Description
Technical field
The utility model relates to a kind of sealing material, be specifically related to a kind of sealing material.
Background technique
Teflon (PTFE) seal ring of high functional plastics or make " general spy's envelope " iron-clad outside framework oil seal be introduced into use as far back as the 1970's.Its objective is the blank in order to fill up between conventional rubber seal ring and mechanical seal ring.Extreme temperature, corrosive medium, high surface velocity, high pressure and the environment lacking lubrication etc. harsh force artificer to adopt price higher and the mechanical seal ring of complexity, our " general spy envelope " product is under same harsh environment, its performance has had great improvement than artificial rubber seal ring, and the sealing of price relative mechanical is lower.
It is short all to there is working life in existing sealing material, yielding shortcoming under high temperature.
Model utility content
For the deficiency that prior art exists, the utility model object is to provide a kind of sealing material, not yielding, practical under high temperature.
To achieve these goals, the utility model realizes by the following technical solutions: sealing material, comprise zinc oxide valve plate, synthetic rubber cushion pad, high-strength insulating sleeve pipe, positioning bolt, PVF layer, synthetic rubber external insulation layer and stainless steel cover, zinc oxide valve plate outer installment has high-strength insulating sleeve pipe, synthetic rubber cushion pad is filled with between zinc oxide valve plate and high-strength insulating sleeve pipe, high-strength insulating jacket exterior is provided with synthetic rubber external insulation layer, zinc oxide valve plate two ends are provided with PVF layer, positioning bolt is provided with between PVF layer and high-strength insulating sleeve pipe, PVF layer outer end is provided with stainless steel cover.
As preferably, described high-strength insulating sleeve pipe is provided with pressure relief opening.
As preferably, described PVF layer is provided with bolt hole.
Not yielding, practical under the utility model high temperature.
Accompanying drawing explanation
The utility model is described in detail below in conjunction with the drawings and specific embodiments;
Fig. 1 is structural representation of the present utility model.
Embodiment
The technological means realized for making the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with embodiment, setting forth the utility model further.
With reference to Fig. 1, this embodiment is by the following technical solutions: sealing material, comprise zinc oxide valve plate 1, synthetic rubber cushion pad 2, high-strength insulating sleeve pipe 4, positioning bolt 5, PVF layer 6, synthetic rubber external insulation layer 3 and stainless steel cover 8, zinc oxide valve plate 1 outer installment has high-strength insulating sleeve pipe 4, synthetic rubber cushion pad 2 is filled with between zinc oxide valve plate 1 and high-strength insulating sleeve pipe 4, high-strength insulating sleeve pipe 4 outer installment has synthetic rubber external insulation layer 3, zinc oxide valve plate 1 two ends are provided with PVF layer 6, positioning bolt 5 is provided with between PVF layer 6 and high-strength insulating sleeve pipe 4, PVF layer 6 outer end is provided with stainless steel cover 8.
It should be noted that and described high-strength insulating sleeve pipe 4 is provided with pressure relief opening, prevent zinc oxide valve plate 1 from operationally producing pressure excessive.
In addition, described PVF layer 6 is provided with bolt hole 7.
The electrical properties of the zinc oxide valve plate of this embodiment is better, high-strength insulating sleeve pipe 4 can bear required moment of flexure and torsion, to ensure that when stressed structure is not damaged and performance is constant, and relative rotation can not be there is when being subject to torsion with between sleeve pipe, not yielding, practical under high temperature.
More than show and describe basic principle of the present utility model and major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
