Description
Technical field
The utility model relates to a kind of siphonic drainage system, the siphonic drainage system on especially a kind of roofing.
Background technology
On present roofing, the drainage pattern of rainwater is mainly divided into two kinds: one is Conventional gravity formula storm-water system, its principle is the gradient utilizing roof structure, that in the roof drain that naturally flows on roofing of rainwater, the effect that then rain water and air is mixed together by gravity is descended along standpipe; This mode drainage efficiency is low, needs number of tubes many, and the caliber of pipeline is comparatively large, and needs the gradient of 1%-3%, installs also complicated.Another kind is exactly siphon type rainwater discharging system, at the initial stage of rainfall, when on roofing, the rainwater degree of depth is more shallow, rainwater still utilizes the principle of gravity to carry out draining, after amount of precipitation strengthens, when the water level on roofing reaches certain height, roof drain can cut off air automatically automatically, thus generation siphon, drainage system just changes efficient exhaust system into, and suction rainwater discharges downwards.Although the efficiency of siphonic drainage system force of gravity formula drainage system wants high a lot, but siphon drainge system also comes with some shortcomings now: the height of the building had is too high, the potential energy of the position the closer to ground in standpipe is larger, cause on the one hand the overbottom pressure of stand-pipe output and flow velocity bigger than normal, larger to the impulse ratio of building foundation, drainage system negative pressure can be caused to exceed standard on the other hand, not meet the design discipline of siphonic drainage system; May make shorten the application life of standpipe so for a long time, and in a lot of highly very high and baroque building, the difficulty of replacing standpipe is very large; Two, the air being still entrained with fraction in rainwater enters into roof drain, first the efficiency of draining is reduction of, and the pressure of negative pressuren zone can be made in the negative pressuren zone in air arrival system to increase, cause the pumping function of negative pressuren zone to rainwater bad, affect the drainage efficiency of whole system; Three, the silt in rainwater can flow in the hanging pipe of level by roof drain, and for a long time, silt can deposit in hanging pipe, hanging pipe is blocked, once there is above situation, the very difficult cleaning of the silt in hanging pipe, changes hanging pipe also very difficult.
Utility model content
For the problems referred to above of the prior art, the utility model proposes a kind of Siphoning type roof drainage system, the overbottom pressure and the flow velocity that solve system neutral tube delivery port are bigger than normal, can cause larger impact, also affect the application life of standpipe to building lot; Air can enter into roof drain, the technical problem of the drainage efficiency of influential system.
The technical solution of the utility model is: Siphoning type roof drainage system, comprises several roof drains, hanging pipe and standpipe, and several roof drains described are communicated with the hanging pipe of level respectively by adapter, and the water side of described hanging pipe is connected with the water inlet end of standpipe; The inwall of the middle and lower part of described standpipe is provided with from top to bottom successively the first buffer board of cirque structure, the second buffer board, the 3rd buffer board, the internal radius of described first buffer board, the second buffer board, the 3rd buffer board reduces successively; The delivery port of described standpipe is horn-like structure.
Further, described roof drain end face is provided with the radome fairing preventing air from entering roof drain.
Further, baffle plate is provided with immediately below described delivery port.
Further, two ends, described baffle plate left and right are fixedly connected with the two ends, left and right of delivery port respectively by two pull bars.
Further, immediately below described roof drain, riffler is installed.
Compared with prior art, the beneficial effects of the utility model are:
1. the utility model is provided with the first buffer board, the second buffer board, the 3rd buffer board successively by the middle and lower part of the standpipe in drainage system, the buffer board internal diameter of three circular ring structures reduces successively, can the pressure of minimizing stand-pipe output end progressively and the flow velocity of rainwater, the middle and lower part of standpipe can not be made to be in the environment of larger pressure for a long time, and can effectively prevent current faster from causing very large impact to building lot, prevent from impacting for a long time, can impact the steadiness of building lot, long-term hidden danger is existed to building; And the negative regulation of negative pressuren zone can be kept, there will not be the situation that negative pressure exceeds standard.
2. the port of export of the utility model standpipe is arranged in horn-like, and effectively reduce the flow velocity of rainwater, immediately below the port of export, be connected with baffle plate, baffle plate makes rainwater can not cause direct impact to building lot, carries out dual protection to building lot.
3. the top of roof drain of the present utility model is provided with the radome fairing preventing eddy current, prevent air from together flowing in roof drain along with rainwater exactly, reduce the drainage efficiency of system, and prevent air from flowing in negative pressuren zone, air can increase the air pressure of negative pressuren zone, make the suction effect of negative pressuren zone to the rainwater on roofing bad, prevent the drainage efficiency affecting whole system.
4. the below at roof drain in the utility model is provided with riffler, prevents the silt in rainwater from being flow in hanging pipe by roof drain and adapter and precipitates, effectively prevent hanging pipe to be blocked by silt, increases the service time of whole system.
