Abstract
The utility model discloses a high-temperature floating ring angular expansion joint which is applicable to a non-heat-insulation high-temperature pipeline, and comprises a bellows (1) and cylinder joints (2) connected at two ends of the bellows. The high-temperature floating ring angular expansion joint is characterized in that the outer walls of the cylinder joints (2) are fixedly provided with outer side limiting blocks (6) and inner side limiting blocks (7); the inner sides of the two outer side limiting blocks (6) and the outer sides of the inner side limiting blocks (7) are respectively provided with outer side ring plates (9) and inner side ring plates (11) which are fixed and connected with each other by floating connecting pipes (10), and floating ring components are formed by the outer side ring plates, the inner side ring plates and the floating connecting pipes; and the floating components at the two ends of the bellows (1) are respectively fixed with hinge components (4 and 5) which are connected with each other by a pin shaft (3). The high-temperature floating ring angular expansion joint is simple and practical, reduces the thermal stress caused by the temperature to the utmost extent at high temperature under the condition of meeting bearing force, avoids structural components having excessive deformation and cracking, ensures the bellows not to lose stability and can work normally.
Description
Technical field
The utility model relates to a kind of expansion joint, is adapted to not have the thermal insulation high-temperature pipe.
Background technique
Design at no thermal insulation high-temperature pipe application angle expansion joint is directly to weld load-carrying construction on pipeline at present, is the strength and stiffness that increase load spare, usually adopts the dual collar plate gang welding to become.On the pipeline directly the expansion joint of welding load-carrying construction during at high temperature because the existence of temperature gradient, to produce excessive thermal stress in the welding part, cause the shell ring of welding part that local deformation when serious (even can cause local cracking) is taken place, the load spare that is attached thereto also deforms accordingly, the bellows that also just causes simultaneously being attached thereto produces unstability, makes the expansion joint cisco unity malfunction.
Summary of the invention
The purpose of this utility model is exactly the above-mentioned deficiency at prior art, provide a kind of can the elimination fully to reach the negative effect of bringing other thus, thereby guarantee the high temperature floating ring angle expansion joint of expansion joint proper functioning at high temperature because high temperature produces excessive thermal stress in the welding part.
The technical solution adopted in the utility model is as follows:
A kind of high temperature floating ring angle expansion joint, include bellows and be connected the shell ring at its two ends, it is characterized in that on the shell ring outer wall at bellows two ends, all being installed with outside limiting stopper and inner side limiting-position piece, the outside of the inboard of two outside limiting stoppers and inner side limiting-position piece is separately installed with outside ring flat-plate and inboard ring flat-plate, between the outside ring flat-plate and the inboard ring flat-plate by affixed connection of unsteady adapter, their threes form the floating ring assembly, be fixed with two hinge components on the unsteady assembly at above-mentioned bellows two ends respectively, connect by bearing pin between two hinge components.
Describedly be installed on the outside limiting stopper or the inner side limiting-position piece last antitorque and be fixed on two of floating ring assembly between antitorque.
The beneficial effects of the utility model have:
Simple and practical, under high temperature condition, can reduce the thermal stress that temperature causes under the condition of load to greatest extent satisfying, avoid structural member excessive deformation even cracking, make the bellows can unstability, energy-conservation proper functioning expands.
Description of drawings
Fig. 1 is the structural representation of facing of the present utility model.
Fig. 2 is a side-looking structural representation of the present utility model.
Embodiment
The utility model is further described below in conjunction with accompanying drawing:
As shown in Figure 1, 2, the utility model includes the two ends that bellows 1 and two shell ring 2, two shell rings 2 are installed in bellows 1 respectively, has all welded outside limiting stopper 6 and inner side limiting-position piece 7 on two shell ring 2 outer walls.The outside of inboard of limiting stopper 6, the outside and inner side limiting-position piece 7 is separately installed with outside ring flat-plate 9 and inboard ring flat-plate 11, being welded with the adapter 10 of floating between outside ring flat-plate 9 and the inboard ring flat-plate 11, and their threes form the floating ring assembly.Also be welded with hinge component 4,5 on the unsteady assembly at bellows 1 two ends respectively, connect by bearing pin 3 between the hinge component 4,5.And being installed on the outside limiting stopper 6 or the inner side limiting-position piece 7 last antitorque 8 is being fixed on two of floating ring assembly between antitorque 12.
The blind plate power of the utility model expansion joint is delivered to the floating ring assembly by outside limiting stopper 6 or inner side limiting-position piece 7, thereby is delivered to hinge component 4 and hinge component 5, is born by bearing pin 3 at last.Last antitorque 12 links to each other with the floating ring structure, links to each other with outside limiting stopper 6, inner side limiting-position piece 7 for antitorque 8 down, and antitorque up and down is combined into antitorque structure and prevents the load-carrying construction rotation.Adapter 10 directly leaves sufficient shell ring clearance for expansion and outside limiting stopper 6 or inner side limiting-position piece 7 with shell ring 2 and all allows free expansion owing to float, total when high temperature because the stress drop that causes of temperature is low to moderate bottom line, avoid structural member abnormal deformation even destruction when high temperature, guaranteed the normal operation of expansion joint.
Other undeclared part of the utility model is same as the prior art.
Claims (2)
1. high temperature floating ring angle expansion joint, include bellows (1) and be connected the shell ring (2) at its two ends, it is characterized in that on shell ring (2) outer wall at bellows (1) two ends, all being installed with outside limiting stopper (6) and inner side limiting-position piece (7), the outside of the inboard of two outside limiting stoppers (6) and inner side limiting-position piece (7) is separately installed with outside ring flat-plate (9) and inboard ring flat-plate (11), (10) are affixed is connected by unsteady adapter between outside ring flat-plate (9) and the inboard ring flat-plate (11), their threes form the floating ring assembly, be fixed with hinge component (4 respectively on the unsteady assembly at above-mentioned bellows (1) two ends, 5), connect by bearing pin (3) between the hinge component (4,5).
