CN201651598U - Hollow wall spiral hush pipe - Google Patents

Abstract

The utility model relates to a hollow wall spiral hush pipe which is characterized in that a pipe wall comprises an inner layer and an outer layer, wherein the inner wall and the outer wall are connected through ribs, spiral ribs are arranged on the inner wall of the inner layer of the pipe wall, and the spiral ribs are aslant distributed along the straight line and have an included angle of 8-20 degrees with a center line of the hush pipe. The hollow wall spiral hush pipe is characterized in that the pipe wall comprises the inner layer and the outer layer, and the spiral ribs uniformly aslant distributed along the straight line are arranged on the inner wall of the inner layer of the pipe wall, water is discharged along the inner wall of the inner layer of the pipe wall according to the aslant straight line of the spiral ribs under the guide of the spiral ribs during the drainage without generating stronger impact on the inner wall of the inner layer, therefore, the noise is smaller; the inner layer and the outer layer of the pipe wall are connected through the ribs to form sound insulation holes, water produces smaller noise on the inner layer of the pipe wall and then the noise is weakened by the sound insulation holes, thus drainage sound transferred to outside basically hardly interferes the normal rest of people; and the included angle of the spiral ribs and the center line of the hush pipe is 8-20 degrees, which can achieve the effect of noise reduction and is beneficial to drainage.

Description

Hollow wall helical silencing pipe

Technical field

The utility model relates to a kind of hollow wall 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 hollow wall helical silencing pipe that provides a kind of tube wall to have sound insulation and noise reduction.

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

Hollow wall helical silencing pipe, it is characterized in that tube wall is made of inside and outside layer, inside and outsidely connect by rib between two-layer, be shaped on spiral bar on the inwall of tube wall internal layer, described spiral bar linearly oblique uniform and with the angle of hush pipe center line be 8 °-20 °.

The utility model relates to a kind of hollow wall helical silencing pipe, be characterized in that tube wall is made of inside and outside layer, on the inwall of tube wall internal layer, be shaped on linearly oblique uniform spiral bar, during draining, current are under the water conservancy diversion of spiral bar, press the oblique straight line of spiral bar and discharge, can not produce stronger impact, so noise is smaller its inwall along the inwall of tube wall internal layer; The inside and outside connection by rib between two-layer of described tube wall forms the sound insulation hole, and the less noise that water produces the tube wall internal layer is again by the weakening effect in sound insulation hole, and the draining sound that passes to the external world can not disturb the people normally to have a rest basically; 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.

Embodiment

The utility model relates to a kind of hollow wall helical silencing pipe, as depicted in figs. 1 and 2, it is characterized in that tube wall is made of inside and outside layer 1,2, inside and outsidely connect by rib 3 between two-layer, be shaped on spiral bar 4 on the inwall 11 of tube wall internal layer 1, described spiral bar 4 is linearly oblique uniform, and with the angle α of hush pipe center line be 8 °-20 °; Characteristics of the present utility model are that tube wall is made of inside and outside layer 1,2, on the inwall 11 of tube wall internal layer 1, be shaped on linearly oblique uniform spiral bar 4, during draining, current are under the water conservancy diversion of spiral bar 4, pressing the oblique straight line of spiral bar 4 discharges along the inwall 11 of tube wall internal layer 1, can not produce stronger impact, so noise is smaller to its inwall 11; The inside and outside connection by rib 3 between two-layer of described tube wall forms sound insulation hole 5, and the less noise that water produces tube wall internal layer 1 is again by the weakening effect in sound insulation hole 5, and the draining sound that passes to the external world can not disturb the people normally to have a rest basically; Spiral bar 4 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)
