Abstract
A secondary swirl noise reducing joint for construction drainage comprises a joint main body. Main vertical pipe interfaces are arranged at the top and the bottom of the joint main body and a horizontal branch pipe interface is arranged on the side surface thereof. The joint main body comprises a horizontal branch pipe connector, an upper main vertical pipe connector and a lower main vertical pipe connector; a lower flow guiding sleeve is arranged in a funnel; a spiral rib (2) is arranged on the inner wall of the lower guiding sleeve; the outer diameter phi1 of the horizontal branch pipe connector is larger than the outer diameters of the upper and the lower main vertical pipe interfaces phi2; and the horizontal branch pipe interface is connected with the horizontal branch pipe connector through a spiral flow guidance water channel. The noise reducing joint is characterized in that an upper flow guiding sleeve is arranged in a lower opening of the upper main vertical pipe connector, and a spiral rib (1) is arranged on the inner wall of the upper flow guiding sleeve. The proposal enables the main vertical pipe spiral water flow to always keep continuous in the joint, the branch pipe water flow converges with the main vertical pipe spiral water flow through a spiral water channel, and rotationally flows down along the inner wall of the pipe together with main vertical pipe spiral water flow, so as to avoid the collision between the branch pipe water flow and the vertical pipe water flow, and ensure that the vertical pipe water flow always spirally falls, thereby reducing the noise of a pipe system.
Description
Technical field
The utility model relates to the construction drainage union, particularly relates to used in construction drainage secondary swirling-flow noise-reduction joint, is used to improve the architectural drainage system operating mode, improves the soil stack water passing capacity, reduces the current noise.
Background technology
Because UPVC gutter inwall is comparatively smooth, current are difficult for forming moisture film and flow along tube wall, are mix bump tube wall in pipeline; And UPVC gutter tube wall is thinner than the cast iron pipe tube wall of same specification, be 4.0mm as the former of DN110, and the latter is 5.5mm.The UPVC pipe just can not stop the transmission of noise effectively like this, brings " unpeaceful " factor for user's life.Therefore, Development and Production UPVC helical silencing pipe, the muscle rib of the helical form projection of the regular arrangement of its inwall, pipeline is increased the attached wall resistance of current, so just can forcibly make current be the moisture film shape along tube wall flows, reduced bump to tube wall, because the special tectonic of helix tube, reduce water velocity and reduced the overflow resistance coefficient, keep central gas core up/down perforation in the standpipe, steady pressure oscillation in the standpipe has reduced modal negative pressure suction and positive pressuring spraying base in the soil stack effectively, water passing capacity is greatly enhanced, and greatly reduces the current noise.But its shortcoming is standpipe and horizontal arm junction, causes the junction to form overflow stream easily, makes the cutout of main riser spiral water flow, and horizontal arm current are not smooth, and the drainage system air pressure fluctuation is big, greatly reduces the water passing capacity and the noise reduction of helical silencing pipe.Therefore, the inventor has designed and a kind ofly down has been equipped with the water conservancy diversion cover in the main riser connector, and water conservancy diversion cover inwall is shaped on spiral bar, has overcome the overflow flow problem of standpipe and horizontal arm junction, and has made horizontal arm current unobstructed.In last main riser connector, be smooth inner wall still, surface helix current are down changed, make noise reduction incomplete.
Summary of the invention
The purpose of this utility model is in order to overcome the shortcoming of prior art, provide a kind of main riser spiral water flow in joint, to remain continuity, the arm current converge through spiral channel and main riser spiral water flow, together along under the pipe material inner wall rotating flow, avoid the collision of arm current and standpipe current, guarantee standpipe current helical form whereabouts all the time, reduce the pipe-line system noise, and can be connected the used in construction drainage secondary swirling-flow noise-reduction joint in the smooth inner wall gutter.
The technical scheme of the utility model used in construction drainage secondary swirling-flow noise-reduction joint is: comprise adapter body, the upper and lower of main body has main riser interface and side that horizontal interface tube arranged, described adapter body comprises horizontal arm connector, goes up main riser connector and following main riser connector, following main riser connector is round table-like funnel type, following water conservancy diversion cover is arranged in funnel type, the inwall of following water conservancy diversion cover is shaped on spiral bar second, horizontal arm connector external diameter Φ
1External diameter Φ greater than upper and lower main riser interface
2, horizontal interface tube links to each other with horizontal arm connector through the spiral stream guidance water channel, and it is characterized in that has last water conservancy diversion cover in the end opening of main riser connector, and the inwall of last water conservancy diversion cover is shaped on the spiral bar first.
The beneficial effect of the utility model used in construction drainage secondary swirling-flow noise-reduction joint is: 1, the last water conservancy diversion cover that the band spiral bar is arranged in the main riser connector end opening on it, following main riser connector profile is funnel type, inside has than large space, in establish the band spiral bar funnel type under the water conservancy diversion cover, become deuterostrophies water conservancy diversion joint, really make the unlikely cutout of main riser spiral water flow, strengthened on the contrary, force current along under the pipe material inner wall rotating flow, reduce the collision of current and air, the direction of standard fluid, reduce " water hammer " influence, in the middle of tubing, form a unimpeded air column, improve the ventilation capacity of pipeline greatly, simultaneously also improve drainability greatly, reduced the noise of current.2, horizontal the interface tube that single or multiple band spiral stream guidance water channels are arranged, can admit the horizontal arm current of a plurality of directions simultaneously, after horizontal arm current are through the spiral channel water conservancy diversion, form spiral water flow, enter on the taper surface that has spiral bar funnel type water conservancy diversion cover first, the spiral water flow that obtains further swirling flow reinforcement back and main riser converges, together along under the pipe material inner wall rotating flow, the water inlet of horizontal arm can not produce the crossing current overflow that disturbs the standpipe spiral water flow, avoided the collision of arm current and standpipe current, weakened the bubble that produces when changing from water exhaust air because of the system internal pressure, guaranteed standpipe current helical form whereabouts all the time, thereby reduced the noise of pipe-line system, and increased drainability.This secondary swirling-flow noise-reduction joint also can be supporting with common UPVC smooth inner wall gutter, reduces noise.
Used in construction drainage secondary swirling-flow noise-reduction joint of the present utility model, its described upward main riser connector and last water conservancy diversion cover are to be separately made the back bonding forming, handling ease is made in split.Between last main riser connector and horizontal arm connector, linkage can be arranged, between main riser connector and the horizontal arm connector linkage can arranged also down, described linkage comprises interface, socket, slot, plug, bayonet socket, various structures and approach such as bonding, linkage has been arranged, and it is firm to connect.
