Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in the following figures, a PVC drain pipe for amortization, including PVC body 8, the PVC body includes outer pipe 1 and inlayer pipe 2, inlayer pipe 2 with one heart in outer pipe 1, evenly set up a plurality of backup pads 5 along the circumferencial direction in the inlayer pipe 2, the one end fixed connection of backup pad 5 is on inlayer pipe 2 lateral wall, and the other end cross connects in the geometric centre of PVC body, fixed setting has the direction muscle 3 that leads rivers on the inlayer pipe 2 lateral wall, fixed being equipped with amortization groove 4 between outer pipe 1 and the inlayer pipe 2, the fixed amortization silver 7 that is equipped with in the amortization groove, amortization groove 4 both sides fixed mounting acoustic celotex 6, fixed connection glue layer 9 on the acoustic celotex 6 outer wall.

Fixed setting has the direction muscle 3 that leads to rivers on the 2 lateral walls of inlayer pipe, and direction muscle 3 can lead at the flow in-process to the water in the drain pipe, reduces the water because unordered flow strikes the drain pipe and the noise that arouses.

The sound-proof double-layer silencer is characterized in that a silencing groove 4 is fixedly arranged between the outer-layer pipe 1 and the inner-layer pipe 2, sound insulation boards 6 are fixedly arranged on two sides of the silencing groove 4, and the sound-proof effect is further improved through double-layer silencing of the silencing groove 4 and the sound insulation boards 6.

The silencing cotton strip 7 is fixedly arranged in the silencing groove 4, and the noise generated when water circulates in the drainage pipe can be absorbed through the silencing cotton strip 7, so that the noise is effectively reduced.

The 3 equidistance of direction muscle evenly set up in on the inner wall of inlayer pipe 2, direction muscle 3 is the heliciform, and the helix angle of direction muscle 3 is at 30-60, and the in-process of the waste water from high-order to low-order whereabouts in the drain pipe, 3 water in the geminate transistors of direction muscle divide gradually, because direction muscle 3 is the heliciform, water is downward along the inner wall spiral of inner tube to reduce the impact number of times each other of rivers in the intraductal, and then reduce the water that produces and the produced noise of pipe wall impact each other when the drainage strikes downwards.

The guide ribs 3 are made of rubber with good toughness, the number of the guide ribs 3 is 3-8, and the PVC drain pipe is firmer, not easy to break and strong in pressure resistance due to the arrangement of the 3-8 guide ribs 3.

The outer wall of the sound insulation board 6 is connected with a glue layer 9, the sound insulation board 6 is connected to the outer layer pipe 1 and the inner layer pipe 2 of the PVC drain pipe through the glue layer 9, the glue layer 9 is made of non-setting adhesive, and the sound insulation board can be directly adhered to the inner layer pipe 1 and the outer layer pipe 2 of the drain pipe.
