A kind of air-strainer seal ring?
Technical field
The present invention relates to a kind of seal ring, especially relate to a kind of air-strainer seal ring.
Background technique
At present, the engine air filter seal ring that heavily blocks automobile is arranged between filter element and filter seat mostly, owing to heavily blocking, motor car engine when work power is strong, in addition vehicle significantly jolting under steam, cause seal ring easily to produce between filter element and filter seat loosening, reduce the surface friction drag of seal ring and parts, thereby reduce the sealability of seal ring, shorten the working life of seal ring, affect the normal work of air-strainer, and then affected air inlet quality and the power performance of motor car engine.
Summary of the invention
The object of the invention is in use easily to produce for the seal ring between existing filter element and filter seat loosening, cause the poor problem of sealing effect, the air-strainer seal ring of a kind of simple in structure, good sealing effect, long service life is provided.
The present invention solves the technological scheme that its technical problem takes:
A kind of air-strainer seal ring, comprise diaphragm seal, seal, stiffening rib and supercharging tongue, it is characterized in that: described diaphragm seal is set to cirque structure, described seal is set to cirque structure, and be connected with diaphragm seal, described stiffening rib is arranged on seal, stiffening rib not only can improve the performance of seal ring, also can improve the tightness between seal ring and parts, described supercharging tongue is arranged on seal, supercharging tongue can increase the resistance between seal ring and parts, and then improve the sealing of seal ring, make seal ring be difficult for producing loosening, described diaphragm seal, seal, stiffening rib, the supercharging tongue structure that is formed in one, can improve the overall performance of seal ring, extend the working life of seal ring.
Described diaphragm seal, its internal diameter is 100-102mm, external diameter is 120-122mm.
Described stiffening rib, its quantity is 1-3 bar.
Described supercharging tongue, its quantity is 3-6, is evenly distributed on seal.
Beneficial effect: the present invention is provided with multiple stiffening ribs and supercharging tongue on the seal of air-strainer seal ring, stiffening rib can improve the structural behaviour of seal ring, can improve again the tightness between seal ring and filter cleaner, make seal ring in use be difficult for producing loosening, simultaneously, supercharging tongue is set and can on filter cleaner, increases surface friction drag, extend the working life of seal ring, improve the sealing of seal ring, ensure the normal work of air-strainer, and then air inlet requirement while having guaranteed vehicle motor work.

Embodiment
Below with reference to accompanying drawing, the present invention is described in detail.
A kind of air-strainer seal ring, comprise diaphragm seal 1, seal 2, stiffening rib 3 and supercharging tongue 4, it is characterized in that: described diaphragm seal 1 is set to cirque structure, its internal diameter is 100mm, external diameter is 120mm, described seal 2 is set to cirque structure, and be connected with diaphragm seal 1, described stiffening rib 3 is arranged on seal 2, its quantity is 2, stiffening rib 3 not only can improve the performance of seal ring, also can improve the tightness between seal ring and parts, described supercharging tongue 4 is arranged on seal 2, its quantity is 4, be evenly distributed on seal 2, supercharging tongue 4 can increase the resistance between seal ring and parts, and then improve the sealing of seal ring, make seal ring be difficult for producing loosening, described diaphragm seal 1, seal 2, stiffening rib 3, supercharging tongue 4 structure that is formed in one, can improve the overall performance of seal ring, extend the working life of seal ring.
The part that the present invention does not relate to all prior art that maybe can adopt same as the prior art is realized.
