Abstract
The utility model relates to a swirling-flow noise-reduction joint for a building drainage stand pipe, which comprises a joint main body composed of a capacity expansion connector and a swirling-flow cone body, wherein as for the capacity expansion connector, a main stand pipe interface is formed at the upper part, a swirling-flow cone interface is formed at the bottom, and a horizontal branch pipe interface, which is connected with the capacity expansion connector through a stream guidance water channel, is formed on the side surface; the main stand pipe interface is integrally arranged in the capacity expansion connector; the outer diameter of the capacity expansion connector is larger than that of the main stand pipe interface; and as for the swirling-flow cone body which is cone-shaped, the capacity expansion connector interface is formed at the upper part, a swirling-flow blade is arranged on the inner wall, and the main stand pipe interface is formed at the bottom. The joint provided by the utility model has the advantages that the water flow in the main stand pipe is clung to the inner wall of the pipe and flows downwards in a swirling state so as to naturally form a clear air way in the center, and meanwhile, the influence of the horizontal branch pipe water flow on the main stand pipe water flow is avoided, the drainage noise is lowered and the drainage capacity is improved.
Description
Technical field
The utility model relates to a kind of construction drainage pipe fittings, particularly a kind of construction drainage standpipe swirling-flow noise-reduction joint.
Background technique
At present, often use UPVC drainage pipe and pipe fitting in the construction drainage riser systems, and UPVC waste pipe inner wall smooth, current are difficult to form effective moisture film structure, when therefore the UPVC waste pipe is as the standpipe draining, the current that fall in the pipeline present chaotic state, current constantly with tube wall, with the air of partial closure, produce bump formation noise with the drop that splashes etc., and UPVC waste pipe wall thickness is thinner, the density of material own is not high, iris action to noise is little, and the noise that spreads out of from drainage conduit body has affected people's quality of life greatly.The various types of band that is similar to rifle inner tube wall structure that in succession occurred the in recent years UPVC spiral hush pipe of spiral bar, so that falling water flow have to a certain degree along the inner tube wall swirling flow and lower effect, it is higher that but UPVC spiral hush pipe spiral bar can't be made, the falling water flow overwhelming majority still is in chaotic state in the pipe, the pipe end spiral bar is outstanding and without fillet, very easily tangle various foreign material, cause line clogging.
Summary of the invention
The purpose of this utility model is the shortcoming that overcomes prior art, provide a kind of and can make the lasting spiral-falling of current in the soil stack, the centrifugal force that current rely on spiral-falling to form is close to inner tube wall and is flowed, avoid the flow impact phenomenon to occur, reduce the construction drainage standpipe swirling-flow noise-reduction joint of draining noise.
For achieving the above object, the technical solution of the utility model is: a kind of construction drainage standpipe swirling-flow noise-reduction joint, comprise adapter body, formed by dilatation connecting body and swirling flow cone, dilatation connecting body top is provided with the main riser interface, the bottom is provided with swirling flow cone interface, the side is provided with horizontal interface tube, horizontal interface tube links to each other with the dilatation connecting body by the water conservancy diversion water channel, and main riser interface integral body places the dilatation connecting body inner, and dilatation connecting body external diameter is greater than the external diameter of main riser interface, the swirling flow cone is coniform, swirling flow cone top is provided with dilatation connecting body interface, and inwall is provided with the swirling flow blade, and the bottom is provided with the main riser interface.
Described dilatation connecting body and swirling flow cone are connected to each other moulding for after being separately made;
Described water conservancy diversion water channel is spiral stream guidance structure;
Described water conservancy diversion water channel is the straight line flow guide structure;
Described horizontal interface tube is more than 0 or 1 or 1.
The outstanding advantage of the utility model is: 1, the swirling flow cone structure with the swirling flow blade is up big and down small, so both had the current of making and presented the swirling flow state, again so that rotary water current presents the state that compiles reinforcement, the current of rotation rely on centrifugal action to be close under the inner-walls of duct rotating flow, the air passageways that pipeline center's self-assembling formation is unimpeded, reduce the bump of air and current, greatly promoted ventilation and the drainage capacity of pipeline, and effectively reduced the flowing water noise; 2, the main riser connection mouth integral body on the dilatation connecting body places the dilatation connecting body inner, reached the overflow that blocks horizontal arm current formation rotates the downflow flowing impact on main riser effect on the structure, and guide horizontal arm current at first to spread expansion, and then realize swirling flow and conflux through the swirling flow water body, to reach the effect consistent with flow direction in the main riser, improve the stability of current in the main riser, promoted the lifting of whole pipe drainage ability.

Embodiment
As Figure 1-3, a kind of construction drainage standpipe swirling-flow noise-reduction joint, comprise adapter body, formed by dilatation connecting body 1 and swirling flow cone 2, dilatation connecting body 1 top is provided with main riser interface 3, the bottom is provided with swirling flow cone interface 11, the side is provided with horizontal interface tube 4, horizontal interface tube 4 links to each other with dilatation connecting body 1 by water conservancy diversion water channel 5, and main riser interface 3 integral body place dilatation connecting body 1 inside, and dilatation connecting body 1 external diameter is greater than the external diameter of main riser interface 3, swirling flow cone 2 is coniform, swirling flow cone 2 tops are provided with dilatation connecting body interface 21, and inwall is provided with swirling flow blade 6, and the bottom is provided with main riser interface 3.
Described dilatation connecting body 1 and swirling flow cone 2 are connected to each other moulding for after being separately made;
Described water conservancy diversion water channel 5 is spiral stream guidance structure;
