Abstract
The utility model discloses an axial corrugated pipe compensator with a strengthened connecting structure. The axial corrugated pipe compensator with the strengthened connecting structure consists of connecting pipes, a left lining pipe, a corrugated pipe, a diversion cylinder and a right lining pipe, wherein the two ends of the corrugated pipe are connected with the left lining pipe and the right lining pipe in a sealed way; the connecting pipes respectively sleeve the outer walls of the left lining pipe and the right lining pipe which are connected with the two ends of the corrugated pipe in the sealed way, wherein the flange ends of the connecting pipes are outward; stepped holes are formed in the inward openings of the connecting pipes and are in clearance fit with the outer walls of the straight side section of the corrugated pipe; the free ends of the left lining pipe and the right lining pipe are respectively connected with the inner walls of the matched connecting pipes in the sealed way so as to directly form the strengthened connecting structure that a welding seam around the straight side of the corrugated pipe is not folded. The diversion cylinder is lined in inner cavities of the left lining pipe and the corrugated pipe to form a protective guide structure of the corrugated pipe. According to the axial corrugated pipe compensator with the strengthened connecting structure, the aim of strengthening the welding seam at the straight side end of the corrugated pipe is fulfilled by the technical measures, and a compensation action is kept flexible.
Description
Technical field
The utility model relates to a kind of pipe safety device, and specifically, the utility model relates to a kind of axial corrugated expansion joint that is provided with strengthening linkage structure.
Background technique
Axially FlexbleJoint belongs to a kind of conventional pipeline compensator, and it is made up of adapter and the flange of the sealed at both ends connection of bellows.This type of compensator structure is very simple, making is easy, and price is cheap.Prior art products is conventionally supporting in low pressure heat-net-pipeline, can realize the expection of compensation or absorption end thrust and displacement.Although the axial FlexbleJoint of prior art is used widely in low pressure heat-net-pipeline,, the compensator bearing capacity of this structure is poor, the particularly weld seam rapid wear between bellows and adapter, its form of expression mainly contains weld cracking and produces leakage.
Model utility content
The utility model is the problem of weld seam rapid wear mainly for bellows straight flange in prior art products and between taking over, and proposes a kind of axial corrugated expansion joint that is provided with strengthening linkage structure, and this linkage structure is simple, reasonable stress, non-deformability are strong.
The utility model is achieved through the following technical solutions technical goal.
Be provided with the axial corrugated expansion joint of strengthening linkage structure, it by taking over, left bushing pipe, bellows, guide shell and right bushing pipe form.Described bellows two ends straight section is set on left bushing pipe and right bushing pipe outer wall, and the straight flange of ring bellows is along doing to be tightly connected between counterpart.Described adapter is the circular straighttube that one end is provided with flange, takes over and is set with outwardly on the left bushing pipe and right bushing pipe outer wall of the sealed at both ends connection of bellows with flange one end.Its improvements are: described adapter free end endoporus oral area is provided with step hole and bellows straight section outer wall Spielpassung, left bushing pipe and right bushing pipe free end are tightly connected with the nozzle inner wall coordinating respectively, directly form the strengthening linkage structure that ring bellows straight flange is not rolled over along weld seam.Described guide shell is the thin-wall circular tube of one end flange, guide shell liner is in left bushing pipe and bellows inner chamber, there is one end of flange to be positioned at left end and nozzle inner wall is tightly connected, the other end of inside stretching and right bushing pipe fit, the guide shell of liner forms the protection-guide structure to bellows.
The utility model compared with prior art, has following good effect:
1, the coaxial fit of multitube is simple in structure, making is easy;
2, the weld seam on ring bellows straight flange edge has bushing pipe to entrust, and only bears axial tension, not bearing radial force, thus be connected firmly, not easy to crack;
3, built-in guide shell has to bellows the effect of protecting and leading, and avoids deposit dirt in the trough of bellows, guarantees that bellows compensating movement is flexible, and reduces liquid resistance.
Brief description of the drawings
Fig. 1 is that the utility model structure is partly cutd open schematic diagram.
Fig. 2 is A place partial enlarged drawing in Fig. 1.
Embodiment
Below with reference to the accompanying drawings and in conjunction with the embodiments, the utility model is described in further detail.
The axial corrugated expansion joint that is provided with strengthening linkage structure shown in Fig. 1, it by taking over 1, left bushing pipe 2, bellows 3, guide shell 4 and right bushing pipe 5 form.Described bellows 3 two ends straight sections are set on left bushing pipe 2 and right bushing pipe 5 outer walls, and the straight flange of ring bellows 3 is along doing to be tightly connected between counterpart, and the parts of formation are built-in elastic bodies in the utility model, are directly used in and bear or compensating axial power and displacement.Described adapter 1 is provided with the circular straighttube of flange for one end, and it is outer connector, has again sheath effect.Taking over 1 is set with on the left bushing pipe 2 and right bushing pipe 5 outer walls of bellows 3 sealed at both ends connections outwardly with flange one end, endoporus oral area is inwardly provided with step hole and bellows 3 straight section outer wall Spielpassung, left bushing pipe 2 is connected with adapter 1 inner wall sealing coordinating respectively with right bushing pipe 5 free ends, directly forms the strengthening linkage structure of ring bellows 3 straight flanges along weld seam.This linkage structure accomplishes that weld seam herein only bears axial tension, and not bearing radial force, guarantees that weld seam is not rolled over, and in the utility model, the straight flange weld seam of bellows 3 is connected firmly thus, not easy to crack.Described guide shell 4 is the thin-wall circular tube of one end flanging, guide shell 4 liners are in left bushing pipe 2 and bellows 3 inner chambers, there is one end of flange to be positioned at left end and to take over 1 inner wall sealing and be connected, the other end of inside stretching and right bushing pipe 5 fits, the guide shell 4 of liner forms the protection-guide structure to bellows 3.Built-in guide shell is avoided deposit dirt in the trough of bellows 3, can guarantee that bellows 3 compensating movements are flexible, and reduces liquid resistance.
