Description
Technical field
The utility model relates to a kind of PVC-U silencing drainage pipe.
Background technique
The waste pipe that construction engineering is used, when draining downward from a high position, because water Shu Yushui restraints, water bundle and waste pipe inwall mutual shock in the process of naturally falling can produce noise.Along with the development of economic construction, modern building floor is more and more higher, and the living standard of people also improves gradually, but for the waste pipe of high level, because floor is higher, the noise produced in waste pipe is also increasing, adds many worries to people.Therefore you seek a kind of noise that can reduce in drainage procedure, and the waste pipe improving the quality of the life of people is particularly important.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of noise that can reduce in drainage procedure, improves the PVC-U silencing drainage pipe of the quality of the life of people.
The purpose of this utility model is achieved in that
A kind of PVC-U silencing drainage pipe, it comprises body, the inner tubal wall of described body is provided with spiral bar, described spiral bar comprises the first spiral bar and the second spiral bar, the helix angle of described first spiral bar and the second spiral bar is 1.5 ~ 2 degree, the number of described first spiral bar is 12 ~ 20, the number of described second spiral bar is 4 ~ 6, the height of described first spiral bar is lower than the height of the second spiral bar, be provided with multiple hollow cavity be circular layout in described body, have the end of part first spiral bar to be provided with spiral elastic conducting flow.
Preferred as one, the shape of described hollow cavity is oval.
Preferred as one, the height of described first spiral bar is 0.5 ~ 0.6cm, and the height of described second spiral bar is 1 ~ 1.2cm, and the height of described elastic conducting flow is 1 ~ 2cm.
Compared with prior art, the beneficial effects of the utility model are:
The utility model is provided with multiple first spiral bar and the second spiral bar due to the inner tubal wall of body, when making draining, water bundle presses close to inner tube wall flowing by the guiding of spiral bar, water Shu Yushui is avoided to restraint, shock between water bundle and waste pipe inwall, reduce noise, coordinate elastic conducting flow in addition, make also can reduce water impact intensity, decrease rigid impulse and reduce noise, body is provided with hollow cavity, even if there is a little noise to produce, hollow cavity also again by noise absorption, can play the effect of secondary noise reduction.Therefore this PVC-U silencing drainage pipe has the noise that can reduce in drainage procedure, improves the advantage of the quality of the life of people.
