As background technique is introduced, carry out gas leakage to block being a kind of method rapidly and efficiently using adhesive.
However carrying out SF6During gas blocks, since macromolecular adhesive is required to certain curing time, if for leak source
It is directly bonded with adhesive, will lead to and fail since adhesive strength is insufficient, in view of the above-mentioned problems, present applicant proposes one kind
Transformer equipment SF6Gas permeation plugging device.
In a kind of exemplary embodiment of the application, as Figure 1-10 shows, a kind of transformer equipment SF6Gas permeation blocks dress
It sets, including the nut, protection nut and closing bolt being used cooperatively, the nut has using with closing through upper and lower end face
The outer circumference surface of the internal thread hole 4 that bolt matches, the nut top has external thread structure 3, and the protection nut has
The internal thread structure to match with the external thread structure, the protection nut are equipped with venthole.
The nut includes the cylinder segment structure 1 and frustum of a cone segment structure 2 of integral type, the excircle of the cylinder segment structure
Surface top has the external thread structure 3, and the side original conical surface and bottom surface angle α angle of the frustum of a cone segment structure are 30 °.
The protection nut includes sealing cover 5 and is fixed on sealing cover edge and perpendicular connection side wall 6, the company
The inside for connecing side wall has the internal thread structure 7 to match with the external thread structure.
The middle part of sealing cover is arranged in the venthole 8, and the venthole runs through the upper and lower end face of sealing cover.
The closing bolt includes nuts 9 and spiral shell that is connecting with nuts integral type and matching with internal thread hole
Rasp bar 10.
The plugging device of the utility model is in use, first by the internal thread structure on the connection side wall for protecting nut
It is tightened on the external thread structure of cylinder segment structure of nut, i.e., assembles protection nut with nut, the spiral shell that will be assembled
Female and protection nut pastes the gas leak source in transformer equipment using adhesive, specifically, in the frustum of a cone segment structure of nut
Bottom surface coats a small amount of adhesive, and the circular conical surface of frustum of a cone segment structure coats adhesive, on the external peripheral surface of cylinder segment structure not
Adhesive is coated with the part of protection nut cooperation, nut is fixed on gas leak source using adhesive, due to frustum of a cone section
Bottom surface coats a small amount of adhesive, and adhesive will not enter internal thread hole below internal thread hole, due to protecting the effect of nut, glue
