Description
Technical field
The present invention relates to a kind of fuel gas supply conduit, relate in particular to a kind of engine gas supply line.
Background technique
Rock gas is as a kind of Novel clean performance source, in whole world extensive use, the motor that the rock gas of take is fuel also will be widely used, offshore production platform generally all adopts take the duel fuel engine that rock gas and oil be raw material, if motor is not taked to certain protective measures, can cause whole cabin to become deathtrap, and then engine room facilities just need to have requirement of explosion proof, greatly improve the cost of device.How to guarantee rock gas do not reveal or reveal rear controlled and reveal after how to keep in repair be all inevitable problem, the most appropriate method exactly admission line is set to double-deck redundancy structure.
The technology that relates to double-skin duct in prior art is many, if the patent No. 201120570605.6 is for disclosing a kind of double-deck heat exchanging tube, comprises inner tube and makes pottery and be located at the outer tube outside inner tube, and inner and outer pipes fits tightly formation bimetallic tube.
The patent No. 201220414842.8 discloses another kind of structure bimetallic tube, and this bimetallic tube outside is cylindrical tube, is connecting 1 font partition in pipe, and the other end of 1 font partition is connecting columnar pipe.
Patent No. CN200910189016.0 discloses a kind of bimetal pipe and mfg. moulding die and manufacture method, and this bimetal pipe comprises inner tube and the external pipe of snug fit, comprises the passage that runs through bimetal pipe two ends between inner tube and external pipe.
The patent No. is 201210246597.9 disclose the compound gas pipeline of a kind of double-layer tube wall and for the leakage monitoring method of this pipeline, mainly solved high risk zone gas pipeline safety in operation deficiency and leakage point and be difficult to definite problem.It is characterized in that: between inner tube and outer tube, spatia is set, in spatia, carry out nitrogen replacement, the top of outer tube outer wall arranges some vertical arms that are communicated with spatia, the top of vertical arm arranges concrete slab and seals, sidewall is communicated with a reclinate arm, arm end is provided with pressure burst fragmentation, combustible gas probe is installed in concrete slab bottom surface, stretch into vertical arm inner, by analog signal line and RS485 data bus cable, be connected respectively to flammable gas alarm and the industrial computer in remote monitoring chamber, industrial computer calculates pipeline the position of leaking occurs, this kind of method can be safe and efficient definite leakage point.The technical problem that this programme solves is close with technical problem to be solved by this invention, but has difference with technology to be solved by this invention, is not suitable for and solves technical problem of the present invention.
Summary of the invention
Technical problem to be solved by this invention is to provide and a kind ofly can prevents gas leakage, is convenient to again the fuel gas supply conduit of safeguarding.
In order to solve the problems of the technologies described above duel fuel engine fuel gas supply conduit of the present invention, comprise inner tube, outer tube, it is inner that described inner tube is arranged on described outer tube, between described inner and outer tubes, be provided with interstitial cavities, also comprise travel(l)ing rest, described travel(l)ing rest is comprised of dunnage and U bolt, and described dunnage is connected in outer tube wall, described U bolt is arranged in dunnage, and described inner tube is arranged in described U bolt.Inner tube is for delivery of rock gas or other inflammable gass, and outer tube is used for preventing directly entering in working environment after inner tube combustible gas leakage.Interstitial cavities is set between inner and outer tubes, can when Leakage Gas, has the convenient storage in certain space.The support of internal layer pipeline can adopt the form of being welded and fixed, but is not easy to like this pipeline maintenance, adopts travel(l)ing rest to be fixed with and is beneficial to pipeline maintenance, once inner tube has breakage only this section need be disassembled and changes, very convenient.
As the further improvement for technique scheme, another technical problem to be solved by this invention is better to detect and safeguard internal layer pipeline, outer tube can adopt seamless pipeline as inner tube, once but inner tube is leaked, that must adopt the mode of machine cuts to break pipe to outer tube, very inconvenient, after being especially arranged on equipment, maintenance difficulty further strengthens.
For this reason, in the technological scheme of further improvement of the present invention, described outer tube is comprised of two symmetrical Baltimore grooves, and the trough rim of described Baltimore groove is provided with fixed strip, and the fixed strip of two Baltimore grooves is bolted.Adopt this structure to need only outer tube is taken apart when inner tube need to detect or keep in repair, can realize and detecting and maintenance, can not damage outer tube simultaneously.
Further improvement for above-mentioned two technological schemes is provided with vacuum pumping device in described interstitial cavities, and vacuum pumping device will vacuumize in interstitial cavities, if there is combustible gas leakage, in interstitial cavities, can not form gathering, and then cause danger.
Further improvement for above-mentioned all technological schemes is provided with gas detecting instrument in described interstitial cavities, once there is gas leakage, can pass through gas detecting instrument closing gas valve door, avoids continuing to leak.
Generally speaking, pipeline of the present invention can either prevent gas leakage, is convenient to again detection and the maintenance of fuel gas supply conduit, simple in structure, effective.
