Logical, the connection of outlet conduit 4 is on shunt cylinder 9 and on the surface at 9 top of shunt cylinder, shunt cylinder 9 close to the surface of its bottom
It is communicated with fairlead 20, fairlead 20 is in the lower section of outlet conduit 4；Filtered water flows to shunt cylinder 9 after leakage hole
Interior, water is flowed out from outlet conduit 4 when normal filtration, and when being backwashed, water is flowed out from fairlead 20.The height of fairlead 20 is low
It in the height of outlet conduit 4 is directly flowed out from fairlead 20 in order to which when fairlead 20 is connected, water energy is enough, fairlead 20 is closed
Shi Shui is rushed to the outlet conduit 4 of top and is flowed out by outlet conduit 4.
The end of fairlead 20 is connected with valve 10, and the surface of valve 10 is fixedly connected with sewage pipe 13, and valve 10 is used for
Conducting and closing to fairlead 20, open valve 10, and water energy is enough to be flowed to sewage pipe 13 from fairlead 20 and be discharged, when closing, water
It can be discharged from outlet conduit 4, so as to be easily oriented to and controlled to water flow.
Fig. 1, Fig. 2, Fig. 3 and Fig. 8 are please referred to, the top of outer cylinder 1 is fixedly connected with upper cover 8, and 8 upper surface of upper cover, which opens up, to be passed through
It opens up through-hole and is connected with portable pillar 19, spring 18, the bottom of portable pillar 19 are fixedly connected between upper cover 8 and portable pillar 19
It is fixedly connected with lower platen 15, the upper surface of lower platen 15 offers through slot 17.Portable pillar 19 makes between portable pillar 19 and upper cover 8
With elastic force, so that portable pillar 19 has restoring force, the inner wall at the edge and outer cylinder 1 of lower platen 15 is wanted when being assembled
There is a preferable air-tightness, carries out in backwash process, it, can be to filter core when pressing portable pillar 19 lower platen 15 being made to move down
Water inside 6 generates a pressure, and the water inside filter core 6 can be towards swarming at through slot 17 at this time, and the movement of this part water is brought
Frictional force will carry out a backwash to filter core 6 corresponding at through slot 17, rotation portable pillar 19 keeps through slot 17 corresponding different
The filter core 6 in orientation, carries out repeated presses operation, can backwash to other parts filter core 6, and the water finally backwashed is from row
Dirty pipe 13 is discharged.The valves such as settable shut-off valve on outlet conduit 4.
