Background technique
Oil tank of transformer outer surface, is configured with transformer circle header pipe.The main body of circle header pipe is thick walled steel tube.Because inwall needs to check, spray paint, so need the two-port of thick walled steel tube to be unlimited before general assembly, at present, transformer circle header pipe termination enclosed construction, generally all adopt welding flange, when follow-up general assembly operation, then flange plate end face is loaded onto 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, needs to strengthen flange plate diameter, expends raw material, also consume gas cutting fuel, machine cutting tool, drill bit and auxiliary material.
(2), after flange plate is welded on round header pipe, also need to carry out weld inspection leak test, process is very loaded down with trivial details.
Summary of the invention
The object of the invention is to provide the header pipe termination enclosure method of a kind of transformer circle, and utilize cover plate and concave station rubber ring to close, sealing effect is good, solves Problems existing in background technique.
Technological scheme of the present invention is:
The header pipe termination enclosure method of a kind of transformer circle, comprise following steps: 1. round header pipe termination outer wall circumferentially evenly fixes several hexagon nuts, cover plate is along the circumferential direction provided with the mounting hole corresponding with hexagon nut, and cover plate is connected with circle header pipe by clamping bolt, hexagon nut; 2. be provided with concave station rubber ring, described concave station rubber ring between cover plate and circle header pipe, the circumferencial direction of rubber ring edge is stepped, and entirety is the concave structure of middle with hole; The diameter of concave station rubber ring intermediate hole is identical with the internal diameter of circle header pipe, and the outer tube wall of circle header pipe termination withstands between the ladder of concave station rubber ring just, the step structure of concave station rubber ring with justify header pipe termination outer tube wall and mate and seal.
Described round header pipe termination outer wall circumferentially evenly fixes eight hexagon nuts, and the step place of concave station rubber ring mates with circle header pipe termination outer tube wall.Concave station rubber ring is easy for installation, does not drop, the not easily displacement when clamping bolt, makes transformer circle header pipe termination more closed.
The present invention has got rid of flange plate, adopts GB hexagon nut, is welded on round header pipe termination outer wall circumferentially, substitute flange plate, abbreviation enclosed construction.Concave station rubber ring is designed to concave station shape, and concave station object is easy for installation, does not drop, the rubber ring not easily displacement when clamping bolt.

Embodiment
Below in conjunction with accompanying drawing, by example, the invention will be further described.
The header pipe termination enclosure method of a kind of transformer circle, comprise following steps: 1. round header pipe 1 termination outer wall circumferentially evenly fixes several hexagon nuts 3, cover plate 5 is along the circumferential direction provided with the mounting hole corresponding with hexagon nut, and cover plate is connected with circle header pipe by clamping bolt 2, hexagon nut; 2. be provided with concave station rubber ring 4, described concave station rubber ring between cover plate and circle header pipe, the circumferencial direction of rubber ring edge is stepped, and entirety is the concave structure of middle with hole; The diameter of concave station rubber ring intermediate hole is identical with the internal diameter of circle header pipe, and the outer tube wall of circle header pipe termination withstands between the ladder of concave station rubber ring just, the step structure of concave station rubber ring with justify header pipe termination outer tube wall and mate and seal.
Described round header pipe termination outer wall circumferentially evenly fixes eight hexagon nuts, and the step place of concave station rubber ring mates with circle header pipe termination outer tube wall.Concave station rubber ring is easy for installation, does not drop, the not easily displacement when clamping bolt, makes transformer circle header pipe termination more closed.
The present invention has got rid of flange plate, adopts GB hexagon nut, is welded on round header pipe termination outer wall circumferentially, substitute flange plate, abbreviation enclosed construction.Concave station rubber ring is designed to concave station shape, and concave station object is easy for installation, does not drop, the rubber ring not easily displacement when clamping bolt.
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 termination outer wall circumferentially evenly fixes 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, is provided with concave station rubber ring between cover plate and circle header pipe; Described concave station rubber ring, the circumferencial direction of rubber ring edge is stepped, and entirety is the concave structure of middle with hole; The diameter of concave station rubber ring intermediate hole is identical with the internal diameter of circle header pipe, and the outer tube wall of circle header pipe termination withstands between the ladder of concave station rubber ring just, the step structure of concave station rubber ring with justify header pipe termination outer tube wall and mate and seal.
In the present embodiment,
Adopt GB hexagon nut, quantity correspondence configuration cover plate hole count used: 4 or 6 or 8 (the present embodiment is 8 holes, nut).Determine at circle header pipe external diameter with simply welding positioning tool (can reuse), each nut and circle header pipe border full weld.
For convenience of installing, sealing rubber ring being made concave station shape, reaching the true position of installation correct, stable fast.The girth of concave station rubber ring of the present invention, than all length of the rubber ring of background technique, shows that (girth) distance of closed leakage of oil is relatively short, and the distance closing leakage of oil is shorter, and sealing effect is just more reliable.
Install due to clamping bolt of the present invention and reduce to direction, the center of circle, cover plate of the present invention is less than the diameter of the round cover board of background technique.When thickness is equal, diameter is less, and relative intensity is just more reliable.Cover plate of the present invention is more reliable than background technique.
Invention increases mechanical strength and reliability.Because inside transformer oil is certain to the pressure of oil tank wall, inner tube wall, area is less be stressed less.Cover plate is little by the area of oil pressure, and cover plate is relative to just more reliable.
Data compare:
There is flange plate enclosed construction A, background technique circle header pipe termination, and flange plate consumption steel 20 kilograms, dome plate loss steel 12 kilograms, add up to consumption steel 32 kilograms.
The present invention is without flange plate, and cover plate consumption steel 9 kilograms, add up to consumption steel 9 kilograms.
Add up to and save consumption steel 23 kilograms.
There are flange plate manufacturing process gas cutting, circle car, boring in B, background technique circle header pipe termination, and leak test man-hour, other unproductive time adds up to 12 man-hours, and namely the present invention saves 12 man-hours.
