Abstract
The invention relates to a transformer auxiliary component and particularly relates to an air relief cock used for performing air relief on oil-immersed electric transmission and transformation equipment. The air relief cock comprises a cock base and a cock body, wherein the diameter of the middle section of the cock body is greater than those of two ends of the cock body, the outer walls of two ends of the cock body are provided with threads, and the cock body is internally provided with an exhaust passage which is longitudinally through; the cock base is internally provided with a through hole, the upper part of the through hole is cylindrical, the internal diameter of the through hole is matched with the lower end of the cock body, the middle part of the through hole is conical, the lower part of the through hole is cylindrical, and the middle part of the through hole is provided with a sealing gasket; and the lower end of the cock body is connected with the cock base, and the upper end of the cock body is connected with a guard tube. The air relief cock is connected with the guard tube, so that effluent transformer oil is guided into an oil drum during air relief, the transformer oil is prevented from polluting the environment, and the environmental requirements of users can be met. The air relief cock has the advantages of reasonable structure, reliable seal, convenience in operation and the like.
Description
Technical field
The present invention relates to a kind of transformer auxiliary element, particularly relate to a kind of air relief cock be used for the venting of oil immersed type power transmission and transforming equipment.
Background technology
During the venting of the oil immersed type power transmission and transforming equipment such as power transformer, some gases can be assembled higher than in the rising seat of exhaust outlet or pipeline, in order to gas discharging here is clean, need, at these positions, air relief cock is installed, thus avoid the normal operation of the equipment that affects.The base of traditional air relief cock is welded on the body of transformer, and air relief cock lower end, by screw thread and base engagement, seals with sealing gasket between air relief cock and base.Unscrewing air relief cock when exitting, after venting, tightening air relief cock.Therefore in deflation course, can spray transformer oil unavoidably, and air relief cock temporarily can only cover with useless cloth, transformer oil easily flows on transformer body or ground, contaminated environment.Along with the progress of transformer technology, the requirement of client to environment is more and more higher, is therefore badly in need of improving traditional air relief cock.
Summary of the invention
For the above-mentioned defect that existing air relief cock exists, the structure of the present invention to air relief cock is improved, and air relief cock connects protecting tube, and the oil of discharging is imported oil drum, preventing pollution environment.
The concrete technical scheme that the present invention adopts is as follows:
A kind of air relief cock, comprise obturating plug and cock body, feature is: described cock body stage casing diameter is greater than two ends diameter, and two ends outer wall is equipped with screw thread, is provided with longitudinally through exhaust passage in cock body; Be provided with a through hole in described obturating plug, through hole top is cylindrical, and its internal diameter matches with cock body lower end, and be taper in the middle part of through hole, bottom is cylindrical, and portion is provided with a sealing gasket in through-holes; Cock body lower end is connected with obturating plug, and its upper end connects a protecting tube.
The present invention breaks traditions the constraint of air relief cock shape, cock body two ends are all arranged helicitic texture, obturating plug and protecting tube can be connected respectively, and exhaust passage is set in cock body, the convenient transformer oil that will be flowed out by exhaust passage and protecting tube when venting imports oil drum, prevents the oil pollution environment sprayed.In addition, for realizing the effective control to venting, periphery and the obturating plug of cock body are sealed and matched completely, and the exhaust passage by means of only cock body is vented, for this reason, taper is set in the middle part of through hole in obturating plug, bottom is set to less cylindrical of diameter, and after obturating plug welds with transformer, cylindrical holes communicates with inside transformer, one sealing gasket is arranged at cylindrical holes top, is sealed by the squeezing action of cock body to sealing gasket.When tightening cock body, sealing gasket pushes down cylindrical holes, prevents gas from discharging, when needs are vented, turn on cock body, sealing gasket resilience, gas is discharged from cylindrical holes, through the exhaust passage of cock body, flow into protecting tube, when gas drains soon, transformer oil is had to flow out, also flow into protecting tube through exhaust passage, reclaim, avoid causing environmental pollution.
For realizing the excellent sealing to cylindrical holes, sealing gasket surrounding fully will contact with obturating plug inwall, and therefore, preferred sealing gasket is spherical or oval spherical.
In addition, be provided with sealing ring at upper and lower both sides, cock body stage casing and obturating plug and protecting tube contact position, ensure the sealing effectiveness of cock body periphery.
The present invention also comprises a cock cap, being connected, realizing the sealing to air relief cock for replacing protecting tube when not exitting with cock body upper end.
The present invention connects protecting tube on air relief cock, when exitting, the transformer oil flowed out can be imported oil drum, preventing transformer oil contaminated environment, meeting the requirement of user to environment.The present invention also have rational in infrastructure, seal the advantages such as reliable, easy to operate.
