Embodiment Construction

[0010] The invention relates to a swirl flow noise reduction joint for building drainage, such as figure 1 — image 3 As shown, it includes the main body of the joint. There are main riser joints 1 on the upper and lower sides of the main body and lateral branch joints 2 on the side. The main riser connector 8, the lower main riser connector 8 is in the shape of a circular platform funnel, and there is a lower diversion sleeve 5 in the funnel shape, and the inner wall of the lower diversion sleeve 5 is formed with spiral ribs B4, and the transverse branch pipe connector 7 outer diameter Φ 1 Greater than the outer diameter Φ of the upper and lower main riser joints 1 2 , the transverse branch pipe interface 2 is connected to the transverse branch pipe connecting body 7 through the spiral diversion channel 3 . Compared with the prior art, this program has the following advantages: 1. The lower main riser connector 8 is funnel-shaped in shape, has a larger space inside, and ha...

Abstract

The invention relates to a swirling-flow noise-reduction joint used in construction drainage, which comprises a joint main body. The main body is provided with main raiser joints respectively at the upper and the lower parts and a cross branch joint at the sides. The invention is characterized in that the joint main body comprises a cross branch connector, an upper main raiser connector and a lower raiser connector; the lower main raiser connector is in funnel type and looks like a round platform; a lower guide sleeve is arranged in the funnel-type lower main raiser connector, and the inner wall of the lower guide sleeve is provided with a spiral hooping B. The outer diameter of the cross branch connector is larger than that of the upper and the lower main raiser joints; and the cross branch joint is connected with the cross branch connector through a spiral waterway. The proposal continues the overall main raiser spiral flow; and the branch flow and the main raiser spiral flow converge through the spiral waterway and whirl and flow down along the inner walls of pipes, thereby avoiding the crash between the branch flow and the raiser flow, guaranteeing the swirling falling of the raiser flow to reduce noise; in addition, the branch flow and raiser flow also can be connected in a UPVC draining pipe with smooth inner walls to reduce noise.

Description

technical field [0001] The invention relates to a building drainage pipe joint, in particular to a swirl flow noise-reducing joint for building drainage, which is used for improving the working condition of the building drainage system, improving the water flow capacity of the drainage riser and reducing water flow noise. Background technique [0002] Since the inner wall of the UPVC drainage pipe is relatively smooth, the water flow is not easy to form a water film to flow along the pipe wall, and it hits the pipe wall in a chaotic state in the pipe; moreover, the wall of the UPVC drainage pipe is thinner than that of the cast iron pipe of the same specification, such as the former of DN110. 4.0mm, while the latter is 5.5mm. In this way, the UPVC pipe cannot effectively prevent the transmission of noise and bring "uneasy" factors to the lives of users. Therefore, the UPVC spiral silencer pipe has been developed and produced, and its inner wall has spirally protruding ribs ...
