Description

Technical Field

[0001] The utility model relates to an execution component for controlling a valve, in particular to an integrated electro-hydraulic execution mechanism. Background Art

[0002] After general valves are installed on pipelines, they are executed by manual control. Of course, they can also be controlled by motor transmission. When valves are used in high-pressure fluids in some large projects, the rotation of the valve discs in these large valves requires very large torque to drive, and at the same time, controlling the opening of the valve disc requires great precision. In this case, if the rotation of the valve disc in the valve is directly operated by the motor, it will cause the motor load to be too large, greatly affecting the service life of the motor. At the same time, the motor cannot be operated without electricity, which is disadvantageous for emergency situations. Utility Model Content

[0003] In order to solve the above problems, the purpose of the utility model is to provide an integrated electro-hydraulic actuator with multiple control operation modes and reliable structure, so as to ensure high torque output while ensuring safe and reliable operation.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an integrated electro-hydraulic actuator, comprising a base, on which an electronic control module, a hydraulic integrated module and a cylinder actuator module are installed, the cylinder actuator module comprises a cylinder and an actuator component, the piston rod of the cylinder drives the actuator component to move, the hydraulic integrated module is connected to the cylinder through an oil circuit and drives the piston rod of the cylinder to extend and retract, the electronic control module is conductively connected to the hydraulic integrated module, the hydraulic integrated module also comprises an energy storage device, the energy storage device is connected to the hydraulic integrated module, the actuator component comprises a rotatable output sleeve, a shift fork is welded on the outer wall of the output sleeve, the shift fork is drivingly connected to the end of the piston rod of the cylinder, so that the cylinder drives the output sleeve to transmit.

[0005] The hydraulic integrated module also includes a main oil tank, a gear pump, a main oil block and a manual oil block. The main oil block and the manual oil block are arranged on the oil circuit and are respectively provided with oil holes. A reversing valve and a manual pump are installed on the manual oil block. A cartridge valve is configured on the main oil block. The gear pump is driven by a motor, and the motor is controlled by an electronic control module. The output port of the gear pump is connected to an energy storage device, and the energy storage device includes an accumulator and an accumulator tank that are interconnected.

[0006] The end of the piston rod of the oil cylinder is connected with a vertical push rod, and the push rod is placed in the opening of the shift fork.

[0007] The beneficial effects of the utility model are as follows: the output sleeve can be connected to the valve stem on the valve in a transmission manner. Since it is driven by the oil cylinder, the output sleeve can have a large torque, so that a large valve can be driven. The electronic control module, the hydraulic integrated module and the oil cylinder execution module can be replaced individually in circles, making later maintenance more convenient. The electronic control module can accurately control the gear pump in the hydraulic integrated module to carry out the flow direction and flow speed of the oil, and can be operated manually on the spot, while the energy storage device can realize emergency control operation in the absence of electricity. In this way, a technical effect of multiple control operation modes and reliable structure is achieved, thereby ensuring a large torque output while ensuring the safety and reliability of the operation.

[0012] The present invention is specifically described below through embodiments, which are only used to further illustrate the present invention and should not be construed as limiting the protection scope of the present invention.

[0013] like Figure 1 — Figure 3 As shown, this embodiment discloses an integrated electro-hydraulic actuator, including a base 1, on which an electronic control module 2, a hydraulic integrated module 3 and a cylinder actuator module 4 are installed, the cylinder actuator module 4 includes a cylinder 41 and an actuator 42, the piston rod of the cylinder 41 drives the actuator 42 to move, the hydraulic integrated module 3 is connected to the cylinder 41 through an oil circuit and drives the piston rod of the cylinder 41 to extend and retract, the electronic control module 2 is conductively connected to the hydraulic integrated module 3, the hydraulic integrated module 3 also includes an energy storage device 5, the energy storage device 5 is connected to the hydraulic integrated module 3, the actuator includes a rotatable output sleeve 6, a shift fork 61 is welded on the outer wall of the output sleeve 6, the shift fork 61 is drivingly connected to the end of the piston rod of the cylinder 41, so that the cylinder 41 drives the output sleeve 6 to transmit, and the output sleeve 6 is installed on the valve and is drivingly connected to the valve stem.

[0014] The hydraulic integrated module 3 also includes a main oil tank 31, a gear pump 32, a main oil block 33 and a manual oil block 34. The main oil block 33 and the manual oil block 34 are arranged on the oil circuit and are respectively provided with oil holes. A reversing valve 35 and a manual pump 36 are installed on the manual oil block 34 to realize manual control. The main oil block 33 is provided with a cartridge valve 37. The cartridge valve 37 mainly realizes the opening or closing of the liquid circuit. When used in combination with other hydraulic control valves, the control of the direction, pressure and flow of the oil in the system oil circuit is realized. The gear pump 32 is driven by a motor 321, and the motor 321 is driven by an electronic control module 2 for control, the electronic control module 2 includes a control processor, a Bluetooth module, an infrared module, a display and other control components.

The energy storage device 5 converts the energy in the system into compression energy or potential energy and stores it at an appropriate time. When the system needs it, the compression energy or potential energy is converted into hydraulic or gas pressure energy and released to replenish the system.

[0015] The piston rod end of the oil cylinder 41 is connected with a vertical push rod 8, and the push rod 8 is placed in the opening of the shift fork 61. In this way, the oil cylinder 41 can drive the output sleeve 6 to drive the valve stem to perform forward and reverse rotation.

[0016] By adopting the above technical scheme, the output sleeve 6 can be connected to the valve stem on the valve. Since it is driven by the oil cylinder 41, the output sleeve 6 can have a large torque. The electronic control module 2, the hydraulic integrated module 3 and the oil cylinder execution module 4 can replace the circumference separately, making the later maintenance more convenient. The electronic control module 2 can accurately control the gear pump 32 in the hydraulic integrated module 3 to carry out the flow direction and flow speed of the oil, and can be operated manually on the spot, and the energy storage device can realize emergency control operation in the absence of electricity. In this way, a variety of control operation modes and reliable structural technical effects are achieved, thereby ensuring large torque output while ensuring the safety and reliability of operation.
