With the self-sealing joint of the switchgear of model, and it can be easy to open or be closed self-sealing joint, avoid gas leakage, realize zero
Discharge inflation.
Further, the promotion part includes knob, push rod and bellows, and the knob is connect with push rod, described
Push rod be threadedly coupled with bellows, push rod end is pierced by the first connector.Knob is rotated, push rod rotation is driven by knob, is pushed away
Bar is pushed ahead, and the adapter being arranged on the first connector is pushed ahead in push rod end, realizes and self-sealing joint is driven to open.This
Sample avoids other leakages of SF6 and other impurities gas when inflation and enters in switchgear, guarantees sealing.
Further, the main body is equipped with gas chamber, and the promotion part further includes sealing, and described gas chamber one end is set
There is the channel with the first fittings, the other end is slidably connected with sealing, and the bellows is set in gas chamber, push rod end
Across channel to the first connector.The effect of sealing is to guarantee that gas cannot be leaked from knob portion.Guarantee that gas can only be from logical
It is flowed in road.
Further, first inner nosepiece wall is equipped with the protrusion with switching cephalic par cooperation.Protrusion is capable of increasing
Frictional force between adapter makes adapter be not easy to deviate from from the first connector.
Further, second inner nosepiece wall is equipped with sealing ring.By sealing ring can by switchgear from
Sealing joint is closely connect with adapter, is avoided SF6 gas from overflowing in gas replenishment process from the second connector and is revealed.
Further, second connection adapters put down that high connector, ABB connector, Schneider connector, connector is opened in north or Thailand opens
Connector can adapt to different types of self-sealing joint by the present apparatus, easy to use.
Compared with prior art, beneficial effect is:
1, existing connection type can be changed by the present apparatus, different types of from sealing-in on different switchgears
Head, is converted into a type of self-sealing joint, and use is more convenient；
2, the self-styled spool that can be easy to open or be closed by the present apparatus in self-sealing joint, facilitates charge operation；
3, the entrance of the leakage of SF6 gas and foreign gas, avoids pollution environment when the present apparatus can be avoided inflation.
Detailed description of the invention
Fig. 1 is the utility model overall structure diagram.
Specific embodiment
The attached figures are only used for illustrative purposes and cannot be understood as limitating the patent；In order to better illustrate this embodiment, attached
