Abstract
The utility model relates to a drain pipe, in particular to a polypropylene silencing internally spiral drain pipe. The utility model solves the problem of low sound insulating and noise reducing effects of the conventional polypropylene silencing drain pipe. The polypropylene silencing internally spiral drain pipe comprises a polypropylene inner layer, wherein the inside surface of the polypropylene inner layer is fixed with a plurality of spiral ribs which are uniformly distributed along the axis of the inside surface. With the spiral ribs arranged on the polypropylene inner layer, the polypropylene silencing internally spiral drain pipe of the utility model effectively improves the sound-insulating and noise-reducing performance, increases the strength and rigidity of the drain pipe and has the advantages of simple structure, convenience for processing and low cost.
Description
Technical field
The utility model relates to waste pipe, is specially the quiet internal spiral waste pipe of a kind of polypropylene.
Background technique
The quiet waste pipe of polypropylene is a kind of three-decker drainage pipe, wherein internal and external layer is a polypropylene material, the mesosphere is a viscoelastic material, has certain sound insulation and decrease of noise functions, simultaneously, the quiet waste pipe chemical resistance of polypropylene, good heat resistance are widely used in fields such as office building, high-grade apartment, hospital, sanatorium, embassy, school, AAA level dwelling house, industrial building draining, blowdown.
But, detect discovery by practical application feedback and related experiment, the whole sound insulation and noise reduction effect of the quiet waste pipe of polypropylene is compared traditional cast-iron pipe system still certain gap, and generally speaking, the quiet waste pipe level of noise of polypropylene exceeds 2～10 decibels than the cast iron tube under the equal conditions.
Along with the care day by day to the environmental quality of living with people that deepens constantly of national environmental protection strategy, the existing quiet waste pipe of polypropylene can not satisfy the demand of market to the quiet waste pipe of high noise reduction, high environmental protection because the sound insulation and noise reduction effect is relatively poor.
Summary of the invention
The utility model is in order to solve the existing quiet waste pipe of polypropylene because the relatively poor problem of sound insulation and noise reduction effect provides a kind of polypropylene quiet internal spiral waste pipe.
The utility model is to adopt following technological scheme to realize: the quiet internal spiral waste pipe of polypropylene, comprise inner layer of polypropylene, and the internal surface of inner layer of polypropylene is fixed with along some screw rib of the uniform setting of its axis.Screw rib is with five equilibrium curve continuous helical decline at interval, they can increase the area of contact of current, form comparatively stable and closely knit moisture film eddy flow, the falling-threshold flow velocity of sewage is reduced to some extent, tube hub is a unobstructed air cavity, can significantly reduce the pressure surge in the quiet internal spiral waste pipe of polypropylene, improve drainage capacity significantly, improve its sound insulation and noise reduction effect when having strengthened the strength and stiffness of waste pipe.
The quantity of screw rib is 6, has further improved the sound insulation and noise reduction effect of the quiet internal spiral waste pipe of polypropylene.
The quiet internal spiral waste pipe of polypropylene described in the utility model is by setting up screw rib in inner layer of polypropylene, improved the performance of its sound insulation and noise reduction effectively, strengthen the strength and stiffness of waste pipe simultaneously, had advantage simple in structure, easy to process and that cost is low.
