Number in the figure is:

1. pressure-reducing valve, 2. water inlet pipe, 3. three-way cock valve, 4. scavenge pipe, 5. adjutage, 6. discharging valve, 7. locular wall, 8. collecting chamber, 9. hollow fiber bundle partiting leaching plate catchment, 10. air bleeding valve, 11. filter locular walls, 12. doughnuts, 13. the filter chamber, 14. blow-off pipes, 15. sewage draining valves, 16. miillpore filter, 17. protecting wire nets.

In conjunction with the accompanying drawings the utility model is specified:

Accompanying drawing provides the filter chamber of two kinds of filter materials, is replenishing No. 91219459.6 application case content.Filter material of the present utility model can also adopt other form certainly, activated carbon for example, sand filtration or the like.The structure branch of filter chamber is seen Fig. 1 .1, Fig. 2 .1.Filter chamber's structure of Fig. 3, Fig. 4 is compound, but each cellular construction and Fig. 1 .1, Fig. 2 .1 is identical.The doughnut filter chamber makes filter material by the doughnut 12 that a branch of two-port is cemented on the partiting leaching plate 9.Partiting leaching plate 9 connects with filter chamber's 13 sealings, and doughnut 9 is in the filter chamber 13, and both ends open then is among the collecting chamber 8 of filter plate 9 opposite sides.On the wall 11 on 13 tops, filter chamber, be provided with a drain tap 10.External pure water pipe 5 has water purification valve 6 on the wall 7 of collecting chamber 8 on the pure water pipe 5, and the utility model characteristic is to use 3 one scavenge pipes 4 of tee pipe fitting on upstream water inlet pipe 2, sees Fig. 1 .1, Fig. 2 .1.Manage the water side UNICOM of 4 downstream and filter chamber, be connected in the accompanying drawing on the outlet pipe 5.Blow-off pipe 14 is below the filter chamber, and there is sewage draining valve 15 its bottom.This routine using method is valve 3 conducting water inlet pipes 2 and filter chamber 13 during filtration, blanked-off pipe 4 and blowoff valve 15.First use should be opened air bleeding valve 10 to make in the filter chamber 13 earlier and is full of water, shuts valve 10 again.Open valve 6 during water and can emit water purification.The method of cleaning filter material is a conducting scavenge pipe 4, closes the passage of water inlet pipe 2 and filter chamber, shuts valve 6, opens the sewage after sewage draining valve 15 is emitted cleaning.Adopt the filter chamber structure of film filter material slightly to change; Film 16 replaces doughnut 12, is protective film 16, adds a protecting wire net 17 in its both sides.Using method is identical with the doughnut filter chamber.Accompanying drawing 3, accompanying drawing 4 provide another kind of preferred embodiment.It is characterized in that adopting the filter chamber of composite construction.By two

unit filter chamber

13a, 13b one be combined into, common collecting chamber 8 is arranged, there are independent water inlet and blow-off pipe 14a, 14b in each filter chamber unit, and each water inlet pipe is supplied water by common water inlet manifold 2.Establish threeway plug valve 3 in water distribution place.Each

filter chamber

13a, 13b water inlet pipe all-pass were closed sewage draining valve 15a, 15b when using method was water, and water purification valve 6 is emitted water purification.When cleaning filter material, implement locellus and clean,

filter chamber

13a or 13b water inlet pipe that desire is cleaned are closed, and valve-off 6 is opened the sewage draining valve 15a or the 15b of this filter chamber again, discharges cleaning sullage.The embodiment of composite construction also has two advantages, at first is that water for cleaning is the clean water through filtering, and secondly is for water purification the time, does not have unnecessary detergent line 4, and structure is more reasonable.The filter material that each embodiment of the utility model is used when for example being doughnut, microporous membrane, can be regulated hydraulic pressure by the withstand voltage situation of material, adds a pressure regulator valve 1 on inlet pipeline.Agent structure of the present utility model comprises filter chamber, blow-off pipe, water inlet pipe, scavenge pipe or multiple-unit filter chamber, but the equal integral production of plug valve becomes a whole drinking water purifier that can directly be contained on the pipeline.
