The control valve on control valve and outlet pipe on the water inlet pipe is fixed on water inlet pipe by flange respectively and goes out
On water pipe.
Control valve is provided on the backwash water inlet pipe and backwash outlet pipe.
During normal filtration, the control valve on water inlet pipe and outlet pipe is kept to be in opening state, water entered from water inlet pipe
Then filter chamber is flowed into static pressure water filtering barrel, is entered in cylindrical filtration through the filter hole on cylindrical filtration, Ran Houcong
Outlet pipe flows out；When carrying out back flush, the control valve on water inlet pipe and outlet pipe is kept to be closed, backwash water inlet
Control valve on pipe and backwash outlet pipe is in opening state, and water enters outlet pipe from backwash water inlet pipe, through cylindrical mistake
Strainer enters filter chamber, then through backwashing outlet pipe outflow.
The utility model is prepared using anti-corrosion material, reduces pipeline corrosion, and extend filter uses the longevity
Life；Strong magnetic iron bar, magnesium stick, copper filter screen is respectively adopted in self-filtering material, prolongs the service life, and reduces replacement frequency
Rate；Using galvanized pipe and copper filter screen, it is easier to rinse well the impurity accumulated in filter chamber in backwash process.
The utility model realizes high pressure backwash, can thoroughly remove the impurity of filter screen retention, ensure filter efficiency,
Service life is long, and repair and replacement frequency is low, extend underground spraying, sprinkler tip service life.
