Abstract
The utility model discloses a pressure buffering balance structure of a corrugated pipe compensator. The pressure buffering balance structure is arranged on the corrugated pipe compensator mainly composed of a left flange, a corrugated pipe and a right flange. The pressure buffering balance structure comprises a pull rod and a butterfly spring assembly, wherein the butterfly spring assembly is arranged at the right end of the pull rod and comprises a butterfly spring, a butterfly spring adjusting nut, a nut and spherical washers; the nut, the spherical gasket, the right flange, the spherical gasket, the butterfly spring and the butterfly spring adjusting nut are connected in series at the right end f the pull rod from left to right in sequence by the pull rod; the butterfly spring adjusting nut is in thread connection with the right end of the pull rod; the left end of the pull rod is connected with the left flange by the nut and the spherical washers; and the right end of the pull rod is connected with the right flange by the butterfly spring assembly. The pressure buffering balance structure of the corrugated pipe compensator does not need to be provided with a butterfly spring barrel, so that the structure is simplified, the structural size of the compensator is reduced, the manufacturing difficulty is lowered, the manufacturing cost is decreased, and the convenience is provided for assembly and adjustment at the same time.
Description
Technical field
The utility model relates to a kind of elastic buffer equilibrium structure, and specifically, the utility model relates to a kind of elastic buffer equilibrium structure that is applied on the corrugated expansion joint.
Background technique
Corrugated expansion joint is used to compensate owing to pipeline or the equipment size that reason causes is installed or expand with heat and contract with cold etc. and changes, and can absorb the bellows pressure thrust.During compensator work, associated devices is not produced bigger thrust in order to make working pressure, existing technology is provided with the elastic buffer equilibrium structure.The elastic buffer equilibrium structure of technology is made up of dished spring assembly, the pull bar that is connected dished spring assembly one end, packing ring, nut etc. now; Dished spring assembly is to be the main Cylinder shape constructional element that constitutes by dish spring tube, dish spring, dish spring adjusting nut, tube cap etc.; The dish spring is installed on pull bar through dish spring adjusting nut and stretches into the end in the dish spring tube; The other end of pull bar is connected on bellows one side flange through nut, packing ring, and dished spring assembly then runs through bellows opposite side flange through dish spring tube, and connects.The elastic buffer equilibrium structure of technology can play the elastic buffer balanced action when compensator is worked now; But exist certain deficiency: stressed when compensator is worked; The bellows pressure thrust is born by dish spring tube; This just requires dish spring tube to have higher structural strength and rigidity, has increased part manufacture difficulty and manufacture cost; The dish spring is installed in the dish spring tube, adds structural strength and the rigidity requirement of compensator to dish spring tube, makes that dish spring tube boundary dimension is bigger, does not interfere for the dish spring tube that makes bellows and its outside, and the radial structure size of compensator is just bigger; All in dish spring tube, the assembling of elastic buffer equilibrium structure, adjustment are all inconvenient for dish spring, dish spring adjusting nut.
Summary of the invention
The utility model is to the deficiency of existing technology, proposes a kind of simple in structurely, be easy to make, and low cost of manufacture, physical dimension is little, assembling, corrugated expansion joint pressure buffer equilibrium structure easy to adjust.
The utility model is realized technical goal through following technical proposals.
Corrugated expansion joint pressure buffer equilibrium structure, being located at by left flange, bellows, right flange is on the corrugated expansion joint of main member, it comprises pull bar, dished spring assembly; Said dished spring assembly is arranged on the right-hand member of pull bar, comprises dish spring, dish spring adjusting nut, and dish spring adjusting nut is threaded with the right-hand member of pull bar; The left end of said pull bar is connected with left flange through nut, spherical washer, and the right-hand member of pull bar is connected with right flange through dished spring assembly; Its improvements are: said dished spring assembly also comprises nut, spherical washer; Said pull bar is contacted nut, spherical washer, right flange, spherical washer, dish spring, dish spring adjusting nut successively from left to right and is connected on the right-hand member of pull bar.
Further improve as the utility model, on said right flange right side, be provided with case, said case is fixedly connected on the right flange right side, and the spherical washer that is connected the pull bar right-hand member, dish spring, dish spring adjusting nut are covered in its endoporus.
Case plays the proofing dust and protecting effect to dished spring assembly, when needing adjustment dish spring adjusting nut, as long as pull down case, just can carry out.
The utility model compared with prior art has following good effect:
1. need not dish spring tube, reduced number of spare parts like this, make simple in structure; Need not to make that this physical dimension is big, the higher part of requirement of strength, reduced manufacture difficulty and manufacture cost.
2. do not adopt dish spring tube, make the compensator radial dimension reduce greatly yet, reduced material consumption, reduced manufacture cost.
3. when needing adjustment dish spring adjusting nut,, just can adjust easily as long as pull down case.
4. do not adopt dish spring tube, simple in structure, also made things convenient for assembling.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the I part enlarged diagram among Fig. 1.
Embodiment
Below according to accompanying drawing and combine embodiment that the utility model is described further.
Like Fig. 1, corrugated expansion joint pressure buffer equilibrium structure shown in Figure 2; Be located at by left flange 1, bellows 3, right flange 4 on the corrugated expansion joint of main member; It comprises pull bar 2, dished spring assembly 5; The left end of pull bar 2 is connected with left flange 1 through nut, spherical washer, and the right-hand member of pull bar 2 is connected with right flange 4 through dished spring assembly 5; Said dished spring assembly 5 is arranged on the right-hand member of pull bar 2; Comprise dish spring 5.3, dish spring adjusting nut 5.4, nut 5.1, spherical washer 5.2; Pull bar 2 is contacted nut 5.1, spherical washer 5.2, right flange 4, spherical washer 5.2, dish spring 5.3, dish spring adjusting nut 5.4 successively from left to right and is connected on the right-hand member of pull bar 2, and dish spring adjusting nut 5.4 is threaded with the right-hand member of pull bar 2.
In order dished spring assembly to be played the proofing dust and protecting effect; The utility model is provided with case 5.5 on right flange 4 right sides; Case 5.5 is fixedly connected on right flange 4 right sides, and the spherical washer 5.2 that is connected pull bar 2 right-hand members, dish spring 5.3, dish spring adjusting nut 5.4 are covered in its endoporus.When needing adjustment dish spring adjusting nut 5.4,, just can carry out as long as pull down case 5.5.
