Summary of the invention
The object of the present invention is to provide a kind of energy removal to remain in the fluid filling valve of the liquid on the conical surface of spool bottom.
For realizing purpose of the present invention, a kind of fluid filling valve, comprise that the side offers the valve seat of charging hole, be arranged on the valve rod of valve seat bottom, the middle part of valve rod offers centre hole, the bottom of valve rod is provided with the spool of a bottom band conical surface, the junction of valve rod and spool is provided with discharging opening, on the valve rod of discharging opening outside, be arranged with the bottleneck positioning seat, the top of valve rod is provided with spring fixed seat, spring is arranged between bottleneck positioning seat and the spring fixed seat, described spool bottom offers a central blind hole, the side of central blind hole offers an air extractor vent that communicates with central blind hole at least, and offers aspirating hole in the corresponding bottleneck positioning seat of at least one air extractor vent of spool side, and the bottleneck positioning seat is provided with seal ring with the contacted inwall of spool and contacts with seal spool.
In order better to realize purpose of the present invention, first kind of technical scheme of the present invention is: described air extractor vent outer valves wicking surface offers the groove of an annular, and this annular groove is corresponding with the aspirating hole in the bottleneck positioning seat.
In order better to realize purpose of the present invention, second kind of technical scheme of the present invention is: described bottleneck positioning seat is provided with the annular groove that communicates with aspirating hole with the contacted inwall of spool, and this annular groove is corresponding with the air extractor vent in the spool.
The invention has the beneficial effects as follows: after air extractor vent, central blind hole were set on the spool, the liquid that utilizes air extractor will remain on the spool taper bottom surface was taken away.

The specific embodiment
Below in conjunction with accompanying drawing, the structure and the principle of work of fluid filling valve of the present invention is described in further detail.
As illustrated in fig. 1 and 2, first kind of technical scheme of the present invention is: a kind of fluid filling valve, comprise that the side offers the valve seat 2 of charging hole 1, be arranged on the valve rod 3 of valve seat 2 bottoms, the middle part of valve rod 3 offers centre hole 4, the bottom of valve rod 3 is provided with the spool 5 of a bottom band conical surface, valve rod 4 is provided with discharging opening 6 with the junction of spool 5, on the valve rod 3 of discharging opening 6 outsides, be arranged with bottleneck positioning seat 7, the top of valve rod 4 is provided with spring fixed seat 8, spring 9 is arranged between bottleneck positioning seat 7 and the spring fixed seat 8, described spool 5 bottoms offer a central blind hole 10, the side of central blind hole 10 offers four air extractor vents 11 that communicate with central blind hole 10, and a plurality of air extractor vents 11 also can be set, and actual quantity can be set as required.Described air extractor vent 11 outside spools 5 surfaces offer an annular groove 12, with offer aspirating hole 13 at least one air extractor vent 11 corresponding bottleneck positioning seats 7 of spool 5 sides, this annular groove 12 is corresponding with the aspirating hole 13 in the bottleneck positioning seat 7, and bottleneck positioning seat 7 is provided with seal ring 14 and spool 5 sealing contacts with spool 5 contacted inwalls.
As shown in Figure 3, second kind of technical scheme of the present invention is: a kind of fluid filling valve, identical with most of structure of first kind of technical scheme, what its difference only was annular groove offers the position difference, be that described bottleneck positioning seat 7 is provided with the annular groove 15 that communicates with aspirating hole 13 with spool 5 contacted inwalls, this annular groove 15 is corresponding with the air extractor vent 11 in the spool 5, and bottleneck positioning seat 7 is provided with seal ring 14 and spool 5 sealing contacts with spool 5 contacted inwalls.
The working process of first kind of technical scheme of the present invention is: bottleneck is close on the bottleneck positioning seat 7, then valve seat 2 is pressed down, spring 9 shrinks, spool 5 enters in the filling bottle under the effect of valve rod 3, discharging opening 6 is communicated with in the centre hole 4 of valve rod 3 and the filling bottle, at this moment the exterior liquid of fluid filling valve enters from charging hole 1, through the centre hole 4 of valve rod 3, after in the discharging opening 6 inflow filling bottles.After can finishes, valve seat 2 resets under the effect of spring 9, and spool 5 shrinks back under the effect of valve rod 3 in the bottleneck positioning seat 7, and discharging opening 6 is thereupon by the inwall bumping post of bottleneck positioning seat 7, the lower end of the centre hole 4 of valve rod 3 can't communicate with the external world, and the liquid that can not in the centre hole 4 flows out.After spool 5 resets fully, start the air extractor that links to each other with aspirating hole 13, the liquid that remains on the spool 5 taper bottom surfaces flows into air extractor vent 11 from central blind hole 10 under the effect of air extractor, taken away from aspirating hole 13 through annular groove 12 backs then.Residual like this liquid will be fallen by complete liquidation, has kept the cleaning of working environment, has reduced some unnecessary work.
The working process of second kind of technical scheme of the present invention and first kind basic identical, in this just no longer detailed introduction.
