[0001] The present invention relates to the field of valve technology, and in particular to an adjustable valve and an implementation process thereof. Background Art

[0002] The valve is an important control part in the fluid conveying system, which can control the flow rate, pressure, flow direction and other aspects of the internal fluid. Through the search of the prior art, it was found that the Chinese patent with the announcement number CN112984136A discloses a valve with a residue discharge mechanism and its implementation method. The residue in the valve seat can be scraped off and discharged into the water outlet channel by a rotating scraper. Under the impact of the water flow, the residue is discharged with the water flow, avoiding the accumulation of residue in the valve seat and causing the gate to stick to the valve seat.

[0003] The inside of the valve can be cleaned without disassembling the valve, which is convenient for later maintenance. However, it is worth considering that the residue discharge mechanism has been located inside the valve. The arrangement of the residue discharge mechanism will affect the delivery of the fluid, and the valve plate needs to be in an open state during the process of the residue discharge mechanism cleaning impurities. The valve can no longer control the delivery of the fluid, which has certain limitations.

[0004] Therefore, in order to solve the above problems, a related facility that better meets the usage requirements is needed. Summary of the invention

A movable seat 15 is in contact with the top of the protective shell 13. The top end of the support portion 17 penetrates through the rectangular hole 21, and the top end of the support portion 17 is fixedly connected to the movable seat 15. A guide plate 20 is fixedly connected inside the protective shell 13, and the guide plate 20 penetrates through the support portion 17. A driver adapted to the first rotating shaft 16 is installed on the movable seat 15. A horizontal positioning member adapted to the protective shell 13 is installed on the movable seat 15. The driver includes a servo motor 22 fixedly installed on the top of the movable seat 15. The output end of the servo motor 22 is fixedly connected to a first bevel gear 23 located inside the protective shell 13. A second bevel gear 24 engaged with the first bevel gear 23 is fixedly sleeved on the outer portion of the first rotating shaft 16. A handle 31 located outside the protective shell 13 is fixedly installed on the worm shaft 14. The horizontal positioning member includes iron plates 25 respectively fixedly installed on both sides of the movable seat 15. A positioning plate 27 penetrates through the iron plate 25. A magnet block 26 is fixedly connected to the top of the positioning plate 27, and the bottom of the magnet block 26 is in contact with the top of the iron plate 25. Six positioning holes 28 are opened on the top inner wall of the protective shell 13, and the bottom end of the positioning plate 27 is located inside the corresponding positioning hole 28. A sealing ring 29 is fixedly sleeved on the outer portion of the valve plate 10, and the sealing ring 29 is in contact with the inner wall of the control passage 7. A sealing sleeve 30 is fixedly sleeved on the outer portion of the valve body 6, and the sealing sleeve 30 is in contact with the inner wall of the valve housing 1;When it is necessary to synchronously control the rotation of two valve plates 10, the servo motor 22 drives the first bevel gear 23 to rotate. The first bevel gear 23 drives the first rotating shaft 16 and the insertion block 18 to rotate through the second bevel gear 24. The insertion block 18 can drive the valve rod 11 and the valve plate 10 to rotate through the worm 14 and the worm gear 12, and control the fluid through the valve plate 10. When it is necessary to clean the control channel 7, the valve body 6 is driven to rotate by 90 degrees through the control locking unit, so that one of the control channels 7 communicates with the water inlet pipe 2 and the water outlet pipe 3. At this time, the magnet block 26 and the iron plate 25 are magnetically attracted to each other, and the bottom end of the positioning plate 27 is located in the corresponding positioning hole 28. The staff drives the magnet block 26 and the iron plate 25 to move upward, so that the bottom end of the positioning plate 27 is separated from the corresponding positioning hole 28. The staff drives the movable seat 15 and the iron plate 25 to move horizontally. The movable seat 15 drives the first rotating shaft 16 and the insertion block 18 to move horizontally through the support portion 17, so that the end of one of the insertion blocks 18 is completely inserted into the corresponding slot 19, and the other insertion block 18 is completely separated from the slot 19. At this time, the bottom end of the positioning plate 27 is located above the corresponding positioning hole 28.

When it is necessary to control the rotation of the unused valve plate 10, the staff drives the worm 14 without the insertion block 18 in the slot 19 to rotate through the handle 31, and the worm 14 can drive the unused valve plate 10 to rotate, and the opening and closing of the unused control channel 7 can be controlled alone, so as to facilitate the cleaning of the unused control channel 7. Through the design of the sealing ring 29, when the valve plate 10 closes the control channel 7, the sealing performance at the connection between the valve plate 10 and the control channel 7 is increased. Through the design of the sealing sleeve 30, the sealing performance at the connection between the valve body 6 and the valve housing 1 is increased, and it is avoided that the fluid enters the gap between the valve housing 1 and the valve body 6.;

When the position of the valve body 6 is adjusted, the staff drives the bolt 34 to rotate so that the top of the bolt 34 is screwed into the threaded sleeve 35 again, so as to avoid the chassis 33 and the second rotating shaft 32 from rotating relative to the valve housing 1, and the locking of the valve body 6 is completed again. According to actual needs, the valve body 6 can be driven to rotate relative to the valve housing 1, thereby changing the position of the control channel 7, realizing the single and double control of the valve, and facilitating the cleaning of the unused control channel 7.

The design of the slider 40 and the slide groove 39 prevents the first mounting portion 37, the arc plate 36 and the connecting pipe 4 from shaking in the vertical direction relative to the valve housing 1. The stopper 41 is located on the side of the second mounting portion 38 away from the first mounting portion 37, thereby preventing the slider 40 from being separated from the slide groove 39.
