Technical field
The invention belongs to combustion gas tractor truck technical field in the long-tube trailer transportation, a kind of 8 eight-tube automatic gas supply and supplementation device of high-pressure gas long tube semi-trailer particularly are provided.
Background technology
Present application along with long-tube trailer, the combustion gas tractor truck also more and more is subjected to user's favor, because natural gas filling station is less relatively, general combustion gas traction natural fuels that headstock is adorned only reaches about 200 kilometers distance, for distance far away slightly, if do not have gas station on the road, gas combustion automobile can't normally move, and for solving the problems referred to above of user, my company has invented from the air feed making-up air device, can under the situation of source of the gas deficiency, replenish with the natural fuels in the trailer gas cylinder.
Summary of the invention
The object of the present invention is to provide a kind of 8 eight-tube automatic gas supply and supplementation device of high-pressure gas long tube semi-trailer, solved the user draws headstock source of the gas deficiency in natural gas transportation trouble and worry, realized safe and reliable.
The present invention includes preceding end plug, safety device, to silk, ball valve, aie escape valve, T-pipe joint, ready-packaged joint, tonifying Qi hose construction; Preceding end plug one end is assembled on the lower-left bottleneck of front deck, and an end is equipped with the Type B safety device, and " " inlet ball valve is connected elbow, and ball valve is connected with T-pipe joint, connects tonifying Qi aie escape valve and ready-packaged joint male on the T-pipe joint with NPT1/2 by NPT1/2 again.
The tonifying Qi hose construction is made up of ready-packaged joint female and high-pressure rubber pipe, tee ball valve, handle and bolt-type filling gas mouth or air filling gun head; Removable at ordinary times transferring in the tool box.
Ready-packaged joint of the present invention is the G3/8 ready-packaged joint; To silk is that NPT1/2 is to silk; Ball valve is the NPT1/2 ball valve.
Innovative point of the present invention: be end plug before an end is installed on the gas cylinder of the lower-left of front deck, the other end is connected with the Type B safety device, " inlet ball valve is connected; ball valve is connected with T-pipe joint; connect tonifying Qi aie escape valve and ready-packaged joint male on the T-pipe joint, ready-packaged joint female and high-pressure rubber pipe, tee ball valve, handle and bolt-type filling gas mouth or air filling gun head have been combined into the tonifying Qi hose construction with NPT1/2 by the NPT1/2 elbow again.
The invention has the advantages that:
1, high pressure hose unitized construction has adopted the technology of gas station requirement, high-pressure rubber pipe, and tee ball valve is connected with the trailer gas cylinder with the G3/8 ready-packaged joint,
2, it is convenient and swift to get gas, and flow area is big, and is safe and reliable;
3, take into full account the user conveniently, two places are provided with aie escape valve;
4, filling gas mouth is provided with check valve, and ready-packaged joint has self-locking structure, guarantee not advance air in the high-pressure rubber pipe, thus safer.
5, not only convenient and swift, safe and reliable, the efficient height also greatly reduces user's traffic cost, has obtained user's favorable comment.
