Abstract
The utility model discloses a mixed gas dispenser which comprises a cabinet, two gas inlet tubes and a control device (14), wherein the two gas inlet tubes are respectively connected with a gas mixing tank (4) through a flow control valve (3), the gas mixing tank (4) is connected with a filter (7), the filter (7) is connected with a dispensing hose (18) and a dispensing gun (19) through a stop valve (11), and the flow control valve (3) and the stop valve (11) are connected with the control device (14). When the mixed gas dispenser disclosed by the utility model is used for dispensing gas to an automobile, the gas is mixed, and the gas mixing ratio can be well controlled through the gas flow control valve, so that the automobile power is improved, and the emission of tail gas pollutants is alleviated.
Description
Technical field
The utility model relates to a kind of mixed gas aerator.
Background technique
The development of automobile brings oil shortage and the problem of vehicle exhaust to environmetal impact, alternative fuel vehicle enjoys people to pay close attention to, general vehicle alternative fuel is rock gas, liquefied petroleum gas (LPG), ethanol etc., can well solve exhaust emissions problem, but power character deficiency is the significant deficiency of alternative fuel vehicle.In order to improve alternative fuel vehicle power character, lot of domestic and international scientific research institution proposes the way that fuel is mixed burning, when empirical tests adopts fuel combination, the problem of alternative fuel vehicle power character deficiency can be resolved, the key of fuel combination is the accurate control of fuel mixture ratio, show according to the study natural gas-hydrogen mixture 20% ~ 30%, power character is best, and oxynitrides, pellet and HC also have decline significantly.If in advance the good mixed gas of proportioning is stored in air cylinder group, because gas density is different, mixed gas in air cylinder group has stratification to a certain extent, can cause the proportions of ingredients of fuel when refueling to change, and affects automobile dynamic quality and emission performance.
Summary of the invention
The technical problems to be solved in the utility model: for mixed gas, in air cylinder group, there is the problem of layering, provide a kind of fuel combination filling machine when to refueling by combustion gas mixing.
Technical solutions of the utility model:
A kind of combination gas filling machine, comprise cabinet, suction tude and control gear, suction tude has two, by flow control valve, connect combustion gas mixing tank respectively, combustion gas mixing tank is connected with filter, filter connects aerating flexible pipe and air filling gun by stop valve, and flow control valve is all connected with control gear with stop valve.
Between filter and stop valve, with cross fitting, connect, two other interface of cross fitting is respectively by Decompression valves Connection Cache gas cylinder, and Decompression valves connects control gear.
Between combustion gas mixing tank and filter, be provided with baroceptor and block valve, both connect control gear.
The entrance point of aerating flexible pipe is provided with metering mechanism and baroceptor, is all connected with control gear.
Cabinet is the vertical gas holder that adds, and is provided with aerating control panel and display device, is all connected with control gear.
The utility model beneficial effect:
This fuel combination filling machine by combustion gas mixing, and can be controlled better combustion gas mixing ratio by gas flow control valve when giving refueling, improves better vehicle dynamic quality, reduces the discharge of exhaust pollutant.
By closing of stop valve and block valve, can to filter, change easily.
By baroceptor, can effectively indicate and add atmospheric pressure, if aerating pressure anomaly is closed stop valve and air inlet pipeline, open Decompression valves simultaneously, make the gas existing in filling machine enter buffer memory gas cylinder, improve the Security of filling machine.
Unit processed is by circuit and flow control valve, baroceptor, and block valve, Decompression valves, metering mechanism, aerating control panel, display device is connected, and it is control effectively, and controls better gas mixture ratio, improves the Security of filling machine.
