Description
Technical field
The utility model relates to a kind of automobile-used LNG gas cylinder self-supercharging device.
Background technique
Automobile LNG gas cylinder is the fuel storage facility of low-temperature liquefaction gas-fueled vehicles, and when under the prerequisite that gas cylinder provides steady fuel to supply for automotive engine system, automobile could stablize enforcement.This stable supplying fuel is by ensureing that the stable of fuel has transported to gas cylinder supercharging.
What generally use at present is LNG Liquefied natural gas in gas cylinder discharged through supercharging drain pipe from pressurization system, after the vaporization of sky bath formula vaporizer, then turns back to the gas-phase space of gas cylinder, to reach the object of supercharging.But along with gas cylinder gives automotive engine system transfer the fuel continuously, in gas cylinder, liquid level declines, and gas-phase space increases, and gas cylinder internal pressure declines gradually.Meanwhile, the deadweight of what the driving force of supercharging was leaned on is liquid in bottle, liquid overcomes the pressure drag of pipeline again, and drive the power of flow of fluid inadequate, cause the flow flowing through vaporizer little, evaporating capacity is inadequate, and pressurization time is elongated, and supercharging is stable not, continuously; And automobile is motion, the gas flowing into gas cylinder top is condensed into liquid, and pressure of the inside of a bottle enters a reduction; In addition supercharging drain pipe is a pipeline of drawing separately from gas cylinder, is exposed to outside bottle, does not have Emergeny Cutoff Valves unit protection; once supercharging fluid pipeline is touched disconnected; vaporization after large quantity of fluid ejection, runs into naked light meeting breaking out of fire and blast, therefore has very large potential safety hazard.
Model utility content
In order to overcome the above-mentioned shortcoming from pressurization system generally used at present, the utility model aims to provide a kind of automobile-used LNG gas cylinder self-supercharging device, this self-supercharging device can make automobile in the process of moving can from trend gas cylinder internal rapidly, continuously, stablize supercharging thus to the fuel of automotive engine system non-interruptible supply certain pressure to reach the object that automotive safety stablizes traveling.
To achieve these goals, the technological scheme that the utility model adopts is:
A kind of automobile-used LNG gas cylinder self-supercharging device, comprises automobile-used LNG gas cylinder, fluid stop valve, vaporizer, one-way valve and pressure charging valve; Its structural feature is, also comprises absorption caisson and gas phase stop valve; Described automobile-used LNG gas cylinder has liquid interface and intake interface, described in go out liquid interface, fluid stop valve, vaporizer be connected in series connection successively by pipeline; The outlet of described vaporizer connects two pipelines, and pipeline is used for being communicated with automotive engine system, another pipeline and one-way valve, adsorbs caisson, pressure charging valve, gas phase stop valve and is connected in series successively with intake interface and is communicated with.
Thus, vaporizer is communicated with automotive engine system with one-way valve respectively by pipeline, store when in gas cylinder, gas is sufficient, when in gas cylinder, gas is not enough, absorption caisson release gas to tonifying Qi in gas cylinder, thus to reach from trend gas cylinder internal rapidly, continuously, stablize supercharging thus to the fuel of automotive engine system non-interruptible supply certain pressure to reach the object that automotive safety stablizes traveling.
According to embodiment of the present utility model, can also do further to optimize to the utility model, the technological scheme below for being formed after optimization:
In order to promote vaporization ability, described vaporizer is water-bath type heater.
Described absorption caisson is built with sorbent.Further, described sorbent is active carbon nanoparticles.At normal temperatures, under 3.0MPa pressure, the adsorbable gas flow of active carbon nanoparticles is 150 times of volume volume, achieves effect that the little gas-storing capacity of absorption caisson volume is large.
Emergeny Cutoff Valves is equipped with in order to improve the Security of gas cylinder, the connecting pipeline between described fluid stop valve and vaporizer.
Thus, when in automobile-used LNG gas cylinder, gas pressure is greater than the setting pressure of one-way valve, one-way valve opens, when the setting pressure of the gas pressure in automobile-used LNG gas cylinder lower than pressure charging valve, absorption caisson is resolved and is released rock gas gas and also enter supercharging in bottle by gas phase stop valve; When the setting pressure of the gas pressure in automobile-used LNG gas cylinder higher than pressure charging valve, pressure charging valve cuts out automatically.
Compared with prior art, the beneficial effects of the utility model are:
1, because gas cylinder fills at hot bottle and stop using after an evening, its pressure of the inside of a bottle can raise, and the liquid of elevated pressures, after vaporizer vaporization, flows into absorption caisson through one-way valve and stores, pressurization gas steady sources.
2, when gas cylinder needs supercharging, supercharging is rapid, stable.
3, when automobile running rocks, period pressurization gas pressure high, speed is fast, and gas cylinder internal pressure is stablized, and can not cause the phenomenon of automotive engine system transient dynamics deficiency.
4, the fluid pipeline that inner bag supercharging is independent is eliminated, not only reduce the approach that gas cylinder leaks heat, improve the heat-insulating property of gas cylinder, avoid simultaneously and to have an accident because of automobile or in emergency circumstances cause pipeline breaking and produce large quantity of fluid eruption gasification, meet the hidden danger of fiery breaking out of fire and blast.
5, be provided with Emergeny Cutoff Valves in pressure piping, break in case of pressure piping or transfer the fuel pipeline meet accident, Emergeny Cutoff Valves is action immediately, cuts off cryogenic liquide circulation, improves gas cylinder air supply system safety.
Below in conjunction with drawings and Examples, the utility model is further elaborated.
