Abstract

The utility model discloses a kind of compressed natural gas used as vehicle fuel device, comprise air cylinder, air entraining valve, solenoid valve, cylinder and inflator, described inflator connects described air cylinder by air entraining valve, connected electromagnetic valve between described air entraining valve and described cylinder, is connected with one-way valve between described inflator and described air entraining valve.The utility model is by between aerator and air entraining valve, one-way valve being set, and when there is misoperation, one-way valve without any leakage, has prevented the generation of serious accident in cut-off state.

Description

A kind of compressed natural gas used as vehicle fuel device
Technical field
The utility model relates to gas station technical field, particularly a kind of compressed natural gas used as vehicle fuel device.
Background technique
CNG(Compressed Natural Gas, compressed natural gas) substation trailer arrives after CNG air entraining substation, will unload gas flexible pipe be connected with hydraulic substation prying body by ready-packaged joint.After system connects, start hydraulic substation prying body or monitor hydraulic system pressure when low in PLC control system, high-pressure hydraulic pump is started working, PLC automatic control system can be opened the liquid flowing valve of a steel cylinder and the valve of giving vent to anger, high-pressure liquid medium is injected to a steel cylinder, guarantee that in the trailer steel cylinder of CNG substation, gas pressure remains on 20-22Mpa, CNG after CNG high pressure air-out hose enters substation prying body knock out drum, is delivered to CNG filling machine to CNG fuel automobile aerating through high-voltage tube by steel cylinder air outlet.During aerating, by air entraining valve, to air cylinder, inflate, then air cylinder by air entraining valve and solenoid valve to automobile cylinder aerating.
But at filling machine, also have following problem in to refueling process, because air entraining valve position is near motor car engine, and hull-skin temperature during engine running is higher.When operator or driver's misoperation, may cause the rock gas in air cylinder to leak, have an accident.
Model utility content
In order to solve current compressed natural gas used as vehicle fuel device because thereby misoperation causes the problem of serious accident, now provide a kind of compressed natural gas used as vehicle fuel device.Concrete technological scheme is as follows:
A kind of compressed natural gas used as vehicle fuel device, comprise air cylinder, air entraining valve, solenoid valve, cylinder and inflator, described inflator connects described air cylinder by air entraining valve, and connected electromagnetic valve between described air entraining valve and described cylinder is connected with one-way valve between described inflator and described air entraining valve.
Described air entraining valve is two-way shut-off valve.
Compared with prior art, the compressed natural gas used as vehicle fuel device that technique scheme provides has the following advantages: by one-way valve being set between aerator and air entraining valve, when there is misoperation, one-way valve without any leakage, has prevented the generation of serious accident in cut-off state.
Accompanying drawing explanation
In order to be illustrated more clearly in the technological scheme in the utility model embodiment, below the accompanying drawing of required use during embodiment is described is briefly described, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the compressed natural gas used as vehicle fuel apparatus structure schematic diagram that the utility model provides.
Embodiment
For making the purpose of this utility model, technological scheme and advantage clearer, below in conjunction with accompanying drawing, the utility model mode of execution is described in further detail.
As shown in Figure 1, the utility model embodiment provides a kind of compressed natural gas used as vehicle fuel device, comprise air cylinder 1, air entraining valve 2, solenoid valve, cylinder and inflator 4, inflator 4 connects air cylinder 1 by air entraining valve 2, connected electromagnetic valve between air entraining valve 2 and cylinder, is connected with one-way valve 3 between described inflator and described air entraining valve.Air entraining valve 2 is two-way shut-off valve.
During inflation, inflator 4 is communicated with air cylinder 1 through one-way valve 3 and air entraining valve 2, gives air cylinder 1 aerating, and now air entraining valve 2 is opened air inlet switch, and closes out air cock, closes the active channel of connection, and rock gas pours air cylinder 1.After having filled, close air entraining valve 2 inlet air pathways, open the path of giving vent to anger, be communicated with active channel, by electromagnetic valve rock gas, enter cylinder.Rock gas is filling air cylinder by one-way valve 3 through air entraining valve 2, even if there is misoperation, the rock gas in air cylinder can not revealed yet, and therefore, can guarantee natural gas leakage accident not to occur when air entraining valve breaks down or be not closed completely yet.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
