Description
Technical field
The present invention relates to natural gas cylinder technical fields, specially a kind of to be suitable for the Vehicular liquefied natural gas cylinder of small volume
Guard circle modular construction.
Background technique
Vehicular liquefied natural gas cylinder: liner medium for storing is liquefied natural gas, and interlayer is high vacuum multiple layer heat insulation form,
Shell is used to support liner and stroke confined space, is equivalent to fuel tanks of automobile；Protect coil assembly: for protecting gas cylinder bottle valve
Door, instrument, pipeline, prevent it to be accidentally impacted and damage.
Automobile liquefied natural gas bottle is to contain, storage, supply fuel (liquid as one kind to substitute automotive oil tank
Change natural gas), and the low-temperature heat-insulation pressure container filled can be repeated several times.All exterior lines of gas cylinder, valve member, instrument
It is all disposed within one end of gas bottle head, to prevent the injury of direct mechanical collision or road gallet to instrument, usually in gas
Bottle valve end welding protection coil assembly is protected.The guard circle modular construction in industry has 2 kinds at present, a kind of gas bottle head
In valve, pipeline are wrapped in by an annular circle and 3-4 support plate, the peace such as the filling opening and gas returning port of gas cylinder, pressure gauge
On liquid feeding panel, liquid feeding panel is fixed on the supporting plate, which is suitable for the gas cylinder of all diameters；Another gas cylinder
The pressure gauge of filling opening, gas returning port and gas cylinder is fixed on guard circle, and valve, the pipeline of gas bottle head are all wrapped in by guard circle
Interior, outside is covered with a cover board, is provided with hand hole in the corresponding position of valve on cover board, is facilitated manual switch valve.The knot
Structure is only applicable to diameter in the gas cylinder of 650mm or more.
Since small volume gas cylinder diameter is small in the prior art, the assembly space of Bottleneck valve, instrument and pipeline is limited, and
Since guard circle radius of curvature is small, pressure gauge fixing bolt tightens rear pressure gauge dial plate and easily deforms, so as to cause pressure gauge
The raw leakage of interior shockproof fry dried food ingredients, guard circle modular construction are not used on small volume gas cylinder, although guard circle meets assembly space
Requirement, can only but prevent valve, pipeline, instrument from by direct mechanical collision, road surface in vehicle travel process cannot not prevented
The injury of rubble, while and valve pipeline on be easy to cause dust dirt to accumulate, therefore need to research and develop and a kind of be suitable for small volume
The guard circle modular construction of Vehicular liquefied natural gas cylinder.
Summary of the invention
The purpose of the present invention is to provide a kind of protection coil assembly knots suitable for the Vehicular liquefied natural gas cylinder of small volume
