Description
Technical field
Water drainage plastics tubing technical field is the utility model is related to, particularly with regard to a kind of spiral mute pipe.
Background technology
At present, domestic construction internal drainage pipeline is based on cast iron pipe, PVC, and soundproof effect is poor, PVC foamed sandwich pipes, solid wall
Or the resultant effect such as plastic pipe noise reduction such as solenoid, hollow foaming tube is undesirable.Sent when several tubing drainings
Noise is bigger, this shortcoming is especially prominent especially in skyscraper, and the life to resident family causes certain puzzlement.With building
The continuous development of industry, and the continuous embodiment that building is people-oriented are built, lifting drainpipe function reduces draining noise and seems particularly
It is important.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of spiral mute pipe multi-functional, practicality is high.
Technical problem to be solved in the utility model can be adopted the following technical scheme that to realize：
A kind of spiral mute pipe, including internal layer, intermediate layer and outer layer, it is characterised in that the internal layer and intermediate layer it
Between be provided with the first puigging；The second puigging is provided between the outer layer and intermediate layer；In the medial surface of the internal layer
On be provided with spiral stream guidance rib for sound insulation and noise reduction；Oxidation prevention layer is provided with the lateral surface of the outer layer.
In a preferred embodiment of the utility model, the internal layer and outer layer are formed using polypropylene material, middle
Layer is formed using metal damping material.
In a preferred embodiment of the utility model, first puigging, the second puigging are cellular for microvesicle
Structure.
In a preferred embodiment of the utility model, the cross section of the spiral stream guidance rib is triangular-section, institute
State spiral stream guidance rib apex angle and be both provided with circular arc chamfering, the two sides phase of the spiral stream guidance rib with the medial surface of the internal layer
Deng, water in Bottomhole pressure, using the characteristic of circular motion, make water tightly close to tube wall, achieve the purpose that sound insulation and noise reduction.
Due to the adoption of the above technical scheme, the beneficial effects of the utility model are：The utility model is simple in structure, design is closed
Reason, spiral stream guidance rib avoid water impact tube wall, have effectively organized sonic propagation, achieve the purpose that noise reduction；Using bilayer every
Sound-absorbing layer further can eliminate noise, reach mute effect.
Brief description of the drawings
Fig. 1 is a kind of structure diagram of spiral mute pipe of the utility model.
Embodiment
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
A kind of spiral mute pipe shown in Figure 1 includes internal layer 100, intermediate layer 200 and outer layer 300, internal layer 100 and outer
Layer 300 is formed using polypropylene material, and fat is environmentally protective, and tube wall is smooth, non-scaling, has excellent heat resistance and chemically-resistant corruption
Corrosion, the inside and outside layer of hard can ensure that tubing has good impact resistance while media layer damage is protected；Intermediate layer 200
Formed using metal damping material, for noise reduction.
The first puigging 400 is provided between internal layer 100 and intermediate layer 200, between outer layer 300 and intermediate layer 200
The second puigging 500 is provided with, the first puigging 400, the second puigging 500 are microvesicle honeycomb structure, and current pass through two layers
The first puigging 400, the second puigging 500 of microvesicle honeycomb structure, effectively weaken and abate the noise, reach mute mesh
's.
The spiral stream guidance rib 600 for sound insulation and noise reduction is provided with the medial surface of internal layer 100, spiral stream guidance rib 600
Cross section is triangular-section, 600 apex angle of spiral stream guidance rib and is both provided with circular arc chamfering, spiral stream guidance with the medial surface of internal layer
The two sides of rib are equal, and water using the characteristic of circular motion, makes water tightly close to tube wall, reach sound insulation drop in Bottomhole pressure
The purpose made an uproar.
Oxidation prevention layer 700 is provided with the lateral surface of outer layer 300, oxidation prevention layer 700 is evoh layer, and evoh layer can not only be to gas
Body, smell, perfume solvent etc. have an excellent blocking effect and resistance oxygen effect, but also with very high mechanical strength, elasticity,
Hardness, wearability, against weather etc. act on, and protection plastics are too early " oozing oxygen aging ".
Internal layer 100 is complex as a whole by the first adhesive linkage 800a and the first puigging 400, and the first puigging 400 passes through
Second adhesive linkage 800b is complex as a whole with intermediate layer 200, and intermediate layer 200 passes through the 3rd adhesive linkage 800c and the second puigging
500 are complex as a whole, and the second puigging 500 is complex as a whole by the 4th adhesive linkage 800d with outer layer 300；First adhesive linkage
800a, the second adhesive linkage 800b, the 3rd adhesive linkage 800c and the 4th adhesive linkage 800d are hot melt adhesive adhesive linkage, each for strengthening
The bonding strength of layer.
Staple glass fibre material can be also added in internal layer 100, the intensity of mute pipe can be increased during use.
The utility model carries out secondary noise reduction by the cooperation of spiral stream guidance rib and two soundproof layer, can greatly to greatest extent
Ground weakens or abates the noise, so as to achieve the purpose that mute；Oxidation prevention layer can not only have gas, smell, perfume solvent etc.
Excellent blocking effect and resistance oxygen effect, but also with very high mechanical strength, elasticity, hardness, wearability, against weather etc.
Effect, improves the practicality of mute pipe.
The advantages of basic principle, main feature and the utility model of the utility model has been shown and described above.One's own profession
The technical staff of industry is it should be appreciated that the present utility model is not limited to the above embodiments, described in above embodiments and description
