Specific embodiment

It is described in detail below in conjunction with feature and principle of the attached drawing 1-4 to the utility model, illustrated embodiment is only used for It explains the utility model, the protection scope of the utility model is not limited with this.

As shown in Figs 1-4, which includes main water supply pipe 1, supervisor when main water supply pipe 1 is normal water supply Road.Main water supply pipe 1 be equipped with filtering subsidiary conduit 2, the both ends of subsidiary conduit be connected on main water supply pipe and It is connected to main water supply pipe.Subsidiary conduit is equipped with filtering module 3, and filtering module includes inlet end 31 and water outlet end 32, Filtering module 3 is detachably arranged on subsidiary conduit 2.Inlet end 31 and water outlet end 32 pass through flange and auxiliary tube respectively Road is detachably connected, and junction is equipped with gasket.

Filtering module includes tube body, and filter screen is equipped in tube body, and tube body both ends are connect by flange with subsidiary conduit, and Gasket is equipped between tube body and subsidiary conduit.Filter screen is MULTILAYER COMPOSITE filter net sheet, and filter screen is stainless steel material.

Subsidiary conduit 2 is connect by flushing pipe with the flush box 4 of backwash and tie point is located at filtering module Water outlet end side is located at filtering module inlet end side on subsidiary conduit and is equipped with backwashing water drainage pipeline 5.

Main water supply pipe between subsidiary conduit and main water supply pipe tie point is equipped with first switch valve 8, main-supply Road is connect by moisturizing pipeline 6 with replenisher tank 7 and tie point is located at after first switch valve 8；One end of subsidiary conduit water inlet is set Have a second switch valve 9, one end of water outlet is equipped with third switch valve 10, and second switch valve is equipped with timer, second switch valve with Third switch valve is opened simultaneously/is closed.
