Silencing swirling flow tee of single-spiral joint pipe

Abstract

A silencing swirling flow tee of a single-spiral joint pipe is characterized by comprising a main body of the tee, the main body is provided with an upper joint, a side spiral pipe and a lower joint, the upper joint is connected with an upper connection cover, the upper connection cover is provided with a bell and spigot outer pipe, the outer wall, positioned at the main body, of the side spiral pipe is provided with an arc bulge, the inner wall, positioned in the main body, of the side spiral pipe is provided with an inner sloping baffle and a lower baffle, a spiral hole is formed among the arc bulge, the inner sloping baffle and the lower baffle, the lower joint is connected with a swirling flow pipe, the swirling pipe comprises a bell and spigot inner pipe at the upper part, the bell and spigot inner pipe is in insertion match with the inner wall of the lower joint, a circular truncated cone pipe is arranged at the bell and spigot inner pipe, a lower straight pipe is arranged under the circular truncated cone pipe, a lower bell and spigot pipe is arranged under the lower straight pipe and arch and oblique swirling blades are arranged at the inner walls of the circular truncated cone pipe and the lower straight pipe.

Description

technical field [0001] The invention relates to a plastic pipe fitting, in particular to a sound-absorbing swirl tee pipe with a single spiral joint. Background technique [0002] Ordinary drainage pipe fittings mostly have smooth inner walls, and the water flow falls vertically in the pipe, showing a chaotic state. The chaotic water flow easily collides with the pipe wall to generate noise, which affects people's lives. Therefore, someone invented the sound-absorbing pipe fitting, but the existing sound-absorbing pipe fittings usually only have spaced ring pieces and ring grooves on the outer wall of the pipe fitting. This structure cannot change the form of the water flow in the pipe fitting, but only makes the water flow hit the inner wall of the pipe fitting to reduce the noise transmitted to the outside world. , and in the quiet night, the noise is still more obvious, and its noise reduction effect is poor. Contents of the invention [0003] The purpose of the presen...
