Detailed Description

The following description will further describe embodiments of the present invention with reference to the accompanying drawings and examples. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.

As shown in fig. 1-3, a multifunctional control valve comprises a valve body 1 and a filter screen 3, wherein the valve body 1 is provided with a water inlet channel 2 and a water outlet channel, the valve body 1 is provided with a valve plate (not shown) for opening and closing the water inlet channel 2 and the water outlet channel, one end of the filter screen 3 is rotatably arranged in the valve body 1 through a rotating shaft 5 and is located in the water inlet channel 2, the inner wall of the water inlet channel 2 is fixedly provided with a blocking block 4 for preventing the filter screen 3 from excessively overturning, the free end of the filter screen 3 is abutted against the blocking block 4, the valve body 1 is further provided with a limiting device for limiting the rotation of the filter screen 3, the limiting device comprises a hexagonal rotating handle 6, one end of the rotating shaft 5 penetrates out of the valve body 1, the rotating handle 6 is fixedly sleeved on the rotating shaft 5, and a hexagonal groove 7 is arranged on the valve body 1 at the position of the rotating handle 6, the rotating handle 6 is sleeved with a hexagonal sleeve 11 matched with the shape of the rotating handle 6, and the hexagonal sleeve 11 is arranged in the hexagonal groove 7 in a penetrating mode.

In order to prevent the hexagonal sleeve 11 from being separated from the hexagonal groove 7 and enable the filter screen 3 to always resist against the blocking block 4 for filtering, a first magnetic block is fixedly arranged in the hexagonal groove 7 of the valve body 1, and a second magnetic block which is magnetically attracted with the first magnetic block is arranged in the hexagonal sleeve 11.
