Brief description of the drawings
Fig. 1 is the structural representation of rubber seal；
Wherein：1st, inner seal ring；2nd, ring skeleton；3rd, outer side seal circle.
Specific embodiment
With reference to the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Ground description, it is clear that described embodiment is only a part of embodiment of the invention, rather than whole embodiments.It is based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under the premise of creative work is not made
Embodiment, belongs to the scope of protection of the invention.
Many details are elaborated in the following description in order to fully understand the present invention, but the present invention can be with
Other manner described here is different from using other to implement, those skilled in the art can be without prejudice to intension of the present invention
In the case of do similar popularization, therefore the present invention is not limited by following public specific embodiment.
As shown in figure 1, the invention discloses a kind of rubber seal, including the L-shaped ring skeleton 2 of section configuration, bag
Overlay on the layer of silica gel and the inner seal ring 1 and exterior seal ring 3 located at the inner side of ring skeleton 2 in the outside of ring skeleton 2, inner seal ring
1 and exterior seal ring 3 respectively be located at the inner side and outer side of ring skeleton 2；The inner seal circle is to be connected to the inner side of ring skeleton 2
Annular tubular structure, it is integrally formed with the layer of silica gel in the outside of ring skeleton 2, and annular tubular structure inner side is provided with section in isosceles
The bulge loop of triangle, annular tubular structure outside be provided with its integrally formed tightening hoop, tightening hoop is that section is O shapes；
The exterior seal ring 3 is inverted horn-like structure, and horn-like structure is suitable for reading to be integrally formed with layer of silica gel, and intraoral side opens up under it
The airtight groove of annular, inner seal ring is O-ring seal, and the bulge loop of the isosceles triangle that its inner side is set in use can
Be close to rotary shaft, and the effect for being arranged on the tightening hoop on the outside of annular tubular structure be prevent rotary shaft in rotation process because
Beat and gap is produced between inner seal ring, and tightening hoop can remain compression of the annular tubular structure to rotary shaft
Power, it is ensured that sealing property, still further aspect, this is substantially a kind of lip packing using the exterior seal ring in new, its with it is interior
Sealing ring is coaxially disposed, and because it is inverted horn-like structure, coordinates with rotary shaft after installing, and its underpart inner side is adjacent to rotation
Axle, it is ensured that it has the air-tightness of stabilization between rotary shaft.
Because same set of sealing ring should realize oil sealing, sealing gland is also realized, and oil sealing and sealing gland are to quality of rubber materials requirement
Difference, the used quality of rubber materials of oil sealing requirement has high oil resistivity and stability, and sealing gland requires used rubber
Material has good superficiality, and can fit rotary shaft in use, if using different quality of rubber materials respectively as
Inner seal ring and exterior seal ring, then virtually improve the production cost of sealing ring, and needs to be molded several times, production process
More, to avoid drawbacks described above, layer of silica gel, inner seal ring and exterior seal ring in the present invention use integrally formed mode, and
Layer of silica gel, inner seal ring and exterior seal ring are using the raw material of following parts by weight through mixing, clot, bottom sheet, back mixing, vulcanization and two
Section vulcanization molding is formed：Wherein 100 parts of rubber, activating agent 20-25 parts, 5 parts of plasticizer, 3 parts of antiaging agent, 10 parts of reinforcing agent,
1 part of 10 parts of plasticiser, 5 parts of accelerator and vulcanizing agent.
Rubber is nitrile rubber, and activating agent is activator FT and zinc oxide, the wherein weight portion of activator FT and zinc oxide
Number is than being 3：1, plasticizer is dibutyl sebacate, and antiaging agent is octylatcd two amine, and reinforcing agent is nano-calcium carbonate, plasticizing
Agent is dioctyl phthalate, and accelerator is the ratio of weight and number of TMTD and accelerant CZ, Vulcanization accelerator TMTD and accelerant CZ
It is 1：1, vulcanizing agent is sulphur.
In a word, the present invention is respectively provided with inner seal ring and exterior seal ring, inner seal ring by L-shaped skeleton inner side and outer side
Oil sealing is realized, exterior seal ring realizes sealing gland, a set of sealing ring need to be only installed and be capable of achieving two kinds of functions, be easily installed and safeguard,
And equipment cost can be reduced, inner seal ring and exterior seal ring are using the quality of rubber materials with stronger oil resistivity, its surface
Polarity is big, good stability, is difficult swelling, can simultaneously meet oil sealing and sealing gland requirement, facilitates one-shot forming, reduction to be produced into
This.
