[0019] Please see Figure 1-4 As shown, this utility model relates to an integrated hydraulic valve opening and closing device, applicable to the fields of water conservancy, water supply and drainage, and water purification. It includes a control system 1, a hydraulic pump station 2, a first hydraulic pipeline 3, a second hydraulic pipeline 4, a valve opener 5, a transmission rod 6, a valve assembly 7, and a valve well 8. The control system 1 and the hydraulic pump station 2 are located outside the valve well 8, and the control system 1 is electrically connected to the hydraulic pump station 2. The valve opener 5, the transmission rod 6, and the valve assembly 7 are located inside the valve well 8. The hydraulic pump station 2 is connected to the valve opener 5 via the first hydraulic pipeline 3 and the second hydraulic pipeline 4. The transmission rod 6 is rotatably mounted on the valve opener 5. The valve assembly 7 is mounted on a water pipe 81 in the valve well 8, and the transmission rod 6 is connected to the valve assembly 7. Rotation of the transmission rod 6 controls the valve assembly 7 to open or close the water pipe 81.

[0020] In this embodiment, the control system 1 and the hydraulic pump station 2 are located outside the valve well 8, while the valve opener 5, the transmission rod 6, and the valve assembly 7 are located inside the valve well 8. This utility model places the power supply equipment outside the valve well 8, and there is no power supply inside the valve well 8, thus ensuring the safe operation and stable operation of the equipment.

[0021] Furthermore, the valve assembly 7 includes a valve body 71 and a valve core 72. The valve body 71 has a cavity 711 inside for the valve core 72 to open or close. The valve core 72 is rotatably disposed in the cavity 711. The transmission rod 6 is connected to the valve core 72. The rotation of the transmission rod 6 drives the valve core 72 to rotate, thereby controlling the valve assembly 7 to open or close. The valve body 71 has an inlet 712 and a drain 713 on both sides connected to the water pipe 81. The inlet 712 and the drain 713 are respectively connected to the cavity 711.

[0022] In this embodiment, the output pressure of the hydraulic pump station 2 is converted according to the required torque, and the hydraulic torque driving the load rotation is 300N. Further, the hydraulic pump station 2 includes a hydraulic pump 21 and a cylinder 22. The hydraulic pump 21 is a gear pump or vane pump, and the oil tank size is 550*400. The hydraulic pump 21 is mounted on the cylinder 22, and the hydraulic pump 21 is connected to a valve opener 5 through a first hydraulic pipe 3 and a second hydraulic pipe 4. The hydraulic pump 21 draws hydraulic oil from the cylinder 22, and the hydraulic oil forms pressure within the hydraulic pump 21 and is discharged to the first hydraulic pipe 3 or the second hydraulic pipe 4. In this embodiment, the hydraulic oil is an environmentally friendly anti-wear hydraulic oil.

[0023] In this embodiment, the valve opener 5 is provided with a forward rotation interface 51 and a reverse rotation interface 52. The forward rotation interface 51 is connected to the first hydraulic pipeline 3, and the reverse rotation interface 52 is connected to the second hydraulic pipeline 4. A drive shaft 53 is provided inside the valve opener 5. When hydraulic oil flows into the valve opener 5 from the first hydraulic pipeline 3 or the second hydraulic pipeline 4, the hydraulic oil pushes the drive shaft 53 inside the valve opener 5, causing the drive shaft 53 to rotate forward or reverse. The drive shaft 53 is exposed at the bottom of the valve opener 5, and the drive rod 6 is mounted on the drive shaft 53.

[0024] In this embodiment, the hydraulic pump 21 is controlled by the control system 1 to draw hydraulic oil from the cylinder 22, creating pressure and discharging the hydraulic oil to the first hydraulic pipe 3 or the second hydraulic pipe 4. The hydraulic oil ultimately flows to the valve opener 5 through the first hydraulic pipe 3 or the second hydraulic pipe 4. In this embodiment, when hydraulic oil enters the valve opener 5 from the first hydraulic pipe 3, the valve opener 5 drives the transmission rod 6 to rotate forward, thereby driving the valve core 72 to rotate and opening the valve body 71. When hydraulic oil enters the valve opener 5 from the second hydraulic pipe 4, the valve opener 5 drives the transmission rod 6 to rotate in reverse, thereby driving the valve core 72 to rotate and closing the valve body 71.

[0025] Furthermore, the integrated hydraulic valve opening and closing device is also equipped with an integrated leakage detection device (not shown in the figure) electrically connected to the control system 1. When a leakage problem occurs, the leakage will be detected in time and an alarm will be triggered to ensure the safety of the device.

[0026] This invention allows for both local and remote manual control of the valve's opening and closing via control system 1. The valve can be manually controlled by sending a command code to control system 1, which then opens or closes the valve upon receiving the signal. This remote control allows for flow restriction or flow regulation of water pipe 81. Alternatively, a flow meter (not shown) and a level sensor (not shown) can be installed. These sensors monitor the flow rate and water level in real time and upload this data to control system 1. Control system 1 then automatically opens and closes the valve based on the data, automatically restricting or regulating the flow in water pipe 81 without manual intervention. Alternatively, the flow can be manually restricted or regulated by opening the manhole cover.

[0027] In this invention, the control system 1 can realize platform data interconnection, thereby enabling the simultaneous activation of valve openers 5 on multiple sets of hydraulic pump stations 2 to open, close, limit flow, and regulate valve components 7, thereby improving work efficiency and saving personnel costs.

[0028] This utility model relates to an integrated hydraulic valve opening and closing device. This device can limit the flow or regulate the flow rate within the water pipe 81 through local manual, remote, or automatic system control, eliminating the need for personnel to enter the valve well 8 for manual opening and closing operations, thus ensuring worker safety and improving work efficiency. Furthermore, this utility model, through its control system, can simultaneously open, close, and regulate the flow of multiple integrated hydraulic valves, enabling timely water flow adjustment and improving efficiency.

[0029] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
