When the valve body is in use, the staff adjusts the water flow inside the valve body through the controller. When water flows through the filter screen inside the installation frame, the filter screen filters impurities in the water. At the same time, the water flow drives the fan blades and the rotating rod to rotate, and the rotating rod carries the cleaning plate to clean the surface of the filter screen to avoid impurities from accumulating on the filter screen. The filtering device achieves the effect of filtering impurities in the water inside the valve body, avoiding impurities in the water from blocking the valve body, thereby affecting the normal use of the valve body.

[0014] The effect achieved by the above components is: after the staff inserts the installation frame into the reserved hole, the staff moves the pad, and the pad carries the insertion rod through the fixed frame and is inserted into the socket of the fixed plate, thereby achieving the effect of fixing the fixed plate and the installation frame, preventing the filter from shaking inside the valve body.

[0015] Preferably, a pointed protrusion is fixedly connected to one end of the insertion rod, and the tip of the pointed protrusion is away from the insertion rod.

[0016] The effect achieved by the above-mentioned components is that the pointed protrusions are provided to facilitate the staff to insert the insertion rod into the insertion hole of the fixing plate, thereby bringing convenience to the staff.

[0018] The effect achieved by the above components is: by setting the pull rope, the maximum displacement of the pad and the insertion rod is limited, thereby preventing the insertion rod from falling when not in use.

[0019] In summary, the beneficial effects of the utility model are:

[0020] Before the valve body needs to be used, the staff first moves the fixing plate, and the fixing plate with the installation frame is inserted into the reserved hole of the valve body, and finally the fixing plate fits the valve body. When the valve body is in use, the staff adjusts the water flow inside the valve body through the controller. When water flows through the filter net inside the installation frame, the filter net filters the impurities in the water. At the same time, the water flow drives the fan blades and the rotating rod to rotate, and the rotating rod carries the cleaning plate to clean the surface of the filter net to avoid the accumulation of impurities on the filter net. The filtering device achieves the effect of filtering impurities in the water inside the valve body, avoiding the impurities in the water blocking the valve body, thereby affecting the normal use of the valve body.

At the same time, the water flow drives the fan blades 57 and the rotating rod 56 to rotate, and the rotating rod 56 carries the cleaning plate 58 to clean the surface of the filter screen 52 to avoid impurities from accumulating on the filter screen 52. The filter device 5 achieves the effect of filtering impurities in the water inside the valve body 1, and prevents the impurities in the water from blocking the valve body 1, thereby affecting the normal use of the valve body 1.

[0027] Reference Figure 1-4 As shown, a handle 511 is fixedly connected to the surface of the fixed plate 53, and the surface of the handle 511 is provided with anti-slip grooves.
