Description
Technical field
The utility model relates to a kind of pipe safety device, and specifically, the utility model 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 crisscross pipe network operation process.Pipe deforming performance pattern is mainly to have destructive end thrust and displacement.For the safety of pipe network, the equipped pipeline compensator at pipeline related node place usually in engineering, applying maximum is corrugated expansion joint, utilizes its flexible structure to absorb or compensates ducted end thrust and displacement.Traditional bellows collocation structure is simple, and compensating movement is flexible, can meet the ancillary engineering facility requirement.But the corrugated expansion joint of prior art is multi-section structure, axial length is partially long, poor stability, and the corrugated expansion joint of installing at Nodes occupies larger space, naturally strengthens the size of support, increases user's economic burden.
The model utility content
The problem that the utility model is oversize mainly for the prior art axial dimension, the straight pipe external balance type bellows compensator of propose a kind of foot simple in structure, flexible, compensate flexibly, axial dimension is short and Safety performance is good.
The utility model 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 forms two measure-alike small corrugated pipes and take the interlock collocation structure that outer wall of inner tube is 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 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 outer tube dislocation connects and composes take the link balance structure that large bellows is elastic element.
In 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 utility model 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, form skin and be the protective layer structure of internal layer, 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.
The accompanying drawing explanation
Fig. 1 is the utility model structural profile schematic diagram.
Embodiment
Below the utility model is described in further detail with reference to the accompanying drawings.
Straight pipe external balance type bellows compensator shown in Fig. 1, be a kind of compensator of shrink-fit structure, and structure comprises inner tube 1, outer tube 2, large bellows 3, take over 4, jacket pipe 5, honeycomb duct 6 and small corrugated pipe 7.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 enclosure left sides, 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 forms two measure-alike small corrugated pipes 7 and take the interlock collocation structure that inner tube 1 outer wall is axle.Described large bellows 3 is 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 right side, also plays differential connection function.The concrete linkage structure of outer tube 2 is inner tube 1 outer wall 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 connects and composes take the equilibrium structure that large bellows 3 is elastic element.
In order to improve the small corrugated pipe 7 and the small corrugated pipe 7 environment difference of living in that is in jacket pipe 5 right sides in jacket pipe 5 inner chambers, be provided with through hole 5.1 and link up outer tube 2 inner chambers on jacket pipe 5 walls.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 on outer tube 2 walls, for draining air or the hydrops of outer tube 2 inner chambers.
The utility model is arranged in pipe network, when the inner tube 1 in left side is born axial force to the right or displacement, the inner tube 1 on right side is motionless, the inner tube 1 in left side drives two small corrugated pipes 7 and synchronously moves to right together with outer tube 2, make the axial tension compensating movement, large bellows 3 is done the axial compression motion, plays balanced action.When if the inner tube in left side 1 is born axial force left or displacement, the inner tube 1 on right side is still motionless, and the inner tube 1 in left side drives two small corrugated pipes 7 and synchronously moves to left together with outer tube 2, makes the axial compression compensating movement, large bellows 3 is done the axial tension motion, still plays balanced action.In like manner, when the inner tube 1 on right side is born the axial force of different direction or displacement, other each part produces corresponding actions, and each part interaction relation sees the following form:
In sum, the utility model 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 feature, and the balanced action by large bellows 3 directly improves Safety performance.
