Description
Technical field
The utility model is related to a kind of pipe fitting, is specifically related to a kind of hollow silencing drainpipe, belongs to plastic pipe technology
Field.
Background technology
Drainpipe used by architectural engineering, when from high-order draining downwards, as water Shu Yushui is restrainted, in water bundle and drainpipe
Wall mutually clashes into during falling naturally and can produce noise.With the development of economic construction, modern building floor is more next
Higher, the living standard of people is also gradually stepped up, but for high-rise drainpipe, as floor is higher, is produced in drainpipe
Noise also increasing, give people to increased many worries.Therefore seek a kind of noise that can reduce in drainage procedure, carry
The drainpipe of the quality of the life of high people is particularly important.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of hollow silencing drainpipe for above-mentioned prior art,
It can effectively reduce the noise in drainage procedure, so as to improve the quality of the life of people.
The technical scheme in the invention for solving the above technical problem is：A kind of hollow silencing drainpipe, it include outer
Layer pipeline and inner layer pipe, are connected by multiple vertical connection gussets between the outer layer pipe and inner layer pipe, described interior
Multiple second spiral bars are provided with layer inner-walls of duct, the quantity of second spiral bar is consistent with the quantity of connection gussets, institute
The position for stating multiple second spiral bars is corresponded with the position of multiple vertical connection gussets respectively, two neighboring second spiral bar
Between be provided with the first spiral bar, be evenly arranged with multiple sound-absorbing hole on the internal face of the outer layer pipe.
The helical angle of first spiral bar and the second spiral bar is 20 ~ 70 °；
The cross sectional shape of first spiral bar is triangle, and the cross sectional shape of second spiral bar is circular arc.
The generally circular in shape or regular polygon of the sound-absorbing hole.
Compared with prior art, the utility model has the advantage of：
A kind of hollow silencing drainpipe of the utility model, by multiple vertical connections between its inner layer pipe and outer layer pipe
Gusset is connected, and can not only effectively strengthen the compression strength of pipeline, improves the impact property of pipeline, and simple structure, raw
Produce low cost；Cavity between inner layer pipe and outer layer pipe, is provided with the first spiral bar and the second spiral on inner layer pipe inwall
Muscle, is evenly equipped with multiple sound-absorbing hole on outer layer pipe internal face, can effectively reduce the noise produced during draining.
Description of the drawings

Specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing embodiment.
As shown in Figure 1 and Figure 2, a kind of hollow silencing drainpipe in the present embodiment, it includes outer layer pipe 1 and inner tube
Road 2, is connected by multiple vertical connection gussets 3 between the outer layer pipe 1 and inner layer pipe 2,2 inwall of the inner layer pipe
On be provided with multiple second spiral bars 5, the quantity of second spiral bar 5 is consistent with the quantity of connection gussets 3, the plurality of
The position of two spiral bars 5 is corresponded with the position of multiple vertical connection gussets 3 respectively, between two neighboring second spiral bar 5
The first spiral bar 4 is provided with, on the internal face of the outer layer pipe 1, is evenly arranged with multiple sound-absorbing hole 6.
The helical angle of first spiral bar 4 and the second spiral bar 5 is 20 ~ 70 °；
The cross sectional shape of first spiral bar 4 is triangle, and the cross sectional shape of second spiral bar 5 is circular arc；
The generally circular in shape or regular polygon of the sound-absorbing hole 6.
In addition to the implementation, the utility model also includes other embodiment, all employing equivalents or equivalent
The technical scheme that substitute mode is formed, all should fall within the utility model scope of the claims.
