Abstract
The utility model relates to a pressure balance-type compensator for a particular external-broaching straight pipe, which comprises a left corrugated pipe, a right corrugated pipe and a balance corrugated pipe, wherein the left and the right corrugated pipes are respectively connected with the balance corrugated pipe through two connection pipes, a connector piece which is connected with the right end of the right corrugated pipe is connected with the left end of the balance corrugated pipe and the right end of the left corrugated pipe through an upper and a lower pull rods, and a connector piece which is connected with the left end of the left corrugated pipe is connected with the right end of the balance corrugated pipe and the left end of the right corrugated pipe through a front pull rod and a rear pull rod. Two ends of the pull rod are respectively provided with a spherical nut and a conical washer in a matching way. The pressure balance-type compensator can absorb the axial displacement, and also can absorb a given transverse displacement without increasing the length of the corrugated pipes under the condition that the work pressure is small.
Description
Technical field
The utility model relates to corrugated expansion joint, relates in particular to straight pipe pressure-equalizing type compensator.
Background technique
Straight pipe pressure-equalizing type compensator is the mill run in the NBS, its function mainly is the axial displacement that the swollen shrinkage of extraction duct heat produces, under the situation that the product length overall is restricted, existing straight pipe pressure-equalizing type compensator does not possess the lateral displacement of absorption function substantially.
The model utility content
The utility model provides the special outer stretching pipe pressure balance type compensator that can absorb certain lateral displacement at above-mentioned the deficiencies in the prior art.
In order to solve the problems of the technologies described above, the utility model adopts following technological scheme:
Special outer stretching pipe pressure balance type compensator, comprise left and right bellows and balance bellows, left and right bellows is connected with the balance bellows by two connecting tubes respectively, two pull bars were connected with the left end of balance bellows and the right-hand member of left bellows about the adapter piece of right bellows right-hand member passed through, and the adapter piece of left bellows left end is connected with the right-hand member of balance bellows and the left end of right bellows by former and later two pull bars.
Further, described each pull bar two ends are respectively installed with spherical nut and the taper washer that is connected; The adapter piece right-hand member of left side bellows left end connects guide shell, and the adapter piece left end of right bellows right-hand member connects guide shell, and described two guide shells are arranged on the same axis and are interlaced.
Technique effect of the present utility model is: under the less situation of working pressure, the length that does not need to increase bellows can absorb a certain amount of lateral displacement.
Description of drawings
Fig. 1 is a structural representation of the present utility model, broken section among the figure;
Fig. 2 is the enlarged view at A place among Fig. 1.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is further described.
See Fig. 1, the utility model comprises balance bellows 3, left side bellows 1 is connected with balance bellows 3 with connecting tube 5 by connecting tube 4 respectively with right bellows 2, adapter piece 7 right-hand members connect guide shell 14, adapter piece 6 left ends connect guide shell 15, and guide shell 14 and guide shell 15 are on same axis and interlaced.Two pull bars 8 were connected with the left end of balance bellows 3 and the right-hand member of left bellows 1 about the adapter piece 6 that right bellows 2 right-hand members connect passed through, and the adapter piece 7 that left bellows 1 left end connects is connected with the right-hand member of balance bellows 3 and the left end of right bellows 2 by former and later two pull bars 9.Pull bar 8 and pull bar 9 are as follows with the annexation of described each bellows: see Fig. 1, with pull bar 8 is example, two pull bars 8 are with respect to the axis symmetry up and down, and two ends, pull bar 8 left and right sides are passed connecting plate 13 that is welded on balance bellows 3 left ends and the connecting plate 16 that is welded on the adapter piece 6 respectively; See Fig. 2, locking nut 10 and Ball faced nut 11 are threaded with the left end of pull bar 8, about two taper faced washers 12 be linked in respectively on the pull bar 8 and with the both sides butt of connecting plate 13, the conical surface part of taper faced washer 12 and the land portions butt of Ball faced nut 11,10 pairs of Ball faced nuts 11 of locking nut and taper faced washer 12 play the role of fastening, and pull bar 8 right-hand members are identical with the annexation and the left end of connecting plate 16; Former and later two pull bars 9 are also with respect to the axis symmetry, the two ends of former and later two pull bars 9 respectively with adapter piece 7 and identical with the two ends of the linkage structure of the left end of the right-hand member of balance bellows 3 and right bellows 2 and pull bar 8.
Be connected between the pipeline during the utility model work, when pipeline produces axial displacement, left side bellows 1 and right bellows 2 are compressed together, because left bellows 1 and right bellows 2 are connected with balance bellows 3 with pull bar 8 by pull bar 9 respectively, then balance bellows 3 is stretched, thereby has absorbed the axial displacement of external pipe.Guide shell 14, guide shell 15 can be prevented the ducted medium contact of system bellows, avoid bellows to be subjected to corrosion failure.
When lateral displacement appearred in pipeline, angular variation and axial deformation that connecting tube 4, connecting tube 5 produce trace had promptly absorbed lateral displacement, thereby have realized under the prerequisite that does not change the product length overall, can absorb axial displacement, can absorb lateral displacement again; Because pull bar 8, pull bar 9 two ends have the Ball faced nut 11 and the taper faced washer 12 that can make its lateral rotation, pull bar 8, pull bar 9 can rotate thereupon, thereby avoid pull bar 8,9 pairs of connecting tubes 4 of pull bar, connecting tube 5 to produce unbalanced forces when connecting tube 4, connecting tube 5 absorption lateral displacements like this.
