Abstract
The utility model relates to a general compensator, in particular to a general axial compensator, which comprises a first flange (1), a second flange (2), a stud (3), disc springs (4), an outer barrel (5), a standby cap (6), a washer (7) and a bellows (8), wherein one end of the stud (3) is connected with the first flange (1) through nuts and the washer (7), the other end of the stud (3) is connected with the outer barrel (5), the two ends of the interior of the outer barrel (5) are provided with the disc spring (4), the other end of the outer barrel (5) passes through the second flange (2) to be connected with the standby cap (6), and the bellows (8) is arranged between the first flange (1) and the second flange (2). The utility model has compact structure, large compensation quantity, low flow resistance, zero leakage, no bind plate force and low cost.
Description
Technical field:
The utility model relates to a kind of general compensator, relates in particular to a kind of common shaft to compensator.
Background technique:
Be applied to high pressure combined electrical apparatus, pressurized gas insulated switch, high-tension switch cabinet at present and remove spring assembly, all there are some shortcomings in the nose balance device that is applied in marine main engine gas exhaust duct, all kinds of pump discharges: big to fixed support thrust, thus cause the cost height; Security is relatively poor, and working life is short, and compensation rate is less.
The model utility content:
The purpose of this utility model provides a kind of common shaft to compensator, and its compact structure, compensation rate are big, and flow resistance is little, zero leakage, and no blind plate power, cost is low.
In order to solve the existing problem of background technique, the utility model is by the following technical solutions: it by first flange, second flange, double-screw bolt, belleville spring, urceolus, be equipped with cap, packing ring and bellows and form, one end of double-screw bolt links to each other with first flange by nut and packing ring, the other end of double-screw bolt links to each other with urceolus, the two ends, inside of urceolus are provided with belleville spring, the other end of urceolus passes second flange and is equipped with cap and links to each other, and bellows is arranged between first flange and second flange.
Described first flange and second flange can be rectangles, also can be dishes.
Described packing ring can also can be taper faced washer for spherical washer.
Described bellows is the multi-layer thin wall construction, and two ends are C type ripple, and the centre is a U type ripple.
The utility model is stretching pipeline is carried out nose balance by bellows, the elastic force that the compression of its belleville spring produces is used for balance blind plate power, urceolus plays guiding and power transmission effect, packing ring is keeping allowing the compensator radial displacement under the constant situation of axial force, the axial elongation of restriction compensator, overcome the blind plate power of self, the C type ripple cancellation at bellows two ends is taken over, can under short as far as possible axial dimension, obtain maximum equilibrant force, flange bolt is unaffected, also alternative adapter can compensate and have the adapter effect.
The compact structure, the compensation rate that the utility model has the advantages that it are big, and flow resistance is little, zero leakage, and no blind plate power, cost is low.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Embodiment:
With reference to Fig. 1, this embodiment is by the following technical solutions: it by first flange 1, second flange 2, double-screw bolt 3, belleville spring 4, urceolus 5, be equipped with cap 6, packing ring 7 and bellows 8 and form, one end of double-screw bolt 3 links to each other with first flange 1 by nut and packing ring 7, the other end of double-screw bolt 3 links to each other with urceolus 5, the two ends, inside of urceolus 5 are provided with belleville spring 4, the other end of urceolus 5 passes second flange 2 and is equipped with cap 6 and links to each other, and bellows 8 is arranged between first flange 1 and second flange 2.
Described first flange 1 and second flange 2 can be rectangles, also can be dishes.
Described packing ring 7 can also can be taper faced washer for spherical washer.
Described bellows 8 is the multi-layer thin wall construction, and two ends are C type ripple, and the centre is a U type ripple.
This embodiment is stretching pipeline is carried out nose balance by bellows 8, the elastic force that its belleville spring 4 compression produces is used for balance blind plate power, urceolus 5 plays guiding and power transmission effect, packing ring 7 is keeping allowing the compensator radial displacement under the constant situation of axial force, the axial elongation of restriction compensator, overcome the blind plate power of self, the C type ripple cancellation at bellows 8 two ends is taken over, can under short as far as possible axial dimension, obtain maximum equilibrant force, flange bolt is unaffected, also alternative adapter can compensate and have the adapter effect.
The advantage of this embodiment is that its compact structure, compensation rate is big, and flow resistance is little, zero leakage, and no blind plate power, cost is low.
