Abstract
The invention relates to a novel LNG (Liquefied Natural Gas) vehicle-mounted gas bottle liner support structure which is characterized in that a liner of a gas bottle is supported and fixed on a housing of the gas bottle; the support structure mainly consists of a liner end closure, a housing end closure, a manifold header, a support neck tube, an extension tube and a glass reinforced plastic ring; a reinforcing tube is sleeved outside the extension tube; one end of the reinforcing tube is fixedly connected with the inner wall of the liner end closure and the other end is fixedly connected with a second tube cap; and a vacuum cavity is formed between the reinforcing tube and the extension tube through vacuumizing. The novel LNG vehicle-mounted gas bottle liner support structure provided by the invention has few welding seams and is convenient to manufacture, and at the same time heat transfer is reduced and heat leakage amount is greatly reduced.
Description
Technical field
The present invention relates to cylinder liner and supporting structure technical field thereof, especially a kind of novel LNG mounted gas cylinder inner container supporting structure.
Background technique
LNG is the abbreviation of LNG Liquefied natural gas, it is the generally acknowledged clean energy resource in the world today, it has advantages of that calorific value is high, sufficient combustion, price are low, transport economic specific property and Security good, LNGV is the LNGV (liquefied natural gas vehicle) taking LNG Liquefied natural gas as fuel, and LNG mounted gas cylinder is the key component of LNGV onboard fuel system, LNG mounted gas cylinder is mainly made up of inner bag, shell, insulation system, support system and stiff member etc., and inner bag is in order to splendid attire LNG, and there are filling spraying tube, liquid-level probe etc. in inside.Between shell and inner bag, be airtight vacuum insulation chuck, chuck adopts high vacuum multiple layer heat insulation, claims again super thermal insulation.Shell protection inner bag also plays a supportive role to whole bottle, within inner bag is suspended on shell by the supporting system with high strength and good thermo-insulation properties.
At present, the inner bag of mounted gas cylinder is supported with extending type and Inner prolongs two kinds of formulas, in mobile or transportation process, inner bag easily vibrates, especially for the LNG mounted gas cylinder of full liquid, the conduct oneself with dignity bending of the support arm that causes of the LNG loading can not be left in the basket, and maximum stress mainly appears at neck tube and interior end socket joint.Chinese patent CN201020214317.2 discloses a kind of vehicle gas bottle inner container supporting device, comprises and supports heat insulating tube and fixed support cylinder, has circular groove at the right part of fixed support cylinder, and the left end that supports heat insulating tube is fixedly mounted on circular groove, Chinese patent CN200510120264.1 discloses a kind of inner container supporting structure of cryogenic insulated cylinder, extension tube (support heat insulating tube), its one end is connected with the interior end socket of this inner bag, its the other end extends in this inner bag and sealing, although above-mentioned two kinds of designs have all to a certain degree improved support strength and have reduced hot transmission, but the support tube leaking heat that shows two kinds of structures through hot analysis result is still very large, account for 50% left and right of the total leaking heat of gas cylinder, and whole apparatus structure is comparatively complicated, the inner container supporting structure of the interpolation type that CN200510120264.1 provides, short distance inside weld quantity is too much, be not easy to manufacture.
Summary of the invention
The technical problem to be solved in the present invention is: in order to overcome the larger technical problem of inner container supporting structure leaking heat in prior art, provide a kind of novel LNG mounted gas cylinder inner container supporting structure, reduced leaking heat, supporting structure weld seam is few simultaneously, manufactures simple.
The technical solution adopted for the present invention to solve the technical problems is: a kind of novel LNG mounted gas cylinder inner container supporting structure, the inner bag of gas cylinder supports and is fixed in the shell of gas cylinder, described supporting structure is mainly by liner end enclosure, shell end socket, manifold headers, support neck tube, extension tube and glass steel ring composition, described manifold headers one end is fixedly installed in shell end socket top, the other end is exposed to outside shell, extension tube one end is fixedly connected with liner end enclosure, the other end stretches into inner bag, the described extension tube end of stretching into inner bag part is connected with the first pipe cap, described support neck tube one end is connected with manifold headers, the other end stretches into extension tube bottom and is fixedly connected with the first pipe cap, between described support neck tube and extension tube, support by the glass steel ring being arranged on liner end enclosure, described extension tube is set with a reinforcement tube outward, reinforcement tube one end is fixedly connected with liner end enclosure inwall, the other end is fixedly connected with the second pipe cap, between described reinforcement tube and extension tube, form a vacuum chamber by vacuumizing.By adopting the structure of interpolation type, reduce weld seam quantity, improve support strength, adopt to support between neck tube and extension tube and support by glass steel ring, glass steel ring thermal conductivity is low, can reduce heat is delivered on liner end enclosure by supporting neck tube, pass through at the additional reinforcement tube of support device simultaneously, formation vacuum chamber will be vacuumized between reinforcement tube and extension tube, stop the LNG medium part that cylinder liner stores to contact with support neck tube, prevent that cryogenic media from directly contacting with supporting neck tube, reduces and leak heat.
In order to make device manufacture simple, described support neck tube and the first pipe cap place are welding.
Novel LNG mounted gas cylinder inner container supporting structure of the present invention, tool has the following advantages:
1, reduce leaking heat: by adopting the structure of interpolation type, reduce weld seam quantity, improved support strength, adopted to support between neck tube and extension tube and support by glass steel ring, glass steel ring thermal conductivity is low, can reduce heat and be delivered on liner end enclosure by supporting neck tube; At the additional reinforcement tube of support device, will between reinforcement tube and extension tube, vacuumize formation vacuum chamber, stop the LNG medium part that cylinder liner stores to contact with supporting neck tube, prevent that cryogenic media from directly contacting with supporting neck tube, reduces and leak heat;
2, simple in structure, easily manufactured: to adopt the structure of interpolation type, reduced weld seam quantity, improved support strength.
