Problems solved by technology

[0004] Therefore, in order to further reduce the noise of running water, some PVC pipe manufacturers in my country have painstakingly studied on the basis of UPVC spiral silencer pipes, but the noise reduction effect and the quality of the pipes are not very ideal, and the set goals cannot be achieved.

Abstract

The invention discloses a UPVC (unplasticized polyvinyl chloride) hollow-wall internal spiral tube, relates to internal drainage systems of buildings, and belongs to the technical field of pipeline equipment of internal drainage systems of building materials. The UPVC hollow-wall internal spiral tube is cylindrical. Tube walls of the tube include an internal tube wall (1) and an external tube wall (2), and holes (4) are formed in positions between the internal tube wall (1) and the external tube wall (2); the internal tube wall (1) is a spiral water guide wall (5). The UPVC hollow-wall internal spiral tube has the advantages that the shortcoming of insufficient strength of a common hollow-wall tube can be overcome, the UPVC hollow-wall internal spiral tube is provided with spiral ribs and spiral veins and accordingly is high in strength and low in noise, and a good drainage effect can be realized; air tubes can be omitted when the UPVC hollow-wall internal spiral tube is applied to drainage for a high-rise building, so that spaces, materials and the mounting cost can be saved; the UPVC hollow-wall internal spiral tube is a perfect upgrading and updating product for drainage for modern buildings and is particularly applicable to drainage systems of high-rise buildings.

Description

technical field [0001] The invention relates to an internal drainage system of a building, and belongs to the technical field of internal drainage system piping equipment in building materials, in particular to a UPVC hollow-wall internal spiral pipe. Background technique [0002] UPVC pipe is made of sanitary polyvinyl chloride (PVC) resin as the main raw material, adding appropriate amount of stabilizer, lubricant, filler, color enhancer, etc., extruded by plastic extruder and injection molded by injection molding machine, after cooling and curing , shaping, inspection, packaging and other processes to complete the production of pipes and pipe fittings; its physical and chemical properties are excellent, chemical corrosion resistance, high impact strength, small fluid resistance, 30% higher flow rate than cast iron pipes of the same caliber, aging resistance, and long service life , the service life is not less than 50 years, it is an ideal material for building water supp...
