Description

A kind of sound insulation and noise reduction drainpipe

Technical field

The utility model relates to building pipe technical fields, and in particular to a kind of sound insulation and noise reduction drainpipe.

Background technique

Noise is the key factor for influencing people's living environment health, with advances in technology with people to living environment It is continuously improved, the improvement for building noise also increasingly attracts people's attention.In construction drainage engineering in recent years, with general Logical drain cast iron pipe road is eliminated, and UPVC plastic drain-pipe is widely used under construction, although the tubing advantage It is more, it is exactly that soundproof effect is poor there is also very big disadvantage, sewage, which washes away tube wall, can generate very big noise, serious shadow Ring the normal life for having arrived people.And currently used drainpipe is typically all to add one layer of sound-proof material in outer tube layer to make an uproar to reduce Sound, but the service life of sound-proof material is not long, once and fluid seepage enter after sound insulation cotton layer, will seriously affect Its sound-absorbing effect, and sound-proof material dampness concentration also can the structure material to tubing affect, to influence tubing Service life.

Utility model content

That in view of the above problems, the object of the present invention is to provide a kind of sound insulation and noise reduction effects is good, pipe structure intensity is high, The sound insulation and noise reduction drainpipe of corrosion-resistant thermal insulation.

To achieve the above objectives, the present invention adopts the following technical solutions:

A kind of sound insulation and noise reduction drainpipe, including drain body, the drain body include inner core, outer wall and inner core Middle layer between outer wall, middle layer are the particle sound absorbing layer, puigging and tubing enhancement layer being successively bonded from inside to outside, The tubing enhancement layer and outer wall molding are integrally formed；Multiple convex sets, each convex sets are equipped with inside the drain body Including four protrusions, four protrusions are distributed in the same plane and uniformly on the inner wall of drain body, multiple convex sets It is distributed in inside entire drain body along drainpipe length direction.

Particle in the particle sound absorbing layer is polyvinyl chloride spherical shape particle.

The inside of the polyvinyl chloride spherical shape particle is cavity structure.

Diamond shape sound insulation chamber is equipped in the puigging.

The tubing enhancement layer is thermosetting fibre enhancement layer, and wherein fiber is continuous fiber braided fabric.

The material of the inner core and outer wall is polyvinyl chloride.

The outer layer of the outer wall is additionally provided with insulating layer, is equipped with erosion resistant coating outside insulating layer.

The utility model is designed as inside and outside double-layer tube wall compared with prior art, by drainpipe, and sets between There are particle sound absorbing layer and the puigging equipped with diamond shape sound insulation chamber, honeycomb structure is integrally formed in the sound absorbing layer of particle composition, can Effectively to absorb the noise of water flow generation, while the diamond shape sound insulation chamber in puigging further makes the sound passed out not Disconnected Circulated reflection effectively avoids the noise that flowing water generates in pipeline and is spread out of by pipeline, reduced to reduce intensity of sound Noise pollution；And ceramic particle has stronger service life compared with the sound-proof material of the prior art；It is molded in inside outer wall It is integrally formed Guan Youcai enhancement layer, the structural strength and stress intensity of tubing is enhanced, extends the service life of drainpipe.Together When, convex sets are set on the inner wall of drainpipe, reduce the channel diameter of water flow, thus make the water flow to flow downward every one section just It flows at thread, then spreads apart again, can be reduced in drainpipe to avoid the disconnection of circulating water stream and the presence of inner air The noise that portion's water flow friction or turbulence are formed.

Detailed description of the invention

Fig. 1 is the structural schematic diagram of the utility model drainpipe；

Fig. 2 is the diagrammatic cross-section in Fig. 1 along the direction A-A.

Specific embodiment

To more fully understand those skilled in the art to the utility model, With reference to embodiment to this reality It is described further with novel:

As depicted in figs. 1 and 2, a kind of sound insulation and noise reduction drainpipe, including drain body 1, the drain body 1 include Middle layer between inner core 16, outer wall 18 and inner core 16 and outer wall 18, middle layer are that the particle being successively bonded from inside to outside is inhaled Sound-absorbing layer 17, puigging 14 and tubing enhancement layer 13, the tubing enhancement layer 13 are integrally formed with the molding of outer wall 18；The draining Multiple convex sets are equipped with inside tube body 1, each convex sets include four protrusions 2, and four protrusions are in the same plane and uniformly Be distributed on the inner wall of drain body 1, multiple convex sets are distributed in entire drain body along drainpipe length direction Portion.

Particle in particle sound absorbing layer 17 is polyvinyl chloride spherical shape particle, using the more existing acoustical cotton of polyvinyl chloride material With better anti-corrosion waterproof effect, even if nor affecting on the sound-absorbing effect in later period, while to pipe there are slight leakage scenarios The structural strength of material does not also influence；And honeycomb structure is integrally formed in spheric granules, more conducively to the absorption of noise.

The inside of polyvinyl chloride spherical shape particle is cavity structure, makes the pipe prepared while guaranteeing absorbing sound and lowering noise effect Material is lighter.

Diamond shape sound insulation chamber 15 is equipped in puigging 14, diamond shape sound insulation chamber can make sound not when sound is transferred to puigging The Circulated reflection interrupted effectively weakens the noise transmitted outward to reduce its intensity.

The inner core 16 and outer wall are polyvinyl chloride material, and there is polyvinyl chloride material light-weight, corrosion-resistant, water flow to hinder The advantages that power is small, energy saving, low cost.

Tubing enhancement layer 13 is thermosetting fibre enhancement layer, and wherein fiber is continuous fiber braided fabric, and continuous fiber is compiled Fabric and the outer wall of polyvinyl chloride material, which are molded, to be integrally formed, and can effectively be enhanced the structural strength of tubing, effectively be avoided pipe Material unbalance stress damages, and extends the service life of tubing.

Since the resistance to jelly and heat resistance of polychloroethylene pipes are all poor, insulating layer 12 is additionally provided on the outside of outer wall, Erosion resistant coating 11 is set outside insulating layer 12, and further insulating layer is protected.
