Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technical personnel in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figures 1 to 5 The utility model provides a technical solution: an upper liquid pipeline flow control valve is arranged on a connecting pipe 1, a valve 16 is arranged on the connecting pipe 1, an adjusting rod 4 is fixedly connected to the input end of the valve 16, the valve 16 is a ball valve, a flow meter is arranged in the inner cavity of the connecting pipe 1, the outer wall of the connecting pipe 1 is fixedly connected to a casing 3 through a bracket 2, an adjusting component is arranged in the inner cavity of the casing 3, a controller 5 is arranged on the outer wall of the casing 3, the controller 5 is electrically connected to the flow meter, and through the setting of the flow meter, the liquid flow flowing through the inner cavity of the connecting pipe 1 can be accurately monitored, and the flow data obtained by monitoring can be transmitted to the controller 5, The controller 5 compares and analyzes the monitored data with the set data. When the flow needs to be adjusted, the controller 5 controls the adjustment component to drive the adjustment rod 4 to rotate, thereby realizing the regulation of the opening size of the valve 16, which solves the problem that the valve 16 in the prior art can only control the size of the upper liquid flow but cannot accurately control the specific value of the upper liquid flow. After each adjustment of the opening of the valve 16, it is necessary to determine whether the opening of the valve 16 is appropriate by detecting the weight of the area. The valve 16 is a ball valve, which is a prior art and will not be elaborated on here. The controller 5 is a PLC controller 5, which is a prior art and will not be elaborated on here.

[0021] In this embodiment, the adjustment component includes a driving component, a limiting component, a slide plate 15, a rack 7 and a gear 6. The driving component is arranged on the rear side of the inner cavity of the casing 3, and the two limiting components are respectively arranged on the left and right sides of the inner cavity of the casing 3. The slide plate 15 is arranged between the two limiting components and connected to the driving component. The rack 7 is arranged at the front end of the slide plate 15, and the gear 6 is fixedly sleeved on the outer wall of the adjusting rod 4. Through the setting of the driving component, the slide plate 15 can slide up and down in the vertical direction under the limiting action of the limiting component, and then the rack 7 can slide up and down in the vertical direction. Since the rack 7 is meshed with the gear 6, when the rack 7 slides, the gear 6 can drive the adjusting rod 4 to rotate, thereby realizing the regulation of the opening size of the valve 16, which solves the problem that the valve 16 in the prior art can only control the size of the upper liquid flow rate, but cannot accurately control the specific value of the upper liquid flow rate. After each adjustment of the opening of the valve 16, it is necessary to determine whether the opening of the valve 16 is appropriate by detecting the weight of the detection area.

[0022] In this embodiment, the rack 7 is meshed with the gear 6, so that when the rack 7 slides, the gear 6 drives the adjusting rod 4 to rotate.

[0023] In this embodiment, the limiting assembly includes a limiting groove 13 and a limiting block 14. The limiting groove 13 is opened on one side of the inner wall of the casing 3. The limiting block 14 can be slidably embedded in the inner cavity of the limiting groove 13 and fixedly connected to the slide plate 15. Under the interaction between the limiting groove 13 and the limiting block 14, the slide plate 15 can always slide up and down in the vertical direction, and the rack 7 can always keep in meshing with the gear 6.

[0024] In this embodiment, the inner cavity of the limit groove 13 is matched with the outer wall of the limit block 14 and both are in a "T" shape, so that one end of the limit block 14 can always remain embedded in the inner cavity of the limit groove 13, thereby improving the stability of the limit assembly during use and preventing the limit block 14 from detaching from the inner cavity of the limit groove 13, resulting in the rack 7 and gear 6 on the slide plate 15 being separated.

[0025] In this embodiment, the driving assembly includes a motor 8, a rotating column 9, a roller 10, a slide 11 and a slider 12. The motor 8 is arranged at the top of the casing 3, and the output end of the motor 8 extends to the inner cavity of the casing 3. One end of the rotating column 9 is rotatably connected to the bottom end of the inner cavity of the casing 3 through a bearing, and the other end of the rotating column 9 is fixedly connected to the output end of the motor 8. The roller 10 is fixedly sleeved on the outer wall of the rotating column 9. The slider 12 is slidably embedded in the inner cavity of the slide 11 and is fixedly connected to the slide plate 15. The motor 8 is electrically connected to the controller 5. When the flow rate needs to be adjusted, the controller 5 controls the motor 8 to start, so that the motor 8 drives the roller 10 to rotate through the rotating column 9. Since the roller 1 0 is spiral and connected end to end, so when the slide groove 11 rotates, the slider 12 can drive the slide plate 15 to slide up and down in the vertical direction under the limiting action of the limit groove 13 and the limit block 14, so that the rack 7 can slide up and down in the vertical direction. Since the rack 7 is meshed with the gear 6, when the rack 7 slides, the gear 6 can drive the adjusting rod 4 to rotate, so as to realize the regulation of the opening size of the valve 16, which solves the problem that the valve 16 in the prior art can only control the size of the upper liquid flow but cannot accurately control the specific value of the upper liquid flow, and each time the opening of the valve 16 is adjusted, it is necessary to determine whether the opening of the valve 16 is appropriate by detecting the weight of the detection area.

[0026] In this embodiment, the slide groove 11 is spiral and connected end to end. When the slide groove 11 rotates, the slider 12 can drive the slide plate 15 to slide up and down in the vertical direction under the limiting action of the limiting groove 13 and the limiting block 14.

[0027] The use method and advantages of the utility model: When in use, the working process is as follows:

[0028] By setting the flow meter, the liquid flow through the inner cavity of the connecting pipe 1 can be accurately monitored, and the monitored flow data can be transmitted to the controller 5. The controller 5 compares and analyzes the monitored data with the set data. When the flow needs to be adjusted, the controller 5 controls the motor 8 to start, so that the motor 8 drives the roller 10 to rotate through the rotating column 9. Since the roller 10 is spiral and connected end to end, when the slide 11 rotates, the slider 12 can drive the slide plate 15 to slide up and down in the vertical direction under the limiting action of the limit groove 13 and the limit block 14, so that the rack 7 can slide up and down in the vertical direction. Since the rack 7 is meshed with the gear 6, when the rack 7 slides, the gear 6 can drive the adjusting rod 4 to rotate, so as to realize the regulation of the opening size of the valve 16, which solves the problem that the valve 16 in the prior art can only control the size of the upper liquid flow but cannot accurately control the specific value of the upper liquid flow, and each time the opening of the valve 16 is adjusted, it is necessary to determine whether the opening of the valve 16 is appropriate by detecting the weight of the area.
