[0019] The present invention will be further described below with reference to the embodiments.

[0020] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0021] Please see Figs. 1-3This utility model provides a multi-channel control valve, including an outer channel housing 1 and four valve bodies 2 fixedly installed around the outer channel housing 1. A fluid inlet pipe 11 is fixedly connected to the top of the outer channel housing 1, and fluid outlet pipes 12 are fixedly connected to all four sides of the outer channel housing 1. The four valve bodies 2 are respectively connected to the four fluid outlet pipes 12. The surface of the fluid outlet pipes 12 is provided with external threads. Both ends of the valve bodies 2 are provided with threaded sleeves 21 that cooperate with the external threads. Through the arrangement of the outer channel housing 1, the fluid inlet pipe 11 and the fluid outlet pipes 12, in use, the threaded sleeves 21 of the four valve bodies 2 are respectively fitted onto the four fluid outlet pipes 12 to realize the connection between the valve bodies 2 and the fluid outlet pipes 12. After the fluid enters the outer channel housing 1 from the fluid inlet pipe 11, it is discharged into different pipes through the four valve bodies 2, realizing multi-channel control.

[0022] Reference Fig. 2 A removable filter screen 13 is fixedly installed on the inner wall of the outer channel housing 1 near each fluid discharge pipe 12. With the setting of the filter screen 13, when the fluid mixed with impurities enters the outer channel housing 1, the filter screen 13 will filter the impurities in the fluid, preventing the impurities from entering the valve body 2 with the fluid, and ensuring the sealing effect and flow effect of the control valve.

[0023] Reference Figs. 1-3 The outer channel housing 1 has a sliding scraper 14 inside, with brushes 17 fixedly connected around its perimeter. A screw 15 is rotatably mounted at one corner inside the outer channel housing 1, and one corner of the scraper 14 is fitted onto the screw 15 and threadedly connected to it. A motor 16 for driving the screw 15 is fixedly mounted on the top of the outer channel housing 1. Guide rods 18 are fixedly mounted at other triangular locations inside the outer channel housing 1, and the other triangular locations of the scraper 14 are slidably fitted onto the guide rods 18. Through the arrangement of the scraper 14, the motor 16 can be periodically started during use to drive the screw 15 to rotate, causing the screw 15 to drive the scraper 14 to slide along the guide rods 18, allowing the brushes 17 on the scraper 14 to clean the filter screen 13, preventing the filter screen 13 from becoming clogged and affecting its use.

[0024] The outer channel housing 1 is fixedly equipped with an openable top cover 19. The top cover 19 can be opened periodically to maintain the interior of the outer channel housing 1.

[0025] In addition, a drain valve 110 is fixedly installed at the bottom of the outer channel housing 1. By setting the drain valve 110, the drain valve 110 can be opened to discharge the impurities filtered in the outer channel housing 1.

[0026] The working principle and usage process of this utility model are as follows: First, during use, the screw sleeves 21 of the four valve bodies 2 are respectively fitted onto the four fluid discharge pipes 12 to achieve the connection between the valve bodies 2 and the fluid discharge pipes 12. After the fluid enters the outer channel housing 1 through the fluid inlet pipe 11, it is discharged into different pipes through the four valve bodies 2, realizing multi-channel control. When fluid mixed with impurities enters the outer channel housing 1, the filter screen 13 will filter the impurities in the fluid to prevent impurities from entering the valve bodies 2 with the fluid, thus ensuring the sealing and flow effects of the control valve. During use, the motor 16 can be started periodically to drive the screw 15 to rotate, causing the screw 15 to drive the spiral scraper 14 to slide along the guide rod 18, so that the brush 17 on the spiral scraper 14 can clean the filter screen 13, preventing the filter screen 13 from becoming clogged and affecting its use.
