Abstract

The utility model discloses a fire prevention type hydraulic hose with entwined steel wires. The fire prevention type hydraulic hose with the entwined steel wires comprises a hose body and is characterized in that the hose body includes an inner rubber layer, a steel wire entwined layer, an outer rubber layer and a fire prevention layer, wherein the outer side of the inner rubber layer is covered by the steel wire entwined layer, the steel wire entwined layer is covered by the outer rubber layer, the outer rubber layer is covered by the fire prevention layer, and the surface of the fire prevention layer is provided with reinforcing ribs; the thickness of the steel wire entwined layer is 0.5-1.5mm, the thickness of the inner rubber layer is 0.5-1mm larger than that of the outer rubber layer, and the thickness of the fire prevention layer is 0.5-1.5mm. The fire prevention type hydraulic hose with the entwined steel wires has a protective function and a fire prevention function.

Description

Fire-proof steel wire-wound hydraulic flexible pipe

Technical field

The utility model relates to a kind of fire-proof steel wire-wound hydraulic flexible pipe.

Background technique

Hydraulic hose is mainly comprised of inner glue layer, steel wire floor and the outer glue-line of resistance to liquid, and inner glue layer has the fed sheet of a media of making and bears pressure, the effect that protection steel wire does not weather, and outer glue-line protection steel wire is injury-free, and steel wire floor is that framework material plays humidification.

So, hydraulic hose is mainly used in mine hydraulic support, oilfield exploitation, be suitable in engineering construction, lifting transportation, metallurgical forging and stamping, mining equiment, boats and ships, injection machine, farm machinery, various lathe and each industrial department mechanization, automatic liquid pressing system carrying having the petroleum base of certain pressure and temperature and water fluid etc. and liquid transmission use, the highest resistance to working pressure can reach 60MPa.

But current steel wire-wound hydraulic hose construction intensity Shortcomings, does not have fire protection function, haves much room for improvement!

Addressing these problems is extremely urgent as from the foregoing!

In view of this, the inventor has done deep research to this, designs a kind of fire-proof steel wire-wound hydraulic flexible pipe, has protection fire-proof function, and this case produces thus.

Model utility content

The purpose of this utility model is for a kind of fire-proof steel wire-wound hydraulic flexible pipe being provided, having protection fire-proof function.

For achieving the above object, the technical solution of the utility model is:

Fire-proof steel wire-wound hydraulic flexible pipe, comprise body, it is characterized in that: described body comprises rubber inner layer, in the outside of rubber inner layer, is coated steel wire winding layer, at the rubber-coated skin in the outside of steel wire winding layer, the thickness of described steel wire winding layer is 0.5-1.5mm, and the thickness of described rubber inner layer is greater than the thickness 0.5-1mm of rubber outer, at the coated fire protection layer of rubber outer, the thickness of described fire protection layer, at 0.5-1.5mm, is provided with stiffening rib on the surface of fire protection layer.

The beneficial effects of the utility model: the body in the utility model, it comprises rubber inner layer, in the outside of rubber inner layer, is coated steel wire winding layer, at the rubber-coated skin in the outside of steel wire winding layer, the thickness of described steel wire winding layer is 0.5-1.5mm, the thickness of described rubber inner layer is greater than the thickness 0.5-1mm of rubber outer, at the coated fire protection layer of rubber outer, the thickness of described fire protection layer, at 0.5-1.5mm, is provided with stiffening rib on the surface of fire protection layer; The setting of this structure, can play fire prevention, protection hydraulic hose.In order to strengthen the structural strength of fire protection layer, in the outside of fire protection layer, be provided with stiffening rib.

As from the foregoing, the utlity model has protection fire-proof function.

In order further to explain the technical solution of the utility model, below by specific embodiment, the utility model is elaborated.
