Description
Technical field
The present invention relates to a kind of pipe safety device, specifically, the present invention relates to a kind of straight pipe external balance type corrugated expansion joint.
Background technique
Industry heat distribution pipe network and urban heating network framework scope are wide, and pipeline is long.Because of built-in medium temperature, pressure or variation of ambient temperature, produce thus corresponding distortion in the crisscross pipe network operation process.Pipe deforming performance pattern mainly is to have destructive end thrust and displacement.For the safety of pipe network, the common equipped pipeline compensator at pipeline related node place in the engineering, using maximum is corrugated expansion joint, utilizes its flexible structure absorption or compensates ducted end thrust and displacement.Traditional bellows collocation structure is simple, and compensating movement is flexible, can satisfy the ancillary engineering facility requirement.But the corrugated expansion joint of prior art is multi-section structure, and axial length is partially long, poor stability, and the corrugated expansion joint of installing at Nodes occupies than large space, naturally strengthens the size of support, increases user's economic burden.
Summary of the invention
The present invention proposes a kind of foot simple in structure, flexible, compensates the straight pipe external balance type bellows compensator flexible, that axial dimension is short and Safety performance is good mainly for the oversize problem of prior art axial dimension.
The present invention is achieved through the following technical solutions technical goal.
The straight pipe external balance type bellows compensator, it comprises inner tube, outer tube, large bellows, adapter, jacket pipe, honeycomb duct and small corrugated pipe.Described inner tube is the straight-through tube that is provided with outward flange, and two inner tubes are arranged with the relative coaxial spaced of an end that flange is arranged, and alternate place inner tubal wall is lined with honeycomb duct, and outer wall of inner tube is set with small corrugated pipe, and small corrugated pipe is fixedly connected with the flange of inner tube by taking over.The small corrugated pipe in described jacket pipe enclosure left side, left end is fixedly connected with the small corrugated pipe in left side by adapter, right-hand member is fixedly connected with the flange of right side inner tube, and the jacket pipe that dislocation connects consists of the interlock collocation structure of two measure-alike small corrugated pipes take outer wall of inner tube as axle.Its improvements are: described large bellows cover cover jacket pipe, right-hand member is fixedly connected with jacket pipe by taking over.Described outer tube is coaxial binodal shell, the direct large bellows of the enclosure and the small corrugated pipe that is positioned at the right side, the outer wall of inner tube in larger diameter end and left side is tightly connected, the outer wall of inner tube Spielpassung on smaller diameter end and right side, the small corrugated pipe on right side is fixedly connected with outer tube by adapter, and the outer tube dislocation connects and composes the link balance structure take large bellows as elastic element.
In the said structure, the chuck tube wall is provided with through hole and links up outer tube bore, and the outer tube wall bottom is provided with petcock.
The present invention compared with prior art has following good effect:
1, the coaxial fit of multilayer is simple in structure, makes easily;
2, the coaxial fit of multilayer consists of skin and is the protective layer structure of internal layer, and is safe;
3, the coaxial fit of multilayer, axial dimension is short, is conducive to reduce stent size, saves and builds cost;
4, outside under the pressure balanced condition, the bidirectional compensating ability is consistent, and compensation flexibly.
Description of drawings
Fig. 1 is structural profile schematic diagram of the present invention.
Embodiment
The invention will be further described with reference to the accompanying drawings for the below.
Straight pipe external balance type bellows compensator shown in Figure 1 is a kind of compensator of shrink-fit structure, comprises inner tube 1, outer tube 2, large bellows 3, adapter 4, jacket pipe 5, honeycomb duct 6 and small corrugated pipe 7 in the structure.Described inner tube 1 is for being provided with the straight-through tube of outward flange, and two inner tubes 1 are spaced with relatively same of the end that flange is arranged, and alternate place inner tubal wall is lined with honeycomb duct 6.Inner tube 1 outer wall is set with small corrugated pipe 7, and small corrugated pipe 7 is fixedly connected with the flange of inner tube 1 by taking over 4.The small corrugated pipe 7 in described jacket pipe 5 enclosures left side, left end by take over 4 be fixedly connected with the left side small corrugated pipe 7, right-hand member is fixedly connected with the flange of right side inner tube 1, and the jacket pipe 5 that dislocation connects consists of the interlock collocation structure of two measure-alike small corrugated pipes 7 take inner tube 1 outer wall as axle.Described large bellows 3 is used for balance, its enclosure jacket pipe 5, and right-hand member is fixedly connected with jacket pipe 5 by taking over 4.Described outer tube 2 is coaxial binodal shell, is the outer casing of compensator, except playing the large bellows 3 of the enclosure and the small corrugated pipe 7 that is positioned at the right side, also plays differential connection function.Outer tube 2 concrete linkage structures are inner tube 1 outer walls on the left of larger diameter end is tightly connected, the inner tube 1 outer wall Spielpassung on smaller diameter end and right side, and the small corrugated pipe 7 on right side is fixedly connected with outer tube 2 by taking over 4.Outer tube 2 dislocation connect and compose the equilibrium structure take large bellows 3 as elastic element.
In order to improve the small corrugated pipe 7 and the small corrugated pipe 7 environment difference of living in that are in jacket pipe 5 right sides in jacket pipe 5 inner chambers, be provided with through hole 5.1 at jacket pipe 5 walls and link up outer tube 2 inner chambers.Relatively airtight because of outer tube 2 inner chambers, in order to improve the flexibility of large bellows 3 actions, be provided with petcock 2.1 at outer tube 2 walls, be used for draining air or the hydrops of outer tube 2 inner chambers.
The present invention is installed in the pipe network, when the inner tube 1 in left side bear to the right axial force or during displacement, the inner tube 1 on right side is motionless, the inner tube 1 in left side and outer tube 2 drive together two small corrugated pipes 7 and move to right synchronously, make the axial tension compensating movement, large bellows 3 is then done the axial compression motion, plays balanced action.If the inner tube in left side 1 bear left axial force or during displacement, the inner tube 1 on right side is still motionless, and the inner tube 1 in left side and outer tube 2 drive together two small corrugated pipes 7 and move to left synchronously, make the axial compression compensating movement, large bellows 3 is then done the axial tension motion, still plays balanced action.In like manner, when the inner tube 1 on right side was born the axial force of different direction or displacement, other each part then produced corresponding actions, and each part interaction relation sees the following form:
In sum, the present invention adopts the multilayer shrink-fit structure, greatly shortens axial dimension, reduces the support equipped size, the most important thing is keeping nose balance flexibly outside the feature, and the balanced action by large bellows 3 directly improves Safety performance.
