of the tube, the tube plate and the shell and avoiding causing strength damage, instability damage and tube pull-out damage.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a pipeline compensator.
In order to achieve the above object, the present invention provides the following technical solutions.
The embodiment of the application discloses pipeline compensator sets up between two pipelines, including a bellows and be formed at the mounting flange at bellows both ends, the bellows axle center is formed with the cavity, two the pipeline is respectively certainly the cavity both ends are inserted to inside, the mounting flange inboard is formed with the first annular inclined plane of leanout, still includes a mounting flange and a trapezoidal seal circle, mounting flange one end inboard is formed and is leaned out and has the second annular inclined plane, first annular inclined plane and second annular inclined plane centre gripping simultaneously in trapezoidal seal circle both ends, and the extrusion trapezoidal seal circle makes its inner wall support hold in the outer wall of pipeline.
Preferably, in the pipe compensator, the width of the inner wall of the trapezoid sealing ring is larger than that of the outer wall of the trapezoid sealing ring.
Preferably, in the above pipe compensator, the mounting flange and the fixing flange are fixed by a plurality of bolts arranged in a circumferential direction.
Preferably, in the pipe compensator, a spacing space is formed between the mounting flange and the fixing flange.
Preferably, in the above pipe compensator, a compression spring is sleeved outside the bolt in the space.
Compared with the prior art, the utility model has the advantages of: can realize certain compensation through the bellows, the bellows both ends are passed through trapezoidal sealing washer and are realized sealed simultaneously, also can play the compensation to a certain extent, and this structure can realize the compensation in 3 positions promptly.

Detailed Description
The technical solutions in the embodiments of the present invention will be described in detail below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.
In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.
Referring to fig. 1, the pipe compensator 100 is disposed between two pipes 200, and includes a bellows 101 and mounting flanges 102 formed at two ends of the bellows 101, a cavity 103 is formed at an axis of the bellows 101, the two pipes 200 are inserted into the cavity 103 from two ends of the cavity 103, a first annular inclined surface 104 inclined outward is formed at an inner side of the mounting flange 102, and further includes a fixing flange 105 and a trapezoidal sealing ring 106, a second annular inclined surface 107 inclined outward is formed at an inner side of one end of the fixing flange 105, the first annular inclined surface 104 and the second annular inclined surface 107 are clamped at two ends of the trapezoidal sealing ring 106, and the trapezoidal sealing ring 106 is pressed to make an inner wall thereof abut against an outer wall of the pipe 200. The inner wall of the trapezoidal sealing ring 106 is wider than the outer wall thereof. The mounting flange 102 and the fixing flange 105 are fixed by a plurality of bolts 108 arranged in a circumferential direction. A spacing space 109 is formed between the mounting flange 102 and the fixing flange 105.
In this technical scheme, can realize certain compensatory action through the bellows, the bellows both ends are passed through the trapezoidal sealing washer and are realized sealed simultaneously, also can play compensatory action to a certain extent, and this structure can realize compensatory action in 3 positions promptly. During specific implementation, the fixing flange and the mounting flange are screwed up through the bolts, and the trapezoidal sealing ring is extruded in the screwing process, so that the trapezoidal sealing ring is tightly attached to the outer wall of the pipeline, and meanwhile, the two ends of the trapezoidal sealing ring are tightly attached to the inclined plane, and the sealing performance is ensured.
Further, a compression spring (not shown) is sleeved outside the bolt 108 in the space 109.
In the technical scheme, the stability of connection can be kept, and meanwhile, the connection can be removed, so that the influence is small.
It is noted that, herein, relational terms such as first and second, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Also, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising an … …" does not exclude the presence of other identical elements in a process, method, article, or apparatus that comprises the element.
The foregoing is directed to embodiments of the present application and it is noted that numerous modifications and adaptations may be made by those skilled in the art without departing from the principles of the present application and are intended to be within the scope of the present application.
