Abstract

The utility model discloses a sound-proof drain pipe, comprising a main pipe, a three-way pipe, an elbow pipe and a connecting short pipe. The utility model is an improvement of current common drain (pollution discharge) pipe. A sound-proof layer is disposed outside the drain (pollution discharge) pipe; and a layer of outer pipe is provided on the sound-proof layer; wherein the main pipe, the three-way pipe, the elbow pipe and the connecting short pipe are respectively composed of an inner layer pipe, a sound-proof layer and an outer layer pipe. The inner layer pipe and the outer layer pipe are preferably made of PVC material, which is beneficial to anti-corrosion and anti-aging. The sound-proof layer is preferably made of polyurethane foam material; the thickness of the sound-proof layer is 15-40% of the diameter of the inner layer pipe, so as to ensure the sound-proof and insulating effect. The utility model has simple structure, low production cost, good sound-proof and insulating effect, which can effectively avoid the noise pollution caused by water discharge (pollution discharge); and the utility model can be easily applied and promoted, so as to replace the common drain (pollution discharge) pipe which is commonly used in multi-floor, high-rise residential or office buildings.

Description

A kind of sound insulation waste pipe

Technical field

The utility model belongs to building material field, is specifically related to the improvement of a kind of draining (or blowdown) pipe, particularly a kind of sound insulation draining (or blowdown) pipe.

Background technique

Draining (or blowdown) in buildings such as multilayer, high residential building or office building is at present managed, and great majority are individual layer U-PVC pipes, and its sound insulation and heat insulation effect are poor.Draining (or blowdown) pipe that some expose outside wall can send the singing of the stream that gurgles when draining (or blowdown).The noise that this draining (or blowdown) is sent brings very big influence to the rest of resident family.Notice of authorization number has just been announced a kind of novel sound insulation water pipe for the Chinese utility model patent of CN2867035Y, and it is with present running water pipe or blowdown plastic tube, between pipe outer wall and inner tube wall, increases one deck vacuum layer, to reach the purpose of sound insulation.But above-mentioned sound insulation water pipe, complex manufacturing technology, manufacture cost is higher.

Summary of the invention

For overcoming the technological deficiency that existing draining (or blowdown) pipe exists, the utility model provides a kind of draining (or blowdown) simple in structure, cheap for manufacturing cost, that soundproof effect is good to manage.

For realizing above-mentioned purpose, the utility model solves the technological scheme that its technical problem adopted and is: a kind of sound insulation draining (or blowdown) pipe comprises the person in charge, three-way pipe, bend pipe and is connected short tube.The said person in charge, three-way pipe, bend pipe and be connected short tube and be made up of inner tube, puigging and external pipe respectively, such being designed with is beneficial to sound insulation, insulation.Said three-way pipe, bend pipe and be connected the external diameter that the internal diameter of short tube is larger than respectively or equals to be responsible for are convenient to be responsible for three-way pipe, bend pipe and are connected the connection of short tube.The preferred PVC material of said inner tube and external pipe helps anticorrosive, anti-aging.The preferred foamed polyurethane material of said puigging; Puigging thickness is between the 15%-40% of inner tube diameter.Such design guarantees sound insulation, heat preservation effect.When laying draining (or blowdown) pipeline, can select for use with being responsible for three-way pipe, the bend pipe that matches or being connected short tube according to the concrete condition of pipeline to connect.The person in charge and three-way pipe, bend pipe and be connected the joint of short tube with PVC glue special gummed, guarantee that it is connected firmly, easy construction.The utility model is simple in structure, cheap for manufacturing cost, sound insulation and high insulating effect; Can effectively prevent the noise pollution that draining (or blowdown) is produced; And implement easily to promote, substitute normal discharge (or blowdown) pipe that in buildings such as multilayer, high residential building or office building, generally uses at present.

Embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is described further, like Fig. 1, shown in Figure 2, a kind of sound insulation draining (or blowdown) pipe comprises the person in charge [1], three-way pipe [2], bend pipe [6] and is connected short tube [7].The said person in charge [1], three-way pipe [2], bend pipe [6] and be connected short tube [7] and form by inner tube [3], puigging [4] and external pipe [5] respectively.Said three-way pipe [2], bend pipe [6] and the internal diameter that is connected short tube [7] are larger than or equal to be responsible for the external diameter of [1] respectively, are convenient to be responsible for [1] and three-way pipe [2], bend pipe [6] and the connection that is connected short tube [7].The preferred PVC material of said inner tube [3] and external pipe [5] helps anticorrosive, anti-aging.In order to guarantee soundproof effect, the preferred foamed polyurethane material of said puigging [4]; Puigging [4] thickness is between the 15%-40% of inner tube [3] diameter.When laying draining (or blowdown) pipeline, can select for use with being responsible for three-way pipe [2], the bend pipe [6] that [1] match or being connected short tube [7] according to the concrete condition of pipeline to connect.In order to guarantee sound insulation draining (or blowdown) pipeline, be connected firmly, easy construction, be responsible for [1] and three-way pipe [2], bend pipe [6] and the joint that is connected short tube [7], glue together with the PVC glue special.

Claims
