Abstract
The utility model discloses a double-ply drainage accordion pipe consisting of a pipe body and an upper interface. The pipe body comprises an inner pipe and an outer pipe and the inner pipe and the outer pipe are connected as a whole by high-temperature and high-pressure blow molding of precise mould. Ripples are arranged on the pipe body. The inner layer and outer layer are completely combined as a whole without any air bubble and gap in the faying face. The material of the outer layer is ordinary extrusion plastic (EVA or PE) and the material of the inner layer is PE or EVA improved by special industrial art. The utility model has the advantages of high-duty'good flexibility, bending endurance, corrosion prevention, shock resistance, ageing resistance, no blemishes, and local breach resistance. The utility model is suitable of different climate environment.
Description
Technical field
The utility model relates to a kind of waste pipe, especially a kind of double-layer drainage bellows.
Background technique
Present washing machine, air-conditioning, refrigerator and dishwasher are used advances, bellows drainpipe all is single layer structure, cause defectives such as trachoma, Mao Dong, partial fracture and bulging easily, thereby cause the water pipe seepage, and singel-ply bellows all has tangible deficiency at aspects such as anti-bending, shock-resistant, ageing-resistant, leakage proofs, can't adapt to various climatic environment.
Summary of the invention
The purpose of this utility model provide a kind of rational in infrastructure, intensity is high, good toughness, anti-bending, impact-resistant double-layer drainage bellows, it has overcome the deficiency that prior art exists.
The purpose of this utility model is achieved in that it includes body and last interface, and described body comprises pipe in an outer tube and, and described outer tube and interior pipe are bonded into one by precision die high temperature blowing high pressure, and described body is provided with ripple.
Described outer tube is made by common PE or EVA material, and interior pipe is made by the PE or the EVA material of modification.
Because the utility model has adopted said structure, compared with prior art have the following advantages: the utility model internal and external layer junction plane does not have bubble, voidlessness, combines together fully; Cladding material is common extruding with plastics (EVA, PE), inner layer material is with PE or EVA through the special process modification, intensity height, good toughness, anti-bending, corrosion-resistant, shock resistance, anti-aging, no trachoma, difficult local are broken, applicable to various climatic environment.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is a structural representation of the present utility model;
Embodiment
As shown in the figure, of the present utility modelly advance, bellows drainpipe includes body 4 and last interface, body 4 comprises pipe 2 in an outer tube 1 and, outer tube 1 and interior pipe 2 by two kinds of materials through two kinds of high speed mixing extruders, two kinds of materials of inner and outer pipes are extruded double-deck material embryo by co-extrusion die head high temperature, high pressure, it is adhesion-molded to pass through precision die high temperature blowing high pressure again, and the internal and external layer junction plane does not have bubble, voidlessness, combines together fully.On body 4, be provided with ripple 3, thereby make of the present utility modelly to advance, the anti-bending of bellows drainpipe, shock resistance significantly strengthen.Its middle external tube 1 is made by common extruding with plastics (EVA, PE), and interior pipe 2 usefulness are made through the PE or the EVA material of special process modification.Double-deck inlet pipe, drain pipe can be widely used in household electric appliance industries such as washing machine, air-conditioning, refrigerator and dishwasher.
