The flexible compensator is simple in structure and flexible in compensation; most importantly, the home connecting pipe adopts a connector with the outer tapered pipe threads, so that the flexible compensator has convenience in installation and high sealing performance; the leakage probability of the connector is greatly reduced; the connector is small in size and has good coordination with indoor environment.
Description
Technical field
The utility model relates to a kind of safety installations of gas pipeline, and specifically, the utility model relates to a kind of supporting corrugated expansion joint in gas pipeline.
Background technique
Along with expanding economy, the progress of society, the newly-built building in city is more and more, and more and more higher, the gas pipeline supporting with building increases thereupon.Due to the infrastructure of different buildings and ground geological condition, there is some difference, and it is possible after building builds up, uneven settlement occurring.Ground trace sedimentation meeting causes the interface dislocation of air inlet gas pipeline and necessary structure, and Excessive Settlement the dislocation of house lead in gas pipeline even occurs and breaks to form leaking source.In engineering, conventionally adopt corrugated expansion joint to make up the alternate position spike that foundation settlement produces gas pipeline, the corrugated expansion joint of prior art has enough flexibilities, and due compensating action is played in displacement freely thereupon.But the bellows outer wall of prior art products is exposed, because thin-wall corrugated tube lacks protection, rapid wear.On the other hand, the interface of registering one's residence of prior art products adopts flanged connecting structure, although this kind of conventional linkage structure is simple, easy to connect, but it is large to take up room, and seems very inharmonious indoor, greatest problem is the anti-dislocation ability of this linkage structure, easily leaks, and has major safety risks.
Model utility content
The utility model, mainly for the deficiencies in the prior art, proposes a kind of flexible compensator of external sheath, and this is simple in structure, connects reliably, in effectively protecting bellows, does not reduce the flexibility of bellows.
The utility model is achieved through the following technical solutions technical goal.
Flexible compensator, it is made up of jointly externally connected pipe, sheath, flexible pipe, bundle choma cover, salient point and the adapter of registering one's residence.Described flexible pipe two ends coaxially connect respectively externally connected pipe and register one's residence and take over the flexible compensation mechanism of formation.Described externally connected pipe and the adapter of registering one's residence are round straight tube, and the free end of taking over of registering one's residence is wherein provided with outer cone pipe thread.Its improvements are, flexible pipe outer wall gap in flexible compensation mechanism is set with flexible sheath, the sheath two ends of the whole flexible pipe of the enclosure are fixedly connected with respectively bundle choma cover, the bundle choma cover that is positioned at two ends is nested with externally connected pipe and the adapter gap of registering one's residence respectively, take on outer tube wall with registering one's residence in externally connected pipe, at a distance of beam ring cover free end A=20～40mm ring circumference uniform distribution salient point formation axial limit structure.
Sheath in said structure and flexible pipe are cylindrical metal bellows.
As further improvement project, flexible pipe is the bellows that the common rolling of 2～4 layers of 0.2mm～0.4mm thin plate of a kind of use forms.
As further improvement project, sheath is a kind of bellows, forms ripple density ratio flexible pipe close 2%～15% under same length with 2～4 layers of 0.15mm～0.25mm thin plate rolling.
As further improvement project, the circular diameter being made up of salient point is greater than bundle choma cover free end internal diameter.
The utility model and prior art products comparison, have following good effect:
1, flexible compensation mechanism is placed in external sheath, simple in structure, makes easily;
2, in the time that dislocation distortion occurs in mounting point, under the protection of external sheath, alleviate the destruction to built-in flexible pipe, effectively improve compensator working life and Security;
3, the flexible pipe forming with the common rolling of multi-layered sheet is flexible better, and flexible compensating movement is sensitiveer;
4, register one's residence and take over employing circle outer cone pipe screw joint, be both convenient to install, also reduce the probability that connects few leakage, and joint volume is little, good with indoor environment harmony.
Brief description of the drawings
Fig. 1 is that the utility model structure is partly cutd open schematic diagram.
Embodiment
Below with reference to the accompanying drawings and in conjunction with the embodiments, the utility model is described in further detail.
Flexible compensator shown in the drawings is as the gas pipeline parts of registering one's residence, and its bore is DN50mm, and it is by externally connected pipe 1, sheath 2, flexible pipe 3, bundle choma cover 4, salient point 5 and register one's residence and take over 6 and jointly form.Described flexible pipe 3 is a kind of cylindrical metal bellowss, and in the present embodiment, with 4 layers of common rolling of 0.2mm thin plate, flexible pipe 3 two ends coaxially connect respectively externally connected pipe 1 and register one's residence and take over the flexible compensation mechanism of 6 formation.Described externally connected pipe 1 and the adapter 6 of registering one's residence are the supporting round straight tube of flexible pipe 3, and the free end of the adapter 6 of registering one's residence is wherein provided with outer cone pipe thread 6.1.Building gas pipe, service pipe, indoor pipe or gas-fired equipment are by the direct-connected flexible compensator of taper pipe thread, and because this joint tighness is good, firm, dislocation distortion can not be leaked, and in addition, taper pipe thread joint volume is little, and installation is rear and indoor environment harmony is good.In order to protect the flexible pipe 3 in flexible compensation mechanism not pressed without reason, the utility model is set with flexible sheath 2 in flexible pipe 3 outer wall gaps, the sheath 2 use individual layer 0.15mm thin plate rollings in the present embodiment, and under same length ripple density ratio flexible pipe 3 close 15%.Closeer because of ripple, sheath 2 is more soft than flexible pipe 3, adds and joins the flexibility that does not reduce flexible pipe 3 after sheath 2.Sheath 2 two ends of the whole flexible pipe 3 of the enclosure are fixedly connected with respectively bundle choma cover 4, the bundle choma cover 4 that is positioned at two ends is nested with externally connected pipe 1 and adapter 6 gaps of registering one's residence respectively, restraint choma apart and overlap 4 free ends outsides and be provided with salient point 5 as axial limit structure, the present embodiment bumps 5 is restrainted choma apart and is overlapped 4 free end A=20mm.In order to improve axial limiting quality, salient point 5 encircles externally connected pipe 1, adapter 6 outer walls of registering one's residence are uniform, is greater than bundle choma overlaps 4 free end internal diameters by the circular diameter that on same circumference, uniform salient point 5 forms.
Flexible compensation mechanism is placed in sheath by the utility model, simple in structure, both protected flexible pipe 3, also do not reduce its flexibility, guarantees that flexible compensating movement is sensitiveer.The most important thing is to register one's residence and take over 6 employing outer cone pipe screw joints 6.1, it is convenient to install, and good airproof performance greatly reduce joint and leak probability, and joint volume is little, good with indoor environment harmony.
