Detailed Description

The technical scheme of the utility model is further described by combining the detailed description and the attached drawings of the specification.

As shown in fig. 1 to 4, the hydraulic double-acting hydraulic control valve comprises a double-acting actuator 1, a hydraulic lock 2, an overflow valve 3, a motor 4, a bidirectional hydraulic pump 5 and a wire through hole 6, wherein the hydraulic lock 2 and the overflow valve 3 form a functional valve block. An A, B oil port is arranged on the power unit, the A oil port is communicated with the cavity of the double-acting actuator 1, and the B oil port is communicated with the rack cavity of the double-acting actuator 1; A. hydraulic lock 2 is connected with to B hydraulic fluid port below, and hydraulic lock 2 is connected to two oil-outs of two-way hydraulic pump 5. The output ends of the two sides of the bidirectional hydraulic pump 5 are provided with overflow valves 3, so that the overload protection effect is achieved. The shaft of the bidirectional hydraulic pump 5 is connected with the shaft of the motor 4 through a coupler, and the coupler plays a role in transmitting mechanical energy. The motor 4 can work in two directions, the motor 4 drives the two-way hydraulic pump 5 to rotate, and the two-way hydraulic pump 5 pumps hydraulic oil from an oil tank. In the embodiment, the oil tank is positioned through the spigot of the valve block and is fastened on the functional valve block through the screw. The hydraulic lock 2 comprises a hydraulic control reversing valve core 21 and a one-way valve 22; the number of the check valves 22 is two, and the pilot operated directional spool 21 is disposed between the two check valves, as shown in fig. 6. An oil suction port of the bidirectional hydraulic pump 5 adopts a heavy hammer type oil inlet joint 7; the heavy hammer type oil inlet joint 7 is connected with a bidirectional hydraulic pump 5 through a rubber pipe 8, and a spring is sleeved outside the rubber pipe 8. The power unit has a casing with a wire hole 6, and the wire of the motor 4 is led out from the wire hole 6 and can be connected to a control box of a user, as shown in fig. 4.

The working process of the utility model is as follows: as shown in fig. 5 and 6, when the motor 4 rotates left, the bidirectional hydraulic pump 5 is driven to rotate right, the oil pushes the hydraulic control directional control valve core 21 to move left to push the steel ball of the one-way valve on the left side to open the oil path on the oil port side a, the oil port B inputs the oil into the rack cavity of the double-acting actuator 1, the volume of the rack cavity is pushed to expand by hydraulic energy, the volume of the cavity of the oil port a is pushed to reduce, the central gear is driven to rotate, and therefore the valve is rotated to be closed or opened;
