Abstract
The utility model discloses a ventilative vertical water draining pipe composed of a straight pipe and a pipe fitting, wherein the straight pipe and the pipe fitting are composed of an inner pipe, an outer pipe and a supporting board, the inner pipe is sheathed in the outer pipe, and the inner pipe and the outer pipe are connected by the supporting board. Due to the adoption of the sleeve pipe structure that the inner and the outer two pipes are sheathed, the ventilative vertical water draining pipe of the utility model uses a gap between the inner and the outer pipes as a ventilating passage which integrates water drain and ventilation together, therefore, the utility model dispenses with a special-purpose ventilating pipeline and saves construction space; the pressure fluctuation in a vertical pipe is reduced so that the water seal of the utility model is not easy to destroy, and meanwhile, the utility model effectively prevents water leakage and reduces water flowing noise.
Description
The utility model relates to a kind of soil stack of many, high-rise building drainage system, particularly relates to a kind of aeration type soil stack.
At present, in order to prevent owing to the pressure oscillation in the soil stack makes that the utensil drain water seal that communicates with it is destroyed, the foul smell escape is in building, highrise building is laid gutter and ventilating pipe mostly simultaneously when laying drainage pipe, owing to need to lay gutter and ventilating pipe two tubes simultaneously, it is big to take building area, and expense is bigger, and construction is inconvenient.Ventilating pipe can be divided into no ventilating pipe usually, stretch top formula ventilating pipe, special-purpose ventilating pipe, utensil ventilating pipe etc. from rudimentary to senior, multistory building adopts mostly stretches top formula ventilating pipe, but this ventilating pipe ventilation capacity is poor, and the utensil water seal is destroyed easily, and particularly the water seal of bottom is easier to be destroyed.
The purpose of this utility model provides that a kind of ventilation capacity is good, the gutter pressure oscillation is little, water seal be difficult for destroyed, aeration type soil stack little, easy construction takes up room.
In order to achieve the above object, the utility model aeration type soil stack is made up of straight tube and pipe fitting, described straight tube and pipe fitting are made up of interior pipe, outer tube and gripper shoe, interior pipe box is connected in the outer tube, interior pipe is to be connected by gripper shoe with outer tube, forms an annular space that is used to ventilate between interior pipe and outer tube; Pipe fitting is installed between straight tube, between the interior pipe of the interior pipe of interface and straight tube a gap is arranged vertically about the pipe fitting.
Because the sleeve structure that the utility model aeration type soil stack adopts inside and outside two pipe boxes to connect, utilize space between the inner and outer pipes as venting channels, make it integrate draining and ventilate, thereby defaulted special-purpose air duct, save architectural space; The pipe fitting gap of the interior pipe of interface up and down can effectively reduce the interior pressure oscillation of standpipe, and it is destroyed that the utensil water seal is difficult for; Simultaneously effectively prevented to leak, reduced the current noise
Below in conjunction with accompanying drawing and specific embodiment the utility model aeration type soil stack is further described.
Fig. 1 is the utility model aeration type soil stack structural representation;
Fig. 2 is the utility model aeration type soil stack cross-sectional view;
Fig. 3 is the utility model aeration type soil stack pipe fitting down stream tee joint scheme of installation;
Fig. 4 is the utility model aeration type soil stack pipe fitting four-way scheme of installation downstream.
As shown in Figure 1 and Figure 2, the utility model aeration type gutter is made up of straight tube 1 and pipe fitting 2.Described straight tube 1 is made up of interior pipe 11, outer tube 12 and gripper shoe 13, and interior pipe 11 is socketed in the outer tube 12, and interior pipe 11 is to be connected by gripper shoe 13 with outer tube 12, forms an annular space that is used to ventilate 14 between interior pipe 11 and outer tube 12.Be installed in pipe fitting 2 between each floor straight tube 1 and be generally down stream tee joint or four-way downstream, the interior pipe 21 of pipe fitting interface about in the of 2 respectively has a gap 3 vertically with the interior pipe 11 of straight tube 1.Outer tube 12 is 1.3-1.4 with the diameter ratio of interior pipe 11.Described gripper shoe is 3, is evenly distributed between interior pipe 11 and the outer tube 12.
Pipe fitting 2 at the foot (being the part of ground below 4) of the utility model aeration type gutter is a bend pipe 5, these bend pipe 5 upper ends are connected with straight tube 1, this bend pipe 5 is made up of pipe 51 in crooked and crooked outer tube 52, pipe 51 is socketed in the crooked outer tube 52 in crooked, pipe 51 is to be connected by bend pipe gripper shoe (not shown) with crooked outer tube 52 in crooked, and it is corresponding with the crooked radian of crooked outer tube 52 to manage 51 crooked radian in crooked.
As shown in Figure 3, pipe fitting 2 is a down stream tee joint, and this down stream tee joint is installed in 1 of straight tube, and the gap that down stream tee joint is installed on the outer tube 12 adopts cushion rubber 6 and bellmouth 7 sealings.
As shown in Figure 4, pipe fitting 2 is a four-way downstream, this downstream four-way be installed in 1 of straight tube, installing downstream on the outer tube 12, the gap of four-way adopts cushion rubber 6 and bellmouth 7 sealings.
Principle of the present utility model: the interior pipe 11 of straight tube 1 is a gutter, in between pipe 11 and the outer tube 12 formed annular space 14 be used as venting channels, pipe fitting 2 (down stream tee joint, four-way, bend pipe 5) downstream up and down in interior pipe 21 and the straight tube 1 of interface the gap 3 of pipe 11 gas circulation is flowed.Since down stream tee joint or downstream the pipe fitting 2 that constitutes of four-way have the function of blender concurrently; can reduce water bolt in the interior pipe 11 of straight tube 1 to the swabbing action on its top with to the contention effect of its underpart; and then the pressure oscillation in the pipe 11 in reducing, reach the purpose of protecting water seal.The pipe fitting 2 that the bottom is made of bend pipe 5 has the function of deflation device and releasing tube, can effectively reduce and choke water, and the water seal of protection bottom is not destroyed.
