Silencing and anti-freezing method and device for sewer line

Abstract

The invention relates to a silencing and anti-freezing method and a silencing and anti-freezing device for a sewer line, and belongs to the technical field of a building material. The silencing and anti-freezing device is characterized by comprising a sealed shell (1), a silencing material layer (2) and a damping material layer (3). The silencing and anti-freezing device is characterized in that a cavity (4) and a thick wall pipe body, wherein the cavity (4) which is matched with the outer diameter of a pipeline is formed in the center of the device, and the thick wall pipe body of a multi-layer structural surrounding body is formed by taking the cavity as the center; the multi-layer structural surrounding body is sequentially surrounded by the silencing material layer (2), the damping material layer (3) and the sealed shell (1) from inside to outside in such a way that at least one silencing material layer (2), the innermost damping material layer (3) and the outmost sealed shell (1) are arranged; the multi-layer structural surrounding body is formed by the surrounding bodies of more than two parts, and a way of connecting the two surrounding bodies is overlapping, i.e. the sections of the overlapping parts of the surrounding bodies are of step shapes which are mutually matched. The silencing and anti-freezing device provided by the invention can be repeatedly disassembled and installed without the need of professionals, is convenient to overhaul, tidy, delicate and attractive to decorate, and sound insulation, silencing and anti-freezing can be realized.

Description

technical field [0001] The invention relates to a noise reduction and antifreeze method and device for sewer pipes, belonging to the technical field of building materials. Background technique [0002] Most of the sewage pipes used in modern buildings are installed close to the wall, corner or horizontal pipe under the roof; one side faces the indoor central space, and the other side faces the wall, corner or roof with very little space. Most of the pipes are made of PVC plastic pipes, which will generate noise during the sewage drainage process on the upper floors of the building, especially in high-rise buildings, where the main sewage pipes on the lower floors have a higher frequency of noise overlap and more serious noise. What is more prominent is that the suspended horizontal sewage pipes under the roof are mainly toilet flushing and other sewage on the upper floor separated by one floor, and the sewage is discharged vertically downwards initially, sudden noise, and se...

AI Technical Summary

Problems solved by technology

What is more prominent is that the suspended horizontal sewage pipes under the roof are mainly toilet flushing and other sewage on the upper floor separated by one floor, and the sewage is discharged vertically downwards initially, sudden noise, and serious concentration areas; the suspended horizontal pipes on the lower floor are disposable The volume of sewage is large, the impact is strong, and the noise is louder, which seriously affects the life and rest of residents

In order to solve the noise problem, the PVC inner spiral silencer pipes or double-wall hollow and inner spiral silencer pipes used in the production and application of the background technology have serious design errors and defects and disadvantages. The inner spiral silencer pipes only allow a small part to be close to the sewage on the inner wall of the pipe. Flow, change the direction of the spiral drop, reduce the impact of the vertical falling sewage, but after the water flow increases, the actual inner spiral bulges, which increases the obstacles to the vertical falling water flow, the probability of impacting the pipe is higher, and the turbulent flow produces the pipe wall Vibration and noise are more, and it does not play the role of noise reduction; while the double-walled hollow tube, the cavity between the two walls, must have connecting ribs for the connecting part at intervals, and the outer wall and the inner wall are made of the same material. One piece, there are connected parts, there is no separation of the noise vibration transmission path, the path of the noise vibration transmission causes resonance, there is the root cause of the transmission noise, the pipeline also has noise in the actual use process, and there is no noise reduction effect, and it is only squeezed Process manufacturing can produce straight pipes with double-walled spiral hollow structure, while other various pipe joint parts do not have such a structure. Due to the limitation of manufacturing technology, it is impossible to manufacture various pipe joints with double-walled hollow structure, resulting in noisier than vertical tubes

In addition, the suspended horizontal sewage pipe under the roof is the vertical discharge of the upper toilet and other sewage, and the U-shaped elbow, 90-degree elbow, 45-degree tee, etc. of the suspended horizontal pipe on the lower roof have a large amount of sewage at one time. The impact force is large, the noise is louder, and there are serious defects that cannot be solved. It has no effect on eliminating noise at all, and the purpose of eliminating noise has not been achieved.

[0003] In order to eliminate the noise hazard, at present, noise-absorbing materials such as sponges are often used to wind and wrap the sewage pipes to eliminate noise. The existing problems are: the noise is not completely eliminated, and the appearance is bloated and fat; The decoration of wall inlaid tiles must be done by professional technicians. The noise reduction effect is not ideal, and the cost is high. The volume increases a lot, takes up a lot of space, and the indoor space becomes smaller; After the board is packaged, the volume increases greatly and takes up a lot of space. On top of people's heads, there is a sense of oppression and depression.

The biggest mistake and disadvantage is that the sewage pipes have to be dismantled when checking and repairing, and the building materials are all discarded, causing a lot of waste
