Abstract
The utility model discloses a silencing antistatic enhanced drain pipe which is a concentric double layer pipe formed by an antistatic inner layer pipe body and an outer layer pipe body. A spiral diversion channel which is raised towards the center of the pipe is arranged on the inner wall of the inner layer pipe body, enables drained water to be gradually diverted from a high position to a low position, enables fluid which enters the diversion channel to spirally flow down and enables fluid which does not enter the diversion channel to straightly flow down, and the speed of the fluid straightly flowing down is faster than that of the fluid spirally flowing down, therefore, sound generated by shock between water and water as well as the water and the pipe wall when the water shocks downwards is inhibited, and noise of a foam layer between the inner layer pipe body and the outer layer pipe body is also reduced; and in addition, a stiffener between the inner layer pipe body and the outer layer pipe body enables the compressive strength and the shock resistance capability of the pipe to be strengthened. Because the inner layer of the pipe body is an antistatic pipe body inner layer, the utility model can be used in the antistatic environment and has the advantages of simple structure, low manufacture cost and easy popularization.
Description
[technical field]
The utility model relates to a kind of construction drainage pipe, particularly a kind of waste pipe with good erasure effect, resistance to compression and antistatic excellent in cushion effect.
[background technique]
Fast development along with building industry, structural material on the market is more and more, water drainage plastics pipe for building, because inner-walls of duct is smooth especially, the fluid during draining in the pipe and fluid, fluid and tube wall clash into the noise that is produced mutually and have a strong impact on people's the rest and the peacefulness in room in natural process;
Existing body often is an individual layer, and the compressive strength of pipe is low, a little less than the impact resistance, and this has limited the working life of pipe greatly;
Simultaneously, existing waste pipe is not antistatic, has limited its use in antistatic environment.
[model utility content]
Goal of the invention of the present utility model is: at the problem of above-mentioned existence, provide the waste pipe of a kind of good muffling effect, resistance to compression and antistatic excellent in cushion effect.
The present invention seeks to realize by the enforcement following technical proposals:
The antistatic enhancing waste pipe of a kind of noise reduction is the concentric double tubes of antistatic internal layer body and outer body composition, and the inwall of described internal layer body is provided with the spiral stream guidance road to the tube hub projection.
As preferably, described spiral stream guidance road section semicircular in shape, involute profile, rectangle or triangle.
As preferably, between described internal layer body and outer body, be provided with foaming layer.
As preferably, described foaming layer is the plastic foamed layer of fine and closely woven closed pore.
As preferably, described foaming layer is made up of one or more foaming layers of PVC, polyurethane, polystyrene, polyethylene, polypropylene, phenolic aldehyde, epoxy and unsaturated polyester ester foamed plastic.
As preferably, between internal layer body and outer body, be provided with stiffening rib.
As preferably, described stiffening rib is at least 3.
As preferably, the helix angle in described spiral stream guidance road is the 5-60 degree.
As preferably, described internal layer body is the inner plastic body that has added anti-static agent.
Wherein, the spiral stream guidance road can make draining progressively shunt from a high position to the low level, make and enter water conservancy diversion conduit fluid spiral and descend, and do not enter the fluid straight line of honeycomb duct and descend, fluid ratio spiral under straight and under liquid speed fast, the water and the water that have suppressed generation when water impacts so downwards, the sound that water and tube wall impact, foam layer between the simultaneously inside and outside body has reduced noise, stiffening rib between the inside and outside body is improved the compressive strength of pipe and impact resistance, because the body internal layer is antistatic body internal layer, so can use in the environment of antistatic, the utility model is simple in structure, low cost of manufacture is easy to promote.

[embodiment]
Below in conjunction with accompanying drawing, the utility model is done detailed explanation.
Embodiment 1
As shown in Figure 1, the antistatic enhancing waste pipe of a kind of noise reduction is the concentric double tubes of antistatic internal layer body 1 and outer body 2 compositions, and the inwall of described internal layer body is provided with the spiral stream guidance road 5 to the tube hub projection, spiral stream guidance road section semicircular in shape; Be provided with foaming layer 3 between described internal layer body and outer body, described foaming layer is the Vestolit foaming layer and is the plastic foamed layer of fine and closely woven closed pore.Be provided with stiffening rib 4 between internal layer body and outer body, described stiffening rib is 4.The helix angle in described spiral stream guidance road is 5 degree, and internal layer body 1 is for having added the inner plastic body of anti-static agent.
As shown in Figure 2, the antistatic enhancing waste pipe of this routine noise reduction, structure and embodiment 1 are basic identical, difference is: spiral stream guidance road section is involute profile, the foaming layer 3 of between described internal layer body 1 and outer body 2, establishing, for polystyrene foam plastics foaming layer and polyurethane foam layer are formed jointly, between internal layer body and outer body, be provided with stiffening rib 4, described stiffening rib is 3, the helix angle in described spiral stream guidance road is 60 degree, and described internal layer body 1 is for having added the inner plastic body of anti-static agent.
