Abstract
The utility model discloses a kind of special single-stack drain system cyclone pipe fitting, the swirl-vanes comprising standpipe, horizontal arm and be arranged on standpipe inwall, also comprise embedded mozzle, described embedded mozzle embeds inside described standpipe, and the bottom of embedded mozzle extends to horizontal arm nozzle position; The outer wall of described embedded mozzle arranges moisture film shedding motion; The utility model has the advantages that: it is descending smoothly that rotary water current descending for upper strata is avoided horizontal arm by " embedded mozzle " design, prevent top standpipe from rotating descending current because centrifugal force is by " get rid of into " horizontal arm, near and the air pressure fluctuation eliminated in standpipe and the generation reducing draining noise." moisture film " can be opened at horizontal branch pipe interface place by " moisture film shedding motion " design, make the air duct between horizontal arm and standpipe keep unimpeded, ensure that air pressure relative equilibrium, eliminate the fluctuation of pipeline internal gas pressure, realize steadily and not destroying of cleaning device water seal, thus realize free from extraneous odour.
Description
Technical field
The utility model relates to drainage plant field, is a kind of gutter specifically.
Background technology
The architectural drainage system of tradition building, is made up of two bye-passes, is respectively used to water flowing and ventilation, takies the construction cost of living space, waste constructional materials, increase, the shortcomings such as drainage noise is large, installation and maintenance amount is large.Special single-stack drain system (as shown in Figure 2) technique functions comes from Europe, in American-European and Japanese development and application four more than ten years nearly, special single standpipe constantly carries out technological improvement in use procedure for many years, drainage performance have also been obtained and significantly promotes, be widely used in the places such as high-rise residential building, hotel, hospital, receive the popular welcome in market.
Special single standpipe is according to flow characteristics, in inside pipe fitting design, there is the swirl-vanes device of changing the direction of a stream of water, when the sewage that sanitary apparatus is discharged enters into standpipe through horizontal arm, sewage is through the effect of special single standpipe swirler, the sewage entered in standpipe is made to form swirling flow, allowing sewage be close to standpipe tube wall rotates descending, and then makes to form hollow air discharge in the middle of standpipe, eliminates the air pressure in soil stack.
But there is following problem in special single standpipe: it is descending smoothly that the descending rotary water current in special single standpipe upper strata cannot avoid horizontal arm, top standpipe rotates descending current because centrifugal force is by " get rid of into " horizontal arm, produce " adverse current " phenomenon, as the adverse current 7 in Fig. 2, simultaneously top standpipe rotates descending current and horizontal arm current collide, thus create " overflow " phenomenon, and then cause the generation of air pressure fluctuation in standpipe and draining noise.
In addition, when rotating descending current in standpipe, when flow is larger, riser interiors can an of short duration formation hollow water column both " moisture film ", horizontal arm and standpipe air are produced isolate, cause gas in standpipe and horizontal arm to produce pressure differential phenomenon, closely destroy the water seal of cleaning device, pernicious gas is flowed into indoor.
Utility model content
For solving the problems of the technologies described above, the purpose of this utility model is to provide special single-stack drain system cyclone pipe fitting, and can effectively solve the problems of the technologies described above, concrete technical scheme is as follows:
A kind of special single-stack drain system cyclone pipe fitting, the swirl-vanes comprising standpipe, horizontal arm and be arranged on standpipe inwall, it is characterized in that: also comprise embedded mozzle, described embedded mozzle embeds inside described standpipe, and the bottom of embedded mozzle extends to horizontal arm nozzle position.
The outer wall of described embedded mozzle arranges moisture film shedding motion.
The bottom of described embedded mozzle extends to 0.3-0.5 doubly horizontal arm nozzle diameter place.
The projection of described moisture film shedding motion to be top be thorn-like.
Described projection is rectangular pyramid.
Described projection is many needle-likes.
The utility model has the advantages that: it is descending smoothly that rotary water current descending for upper strata is avoided horizontal arm by " embedded mozzle " design, prevent top standpipe from rotating descending current because centrifugal force is by " get rid of into " horizontal arm, produce " adverse current " phenomenon, also top standpipe is avoided to rotate descending current and horizontal arm current collide, thus avoid the generation of " overflow " phenomenon, closely eliminate the air pressure fluctuation in standpipe and the generation reducing draining noise.
" moisture film shedding motion " designs.Domestic existing special single standpipe design principle is all theoretical according to " film stream ".When rotating descending current in standpipe, when flow is larger, riser interiors can an of short duration formation hollow water column both " moisture film ", horizontal arm and standpipe air are produced isolate, gas in standpipe and horizontal arm is caused to produce pressure differential phenomenon, closely destroy the water seal of cleaning device, pernicious gas is flowed into indoor.In order to avoid this phenomenon, " moisture film " can be opened at horizontal branch pipe interface place by exclusive " moisture film shedding motion " design, the air duct between horizontal arm and standpipe is made to keep unimpeded, ensure that air pressure relative equilibrium, eliminate the fluctuation of pipeline internal gas pressure, realize steadily and not destroying of cleaning device water seal, thus realize free from extraneous odour.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is prior art structural representation;
In figure, 1 is standpipe, and 2 is horizontal arm, and 3 is embedded mozzle, and 4 is moisture film shedding motion, and 5 is swirl-vanes, and 6 is current, and 7 is adverse current.
Detailed description of the invention
The utility model is illustrated below in conjunction with accompanying drawing, as shown in Figure 1, the swirl-vanes 5 that the utility model comprises standpipe 1, horizontal arm 2 and is arranged on standpipe inwall, also comprise embedded mozzle 3, described embedded mozzle 3 embeds inside described standpipe 1, and the bottom of embedded mozzle 3 extends to horizontal arm 2 nozzle position; The outer wall of described embedded mozzle 3 arranges moisture film shedding motion 4; Described moisture film shedding motion 4 for top be the projection of thorn-like.
The bottom of described embedded mozzle 3 extends to 0.3-0.5 doubly horizontal arm 2 nozzle diameter place.
Described projection is rectangular pyramid; Can also be other shapes, as long as can be used in puncturing " moisture film ", as arranged many needle-like moisture film shedding motions etc.
