Abstract

The utility model discloses a corrugated hose, comprising a polyurethane sleeve and a metal wire framework, wherein the metal wire framework is of a spiral structure; and the metal wire framework is put in the polyurethane sleeve. The embodiment of the utility model adopts the polyurethane sleeve and the metal wire framework of the spiral structure; therefore, the metal wire framework of the hose can be completely put in the polyurethane sleeve; and moreover, the hose has good service life and good flow guide property; and the heat resistance and the flexibility of the hose are improved greatly.

Description

A kind of corrugated flexible hose

Technical field

The utility model relates to industry equipment liquid conveying technology field, is specifically related to a kind of corrugated flexible hose.

Background technique

Corrugated flexible hose is installed in the liquid conveying system as a kind of flexible pressure-resistant pipe fitting; In order to compensate the mutual displacement of pipeline or machine, equipment connecting end; The absorbed oscillation energy can play effects such as vibration damping, noise reduction, has multinomial characteristics such as flexible good, light weight, corrosion-resistant, antifatigue.The conventional PVC that adopts of food-grade flexible pipe is as base material on the market at present, and the structure of wire armature often exposes to the PVC base material, causes its working life, and water conservancy diversion property is bad, and the refractoriness of flexible pipe, and suppleness is barely satisfactory.

The model utility content

The utility model provides a kind of corrugated flexible hose, can address the above problem.

The utility model provides a kind of corrugated flexible hose, comprises polyurethane sleeve pipe and wire armature, and wire armature is a sped structure, and wire armature places in the polyurethane sleeve pipe.

Preferably, said wire armature and polyurethane sleeve pipe concentric.

Technique scheme can be found out; Because the utility model embodiment adopts the wire armature of polyurethane sleeve pipe and sped structure, therefore, the wire armature of flexible pipe can place in the polyurethane sleeve pipe fully; And the working life of flexible pipe; Water conservancy diversion property is all well good, the refractoriness of flexible pipe, and suppleness significantly improves.

Description of drawings

In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art; To do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below; Obviously, the accompanying drawing in describing below only is some embodiments of the utility model, for those of ordinary skills; Under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.

Fig. 1 is the sectional structure chart of corrugated flexible hose among the utility model embodiment;

Fig. 2 is the side perspective view of corrugated flexible hose among the utility model embodiment.

Embodiment

To combine the accompanying drawing among the utility model embodiment below, the technological scheme among the utility model embodiment is carried out clear, intactly description, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiments.Based on the embodiment in the utility model, those of ordinary skills are not making all other embodiments that obtained under the creative work prerequisite, all belong to the scope of the utility model protection.

Embodiment:

Like Fig. 1, shown in Figure 2, the utility model embodiment provides a kind of corrugated flexible hose, comprises polyurethane sleeve pipe 1 and wire armature 2, and wire armature 2 is a sped structure, and wire armature 2 places in the polyurethane sleeve pipe 1.Said wire armature 2 and polyurethane sleeve pipe 1 concentric.

Polyurethane is as a kind of base material, and wire armature is a spiral metal wire, and wire armature can be selected stainless steel for use; Perhaps iron wire copper facing adopts extrusion forming process that the spiral metal wire skeleton is wrapped in the polyurethane base material fully, and product cross section is a regular concentric circle; Eliminate raised or sunken on the tube wall; More smooth and easy when making fluid transfer, vibrations reduce, and simultaneously the polyurethane sleeve pipe selects for use and the spiral design of wire armature; It is bad and pliability is poor, the defective that working life is short to have solved heat resistance that existing flexible pipe exists.

More than a kind of corrugated flexible hose that the utility model embodiment is provided carried out detailed introduction; Used concrete example among this paper the principle and the mode of execution of the utility model are set forth, above embodiment's explanation just is used to help to understand the core concept of the utility model; Simultaneously, for one of ordinary skill in the art, according to the thought of the utility model, the part that on embodiment and application area, all can change, in sum, this description should not be construed as the restriction to the utility model.

Claims

1. a corrugated flexible hose is characterized in that, comprises polyurethane sleeve pipe and wire armature, and wire armature is a sped structure, and wire armature places in the polyurethane sleeve pipe.

2. a kind of corrugated flexible hose as claimed in claim 1 is characterized in that: said wire armature and polyurethane sleeve pipe concentric.
