CN201651599U - Spiral hush pipe - Google Patents

Abstract

The utility model relates to a spiral hush pipe, which is characterized in that spiral ribs are formed on the inner wall of the hush pipe in a linear, obliquely and uniformly distributed way, and the included angle between each spiral rib and the hush pipe ranges from 8 DEG to 20 DEG. The spiral hush pipe has the characteristic that the spiral ribs are formed on the inner wall of the hush pipe in the linear, obliquely and uniformly distributed way, so that when water is discharged, water flowing under the diversion of the spiral ribs is discharged along the inner wall of the pipe according to the oblique straight lines of the spiral ribs, and has lesser impact on the inner wall, and the noise is lower; and since the included angle between the spiral rib and the center line of the hush pipe ranges from 8 DEG to 20 DEG, the effect of noise damping can be achieved, and water drainage is facilitated.

Description

The helical silencing pipe

Technical field

The utility model relates to a kind of helical silencing pipe, belongs to the tubing technical field.

Background technique

Therefore simple in structure, the low cost of manufacture of plastic tube commonly used at present is widely used; But during as the waste pipe of high building resident family, because of pipe is vertically installed, and its inner wall smooth, tube wall is subjected to water impact and produces bigger noise during draining, influences the normal rest of resident family downstairs.

Summary of the invention

The purpose of this utility model is in order to overcome the shortcoming of prior art, the little helical silencing pipe of noise that produces when a kind of draining is provided.

The technological scheme that the utility model adopted is to achieve the above object of the invention:

The helical silencing pipe is characterized in that being shaped on the pipe material inner wall spiral bar, and spiral bar is linearly oblique uniform, and with the angle of hush pipe center line be 8 °-20 °.

The utility model relates to a kind of helical silencing pipe, be characterized on pipe material inner wall, being shaped on linearly oblique uniform spiral bar, during draining, current are under the water conservancy diversion of spiral bar, oblique straight line by spiral bar is discharged along pipe material inner wall, can not produce stronger impact, so noise is smaller to its inwall; The angle of spiral bar and hush pipe center line is 8 °-20 °, can reach the effect of noise reduction, helps draining again.

Described tubing is made by PVC, and mechanical strength is big.

Fig. 2 is the utility model is cut state open along the tubing wall a tiling schematic representation.

Embodiment

The utility model relates to a kind of helical silencing pipe, as depicted in figs. 1 and 2, is shaped on spiral bar 2 on the pipe material inner wall 1, and described spiral bar 2 is linearly oblique uniform, and with the angle α of hush pipe center line be 8 °-20 °; The utility model relates to a kind of helical silencing pipe, be characterized on pipe material inner wall 1, being shaped on linearly oblique uniform spiral bar 2, during draining, current are under the water conservancy diversion of spiral bar 2, pressing the oblique straight line of spiral bar 2 discharges along pipe material inner wall 1, can not produce stronger impact, so noise is smaller to its inwall 1; Spiral bar 2 is 8 °-20 ° with the angle α of hush pipe center line, can reach the effect of noise reduction, helps draining again.Described tubing is made by PVC, and mechanical strength is big.

Claims (2)

1. the helical silencing pipe is characterized in that being shaped on spiral bar (2) on the pipe material inner wall (1), and spiral bar (2) is linearly oblique uniform, and with the angle (α) of hush pipe center line be 8 °-20 °.

2. helical silencing pipe according to claim 1 is characterized in that described tubing made by PVC.
