[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-3 This utility model provides a hydraulic valve that facilitates control of valve opening, including a valve body 1. A water inlet valve pipe 2 is fixed to the left end of the valve body 1, and a water outlet valve pipe 3 is fixed to the right end of the valve body 1. Flanges 4 are fixed to the outer ends of both the water inlet valve pipe 2 and the water outlet valve pipe 3. Pressure sensors 5, flow rate sensors 6 and flow sensors 7 are provided on the surfaces of both the water inlet valve pipe 2 and the water outlet valve pipe 3. Support seats 8 are fixed to the upper and lower sides of the surface of the valve body 1. An upper opening and closing cylinder 9 is fixed to the upper support seat 8 by bolts, and a lower opening and closing cylinder 10 is fixed to the lower support seat 8 by bolts. An opening adjustment structure is provided inside the upper opening and closing cylinder 9 and the lower opening and closing cylinder 10.

[0025] The opening adjustment structure includes a cylinder cover 11, which is bolted to the ports of the upper opening cylinder 9 and the lower opening cylinder 10. The valve body 1 has a valve chamber 12 inside, and a ball groove 13 inside the valve chamber 12. A valve ball 14 rotates inside the ball groove 13. Two sets of valve shafts 15 are fixed on the valve ball 14. A rotating plate 16 is bolted to the valve shaft 15. A pivot pin 17 rotates on the rotating plate 16. The upper rotating plate 16 rotates to the upper electric rod 18 through the pivot pin 17, and the lower rotating plate 16 rotates to the lower electric rod 19 through the pivot pin 17. The outer ends of the upper electric rod 18 and the lower electric rod 19 are provided with hinge blocks 20. The inlet valve pipe 2 and the outlet valve pipe 3 are connected to the external pipeline through flanges 4, so that water can be transported so that the opening of the valve body 1 can be accurately controlled.

[0026] Furthermore, the inner end of the upper electric rod 18 is rotatably connected to the upper rotating plate 16 via the pivot pin 17, and the outer end of the upper electric rod 18 is rotatably connected to the upper opening and closing cylinder 9 via the hinge block 20, so that the extension of the upper electric rod 18 can drive the rotating plate 16 to rotate clockwise, thereby enabling the rotating plate 16 to drive the valve ball 14 to rotate clockwise via the valve shaft 15.

[0027] Furthermore, the inner end of the lower electric rod 19 is rotatably connected to the lower rotating plate 16 via the pivot pin 17, and the outer end of the lower electric rod 19 is rotatably connected to the lower opening and closing cylinder 10 via the hinge block 20, so that the extension of the lower electric rod 19 can drive the rotating plate 16 to rotate counterclockwise, thereby enabling the rotating plate 16 to drive the valve ball 14 to rotate counterclockwise via the valve shaft 15.

[0028] Furthermore, valve shafts 15 are fixed on the upper and lower sides of the surface of the valve ball 14, respectively. The valve shafts 15 pass through the valve body 1 and the receiving seat 8 and extend into the interior of the upper opening and closing cylinder 9 and the lower opening and closing cylinder 10, so that the upper electric rod 18 and the lower electric rod 19 can drive the valve ball 14 to rotate through the rotating plate 16.

[0029] Furthermore, the surface of the valve ball 14 is provided with a water passage hole with the same inner diameter as the inlet valve pipe 2 and the outlet valve pipe 3, so that the water flow can pass through the water passage hole on the surface of the valve ball 14, thereby the valve ball 14 can cut off the water flow.

[0030] Furthermore, there are two sets of upper electric levers 18 and lower electric levers 19, which are located on both sides of the upper and lower sets of rotating plates 16, respectively. This allows the upper electric lever 18 to drive the valve ball 14 to rotate clockwise to open via the rotating plate 16 and valve shaft 15, and the lower electric lever 19 to drive the valve ball 14 to rotate counterclockwise to close via the rotating plate 16 and valve shaft 15.

[0031] Furthermore, pressure sensor 5, flow velocity sensor 6, and flow rate sensor 7 are respectively installed on the surfaces of inlet valve pipe 2 and outlet valve pipe 3. The pressure, flow velocity, and flow rate of the water flow during water inlet can be monitored by the pressure sensor 5, flow velocity sensor 6, and flow rate sensor 7 on inlet valve pipe 2, and the pressure, flow velocity, and flow rate of the water flow during water outlet can be monitored by the pressure sensor 5, flow velocity sensor 6, and flow rate sensor 7 on outlet valve pipe 3.

[0032] Furthermore, controllers are installed inside the upper opening and closing cylinder 9 and the lower opening and closing cylinder 10. The controllers are electrically connected to the pressure sensor 5, the flow velocity sensor 6, the flow rate sensor 7, the upper electric rod 18, and the lower electric rod 19 respectively through wires, so that the controllers can control the pressure sensor 5, the flow velocity sensor 6, the flow rate sensor 7, the upper electric rod 18, and the lower electric rod 19 to work together individually or simultaneously.

[0033] In use, the inlet valve pipe 2 and the outlet valve pipe 3 are connected to external pipelines via flange 4, thus enabling water flow. As the water flows inside the inlet valve pipe 2, the pressure sensor 5 monitors the water pressure, the velocity sensor 6 monitors the water velocity, and the flow rate sensor 7 monitors the water flow rate. The monitored data is then transmitted to controllers located inside the upper and lower opening / closing cylinders 9 and 10 for data analysis, thereby obtaining... The controller transmits the analyzed data to the upper electric lever 18 and the lower electric lever 19 to the required opening degree of the valve body 1. At this time, the two sets of upper electric levers 18 extend and the two sets of lower electric levers 19 retract. Therefore, the upper electric lever 18 can drive the upper rotating plate 16 to rotate, which in turn drives the valve shaft 15 to drive the valve ball 14 to rotate inside the ball groove 13. This allows the water passage hole on the surface of the valve ball 14 to connect with the valve cavity 12, thus opening the valve body 1. The two sets of upper electric levers 18 can then precisely control the valve ball 14. The valve body 1 is rotated to open precisely. After the valve body 1 is opened, the water flows through the outlet valve pipe 3. The pressure sensor 5, flow velocity sensor 6, and flow rate sensor 7 on the outlet valve pipe 3 can monitor the pressure, flow velocity, and flow rate of the flowing water again. The monitored data is transmitted to the controllers located inside the upper and lower opening cylinders 9 and 10 for data analysis. The analyzed data is then transmitted to the upper electric lever 18 and the lower electric lever 19. Therefore, when it is necessary to gradually increase the opening degree of the valve body 1... When the valve body 1 is fully open, the upper electric lever 18 extends and drives the valve ball 14 to rotate clockwise through the upper rotating plate 16 and valve shaft 15. During this process, the lower electric lever 19 retracts. When it is necessary to gradually reduce the opening of the valve body 1 until the valve body 1 is fully closed, the lower electric lever 19 extends and drives the valve ball 14 to rotate counterclockwise through the lower rotating plate 16 and valve shaft 15. This enables the valve body 1 to be electrically opened or closed and drives the valve ball 14 to rotate precisely, thereby achieving precise electric opening or closing of the valve body 1.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
