Description
Technical field
The present invention relates to car bottle field, particularly relate to a kind of LNG car bottle threshold limit values charging device.
Background technology
LNG car bottle belongs to cryogenic insulated cylinder, internal equipped with liquefied natural gas, is the LNG fuel such as heavy truck, intercity public transport
The Core equipment of car air supply system, gas cylinder internal is typically provided with 10% gas-phase space, and the LNG car bottle that market uses is the most all
There is excess topping up problem, its structure is that bottle inner bag is provided with gas phase inner chamber, and intracavity bottom is provided with an aperture, and topping up is permissible first
Playing threshold limit values topping up, interior liner liquid reaches pressure balance afterwards, and liquid is entered in gas-phase space by aperture.As following specially
Profit is described:
Patent CN201420280816.X discloses a kind of liquefied natural gas bottle topping up automatic limit device, including: storage
Tank, cryopump, vacuum heat-insulating hose, ready-packaged joint, liquefied natural gas bottle, spray pipeline and surge tank.Liquefied natural gas leads to
Crossing cryopump to be connected with vacuum heat-insulating pipe, vacuum heat-insulating pipe is connected with spray pipeline by ready-packaged joint；Spray pipeline is arranged on
The inner upper end of liquefied natural gas bottle.Surge tank is arranged on inside liquefied natural gas bottle, and the bottom of surge tank offers
Through hole.The liquefied natural gas bottle topping up automatic limit device that this utility model provides, is provided with surge tank, at liquefied natural gas
After having inflated, reaching gas-liquid phase equilibrium through after a while, the partial liquefaction natural gas in liquefied natural gas bottle enters
In surge tank so that sufficiently large substitute phase space occurs in liquefied natural gas inner upper end, it is to avoid filling liquefaction sky
So produce situation about overcharging during gas.
Patent CN201320187358.0 discloses a kind of Vehicular liquefied natural gas cylinder inner bag, and cylinder liner one end is arranged
Having substitute phase space, be provided with feed liquor shower and capacitance level gauge in the gallbladder of cylinder liner, described feed liquor shower sets
Putting on gallbladder wall, described capacitance level gauge is arranged on centre position in the gallbladder of cylinder liner.This utility model is provided with safety
Gas-phase space, it constitutes vacuum space with shell, the most more can protect inner bag and gas cylinder plays supporting and protecting effect.From its explanation
Describing it can be seen that be also to have offered an aperture in the bottom of its substitute phase space in book and accompanying drawing.
Patent CN200720138400.4 discloses a kind of cryogenic insulated cylinder, structure includes shell, inner bag, be positioned at outside
It is wound in the heat insulation layer on inner bag, the accessory case being arranged on shell between shell and inner bag and is fixed on this accessory case and bottleneck
Topping up pipe, drain pipe and gas phase pipe between plug.Key Design is: is wound with one end between the inner bag of heat insulation layer and shell and adopts
Realizing being located by connecting with cylindrical support, the other end uses the sliding supporting structure with axial freedom to realize dynamic cooperation even
Connect；Topping up pipe is axially disposed within inner bag top at inwall and uniform spray hole vertically upward；The other end of inner bag is provided with
Put air chamber, air chamber wall is respectively arranged with a passage along vertical is upper and lower.
Current prior art and the operation principle of above-referenced patent are as follows: liquefied natural gas from storage tank through low temperature
Being pumped into inside liquefied natural gas bottle, when liquid fills, the liquid in bottle can be by the through hole arranged bottom surge tank
Slowly enter in surge tank.After liquefied natural gas arrives liquefied natural gas bottle inner tip, outside surge tank, fill up liquefaction sky
So gas, surge tank because of its internal gas pressure in relatively conference makes liquefied natural gas bottle liquefied natural gas enter slowly, now continue
Continuous topping up can make the pressure in liquefied natural gas bottle be rapidly increased to the maximum output pressure of cryopump so that cryopump stops
Being filled with liquefied natural gas, now surge tank inner upper end leaves certain expansion space.When stopping being filled with liquefied natural gas one section
After between, in liquefied natural gas bottle and surge tank, reach gas-liquid phase equilibrium, the partial liquefaction natural gas in liquefied natural gas bottle
Surge tank is entered so that sufficiently large safe gas phase occurs in liquefied natural gas bottle inner upper end by the through hole bottom surge tank
Space, it is to avoid produce situation about overcharging when filling liquefied natural gas.
But, at present merely open the way of pore at gas phase intracavity bottom or the end-top and yet suffer from bigger drawback,
Owing in gas phase intracavity space, liquid can not be discharged for a long time in time, thus reduce gas-phase space, cause the gas cylinder too fast band of boosting
Carrying out potential safety hazard, this problem is also those skilled in the art's problem demanding prompt solution.
Summary of the invention
According to above the deficiencies in the prior art, the present invention provides a kind of LNG car bottle threshold limit values charging device, solves
During each topping up of LNG car bottle, cylinder liner all can leave constant safe space, and this device is convenient to be installed, simple in construction, energy
Enough effective prevention gas-phase spaces reduce the potential safety hazard brought.
Its technical solution is:
A kind of LNG car bottle threshold limit values charging device of the present invention, it is characterised in that: include cylinder liner, gas
Phase inner chamber, implementation of port and coil, described cylinder liner one end is provided with implementation of port, is provided with gas phase inner chamber in the other end,
Described gas phase inner cavity top offers a passage, and being connected between described passage with cylinder liner inner top has vertical cloth
The coil put.
Wherein, preferred version is as follows:
Diameter≤the 5mm of described passage；
The bending extension direction of described coil is level, in the help of gravity, effective delays liquid flows into gas phase
In chamber.
Latus rectum≤the 5mm of described coil, latus rectum is little, effectively stops pressure to rise too fast and cause liquid in the short time
Flow in gas phase inner chamber.
The present invention can be equipped with liquidometer according to actual needs, and capacitance level gauge preferably used by liquidometer；Enter
Liquid mode can also select fountain, i.e. connects a shower from implementation of port position, and this shower is along cylinder liner
Top layout, spray mode can effectively suppress the generation of heat energy.Above-mentioned these improve the selection belonging to existing conventional techniques,
Belong in the protection domain of patent of the present invention.
The use process of the present invention is as follows: when LNG liquid rises to cylinder liner top, and passage is connected with coil,
When liquid enters gas phase inner chamber by coil, in the short time, snakelike overpressure steeply rises the specified pressure reaching implementation of port
Power, implementation of port quits work, within now liquid does not the most arrive gas phase inner chamber, it is ensured that leave constant substitute phase space,
After using a period of time along with the LNG liquid in cylinder liner, the liquid being retained in coil is in the gas phase of cylinder liner
In space, liquid can evaporate, and at this moment coil returns to initial condition.
The present invention is had the beneficial effect that the passage of (1) gas phase inner chamber is communicated to cylinder liner by coil
Inner top, when liquid by coil enter gas phase inner chamber time, in the short time, snakelike overpressure steeply rises and reaches topping up
The rated pressure of mouth, implementation of port quits work, and within now liquid does not the most arrive gas phase inner chamber, remains constant gas phase
Space；(2) coil latus rectum is little, can effectively stop pressure to rise too fast and cause liquid to flow into gas phase inner chamber in the short time
In.
