Description
Technical field:
The utility model relates to expansion joint technical field, is specifically related to a kind of desulfurization freedom from repairs non-metal expansion joint.
Background technique:
Expansion joint is the additional stress for compensating because temperature difference and mechanical vibration cause, and is arranged on a kind of flexible structure on container shell or pipeline.Due to it as a kind of can the elastic compensation element of free-extension, there is the advantages such as reliable operation, functional, compact structure, be widely used in the departments such as chemical industry, metallurgy, nuclear energy.
Expansion joint is also compensator traditionally, or slip joint.By forming the bellows (a kind of elastic element) of its operative body and holding the annexes such as pipe, support, flange, conduit to form.Expansion joint is the additional stress in order to compensate because temperature difference and mechanical vibration cause, and is arranged on a kind of flexible structure on container shell or pipeline.Utilize effective dilatation of its operative body bellows, to absorb pipeline, conduit, container etc. by reason and the dimensional changes produced such as expanding with heat and contract with cold, or axial, the transverse direction of compensation pipes, conduit, container etc. and angular displacement.Also can be used in noise-and-vibration-reduction, heat supply, when heating up to prevent heat supply pipeline, pipe deforming or destruction is caused due to thermal stretching or temperature stress, need to arrange compensator on pipeline, to compensate the thermal stretching of pipeline, thus the stress reducing tube wall and the active force acted on valve member or supporting structure.
Due to expansion joint as a kind of can the elastic compensation element of free-extension, there is the advantages such as reliable operation, functional, compact structure, be widely used in the departments such as chemical industry, metallurgy, nuclear energy.The expansion joint that container adopts, has various ways, with regard to the shape of ripple, applies the most extensive with U-shaped expansion joint, secondly also has Ω shape and C shape etc.And the expansion joint adopted on pipeline is with regard to structure compensation, be divided into again universal, pressure balance type, hinge type and Universal connector hair style etc.
Existing non-metal expansion joint is inconvenient in use, and needs often maintenance, loses time, inconvenient operation.
Model utility content:
The purpose of this utility model is defect for prior art and deficiency, provides a kind of desulfurization freedom from repairs non-metal expansion joint that a kind of structure is simple, reasonable in design, easy to use.
In order to solve the problem existing for background technique, a kind of desulfurization freedom from repairs non-metal expansion joint of the present utility model, it comprises connecting plate, nonmetal composite bed, damping spring, guide plate, wear-resisting buffer projection, resistance to compression ball; Between two connecting plates, nonmetal composite bed is installed, the inside of nonmetal composite bed is provided with damping spring, the upper end of damping spring is provided with guide plate, guide plate is provided with wearing layer, the middle part of wearing layer is provided with wear-resisting buffer projection, several resistance to compression ball is separately positioned between nonmetal composite bed and guide plate, and the outer surface of resistance to compression ball is provided with glass fibre layer.
As preferably, described guide plate is corrugated sheet.
As preferably, described nonmetal composite bed is the nonmetal composite bed of thread type.
After adopting said structure, the utility model beneficial effect is: realize freedom from repairs, long service life, is convenient to realize guiding, easy and simple to handle, easy to use.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
Description of reference numerals:
1-connecting plate; The nonmetal composite bed of 2-; 3-damping spring; 4-guide plate; 5-wear-resisting buffer is protruding; 6-resistance to compression ball.
Embodiment:
Below in conjunction with accompanying drawing, the utility model is further described.
In order to make the purpose of this utility model, technological scheme and advantage clearly understand, below in conjunction with the drawings and the specific embodiments, the utility model is further elaborated.Should be appreciated that embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 1, this embodiment adopts following technological scheme: it comprises connecting plate 1, nonmetal composite bed 2, damping spring 3, guide plate 4, wear-resisting buffer projection 5, resistance to compression ball 6; Between two connecting plates 1, nonmetal composite bed 2 is installed, the inside of nonmetal composite bed 2 is provided with damping spring 3, the upper end of damping spring 3 is provided with guide plate 4, guide plate 4 is provided with wearing layer, the middle part of wearing layer is provided with wear-resisting buffer projection 5, several resistance to compression ball 6 is separately positioned between nonmetal composite bed 2 and guide plate 4, and the outer surface of resistance to compression ball 6 is provided with glass fibre layer.
Further, described guide plate 4 is corrugated sheet.
Further, described nonmetal composite bed 2 is the nonmetal composite bed of thread type.
The working principle of this embodiment is: adopt wear-resisting buffer protruding 5 to realize buffering, wear-resisting, do not need repairing, adopt guide plate 4 to realize guiding simultaneously, save time, easy and simple to handle, and can realize damping and resistance to compression, increases the service life.
The above, only in order to the technical solution of the utility model to be described and unrestricted, other amendment that those of ordinary skill in the art make the technical solution of the utility model or equivalently to replace, only otherwise depart from the spirit and scope of technical solutions of the utility model, all should be encompassed in the middle of right of the present utility model.
