Description
Technical field
The utility model is related to field transformer, more particularly to a kind of sealing device of oil tank of transformer.
Background technology
Liquid soaking transformer fuel tank is made up of case lid and fuel tank, and multiple is set by being corresponded to respectively on case lid and fuel tank edge
Bolt hole, is linked into an integrated entity case lid and fuel tank with bolt.Case lid is placed on fuel tank assigned position during installation, case lid and case is directed at
Along upper bolt hole, bolt is placed and tightened on request, the structure is higher to the operation technological requirement of the lower fuel tank of device body lifting, case
Cap bore is docked relatively difficult with case along upper hole, is more bothered in operation, and the sealing between oil tank of transformer and case lid
Energy requirement is also high, is all in the past that the mode that sealing strip is directly set between case lid and fuel tank edge is solved, but in fastening spiral shell
Influence is extruded during bolt, sealing strip can produce the phenomenon of displacement sideslip, so as to cause sealing effectiveness undesirable, such as the patent No.
A kind of new-type case of the oil tank of transformer of CN204809008U along structure, its in case along welded top positioning strip by way of pair
Sealing strip is fixed, and positioning strip also only exists stud and interior between positioning strip, then during fabrication in order to ensure oil
The sealing property of case, welding requirements of the positioning strip with case between just compares high, because positioning strip quantity is many and length is more long, nothing
Doubting can increase no small difficulty to the processing of equipment, and because there is no the presence of sealing strip between stud and outer positioning strip,
So when mounted, sealing strip is influenceed by case lid extruding, will necessarily between two studs between stud and outer positioning strip
Extend, so that sealing strip and the interior sealing property that space is produced between positioning strip, fuel tank is reduced；Also it is exactly, because
For stud is fastened through the through hole on case lid and by nut, then will necessarily there are some small gaps between stud and through hole,
So this may also occur the possibility that liquid oozes out from the small gap in fuel tank.
The content of the invention
The purpose of this utility model is exactly that a kind of sealing device of oil tank of transformer is provided to solve the above problems.
Technical problem of the present utility model is mainly addressed by following technical proposals：
A kind of sealing device of oil tank of transformer, including casing and the case lid of casing top is covered on, the casing top
There is a circle groove along its case is circumferentially arranged, and stud is uniformly provided with groove, be also filled with its further groove matched
Sealing strip, the sealing strip be provided with correspondence stud through hole, and via top be provided be coaxial therewith set ring packing
Projection, wherein stud sequentially pass through the screw on corresponding through hole, ring packing projection and case lid from lower to upper.
Preferably, the case lid top is provided with the nut being screwed onto on stud, and the stud between nut and case lid
It is above also outer to be cased with pad.
Preferably, the case lid bottom is provided with the locating slot being adapted with corresponding ring packing projection.
Preferably, the stud is located at the middle of recess width, and multigroup stud is uniformly arranged along groove length direction,
Welded with bottom portion of groove the stud bottom.
Preferably, the raised internal diameter of the ring packing is not more than through-hole diameter, and ring packing it is raised with sealing strip it
Between be integrated setting.
The beneficial effects of the utility model are：The utility model is no longer needed in case along upper punching, and case is whole along turning into one
Body, enhances the mechanical strength on case edge, and new structure causes that case lid becomes simple with case along docking operation, and sealing strip and annular
Seal convexity can then strengthen the sealing property of fuel tank, and groove then can be convex to corresponding sealing strip and ring packing with locating slot
Positioning action is played, the possibility for making it not to be subjected to displacement.
