Abstract

The utility model discloses a drainage pipe, particularly a silent drainage pipe. The utility model provides a silent drainage pipe which is convenient to produce and comprises an inner pipe, an intermediate pipe and an outer pipe, wherein the intermediate pipe is made of a noise-reducing material. According to the drainage pipe, the silent drainage pipe is divided into three layers, the inner layer contacts with fluid, the intermediate layer insulates the noise, and the outer layer plays the role of protection, so that the pipe has the effect of noise insulation and has enough strength, thereby prolonging the service life; the three layers of the pipe can be produced by co-extrusion, he equipment is simple, and the operation is convenient; the noise-reducing material can be made from noise-reducing polypropylene, thereby being convenient for extrusion; both the inner pipe and the outer pipe can be made of impact-resistant propylene copolymer, thereby improving the strength of the pipe; the polypropylene can endure higher water temperature; and the intermediate pipe can be arranged into the wave shape, so that the noise is reflected repeatedly in the wall of the intermediate pipeso as to be absorbed and weakened repeatedly, thereby improving the noise reduction performance.

Description

Quiet gutter

Technical field

The utility model relates to a kind of gutter, especially a kind of quiet gutter.

Background technology

Along with improving constantly of living standard; People are also increasingly high to building human settlement's requirement, and noise pollution becomes the pollution that after air pollution, the human lives is had the greatest impact, according to statistics; The city noise strength ratio strengthened 4 times in 1956 now; And draining noise has had a strong impact on daily life as one of civilian construction main noise source, and people expect to have safe, healthy, comfortable indoor living space more.

Present gutter is generally the plastics single layer structure, will produce bigger current sound so when in use.Quiet gutter at present commonly used adopts hollow structure usually, though hollow structure has soundproof effect preferably, its intensity is lower, damages easily receiving when impacting.Section of tubing is provided with part in middle vacancy support is arranged gaining in strength, however such complex structure, difficult operation in extruding the process of production, and increased equipment cost.

The utility model content

The utility model technical problem to be solved provides a kind of quiet gutter of being convenient to produce.

The utility model solves the quiet gutter that its technical problem adopted, and comprises interior pipe, intervalve and outer tube, and said intervalve is to be processed by the absorbing sound and lowering noise material.

Further be that the absorbing sound and lowering noise material is the absorbing sound and lowering noise polypropylene.

Further be that interior pipe is processed by shock-resistant COPP.

Further be that outer tube is processed by shock-resistant COPP.

Further be the cross section undulate of intervalve.

The beneficial effect of the utility model is: quiet gutter is divided into three layers, internal layer contacting with fluid, intermediate layer sound insulation; Outer protection so both made pipeline have soundproof effect, made pipeline have enough intensity again; Thereby make improve application life; Three layers of pipeline are through co-extrusion production, and equipment is simple, and is easy to operate.The absorbing sound and lowering noise material can be used the production of absorbing sound and lowering noise polypropylene, is convenient to like this extrude, and interior pipe and outer tube all can adopt shock-resistant COPP to process, and make the intensity of pipeline increase like this, and polypropylene can bear higher water temperature.Intervalve can also be set to wavy, makes noise at middle tube wall interreflection like this, is weakened thereby absorb repeatedly, increases anti-acoustic capability.

Description of drawings

Fig. 1 is the sketch map of the utility model;

Fig. 2 is the longitudinal section sketch map of the utility model;

Component, position and numbering among the figure: outer tube 1, intervalve 2, interior pipe 3.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is described further.

As depicted in figs. 1 and 2, pipe 3, intervalve 2 and outer tube 1 in the utility model comprises, said intervalve 2 is to be processed by the absorbing sound and lowering noise material.The absorbing sound and lowering noise material can be macromolecular material or other material.When outer tube 1 and interior pipe 3 were plastics, intervalve 2 preferably used the macromolecule damping material, so just can produce through co-extrusion, and it is just comparatively convenient to produce like this, and its equipment all can adopt existing compound pipeline complex pipeline extrusion equipment.Intervalve 2 can absorbing sound and lowering noise, and interior pipe 3 can deliver fluid, and outer tube can protect impact, and therefore, the utility model can absorbing sound and lowering noise, has enough intensity again.

Concrete, the absorbing sound and lowering noise material is the absorbing sound and lowering noise polypropylene.For example with the polypropylene of barium sulfate blend, such material can absorb noise, and easy to process.And intervalve 2 receives the protection of outer tube 1 and interior pipe 3, and itself only plays the noise reduction effect, therefore can guarantee long application life.

Concrete, interior pipe 3 is processed by shock-resistant COPP.Shock-resistant COPP has superior toughness, when receiving superpower impact, can not produce the crack, even tubing is flattened, cracking also can not occur, thereby guarantee that tubing has favorable shock resistance.

Concrete, outer tube 1 is processed by shock-resistant COPP.Because in use outer tube 1 receives extraneous impact easily; And shock-resistant COPP has superior toughness, when receiving superpower impact, can not produce the crack, even tubing is flattened; Can not occur cracking yet, thereby guarantee that tubing has favorable shock resistance.

In order to increase sound absorption qualities, the cross section undulate of intervalve 2.Noise can receive the reflection of intervalve 2 when outwards propagating; Because intervalve 2 undulates; Therefore noise is the reflection of tilting, and this just makes that the propagation path of noise is elongated, and between the inclined plane of intervalve 2 interreflection; Thereby absorbed buffering repeatedly and weak by intervalve 2, thereby increased the sound absorption qualities of intervalve 2.
