[0002] The regulating valve, also known as the control valve, is a key component in the field of industrial automation process control. It receives the control signal output by the regulating control unit and uses power operation to change the flow, pressure, temperature, liquid level and other process parameters of the medium (such as gas, liquid, etc.). The regulating valve is generally composed of two parts: the actuator and the valve. It is an important tool for realizing industrial automation control.

[0003] According to a high-precision energy-saving flow control valve disclosed on the patent website (authorization announcement number: CN 113639091B), "the present invention relates to the field of valve technology, specifically a high-precision energy-saving flow control valve, including a main valve, a branch valve pipeline, a stop valve, a support frame, and a valve stem. It is driven by a hydraulic cylinder so that the valve plate can cut off the fluid in the pipeline, thereby improving the ability of the flow control valve to regulate and control the fluid in the pipeline. By using the valve plate to cut off the fluid in the pipeline, the main valve of the pipeline does not need to be closed when replacing parts and maintaining the valve, thereby further improving the convenience of using the flow control valve. At the same time, by using the valve plate to cut off the fluid in the pipeline, the flow control valve has a stronger load and regulation ability, thereby improving the scope of use of the high-precision energy-saving flow control valve. By dividing the control valve into two branch valve pipelines and a main valve, the control valve is more convenient to disassemble, thereby improving the convenience of carrying and installing the control valve."

[0034] See also Figures 1 to 10 On the basis of the first and second embodiments, the cleaning mechanism 7 further comprises a fixed frame 71, the fixed frame 71 is fixedly connected to the outside of the filter box 8, a sealing plate 72 is movably connected inside the fixed frame 71, a support arm 73 is fixedly connected to the outside of the sealing plate 72, a connecting plate 701 is fixedly connected to the outside of the filter box 8, a threaded plate 75 is fixedly connected to one side of the support arm 73, a threaded rod 76 is threadedly connected inside the threaded plate 75, a worm gear 77 is fixedly connected to the outer wall of the threaded rod 76, a worm 78 is meshed with the outer ring of the worm gear 77, an L-shaped block 79 is fixedly connected to the outside of the filter box 8, and a fixed sleeve 74 is fixedly connected to the outside of the filter box 8, so as to facilitate the cleaning of impurities filtered inside the filter box 8 and achieve good efficiency.

[0035] Furthermore, a rotating hole three is provided inside the L-shaped block 79, and the worm 78 passes through the rotating hole three and rotates. One end of the worm 78 is fixedly connected to a hand wheel, so that the worm 78 can be driven to rotate by the hand wheel.

[0036] Furthermore, a rotating hole four is opened inside the connecting plate 701, and the threaded rod 2 76 passes through the rotating hole four and rotates, the support arm 73 is slidably connected to the inner wall of the fixing sleeve 74, and a rectangular opening is opened on the outside of the fixing frame 71, and the support arm 73 is movably connected to the inner wall of the rectangular opening to stably support the threaded rod 2 76.

[0037] Furthermore, the sealing plate 72 is movably connected to the outside of the filter box 8 , and the threads of the outer walls at both ends of the threaded rod 76 are in opposite directions, so that the rotational motion of the threaded rod 76 is converted into the linear motion of the threaded plate 75 .

[0038] In actual operation, when the device is used, the fluid is first transported to the interior of the filter box 8 through the water inlet pipe 4. At this time, the impurities contained in the fluid can be filtered and purified under the filtering effect of the filter screen 9. At this time, the motor 52 can be started to work, and the output end of the motor 52 can drive the output shaft 53 to rotate. The output shaft 53 can drive the movable block 54 to make a circular motion along the axis point of the output shaft 53, and the movable block 54 will also drive the short shaft 55 to move. Since the short shaft 55 moves inside the slot block 56, the short shaft 55 will push the slot block 56 to move. Since the output shaft 53 is in a continuous rotation state, the short shaft 55 can push the slot block 56 to move forward and backward. At this time, the slot block 56 can drive the rack 58 to move forward and backward through the support frame 57. The movable gear 59 is in a meshing relationship, so the rack 58 can push the transmission gear 59 to rotate, and the transmission gear 59 can drive the driving shaft 510 to rotate. The driving shaft 510 drives the threaded rod 516 to rotate through the transmission of the driving component 511, the long shaft 513 and the belt structure 515. Since the threaded rod 516 and the cleaning plate 517 are threadedly connected, and the limit block 518 can slide and limit on the outer wall of the sliding rod 519, the rotational motion of the threaded rod 516 can be converted into a linear motion of the cleaning plate 517. The cleaning plate 517 can reciprocate back and forth, and then the impurities filtered on the right side of the filter screen 9 can be scraped and cleaned, the filter screen 9 can be cleaned and prevented from being blocked, and the impact on the fluid transportation can be reduced. While achieving filtration, the stability of the fluid transportation process is also guaranteed.

[0039] When the groove block 56 reciprocates back and forth, the groove block 56 will also drive the fixed cylinder 62 to reciprocate through the connecting seat 61. At this time, since both sides of the driving shaft 65 and the stopper 601 are set with inclined surfaces, when the driving shaft 65 contacts the stopper 601, the driving shaft 65 will be pushed to move upward, and the driving shaft 65 can drive the circular plate 64 to slide upward on the inner wall of the fixed cylinder 62 and compress the spring 63. When the driving shaft 65 does not contact the stopper 601, the spring 63 in a compressed state can push the circular plate 64 to move downward, and the circular plate 64 can drive the driving shaft 65 to move downward to vibrate and knock the top of the filter box 8, so that the filter screen 9 can vibrate, so that impurities stuck to the right side of the filter screen 9 can be detached, so that the cleaning plate 517 can better perform the cleaning operation, and at the same time, a good cleaning effect can be achieved, which is convenient for the impurity cleaning work to be better carried out.

[0040] The worm 78 and the worm gear 77 are meshed, so that the worm 78 can drive the threaded rod 76 to rotate through the worm gear 77. Since the threaded rod 76 and the threaded plate 75 are threadedly connected, and the support arm 73 can slide and limit inside the fixed sleeve 74, the support arm 73 can drive the sealing plate 72 to move, so that the sealing plate 72 can move away from the filter box 8. At this time, the cleaning port opened in the filter box 8 can be leaked, thereby facilitating the cleaning operation of the filtered impurities. While achieving the cleaning purpose, the sealing plate 72 can seal the inside of the filter box 8, which is convenient for the fluid to be better transported. At the same time, good disassembly efficiency can also be achieved, further improving the convenience during the disassembly and cleaning process, reducing the time spent by the staff during the disassembly and cleaning process, and enhancing the practicality of the device.
