Abstract
The utility model relates to foam inner spiral pipe material with a hard polyvinyl chloride layer, which is composed of a cylindrical outer solid wall layer, a middle foaming layer, an inner solid layer, and elongated inner spiral ribs, wherein, each cross section of which forms a triangular. The inner side surface of the outer solid wall layer is connected with the middle foaming layer composed of a micropore foam-shaped structure, and the other surface of the middle foaming layer is connected with the outer side surface of the inner solid wall layer; the inner side surface of the inner solid wall layer is connected with every one side surface of six inner spiral ribs which are arranged in the peripheral direction of the inner solid wall layer in an equidistant and spiral mode. The structure has the functions of preventing noise and reducing water flow noise in a pipe; simultaneously, the pipe material also has the characteristic of long service life.
Description
The utility model hard PVC core layer foaming internal spiral tubing belongs to building material field.
At present, requirement according to " newly-built from now on multi-storey building must use plastic drain-pipe " of nation-building portion, people develop PVC solid wall pipe, PVC core layer foaming pipe and the real wall inner helix pipe of PVC as the indoor drainage pipe, but, they during as the indoor drainage pipe in-pipe flow noise all very big, have a strong impact on resident's physical and mental health.
The purpose of this utility model provides a kind of as the building indoor drainage pipe, reduces the good hard PVC core layer foaming internal spiral tubing of in-pipe flow noise and soundproof effect during draining widely.
The utility model hard PVC core layer foaming internal spiral tubing is to be made of outer real parietal layer, middle foaming layer, interior real parietal layer and internal spiral muscle.Outer real parietal layer, middle foaming layer and interior real parietal layer are all cylindrical, and the internal spiral muscle is the long strip that cross section is an equilateral triangle.The inner side surface of outer real parietal layer connects middle foaming layer, middle foaming layer is made up of the micropore balloon-shaped structure, the another side of middle foaming layer is connected with the outer side surface of interior real parietal layer, the inner side surface of interior real parietal layer is connected with each side of 6 internal spiral muscle, these 6 internal spiral muscle are equidistant and screw type separately on the circumferencial direction of this inner side surface is arranging, and internal spiral muscle and interior real parietal layer constitute one.
The same formula material of outer real parietal layer, interior real parietal layer and internal spiral muscle is clamp-oned composite co-extruding mould by the formula material of an extruder and middle foaming layer by another extruder and is processed into hard PVC core layer foaming internal spiral tubing.
The utility model hard PVC core layer foaming internal spiral tubing makes flowing water, and shape is mobile in the shape of a spiral continuously along the tube wall freedom, central authorities form open tubular column at tubing, make pressure reduce about 10%, ventilation capacity improves about 10 times, water displacement increases nearly 6 times, thereby reduces the in-pipe flow noise widely, and the middle foaming layer of tubing has played good soundproof effect again simultaneously, can reduce drainage noise 8-12 decibel than PVC solid wall pipe, ensure resident's physical and mental health.In addition, hard PVC core layer foaming internal spiral tubing also has in light weight, and energy consumption is low, non-environmental-pollution, the characteristics of corrosion-resistant, anti-aging and long service life.
Description of drawings:
Fig. 1 is a longitudinal profile schematic representation of the present utility model.
Fig. 2 is a horizontal section schematic representation of the present utility model.
In conjunction with Fig. 1, Fig. 2 the utility model is further described.
The utility model hard PVC core layer foaming internal spiral tubing 1 is to be made of outer real parietal layer 2, middle foaming layer 3, interior real parietal layer 4 and internal spiral muscle 5.Outer real parietal layer 2, middle foaming layer 3 and interior real parietal layer 4 are all cylindrical, and internal spiral muscle 5 is the long strip that cross section is an equilateral triangle.The thickness of outer real parietal layer 2 is 0.2mm-0.3mm, its inner side surface connects middle foaming layer 3, middle foaming layer 3 is made up of the micropore balloon-shaped structure, its thickness is 2.1mm-2.8mm, the another side of middle foaming layer 3 is connected with the outer side surface of interior real parietal layer 4, the thickness of interior real parietal layer 4 is 0.2mm-0.5mm, its inner side surface is connected with each side of 6 internal spiral muscle 5, these 6 internal spiral muscle 5 are equidistant and screw type separately and are arranging on the circumferencial direction of this inner side surface, spiral angle is 30 °-60 °, the end of the cross section equilateral triangle of internal spiral muscle 5 is long to be 2mm-5mm, height is 2mm-5mm, and internal spiral muscle 5 and interior real parietal layer 4 constitute one.
The same formula material of outer real parietal layer 2, interior real parietal layer 4 and internal spiral muscle 5 is clamp-oned composite co-extruding mould by the formula material of an extruder and middle foaming layer 3 by another extruder and is processed into hard PVC core layer foaming internal spiral tubing 1.
