Description
Technical field
The utility model is related to construction drainage field, and in particular to a kind of siphon drainge system for building.
Background technology
The drainage pattern of rainwater is broadly divided into two kinds on present roofing：One kind is Conventional gravity formula storm-water system, its
Principle is the gradient using roof structure, is that rainwater is flowed into the roof drain on roofing naturally, then rain water and air is mixed together
Close by gravity effect along standpipe and under；This mode drainage efficiency is low, it is necessary to number of tubes is more, the caliber of pipeline compared with
Greatly, and need the 1%-3% gradient, install complicated.Another is exactly siphon type rainwater discharging system, at the initial stage of rainfall,
When rainwater depth is shallower on roofing, rainwater still carries out draining, after rainfall is increased, the water on roofing using the principle of gravity
When position reaches certain height, roof drain can separate air automatically, so as to produce siphon, drainage system is just changed into efficient row
Place system, suction rainwater is discharged downwards.Although the efficiency of siphonic drainage system force of gravity formula drainage system is much higher,
Present siphon drainge system still has several drawbacks：The height of some buildings is too high, in standpipe closer to ground position gesture
Can be bigger, on the one hand cause the overbottom pressure and flow velocity of stand-pipe output bigger than normal, it is larger to the impulse ratio of building foundation, on the other hand it can make
It is exceeded into drainage system negative pressure, it is unsatisfactory for the design discipline of siphonic drainage system；It may so cause the use of standpipe for a long time
The lost of life, and in many very high and baroque buildings of height, the difficulty for changing standpipe is very big；2nd, in rainwater also
It is to be entered entrainment of the air of fraction in roof drain, is reduction of first in the efficiency of draining, and air arrival system
Negative pressuren zone in the pressure of negative pressuren zone can be caused to increase, cause negative pressuren zone bad to the pumping function of rainwater, influence whole system
Drainage efficiency；3rd, the silt in rainwater can be flow into horizontal column pipe by roof drain, for a long time, and silt can be
Deposited in column pipe, column pipe is blocked, once occur the very difficult cleaning of silt in case above, column pipe,
Change column pipe also highly difficult.
Utility model content
The utility model purpose is to provide a kind of siphon drainge system for building, solution system neutral tube
