[0002] A regulating valve, also known as a control valve, is a device used to adjust process parameters such as fluid flow, pressure, temperature and liquid level in industrial automation processes. It receives control signals output by a control unit and uses power operation to change the parameters of the medium to ensure precise control of the process flow.

[0045] The reciprocating screw rod 204 is provided with a transmission assembly, which is used to drive the reciprocating screw rod 204 to rotate;

[0050] When the inner cavity of the collection box 4 is filled with water and there is no storage space, the water passes through the filter screen body 209 and the arc baffle 2010 to the inner cavity of the other end of the water delivery box 3.

[0051] During this process, the impurities cleaned by the cleaning push plate 206 enter the inner cavity of the collecting box 4 through the discharge port 6 under the drive of the water flow, so that the impurities can be conveniently collected. When the impurities need to be processed, the collecting box 4 can be separated from the water tank 3 and the fixing plate 5 by removing the bolts, so that convenient centralized processing of the impurities can be achieved. After that, the collecting box 4 that has been cleaned of impurities is installed on the fixing plate 5 by bolts. At this time, the collecting box 4 can be sealed and docked with the water tank 3 through the sealing gasket, so that the impurities can continue to be collected.
