Detailed implementation mode

[0022] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention; obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0023] Embodiment:

[0024] Please refer to Figures 1 - 5As shown, the flow balancing device of the desalted water treatment system includes a main pipeline 1 and a connecting sleeve 8. A transverse pipe 2 is arranged at one end of the main pipeline 1. Sealing end caps 201 are screwed on both ends of the transverse pipe 2 to facilitate effective cleaning of the inside of the transverse pipe 2. In the desalted water treatment system, water flow can be diverted through the main pipeline 1 to achieve separate treatment and improve treatment efficiency. A diverter pipe A31 and a diverter pipe B32 are respectively arranged on one side of the transverse pipe 2. The diverter pipe A31 and the diverter pipe B32 are parallel to each other. The diverter pipe A31 is parallel to the diverter pipe B32. A flow meter 4 is provided at one end of the shunt pipe B32 near the cross pipe 2 to monitor the internal flow of the shunt pipe A31 and the shunt pipe B32 in real time. A rotating shaft A5 is rotatably installed on one side of the shunt pipe B32. A ball valve A61 for controlling the internal flow of the shunt pipe B32 is provided at one end of the rotating shaft A5. The angle of the ball valve A61 is controlled by the rotating shaft A5 to control the flow of the shunt pipe B32. A rotating disk 7 is provided at one end of the rotating shaft A5 away from the ball valve A61. The shunt pipe A31 near the shunt pipe A rotating shaft B10 is rotatably mounted on one side of B32, and a ball valve B62 for controlling the flow inside the shunt pipe A31 is arranged at one end of the rotating shaft B10. The angle of the ball valve B62 is controlled by the rotating shaft B10, thereby controlling the flow of the shunt pipe A31. A connecting sleeve 8 is rotatably mounted on the side of the turntable 7 away from the rotating shaft A5, and a gear 801 is arranged at one end of the connecting sleeve 8. An installation groove 702 is opened inside the turntable 7, and the gear 801 is placed inside the installation groove 702. A connecting sleeve 8 is rotatably mounted on the side of the turntable 7 away from the rotating shaft A5, and a gear 801 is arranged at one end of the connecting sleeve 8. A mounting groove 702 is opened inside the turntable 7, and the gear 801 is placed inside the mounting groove 702. A connecting sleeve 8 is rotatably mounted on the side of the turntable 7 away from the rotating shaft A5, and a gear 801 is arranged at one end of the turntable 7 away from the rotating shaft B10. The square rod 11, the end of the square rod 11 slides inside the connecting sleeve 8, and a locking bolt 803 is screwed on the upper surface of the connecting sleeve 8. The square rod 11 is fixed to the connecting sleeve 8 by the locking bolt 803 to adapt to the distance between different pipelines, and the ball valve B62 rotates together with the gear 801, and then the ball valve B62 can be controlled by controlling the gear 801. When the gear 801 and the turntable 7 remain fixed, the ball valve A61 and the ball valve B62 rotate together, otherwise they can be controlled separately to adjust the flow difference between the two pipelines.

[0025] Among them, rotating shafts can be set at both ends of ball valve A61 and ball valve B62 to realize the connection control of multiple pipelines, not limited to two pipelines. The flow difference refers to the blockage of scale or foreign matter inside the pipeline, which causes the flow of the two pipelines to be inconsistent even if the valve is fully opened. At this time, the flow inside the two pipelines can be made consistent by reducing the valve inside the large-flow pipeline alone, and synchronous opening or closing can be achieved.

[0026] Please refer to Figure 3 As shown, an outer hand wheel 701 is provided on the outer side of the turntable 7 to facilitate the operation of the turntable 7 .

[0027] Please refer to Figure 3 and Figure 4As shown, the inner wall of the installation groove 702 is symmetrically provided with sliding holes 703, and a limit slider 704 is slidably installed inside the sliding hole 703. The limit slider 704 and the gear 801 are meshed with each other. The meshing of the two ensures the fixation of the gear 801 and the turntable 7, thereby realizing the synchronous rotation of the two valve bodies.

[0028] Among them, a connecting rod 705 is provided at one end of the limit slider 704 that faces away from each other. The connecting rod 705 passes through the turntable 7. A pulling plate 706 is provided at the end of the connecting rod 705. The pulling plate 706 is placed on the outside of the turntable 7 to facilitate the external pulling operation of the limit slider 704. A spring 707 is sleeved on the surface of the connecting rod 705. The spring 707 is placed inside the sliding hole 703. One end of the spring 707 is in contact with the limit slider 704. The spring 707 can ensure that the limit slider 704 always maintains cooperation with the gear 801 when no force is applied.

[0029] Please refer to Figure 2 As shown, a cover plate 9 for sealing the mounting groove 702 is installed on the surface of the turntable 7 on one side away from the rotating shaft A5 by bolts, and a connecting sleeve 8 passes through the cover plate 9. The outer surface of the cover plate 9 is evenly engraved with scale lines 901 with the axis of the connecting sleeve 8 as the center. A pointer 802 is provided on the surface of the connecting sleeve 8. The pointer 802 is placed on the outer side of the cover plate 9. The pointer 802 corresponds to the scale line 901 to facilitate the judgment of the angle of the valve body.

[0030] Working principle: water flows through the main pipe 1, and then flows into the diversion pipe A31 and the diversion pipe B32 through the cross pipe 2, and the flow of the diversion pipe A31 and the diversion pipe B32 is observed by two flow meters 4 respectively, and the flow of the diversion pipe B32 and the diversion pipe A31 is controlled by rotating the ball valve A61 or the ball valve B62. Due to the existence of the springs 707 on both sides, the two limit sliders 704 have a force to approach each other, and then cooperate with the gear 801 to ensure the stability of the angle of the connecting sleeve 8. At this time, rotating the outer hand wheel 701 can simultaneously control the rotation of the ball valve A61 and the ball valve B62 to achieve the flow of the two pipes. The amount of synchronous control is achieved. When a flow difference occurs, the pull plate 706 can be pulled outward to disengage the limit slider 704 from the gear 801. At this time, the connecting sleeve 8 and the turntable 7 can rotate independently. Due to the existence of the square rod 11, the connecting sleeve 8 and the ball valve B62 rotate synchronously. Then, the relative angle of the ball valve A61 and the ball valve B62 can be determined by matching the pointer 802 and the scale line 901. Then, the angle difference between the two can be used to compensate for the flow difference between the diversion pipe B32 and the diversion pipe A31, so as to achieve a balance in the flow between the two pipes, and then ensure that the flow in each pipe is consistent during the reverse osmosis process.

[0031] The above are only the preferred specific embodiments of the present utility model; however, the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its improved concept, making equivalent substitutions or changes, should be covered by the protection scope of the present utility model.
