Description
Technical field
The present invention relates to architectural drainage system field, a kind of particularly energy dissipating muffler for drainage system.
Background technology
At present, architectural drainage system is very common using UPVC plastic tubes, but, for cast iron pipe, plastic tube is deposited
In the shortcoming that intensity is not enough, noise is of a relatively high, when being especially applicable to skyscraper, due to plastic conduit inner wall smooth, rub
Wipe power small, streaming potential is big, make flow rate of water flow in standpipe big, to the intensity of pipeline, the stability shadow of sealing and drainage system
Ring larger, the elbow of destructible riser bottom when there are hard debris to fall with current.In order to reduce vertical in-pipe flow stream
Speed, reduces influence of the streaming potential to pipeline, and general every 6 layers of skyscraper sets an energy dissipator, in the market not
There is the accessory dedicated for energy dissipating, generally using the simple energy dissipating dress being assembled into by 4 one eighth bends and 1 vertical tube inspection hole
Put, as shown in Figure 1.
Although this simple energy dissipator can effectively reduce standpipe water velocity, negative-pressure ward phenomenon in standpipe is reduced, protected
Shield riser bottom elbow, but have the shortcomings that quite serious, i.e. energy dissipator local resistance is excessive, impeded drainage occurs, sternly
Ghost image rings standpipe water passing capacity, when design safety factor (DSF) does not have sufficiently high, and concentration is compared in standpipe draining, closes on energy dissipator
Last layer toilet has sewage outflow situation to occur.
Just because of this easy assembly has serious deficiency, at present, national regulation is asked for skyscraper energy dissipating
Topic does not have specific corresponding to measure, only some provincial standards.For high-rise draining in Practical Project, in order to reduce current
Potential energy makes the influence of twin conduit, general podium and uses cast iron pipe with lower portion, standpipe and horizontal main, with upper bit using moulding
Expects pipe, more than podium every 6 layers set one group of energy dissipator.For high-rise draining in Practical Project, typically all one is set using every 6 layers
Group energy dissipator, podium and uses cast iron pipe with lower portion standpipe and horizontal main, and other positions use plastic tube, when using energy dissipating
Design safety factor (DSF) will be typically increased during device, so allowing for drain pipe system can not give full play to due draining energy
Power.
