Summary of the invention
The applicant, for the shortcoming in above-mentioned existing production technology, provides a kind of circuit breaker rational in infrastructure Combined vertical dynamic sealing device, thereby has improved sealing reliability.
The technical solution adopted in the present invention is as follows:
A kind of circuit breaker Combined vertical dynamic sealing device, comprise circuit breaker, perforate on the gas tank shrouding of described circuit breaker one end, shown in hole through kinematic link, the outer surface of described kinematic link is by sealing device and hole sealing, the structure of described sealing device is: comprise the sealing axle sleeve being enclosed within on kinematic link, the inner peripheral surface of described sealing axle sleeve and the outer circumference surface of kinematic link are by spaced the second sealing ring and the sealing of the 3rd sealing ring, the inner surface of the outer circumference surface of described sealing axle sleeve and the perforate of gas tank shrouding institute is by the first sealing ring sealing, the outside of described sealing axle sleeve is extended with connector, described connector is fastening by bolt and gas tank shrouding.
Further improvement as technique scheme:
Described the first sealing ring is O RunddichtringO, on the outer circumference surface of described sealing axle sleeve, has groove, and the first sealing ring is installed in described groove;
Described the second sealing ring and the 3rd sealing ring all adopt y-type seal ring, the inner peripheral surface of described sealing axle sleeve has four concave inward structures successively, two the 3rd sealing rings and two the second sealing rings are installed in described concave inward structure successively, and described the 3rd sealing ring and the second sealing ring are symmetrical to be installed.
Beneficial effect of the present invention is as follows:
The present invention is rational in infrastructure, compact, easy for installation, utilize sealing axle sleeve assembly Direct Action Type dynamic sealing technology, adopt respectively by the hermetically-sealed construction of sealing axle sleeve, y-shaped ring, O-ring seals, y-shaped ring II composition, make movable contact of vacuum circuit breaker in rectilinear motion process, can not make the Leakage Gas in aeration tank, ensure the pressure of aeration tank, make the normally operation under pressure of inner electric elements, thereby improved product reliability of operation and useful life.
The present invention is widely used in the industries such as metallurgy, petrochemical industry, mine, development zone, urban track traffic and high building and is subject to high-quality, high request, the high performance C-GIS gas-filling cabinet products such as miniaturization, intellectuality, non-maintaining, full operating mode.
