Description
Technical field
The utility model relates to a kind of parts of high-power transformer fuel tank, specifically a kind of high-power transformer oil tank sealing device.
Background technology
Oil tank of transformer, as the critical piece of transformer, is widely used in oil-cooled transformer.In oil tank of transformer, owing to stocking a large amount of transformer Coolings, use oily, and the operation that fuel feeding occurs or reclaim fluid for the variation of transformer inner fluid, when fuel tank temperature is higher, the variation of this fluid easily causes the sealing effectiveness of oil tank of transformer to reduce, produce the leakage of transformer fluid, cause environmental pollution and fluid waste, even can have influence on normal work and the working life of transformer.So the quality of the sealing effectiveness of oil tank of transformer directly has influence on normal operation and the working life of transformer.
Existing fuel tank sealing device of transformer is that the sealing joint strip that a circle is made by fourth eyeball material is set between casing and case lid, sealing adhesive tape top and bottom are inlaid in respectively in the seal groove arranging on case lid and casing, although can reach basic sealing effectiveness, the leakage of fluid still easily occurs in fluid change procedure; And, a fuel tank sealing device of transformer leakage side is outside because being subject to for a long time irradiation and oxidation meeting aging cracking gradually, once transformer aging cracking just there will be Seepage, now transformer just needs to stop transport to repair, change sealing joint strip, manpower but also affect normal production has not only wasted financial resources.So, in order to solve the deficiency of existing fuel tank sealing device of transformer, need a kind of fuel tank sealing device of transformer that can efficient sealed fuel tank, to improve operating efficiency and the working life of transformer, avoid oil liquid leakage to produce environmental pollution and the wasting of resources.
Summary of the invention
The purpose of this utility model is just to provide high-power transformer oil tank sealing device, solves problems of the prior art.
The purpose of this utility model is achieved through the following technical solutions: a kind of high-power transformer oil tank sealing device, casing is provided with top box edge, nowel edge, described nowel is provided with boss along inner side, described top box is provided with along inner side with nowel along the scrobicular ring mating, between boss and scrobicular ring, be provided with spacing preiection, the first seal groove, the second seal groove, the first sealing joint strip and the second sealing joint strip are housed in the first seal groove and the second seal groove, and the second seal groove outside is provided with the bolt on fastening top box edge, nowel edge.
Further, described top box edge, nowel are respectively equipped with upper scrobicular ring and lower concave ring along outside, and sealing shroud is sleeved on scrobicular ring and lower concave ring.
Further, described upper scrobicular ring and the degree of depth of lower concave ring and the wall thickness of sealing shroud are suitable, make top box edge, nowel along mutually concordant with the outer surface of sealing shroud.
Further, the first described sealing ring is acrylonitrile-butadiene rubber bar.
Further, the second described sealing ring is acrylate rubber bar.
The utlity model has following beneficial effect:
The utility model is provided with two seal grooves and two sealing joint strips, inner seal adhesive tape one adopts oil resistant and rebound performance excellence, but the acrylonitrile-butadiene rubber bar that ageing-resistant performance is poor, sealing rubber strip for outer side of side two adopts ageing-resistant performance excellent, but the acrylate rubber bar that rebound performance is slightly poor, bears main sealing function by the acrylonitrile-butadiene rubber bar of inner side, the isolated air of the acrylate rubber bar in outside or chlorohydrin rubber bar and sunlight etc., can efficient sealed oil tank of transformer, improve the sealing property of fuel tank.Nowel has increased a boss along inner side, top box arranges scrobicular ring along correspondence, and scrobicular ring shelters from sealing ring, makes sealing ring avoid rainwater immersion, solar radiation, and section, to extend its useful life, guarantees the sealing effectiveness of seal.Further, upper and lower case is arranged with sealing shroud along outside, and further enhanced leaktightness effect, avoids seal to be directly exposed to being subject in air illumination and oxidation and aging cracking is avoided occurring Seepage because of seal aging cracking.The utility model is reasonable in design, good seal performance, has solved existing oil tank of transformer because the problem of Seepage appears in sealing joint strip aging cracking, has improved sealing effectiveness and the working life of sealing ring, has reduced use cost.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the partial enlarged drawing of Fig. 1.
The double accompanying drawing that makes an abstract of Fig. 2.
In figure, casing 1, top box along 2, bolt 3, sealing shroud 4, nowel be along the 5, second sealing joint strip 6, the first sealing joint strip 7, spacing preiection 8, boss 9, scrobicular ring 10, lower concave ring 11, upper scrobicular ring 12.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1, 2, a kind of high-power transformer oil tank sealing device, casing 1 be provided with top box along 2, nowel is along 5, described nowel is provided with boss 9 along inner side, described top box is provided with along inner side with nowel along the scrobicular ring 10 mating, between boss 9 and scrobicular ring 10, be provided with spacing preiection 8, the first seal groove, the second seal groove, the bolt 3 that the first sealing joint strip 7 and the second sealing joint strip 6, the second seal groove outsides are provided with fastening top box edge, nowel edge is housed in the first seal groove and the second seal groove.
