Description
Technical field
The present invention relates to a kind of automobile liquefied natural gas bottle, it is particularly suited for the vapour with crossover sub Vehicular liquefied
Natural gas cylinder, belongs to low-temperature heat-insulation pressure container applied technical field.
Background technology
Liquefied natural gas bottle is a kind of cryogenic liquid insulated gas cylinder, and in background technology, liquefaction both domestic and external is natural at present
It is all using " dispensing head-stainless-steel pipe-control valve-stainless steel steel that gas bottle manufacturer controls installing for valve at it
The connected mode of pipe-connector-exterior line ", i.e. multiple interfaces in dispensing head are welded many stainless-steel pipes, then
Stainless-steel pipe is welded to one end of control valve, the other end of valve again by be welded stainless-steel pipe and jointing with
Exterior line is connected.
The major defect that this connected mode exists in actual use is many leakage points, is manufactured and difficult in maintenance.
Once valve has damage, it is necessary to which carrying out stainless-steel pipe cutting and welding can just carry out the maintenance or replacing of valve, same to time-division
The increase of heat transfer can be caused with an external long stainless-steel pipe, is unfavorable for the thermal insulation of low temperature cylinder, and increased
Weld leakage point.
In addition, stainless-steel pipe is that welding is got on when gas cylinder is assembled between valve and valve body, processing technology is not so good.
Not enough present on to overcome, the dispensing head to Vehicular liquefied natural gas cylinder is developed, and dispensing head is designed to two
Part：Crossover sub and multifunction valve valve body, install multifunction valve on crossover sub.Eliminate each valve and crossover sub it
Between connecting pipe, reduce leakage point, structure is compacter and attractive in appearance, and security is relatively reliable, and processing technology is good, maintenance
It is convenient and swift.
The content of the invention
The present invention is intended to provide a kind of automobile liquefied natural gas bottle, by part valve of the prior art on the gas cylinder
By redesigning, it is separately mounted on a common valve body for porous similar short cylindrical shape, constitutes a multifunction valve.Should
Valve is in the assembling of gas cylinder front-end-of-line as a part of LNG gas cylinders, is assemblied on crossover sub after the assay was approved, is processed
Good manufacturability.
To achieve these goals, the technical solution adopted in the present invention is：
A kind of automobile liquefied natural gas bottle, including bottle component are more on bottle component by crossover sub
Duty valve；It is structurally characterized in that, topping up interior inlet is provided with the valve body of the multifunction valve, with gas entrance, with liquid entrance, liquid

12 enter, and flow through topping up check valve assembly 6 and enter gas cylinder through gas cylinder liquid-filling pipe again.Meanwhile, bottle internal upper part gas part stream
Cooled via return air stop valve 9 arrives gas returning port, is connected with exterior line.Another part enter valve body through main safety valve 22, secondary safety valve 21,
Pressure gauge 23 and liquid level gauge, the pressure and change in location of liquid in their dynamic detection whole process, when air pressure exceedes peace in bottle
During full valve release pressure, safety valve work.When setting position is reached, then stop topping up, topping up check-valves 11 is automatically switched off.
2. during gas cylinder liquid, open return-air stop valve 9 and go out liquid shut-off valve assemblies 13.
1）When gas pressure sets pressure higher than economic air throttle 18 in bottle, economic air throttle 18 is opened, interior check-valves
16 close, in bottle gas through economic air throttle 18, go out liquid stop valve 13, excess flow valve 14, gas is able to preferentially use.
2）When gas pressure sets pressure less than economic air throttle 18 in bottle, economic air throttle 18 is closed.Liquid in bottle
Through interior check-valves 16, it is connected with external pipe to liquid stop valve 13, excess flow valve 14 is gone out.When with hypertonia in liquid pipe road, portion
Divide liquid to return gas cylinder through the throttling pore of interior check-valves 16, maintain balance.
The present invention thoroughly solves what welding when part valve in the prior art is assembling was got on, once misoperation,
Remedy and be difficult or even scrap.And weld inconvenience polishing, unsightly.And eliminate the connecting tube between each valve and dispensing head
Road, reduces leakage point, and structure is more compact attractive in appearance, and security is relatively reliable.Maintainability is good, when valve breaks down, only
Screw thread is unclamped to back out, it is convenient and swift.
The content that above-described embodiment is illustrated should be understood to that these embodiments are only used for being illustrated more clearly that the present invention, without
For limiting the scope of the present invention, after the present invention has been read, those skilled in the art are to the various equivalent form of values of the invention
Modification each fall within the application appended claims limited range.
