Description

Technical Field

[0001] This utility model relates to the field of multi-way valves, and in particular to a multi-way valve with an electro-hydraulic lock structure. Background Technology

[0002] Currently, mechanical hydraulic lock structures are commonly used in the hydraulic transmission systems of tractors on the market. However, mechanical hydraulic lock structures have problems such as complex operation and poor practicality.

[0003] Therefore, it is necessary to develop a controllable hydraulic lock structure to overcome the above problems. Utility Model Content

[0004] Purpose of the utility model: In view of the shortcomings and defects of the existing technology, this utility model provides an electrically controlled hydraulic lock structure, which adds a solenoid valve. The opening and closing of the oil circuit is controlled by the on and off of the solenoid valve, thereby improving the functionality and practicality of the multi-way valve.

[0005] Technical solution: The present invention relates to an electro-hydraulic lock structure, characterized in that it includes an inlet valve body, several main valve bodies, an electro-hydraulic lock valve block, a solenoid valve, and a return valve body; the solenoid valve locks the working cylinders in the same position; the electro-hydraulic lock valve block is mounted on the main valve body.

[0006] The electro-hydraulic lock valve block is fixed to the main valve body.

[0007] The electro-hydraulic lock valve block is fixed to the main valve body by screws.

[0008] The number of screws is 4.

[0009] Several of the main valve bodies are connected in sequence.

[0010] Beneficial Effects: Compared with existing technologies, this utility model has the following significant advantages: The electro-controlled hydraulic lock structure multi-way valve of this utility model completely replaces the previous mechanical hydraulic lock structure, and it is controlled by electricity, making operation simple and more practical. In actual use, it allows the actuator to remain in any position while working. The electro-controlled hydraulic lock structure multi-way valve of this invention is used in the locking circuit of a hydraulic system. When a stop is required, the system requires the controlled object to remain stationary. When the hydraulic actuator needs to move, the opening and closing of the solenoid valve is controlled electrically to return the oil to the tank. The electro-controlled hydraulic lock structure multi-way valve can control the locking of the oil circuit, allowing the oil circuit to be opened and closed at any time. Attached Figure Description

[0014] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0015] This utility model discloses an electro-hydraulic lock structure, comprising an inlet valve body 1, several main valve bodies 2, an electro-hydraulic lock valve block 3, a solenoid valve 4, and a return valve body 5. The solenoid valve 4 locks the working cylinders in the same position. The electro-hydraulic lock valve block 3 is mounted on the main valve body 2. The electro-hydraulic lock valve block 3 is fixed to the main valve body 2 by four screws. The several main valve bodies 2 are connected sequentially.

[0016] The working cylinder is locked in the same position by solenoid valve 4. When it descends, solenoid valve 4 is energized to allow the oil in the cylinder to return to the oil tank, causing the cylinder to descend.

[0017] As shown in the figure, when the main valve core moves, pressurized oil is drawn out from port P, passes through the valve core, and enters the solenoid valve, activating the solenoid valve. When the actuator needs to stop working, the valve core returns to the neutral position, the solenoid valve locks the circuit, and the actuator stops working. When movement is required, the main valve core moves, the solenoid valve is energized, and the hydraulic oil returns to the oil tank.

[0018] This utility model discloses an electro-hydraulic lock structure, including a hydraulic lock function. It comprises an inlet valve body and multiple main valve bodies connected in sequence. The electro-hydraulic lock structure also includes a multi-way valve, which adds an electro-hydraulic valve block and a solenoid valve to a conventional multi-way valve to achieve the function of an electro-hydraulic lock structure multi-way valve. The hydraulic lock function of this utility model is typically used in the locking circuit of a hydraulic system. When a stop is required, the system requires that the controlled object cannot move. When the hydraulic actuator needs to move, the solenoid valve is energized to open, allowing the oil to return to the tank.
