Abstract
The utility model discloses a bolt hole that transformer fills oil drain flange and connects, characterized by set up on the ring flange is the waist shape hole of penetrating the form and distributing on the ring flange, implement the fastening radial position in the difference can be adjusted to the bolt in the waist appears the hole on, the takeover of setting on the central hydraulic fluid port of flange is the screwed pipe, the cooperation sets up straight joint, and straight joint's one end is connected through the screw thread with the screwed pipe of takeover, and the other end has the bore with oil pipe matched with. The utility model discloses the usefulness of can uniting between the transformer of multiple different models has reduced the outfit that the flange connects, reduces the transformer and fills the complexity of oil drain process, improves work efficiency.
Description
Technical field
The utility model relates to transformer oil charging-discharging flanged joint, is more particularly that one is suitable for connecting between different model transformer main change and oil supply machine, realizes the piecing devices of transformer oil charging-discharging.
Background technique
Along with the development of electrical network, the quantity of electric substation is also increasing year by year, and the work of maintenance repair and maintenance is very heavy.
Transformer needs repairing in long-term operation, in repairing process, needs profit to want flanged joint main transformer and oil supply machine oil pipe to be coupled together.Due to the difference of transformer model, fuel outlet valve flange bore is not of uniform size, and screw centre distance is also not quite similar.Cause the fit dimension of flange correspondingly to need varied, at every turn before carrying out repairing, first need to select suitable flanged joint; Meanwhile, due to the diversity of flange plate, its oil outlet tube bore differs, and for this reason, also needs the oil pipe being equipped with various different-diameter, this not only adds workload, too increase the outfit of flanged joint.
Model utility content
The utility model is the deficiency for avoiding existing for above-mentioned prior art, a kind of transformer oil charging-discharging flanged joint that can carry out uniting between the transformer of multiple different model is provided, reduce the outfit of flanged joint, reduce the complexity of transformer oil charging-discharging process, increase work efficiency.
The utility model is that technical solution problem adopts following technological scheme:
The structural feature of the utility model transformer oil charging-discharging flanged joint is: the bolt hole arranged on flange plate be on flange plate in penetrate shape distribution waist shaped hole, bolt can adjust in described waist shaped hole implement in different radial positions fastening; The adapter be arranged on flange center's hydraulic fluid port is threaded pipe; Be equipped with straight coupling, one end of described straight coupling is connected by screw thread with the threaded pipe of described adapter, and the other end has the bore matched with oil pipe.
The structural feature of the utility model transformer oil charging-discharging flanged joint is also: in described waist shaped hole one end away from flange center, is between two adjacent waist shaped holes and is provided with circular bolt holes.
The structural feature of the utility model transformer oil charging-discharging flanged joint is also: arrange straight coupling correspondingly according to existing oil pipe bore, adapts to corresponding oil pipe bore to change different straight couplings.
Compared with the prior art, the utility model beneficial effect is embodied in:
1, the oil charging-discharging flanged joint in the utility model can adapt to the transformer of multiple different model to a certain extent, and the different radial position of adjustment bolt in waist shaped hole can complete connection, achieves the versatility of flange.
2, the utility model is threaded straight coupling in the adapter of flange, matches with oil pipe with the straight coupling with the mouth of pipe bore that adapts, and its dismounting is quick, easy to use.
3, the utility model by supporting for straight coupling be polytypic joint, exchange the joint of different model and can realize and the coordinating of oil pipe, form simply, also further simplify outfit.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 a is the straight coupling structural representation of supporting setting in the utility model;
Fig. 2 b and Fig. 2 c is respectively the straight coupling structural representation of the different model of supporting setting in the utility model;
Number in the figure: 1 flange plate, 2 waist shaped holes, 3 adapters, 4 straight couplings, 5 circular bolt holes.
Embodiment
See Fig. 1, in the present embodiment, the structural type of transformer oil charging-discharging flanged joint is, the bolt hole arranged on flange plate 1 be on flange plate 1 in penetrate shape distribution waist shaped hole 2, bolt can adjust in waist shaped hole 2 implement in different radial positions fastening.
As shown in Fig. 1 and Fig. 2 b, the adapter 3 be arranged in the present embodiment on flange center's hydraulic fluid port is threaded pipe; Be equipped with straight coupling 4, one end of straight coupling 4 is connected by screw thread with the screw mouth of adapter 3, and the other end has the bore matched with oil pipe.
For in penetrate shape distribution waist shaped hole 2, due to larger away from the spacing of adjacent two waist shaped holes in one end of flange center at waist shaped hole, therefore the setting of bolt hole can suitably be increased, be in waist shaped hole 2 one end away from flange center in the present embodiment, be between two adjacent waist shaped holes and be provided with circular bolt holes 5.
In the present embodiment, straight coupling 4 is set to the combining form of Multiple Type, selects the straight coupling of different models can to match with the oil pipe bore adapted; Also straight coupling 4 can be set correspondingly according to existing oil pipe bore, to change different straight couplings 4 to adapt to corresponding oil pipe bore.Fig. 2 a, Fig. 2 b and Fig. 2 c are respectively the straight coupling of different model, and its caliber of one end wherein straight coupling 4 shown in Fig. 2 a is connected for an oil pipe is maximum, and its caliber of one end that straight coupling 4 shown in Fig. 2 c is connected for an oil pipe is minimum.
