Abstract
The utility model relates to the reinforced quiet end cap sealing structure of a kind of high-pressure vacuum switch pipe, comprise quiet end casing and sealing ring, described quiet end casing is ring-type, the interior ring edge of quiet end casing and place, outer shroud edge are provided with respectively the straight mouthful flange of interior ring and the straight mouthful flange of outer shroud, described sealing ring middle part is provided with vertebra shape and closes up, port sealing welding of the straight mouthful flange of outer shroud of described quiet end casing and described sealing ring.The beneficial effects of the utility model are: strengthened on the one hand the impact strength of the quiet end cap part of vacuum switch tube, when preventing from transporting in He mechanism minute, closing a floodgate, the quiet end cap force deformation that is hit causes high pressure disjunction failure; This project organization processing and assembling are simple on the other hand, and production cost is low.
Description
Technical field
The utility model relates to the reinforced quiet end cap sealing structure of a kind of high-pressure vacuum switch pipe.
Background technology
There is the yielding problem of quiet end in existing high voltage vacuum switch pipe, the structure of the quiet end of existing vacuum switch tube as shown in Figure 1, on the one hand, compressive resistance is high owing to cut-offfing, and the insulation distance of switching tube is large, and conducting rod is long, weight is large, the deadweight of switching tube itself is also very large, usually causes the quiet end casing distortion of switching tube in the transportation installation process of switching tube, makes the dynamic and static end tube core of switching tube decentraction.On the other hand, while cut-offfing on breaker mechanism due to high voltage vacuum switch pipe, can produce very large impulsive force, cause quiet end casing distortion, make switching tube performance become extremely unstable.
Utility model content
The purpose of this utility model is to provide the reinforced quiet end cap sealing structure of a kind of high-pressure vacuum switch pipe, and while avoiding vacuum switch tube to cut-off in transportation Huo mechanism, quiet end cap produces distortion, guarantees the dynamic usability of vacuum switch and the stability of parameter.
The purpose of this utility model is to be achieved through the following technical solutions:
The reinforced quiet end cap sealing structure of a kind of high-pressure vacuum switch pipe, comprise quiet end casing and sealing ring, described quiet end casing is ring-type, the interior ring edge of quiet end casing and place, outer shroud edge are provided with respectively the straight mouthful flange of interior ring and the straight mouthful flange of outer shroud, described sealing ring middle part is provided with vertebra shape and closes up, port sealing welding of the straight mouthful flange of outer shroud of described quiet end casing and described sealing ring.
Further, the straight mouthful flange of described interior ring is crooked vertically downward, and crooked vertically upward again after the first bending vertically downward of the straight mouthful flange of described outer shroud, the cross section of the straight mouthful flange of outer shroud takes the shape of the letter U.
Further, the straight mouthful flange of described interior ring is crooked vertically downward, and the straight mouthful flange of described outer shroud is crooked vertically upward.
Preferably, the thickness of described quiet end casing is 2.0mm.
The beneficial effects of the utility model are: quiet end casing has the straight mouthful flange of interior ring and the straight mouthful flange of outer shroud, sealing ring are designed to the structure that vertebra shape is closed up, greatly strengthen on the one hand the impact strength of the quiet end cap part of vacuum switch tube, can effectively prevent transportation neutralization minute, quiet end cap is hit power and is out of shape and causes high pressure disjunction failure while closing a floodgate; This project organization processing and assembling are simple on the other hand, and production cost is low.
