In the present embodiment, the first cover plate 3451 is fixedly connected with the second cover plate 3452, the second cover plate 3452 and second point of water Plate 353 is fixedly connected.

Preferably, in the present embodiment, sewage draining valve is pressure differential valve, the differential pressure signal transmission that driving switch is felt To sewage draining valve, control of sewage disposal valve is opened or closed.It should be noted that in this utility model other embodiment, blowdown Valve can be other any valves.In addition, driving switch can also be other electric drives switching or timing driving switch.

The present embodiment provide 300 operation principle of automatic cleaning strainer be, under normal circumstances, driving switch 341 , close to 0, in representing automatic cleaning strainer 300, strainability is good for first input block 3411 and 3413 pressure differential of the second input block It is good, but due in filter process booty can be stored in filter assemblies 330, make to cause water resistance phenomenon in filter assemblies 330, this When the first input block 3411 pressure can be higher than 3413 pressure of the second input block, when pressure differential reaches preset value, driving switch 341 Start working, by signal transmission to sewage draining valve 3193, sewage draining valve 3193 is opened, now the current meeting in filter assemblies 330 Entered in actuator 345 by fan-shaped water inlet 3453, current are discharged by discharge outlet 3455 along water-flowing trough 3454, current edge Actuator 345 is flowed out in parabolical direction, collides with 310 inwall of housing, using the principle of counteracting force, promotes actuator 345 Rotate, so as to drive from component 350 is washed and outlet pipe 311 is rotated together, carry out positive and negative from mutually conversion is washed, can will filter group Part 330 is cleaned up, and reaches good cleaning performance, and after cleaning is finished, driving switch 341 quits work.

The automatic cleaning strainer 300 that the present embodiment is provided, realizes in the case of without other power are provided, single Filter automatic sensing carries out positive and negative washing certainly and mutually changes, and the efficiency and performance that improve itself cleaning is also reduced and used into This.In sum, the present embodiment provide automatic cleaning strainer 300 not only increase filter efficiency reduce use cost and Also improve single itself cleaning performance of filtration.

Preferred embodiment of the present utility model is the foregoing is only, this utility model is not limited to, for this For the technical staff in field, this utility model can have various modifications and variations.It is all it is of the present utility model spirit and principle Within, any modification, equivalent substitution and improvements made etc. are should be included within protection domain of the present utility model.
