According to Fig. 1-shown in Figure 3, the utility model mainly comprises: rain-water drainage mouth 1, grit chamber 2, anti-foul smell inlet 3, U-lag 4, deodorization air valve 5, outlet 6, A-A line the 7, the 1 degree elbow the 8, the 2 90 degree elbow 8 ', surface of the street 9, fixedly rubber cushion 10, stop valve cut down sheet 11, U-shaped pipe 12, hinge 13.

The one 90 degree elbow the 8, the 2 90 degree elbow 8 ' the lower end fixedly connected with the two ends of U-shaped pipe 12 by anti-foul smell inlet 3, deodorization air valve 5 respectively; Be provided with the stop valve that multi-disc can open, close about deodorization air valve 5 and cut down sheet 11; Stop valve cuts down sheet 11 and flexibly connects by hinge 13 and U-shaped pipe 12.

The upper end of the one 90 degree elbow 8 fixedly is communicated with the top of grit chamber 2; The 2 90 the degree elbow 8 ' the upper end be provided with the outlet 6.

U-shaped pipe 12 comprises: anti-foul smell inlet 3, deodorization air valve 5; U-shaped pipe 12 is provided with U-lag 4; A-A line 7 is tangent with the minimum point of U-lag 4 upper base turn of bilges; The position of cutting down sheet 11 contact surfaces with stop valve on the U-shaped pipe 12 is provided with fixedly rubber cushion 10.

Operating principle: the U-shaped deodorant is to form with curved transformation of the diving between blowdown is connected according to the washroom bedpan that is widely used in esidential building; At present the diving that uses is curved is to rely on being stored in the foul smell that the water of diving in curved intercepts in the blow-off pipe and scurrying outward.When the washroom did not use for a long time, after the water in diving is curved was evaporated, owing to there is not the obstruct of water, the foul smell in the blow-off pipe was just scurried outward, does not have the effect of long-term deodorization.And the U-shaped deodorant is improved at the curved weakness of diving just and is formed; Promptly in the U-bend outlet stop valve is installed, when water flowed, stop valve was opened, and when current stopped, stop valve was closed, and the foul smell that intercepts in the blow-off pipe is scurried outward, plays the effect of deodorization.

At present, the rain-water drainage well head of avenue, road both sides is directly to communicate with the urban sewage ditch, although street, road are clean and tidy, clean, also often smells one foul smell, no matter you walk on that street, city, as long as just the row's of walking close to rainwater well head can smell fitful stench.This stench, not only the healthy of both sides, street resident lived in influence for a long time, returns the pedestrian and smells one [frequently and feel sick, and both influenced the health in city, influences townsfolk's life and the life-span again; After the U-shaped deodorant is installed, urban air will be more pure and fresh, and the resident lives more comfortable, and quality of life will be higher.Owing to there is not the invasion of foul smell, resident's disease reduces, and is more healthy, more long-lived.To resident, all very beneficial to society; Particularly people's quality of life today of improving constantly, the U-shaped deodorant is installed is more seemed very necessary.

At first, the curved just little bend pipe of diving, moisture storage capacity is few, and the critical point of obstruct foul smell is very low, is at a slight tilt owing to installing sometimes, does not just have the effect of deodorization.And the U-shaped deodorant has adopted the U-shaped design, will save water to greatest extent, and the critical point that intercepts foul smell is higher, under water-filled situation, and can be below the subcritical point in one month.Secondly,, a stop valve is installed,, is played the effect that the obstruct foul smell is scurried outward, thereby reach the effect of long-term deodorization when water level in the U-shaped pipe is reduced to critical point when following in U-shaped pipe exit.

The U-shaped deodorant mainly adopts: utilize the water resistance foul smell in the blowdown ditch that stores in the U-shaped pipe to scurry outward; Utilizing U-shaped pipe 12 interior installation stop valves to intercept the interior foul smell of blowdown ditch scurries outward.Stop valve is made up of two semi-circular sheets that cut down, form by hinge is fixed on the U type tube wall mouth, when impact of water, cutting down sheet opens, water just cuts down between sheet from two and spills out, and when current stop, cutting down sheet and close (closing) down under the deadweight effect, foul smell can't be scurried outward, play the effect that prevents that for a long time foul smell from scurrying outward.

When rainy day, the rainwater on the street is in rain-water drainage mouth 1 flows into grit chamber 2, and behind the deposition sand grains, rainwater flows in the U-lags 4 from anti-foul smell inlet 3, wash deodorization air valve 5 then open after, through exporting 6 tube connectors, flow into then in the blowdown ditch.

In the process of current, owing to be full of rainwater in the U-lag 4 of U-shaped deodorant, the foul smell of blowdown ditch can't be scurried outward, and the water in the U-lag 4 has played the effect that foul smell is scurried that intercepts outward.

When current stop, deodorization air valve 5 under the effect of self gravitation, close and U-lag 4 in the water foul smell that intercepts the blowdown ditch together scurry outward.

When the water level in the U-lag 4 was lower than A-A line 7, deodorization air valve 5 was in closed condition, and the effect that foul smell is scurried that intercepts has been played on the road surface of also can't scurrying out of the foul smell in the blowdown ditch outward.

U-lag 4 is designed to a semi-circular shape, and purpose is in order to accelerate the water velocity in the U-lag 4, as far as possible the deposit that is deposited in the U-lag 4 to be washed away.

Process: U-shaped pipe 12 adopts the production technology of mould, carries out mould according to the inside and outside caliber of U-shaped pipe 12 earlier, just can put into production in enormous quantities.

Production procedure: sheet → inspection sealing situation → dispatch from the factory is cut down in processing mold → moulding → perfusion → pressing mold → cooling → form removal → installation.
