Service life.
Further advantage, target and feature of the present utility model embody part by following explanation, and part will also pass through
Research of the present utility model and practice are understood by the person skilled in the art.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the structural representation of vent board in the utility model；
Fig. 3 is that the utility model check valve has the fashionable view of compressed air stream.
Embodiment
In order that technological means, creation characteristic, reached purpose that the utility model is realized more understand and are easy to acting on
Understand, the utility model is further elaborated with reference to the accompanying drawings and detailed description：
As shown in Figure 1-Figure 3, the utility model proposes a kind of check valve for air compressor machine pipe-line system, including valve body
10, the valve body 10 has air inlet 11 and gas outlet 12, has valve pocket 13 in valve body 10, the end of gas outlet 12 is provided with logical
Gas plate 14, the vent board 14 covers whole gas outlet 12, and passage 15 is provided with vent board 14；The air inlet 11 is
Towards the diminishing horn-like cavity in the cross section of gas outlet 12, and there is hemisphere at the bore minimum of the air inlet 11
Shape cavity 16；The supporting plate 17 parallel with the vent board 14 is provided with the valve pocket 13, is offered in the supporting plate 17
Passage, limit spring 18 is fixedly connected with the supporting plate 17, the other end of limit spring 18 is connected with ball sealer 19, institute
Ball sealer 19 is stated to be located in the hemi-spherical cavities 16；The distance between the supporting plate 17 and described hemi-spherical cavities 16 cause
After ball sealer 19 fills up the hemi-spherical cavities 16, the limit spring 18 is in compressive state.
Such scheme coordinates hemi-spherical cavities 16 to realize the unidirectionally controlled of valve by using ball sealer 19, and using limit
Position spring 18 is that ball sealer 19 provides sealed motive force, simple and reliable for structure, ensure that the reliability of check valve；This other practicality is new
Type is provided with supporting plate 17 in valve pocket 13, and supporting plate 17 not only acts as the effect that support force is provided for limit spring 18, also risen
To the effect of buffer compression air-impingement, when compressed air passes through from positioned at the vent board 14 of gas outlet again after supporting plate
When, the impact to the upper vent hole 15 of vent board 14 is reduced, the service life of vent board 14 can be extended；List of the present utility model
To valve in working condition, compressed air enters from air inlet 11, compression seal ball 19, when compression-expansion power is more than limit spring
During 18 elastic force, direction from ball sealer to gas outlet 12 move, compressed air enter valve pocket 13 and flow further through check valve from
Gas outlet 12 is flowed out, when no compressed air enters air inlet 11, ball sealer 19 by limit spring 18 elastic force to air inlet
The movement of 11 directions of mouth, when ball sealer is fully filled with hemi-spherical cavities 16, stops movement, now realize closing function, i.e. valve pocket
Compressed air in 13 can not be back to air inlet 11, unidirectionally controlled so as to realize.
Preferably, based on such scheme, as shown in Fig. 2 with place vent board 14 or place supporting plate 17
Center line is several arcuate sockets of center of circle arrangement, and these arcuate sockets are in a-circle-by-a-circle annular spread with the center of circle.It is existing
Vent board using round vent, because round vent is densely distributed, when in use, round vent due to it is long when
Between impacted by compressed air, easily there is fatigue break, into causing vent board to destroy, by the structure of arcuate socket, add
Big breathing area so that can be bigger from the amount of the compressed air that vent board flows through in the unit interval, so that valve pocket 13
Interior pressure is smaller, therefore impact of the compressed air to vent board reduces, and so as to improve the service life of vent board, and then improves
The service life of check valve.
Preferably, the limit spring 18 has more, and the air inlet 11 relative to valve body 10 and the institute of gas outlet 12
Axis be uniformly distributed.This way it is ensured that limit spring 18 is uniform enough to the elastic force of ball sealer 19, ball sealer 19 is avoided
Deviation, which occurs, in movement locus causes ball sealer 19 to be fully sealed with hemi-spherical cavities 16, influences the using effect of valve.
Preferably, the periphery of limit spring 18 is additionally provided with righting pipe 20, and the righting pipe 20 is fixedly connected on institute
It is to provide protective effect for limit spring 18 to state in supporting plate 17 and set the purpose of righting pipe 20, when limit spring 18 is when long
Between using there is elastic force decrease when, righting pipe 20 can be limit spring 18 laterally supporting power is provided, avoid spring occur it is larger
The bending of angle, and influence the sealing effectiveness of ball sealer 19 and hemi-spherical cavities 16.
Preferably, limited ring dais 21 are additionally provided with the outer surface of valve body 10.The effect of limited ring dais is in valve
During installation, it is easy to quickly be connected with pipeline, air inlet 11 and gas outlet 12 can be inserted in pipeline respectively, and in limited ring dais
Under 21 position-limiting action, quick aligning.
Preferably, the ball sealer is hollow ball, and ball sealer 19 is arranged into hollow ball can reduce limit spring 18
Burden, the gravity of ball sealer 19 reduces, and can extend the service life of limit spring 18.
Finally illustrate, above example is only unrestricted to illustrate the technical solution of the utility model, although ginseng
The utility model is described in detail according to preferred embodiment, it will be understood by those within the art that, can be to this
The technical scheme of utility model is modified or equivalent substitution, without departing from the objective and model of technical solutions of the utility model
Enclose, it all should cover among right of the present utility model.
