To achieve the above object, the utility model uses following technical scheme：
Automatic backwashing filter, it is characterised in that including valve body, valve rod and butterfly plate, passage is provided with the valve body,
And the valve body is provided with water inlet, delivery port and sewage draining exit, the valve body and is provided with screen pack, the butterfly plate is located at described
Screen pack inner chamber, one end of the valve rod is embedded in the valve body.
Its further technical scheme is：The top of the valve body is provided with top-portion apertures, and the bottom of the valve body is provided with base apertures,
The lower end of the valve rod is embedded in the base apertures, and the upper end of the valve rod passes through the top-portion apertures, and extends to the valve
In vitro.
Its further technical scheme is：Sealing ring is provided between the top-portion apertures of the valve rod and the valve body.
Its further technical scheme is：The upper end of the valve body is connected with regulation handle.
Its further technical scheme is：The screen pack is cylindrical.
Its further technical scheme is：Inner bag balance bracket and side plate, the screen pack insertion are provided with the valve body
Between inner bag balance bracket and side plate.
Its further technical scheme is：The water inlet is located on same axis with the delivery port, the sewage draining exit position
In in the vertical direction of the water inlet and the axis of the delivery port.
The beneficial effect of the utility model compared with prior art is：Automatic backwashing filter of the present utility model, leads to
Cross to be provided with valve body in water inlet, delivery port and sewage draining exit, and valve body and be provided with screen pack, the screen pack inner chamber is provided with butterfly
Plate, blowdown whole process is realized by a regulation handle operation, simple and convenient, reduces the work difficulty of operator.
The utility model is further described with specific embodiment below in conjunction with the accompanying drawings.
Brief description of the drawings
The cutting structural representation for the backwash filter that Fig. 1 provides for the utility model specific embodiment；
Fig. 2 is mplifying structure schematic diagram at Fig. 1 A.
Embodiment
In order to more fully understand technology contents of the present utility model, with reference to specific embodiment to skill of the present utility model
Art scheme is further described and illustrated, but is not limited to this.
Specific embodiment as shown in Figure 1 to Figure 2, the automatic backwashing filter that the present embodiment is provided, including valve body 1,
Passage is provided with valve rod 4 and butterfly plate 11, valve body 1, and valve body 1 is provided with water inlet 3, delivery port 8 and sewage draining exit 10, valve body
Screen pack 2 is provided with 1, butterfly plate 11 is located at the inner chamber of screen pack 2, and one end of valve rod 4 is embedded in valve body 1,
Further, the top of valve body 1 is provided with top-portion apertures, and the bottom of valve body 1 is provided with base apertures, and the lower end of valve rod 4 is embedding
Enter in the base apertures, the upper end of valve rod 4 passes through top-portion apertures, and extends to outside the valve body 1.
In the present embodiment, the lower end of valve rod 4 is embedded in the base apertures, and using the bottom of nut 13 and the valve body 1
Portion is fixed.
Sealing ring 5 is provided between the top-portion apertures of valve rod 4 and valve body 1, it is to avoid valve rod 4 seepage occurs during operation,
Improve overall sealing.
Further, the upper end of valve body 1 is connected with regulation handle 6, by the rotation of regulation handle 6, so as to drive valve
The rotation of body 1, with the switching for the state for realizing normal work and cleaning screen pack 2.
In the present embodiment, screen pack 2 is cylindrical；Certainly, in other embodiment, above-mentioned screen pack 2 can be in side
Shape.
Be provided with inner bag balance bracket 7 and side plate 9 in valve body 1, screen pack 2 be embedded in inner bag balance bracket 7 and side plate 9 it
Between, the space to be formed is enclosed between inner bag balance bracket 7 and side plate 9, the installation to screen pack 2 serves the effect of positioning.
In addition, above-mentioned side plate 9 is located at the both sides of the sewage draining exit 10, so that when rinsing, sewage will not be from delivery port 8
Place's discharge.
In the present embodiment, water inlet 3 is located on same axis with the delivery port 8, and the sewage draining exit 10 is located at described
