In the compressed natural gas for automobile filling machine structure described in the utility model, pressure transmitter, mass flowmenter and solenoid valve etc. are all adopted nut alive and are connected very convenient maintenance with link; And by between one-way valve and solenoid valve and the pressure transmitter place Decompression valves is set, make it possible to timely pressure release, ensure the safety of natural gas aerating machine.
Description of drawings
Fig. 1 is the schematic representation that automobile described in the utility model is used the natural gas aerating machine structure.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail, can implements according to this with reference to the specification literal to make those skilled in the art.
As shown in Figure 1, compressed natural gas for automobile filling machine structure described in the utility model comprises the filter, one-way valve, solenoid valve, mass flowmenter, Emergeny Cutoff Valves, Pull breaking ualve and the air filling gun mouth that sequentially arrange and pass through link and connect; Also comprise electronics controlling device and pressure transmitter, described pressure transmitter is arranged between Emergeny Cutoff Valves and the Pull breaking ualve, described electronics controlling device is connected with flowmeter with pressure transmitter respectively, and control solenoid valve according to the quality of natural gas signal of the natural pressure force signal of the pressure transmitter collection of its reception and mass flowmenter collection and open or close, for ease of maintenance, strengthen the maintainalbility of filling machine and save operating cost, in the utility model, described pressure transmitter, mass flowmenter and solenoid valve all adopt nut alive and are connected with link.
The filter at described gas inlet place adopts has the structure of replaceable filter core, thereby can be convenient for cleaning, be convenient to check and replace, the degree of purity of the rock gas that passes through with guarantee, and increase working life of solenoid valve and aerating automobile steel cylinder.
In the utility model, for ensureing the safety of natural gas aerating machine, also be provided with the many places pressure relief device.Particularly, as shown in Figure 1, be provided with the threeway Decompression valves between described one-way valve and solenoid valve, an end of this threeway Decompression valves is connected with one-way valve, the other end is connected with solenoid valve, the 3rd end has then connected outside pressure relief device.Because the impact of one-way valve self gravitation, if adopt cross setting can make its inner core distortion and produce deviation, working life and the performance of one-way valve exerted an influence, therefore, in the utility model, one-way valve vertically arranged and be communicated with aforesaid threeway Decompression valves.
Also be provided with the four-way Decompression valves in described pressure transmitter joint, described pressure transmitter is connected with Pull breaking ualve with Emergeny Cutoff Valves by the four-way Decompression valves, even the pressure relief device of an end Bonding pressure transmitter of this four-way Decompression valves, the second end connection Emergeny Cutoff Valves, the 3rd end connection Pull breaking ualve, the 4th end connection outside.
Automobile described in the utility model is as follows with the working procedure of natural gas aerating machine:
The air filling gun mouth is connected the automobile steel cylinder, open the suction valve of gas holder, open the Emergeny Cutoff Valves of filling machine, and by electronics controlling device input aerating signal, make solenoid valve open.Rock gas flow through successively filter, one-way valve, solenoid valve, mass flowmenter, Emergeny Cutoff Valves, Pull breaking ualve, and the air filling gun mouth after enter the automobile steel bottle.The signal of gaseous mass of mass flowmenter of flowing through will transfer to the electronics controlling device and calculate, and determining the corresponding volume of rock gas, the amount of money, and carry out output display by display device.After being converted to electrical signal, gas pressure signal by the pressure transmitter collection enters electrometer control device, when the air pressure of automobile steel cylinder reaches setting value, and closed electromagnetic valve in the filling machine and stop aerating.Afterwards, close suction valve and the air filling gun mouth taken off on automobile.For the rock gas that stockpiles between solenoid valve and the suction valve, can be discharged by the threeway Decompression valves.
