The frictional resistance of ball room.
The utility model has the advantages that a kind of initial rainwater shunt rainwater down pipe of the utility model, has the advantages that
(1) the rainwater down pipe upper section vertical portion in the utility model is connected with roof drainage pipe, and at rainfall initial stage, pollutant is dense
It spends higher initial rainwater and enters rain water drainage pipe through a section dirty pipe, the rainwater in rain water drainage pipe is introduced by municipal administration by sewage pipe
Sewage network or the recharge groundwater after surface soil filtering, absorption, ion exchange, precipitating and biochemical action.With rainfall
Continue, when amount of rainfall be more than abandoned stream tube capacity product when, floating ball under the action of rainwater buoyancy by drive rod promotion closed shutter,
Middle and later periods rainwater is discharged into municipal Storm Sewer Network by rainwater down pipe lower section vertical portion or enters water tank.The utility model utilizes
The gravity of the buoyancy of rainwater and floating ball, drive rod, gate itself in rain water drainage pipe, after dexterously realizing initial rainwater in
The separation of phase rainwater shunts, and application prospect is very wide.
(2) rainwater down pipe is connected with dirty manage is cut by square knuckle in the utility model, and square knuckle is adapted to fit gate fortune
Capable slideway, while gate can be made tight shut-off, be conducive to initial rainwater and middle and later periods rainwater is completely separable, improve in after
The water quality of phase rainwater.
(3) rain water drainage pipe is made of more piece straight tube with bend pipe in the utility model, reduces the height of rain water drainage pipe,
Convenient for being installed on outdoor buildings wall.

Specific embodiment
The utility model is further described with reference to the accompanying drawing.
As shown in Figure 1 to Figure 2, a kind of initial rainwater shunt rainwater down pipe of the utility model, including rainwater down pipe 1, section dirt
Pipe 2, sewage pipe 3, rain water drainage pipe 4, float chamber 5, floating ball 51, drive rod 52, gate 6, slideway 7 and square knuckle 8.Rainwater down pipe
1 is connected with roof drainage pipe, and rainwater down pipe 1 is made of upper section vertical portion, middle section horizontal component and lower section vertical portion, and rain is fallen
The mid-horizontal section of pipe 1 is connected with section dirty 2 one end of pipe by square knuckle 8, and dirty 2 other end of pipe and rain water drainage pipe 4 are cut
It is connected.Rain water drainage pipe 4 is made of more piece straight tube with bend pipe, and 4 the lowermost straight tube of rain water drainage pipe is connected with sewage pipe 3
Logical, 4 upper end of rain water drainage pipe is connected with float chamber 5.Floating ball 51 is located in float chamber 5, and the shape of float chamber 5 is cylindrical body,
5 internal diameter of float chamber is slightly larger than the diameter of floating ball 51.Floating ball 51 and the contact surface of float chamber 5 are equipped with no outer ring ball bearing.Floating ball 51
It is connected by drive rod 52 with gate 6, slideway 7 is equipped in square knuckle 8, gate 6 is mounted in slideway 7.Among square knuckle 8
