Abstract

The utility model provides a joint for a vertical drainage pipe, consisting of an upper joint (1), a vertical pipe (2), a conical pipe (3), a lower joint (4), a transverse supporting pipe joint (5), a drainage baffle pipe (6) and a swirling flow guide plate (7). The intersection choke phenomenon of water flow in a vertical pipe and a transverse supporting pipe can be lightened so that the water flow forms swirling flow and flows downwards helically close to the pipe wall, so as to enable the middle part in a pipeline to keep smooth airflow, so that the water jamming phenomenon can be effectively prevented in the pipeline, the drainage capability of the vertical pipe in a sewer can be effectively improved, and the drainage noise can be reduced.

Description

The soil stack joint

Technical field

The utility model relates to the sewer pipeline of building union.It is the union of sewer pipe soil stack and arm.

Background technology

Building sewer gutter has single vertical pipe type and two vertical pipe type, the water gutter is to be realized by a standpipe under single vertical pipe type, and the water gutter is to be realized by two pipelines under two vertical pipe types, and one thicker is used for draining, another root is thinner is used for exhaust, and soil stack is connected with horizontal arm.Generally use two vertical pipe type gutters, but increased cost and maintenance at the high-rise building more than 10 layers.No matter be single vertical pipe type or two vertical pipe type sewer soil stack, when horizontal arm sewage flowed into standpipe, the sewage that falls with the standpipe high speed directly bumped against, and can make the interior instantaneous pressure of pipeline unbalance, made the drainage fixture damage of water block, occurred ' anti-smelly '.Simultaneously collide unordered mobilely mutually, make draining sound very big, cause the singing of the stream of ' rustlingly rustlingly ' because of horizontal arm sewage and standpipe sewage.The more important thing is instantly when current are big in the water standpipe, be easy to generate water plug phenomenon, produce positive pressuring spraying base top, water plug bottom negative pressure swabbing in the soil stack, cause the drainage fixture damage of water block, produce serious ' anti-smelly ' phenomenon.

The utility model content

The purpose of this utility model is at above-mentioned prior art problems, provides a kind of draining smooth, and noise is little, and the sewer pipeline of building soil stack joint that prevents that ' anti-smelly ' phenomenon from taking place is arranged.

The utility model soil stack joint is by top connection 1, standpipe 2, Taper Pipe 3, lower contact 4, horizontal branch pipe connection 5, drainage retaining pipe 6, eddy flow guide strip 7 constitutes, top connection 1 is connected with standpipe 2 upper port one, the upper end of drainage retaining pipe 6 is fixedly connected on standpipe 2 upper port, the upper end that is drainage retaining pipe 6 is connected with standpipe 2 upper port one, extend downwards, at least one horizontal branch pipe connection 5 is connected with standpipe 2 sides, be provided with gathering sill 50 at the interface downside, the upper end of Taper Pipe 3 is connected with the lower end one of standpipe 2, lower contact 4 is connected with the lower port one of Taper Pipe 3, it is fixedly connected a plurality of to distribute on Taper Pipe 3 inwall anchor rings, be generally 2-4 eddy flow guide strip 7, be swash plate or flight, flow downward so that current are formed rotation by this plate guiding when flowing downward.

The utility model standpipe 2 diameters are greater than sewer gutter diameter, be that standpipe 2 diameters are greater than top connection 1 bore, can produce slow unhurried current effect to the sewage that top flows down, 6 pairs of descending sewage of drainage retaining pipe play the current stabilization effect, alleviate simultaneously the liquidate choked flow phenomenon of standpipe current greatly to horizontal arm current, can prevent that also horizontal arm from forming overflow blocking-up air-flow phenomenon in standpipe, effectively reduce the pressure oscillation in the drainage system, the current that drainage retaining pipe 6 imports standpipe current and horizontal arm stream form eddy flow fast, and, make current form eddy flow under eddy flow guide strip 7 effects that sewage is distributing on the Taper Pipe 3 inwall anchor rings under drainage retaining pipe 6 guiding cooperate, it is descending to be close to the tube wall rotation, and the G﹠W in the pipeline is effectively separated, and makes maintenance hollow in middle part in the pipeline, air-flow is unobstructed, have to prevent that the water plug takes place in the pipeline, destroy the drainage fixture water seal, produce ' anti-smelly ' phenomenon, effectively improve sewer standpipe drainability, and reduce draining noise.

The specific embodiment

The utility model soil stack joint is by top connection 1, standpipe 2, Taper Pipe 3, lower contact 4, horizontal branch pipe connection 5, drainage retaining pipe 6, eddy flow guide strip 7 constitutes, top connection 1 is connected with standpipe 2 upper port one, the upper end of drainage retaining pipe 6 is connected with standpipe 2 upper port one, the below is stretched in the lower end of drainage retaining pipe 6, at least one horizontal branch pipe connection 5 is connected with standpipe 2 sides, be provided with gathering sill 50 at the interface downside, so that entering the current of standpipe, horizontal arm better flows into downwards along tube wall, reduce influence to descending current in the standpipe, the upper end of Taper Pipe 3 is connected with the lower end one of standpipe 2, lower contact 4 is connected with the lower port one of Taper Pipe 3, and fixedly connected 2-3 the eddy flow guide strip 7 that be provided with distributes on Taper Pipe 3 inwall anchor rings.
