Description
Technical field
The utility model is related to technical field of sealing technology, and in particular to a kind of tetrafluoro carbonization compound seal packing ring structure changes
Enter technology.
Background technology
Tetrafluoro carbonization packing, also known as tetrafluoro packing, it is woven by the woven equipment of pure polytetrafluoroethylene fibre,
Handled without PTFE emulsion and lubricant grease.Because being that there is flexible adjustability by solid braiding, so and axle, stuffing box can be very
The good decay resistance for being combined with brilliance, good self lubricity and anti-paste property.Available for chemical industry, food, medicine, make
Paper, chemical fibre, fine chemistry industry etc. are not allow for the operation of pollution.Polytetrafluoroethylene (PTFE) weaves（Dipping）Packing is woven（Dipping）
Sizing is formed, and good with good chemical stability, self-lubricating property, intensity is constant under high temperature and wet environment, easily filling
And dismounting.
Chinese patent CN202073521U discloses a kind of Self-sealing packing, and the Self-sealing packing of the patent includes packing
A circle rubber banding set is also arranged with outside ring, described packing ring.When packing produces abrasion, rubber banding set is by packing hoop
Tightly, even if packing ring produces abrasion and can still make to keep sealing between packing ring and rod member, therefore the use longevity of packing can be extended
Life.
But, there is elasticity deficiency, insufficient strength, flimsy problem in the Self-sealing packing of above-mentioned patent.
The content of the invention
The utility model provides a kind of tetrafluoro carbonization compound seal packing, and the utility model solves existing tetrafluoro carbonization
There is elasticity deficiency, insufficient strength, flimsy problem in packing product.
To solve the above problems, the utility model is adopted the following technical scheme that：Tetrafluoro carbonization compound seal packing, including four
Fluorine carbonization packing body, glass fibre ring and rubber ring；Tetrafluoro carbonization packing body is in annular, tetrafluoro carbonization packing body
Portion is embedded with glass fibre ring and rubber ring, and glass fibre ring is arranged on the outside of rubber ring；Between glass fibre ring and rubber ring
Contact surface be waveform, contact between glass fibre ring and rubber ring well.
Advantage of the present utility model：Glass fibre ring and rubber are embedded with using the tetrafluoro carbonization packing body interior in annular
The composite construction of glue ring, glass fibre ring substantially increases the intensity of packing, and rubber ring adds the elasticity of packing, makes packing whole
Body is hardly damaged, service life extension；Glass fibre ring and rubber ring use corrugated contact surface, and both, which contact, is well difficult
Separation, improves the overall intensity of packing ring.
Brief description of the drawings
Fig. 1 is the utility model stereogram；
Fig. 2 is the utility model front view；
Fig. 3 is the A-A cutaway view Amplified images in Fig. 2.
Symbol description in figure：Tetrafluoro carbonization packing body 1, glass fibre ring 2, rubber ring 3.
Embodiment
The utility model is described in detail with optimal embodiment below.
As Figure 1-3, tetrafluoro carbonization compound seal packing, including tetrafluoro carbonization packing body 1, the and of glass fibre ring 2
Rubber ring 3；Tetrafluoro carbonization packing body 1 is annular, and tetrafluoro carbonization packing body 1 has been internally embedded glass fibre ring 2 and rubber
Glue ring 3, glass fibre ring 2 is arranged at the outside of rubber ring 3；Contact surface between glass fibre ring 2 and rubber ring 3 is waveform,
Contact good between glass fibre ring 2 and rubber ring 3.
Glass fibre used increases with its diameter its intensity that diminishes, and has following spy as the glass fibre of supporting material
Point, these features make the use of glass fibre come extensively far beyond other fibre types.The characteristics of glass fibre：(1) stretch strong
Degree is high, extends small (3%).(2) coefficient of elasticity is high, and rigidity is good.(3) elongation is big in elastic limit and tensile strength is high, therefore absorbs
Impact energy is big.(4) it is inorfil, has noninflammability, chemical resistance is good.(5) water imbibition is small.(6) processability is good, can be made
Stock, beam, felt, the product for the different shape such as weave cotton cloth.
Finally it should be noted that：Obviously, above-described embodiment is only intended to clearly illustrate the utility model example,
And the not restriction to embodiment.For those of ordinary skill in the field, may be used also on the basis of the above description
To make other changes in different forms.There is no necessity and possibility to exhaust all the enbodiments.And thus
Among the obvious changes or variations amplified out is still in protection domain of the present utility model.
