Description
Technical field
The utility model relates to pipe technology field, specifically a kind of PVC-U drainage pipeline with mute function.
Background technique
As town and country construction develops, drainpipe is more and more used in household building industry, and existing drainpipe is being arranged
During water, because between water flow collision or with the collision of duct wall, generate biggish noise, sound is very noisy, give resident
Life bring certain inconvenience.The noise that traditional PVC-U drainage pipeline not only generates is larger, and on service life
It is also not fully up to expectations.
Therefore it needs to improve existing drainage pipeline.
Utility model content
To solve the above-mentioned problems, the utility model discloses a kind of PVC-U drainage pipeline with mute function.
The technical solution of the utility model are as follows: the PVC-U drainage pipeline with mute function, including drain body, row
It is drainage cavity in the middle part of water-pipe body, drainage cavity inner body wall is equipped with flow guide bar, and flow guide bar two sides are equipped with spherical groove, flow guide bar
The outside of corresponding drain body is equipped with reinforcing rib, outer tube is equipped on the outside of drain body, between outer tube and drain body
Filled with fibrous layer, being full of in fibrous layer has vacuum chamber, and drain body includes draining upper tube and draining down tube, drains upper tube
Drainage cavity diameter is less than draining down tube, and draining upper tube and draining down tube are directly attached by screw thread.
Preferably, flow guide bar is the spiral helicine raised line higher than drain body around draining cavity wall, flow guide bar and
Reinforcing rib is corresponding in turn to.
Preferably, sound-absorbing core has been filled or unfilled in vacuum chamber.
Preferably, threaded connection place is equipped with sealing ring.
Preferably, the depth of spherical groove is less than the wall thickness of drain body.
The usefulness of the utility model: medium is needed according to the propagation of sound, the application is equipped with vacuum in fibrous layer
Chamber, fibrous layer itself have soundproof effect, and vacuum chamber is even more the propagation for having blocked sound, when water flow flows through, flow guide bar
Can reduce flow velocity and impact force, groove can reduce water flow and drain the shock of cavity wall, reduce sound, water flow flow down when
It waits, drainpipe is up-thin-low-thick, is further reduced the shock with inner wall, moreover it is possible to play the role of transition, can more improve drainpipe
Service life, to sum up, the application soundproof effect are good, effectively improve the service life of muting function and drainpipe.

Specific embodiment
In order to deepen the understanding to the utility model, the specific embodiment party of the utility model is described in detail with reference to the accompanying drawing
Formula, the embodiment are only used for explaining the utility model, do not constitute the restriction to the protection scope of the utility model.
PVC-U drainage pipeline with mute function, including drain body 1 are drainage cavity 5 in the middle part of drain body 1,
5 inner body wall of drainage cavity is equipped with flow guide bar 6, and 6 two sides of flow guide bar are equipped with spherical groove 8, and the depth of spherical groove 8 is less than draining
The wall thickness of tube body 1, the outside of the corresponding drain body 1 of flow guide bar 6 are equipped with reinforcing rib 7, and flow guide bar 6 is higher than drainpipe sheet
The spiral helicine raised line around 5 inner wall of drainage cavity of body 1, flow guide bar can reduce flow velocity and impact force, flow guide bar 6 and reinforcing rib
7 are corresponding in turn to, and outer tube 2 is equipped on the outside of drain body 1, and fibrous layer 9, fibrous layer are filled between outer tube 2 and drain body 1
Being full of in 9 has vacuum chamber 91, sound-absorbing core has been filled or unfilled in vacuum chamber 91, fibrous layer itself has soundproof effect, vacuum
Chamber is even more the propagation for having blocked sound, and drain body 1 includes draining upper tube 3 and draining down tube 4, drains the drainage cavity 5 of upper tube 3
Diameter is less than draining down tube 4, and drainpipe is up-thin-low-thick, is further reduced the shock with inner wall, moreover it is possible to play the role of transition, more
The service life of drainpipe can be improved, draining upper tube 4 and draining down tube 4 are directly attached by screw thread, and threaded connection place is set
There is sealing ring, be connected through a screw thread, moreover it is possible to be convenient for dismounting inspection etc..
