Abstract

The utility model belongs to the technique field of hoses, which particularly relates to a high pressure-resistant rubber-plastic spraying hose, a braid layer embedded into an inner tube and an outer tube is disposed between the inner tube and the outer tube, the braid layer adopts a plain inlaid knitted structure woven by fiber reinforcement silk, and a caking agent is disposed on the fiber reinforcement silk of the braid layer, the utility model has no phenomena of deformation, crazing, hardening, flexure breakage, leakage or other damages under different climatic conditions; the sealing value is four to five times of that of a common hose; and the technology content is increased, breakage and leakage phenomena will not take place under high pressure of 60-90MPa, and the hose does not crack and leak on trial when spraying at a height of 1,000m and from long distances of 300m, 1500m and 3000m under different climatic conditions, and is suitable for being promoted and applied in the spraying hose field.

Description

High voltage bearing rubber and plastic spraying flexible pipe

Technical field:

The utility model belongs to the technical field of flexible pipe, refers in particular to high voltage bearing rubber and plastic spraying flexible pipe.

Background technique:

PVC flexible pipe fabricating cost is low, easily processing, be widely used in the conveying of fluid at present, the spraying flexible pipe waters to irrigate as industrial or agricultural, gardens etc. and uses, because bent disconnected, the seepage of modification, be full of cracks, sclerosis can appear in the difference of weather conditions, common spraying flexible pipe or other damage phenomenon, sealing value is not high yet, under high level spraying user mode, also phenomenons such as be full of cracks, seepage can appear.

Summary of the invention:

The purpose of this utility model provide a kind of under different weather conditions not modification, do not chap, non-sclerous song is disconnected, non-leakage, the high voltage bearing rubber and plastic spraying flexible pipe of good airproof performance.

The utility model is achieved in that high voltage bearing rubber and plastic spraying flexible pipe, it is characterized in that: between interior pipe and outer tube, be provided with the braid in the pipe and outer tube in embedding, described braid is the plain weave structure that is woven into the fiber reinforcement silk, and the fiber reinforcement silk of described braid is provided with Bond.

The outstanding compared to existing technology advantage of the utility model is:

1, the utility model under different weather conditions not modification, do not chap, non-sclerous song is disconnected, non-leakage and other damage phenomenons;

2, the utility model sealing value is higher 4～5 times than conventional hoses;

3, braid of the present utility model is the plain weave structure that is woven into fiber reinforcement silk 2000D, increases tightness, improves pulsation rate;

4, scientific and technological content of the present utility model improves, and does not break under the high pressure of 60～90Mpa, and is non-leakage, under different weather conditions, 300,1500,3000 meters etc. long-range, high-rise 1000 meters sprayings are on probation does not chap, non-leakage.

Description of drawings:

Fig. 1 is interior pipe of the present utility model and braid schematic perspective view partly;

Fig. 2 is a schematic perspective view of the present utility model;

Fig. 3 is a schematic cross-section of the present utility model.

Embodiment:

With specific embodiment the utility model is further described below, referring to Fig. 1-3:

High voltage bearing rubber and plastic spraying flexible pipe, between interior pipe 10 and outer tube 30, be provided with the braid 20 in the pipe 10 and outer tube 30 in embedding, described braid 20 is the plain weave structures that are woven into the fiber reinforcement silk, and the fiber reinforcement silk of described braid 20 is provided with binder 21.

The key technical indexes of the present utility model is: internal diameter error-0.2m+1mm, the minimum value of outer external diameter of pipe 11.2mm, maximum value 12.2mm, design work pressure 5.6～7.3Mpa, minimum bursting pressure 16.8～24Mpa, bending properties modification coefficient 〉=0.8, minimum bending radius are 200mm, the utility model under different weather conditions not modification, do not chap, non-sclerous song is disconnected, non-leakage and other damage phenomenons; Sealing value is higher 4～5 times than conventional hoses; Scientific and technological content improves, and does not break under the high pressure of 60～90Mpa, and is non-leakage, under different weather conditions, 300,1500,3000 meters etc. long-range, high-rise 1000 meters sprayings are on probation does not chap, non-leakage, apply in the flexible pipe field that is adapted at spraying.

The foregoing description only is one of preferred embodiment of the present utility model; be not to limit practical range of the present utility model with this; so: all equivalences of doing according to shape of the present utility model, structure, principle change, and all should be covered by within the protection domain of the present utility model.

Claims

1, high voltage bearing rubber and plastic spraying flexible pipe, it is characterized in that: between interior pipe and outer tube, be provided with the braid in the pipe and outer tube in embedding, described braid is the plain weave structure that is woven into the fiber reinforcement silk, and the fiber reinforcement silk of described braid is provided with Bond.
