    The invention relates to mechanical engineering and can be used to transport gases and gas-containing liquids by high-pressure hoses.
    The purpose of the invention is to increase the reliability of a multi-layered hose by using a double safety system, in which the hose wall contains one or more gas discharge layers.
    FIG. 1 shows a multilayer hose, a slit; in fig. 2 - the same, with the depicted connecting piece; in fig. 3 - embodiment of a multi-layer hose, a slit; in fig. 4 - the same, with the depicted connecting part; in fig. Figures 5 and 6 show the variants of the implementation of the multilayer hose with channels and gas discharge layers, a slit.
    A multilayer hose (Fig. 1 consists of an internal support element in the form of a flexible pipe 1, made of metal or synthetic material .. The flexible pipe 1 is covered by a protective textile layer 2, above which the internal sealing layer 3, in turn, is made of a flexible, chemical-resistant plastomer or plastomer. Layer 3 is covered by layer 4. of rubber, which also separates the pads 5 of the absorbing layer 6. The latter is covered with a fabric frame 7 and a layer of rubber 8 that protects the slit nga from external influences. The flexible pipe 1 prevents the formation of bubbles, which are diffused from the transported medium. The inner layer 3 provides impermeability to the transported gas and liquid. Since the layer 3 is placed between the pipe 1 and layer 4, which has a slight stretching, their volume should not change due to swelling, therefore the sealing layer 3 should not swell under the action of the medium flowing through the hose. In case of swelling above 10% of the bend, the pipe 1 may break. At the temperature of manufacture, the protective textile layer 2 prevents the layer 3 from entering the cavity of the flexible pipe 1. The layer 4 separating the reinforcement linings 5 eliminates friction when bending e. The gaskets 5 can be used

    yawn dp gas vent, as they have a cable structure, and their cross section is not filled with the material of layer 4 at pressure during the vulcanization. The gaskets 5 are most preferably made of steel cable having a strength sufficient to absorb the internal pressure in the hose.
    The multilayer hose in FIG. 2 comprises a connecting part 9, the connection between the reinforcing layer 6 and the connecting part 9 being produced by means of an adhesive layer .10. The cavities of the gaskets 5 of the reinforcement layer 6 are in communication with the gas collecting chamber 11, made in the connecting piece 9. The gas collection layer of the chamber 11 can be made of gray fabric or of non-rubberized steel cord. The gas entering chamber P through the cavities of the gaskets 5 is removed from chamber 11 through a check valve 12 installed in the gas outlet 13 and made, for example, in the form of a 0-ring on the outer surface of the hectare. The multi-layered hose is provided with a conical bushing 14 placed between the inner layer 3 and the reinforcing layer 6. In FIG. Figure 3 shows the embodiment of a multi-layer hose that is resistant to both internal pressure and axial tensile forces. Resistance to tensile forces is provided by means of spiral pads 15, and to internal pressure by means of pads 5 of reinforcing layer 6. Venting The connecting layer 16 is formed over the inner layer 3, which does not allow gas and liquid to pass through, and consists of a non-rubberized, hard or cord fabric with a loose, friable structure. Gas is directed through this structure to port 13 or. to connecting part 9 (not shown in Fig. 3). Through the use of the vapor layer 16, a so-called pipe structure in the pipe is created. This design allows to obtain a flexible pipe consisting of two parts not interconnected by a clutch, the lower part being formed by the inner flexible pipe layer 3, and the upper part consists of the remaining structural elements. The gas discharge layer can also be made of steel cord, the internal cavities of which are not filled with sealing rubber to ensure gas conduction. In this case, the structure of the pipe in the pipe does not take place, because the connection of the steel cord with its surrounding layers of rubber is produced by adhesion.
    The multilayer hose in FIG. And has a connecting part 9 and a spiral gasket 15, made of resin-impregnated fiberglass. In this case, the gases are also removed through the check valve I2, which prevents the external environment, such as sea water, from penetrating into the cavity of the hose.

    a drilled metal ring 17,20 and gas release layers directed to the multilayer hose in FIG. 5 between the reinforcing layer 6 or the gas discharge layer 16 and the outer surface of the pshang there is an additional gas collecting and exhaust layer 18, through which collecting can be discharged gases. For this purpose, non-rubberized textile cord with a loose structure or steel cord, directed in the transverse direction through separate pads 5, are used. To prevent penetration of the external environment (i.e., sea water), said cords or textile fabrics are impregnated with a water-repellent material.

    The gases accumulating in the cable structure are collected in a thin porous layer 19, filled in the form of a non-rubberized textile ring, and discharged through the discharge layer .18 disposed in a beveled position. Thin layer 19 can also be produced on non-rubberized fabric. serve in the oblique direction of drilling, holes and check valves, closing under the action of external pressure and otkryvshayas from the creating internal pressure,
