Abstract
It the utility model is related to a kind of noise reduction PVC drain pipe material.The tubing is made up of real parietal layer and water conservancy diversion spiral salient.The water conservancy diversion projection is circular arc, hollow structure, and arc top is provided with some holes, connects raised internal cavity and drainpipe cavity, and the hole of the raised inner side of water conservancy diversion is higher than the hole in outside.The utility model, when water-carrying capacity is big, the compressed air in pipe, it can scatter, will not occur along water conservancy diversion projection internal cavity, flow impact compressed air and the huge noise that is formed；Meanwhile internal air circulation is realized in drainpipe, current are more smoothly.
Description
Technical field
The technical field of plastic pipe is the utility model is related to, more particularly, to a kind of noise reduction PVC drain pipe.
Background technology
In recent years, PVC drain pipe is widely applied in construction drainage pipe field.With people's living standard increasingly
Improve, also more and more higher is required to the acoustic environment of residential location, the noise sent in pvc pipe drainage procedure is gradually by people
Pay attention to.At present, occur the Jing Yin tubing of real wall spiral hush pipe, hollow wall spiral hush pipe, foamed sandwich pipe etc. on the market, but
Do not still meet, the increasingly harsh inhabitation acoustic environment requirement of people.Therefore, it is highly desirable to develop a kind of more Jing Yin noise reduction
PVC drain pipe.
The content of the invention
The utility model is to overcome at least one defect described in above-mentioned prior art, there is provided a kind of noise reduction PVC drain pipe,
The drainage noise of drainpipe substantially reduces.
In order to solve the above technical problems, the technical solution adopted in the utility model is：A kind of noise reduction PVC drain pipe, wherein,
Raised including solid wall pipe and spiral stream guidance, described spiral stream guidance is raised to be located at the internal cavities of drainpipe, and is located at solid wall pipe
Inwall on.
Preferably, the spiral stream guidance projection is circular arc, hollow structure, and arc top is provided with some holes, and hole connection is led
Flow raised inner chamber and draining tube cavity.
Preferably, the spiral stream guidance projection crown height is the 0.1 ~ 0.2 of bore.
Preferably, the raised cavity height of the spiral stream guidance is the 0.4 ~ 0.6 of crown height
Preferably, described hole and the raised radial direction of water conservancy diversion form an angle, and the height at the raised inner side hole of water conservancy diversion is higher than outer
The height at side hole.
Preferably, the drainpipe includes following components：Polyvinyl chloride resin（SG-5）100 parts；0.1 ~ 3 part of lubricant；Calcium zinc is steady
Determine 1 ~ 5 part of agent；0.1 ~ 3 part of coupling agent；100 ~ 150 parts of vermiculite, 100 ~ 150 parts of barium sulfate.
Conventional noise reduction PVC drain pipe material, although having spiral stream guidance muscle, current can flow down along fuisw rib, so as to subtract
Few current noise to caused by the impact of pipe material inner wall.But when water-carrying capacity is larger, current flowing can cause the quick of air
Compression, current and air-flow, which bump against to hit, triggers bigger noise.The utility model, hollow structure is set in water conservancy diversion projection, and connected
Drainpipe.When current are swept away, inner air tube can scatter along the space in water conservancy diversion projection, will not be compressed and cause to hit generation
Noise.Moreover, the air circulation in tubing, can make tubing draining current more smoothly.The inclination of hole, is not easy into current
Water conservancy diversion projection cavity.In addition, the filling of vermiculite and barium sulfate, the surface density of material, sound insulation property enhancing are improved.
Compared with prior art, beneficial effect is：The utility model sets hollow structure in spiral stream guidance projection, and water conservancy diversion is convex
Starting the arc top sets hole, and the noise of the shock of air compression, current and air-flow, realizes drainpipe caused by avoiding a large amount of current
Interior internal air circulation, the drainage noise of drainpipe substantially reduce.

Fig. 2 is the raised structural representation of the utility model spiral stream guidance.
Fig. 3 is the utility model spiral stream guidance projection cross-sectional view.
Embodiment
Accompanying drawing being given for example only property explanation, it is impossible to be interpreted as the limitation to this patent；It is attached in order to more preferably illustrate the present embodiment
Scheme some parts to have omission, zoom in or out, do not represent the size of actual product；To those skilled in the art,
Some known features and its explanation may be omitted and will be understood by accompanying drawing.Being given for example only property of position relationship described in accompanying drawing
Explanation, it is impossible to be interpreted as the limitation to this patent.
Fig. 1 is a kind of structural representation for noise reduction PVC drain pipe material that the present embodiment provides, as shown in figure 1, the noise reduction
PVC drain pipe material include real wall outer layer 1 and spiral stream guidance projection 2, the raised height of water conservancy diversion is the 0.1 of bore, and water conservancy diversion is convex
Play 0.5 that cavity height is water conservancy diversion height of projection.As shown in Figure 2,3, spiral stream guidance is raised, and arc top is provided with some holes, hole
Hole and raised radially into 30 DEG C of angles with water conservancy diversion so that the height at hole is higher than outside hole on the inside of water conservancy diversion projection cavity.
Noise reduction PVC drain pipe described in the present embodiment includes following components：Polyvinyl chloride resin（SG-5）100 parts；2 parts of lubricant；Calcium
3 parts of zinc stabilizer；2 parts of coupling agent；120 parts of vermiculite, 130 parts of barium sulfate.
The utility model, hollow structure, and communicated drainage pipe are set in water conservancy diversion projection.When current are swept away, inner air tube meeting
Space in water conservancy diversion projection is scattered, and will not be compressed, and is caused to hit and produced noise.Moreover, the air circulation in tubing,
Tubing draining current can be made more smoothly.The inclination of hole, current are made to be not easy into water conservancy diversion projection cavity.In addition, vermiculite and sulphur
The filling of sour barium, improve the surface density of material, sound insulation property enhancing.
Obviously, above-described embodiment of the present utility model is only intended to clearly illustrate the utility model example, and
It is not the restriction to embodiment of the present utility model.For those of ordinary skill in the field, in described above
On the basis of can also make other changes in different forms.There is no need and unable to give all embodiments
It is exhaustive.All made within spirit of the present utility model and principle all any modification, equivalent and improvement etc., should be included in
Within the protection domain of the utility model claims.
