Background technology
Cyclone is one of special single-stack drain system novel special accessory, using single standpipe draining of cyclone
System, it is big to have flow compared with the special single riser systems of other, the advantages of take up room little.Shown in Figure 1, existing rotation
Stream device 10 top standpipe interface is generally centrally disposed cylindrical short pipe 11, and the lower body rotary fluid 12 of cyclone 10 is provided with
Multiple helical blades 13, there is following defect in the cyclone 10 of this structure: 1, when for high level and high-rise building, big row
Amount draining when, due to top standpipe interface in centre so as to mass-flow down, just colliding multiple in lower body rotary fluid 12
On helical blade 13, as shown in Fig. 2 producing larger amplitude beat and noise；2nd, because helical blade 13 quantity is excessive, produce
Multi-strand flow, exacerbates soil stack run-off the straight swing and beat vibration again, changes the helical flow of water shape in pipeline
State so as to drainability has declined, the shortcoming that generally existing flow rate of water flow is very fast and effect of energy dissipation is poor；3rd, existing cyclone
The cylindrical short pipe 11 on 10 tops standpipe interface central authorities is long, and the foam group flowing through the current formation of horizontal arm 14 can make in pipeline
The density of gas increases, and have impact on the speed that air-flow is discharged upwards, and so that the pressure oscillation in pipeline is aggravated, and particularly flows big
Under amount state, this phenomenon is especially apparent, and reduces pressure stability during drainage system draining.When displacement increases, stand
Larger pressure oscillation and vibration noise is produced in pipe.Above-mentioned problem, exactly current Chinese patent Authorization Notice No.
A kind of modified polypropene quiet cyclone list standpipe draining disclosed in cn202416476u (authorized announcement date is 2012.09.05)
Plumbing problem encountered.
Content of the invention
