Envelope, the filtering medium layer foldable integral into continuous W shapes ring-type and be arranged between the inner support cylinder and outer support cylinder, institute
Stating filtering medium layer includes intermediate layer and protective layer, and the both sides in the intermediate layer are laminated respectively and are provided with one layer of protective layer, institute
It is politef microfiltration film layer to state intermediate layer, is densely covered with filtration through hole on the inner support cylinder, the barrel of outer support cylinder, and which is special
Levy and be：The protective layer is politef protective layer, and the politef protective layer is latticed.
Further, also offer end on the top side face of the outer support cylinder, bottom side face respectively and filter through hole.
Further, the filtering medium layer is overall at least by two circulus welding for being folded into continuous W shapes
Into.
Further, the upper end cover is provided with the positioning flaps of an annular, and the bottom of the bottom end cover is provided with and connects
Mouth pipe fitting.
Further, bag fluorine O-ring is provided with the periphery of the interface pipe fitting.
Further, the inner support cylinder, connection is respectively welded between outer support cylinder and upper end cover, bottom end cover.
Further, the inner support cylinder is politef support tube.
Further, the outer support cylinder is politef support tube.
The beneficial effects of the utility model are：The protective layer of its filtering medium layer is protected for latticed politef
Layer, which can greatly improve the corrosion resistance of filtering medium layer, improve the service life of filter element；While latticed protective layer energy
It is enough effectively to reduce and as the friction damage between the politef microfiltration layer in intermediate layer, therefore can further extend making for filter element
Use the life-span；Additionally, by offering filtration through hole on the top side face of outer support tube, bottom side face, being capable of preferably moistening
The filtering medium layer at both ends, increases pollutant holding capability, so as to improve filter efficiency.
