Abstract

The utility model discloses an electrohydraulic reversing valve which comprises an electromagnetic reversing valve, a valve body, an end cover and a valve core, wherein the electromagnetic reversing valve is mounted on the valve body, the end cover is connected with the valve body through bolts, and the valve core is mounted inside a valve core hole in the valve body. The electrohydraulic reversing valve is characterized in that an annular flow guider is arranged on the valve body, and an elliptic flow hole is arranged on the valve core. Compared with the prior art, the electrohydraulic reversing valve provided by the utility model has the advantages of high flow and low power consumption.

Description

Electro-hydraulic reversing valve
Technical field
The utility model relates to a kind of valve, particularly relates to a kind of selector valve.
Background technique
Valve, particularly selector valve are a kind of oil circuit control units commonly used in the hydraulic system, and electro-hydraulic reversing valve is by pilot valve control bottom valve core movement, realize flow control, and this also is a kind of hydraulic control component commonly used in hydraulic control.But existing electro-hydraulic reversing valve exists: the one, and volume is big, and the electromagnet power consumption of control valve core movement is also big; The 2nd, because machining, the self-control conductance is a lineal shape on the valve body, and metering orifice is a circular hole on the spool, so the conductance sectional area is little, thus can only be a kind of high-power, the Small Flow Control element, this does not meet energy-conservation, requirement efficiently, must be improved.
The model utility content
The purpose of this utility model is the novel electro-hydraulic reversing valve that a kind of big flow, low power consumption will be provided.
The utility model is achieved in that electro-hydraulic reversing valve comprises solenoid directional control valve, valve body, end cap and spool, wherein solenoid directional control valve is contained in the valve body top, end cap is connected with valve body by screw, spool is contained in the spool bore on the valve body, on valve body, be provided with annular conductance, be provided with oval-shaped metering orifice on spool, all the other structures and component and existing product are same or similar.
Electro-hydraulic reversing valve of the present utility model is compared its main feature with existing product:
1, on valve body, the self-control conductance improvement of straight line shape is designed to the annular conductance of founding shaping,, increases flow to increase the sectional area of conductance;
2, on spool, make garden shape metering orifice into oval-shaped metering orifice, to increase flow.
Because above-mentioned improvement design back product of the present utility model and existing product specific discharge mutually obviously increase, and the solenoid valve power demand of promotion spool work reduces on the contrary, has saved electric energy.
Description of drawings
Fig. 1, existing product electro-hydraulic reversing valve structural representation;
Fig. 2, electro-hydraulic reversing valve structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is done further narration.
Electro-hydraulic reversing valve of the present utility model comprises as shown in Figure 2: solenoid directional control valve 1, valve body 2, end cap 3 and spool 4, wherein solenoid directional control valve 1 is contained in the top of valve body 2, end cap 3 is connected with valve body 2 by screw, spool 4 is contained in the spool bore on the valve body, on valve body 2, be provided with annular conductance 6, be provided with oval-shaped metering orifice 5 on spool 4, all the other structures and working principle and existing product are same or similar.
