Abstract
The utility model discloses an unplasticised polyvinyl chloride (U-PVC) mute spiral noise reduction pipe which comprises an inner layer, an outer layer and a core layer. The inner layer and the outer layer are both made of U-PVC materials, a spiral rib is arranged on the inner wall of the inner layer, and the core layer is a PVC foaming layer. The U-PVC mute spiral noise reduction pipe has good mechanical performance, especially erosion resistance of the U-PVC mute spiral noise reduction pipe is remarkably better than that of an existing spiral pipe, simultaneously the U-PVC mute spiral noise reduction pipe has good effects of sound absorption, sound attenuation, sound insulation and noise reduction, mute noise reduction performance of the U-PVC mute spiral noise reduction pipe is better than that of existing similar products, and the U-PVC mute spiral noise reduction pipe is low in manufacturing cost and has wide application prospect.
Description
Technical field
The utility model relates to the plastic pipe field, specifically relates to a kind of good mechanical property that has, and has the quiet spiral noise reduction of the U-PVC pipe of good sound-deadening and noise-reducing effect simultaneously.
Background technique
Along with modernized industry and urban construction are accelerated, people's the inhabitation and the environment of work are noisy day by day, have had a strong impact on our work and rest, and high level and small sized multiple story building water vent are unexceptional.Present also release one after another some noise reductions and quiet plastic drain pipe of the plastic pipe manufacturer that has of China is like the real wall helical silencing of 2U-PVC pipe, 3U-PVC hollow wall helical silencing pipe, the quiet pipe of 4MPP etc.; But all there is more or less not part in some unsatisfactory place, and the space that haves much room for improvement is very big.Real wall helical silencing pipe of 2U-PVC and 3U-PVC hollow wall helical silencing pipe mainly carry out noise reduction through the spiral bar of its inwall, but because the spiral bar height is limited, water displacement is big; When falling rapidly, current still produce very big noise; Therefore need carry out sound insulation through additional layer, what the real wall helical silencing of 2U-PVC pipe adopted is that the U-PVC layer carries out sound insulation, and its soundproof effect is poor; Therefore, still can influence indoors artificial does, learns, has a rest.3U-PVC hollow wall helical silencing Guan Ze is that the hollow layer that between inwall and outer wall, constitutes carries out sound insulation; Its soundproof effect is superior to the real wall helical silencing of 2U-PVC pipe slightly, but in order to constitute hollow layer, is connected through several or ten several muscle between outer wall and the inwall; Other place of connecting tendon place and outer wall shrinks inconsistent during tube forming; The stress that outer wall produces at the connecting tendon place is bigger, and its physical and mechanical properties is very low, especially erosion-resisting characteristics; Connecting tendon is prone to split from root, so the mechanical property of 3U-PVC hollow wall helical silencing pipe is bad.Though its soundproof effect of the quiet pipe of 4MPP is good, receives the restriction of material property itself, all there are defective in cost, outward appearance and aging quality resistance.
U-PVC pipe remains the main pipeline in China plumbing field, is necessary to develop a kind ofly can have excellent mechanical performances, has the U-PVC pipe of fine sound-deadening and noise-reducing effect again.
Summary of the invention
The purpose of the utility model is to overcome the deficiency of existing technology, and the quiet spiral noise reduction of a kind of U-PVC pipe is provided, and the quiet spiral noise reduction of said U-PVC pipe has excellent mechanical performances, has fine sound-deadening and noise-reducing effect again.
The above-mentioned purpose of the utility model is achieved through following technological scheme:
The quiet spiral noise reduction of a kind of U-PVC pipe comprises internal layer, skin and sandwich layer; Internal layer and outer by U-PVC material formation, the inwall of said internal layer has screw rib; Said sandwich layer is the PVC foaming layer.
Internal layer mainly plays the effect of energy-eliminating noise-reducing.The screw rib of internal layer is with five equilibrium curve continuous helical decline at interval; It can increase the area of contact of current; Form comparatively stable and closely knit moisture film eddy flow, make the falling-threshold flow velocity of current reduce the air cavity of tube hub to some extent; Can significantly reduce the pressure surge in the noise reduction pipe, improve the effect of sound insulation and noise reduction to a certain extent.
Sandwich layer is the foaming layer of PVC, and PVC self is because under the effect of heat, oxygen, light, and structure changes easily, and the chlorosity that wherein contains is prone to discharge, and therefore, what mainly adopt in the plumbing field is that the U-PVC that has added plasticizing agent manages.Yet the sound insulation value of the U-PVC of hard is limited, and PVC can process the foam material of porous after adding stabilizer, have the effect of sound insulation and energy-absorbing, and because it has certain deformability, can improve the erosion-resisting characteristics of tubing.Therefore, the main effect of the sandwich layer of the utility model is sound insulation, the energy-absorbing function that utilizes the PVC material, reaches quiet simultaneously and the buffering effect.
Outer for the U-PVC layer mainly is the intensity that is used for regulating tubing, make the quiet spiral noise reduction of final U-PVC pipe have the good mechanical performance.
As a kind of preferred version, the screw rib quantity of said internal layer is preferably more than two.Many screw rib helps to improve the effect of energy-eliminating noise-reducing.
As a kind of preferred version, said internal layer, skin and sandwich layer are three-layer co-extruded shaping structure.Three's coextrusion mold, can make the layer with the layer between get in touch tightr, the assurance performance of products.
Compared with prior art, the utlity model has following beneficial effect:
The quiet spiral noise reduction of described U-PVC pipe has excellent mechanical performances, and particularly erosion-resisting characteristics obviously is superior to existing volute, has the effect of fine sound-absorbing, noise reduction, sound insulation and noise reduction simultaneously, and the performance of quiet noise reduction is superior to existing product of the same type; The preparation cost of the quiet spiral noise reduction of described U-PVC pipe is low, is with a wide range of applications.
Description of drawings
Fig. 1 is the structural representation of the quiet spiral noise reduction of the said U-PVC of the utility model pipe.
Embodiment
Below in conjunction with specific embodiment the present invention is further explained, but specific embodiment is not done any qualification to the present invention.
The structure of the quiet spiral noise reduction of the said U-PVC of present embodiment pipe is as shown in Figure 1.The structure of the quiet spiral noise reduction of said U-PVC pipe comprises internal layer 1, skin 3 and sandwich layer 2; Internal layer 1 and outer 3 constitutes by the U-PVC material, and the inwall of said internal layer 1 has screw rib, and screw rib is with five equilibrium curve continuous helical decline distribution at interval; It can increase the area of contact of current; Form comparatively stable and closely knit moisture film eddy flow, make the falling-threshold flow velocity of current reduce the air cavity of tube hub to some extent; Can significantly reduce the pressure surge in the noise reduction pipe, improve the effect of sound insulation and noise reduction to a certain extent.
Said sandwich layer 2 is the PVC foaming layer.The PVC foaming layer has the structure of porous, has the good sound insulation and the effect of energy-absorbing, and because it has certain deformability, has improved the erosion-resisting characteristics of the quiet spiral noise reduction of U-PVC pipe.
Said outer 3 are made up of the U-PVC material, and its effect is a bulk strength of regulating the quiet spiral noise reduction of U-PVC pipe.
