Abstract
A kind of one-way valve, comprise valve body, spool, valve body entrance point, valve outlet end, block and stop ledge, described block is placed in valve inner, near valve body entrance point, is equipped with spool, is equipped with discharge orifice between described valve body entrance point and spool inside block; Be equipped with Returnning spring on rear side of described spool, described Returnning spring is connected with stop ledge.The beneficial effects of the utility model are, the utility model is provided with discharge orifice, when flow is excessive again, can reduces pressure timely, be equipped with Returnning spring simultaneously, can reset timely, be equipped with flow transducer at valve outlet end, monitor flow timely, by Single-chip Controlling discharge orifice, prevent flow excessive, cause shorten the working life of valve.
Description
Technical field
The utility model relates to a kind of one-way valve.
Background technique
Traditional one-way valve, be applied in hydraulic pipe line or other situations are all generally unidirectional keying valves for preventing flowing medium adverse current on all kinds of pipeline or equipment, when entering from the fluid in a direction, one-way valve is through, and when entering from other direction, one-way valve closes.But when flow is excessive, excessive to the pressure of spool, cause the shortening in working life, even cause the inefficacy of valve.
Model utility content
For the deficiencies in the prior art, the utility model provides a kind of one-way valve, long service life, and sealing is better, can have restriction simultaneously, can effectively reduce pressure to uninterrupted.
For solving the problems of the technologies described above, the technical solution of the utility model is, a kind of one-way valve, comprise valve body, spool, valve body entrance point, valve outlet end, block and stop ledge, described block is placed in valve inner, near valve body entrance point, be equipped with spool inside block, between described valve body entrance point and spool, be equipped with discharge orifice; Be equipped with Returnning spring on rear side of described spool, described Returnning spring is connected with stop ledge.
Further, described valve outlet end is equipped with flow transducer, and it is electrically connected with single-chip microcomputer.
Further, described discharge orifice place is equipped with solenoid electric valve, and is electrically connected with single-chip microcomputer.
Further, seal ring is equipped with between described block and spool.
Further, described discharge orifice is set to two, and correspondence is equipped with two solenoid electric valves.
The beneficial effects of the utility model are, the utility model is provided with discharge orifice, when flow is excessive again, can reduces pressure timely, be equipped with Returnning spring simultaneously, can reset timely, be equipped with flow transducer at valve outlet end, monitor flow timely, by Single-chip Controlling discharge orifice, prevent flow excessive, cause shorten the working life of valve.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the utility model embodiment SCM system control graph.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in more detail;
As Fig. 1, shown in 2, a kind of one-way valve, comprise valve body 1, spool 2, valve body entrance point 3, valve outlet end 4, block 5 and stop ledge 6, it is inner that described block 5 is placed in valve body 1, near valve body entrance point 3, be equipped with spool 2 inside block 5, between described valve body entrance point 3 and spool 2, be equipped with discharge orifice 7; Be equipped with Returnning spring 8 on rear side of described spool 2, described Returnning spring 8 is connected with stop ledge 6.Further, described valve outlet end 4 is equipped with flow transducer 9, and it is electrically connected with single-chip microcomputer 10.Further, described discharge orifice 7 place is equipped with solenoid electric valve 11, and is electrically connected with single-chip microcomputer 10.Further, seal ring 12 is equipped with between described block 5 and spool 2.Further, described discharge orifice 7 is set to two, and correspondence is equipped with two solenoid electric valves 11.
The utility model can prevent flow excessive effectively, causes the pressure of valve excessive, and then the situation causing life of valve to shorten.When operating, the flow entering valve body entrance point is excessive, and the flow transducer being positioned at valve outlet end detects timely, and information is passed to single-chip microcomputer, and Single-chip Controlling is arranged on the solenoid electric valve at discharge orifice place, opens discharge orifice, timely release pressure.In valve body, be provided with stop ledge simultaneously, also further limit the openings of sizes of spool, limit flow.Therefore, can not flow be there is excessive, cause the phenomenon of valve shortening in working life.
Certainly, above-mentioned explanation is not to restriction of the present utility model, and the utility model is also not limited to above-mentioned citing; those skilled in the art; in essential scope of the present utility model, the change made, change, interpolation or replacement, all should belong to protection domain of the present utility model.
