The hydraulic reversing valve is simple in structure, manual operation and remote operation are randomly switched, the proportional flow is controlled manually and remotely, the proportional effect is good, the price is low, the maintenance technology difficulty is low, and the hydraulic reversing valve is suitable for being popularized.
The utility model adopts the technical proposal that: a manual and remote control proportional flow hydraulic reversing valve comprises a valve body, an electric handle and an electromagnetic clutch. The valve is characterized in that the valve body is provided with a valve core hole, the valve core is arranged in the valve core hole, one end of the valve core is sleeved with a spring, and the other end of the valve core is connected with an electric handle. The electric handle can drive the valve core to axially move in the valve core hole; a clutch device is fixedly arranged between the electric handle and the valve body, an electromagnetic clutch of the clutch device is fixedly connected with a rack, and the rack is matched with the gear. One end of the clutch device is fixedly connected with the electric handle, and the other end of the clutch device is fixedly connected with the valve bracket. When the electromagnetic clutch of the clutch device is electrified, magnetic force is obtained, so that the gear and the rack are meshed; when the electromagnetic clutch loses magnetic force due to non-electrification, the corresponding gear and the rack are separated due to the fact that the electromagnetic clutch loses magnetic force. The electric handle is formed by connecting a motor, a motor shaft, a gear and a connecting rod, wherein the gear is fixedly sleeved on the motor shaft. The electric handle is fixed on the electric handle support, the electric handle support is connected with the valve support, and the valve support is fixed on the valve body.
The hydraulic valve realizes the control and reversing of the flow by the movement distance of the valve core in the valve core hole. When the electromagnetic clutch of the clutch device is not electrified, the magnetic force is lost, the gear and the rack are separated because the electromagnetic clutch loses the magnetic force, and at the moment, the electric handle can be moved by hand, so that the valve core moves back and forth, and the manual control function is realized. When the electromagnetic clutch of the clutch device is electrified, magnetic force is obtained, the gear is meshed with the rack, the electric handle is driven by the forward rotation and the reverse rotation of the motor to enable the valve core to move back and forth, the flow control and the reversing are achieved, and the remote control is realized.
The beneficial effects of the utility model are that add clutch between the handle of manual proportion flow hydraulic reversing valve and the valve body, through the power supply of clutch get lost be electromagnetic force have or not, drive the separation or the meshing of gear and rack, realize manual and remote control's purpose, realize switching manual and remote control at will. Has simple and novel structure, reliable performance and is suitable for general popularization.

Detailed Description
The present embodiment is further described with reference to the accompanying drawings:
as can be seen from fig. 1-4, the manual and remote control proportional flow hydraulic directional valve comprises a valve body 9, an electric handle 12 and an electromagnetic clutch 4. The valve body 9 is provided with a valve core hole, the valve core 7 is arranged in the valve core hole, one end of the valve core 7 is sleeved with the spring 8, and the other end is connected with the electric handle 12. The electric handle 12 is fixed on the electric handle bracket 5, the electric handle bracket 5 is connected with the valve bracket 6, and the valve bracket 6 is fixed on the valve body 9. The electric handle 12 can drive the valve core 7 to axially move in the valve core hole.
As shown in fig. 1, the power transmission and clutch control between the electric handle 12 and the valve body 9 is constituted by connecting the gear 2, the rack 3, the electromagnetic clutch 4, and the valve holder 6, and the power is transmitted from the gear 2 to the rack 3 and the electromagnetic clutch 4. Wherein, a clutch device is composed of a gear 2, a rack 3 and an electromagnetic clutch 4. An electromagnetic clutch 4 of the clutch device is connected with a rack 3, the rack 3 is matched with a gear 2, one end of the clutch device is fixedly connected with an electric handle 12, and the other end of the clutch device is fixedly connected with a valve bracket 6. Meanwhile, the electric handle bracket 5 is connected with the valve bracket 6 which is fixed on the valve body 9.
When the electromagnetic clutch 4 of the clutch device is electrified, magnetic force is obtained, so that the gear 2 is meshed with the rack 3; when the electromagnetic clutch 4 loses magnetic force due to non-electrification, the corresponding gear 2 and the rack 3 are separated due to the loss of magnetic force of the electromagnetic clutch 4.
As shown in FIG. 5, the electric handle 12 is formed by connecting a motor 1, a motor shaft 10, a gear 2 and a connecting rod 11, wherein the gear 2 is fixedly sleeved on the motor shaft 10. The electric handle 12 is fixed on the electric handle support 5.
As can be seen from fig. 6-7, the working principle of the right movement of the electric handle during the electric operation is that when the electromagnetic clutch 4 of the clutch device is energized, magnetic force is obtained to engage the gear 2 and the rack 3, and at this time, the electric handle 12 is driven by the positive and negative rotation of the motor 1 to move the valve core 7 back and forth, so as to achieve the purposes of flow control and commutation, and at this time, the electric handle is remotely controlled; when the electromagnetic clutch 4 of the clutch device loses magnetic force due to non-electrification, the corresponding gear 2 and the rack 3 are separated due to the loss of magnetic force of the electromagnetic clutch 4, and at the moment, the electric handle 12 can be moved by hand to enable the valve core 7 to move back and forth, so that the manual control function is realized.
The purpose of manual and remote control is realized by the fact that the gear 2 is separated from or meshed with the rack 3 through the loss or gain of power supply of the clutch device, namely the existence of electromagnetic force. Namely, an electromagnetic clutch of the clutch device is meshed with a gear and can drive an electric handle to drive a valve core to move axially by a motor; if the electromagnetic clutch loses the separation of the gear and the rack, the electric handle can be moved by hand to drive the valve core to move axially.
The utility model has the advantages that add clutch between the handle of manual proportional flow hydraulic reversing valve and valve body, solved the technological problem who possesses manual and remote control function simultaneously. Because of simple structure is novel, the dependable performance is fit for generally promoting.
