The corrugated pipe expansion joint with the variable ratio balancing device comprises a pipeline I (2), a pipeline II (13), a working corrugated pipe (4), a balancing corrugated pipe (10) and a pressure thrust mechanism. The pipeline II (13) is communicated with one end of the balancing corrugated pipe (10), and the other end of the balancing corrugated pipe (10) is sealed through a blanking plate; the pressure thrust mechanism comprises a hinge plate I (5), a junction plate (6), a base plate (8) and a hinge plate II (14); the pipeline I (2) is connected with one end of the hinge plate I (5), and the other end of the hinge plate I (5) is connected with the end portion of the balancing corrugated pipe (10) through the junction plate (6) and the hinge plate II (14). Pressure thrust generated from the working corrugated pipe can be balanced under the condition of small size of the balancing corrugated pipe, so that the device is prevented from bearing pressure thrust of the working corrugated pipe.
Description
Technical field
The utility model belongs to the expansion joint technical field, is specifically related to a kind of bellows expansion joint with control with changed scale Equilibrator.
Background technique
Metal corrugated pipe expansion joint is that be heated in modern times pipe network and equipment carries out one of critical component of thermal compensation, has the effect of bit shift compensation, vibration and noise reducing and sealing.Be widely used at present on the equipment such as heating pipeline, craft piping, machine, pump and pressurized container of each industrial department such as metallurgy, oil refining, petrochemical industry, electric power (thermoelectricity, water power and nuclear power), heat supply network, boats and ships, building, cement, aerospace and machinery.But because the structural feature of bellows itself, bellows can produce pressure thrust to the two ends at coupled place, further can act on the equipment with its connecting end, can damage equipment in the time of seriously, causes serious consequence.
Fig. 1 saves in the pipeline schematic representation that has equipment and fixed bearing for bellows expansion in the prior art, and work bellows 4 is set between equipment 9 and the fixed bearing 1, and the bellows 4 of working is used for the axial thermal walking between canceller 9 and the fixed bearing 1; One end of work bellows 4 links to each other with equipment 4 by pipeline I 2, and the other end links to each other with fixed bearing 1 with pipeline II 13.When in pipeline I 2 and the pipeline II 13 pressure being arranged, fixed bearing 1 is in order to bearing the pressure thrust of work bellows 4, and can act on the equipment 9 with the pressure thrust of equipment 9 connecting ends.
The model utility content
For solving the problems of the technologies described above, the purpose of this utility model is to propose a kind of bellows expansion joint with control with changed scale Equilibrator.
The utility model adopts following technological scheme for finishing above-mentioned purpose:
A kind of bellows expansion joint with control with changed scale Equilibrator, described bellows expansion joint include pipeline I, pipeline II and work bellows; One end of described work bellows is connected with the pipeline I, and the other end is connected with the pipeline II; Described bellows expansion joint also includes the balance bellows and equipment is produced the pressure thrust mechanism of pressure thrust in order to balance work bellows; One end of described balance bellows is communicated with the pipeline II, and the other end of balance bellows seals by shrouding; Described pressure thrust mechanism includes hinge plate I, connecting plate, seat board and hinge plate II; One end of described hinge plate I is connected with the pipeline I by the link I, and an end of the other end of hinge plate I and connecting plate is hinged; Described connecting plate is hinged with the seat board that is fixed on the pipeline II, and the other end hinge plate II of described connecting plate is hinged; The other end of described hinge plate II is connected with the end of balance bellows by the link II; Described link is between balance bellows and shrouding.
A kind of bellows expansion joint that the utility model proposes with control with changed scale Equilibrator, one balance bellows is set on expansion joint, the balance bellows is connected with the work bellows, when pipeline internal medium has pressure, the work bellows produces different big or small pressure thrusts separately simultaneously with the balance bellows, and wherein the pressure thrust of bellows is that bellows useful area Ae and pipeline internal medium pressure P are long-pending.Pressure thrust mechanism is set on pipeline, utilize the mechanics lever principle, by changing the ratio value of lever two ends brachium, can make operating wave line pipe in that the pressure thrust that can balance work bellows be produced is just arranged under the situation of reduced size, avoid making equipment to bear the pressure thrust of work bellows.
Description of drawings
Fig. 1 is used for fixing bellows expansion joint schematic representation between bearing and the equipment for prior art.
Fig. 2 is applied to structural representation between fixed bearing and the equipment for the utility model.
Among the figure: 1, fixed bearing, 2, the pipeline I, 3, the link I, 4, the work bellows, 5, the hinge plate I, 6, connecting plate, 7, bearing pin, 8, seat board, 9, equipment, 10, the balance bellows, 11, link II, 12, shrouding, 13, the pipeline II, 14, the hinge plate II.
Embodiment
With specific embodiment the utility model is illustrated in conjunction with the accompanying drawings, still, the utility model is not limited to these embodiments, and what can be used for also that other has a same operating conditions has a bellows expansion joint pipeline.
As shown in Figure 2, a kind of bellows expansion joint with control with changed scale Equilibrator, described bellows expansion joint include pipeline I 2, pipeline II 13 and work bellows 4; One end of described work bellows 4 is connected with pipeline I 2, and the other end is connected with pipeline II 13; Described bellows expansion joint also includes balance bellows 10 and equipment is produced the pressure thrust mechanism of pressure thrust in order to balance work bellows; One end of described balance bellows 10 is communicated with pipeline II 13, and the other end of balance bellows 10 is by shrouding 12 sealings; Described pressure thrust mechanism includes hinge plate I 5, connecting plate 6, seat board 8 and hinge plate II 14; One end of described hinge plate I 5 is connected with pipeline I 2 by link I 3, and an end of the other end of hinge plate I 5 and connecting plate 6 is hinged; Described connecting plate 6 is hinged with the seat board 8 that is fixed on the pipeline II 9, and the other end of described connecting plate 6 and hinge plate II 14 are hinged; The other end of described hinge plate II 14 is connected with the end of balance bellows 10 by link II 11; Described link II 11 is between balance bellows 10 and shrouding 12.
When in the pipeline pressure P being arranged, the pressure thrust that 4 pairs of equipment of work bellows 1 produce is F1=PAe1, and the pressure thrust that balance bellows 10 produces is F2=PAe2, and F1 is identical with the F2 direction.By changing L1 and the ratio value of L2 and the size of balance bellows 10 on the linkage, utilize the mechanics lever principle when F1L1=F2L2, the pressure thrust that the balance bellows can balance work bellows produces equipment, L2 and L1 ratio are big more, and the size of balance bellows will be more little.When in the pipeline temperature being arranged, the work bellows can absorb the thermal stretching amount of pipeline between work bellows and the equipment in addition.Can realize work bellows expansion nodal axisn like this to compensation ability, can guarantee again pressure thrust that the work bellows produces do not act on its connection device on, thereby the Security that improves equipment.
