Description
Technical field
The utility model relates to a kind of Novel diversion valve.
Background technique
The effect of diverter valve is to make to supply identical flow (equivalent shunting) by same oil sources to more than two executive component in hydraulic system, or by a certain percentage to two executive component supply flows (proportional diverting), keep synchronously or surely than relation with the speed that realizes two executive components.
The diverter valve of its moderate shunting, oil sources entrance directly communicates with the meter in mouth of two spools, this kind of structure, when two oil outlets equivalent whens shunting, spool can regulate two oil outlets by movement, keep equivalent shunting, but obvious, hysteresis quality is larger, regulate slow, in the process regulating, unrealized equivalent shunting, affects using effect.
Model utility content
For the problems referred to above, the utility model provides a kind of Novel diversion valve, reduces the adjusting time, maintains good equivalent shunting, further, facilitates staff to examine the working state of diverter valve.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the utility model is achieved through the following technical solutions:
A kind of Novel diversion valve, comprise the valve body in outside, described valve body bottom centre is provided with the oil sources interface communicating with oil sources, in described valve body, be provided with left spool and right spool, between left spool, right spool and valve body, be respectively arranged with left valve pocket and right valve pocket, it is characterized in that, in described oil sources interface, be provided with filter membrane, the described filter membrane left and right sides is provided with the opening of formed objects, the both sides of described filter membrane communicate with the meter in mouth of left spool and right spool respectively, on described left spool, be provided with left oil outlet, on described right spool, be provided with right oil outlet.
First oil sources is shunted through the preliminary equivalent of filter membrane, then flow into respectively the meter in mouth of left spool and the meter in mouth of right spool, then flow into respectively two oil hydraulic cylinders or motor through left oil outlet and right oil outlet again, because the opening of filter membrane both sides is identical with the resistance of the liquid of two meter in mouths, so oil sources can flow out with identical flow after diverter valve.In the time there is imbalance in the flow of any side, the pressure of oil outlet will there will be imbalance, and then cause the pressure reduction imbalance of two meter in mouths, two spools there will be mobile to reduce pressure reduction, and then regulate oil sources equivalent to flow out, wherein, because the preliminary equivalent through filter membrane separates, this error can be smaller, reduce the adjusting time, maintain good equivalent shunting.
Further, on left oil outlet, be provided with left flowmeter, on right oil outlet, be provided with right flowmeter.Facilitate staff to examine the working state of diverter valve.
The beneficial effects of the utility model are: reduce the adjusting time, maintain good equivalent shunting, further, facilitate staff to examine the working state of diverter valve.
Brief description of the drawings
Fig. 1 is the structural representation of a kind of Novel diversion valve of the utility model;
The mark implication of accompanying drawing is as follows:
1: oil sources interface; 2: filter membrane; 3: left meter in mouth; 4: left valve pocket; 5: left flowmeter; 6: left oil outlet; 7: left spool; 8: right meter in mouth; 9: right spool; 10: right flowmeter; 11: right oil outlet; 12: right valve pocket; 13: valve body.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment, technical solutions of the utility model are described in further detail, so that those skilled in the art can better understand the utility model being implemented, but illustrated embodiment is not as to restriction of the present utility model.
As shown in Figure 1, a kind of Novel diversion valve, the valve body 13 outside comprising, for convenience of description, only carries out the description of all parts relation with direction in scheming.
Described valve body 13 bottom centre are provided with the oil sources interface 1 communicating with oil sources, in described valve body 13, be provided with two identical spools, the left spool 7 and the right spool 9 that is positioned at right side that are positioned at left side, spool is valve body 13 is realized the fundamental function of direction control, pressure control or flow control valve part by its movement.Between left spool 7, right spool 9 and valve body 13, be respectively arranged with left valve pocket 4 and right valve pocket 12.
In wherein said oil sources interface 1, be provided with filter membrane 2, preferably the thickness of filter membrane 2 is between 200-1000 micron, described filter membrane 2 left and right sides are provided with the opening of formed objects, preferably filter membrane 2 left and right sides are evenly provided with several openings, filter membrane 2 centres are with left spool 7 and right spool 9 intersections are corresponding and filter membrane 2 centres are solid constructions, be to stop oil to pass through in the middle of filter membrane 2, only filter membrane 2 both sides can allow oil pass through.
The left side of filter membrane 2 communicates with the meter in mouth of left spool 7, right side communicates with the meter in mouth of right spool 9, for the ease of distinguishing, and can be by the left meter in mouth 3 of meter in mouth called after of left spool 7, corresponding, the right meter in mouth 8 of meter in mouth called after of right spool 9.On left spool 7, be provided with left oil outlet 6, on described right spool 9, be provided with right oil outlet 11.
First oil sources is shunted through the preliminary equivalent of filter membrane 2, then flow into respectively left meter in mouth 3 and right meter in mouth 8, then flow into respectively two oil hydraulic cylinders or motor through left oil outlet 6 and right oil outlet 11 again, because the opening of filter membrane 2 both sides is identical with the resistance of the liquid of two meter in mouths, so oil sources can flow out with identical flow after diverter valve.In the time there is imbalance in the flow of any side, the pressure of oil outlet will there will be imbalance, and then cause the pressure reduction imbalance of two meter in mouths, two spools there will be mobile to reduce pressure reduction, and then regulate oil sources equivalent to flow out, wherein, because the preliminary equivalent through filter membrane 2 separates, this error can be smaller, reduce the adjusting time, maintain good equivalent shunting.Consider that oil sources entrance possible speed is more anxious, therefore can be provided with wire netting (not shown) at filter membrane 2 back sides, should be noted, the mesh of wire netting need be corresponding with the opening of filter membrane 2, wire netting can not stop entering of oil sources, otherwise affects the effect of equivalent shunting.
Can also on left oil outlet 6, be provided with left flowmeter 5, on right oil outlet 11, be provided with right flowmeter 10, facilitate staff to examine the working state of diverter valve.
These are only preferred embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure or conversion of equivalent flow process that utilizes the utility model specification and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
