Abstract
Double layer covered noise reducing sewer pipe and pipe fitting comprise a pipe and an outer layer and an inner body of the pipe, wherein the inner body is formed by a body and a mouthpiece which aremade of rigid plastics, and the outer layer adopts a foaming elastic soft body or flexible plastic. As the inner body is made of rigid plastic (such as raw material of rigid Unplasticized polyvinyl chloride or other rigid plastics and the like), the rigid plastic pipe wall is impact resistant, and has high wear resistant strength and long service life; and as the outer layer is made of foaming elastic flexible plastic or flexible plastic, the effect of noise reduction is good, and the manufacture is easy.
Description
Technical field
The utility model relates to sewer material for building and pipe fitting, particularly relates to a kind of double deck type and covers noise reduction formula sewer material and pipe fitting outward.
Background technique
Along with the develop rapidly of tall building, reduce the drainage pipeline draining noise, be the target of pipe production producer effort for many years.Prior art adopts soverlay technique in interlayer, hollow, microporous foam or the soft thing, obtains certain noise abatement effect.But prior art but exists the pipe fitting internal layer to intake easily, be out of shape, block, thereby causes shortcomings such as noise reduction inefficacy.
Summary of the invention
The purpose of this utility model is taked the outside-cover-type technology in order to overcome the shortcoming of existing lined technology, long service life, and the double deck type of good muffling effect covers noise reduction formula sewer material and pipe fitting outward.
The technological scheme that the utility model double deck type covers noise reduction formula sewer material and pipe fitting outward is: comprise tubing and pipe fitting skin and endosome, described endosome is that rigid plastics is made body and interface, it is characterized in that described skin is foaming elastic soft or flexible plastic.
Double deck type of the present utility model covers noise reduction formula sewer material and pipe fitting outward, described endosome is that rigid plastics (for example raw material such as hard PVC-U or other rigid plastics) is made, the rigid plastics tube wall is shock-resistant, abrasion strength resistance is high, long service life, outer is foaming elastomeric flexible plastics or flexible plastic, good muffling effect, easy to manufacture.
The utility model double deck type covers noise reduction formula sewer material and pipe fitting outward, and its described foaming elastic soft is a foam injection molding, and its described flexible plastic is injection moulding.But if tubing compound extrusion moulding synchronously then.Form the rigid plastics endosome during fabrication earlier,, make the whole connection of pipe fitting reliable then at endosome outer wall foam-injection elastomeric flexible plastics or flexible plastic.Hard outer soft compound extruding method production in tubing then adopts.

Fig. 1 is that the utility model double deck type covers noise reduction formula sewer spare elbow structure schematic representation outward;
Fig. 2 is that the utility model double deck type covers noise reduction formula sewer spare three-port structure schematic representation outward.
Fig. 3 is that the utility model covers the Silencing tube material structural representation outward.
Embodiment
The utility model relates to double deck type and covers sound insulation formula sewer material and pipe fitting outward, as shown in Figure 1 and Figure 2, comprise tubing and pipe fitting outer 1 and endosome, described endosome is that rigid plastics is made body 21 and interface 22, body can be common flat pipe pipe fitting, can be screwed fittings also, it is characterized in that described outer 1 is foaming elastic soft or flexible plastic.Described endosome is that rigid plastics (for example raw material such as hard PVC-U or other rigid plastics) is made, and the rigid plastics tube wall is shock-resistant, abrasion strength resistance is high, long service life, and outer 1 is foaming elastic soft or flexible plastic, good muffling effect is easy to manufacture.Its described foaming elastic soft is a foam injection molding.Its described flexible plastic is injection moulding.But if tubing then can adopt synchronous compound extrusion moulding.Form the rigid plastics endosome during fabrication earlier,, make the whole connection of pipe fitting reliable then at endosome outer wall foam-injection elastomeric flexible plastics or flexible plastic.Tubing then adopts compound extruding synchronously, as shown in Figure 3.Comprise foaming elastomeric flexible plastics or flexible plastic skin 1, pipe 11 in the rigid plastics, interior pipe can be common flat pipe or spiral tubing, solenoid material, hollow tubular product etc.
Claims (3)
