[0002] Cone valves are pipe accessories used to open and close pipelines, control flow direction, and regulate and control the temperature, pressure, and flow rate of the conveyed medium. Fixed cone valves are widely used in hydro-generator bypasses, dams, or other locations requiring water release, as well as in the middle sections of water pipelines for water treatment, municipal water distribution systems, reservoirs, petrochemical plants, power plants, and other applications. They control free discharge or continuous discharge flow.

[0003] Patent number CN215334784U discloses a fixed conical valve. The key technical features of the valve include a core tube and a flow deflector, and an electric device installed. The core tube is disposed within the flow deflector, a core opening is disposed on the side wall of the core tube, and a sleeve for closing the core opening is sleeved on the tube body. The sleeve is provided with a connecting block, which is provided with a connecting hole. The electric device is provided with a drive shaft, which is threadedly connected to the connecting hole. The electric device drives the drive shaft to rotate, and the drive shaft drives the connecting block to translate through the threaded connection with the connecting hole, thereby driving the sleeve to translate along the length of the core tube to open and close the core opening, thereby controlling the opening and closing of the valve. The drive shaft and the connecting block are screw-driven, and the driving force of the movable sleeve is large, capable of withstanding huge water pressure to smoothly open and close the valve.

When the sealing retaining tube 3 is away from the fixed disk 32, the pushing plate 24 is pulled by the second spring 25, so that the pushing plate 24 extracts the gas inside the sealing air cushion 22 to prepare for the next sealing.

[0052] Referring again to Figures 1, 2, 3, 4, 5, 6, 9, 10, 12, and 13, the cleaning assembly includes a plurality of baffles 48, each rotatably connected to the mounting cover 29.

When the filtered matter on the second filter plate 37 needs to be cleaned, the multiple first hydraulic telescopic rods 30 are started, and the multiple first hydraulic telescopic rods 30 pull the baffle 48 to deflect, so that water flows into the outer mounting frame 28. Then, the second hydraulic telescopic rod 33 is started, and the second hydraulic telescopic rod 33 drives the rotating disk 35 to rotate, so that the first filter screen 36 on the rotating disk 35 coincides with the filter screen on the connecting frame 34, and the water flows into the support tube 2 through the connecting frame 34.

[0055] Working principle: The two pipes are docked through the docking flange 31 and the docking frame 39. The liquid enters the support tube 2 through the mounting cover 29, flows out through the gap between the support tube 2 and the fixed plate 32, and then flows to the other pipe through the rotating frame 40.
