Noise-reducing drainage pipe and connecting pipe joint
The invention relates to a noise-reducing drainage pipe and a connecting pipe joint; the noise-reducing drainage pipe and the connecting pipe joint are each provided with a buffer structure; each buffer structure comprises a gradually shrinking section a straight pipe section, a gradually expanding section and a flow baffle; the gradually shrinking sections and the gradually expanding sections areformed in a horn shape; the large-caliber end of each gradually shrinking section is connected with the drainage pipe; the other end of each gradually shrinking section is connected with the corresponding straight pipe section; the other end of the straight pipe section is connected with the small-caliber end of the corresponding gradually expanding section; the large-caliber end of the graduallyexpanding section is connected with the drainage pipe; each flow baffle is arranged at the joint of the corresponding gradually expanding section and the drainage pipe; each flow baffle is formed ina conical shape; the large-diameter bottom of each flow baffle is connected with the drainage pipe; and the top of the flow baffle is arranged inside the corresponding gradually expanding section. According to the noise-reducing drainage pipe and the connecting pipe joint provided by the invention, by arranging the buffer structures, water dropping from a hollow part of the drainage pipe drops onthe flow baffle, flows along a conical surface and then obliquely flows to the wall, positioned below the flow baffle, of the drainage pipe so that the water dropping from the hollow part of the drainage pipe is transferred to the wall of the drainage pipe, then the water flows downstream, and noises are reduced.
本发明涉及一种消音排水管及连接管头，均设置有缓冲结构；缓冲结构包括渐缩段、直管段、渐扩段以及挡流板；渐缩段与渐扩段设置为喇叭状，渐缩段口径大一端连接排水管，另一端与直管段连接，直管段另一端与渐扩段口径小的一端连接，渐扩段口径大的一端与排水管连接；挡流板设置在渐扩段与排水管连接处；挡流板设置为圆锥状，直径大的底部与排水管连接，顶部设置在渐扩段内。本发明通过设置缓冲结构，使排水管中空部分掉落的水落到挡流板上，沿着锥形面流动，再倾斜流到挡流板下方的排水管的管壁上，使得从排水管中空部分掉落的水转移到排水管的管壁上，顺流而下，减小噪音。
