Abstract
The utility model belongs to the seal fastening technical field, and discloses a corrosion-resistant seal fastening composite member. The corrosion-resistant seal fastening composite member comprises a bolt, an annular spacer, a spring washer and a nut. A layer of teflon film is covered outside basis materials of the annular spacer, and a layer of teflon film is covered outside basis materials of the spring washer. The thickness of the teflon film can be 0.3 mm to 0.5mm. The basis materials of the annular spacer are carbon steel. The basis materials of the spring washer are spring steel wires. The corrosion-resistant seal fastening composite member is simple in manufacturing technology, low in cost, long in service life, and high in reliability. The strength of seal and fastening is higher than that of congeneric products.
Description
Technical field
The utility model belongs to sealing tightening technology field, particularly a kind of sealing fastening combined piece against corrosion.
Background technique
Mine escape capsule and sea rescue cabin etc. are when assembling, can use number in 1,100 sealing clamping bolt nut, connect inside and outside, cabin and many structural members fixing, because the working environment of rescue capsule is special, require very high to the sealing fastener that uses, rescue capsule is enabled and often is in than in the rugged environment, and extraneous bad air, poison gas, salt fog, seawater etc. can not penetrate in the cabin.Although the sealing clamping bolt nut assembly that uses now can both satisfy the fastening requirement of sealing, these sealing fastener bolt and nuts are easy to oxidized rust corrosion in long-term the use, exist the hidden danger that produces poor sealing, bring inconvenience to repair demolition.The utility model provides the good sealing fastening combined piece of a kind of corrosion resistance, to reach the purpose of energy salt fog resistance, moisture resistant, anti-oxidation not rust corrosion in long-term placement or the use.
Summary of the invention
The purpose of this utility model is in order to remedy the deficiency of existing product, to provide a kind of corrosion resistance good sealing fastening combined piece.
The purpose of this utility model is achieved through the following technical solutions:
A kind of sealing fastening combined piece against corrosion comprises bolt, annular gasket, spring washer and nut, it is characterized in that: the body material of described annular gasket and described spring washer is all coating one deck poly tetrafluoroethylene outward.
Described teflon film thickness can be 0.3 mm-0.5mm.
The body material of described annular gasket is carbon steel.
The body material of described spring washer is Spring Steel Wire.
All spray one deck polytetrafluoroethyldispersion dispersion at the outside thread of bolt and the internal thread place of nut, tighten again, so that be provided with polytetrafluoroethyldispersion dispersion between the internal thread of the outside thread of assembly parts bolt after the assembling and nut, can so that the sealability against corrosion of above-mentioned sealing fastening combined piece against corrosion be further improved.
The beneficial effects of the utility model: the sealing fastening combined piece against corrosion that the utility model provides, preparation process is simple, cost is low, long service life, reliability high, sealing and fastening intensity more are higher than like product.

Embodiment
The following examples can make those skilled in the art more fully understand the utility model, but limit never in any form the utility model.
Embodiment 1
A kind of sealing fastening combined piece against corrosion comprises bolt, annular gasket, spring washer and nut, it is characterized in that: the body material of annular gasket and spring washer is all coating one deck poly tetrafluoroethylene outward.
Described teflon film thickness is 0.5mm.
The body material of described annular gasket is carbon steel.
The body material of described spring washer is Spring Steel Wire.
Referring to accompanying drawing: after being inserted in successively annular gasket and spring washer on the bolt, bolt passes the two member fixed holes that are fixed, and spring washer and annular gasket is enclosed within on the male threaded stub of bolt again, nut is screwed on the bolt tightens at last.
Embodiment 2
On the basis of embodiment's 1 described assembly parts, all spray one deck polytetrafluoroethyldispersion dispersion at the outside thread of bolt and the internal thread place of nut, tighten again, so that be provided with polytetrafluoroethyldispersion dispersion between the internal thread of the outside thread of the assembly parts bolt after the assembling and nut.
The teflon (if any) that sprays on the teflon that the annular gasket of the utility model assembly parts, spring washer coat and the screw thread position has good plasticity and heat resistance, can under 260 ℃ of high temperature, use for a long time, do not change even in boiling water, boil yet, can tolerate the corrosion of all chemicalss, be fabulous barrier coating.The advantage of this model utility is that preparation process is simple, cost is low, long service life, reliability are high, sealing and fastening intensity more are higher than like product.
The above; it only is the better embodiment of the utility model; but protection domain of the present utility model is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the variation that can expect easily or replacement all should be encompassed within the protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claim.
