Gravity flow system, pipeline lay to fire cistern from pipe well in a basement high position and need certain gradient, occupy larger
Basement floor height, it cannot be guaranteed that the minimum clear height of basement is required when serious.
Utility model content
The technical problems to be solved in the utility model is that transverse tube lays in order to overcome standpipe caliber of the prior art excessively thick
Need the gradient, take piping shaft space and the defect such as basement space is excessive, there is provided a kind of pressure drainage system.
This utility model is solving above-mentioned technical problem by following technical proposals：
A kind of pressure drainage system, its include fire-fighting transfer water tank, downflow weir, siphon rainwater head, water leg, draining stand
Pipe, dewatering horizontal tube, low level fire cistern, the downflow weir are arranged at the top of the water leg, and the water leg is connected to institute
The internal face of fire-fighting transfer water tank is stated, the siphon rainwater head is arranged at the inner bottom of the water leg, the soil stack
Upper end be connected to the siphon rainwater head, the lower end of the soil stack is connected to one end of the dewatering horizontal tube, the row
The other end of water transverse tube is connected to the low level fire cistern.
It is preferred that the nominal diameter of the siphon rainwater head is 150 millimeters.
It is preferred that the material of the fire-fighting transfer water tank is rustless steel or steel plastic compount.
It is preferred that the base area of the water leg is 1 square metre, depth is 0.5 meter.
It is preferred that the soil stack is arranged in water pipe manhole.
It is preferred that the nominal diameter of the soil stack is 150 millimeters.
It is preferred that the dewatering horizontal tube is laid in a basement high position.
On the basis of common sense in the field is met, above-mentioned each optimum condition, can combination in any, obtain final product this utility model respectively compared with
Good example.
Positive effect of the present utility model is：
Pressure drainage system of the present utility model, effectively reduces the caliber of soil stack so that the piping shaft space of occupancy
Reduce；Meanwhile, dewatering horizontal tube does not need the gradient, reduces and takes basement space, improves space availability ratio.

Specific embodiment
Below by embodiment mode and combine accompanying drawing to become apparent from intactly illustrating this utility model, but not therefore
Among this utility model is limited in described scope of embodiments.
In description of the present utility model, it is to be understood that term " on ", D score, "front", "rear", "left", "right",
The orientation or position relationship of the instruction such as " vertical ", " level ", " top ", " bottom " " interior ", " outward " be based on orientation shown in the drawings or
Position relationship, is for only for ease of description this utility model and simplifies description, rather than indicate or imply device or the unit of indication
Part must have specific orientation, with specific azimuth configuration and operation, therefore it is not intended that to restriction of the present utility model.
As shown in figure 1, pressure drainage system of the present utility model, which includes fire-fighting transfer water tank 1, downflow weir 4, siphon
Roof drain 2, water leg 3, soil stack 5, dewatering horizontal tube 6, low level fire cistern 7, the material of fire-fighting transfer water tank 1 can be for not
Rust steel, steel plastic compount or other can be used for make assembled water tank material so that will not rust corrosion.Water leg 3 is connected to and disappears
The internal face of anti-transfer water tank 1, siphon rainwater head 2 are arranged at the inner bottom of water leg 3, and the base area of water leg 3 should be expired
The installation requirement of sufficient siphon rainwater head 2, the depth of water leg 3 should also meet bucket of the siphon rainwater head 2 when drainability is reached
The front depth of water, in combination with the assembled modulus of finished product water tank, it is preferable that the base area of water leg 3 is 1 square metre, and depth is 0.5
Rice.
As shown in Fig. 2 downflow weir 4 is arranged at the top of water leg 3, and when on downflow weir 4, edge is flushed with flood level, overflow
Overall width of the weir 4 in three directions should ensure that the water yield that overflow goes out can be flowed in water leg 3 in time, and require when spillway discharge reaches
When maximum, it is ensured that the water level depth for being higher by edge on downflow weir 4 is less than 0.1m.
In order to ensure that the water energy in water leg 3 is excluded in time, siphon rainwater head 2 should be more than or equal to from design drainability
The water yield of overflow, it is preferable that the nominal diameter of siphon rainwater head 2 is 150 millimeters, produces pressure current, energy by siphon rainwater head 2
Ensure that general drainability, all in more than 100L/s, can meet the spillway discharge of the fire-fighting transfer water tank 1 of general high-rise building；
Meanwhile, the flow at high speed that siphon rainwater head 2 is produced can play a part of to clean drainage pipeline, it is to avoid drainage pipeline deposits.
As shown in figure 1, the upper end of soil stack 5 is connected to siphon rainwater head 2, the lower end of soil stack 5 is connected to draining
One end of transverse tube 6, the other end of dewatering horizontal tube 6 are connected to low level fire cistern 7.5 bearing capacity of soil stack should meet this pressure
The operating pressure of power streaming system, while drainability should reach the spillway discharge of fire-fighting transfer water tank 1.Preferably, soil stack 5
Nominal diameter only just can meet above-mentioned requirements for 150 millimeters, and pressure streaming system causes the nominal diameter of soil stack 5 to subtract
Little, soil stack 5 is arranged in water pipe manhole, it is possible to resolve the gravity drainage system caliber of traditional fire-fighting transfer water tank overflow is excessive to be accounted for
With larger piping shaft space.
Dewatering horizontal tube 6 is laid in a basement high position, and its bearing capacity should meet the operating pressure of this pressure streaming system, due to
System is pressure current, therefore which can be not required to arrange the gradient with horizontal laying, and the final overflow water yield is thrown in low level fire cistern 7.
Greatly reduce dewatering horizontal tube 6 and take basement space, improve space availability ratio.
Although the foregoing describing specific embodiment of the present utility model, it will be appreciated by those of skill in the art that
This is merely illustrative of, and protection domain of the present utility model is defined by the appended claims.Those skilled in the art
On the premise of without departing substantially from principle of the present utility model and essence, various changes or modifications can be made to these embodiments,
But these changes and modification each fall within protection domain of the present utility model.
