Abstract
The utility model relates to an end face sealing device for use. The end face sealing device should be provided on fuse base and comprises a cap cover fixedly connected with the fuse base via threads,a cover board between the end face of the fuse base and the cap cover, an O-shaped rubber seal ring between the fuse base and the cover board, and a handle integrated with the cover board. Compared to common sealing device of fuse, the sealing material of the end face sealing device is more tight, the installment and sealing pressure is adjustable, thereby realizing more effective and reliable sealing performance, to prevent external air, dust, water and the like, and confirm the insulation and safe property of fuse.
Description
Technical field
The utility model relates to a kind of face seals that is used for fuse.
Background technology
Buried case becomes, wind power generation box becomes owing to be installed on bleak and desolate windy and dusty and humid regions such as desert, Gobi desert, coastal waters, nearly river, the fuse that is adopted needs effectively, sealing reliably, to prevent intrusions such as extraneous air, dust, water, guarantee fuse insulation safety performance.And the sealing device of general fuse adopts the fastening cap of threaded rotation to seal by directly contacting with sealing ring mostly, because the turning effort of cap in the fastening process of compression, it is stressed easily to drive the sealing ring rotation, cause that the sealing ring local pressure stretches and compression, cause the sealing ring compression inhomogeneous, seal failure causes fuse potential safety hazard to occur easily.
Summary of the invention
The purpose of this utility model provides a kind of face seals that is used for fuse exactly in order to address the above problem, the sealing device is compared with the sealing device of general fuse, has effective more, reliable sealing performance.
The purpose of this utility model is achieved in that the utility model provides a kind of face seals that is used for fuse, described fuse comprises mounting base and is located at the handle of mounting base end face, described handle has integrated with it cover plate, this cover plate is placed on the end face of mounting base, described sealing device comprises the cap that is connected by screw threads for fastening with described fuse mounting base, and described sealing device also comprises the sealing ring of being located between fuse mounting base and the cover plate.
At the above-mentioned face seals that is used for fuse, the fuse mounting base is provided with the annular groove that is complementary with described O type rubber seal, and described O type rubber seal places in the annular groove.
At the above-mentioned face seals that is used for fuse, O type rubber seal adopts the organic rubber composite material.
At the above-mentioned face seals that is used for fuse, cap is equipped with the gear-like profile.
The utility model is compared with the sealing device of general fuse, and encapsulant is fine and close more, sealing load is installed can be adjusted, and has effective more, reliable sealing performance, prevents intrusions such as extraneous air, dust, water, guarantees fuse insulation safety performance.

Fig. 2 is the left view of Fig. 1.
Embodiment
Referring to Fig. 1, Fig. 2, fuse comprises mounting base 3 and is located at the handle 22 of mounting base 3 end faces, this handle 22 also comprises integrated with it cover plate 21, this cover plate 21 is placed on mounting base 3 end faces, the utility model sealing device is installed on the pedestal of fuse, comprise cap 1 and O RunddichtringO 5, sealing ring 5 fills up between mounting base 3 and cover plate 21, mounting base 3 end faces and sealing ring 5 contact positions, it is recessed poor 4 to be equipped with annular, and sealing ring 5 places in this annular groove 4, and this annular groove 4 has the sealing ring location and increases sealing contact surface, thereby improve the effect of sealing validity, and contact static seal with cover plate 21 end faces; Described cap 1 is placed on the handle 22, be fastenedly connected by the screw thread 31 on the fuse mounting base 3 side peripheries, screw threads for fastening power puts on rubber seal 5 by mounting base 3 and cover plate 21, it is compressed, make rubber seal 5 and mounting base, the tight contact of cover plate end face, reach inside and outside isolating seal effect, with general sealing device be the fastening cap of threaded rotation and the direct contact gear ratio of sealing ring, seal more reliable, because the turning effort of cap in the fastening process of compression, it is stressed easily to drive the sealing ring rotation, causes that the sealing ring local pressure stretches and compression, cause the sealing ring compression inhomogeneous, seal failure.
At the above-mentioned face seals that is used for fuse, cap 1 is equipped with the supplier and just rotates and supply the fastening gear-like profile 6 of round nut wrench, and that described rubber sealing ring 5 adopts is high temperature resistant, oil resistant, ageing-resistant, elastomeric organic rubber composite material are made.
Above embodiment is only for the usefulness that the utility model is described, but not to restriction of the present utility model, person skilled in the relevant technique, under the situation that does not break away from spirit and scope of the present utility model, can also make various conversion or modification, therefore all technical schemes that are equal to also should belong to category of the present utility model, should be limited by each claim.
Claims (4)
