Abstract

The utility model discloses a flange formula stainless steel gas hose relates to coal mine transportation technical field. The flange type stainless steel gas hose comprises a corrugated pipe, pipe sleeves are welded at two ends of the corrugated pipe, a flange is welded at one end, away from the corrugated pipe, of each pipe sleeve, and a reinforcing ring is uniformly fixedly sleeved on the outer wall of the corrugated pipe. Flange formula stainless steel gas hose, when using, the bending strength of bellows can be strengthened to the intraformational wire net of silica gel, and the beaded finish of setting can avoid the bellows pressurized deformation, has prolonged the life of bellows, and the corrosion resisting property of bellows can be strengthened to the anticorrosive coating of setting, and simultaneously, the cotton layer can make the bellows have certain inflation cushioning effect, and wear-resisting rubber layer can promote wear resistance.

Description

Flange type stainless steel gas hose

Technical Field

The utility model relates to a coal mine transportation technical field specifically is flange formula stainless steel gas hose.

Background

Coal mines are areas where humans mine coal resources in coal-rich mining areas, and are generally divided into underground coal mines and opencast coal mines. When the coal seam is far from the ground surface, a tunnel is usually dug to the underground, so that the coal is a mineworker coal mine. When the coal seam is very close to the earth surface, the coal is generally excavated by directly stripping the earth surface, which is an open pit coal mine. When the coal mine is mined, a gas hose is required to be used, generally, rubber and plastic are used as raw materials, the gas hose is easy to corrode and have poor wear resistance when being used, and meanwhile, the gas hose is bent for a long time and is easy to break, so that the requirements of users cannot be met.

SUMMERY OF THE UTILITY MODEL

To the not enough of prior art, the utility model provides a flange formula stainless steel gas hose.

In order to achieve the above purpose, the utility model discloses a following technical scheme realizes: the flange type stainless steel gas hose comprises a corrugated pipe, pipe sleeves are welded at two ends of the corrugated pipe, a flange is welded at one end, away from the corrugated pipe, of each pipe sleeve, and a reinforcing ring is uniformly fixed on the outer wall of the corrugated pipe in a fixing mode.

Preferably, the corrugated pipe comprises a silica gel layer, and an anti-corrosion coating is arranged on the inner side of the silica gel layer.

Preferably, the outside on silica gel layer is provided with cotton layer, and the outside on cotton layer is provided with wear-resisting rubber layer.

Preferably, a steel wire mesh is embedded in the silica gel layer, and the steel wire mesh is at least provided with two layers.

Preferably, the cotton layer is made of flexible cotton materials and is of a net structure.

Preferably, the wear-resistant rubber layer is made of flexible wear-resistant rubber materials, and the outer wall of the wear-resistant rubber layer is corrugated.

The utility model provides a flange formula stainless steel gas hose. The method has the following beneficial effects:

(1) this flange formula stainless steel gas hose, when using, the steel wire net in the silica gel layer can strengthen the bending strength of bellows, and the beaded finish of setting can avoid the bellows pressurized deformation, has prolonged the life of bellows.

(2) This flange formula stainless steel gas hose, the corrosion protection coating that sets up can strengthen the corrosion resisting property of bellows, and simultaneously, the cotton layer can make the bellows have certain inflation cushioning effect, and wear-resisting rubber layer can promote wear resistance.
