Description

Mute water drainage pipe

The technical field is as follows:

the utility model relates to a silence drain pipe.

Background art:

each building is provided with a large number of drainage pipelines for collecting and discharging sewage, wastewater and rainwater. Current drain pipe is when the drainage, if discharge is very big, inside rivers can flow along the drain pipe inner wall fast, still can take place the striking with the drain pipe inner wall for the drain pipe produces great rivers sound externally, therefore very noisy. For people living in the building, if no sound insulation measure for the drain pipe is made, the people often suffer from noise pollution of the drain pipe in the living process and the living quality is influenced.

The invention content is as follows:

the utility model aims at solving the problem among the prior art, provide one kind and can shunt rivers, slow down the velocity of flow, body itself also has the silence drain pipe of giving sound insulation and sound deadening function.

In order to achieve the above purpose, the technical scheme of the utility model is that:

the utility model provides a silence drain pipe, is provided with the body of spiral drainage piece on the inner wall, the body includes interior puigging and outer sound absorption layer, interior puigging is interior to encircle and is provided with the vacuum pearl, outer sound absorption in situ is encircleed and is provided with the sound absorption chamber, it inhales the sound intracavity and installs and inhale the sound cotton, the external soft polyurethane foam protective layer that still overlaps of pipe.

And a sound absorption coating layer is arranged on the outer surface of the pipe body in the soft polyurethane foam plastic protective layer.

The surface of the spiral drainage sheet is uniformly provided with convex particles.

The outer sleeve of the sound-absorbing cotton in the sound-absorbing cavity is provided with a sizing sleeve.

The utility model has the advantages that: the utility model discloses a mute drain pipe, including the body that is provided with the spiral drainage piece on the inner wall, the spiral drainage piece shunts and guides the rivers inside the body, reduces the probability that rivers strike the inner wall, and the spiral drainage piece surface has evenly seted up protruding grain simultaneously, can slow down some rivers velocity of flow; the pipe body comprises an inner sound insulation layer and an outer sound absorption layer, vacuum beads are arranged in the inner sound insulation layer in a surrounding mode, and the vacuum beads are of vacuum structures inside and can achieve a good sound insulation effect; outer sound absorption in-layer is encircleed to be provided with and is inhaled the sound chamber, inhales the sound intracavity and installs and inhale the sound cotton, and the partial sound wave that passes inner sound insulation layer is through inhaling the cotton absorption of sound, and the external soft polyurethane foam protective layer that still overlaps of pipe is equipped with, and soft polyurethane foam protective layer also has certain sound function of inhaling when protecting the body, makes the drain pipe silence more.

Description of the drawings:

fig. 1 is a schematic structural diagram of the present invention.

The specific implementation mode is as follows:

in order that those skilled in the art will better understand the inventive arrangements, further details of the invention are provided below with reference to the accompanying drawings and embodiments.

The mute water drainage pipe shown in fig. 1 comprises a pipe body 1, wherein a spiral drainage piece 11 is arranged on the inner wall of the pipe body 1, the pipe body 1 comprises an inner sound insulation layer 2 and an outer sound absorption layer 3, and the spiral drainage piece 11, the inner sound insulation layer 2 and the outer sound absorption layer 3 can be made of the same material, such as PVC, PE, HDPE and the like. As a preferable scheme, the spiral diversion piece 11 is uniformly provided with convex particles 12 on the surface, and the convex particles 12 can slow down the flow velocity of part of the water flow, thereby reducing the sound of the water flow. The vacuum beads 21 are arranged in the inner sound insulation layer 2 in a surrounding mode, the vacuum beads 21 are beads with the interior in a vacuum state, and the vacuum beads are added into the inner sound insulation layer 2 when the inner sound insulation layer is manufactured and formed, so that a good sound insulation effect can be achieved. The outer sound absorption layer 3 is internally provided with a sound absorption cavity 31 in a surrounding manner, and sound absorption cotton 32 is arranged in the sound absorption cavity 31. Preferably, the shaping sleeve 8 is sleeved outside the sound absorption cotton 32 in the sound absorption cavity 31, the shaping sleeve 8 shapes the sound absorption cotton 32, and the sound absorption cotton 32 can be better fixed in the sound absorption cavity 31, so that the outer sound absorption layer 3 can be conveniently manufactured.

The flexible polyurethane foam plastic pipe is characterized in that a flexible polyurethane foam plastic protective layer 4 is further sleeved outside the pipe body 1, and a sound absorption coating layer 7 is arranged on the outer surface of the pipe body 1 in the flexible polyurethane foam plastic protective layer 4. The soft polyurethane foam plastic protective layer 4 has a certain sound absorption effect while protecting the appearance of the pipe body 1, and the sound absorption coating layer 7 adopts biological fibers, mineral fibers and the like as main raw materials and can also be combined with other fire retardants, moisture-proof agents, enzyme corrosion inhibitors and the like, so that the performance and the silencing effect of the pipe body 1 are improved.

The mute drain pipe comprises a pipe body, wherein the inner wall of the pipe body is provided with a spiral drainage sheet, the spiral drainage sheet divides and guides water flow in the pipe body, the probability that the water flow impacts the inner wall is reduced, and meanwhile, the surface of the spiral drainage sheet is uniformly provided with convex particles, so that the flow speed of partial water flow can be reduced; the pipe body comprises an inner sound insulation layer and an outer sound absorption layer, vacuum beads are arranged in the inner sound insulation layer in a surrounding mode, and the vacuum beads are of vacuum structures inside and can achieve a good sound insulation effect; outer sound absorption in-layer is encircleed to be provided with and is inhaled the sound chamber, inhales the sound intracavity and installs and inhale the sound cotton, and the partial sound wave that passes inner sound insulation layer is through inhaling the cotton absorption of sound, and the external soft polyurethane foam protective layer that still overlaps of pipe is equipped with, and soft polyurethane foam protective layer also has certain sound function of inhaling when protecting the body, makes the drain pipe silence more.
