Description

Technical Field

[0001] The utility model relates to the technical field of rotary hydraulic valves, in particular to a rotary precision hydraulic valve spool. Background Technique

[0002] The rotary hydraulic valve is a commonly used hydraulic control device, mainly used to control the flow, pressure and direction in the hydraulic system. It changes the working state of the hydraulic system by rotating the spool. The structure of the rotary hydraulic valve generally includes a valve body, a spool and a rotating shaft. The valve body is the outer shell of the valve, used to fix the spool and the rotating shaft, and also plays a sealing role. The spool is the key component to control the flow, pressure and direction. It changes the working state in the hydraulic system by rotating. The rotating shaft is the component connecting the spool and the external operating mechanism, used to transmit the operating force.

[0003] Most of the existing rotary hydraulic valves change the liquid flow channel in the hydraulic system by rotating the spool. At different rotation positions, the spool can make the liquid flow in the hydraulic system enter different channels, so as to realize the control of the flow. Most of the outlets of the rotary hydraulic valves are arranged at the bottom, and the liquid is discharged by the action of gravity and centrifugal force when discharging the liquid flow. However, in actual use, due to the relatively fast rotation speed of the spool, the liquid flow inside the spool channel is not timely enough, which will reduce the conveying efficiency of the rotary hydraulic valve, and further reduce the use effect of the rotary hydraulic valve.

Side bins are respectively arranged at both ends of the surface of the valve body. Side plates are respectively fixedly connected to both ends of the surface of the valve body.

[0008] Furthermore, the liquid discharging mechanism includes connecting pieces. There are a plurality of connecting pieces, and the plurality of connecting pieces are respectively rotatably connected between every two feeding blades. A second rotating shaft is sleeved at the bottom of each of the plurality of connecting pieces. A plurality of connecting holes are provided on the surfaces of the two rotating sealing rings.

[0019] Refer to Figures 1 - 6 , the rotary precision hydraulic valve spool includes a valve body 1. The feed pipe 11 and the discharge pipe 12 are respectively fixedly connected to the upper and lower surfaces of the valve body 1. Flanges 13 are fixedly connected to both ends of the feed pipe 11 and the discharge pipe 12. A plurality of feeding blades 3 are rotatably connected inside the valve body 1. The plurality of feeding blades 3 are evenly distributed in a ring shape. A rotating mechanism for rotating the plurality of feeding blades 3 is provided on the surface of the valve body 1. Side chambers 14 are respectively arranged at both ends of the surface of the valve body 1. Side plates 16 are respectively fixedly connected to both ends of the surface of the valve body 1. The two side plates 16 are respectively arranged inside the two side chambers 14. A liquid discharge mechanism is arranged inside the valve body 1. Through the arrangement of a plurality of connecting pieces 4, during use, when the plurality of feeding blades 3 rotate to convey the liquid, when the water body is output, under the action of the two toothless rings 15, the plurality of connecting pieces 4 rotate, so that the liquid between the plurality of feeding blades 3 is discharged more quickly, thereby improving the use effect of the device.

[0020] Refer to Figures 1 - 4 , in a preferred embodiment, the rotating mechanism includes a first rotating shaft 31. Rotary seal rings 5 are sleeved on both opposite sides inside the valve body 1. The plurality of feeding blades 3 are fixedly connected to the surface of the first rotating shaft 31. Both ends of the first rotating shaft 31 are respectively sleeved inside the two rotary seal rings 5. Both ends of the two first rotating shafts 31 are respectively sleeved inside the two side plates 16. A motor 2 is installed on the surface of one of the side plates 16. The output end of the motor 2 is fixedly connected to one end of the first rotating shaft 31, which is used to drive the plurality of feeding blades 3 to rotate, so as to convey the liquid.

[0021] Refer to Figure 2 , Figure 4 , Figure 5 and Figure 6, in a preferred embodiment, the liquid discharging mechanism includes connecting pieces 4. There are multiple connecting pieces 4, and the multiple connecting pieces 4 are respectively rotatably connected between every two feeding blades 3. A second rotating shaft 41 is sleeved at the bottom of each of the multiple connecting pieces 4. A plurality of connecting holes 51 are provided on the surfaces of the two rotary sealing rings 5. The two ends of each of the multiple second rotating shafts 41 are respectively sleeved inside the multiple connecting holes 51 on the surfaces of the two rotary sealing rings 5. Torsion springs 42 are respectively sleeved at the two ends of each of the multiple second rotating shafts 41. One ends of the multiple torsion springs 42 are respectively fixedly connected to the two ends of the bottom of the connecting piece 4, and the other ends of the multiple torsion springs 42 are respectively fixedly connected to the opposite sides of the two rotary sealing rings 5. A plurality of gears 43 are respectively rotatably connected inside the two side bins 14.

[0022] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects: Through the arrangement of the multiple connecting pieces 4, when in use, when the multiple feeding blades 3 rotate to convey the liquid, while the water body is being output, under the action of the two toothless rings 15, the multiple connecting pieces 4 rotate, so that the liquid between the multiple feeding blades 3 is discharged more quickly, thereby improving the use effect of the device. When in use, the flanges 13 on the feed pipe 11 and the discharge pipe 12 need to be connected respectively. When in use, the driving motor 2 drives the first rotating shaft 31 and the multiple feeding blades 3 to rotate, so that the liquid entering through the feed pipe 11 can be conveyed through between the multiple feeding blades 3. When the conveyed liquid reaches the bottom, it can be output through the discharge pipe 12 under the action of gravity. During this process, when the multiple gears 43 pass through the toothless ring 15 at the bottom, they will drive the second rotating shaft 41 and the connecting piece 4 to rotate, so that the connecting piece 4 rotates from one side of one feeding blade 3 to the other side of another feeding blade 3, so as to squeeze the liquid between the two feeding blades 3, so that the conveyed liquid is discharged more thoroughly and quickly. When the gear 43 is no longer in contact with the toothless ring 15, under the action of the torsion spring 42, the multiple connecting pieces 4 will return to their positions, thereby improving the use effect of the device.
