Abstract

The present invention relates to sewer pipe for building, and is especially silencing sewer pipe with soft inner layer. The silencing sewer pipe includes one outer layer of hard material and one inner layer of soft material, and the soft material can reduce the impact of water to pipe wall, reduce shock and silence. The silencing sewer pipe with soft inner layer may be used widely in buildings.

Description

Damping, silencing water drain pipe with soft inner layer

Technical field

The present invention relates to a kind of pipe for building, be specifically related to sewer.

Background technique

Present plastics sewer for building, because it is corrosion-resistant, light weight, advantages such as easy plasticity is good are widely applied to building field, along with applying of this sewer, new problem attracts much attention again, in order to solve the noise reduction problem of plastics sewer, people have found out thousand and one way, patent ZL97210499.2 for example: the sewer that has the internal spiral rib, utilization is provided with the scroll of several water conservancy diversion in the inboard of tube wall, can make water when dirty, form eddy flow along described several scrolls, and then reduce, but erasure effect not fine owing to current fling the noise that produces; Patent ZL99212628.2: the plastic tube of the internal spiral rib of band stiffening rib in the hollow wall, it is the form that on the basis of patent ZL97210499.2, the tube wall of sewer is changed into hollow and have stiffening rib, the tube wall of hollow belt stiffening rib not only can play the effect that strengthens sewer intensity, the effect that also has sound-absorbing, erasure effect than patent ZL97210499.2 is better, but still can not thoroughly eliminate because the noise that the water slug tube wall produces.

Summary of the invention

In order to solve the problem of sewer noise reduction further, alleviate the vibrations of sewer, improve sewer erasure effect, the present invention has designed a kind of damping, silencing water drain pipe with soft inner layer.

Damping, silencing water drain pipe with soft inner layer comprise hard layer tube wall and soft layer tube wall, the hard layer tube wall is to be made by hard material, the soft layer tube wall is to be made by soft material, the soft layer tube wall is fixed on hard layer tube wall inboard, the some scrolls of being made by soft material are arranged on the inwall of described soft layer tube wall, and described some scrolls and described soft layer tube wall become one.

The present invention is that the tube wall with sewer is made into to be made up of the hard material layer in the outside and the soft material layer of internal layer by original hard material, and increased the scroll of making by soft material in the tube wall inboard, the soft material layer can be alleviated the impact force of water to tube wall, scroll makes water trickle along scroll downwards by the effect of its water conservancy diversion, played the effect of damping, noise reduction effectively.

Description of drawings

Fig. 1 is the structural representation of the specific embodiment of the present invention one, Fig. 2 is the plan view of Fig. 1, Fig. 3 is embodiment two structural representations, Fig. 4 is the plan view of Fig. 3, Fig. 5 is embodiment three structural representations, Fig. 6 is the plan view of Fig. 5, and Fig. 7, Fig. 8, Fig. 9 are the structural representations of embodiment four.

Embodiment

Embodiment one: referring to Fig. 1, Fig. 2, the damping with soft inner layer of present embodiment, silencing water drain pipe are made up of hard layer tube wall 1 and soft layer tube wall 2, hard layer tube wall 1 is to be made by hard material, soft layer tube wall 2 is to be made by soft material, and soft layer tube wall 2 is fixed on hard layer tube wall 1 inboard.

Embodiment two: referring to Fig. 3, Fig. 4, the damping with soft inner layer of present embodiment, silencing water drain pipe also comprise some scrolls of root 3, described some scrolls 3 are to be made by hard material, it is fixed between hard layer tube wall 1 and the soft layer tube wall 2, becomes one with hard layer tube wall 1.

The some scrolls 3 that present embodiment increases play the effect of water conservancy diversion, noise reduction.

Embodiment three: referring to Fig. 5, Fig. 6, the difference of the damping with soft inner layer of present embodiment, silencing water drain pipe and embodiment two is, described some scrolls 3 are to be made by soft material, it is fixed on soft layer tube wall 2 inwalls, and becomes one with soft layer tube wall 2.

The difference of present embodiment and embodiment two is that some scrolls 3 are to be made by soft material, and damping effect is better, and then erasure effect is also better.

Embodiment four: referring to Fig. 7 to Fig. 9, the difference of the damping with soft inner layer of present embodiment, silencing water drain pipe and embodiment one to three arbitrary mode of execution is, it also comprises hard outer wall 4 and stiffening rib 5, hard outer wall 4 and stiffening rib 5 all are to be made by hard material, hard outer wall 4 is enclosed within hard layer tube wall 1 outside, between hard outer wall 4 and hard layer tube wall 1, be fixed with stiffening rib 5.

Hard outer wall 4 and stiffening rib 5 have been increased in the present embodiment, make between hard outer wall 4 and the hard layer tube wall 1 air clearance is arranged, can play the effect of sound insulation, erasure effect is more obvious, stiffening rib 5 between hard outer wall 4 and the hard layer tube wall 1 plays the effect that strengthens tube wall strength.
