Abstract
The utility model relates to a round header pipe end sealing structure of a transformer and belongs to the technical field of transformer production. The technical scheme is that the round header pipe end sealing structure of the transformer comprises a round header pipe (1), fastening bolts (2), hexagon nuts (3), a concave step rubber ring (4) and a cover plate (5), wherein a plurality of hexagon nuts (3) are evenly fixed on the outer wall of the end of the round header pipe (1) in the peripheral direction, the cover plate (5) is provided with installing holes corresponding to the hexagon nuts (3) in the peripheral direction and connected with the round header pipe (1) through the fastening bolts (2) and the hexagon nuts (3), the concave step rubber ring (4) is arranged between the cover plate (5) and the round header pipe (1), provided with a step-shaped edge portion in the peripheral direction and of a concave structure. The round header pipe end sealing structure of the transformer has the advantages that the round header pipe end sealing effect of the transformer is good, materials are remarkably saved, the working efficiency is improved, and the labor intensity of workers is reduced.
Description
Technical field
The utility model relates to a kind of transformer circle header pipe termination enclosed construction, belongs to transformer production technical field.
Background technique
Oil tank of transformer outer surface, disposes transformer circle header pipe.The main body of circle header pipe is thick walled steel tube.Because inwall needs to check, spray paint, thus need the two-port of thick walled steel tube to open wide before general assembly, at present, transformer circle header pipe termination enclosed construction, generally all adopt welding flange, in the time of follow-up general assembly operation, then flange plate end face is loaded onto to rubber seal, round cover board sealing.After fit sealing, become the sealing of semipermanent pipe end.There is following shortcoming in this sealing configuration:
(1) nut space of flange plate and round cover board installation place is little, and spanner rotates wastes time and energy, if add the space at big nut place, need to strengthen flange plate diameter, expends raw material, also consumes gas cutting fuel, machine cutting tool, drill bit and auxiliary material.
(2) flange plate is welded on after round header pipe, also needs to carry out weld inspection leak test, and process is very loaded down with trivial details.
Model utility content
The utility model object is to provide a kind of transformer circle header pipe termination enclosed construction, utilizes cover plate and concave station rubber ring to seal, and sealing effect is good, solves the problem existing in background technique.
The technical solution of the utility model is:
A kind of transformer circle header pipe termination enclosed construction, comprise round header pipe, clamping bolt, hexagon nut, concave station rubber ring and cover plate, on the outer wall circumferencial direction of circle header pipe termination, evenly fix several hexagon nuts, cover plate is along the circumferential direction provided with the mounting hole corresponding with hexagon nut, cover plate is connected with circle header pipe by clamping bolt, hexagon nut, between cover plate and circle header pipe, be provided with concave station rubber ring, described concave station rubber ring limit portion circumferencial direction is stepped, is concave structure.
On the outer wall circumferencial direction of described round header pipe termination, evenly fix eight hexagon nuts, concave station rubber ring size is mated with circle header pipe external diameter.Concave station rubber ring is easy for installation, does not drop, and in the time of clamping bolt, is difficult for displacement, and transformer circle header pipe termination is sealed more.
The beneficial effects of the utility model are: transformer circle header pipe termination sealing effect is good, significantly saves material, has improved working efficiency, reduces labor strength.

Embodiment
Below in conjunction with accompanying drawing, by example, the utility model is described in further detail.
With reference to accompanying drawing 1, 2, 3, 4, 5, a kind of transformer circle header pipe termination enclosed construction, comprise round header pipe 1, clamping bolt 2, hexagon nut 3, concave station rubber ring 4 and cover plate 5, circle header pipe 1 adopts thick walled steel tube, eight hexagon nuts 3 of uniform welding on circle header pipe 1 termination outer wall circumferencial direction, each hexagon nut 3 and circle header pipe 1 border full weld, meet welding requirements, cover plate 5 is along the circumferential direction provided with eight of the mounting holes corresponding with hexagon nut 3, cover plate 5 is by clamping bolt 2, hexagon nut 3, mounting hole is fastenedly connected with circle header pipe 1, between cover plate 5 and circle header pipe 1, be provided with concave station rubber ring 4, described concave station rubber ring 4 limit portion circumferencial directions are stepped, for concave structure, concave station rubber ring 4 sizes are mated with circle header pipe 1 external diameter.Concave station rubber ring adopts concave structure, easy for installation, does not drop, and in the time of clamping bolt, is difficult for displacement, and transformer circle header pipe termination is sealed more.
