Abstract
The utility model discloses a directly-operated type sealing device for a vacuum circuit breaker. The device comprises a piston support and a piston spliced in the piston support, wherein, a suiting hole matched with the piston clearance in a splicing manner is formed on the piston support, an annular step is arranged in the piston support at one end of the suiting hole, a locking part sleeved on the piston and matched with the piston support in a detachable manner is sealed at the other end of the suiting hole, and a disc spring sleeved on the piston and a V-shaped sealing ring pressed through the disc spring and closely matched with the piston are arranged between the locking part and the annular step. Since the adopted V-shaped sealing ring can deform under the pressure of the disc spring, the sealing closeness between the V-shaped sealing ring and the piston is enhanced, the service life is prolonged, the volume of the directly-operated type sealing device is reduced due to the arrangement of the disc spring, and the utilization ratio of the space is improved.
Description
Technical field
The utility model relates to a kind of vacuum circuit-breaker sealing device, especially a kind of vacuum circuit-breaker translation seal device.
Background technology
At present, what the hermetic seal of vacuum circuit-breaker design was adopted is rotational sealing structure, as shown in Figure 1, is connected with connecting lever 24 in the bottom of the insulated tension pole 21 of vacuum circuit-breaker, be connected with rotation axis 26 on the connecting lever 24, rotation axis 26 is sealed on the connecting lever box 27 by sealing ring 22.By rotation rotation axis 26 insulated tension pole 21 is moved up and down during use and realize the divide-shut brake of vacuum circuit-breaker.This hermetically-sealed construction its internal structure in use is invisible, regulates and open apart from measuring operation and make troubles for the contacts for vacuum-break switches closing rebound, and dismounting is also inconvenient during maintenance, has reduced the efficient of work.
The utility model content
The purpose of this utility model provides a kind of vacuum circuit-breaker translation seal device, to reduce production costs, increases work efficiency.
In order to realize above purpose, the technical scheme that the utility model adopted is: a kind of vacuum circuit-breaker translation seal device, this device comprises piston seat and the piston that is inserted in the piston seat, piston seat is provided with the suit hole that cooperates with the piston clearance sleeve, in the piston seat of suit hole one end, be provided with ring-shaped step, the other end in suit hole be closed be sleeved on the piston and with the locking member that piston seat detachably cooperates, between locking member and ring-shaped step, be provided with the dish spring that is sleeved on the piston and by disc spring pressing with the close-fitting v-ring of piston.
On the upper and lower end face of described v-ring, be respectively arranged with the support ring that is sleeved on the piston, on the upper and lower end face of described dish spring, be respectively arranged with the supporting bracket that is sleeved on the piston, described support ring, v-ring and supporting bracket by disc spring pressing between described locking member and ring-shaped step.
Tight double team has the dustproof full skirt that is sleeved on the piston between the both ends of the surface about described locking member, and described dustproof full skirt and piston closely cooperate.
Described dustproof full skirt is to be made of with ring ladder on being connected annular shirt rim annular shirt rim, and described annular shirt rim is provided with towards the ring-shaped step direction.
Described locking member one end is provided with annular boss, and the external diameter of described annular boss is greater than the internal diameter in suit hole, and the annular boss of described locking member spins to cooperate by screw thread and piston seat and fixes.
Because the translation seal device that the utility model adopts, compare rotary seal and saved the connecting lever box, raw material have been saved, reduced production cost, save the connecting lever box simultaneously and make its internal structure high-visible later on, can carry out the contacts for vacuum-break switches closing rebound easily and regulate and open, avoided using rotary seal when maintenance, need dismantle the step of connecting lever box apart from operations such as measurements, increase product reliability, improved the efficient of work.Secondly, the v-ring of employing can be out of shape under the pressure of dish spring, thus increased and piston between the tightness degree and the useful life that seal, and the setting of dish spring dwindled the volume of translation seal, improved utilization of space.
In addition, because the removable support that the utility model adopts, the piston in the assembly and disassembly translation seal device, dish spring and seals and other component have improved assembling and maintenance efficiency more easily.
In addition, because the utility model adopts the double team structure of dustproof full skirt, the volume of translation seal device is dwindled greatly, for vacuum circuit-breaker has been saved the space.
