Below in conjunction with accompanying drawing, further set forth concrete structure of the present utility model.

With reference to Fig. 1,2, in the disinfectant box 1 of efficient germicide is housed, its water inlet end links by waterpipe jointing 20 and running water pipe, and the water side is connected with combination valve 3, and combination valve 3 is installed on the loam cake 21 of

cleaner

2,22 is the rotary handle of

combination valve

3,23 is water output duct, and 24 is the delivery port joint, and 25 is the sewage draining exit joint, 26 is the cleaner lower cover, and 27 is the waterstop pad circle.The structure of the disinfectant box 1 of dress efficient germicide wherein, belong to prior art, can adopt concrete structure or other structure shown in the Chinese patent (No. 89218266), the germicide containing triiodo resin that its efficient germicide can use Fuzhou City Kodak purification of water quality research institute to produce.

With reference to Fig. 3, the valve pocket 4 of combination valve is that cylindrical cavity 6 outer rectangular cylindrical body are arranged in a kind of, on three square faces of cylindrical body and be through to having respectively of cylindrical cavity 6: water inlet 7 and delivery port 8,9, sewage draining exit 10 and connect filter mouthfuls 11,12.6 one of described cylindrical cavities open wide, the other end sealing.

The valve pocket 4 of combination valve with the annexation of above-mentioned relevant member is: the square face with water inlet 7 is connected with the water side of disinfectant box 1; Having the square face that connects filter mouth 11,12 is connected with Upper Lid of Filter 21; Delivery port 8 is connected with water output duct 23; Delivery port 9 is connected with delivery port joint 24; Sewage draining exit 10 is connected with sewage draining exit joint 25.

With reference to Fig. 4, valve shaft 5 is a kind of circular cylindrical shape bodies, on three different sections and mutually perpendicular diameter of column, respectively has several limberss, and

limbers

13,14,15 is wherein arranged on a section; Limbers 16,17,18 is arranged on another section, and another has limbers 19 on the section.And limbers 13,14 communicates; Limbers 15,16 communicates; Limbers 17,18,19 communicates.End at valve shaft 5 is installed rotary handle 22.Long and chamber directly adapts with the chamber of cylindrical cavity 6 shown in Figure 3 for the length of valve shaft 5 and circle footpath.Valve shaft 5 is set in the valve pocket 4, twisting rotary handle 22, each limbers on the valve shaft 5 can be respectively with valve pocket on water inlet, delivery port, connect a filter mouthful corresponding communication.

With reference to Fig. 5, the shell of cleaner 2 is to be made of loam cake 21 and lower cover 26, has waterstop pad Figure 27 between loam cake and the lower cover.Have a kind of microporous filter tube 28 in the cleaner, this microporous filter tube adopts microporous polyethylene sintering chimney filter, and the aperture can be 5 μ, and the above solid particle of energy filtering 0.5 μ forms the material of turbidity, comprises fine organic matters such as microbial bacterial.Microporous filter tube 28 is cylindric, has an inner chamber 29, forms an exocoel 30 between it and the outer casing inner wall.At the top of loam cake 21, have mesopore 31 and lateral opening 32, mesopore 31 communicates with inner chamber 29, and lateral opening 32 communicate with exocoel 30.When above-mentioned combination valve 3, when being installed on the loam cake 21 of cleaner 2, the filter mouthfuls 11 of connecing of combination valve communicates with lateral opening 32, connects filter mouth 12 and communicates with mesopore 31.

Below in conjunction with accompanying drawing, the controlled water flow process of the combination valve of each user mode is described.

(1) system water state: with reference to Fig. 6, when twisting rotary handle 22 during to position as shown in the figure, the water inlet 7 of valve pocket is aimed in the limbers 16 of valve shaft, current are 15 exocoels 30 that enter cleaner through the limbers, see through microporous filter tube 28 and enter inner chamber 29, microporous filter tube is held back impurity, and clear water, is flowed out by delivery port 8 18 to limbers 17 through the limbers.

(2) blowdown state: valve shaft inhour on the state of Fig. 6 is revolved and is turn 90 degrees, be state shown in Figure 7, valve pocket water inlets 7 are aimed in limbers 18, current through the limbers 17 to cleaner inner chamber 29, to exocoel 30, like this, comparing with the current of above-mentioned system water state becomes " backflowing " state, and therefore, current are the anti-impurity that falls to being trapped of evading in microporous filter tube, and with current through the limbers 13 to limbers 14, discharge from sewage draining exit 10.

(3) non-filter state: valve shaft on Fig. 7 state again inhour revolve and turn 90 degrees as shown in Figure 8, water inlets 7 water inlets are aimed in the limbers 17 of valve shaft, current are directly flowed out through delivery port 9 by limbers 19 without microporous filter tube, provide the tap water without cleaner.

(4) closed condition: valve shaft on the state of Fig. 8 again inhour revolve and turn 90 degrees (as Fig. 9), any limbers misalignment water inlet 7 all on the valve shaft at this moment, clarifier quits work.

Use the utility model, when water yield occurring and descend, explanation need be removed contamination, at this moment if twisting rotary handle 22 to the blowdown position, the contamination in the cleaner (2) can be eliminated rapidly, remove contamination the time as long as the several seconds can finish.The utility model is used in the working head that has more than 10 meters, and the effect of then removing contamination is better.
