Description
Technical field
The present invention relates to a kind of corrugated expansion joint, it comprises balance bellows, and be connected to the first bellows and second bellows at balance bellows two ends, first bellows and the second bellows are connected on heat distribution pipeline respectively by the first adapter and the second adapter, and the line compensating heat distribution pipeline expands.
Background technique
Heat distribution pipeline can produce line and expand or linear shrinkage because expanding with heat and contract with cold, have influence on the safe operation of heat distribution pipeline, usually uses corrugated expansion joint to compensate expanding with heat and contract with cold of heat distribution pipeline.For making corrugated expansion joint have enough extending amounts, multiple bellows is adopted to link together.Its deficiency is: flowing medium can produce larger pressure thrust at bellows, easily produces harmful effect to the equipment be connected or pipeline pipe support; The effect of FlexbleJoint deadweight simultaneously, easily makes bellows be out of shape and unstability.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of corrugated expansion joint, and the thrust caused to make fluid medium pressure is balanced, and does not act on or seldom act on connected equipment.
This corrugated expansion joint comprises balance bellows 5, the first bellows 3 and the second bellows 7 is welded with respectively by middle joint 51 at the two ends of balance bellows, the caliber of the first bellows is equal with the caliber of the second bellows, first bellows left end is welded with left joint 31, left joint one end is welded with the first adapter 1, the right-hand member of the second bellows is welded with right connector 71, right connector one end is welded with the second adapter 8, gap under the effect of axial force between the first adapter 1 and the second adapter 8 end face in opposite directions changes thereupon, it is characterized in that, the middle joint 51 at the two ends of balance bellows is welded with left end ring 21 respectively, right-hand member ring 22, left joint 31 is welded with the first otic placode 2, right connector 71 is welded with the second otic placode 23, many first pull bars 4 are provided with symmetrically between first otic placode 2 and right-hand member ring 22, many second pull bars 41 are provided with symmetrically between second otic placode 23 and left end ring 21, the caliber of described balance bellows is greater than the caliber of the first bellows.
Improve as one, the first described adapter 1 extends to the middle part of right connector to the right, and the tube wall that the first adapter is positioned at the first bellows, the second bellows and balance bellows is provided with through hole 6.
The feature of this corrugated expansion joint is, the caliber of balance bellows is greater than the caliber of the first bellows, the second bellows, the thrust that hydrodynamic pressure produces in balance bellows is greater than the thrust in the first bellows, the second bellows, under the effect of hydrodynamic pressure, balance bellows extend vertically, and the first bellows, the second bellows are compressed, the thrust that compared with prior art this corrugated expansion joint can make hydrodynamic pressure cause is balanced, and the equipment that can not be connected to compensator produces harmful effect; First adapter extends to the middle part of right connector to the right, can support the deadweight of FlexbleJoint, avoid bellows deformation instability.

Accompanying drawing mark represents respectively: 1-first takes over, 2-first otic placode, 21-left end ring, 22 right-hand member rings, 23-second otic placode, 3-first bellows, the left joint of 31-, 4-first pull bar, 41-second pull bar, 5-balance bellows, 51-middle joint, 6-through hole, 7-second bellows, 71-right connector, 8-second take over.
Embodiment
Existing accompanying drawings the specific embodiment of the present invention.
This corrugated expansion joint comprises balance bellows 5, the first bellows 3 and the second bellows 7 is welded with respectively by middle joint 51 at the two ends of balance bellows, the caliber of the first bellows is equal with the caliber of the second bellows, and the caliber of described balance bellows is greater than the caliber of the first bellows.First bellows left end is welded with left joint 31, left joint one end is welded with the first adapter 1, the right-hand member of the second bellows is welded with right connector 71, right connector one end is welded with the second adapter 8, first adapter is used for being connected with pipeline with the second adapter, the gap produced when line expands or shrinks between the first adapter 1 and the second adapter 8 end face in opposite directions when pipeline is compressed or extending thereupon, the middle joint 51 at the two ends of balance bellows is welded with circular left end ring 21 respectively, right-hand member ring 22, left joint 31 is welded with the first otic placode 2, right connector 71 is welded with the second otic placode 23, polylith first otic placode 2 is arranged symmetrically on the cylindrical of left joint, the first pull bar 4 is provided with between first otic placode and right-hand member ring 22, polylith second otic placode 23 is arranged symmetrically on the cylindrical of right connector, the second pull bar 41 is provided with between second otic placode and left end ring 21.
Its working principle is, select the ratio of caliber of the balance caliber of bellows and the first bellows, the second bellows, the thrust that hydrodynamic pressure can be made to produce in balance bellows is greater than the thrust in the first bellows, the second bellows, under the effect of hydrodynamic pressure, balance bellows extend vertically, make the first bellows by the first pull bar and the second pull bar, the second bellows compressed, the thrust that hydrodynamic pressure causes is balanced, the length of corrugated expansion joint is not changed, and the thrust that hydrodynamic pressure causes does not act on the equipment be connected with compensator; Its stress changes thrust-balancing of corrugated expansion joint when pipeline is because expanding with heat and contract with cold, the length of corrugated expansion joint is compressed thereupon or is stretched, realize the compensating action to pipeline.
For the deadweight reducing corrugated expansion joint makes bellows be out of shape and prevent the phenomenon making bellows be out of shape artificial in an installation, described first adapter extends to the middle part of right connector to the right through balance bellows, the first bellows, the second bellows, first adapter and second take between gap should meet the line compensating pipeline and expand, the tube wall that first adapter is positioned at the first bellows, the second bellows and balance bellows is provided with through hole 6, through hole plays drainage, and the thrust-balancing function of balance bellows to the first bellows, the second bellows is not reduced.
