Specific embodiment

Below in conjunction with the accompanying drawings, the utility model embodiment is discussed in detail.

Refering to Fig. 1 to Fig. 4, the utility model provides a kind of gas hose, using the bilayer of metal hose in outer outer tube Structure, adapts to the pressure of varying strength, and it includes elastomer connector 2, sheath 4 and the inner sleeve 3, the gold that are arranged successively from inside to outside Category flexible pipe 11 and outer tube 1, the two ends of metal hose 11 are extended to outside the outer tube 1, reduce combustion gas and the direct of outer tube 1 connects Touch, it is ensured that the corrosion resistance and raising bearing capacity of flexible pipe, the two ends of elastomer connector 2 are run through shoulder hole, and afterbody is provided with together The outer annular protrusion and annular of axle are raised, and the afterbody is exactly the one end being connected with outer tube 1, the outer annular protrusion and the inner ring Gap 21 is provided between shape projection, is easy to pipeline to be directly connected with joint, between the metal hose 11 and the inner sleeve 3 are set in this Gap 21 is interior and forms sealing, and so connection helps for combustion gas directly to flow into metal hose 11 by elastomer connector 2, in the process The part of contact is reduced, so as to the service life for extending outer tube 1 increases by one safety measure simultaneously, process is used in combustion gas Even if in metal hose 11 damage, also also outer tube 1 works on, and the sheath 4 is set in the outer wall of the outer annular protrusion, and The outer wall of outer tube 1 is extended to, locking, the protection of outer tube 1 and elastomer connector 2 is played, sheath 4 and the outer convex annular is also acted as Rise, it is bonded to each other between the outer tube 1 form sealing, increase uses safety coefficient, reduces the probability of seepage.

In order to be able to improve service life, the pressure of varying strength is adapted it to, the sheath 4 is by plastics system in the present embodiment Into cross section is dodecagon, and side wall is coated with zinc layers, and section dodecagon is favorably improved structural strength and the protection of plastics Performance, and it is zinc-plated side wall is reduced damage, the endoporus of sheath 4 is divided into equal two sections in left and right, and its length is equal to outer convex annular The length for rising, the outer tube 1 is that rubber is made, changeable use environment is met, outside the outer wall of outer tube 1, the elastomer connector 2 For gap coordinates between wall and the inwall of sheath 4, and fixed by Environment-friendlyglue glue, there is gap can just use glue, and Gap is less than or equal to 1 millimeter, contributes to mitigate the influence to periphery human and environment using Environment-friendlyglue glue, while fixed effect is powerful Effectively, outer tube 1 and the laminating of the end face of elastomer connector 2 and sealing is formed, is conducive to shutting and avoids gas leakage, the metal hose 11 It is flange-connection stainless steel metal flexible pipe, possesses preferable retractility, clog-free, lightweight, flexibility, repeated flex, corrosion resistance, resistance to The high temperatures performance such as good, its tension, lateral pressure resistant are strong in addition, are that gap coordinates with the outer tube 1, the inner sleeve 3, so make Convenient bending is reduced and damaged during, is interference fit with the elastomer connector 2, and the magnitude of interference is 0.1~0.2, improves sealing Performance, reduces the possibility oozed out of combustion gas, the inner sleeve 3 and annular projection interference fit, and its magnitude of interference is 0.05~ 0.1mm, promotes combustion gas to enter metal hose 11 by inner sleeve 3, reduces the excessive bottom for accumulating in gap 21, and the rubber connects First 2 head is connected with afterbody by chamfered transition, reduces the stress that elastomer connector 2 is produced when in use, and afterbody and outer shroud The raised external diameter ratio of shape is 17:15, its lateral wall is concordant with rear side wall to facilitate sheath 4 to be set in outer annular protrusion, makes side Wall smooth-going reduces interference, and the head outer wall of the elastomer connector 2 is provided with annulus 22, and the annulus 22 is in 2 connecting pipe of elastomer connector Sealing and locking effect are played, and the small shoulder hole of 1 millimeters deep set by the big end of shoulder hole can expand fuel gas inlet face product, make combustion gas Supply is orderly, and the bottom surface of gap 21 is provided with ring-shaped step, the ring-shaped step make the end face of inner sleeve 3 and the bottom surface of gap 21 leave away from From the bottom surface of the gap 21 and end face of metal hose 11 can directly fit makes the sealing property between metal hose 11 and elastomer connector 2 More preferably, the outer annular protrusion is identical with the internal-and external diameter of outer tube 1, facilitates the lock sealing of sheath 4.

The above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art For member, on the premise of the technology of the present invention principle is not departed from, some improvements and modifications can also be made, these improvements and modifications Also should be regarded as protection scope of the present invention.
