Part technical field.
Background technology
PVC-U pipeline is as primary raw material with Sanitary PVC (PVC) resin, adds appropriate stabilizer, lubrication
Agent, filler, toner etc. are through plastic extruder extrusion molding and injection machine injection mo(u)lding, by cooling down, solidify, shape, examining
Test, the operation such as packaging to be to complete the production of tubing, pipe fitting.Physical and chemical performance is excellent, resistance to chemical attack, and shock strength is high, and fluid hinders
Power is little, relatively with bore cast iron pipe flow improve 30%, ageing-resistant, service life is long, and service life is not less than 50 years, be build to
The ideal material of draining.
Along with the fast development of economic construction, high-rise gets more and more, and floor is more and more higher, gives people simultaneously
Also some are created worried, owing to along with the increase of floor, the noise produced during its drainage pipeline draining is also opened bigger and bigger, especially
It is night, the noise produced during draining downward from high level, have a strong impact on the rest of people and the peacefulness in room.Therefore one is sought
Can reduce the noise in drainage procedure, the drain pipe of the quality of the life improving people is particularly important.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of PVC-U noise cancelling type draining for above-mentioned prior art
Tubular construction, it can effectively reduce the noise in drainage procedure, improve the quality of the life of people.
The technical scheme in the invention for solving the above technical problem is: a kind of PVC-U noise cancelling type drain structure, it
Including outer layer pipe and inner layer pipe, it is connected by multiple annular dowels between described outer layer pipe and inner layer pipe, institute
Stating and be coated with multiple support rod between multiple annular dowel, the plurality of support rod is axially disposed, the plurality of
It is filled with sound-absorbing material outside support rib, described inner layer pipe inwall is provided with multiple water conservancy diversion raised line, adjacent two water conservancy diversion raised lines
Between formed diversion groove, be provided with auxiliary flow guide bar in the middle of described diversion groove, the height of described water conservancy diversion raised line is inner tube
The 1/5 ~ 1/3 of road internal diameter, the height of described auxiliary flow guide bar is the 1/3 of water conservancy diversion raised line height, the cross section shape of described water conservancy diversion raised line
Shape is triangle, and the cross sectional shape of described auxiliary flow guide bar is circular arc.
The width of described water conservancy diversion raised line is equal with the tube wall of inner layer pipe, and the width of described diversion groove is water conservancy diversion raised line
3 ~ 6 times of width.
The quantity of described water conservancy diversion raised line is 6 ~ 8.
Compared with prior art, the utility model has the advantage of:
This utility model one PVC-U noise cancelling type drain structure, by multiple between its inner layer pipe and outer layer pipe
Annular dowel is connected, it is possible to effectively strengthen the comprcssive strength of pipeline, improves the impact property of pipeline；Inner layer pipe and outer layer
It is filled with sound-absorbing material between pipeline, inner layer pipe inwall is provided with multiple water conservancy diversion raised line and auxiliary flow guide bar, it is possible to effectively
The noise produced when reducing draining；It is coated with multiple support rod, it is possible to inner layer pipe with outer between multiple annular dowels
