Abstract

The invention discloses a mesh-belt type bidirectional pipeline compensator, which comprises frames, bolt assemblies, a heat insulation lining, an outer pipe and an inner pipe, wherein the outer pipe and the inner pipe are both flexible bodies and are arranged in an outwards convex manner. The frames are shaped as circular discs, the axial section of each frame is of an inequilateral rectangular groove, the annular narrow edges of the frames are uniformly provided with through holes and the bolt assemblies, and the two frames are oppositely and vertically arranged along the outer plane of the groove bottom. The outer pipe is a rubber member, wherein two ends of the outer pipe are respectively overlapped to the narrow edges of the frames and are locked and connected by the bolt assemblies to form an inner cavity, and the heat insulation lining is filled in the inner cavity. Two ends of the inner pipe are respectively in sealed connection with the inner wall of the wider edges of the frames to form an internal heat insulation compensation structure which consists of the inner pipe, the heat insulation lining and the outer pipe and has no limitation to the flow direction of a medium. The mesh-belt type bidirectional pipeline compensator disclosed by the invention is large in compensation dosage, flexible in action and good in heat insulation effect. Most importantly, the inner pipe is used for directly blocking the heat insulation lining, and therefore no dropping problem is caused to the heat insulation lining; and meanwhile, the mesh-belt type bidirectional pipeline compensator also has the advantages of solving the problem that the flow direction of the medium is limited and greatly prolonging the service life.

Description

The mesh belt type Double-way pipe compensator

Technical field

The present invention relates to a kind of pipe safety device, specifically, the present invention relates to a kind of pipeline compensator.

Background technique

The pipeline work temperature difference of power plant's smoke exhaust is larger, and the physical deformation amount fluctuation that produces at random is also large, and the internal stress that frequent deformation is brought is pipe safety hidden danger.In the engineering usually in-line arrangement fume pipe serial connection compensator absorb or compensate internal stress.Because the power-plant flue gas discharge capacity is large, supporting pipeline is also corresponding thick, and the compensation ability of heavy caliber compensator is had higher requirement.Generally use non-metal compensator in the existing engineering, such compensator major character is to make compensating element with nonmetallic material, for fear of the medium contact compensating element, at inner chamber the rigidity inner tube is set.Inner tube is the reducer structure, enlarged diameter section is fixedly connected on the inner tube entrance point, minor diameter is suspended in the inner tube outlet end, although this kind cantilever-type sleeve pipe is simple in structure and do not limit radial and axial compensating movement, but the reducer reduced diameter section directly reduces the compensator cross-sectional flow area, also only allows medium to flow towards a direction simultaneously.

Summary of the invention

The present invention is mainly for the deficiencies in the prior art, proposes a kind of medium and compensating element interface and distinguishes, seals reliable, high insulating effect, long service life, MEDIA FLOW to the mesh belt type Double-way pipe compensator of not limitting, compensate or absorb flexible movements.

The present invention is achieved through the following technical solutions technical goal.

The mesh belt type Double-way pipe compensator, it comprises skeleton, bolt assembly, insulating lining, outer tube and inner tube.Described outer tube and inner tube are flexible body, are outer gibbosity and install; Described skeleton is discoid, and axial cross section is the inequilateral rectangle groove, encircles narrow limit uniform through hole construction bolt assembly, relative thirty years of age with the bottom land outerplanar on two skeletons.Described outer tube is the rubber mass member, and two ends are overlapped on respectively on the narrow limit of skeleton and with bolt assembly locking and connect, and load insulating lining in the inner chamber that forms.Its improvements are: described inner tube two ends are connected with the broadside inner wall sealing of skeleton respectively, consist of with inner tube, insulating lining and outer tube to form MEDIA FLOW to the interior insulation collocation structure of not limitting.

Flexible inner tube is that a kind of the braiding with stainless steel strip forms in the said structure.

The present invention compared with prior art has following good effect:

1, the inner tube two ends skeleton that is tightly connected does not respectively change the compensator latus rectum, does not reduce flow efficiency, the most important thing is that MEDIA FLOW is to not limitting;

2, the flexible compensation structure that is formed by inner tube, insulating lining and outer tube, the compensation surplus is large, and resistance is little;

3, inner tube block insulating lining, insulating lining be without the problem of dropping, good heat-insulation effect and stable.

Embodiment

The below with reference to the accompanying drawings and in conjunction with the embodiments, the invention will be further described.

Mesh belt type Double-way pipe compensator shown in Figure 1, it comprises skeleton 1, bolt assembly 2, insulating lining 3, outer tube 4 and inner tube 5.Described outer tube 4 and inner tube 5 are flexible body, are outer gibbosity and install.Described skeleton 1 is discoid, and axial cross section is the inequilateral rectangle groove, encircles narrow limit 2, two skeletons 1 of uniform through hole construction bolt assembly with the bottom land outerplanar relative thirty years of age.Described outer tube 4 is the rubber mass member, and two ends are overlapped on respectively on the skeleton 1 narrow limit and with bolt assembly 2 lockings and connect, and load insulating lining 3 in the inner chamber that forms.Inner tube 5 is the stainless steel strip braided fabric, and two ends are connected with the broadside inner wall sealing of skeleton 1 respectively, and inner tube 5 has compensation or absorption function simultaneously except the effect of playing block insulating lining 3.This structure does not change the compensator latus rectum, does not reduce flow efficiency.The interior insulation collocation structure that the present invention is comprised of inner tube 5, insulating lining 3 and the outer tube 4 of flexibility, compensation rate is large, flexible movements, in the insulation situation, both can make respectively radial compensation and nose balance, also can move simultaneously, most important is inner tube 5 direct block insulating linings 3, insulating lining 3 problem that do not drop has also solved the problem of MEDIA FLOW to restriction simultaneously, greatly improves working life.
