The water inlet 11 in road 1 enters, the hydraulic pressure of water inlet pressure gauge 12 and the monitoring water inlet 11 of water inlet pressure sensor 142；Now
Triple valve 41 is filter switch pattern, then current are entered by inflow filter 4 after intermediate conduit 2 by triple valve 41
Enter filter 42, filter 42 exports clear water after filtering out the impurity in water, and clear water is by entering outlet conduit after flowmeter 43
5, then by the clear water after the discharge filtering of delivery port 54, delivery port pressure gauge 52 and delivery port pressure sensor 511 detect
The hydraulic pressure at the mouth of a river 54.
The operation principle of backwash process：As shown in Figure 2 and Figure 4, linkage between flowmeter 43 and triple valve 41 be present to close
System, when filter 42 blocks, can be reduced to cause delivery port pressure gauge 52 and water outlet by the water-carrying capacity of filter 42
The hydraulic pressure that mouth pressure sensor 511 monitors reduces, and the gear of flowmeter 43 changes, and switches to backwash gear, triple valve
41 linkage changes turn to backwashing state, the closed electromagnetic valve in outlet conduit 5；Now other filters 42 are still filtration condition,
The clear water filtered in the filter 42 of filtration condition enters the filter 42 of backwashing state by outlet conduit 5, is recoiled
Washing procedure, sewage are discharged by blow-off line 3；After filter 42 is cleaned up, the water-carrying capacity increase of backwash, work as hydraulic pressure
Increase to a certain extent when, the gear in flowmeter 43 can return to filtering gear, and triple valve 41 changes on off state, into normal
Filtered model.
In the state change process for filtering and backwashing, the water hammer-resistant device 53 set at delivery port 54 can eliminate wink
Between the water hammer that is formed, protect the pipeline and connector in back-flushing filtering device.
Preferred embodiment of the present utility model is the foregoing is only, it is all in this practicality not to limit the utility model
Within new spirit and principle, any modification, equivalent substitution and improvements made etc., guarantor of the present utility model should be included in
Within the scope of shield.
