Abstract
The utility model discloses a hydraulic control valve, comprising a valve body which is fixedly provided with a valve cover; a cavity is formed between one end of the valve cover and the valve body which is internally provided with a transverse constant-pressure valve cavity, an energy-storage valve cavity and a gear-shifting valve cavity, which are internally and respectively provided with a constant-pressure valve core, an energy-storage valve core and a gear-shifting valve core; a chute for leading the gear-shifting valve cavity and the cavity to be communicated is arranged between the gear-shifting valve cavity and the cavity; the valve cover is internally provided with a transverse through hole which is internally placed with a gear-shifting lever; the gear-shifting lever is fixedly provided with a gear-shifting deflector rod; the outer end of the gear-shifting deflector rod passes through the chute to be fixed on the gear-shifting valve core; the middle of the gear-shifting valve core is fixedly sheathed with a piston; the ring-shaped outer wall of the piston is provided with a ring-shaped groove; and the gear-shafting valve cavity is provided with a middle oil inlet, a left oil outlet and a right oil outlet. The hydraulic control valve has simple structure and convenient operation, and can change the flow direction of hydraulic oil by rotating the gear-shifting lever.
Description
Technical field:
The utility model relates generally to a kind of valve body, relates in particular to a kind of hydraulic control valve.
Background technique:
In hydraulic system, mainly form by parts such as valve body, spool, valve gap and springs as the hydrovalve of control unit.Analyze from principle, this control unit mainly is to satisfy the control requirement by the dependence matching gap between the two that the relative movement between valve body and the spool realizes to the control of oil liquid pressure, flow and direction.Therefore, the under high pressure necessary relative movement neatly of valve body and spool, and want to reduce internal leakage.
The model utility content:
The utility model purpose is exactly in order to remedy the defective of prior art, and a kind of hydraulic control valve of simple in structure, easy-to-operat is provided.
The utility model is achieved through the following technical solutions:
A kind of hydraulic control valve, include valve body, be installed with valve gap on the described valve body, be formed with cavity between described valve gap one end and valve body, be provided with horizontal level pressure valve pocket in the described valve body, energy storage valve pocket and gearshift valve pocket, described level pressure valve pocket, be separately installed with level pressure spool and energy storage spool and gearshift spool in energy storage valve pocket and the gearshift valve pocket, be provided with oil inlet passage in the described valve body, described oil inlet passage respectively with the level pressure valve pocket, the filler opening of energy storage valve pocket and gearshift valve pocket is connected, it is characterized in that: the chute that makes its mutual conduction is set between described gearshift valve pocket and described cavity, horizontal through hole is arranged in the described valve gap, be placed with gear level in the described through hole, be fixed with the gearshift driving lever on the described gear level, described gearshift driving lever outer end is passed on the fixing described gearshift spool of chute; Described gearshift spool center fixed is with piston, has annular groove on the annular outer wall of described piston; Filler opening and left and right oil outlet in the middle of described gearshift valve pocket is provided with, the and arranged on left and right sides of filler opening in the middle of described left and right oil outlet lays respectively at.
During the utility model work, drive the gearshift driving lever around the left and right swing of gear level, and then drive gearshift spool left and right moving in the gearshift valve pocket by the Rotation With Changing pin.
Filler opening position in the middle of the piston on the gearshift spool is positioned at, promptly the annular groove on the piston is corresponding with the position of middle filler opening, then the novel neutral gear position that is in of this use; When the piston on the gearshift spool was positioned at centre filler opening leftward position, hydraulic oil entered from middle filler opening, flowed out from right oil outlet; When the piston on the gearshift spool was positioned at centre filler opening right positions, hydraulic oil entered from middle filler opening, flowed out from left oil outlet.So, change the flow direction of hydraulic oil, and then play the effect of control hydraulic oil direction by the Rotation With Changing pin.
The utility model is regulated the pressure of hydraulic oil by the regulating action of level pressure spool, and then guarantees the stable of whole hydraulic system pressure.
The utility model has the advantages that:
Of the present utility model simple in structure, easy to operate, can change the flow direction of hydraulic oil by the Rotation With Changing pin.

Fig. 1 is a plan view of the present utility model.
Fig. 2 be A to sectional view.
Embodiment:
A kind of hydraulic control valve, include valve body 1, be installed with valve gap 2 on the described valve body 1, described valve gap 2 one ends and 1 of valve body are formed with cavity, be provided with horizontal level pressure valve pocket in the described valve body 1, energy storage valve pocket and gearshift valve pocket, described level pressure valve pocket, be separately installed with level pressure spool 3 and energy storage spool 4 and gearshift spool 5 in energy storage valve pocket and the gearshift valve pocket, be provided with oil inlet passage in the described valve body 1, described oil inlet passage respectively with the level pressure valve pocket, the filler opening of energy storage valve pocket and gearshift valve pocket is connected, the chute that makes its mutual conduction is set between gearshift valve pocket and described cavity, in the described valve gap 1 horizontal through hole is arranged, be placed with gear level 6 in the described through hole, be fixed with gearshift driving lever 7 on the described gear level 6, described gearshift driving lever 7 outer ends are passed on the fixing described gearshift spool 5 of chute; Described gearshift spool 5 center fixed are with piston 8, have annular groove 9 on the annular outer wall of described piston 8; Filler opening 10 and left and right oil outlet 11,12 in the middle of described gearshift valve pocket is provided with, the and arranged on left and right sides of filler opening 10 in the middle of described left and right oil outlet 11,12 lays respectively at.
