Abstract
The utility model discloses a disc spring type expansion joint for a gas insulated switchgear, and provides a disc spring type expansion joint serving as a position compensation and pipeline sealing device for the GIS (gas insulated switchgear). The disc spring type expansion joint solves the problem that the GIS needs one expansion joint serving as the position compensation and pipeline sealing device for the GIS. The disc spring type expansion joint is characterized by comprising an expansion joint body and disc spring components, the expansion joint body comprises a left flange plate, a left end pipe, a corrugated pipe, a right end pipe and a right flange plate which are sequentially connected, a sleeve positioning hole is formed in each left lug plate, a pull rod positioning hole is formed in each right lug plate, each disc spring component comprises a body and a displacement compensation device, a sleeve and an outer pull rod of each disc spring component are inserted into the corresponding sleeve positioning hole and the corresponding pull rod positioning hole respectively, and the displacement compensation devices are arranged on the disc spring components. The disc spring type expansion joint has the advantages that the elastic force of the disc spring components can bear the pressure and the pushing force of a pipeline in the initial gas-filled state of the pipeline, and internal discharge can be avoided.

Technical field
The utility model relates to the expansion joint in a kind of fully closed combined electric unit (English full name is Gas lnsulated Switchgear or Gas Insulated Substation, and it is abbreviated as GIS), is a kind of dish spring type expansion joint specifically.It is used for sulphur hexafluoride (SF
6) sealing of gas insulated metal enclosed swit chgear electric transmission line.
Background technique
Fully closed combined electric unit (GIS) has been widely used in modern electric production and transportation art.Electric pressure is more high, and its technical economic benefit is more good.Along with the Chinese society rapid economy development, the continuous growth of electricity need load, more and more higher to the requirement of power supply reliability.Advantages such as GIS is little with its floor space, and is safe and reliable to operation, and the repair cycle is long, and is easy for installation have become the leading equipment in the secondary distribution system.
GIS inner filling SF
6Gas-insulated medium, and work in high electric-force gradient environment, so need a kind of as the position compensation of GIS and the expansion joint of seal for pipe joints device, be used for regulating that installation deviation, dismounting equipment, compensates cause expands with heat and contract with cold and effect such as vibration damping and vibration isolation, also will have performances such as the high cycle-index of low stress.
Summary of the invention
For solving the problems of the technologies described above, the purpose of this utility model provides a kind of dish spring type expansion joint.
The purpose of this utility model is achieved in that it is made up of expansion joint and dished spring assembly;
Said expansion joint is: left flange plate, left end pipe, bellows, right-hand member pipe and right side flange plate are connected successively, edge at left flange plate evenly arranges at least two left otic placodes, left flange plate and left otic placode are one, establish dished spring assembly sleeve pipe positioning hole (claiming the sleeve pipe positioning hole) on each left otic placode; Evenly weld the auris dextra plate on right-hand member pipe outer wall, left and right otic placode is corresponding one by one, establishes the positioning hole (claiming the pull bar positioning hole) of dished spring assembly pull bar on each auris dextra plate;
Said dished spring assembly is made up of body and bit shift compensation device, it (is that sleeve pipe is equivalent to cylinder that said body is formed air cylinder structure by sleeve pipe, pull bar and packing ring, pull bar is equivalent to piston rod, packing ring is equivalent to piston), whole pull bar is divided into inside and outside pull bar, draw-in bar is in sleeve pipe, and outside link is screw rod outside sleeve pipe; The dish spring is enclosed within on the draw-in bar, and places between guide pin bushing seat (being equivalent to the cylinder upper end cap) and the packing ring, is threaded to the guide pin bushing seat outside with the outside link nut engaged; Sleeve pipe and the outside link of each dished spring assembly are inserted sleeve pipe positioning hole and pull bar positioning hole respectively, on the outside link of the every side of auris dextra plate, screw in spheric seating and Ball faced nut successively, outside link is fixed on the auris dextra plate; Said bit shift compensation device comprises, spherical washer is fixed on the outer wall of sleeve pipe, and at least two bolts hole and bolt evenly are set on the circumference of spherical washer, and each bolt screws on the left otic placode, between left otic placode and spherical washer taper faced washer is set, spherical washer and taper faced washer cooperate.
During use, the mounting flange on the pipeline of mounting flange of the present utility model and GIS is connected.In the original state of pipeline inflation, the elastic force of dished spring assembly can be born the pressure thrust of pipeline.
Compared with prior art, good effect of the present utility model is: can absorb the displacement from pipeline axial, in the original state of pipeline inflation, the elastic force of dished spring assembly can be born the pressure thrust of pipeline, can avoid internal discharge.
