The convex necked butt-welded flange, through the setting of the adjusting mechanism, when the water flow needs to be controlled, first turn the nut, the nut turns outward, the locking effect of the threaded rod disappears, and the extrusion effect on the first gear also disappears, and then turn the rotating block, the rotating block drives the rotating shaft to rotate, and drives the second gear to rotate, the rotation of the second gear drives the first gear to rotate, the first cover plate and the second cover plate move to both sides and enter the movable groove, when it is opened or reduced to the required size, turn the nut until it is tightened, the nut squeezes and fixes the first gear, thereby completing the regulating effect of the convex necked butt-welded flange on the water flow.

[0004] The convex necked butt-welded flange disclosed in the above document has the following defects: the technical solution cannot automatically clean the filter plate, so that even if a small amount of debris blocks the filter hole, the entire plate must be disassembled for cleaning.

[0005] It can be seen from this that the existing convex neck butt welding flange does not have a good cleaning component, and it is necessary to improve the existing deficiencies and provide a convex neck butt welding flange. Utility Model Content

[0006] The utility model aims to provide a convex neck butt welding flange to solve the problems raised in the above background technology.

[0013] Furthermore, a second spring is fixedly installed inside the installation groove, and an anti-slip gasket is fixedly installed on one end of the second spring.

[0014] The utility model has the following beneficial effects:

[0015] (1) When water flows, the impact force of the water flow will push the blades to rotate. When the blades rotate, the rotating rod drives the bearing to rotate. The bearing rotates to rotate the rotating rod. The rotation of the rotating rod drives the first connecting rod to rotate. The rotation of the first connecting rod drives the second connecting rod to rotate. The rotation of the second connecting rod drives the mounting plate to rotate. The rotation of the mounting plate drives the cleaning brush to clean the surface of the filter screen, so as to avoid the situation where a small amount of debris blocks the filter hole and the entire filter screen needs to be disassembled for cleaning.

[0016] (2) The utility model installs the fixing ring into the inner wall of the flange block, and then the fixing ring squeezes the arc-surface block into the interior of the groove. The arc-surface block drives the slider to move, and the slider drives the first spring to contract, so that the arc-surface block enters the interior of the groove. When the groove and the arc-surface block overlap, the first spring rebounds and connects the arc-surface block into the interior of the groove, and the installation is completed. When disassembling, the fixing ring is pushed upward to make the arc-shaped surface contact with the slider, and the fixing ring can be removed. The filter structure is convenient and quick to disassemble and install, thereby improving practicality.

[0017] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
