Abstract
The utility model discloses a kind of double-sealing device of seal case, including the tank wall of seal case, sealed platform cover, it is characterised in that：Include cover plate, internal layer back-up ring and outer layer back-up ring on the sealed platform cover, the internal layer back-up ring and outer layer back-up ring block internal layer sealing strip and outer layer sealing strip respectively spacingly, the tank wall top of the seal case is arranged respectively to relative " L " shape, and the internal layer sealing strip mutually coincide with outer layer sealing strip when sealed platform cover closes in " L " the shape top of inverted "L" shaped and the tank wall.Wherein internal layer sealing strip is stuck on the vertical line of " L " shape, and outer layer sealing strip is withstood on the horizontal line of " L " shape, plays the effect of dual-seal.Using the sealing device of this structure, advantages of simple is designed, processing cost is low, has dual-seal performance and can increase the time of the sealing term of validity, reduces the seal failure caused by processing factors, environmental factor.
Description
Technical field
It the utility model is related to sealing device field, more particularly to a kind of double-sealing device of seal case.
Background technology
At present the sealed platform cover of conventional seals casing mainly by single sealing strip compress sealing, but production and processing due to
, easily there is poor sealing situation in respective location in deformation, the out-of-flatness on case lid and case edge., can only in order to reduce such phenomenon
The fastening force of case lid and case between is increased, increases sealing round bar deflection, can so make seal that plastic deformation, elastic force occur
Disappear, the life-span drastically shortens, to winter temperature step-down particularly after summer high-temperature, due to seal expand with heat and contract with cold and bullet
Property disappearance decrease can cause sealing property to weaken.
Utility model content
In view of the above-mentioned problems, the utility model provides a kind of sealing dress of seal case with dual-seal guarantee
Put.Its is reasonable in design, and the sealing strip of two kinds of unlike materials, different compress modes is sealed for case lid simultaneously, both reduced
Case lid difficulty of processing, strengthen case lid sealing property, sealing term of validity length again.
In order to solve the above technical problems, technical scheme is used by the utility model：A kind of seal case it is dual close
Seal apparatus, including the tank wall of seal case, sealed platform cover, it is characterised in that：Include cover plate, internal layer back-up ring on the sealed platform cover
With outer layer back-up ring, the internal layer back-up ring and outer layer back-up ring block internal layer sealing strip and outer layer sealing strip respectively spacingly, described close
The tank wall top of joint sealing body is arranged respectively to relative " L " shape, and the internal layer sealing strip closes with outer layer sealing strip in sealed platform cover
When mutually coincide in " L " the shape top of inverted "L" shaped and the tank wall.Wherein internal layer sealing strip is stuck on the vertical line of " L " shape, outer layer
Sealing strip is withstood on the horizontal line of " L " shape, plays the effect of dual-seal.
Further, the degree of protection of the sealed platform cover is IP68 levels, and the ability to bear of seal case can be made stronger, special
The sealing of buried equipment is not applied to.
Further, the internal layer sealing strip and outer layer sealing strip are ethylene propylene diene rubber, silicon rubber, polyurethane rubber respectively
Different one kind in glue, neoprene, using two kinds of unlike material sealing strips, play the effect of complementation.
Further, reinforcement is provided below in " L " the shape top of the tank wall, improves the ability to bear of casing.
From the above-mentioned description to the utility model structure, compared to the prior art, the utility model has following excellent
Point：Apparatus structure is reasonable in design, and processing cost is low, has dual-seal performance and can increase the time of the sealing term of validity,
Reduce the seal failure caused by processing factors, environmental factor.
