Brief description of the drawings
In order to further illustrate the utility model, further describe below in conjunction with accompanying drawing:
Fig. 1 is the structural representation of embodiment 1;
Fig. 2 is the structural representation of embodiment 2;
Fig. 3 is the structural representation of embodiment 3; Wherein: 1. flange; 2. pressure transmitter; 3. stainless steel filtering net; 4. current deflecting valve; 5. housing; 6. YE; 7. switch board; 8. electric butterfly valve; 9. blowoff valve; 10. floss hole.
Detailed description of the invention
Below in conjunction with accompanying drawing, embodiment of the present utility model is described, embodiment does not form restriction of the present utility model:
In conjunction with Fig. 1, embodiment 1;
Backwash filter, it is characterized in that, comprise housing 5, described housing one side comprises flange 1, the pipeline that described flange connects is in housing 5 inside, described pipeline is stainless steel filtering net 3, be flange connect pipeline on have very much filter opening, current deflecting valve 4 is installed on described housing, current deflecting valve 4 comprises the circular slab on vertical bar and vertical bar, and described circular slab is positioned at stainless steel filtering net 3, and pipeline is stretched out in described stainless steel filtering net 3 ends, pipeline stretches out outside housing 5, described in comprise blowoff valve on the pipeline that stretches out.The technique effect of the essence that the technical scheme at this place plays is to facilitate filtration for water, and treating capacity is large, can self-cleaning blowdown, and uninterruptedly supply water, application surface is extensive.
Described current deflecting valve 4 is electrically operated valve.The technique effect of the essence that the technical scheme at this place plays is to realize outside opening and closing.
In conjunction with Fig. 2, embodiment 2, described stainless steel filtering net 3 ends are undergauge structure, the outer wall of described stainless steel filtering net 3 is tilted shape.The technique effect of the essence that the technical scheme at this place plays is that dirt has certain gravity flow effect, can conveniently dirt be discharged.
Described shell end is provided with electric butterfly valve 8.The technique effect of the essence that the technical scheme at this place plays is that electric butterfly valve 8 starts conveniently, and effectively opening and closing, provide more powerful adjustment function.
The net of described stainless steel filtering net 3 has two-layer, and skin is sleeved on internal layer.The technique effect of the essence that the technical scheme at this place plays is the effect that can realize multiple filtration, plays different filtration situations according to different situations.
The end of described stainless steel filtering net 3 also comprises floss hole 10 upward.The technique effect of the essence that the technical scheme at this place plays is, after preventing that screen pack from blocking, to cause hydraulic pressure to discharge, and can play the effect discharging water.
