Description
Technical field
The utility model relates to a kind of high-pressure metal flexible pipe.
Background technique
But metallic hose is widely used in machinery, chemical industry, aviation, shipbuilding and building field because of having free bend, performance such as ageing-resistant and corrosion-resistant.
Metallic hose commonly used at present, usually form by structures such as metal bellows added metal nets, as Chinese utility application number 200920241411.4 disclosed a kind of " High Temperature High Pressure metallic hoses ", comprise and taking over and metal bellows, the outside winding steel wire of described metal bellows, the steel wire outside is with one or more layers metal net.China's utility application number 03256827.4 disclosed a kind of " a kind of high-pressure metal flexible pipe " comprises that an end of joint core is equipped with nut, and the other end connects bellows and net.China's utility application number 03263791.8 disclosed a kind of " High Temperature High Pressure metallic hose " comprises and takes over high pressure flange and the encryption bellows that two ends connect respectively that the metal net is coated on the skin of bellows and takes over.Chinese invention patent number 200310103472.1 disclosed a kind of " a kind of metallic hoses of conveyance fluid ", comprise metal bellow and at the metallic hose net of metal bellow outside suit, two end connectors connect, and are with the metal protection pipe of fixedlying connected with joint in the outside of metallic hose net.This metal protection pipe is the metal bellows that material, waveform are not limit.
China's utility model patent numbers 96231432.3 discloses a kind of " the scalable metallic hose of sealed type ", on a kind of connecting pipe that is used to be arranged between motor and outlet pipe, have sealing function, outer surface is rounded, scalable metallic hose, comprise circle circle a coupling ring that is coupled to each other and a flange that is positioned at the flexible pipe two ends, after being coupled to each other of coupling ring, its inner passage that constitutes near sealing state, the profile of coupling ring is rounded, and external series gap that is positioned at the outside and the internal clearance that is positioned at inside are arranged between each coupling ring.In this invention, after being coupled to each other of coupling ring, its inside can only constitute the passage near sealing state, because special seal arrangement is not set, can not guarantee sealing fully, therefore this metallic hose can satisfy the usage requirement of discharging engine exhaust, but can not be used for the conveying of the higher pressurized gas of highly pressurised liquid or seal request.
China's utility model patent number 02217162.2 discloses a kind of " metal spiral sleeve pipe ", it comprises a plurality of tube couplings, each tube coupling is to form with the continuous coiling in a spiral inclination angle with continuous strip of metal, each tube coupling all is ∽ shape on the longitudinal section, comprise a first surface, one and the second surface that staggers of first surface, from the following hook of first surface bending downwards and from second surface rising to the bait of bending upwards, the following hook of adjacent two tube couplings and rising to the bait fastens mutually and forms the metal sleeve of spiral extension.This metal spiral sleeve pipe can be widely used in the protection of spools such as electric wire, cable or flexible pipe.But do not consider sealing problem, and because rise to the bait and the mutual fastening of following hook do not take into full account metal sleeve axially with radially strength problem, can not be used for the conveying of highly pressurised liquid.
Summary of the invention
In order to overcome the shortcoming that the structural strength that has the metallic hose existence now is not high and be unfavorable for carrying high-pressure liquid, the utility model provides a kind of high-pressure metal flexible pipe.
The technical solution adopted in the utility model is:
A kind of high-pressure metal flexible pipe, it is characterized in that: comprise mutual sleeve pipe of metal and elastic protective layer, described elastic protective layer is located at the outside of the mutual sleeve pipe of described metal, and the mutual sleeve pipe of described metal is formed with the continuous coiling of a helix angle by continuous metal tape, and the longitudinal section of described metal tape is class S shape; One end in described longitudinal section is provided with first hook, its the other end is provided with second hook, on described first hook first rotating part is arranged, and on described first rotating part first insertion part is arranged, on described second hook second rotating part is arranged, on described second rotating part second insertion part is arranged; Described second rotating part is inserted, pushes against in first hook on the described metal tape and the mutual fit fastening of second hook on the adjacent metal band, described first insertion part, and described first rotating part is inserted, pushed against in described second insertion part; Described first insertion part or second insertion part have been provided with the heaving of the sea of buffering metamorphosis.
Further, the connection part of described first hook and second hook is skewed.
Further, the afterbody of described first hook and second hook is equipped with the firm circle of fastening and returns hook structure.
Further, described metal tube is a circular hollow tube.
Further, described elastic protective layer is the circular hollow tube of wave-like type for outer tube wall.
Further, described elastic protective layer adopts the high resilience material to make.
The mutual sleeve pipe of metal described in the utility model can adopt stainless steel belt or Galvanized Steel Strip, corrosion resistance and good.
Elastic protective layer described in the utility model adopts the high resilience material, and section configuration is wave-like type, has guaranteed wear-resisting, the anti-bending strength of metallic hose, and has further improved the bearing capacity of metallic hose.
The beneficial effects of the utility model are embodied in: simple in structure, bearing capacity is strong, the pressure loss is little and satisfy high pressure, seal request, can be used for carrying high-pressure liquid.
