The utility model further describes below with reference to the embodiment in the accompanying drawing.
Fig. 1 is a formation schematic representation of the present utility model.Fig. 2 is the sectional view of modulating valve.
By Fig. 1, the utility model is made of automobile inflating device, gas holder inflator.The automobile inflating device is made up of modulating valve 4, one-way valve 5, tracheae 2, three-way union 3,6, pressure gauge 8.Suction port 1 usefulness tracheae 2 connects with the mouth I of three-way union 3, its mouthful II connects with the inlet 22 of modulating valve 4 with tracheae 2, its mouthful III connects with the inlet of one-way valve 5 with tracheae 2, the outlet of one-way valve 5 connects with the mouth II of three-way union 6 with tracheae 2, its mouthful I connects with the control mouth 30 of modulating valve 4 with tracheae 2, its mouthful III connects with automobile inflating mouth 7 with tracheae 2, and pressure gauge 8 is installed on the automobile inflating mouth 7, and the outlet 23 usefulness tracheaes 2 of modulating valve 4 connect with the gas holder inflator.The gas holder inflator is made up of modulating valve 14,16, one-way valve 11,15, tracheae 2,9,10,12,17, three pressure gauges 8 of three-way union.Connect with the mouth I of three-way union 9 with tracheae 2, the mouth II of three-way union 9 connects with the inlet 22 of modulating valve 14 with tracheae 2, its mouthful III connects with the mouth I of three-way union 10 with tracheae 2, the mouth II of three-way union 10 connects with the inlet 22 of modulating valve 16 with tracheae 2, its mouthful III connects with the inlet of one-way valve 11 with tracheae, the outlet of one-way valve 11 connects with the mouth II of three-way union 12 with tracheae 2, the mouth I of three-way union 12 connects with the control mouth 30 of modulating valve 14 with tracheae 2, its mouthful III connects with gas holder inflation inlet 13 with tracheae 2, the outlet 23 usefulness tracheaes 2 of modulating valve 14 connect with the inlet of one-way valve 15, the outlet of one-way valve 15 connects with the mouth II of three-way union 17 with tracheae 2, the mouth I of three-way union 17 connects with the control mouth 30 of modulating valve 16 with tracheae 2, its mouthful III connects with gas holder inflation inlet 18 with tracheae 2, the outlet 23 usefulness tracheaes 2 of modulating valve 16 connect gas holder inflation inlet 13 with gas holder inflation inlet 19,18, a pressure gauge 8 respectively is installed on 19.
Compressed natural gas is imported from suction port 1 by compressor, through tracheae 2, mouth II, mouthful III of mouth I, mouthful III by three-way union 3, one-way valve 5, three-way union 6 is transported to automobile inflating mouth 7 or the mouth I by the three-way union 6 control mouth to modulating valve 4, by mouthful I of three-way union 3, the inlet 22 that mouth II is transported to modulating valve 4.At this moment, modulating valve 4 cuts out, and compressed natural gas can only be given automobile inflating by inflation inlet 7.Automobile inflating finishes, and closes inflation inlet 7, and the pressure in the tracheae 2 increases gradually.When reaching the cracking pressure 22MPa that modulating valve sets, from the pressure of the mouth I of three-way union 6 control mouth 30, modulating valve 4 is opened by modulating valve 4, compressed natural gas enters the gas holder inflator through inlet 22, the outlet 23 of this valve.The effect of one-way valve 5 is to prevent that compressed natural gas from flowing backwards, and pressure gauge 8 is to be convenient to the working condition that the operator observes inflator.The compressed natural gas that enters the gas holder inflator through tracheae 2 by the mouth I of three-way union 9, the inlet of mouthful II, through mouth II, mouthful III of mouth I, mouthful III of mouth I, mouthful III of three-way union 9, three-way union 10, one-way valve 11, three-way union 12 to gas holder inflation inlet 13 or through mouthful I of three-way union 12 control mouth 30 to modulating valve 14.Because modulating valve the 14, the 16th cuts out, compressed natural gas can only enter gas holder inflation inlet 13.When the pressure of the tracheae 2 that connects with inflation inlet 13 reaches 22MPa, modulating valve 14 is opened, compressed natural gas is through inlet 22, the outlet 23 of modulating valve 14, by tracheae 2, by mouth II, mouthful III of one-way valve 15, three-way union 17 to gas holder inflation inlet 18 or through mouthful I of three-way union 17 control mouth 30 to modulating valve 16.When the pressure of gas holder inflation inlet 18 reached 22MPa, modulating valve 16 was opened, and compressed natural gas arrives gas holder inflation inlet 19 through inlet 22, the outlet 23 of modulating valve 16.When the pressure of inflation inlet 19 reached 22MPa, compressor was simultaneously to 13,18,19 inflations of gas holder inflation inlet.When the pressure of three inflation inlets of gas storage tank device reached 25MPa, compressor quit work.Inflator has just been finished the sequential inflation of automobile inflating mouth 7, gas holder inflation inlet 13,18,19 automatically and accurately like this.In the utility model, at first satisfy the inflation of automobile inflating mouth 7.Even when inflating for the gas holder system, as long as opening automobile inflation inlet 7, because pressure reduces, modulating valve 4 cuts out automatically, device is just given automobile inflating by inflation inlet 7.When automobile inflating finishes, inflation inlet 7 is closed, and pressure increases, and when reaching 22MPa, modulating valve 4 is opened, and the gas holder gas charging system recovers inflation again.
Among Fig. 2, modulating valve 4,14,16 structure functions are identical.Constitute by valve gap 20, plunger 21, valve body 24, O RunddichtringO 25, the spring seat of honour 26, spring 27, valve seat 28, spring lower seat 29.The shell of modulating valve is connected together and is formed by valve gap 20, valve body 24, valve seat 28.Valve gap 20, valve body 24 is provided with a cylindrical hole vertically, the upper end of the lower end of valve gap 20 and valve body 24 connects firmly with screw, valve seat 24 is drums, on it, the lower end endoporus is provided with internal thread, the outside thread of the lower end of valve body 24 connects with the internal thread of the upper end of valve seat 28, spring lower seat 29 spinnings are gone in the interior threaded hole of valve seat 28 lower ends, spring lower seat 29 is being supported in the lower end of spring 27, the upper end of spring 27 heads on the lower edge of the spring seat of honour 26 intermediate flange, the upper end of 26 intermediate flange upper edges, the spring seat of honour and 24 times end in contact of valve body heads on the lower end of plunger 21, and the upper end of plunger 21 contacts with the lower edge of valve gap 20 endoporus intermediate flange; The endoporus bottom boring of valve gap 20 has a plenum openings, form upper gas chamber 31 with the top of plunger 21, the inlet 22 and upper gas chamber 31 UNICOMs of modulating valve, the top boring of valve body 24 has another plenum openings, form lower chamber 32 with plunger 21 bottoms, the outlet 23 and lower chamber 32 UNICOMs of modulating valve are equipped with three O RunddichtringOs 25 on the surface of contact of plunger 21 and valve gap 20, valve body 24 endoporus.
At shown position, the upper end of plunger 21 is positioned at the upper end of modulating valve endoporus, and plunger 21 middle and upper parts are provided with an air chamber groove along circumference, is used for the UNICOM of upper gas chamber 31 and lower chamber 32.General state, modulating valve cuts out, and upper gas chamber 31 and lower chamber 32 not conductings are when the pressure of inflation inlet reaches 22MPa, act on the pressure of plunger 21 upper-end surfaces by control mouth 30, overcome the elastic force that spring 27 makes progress, order about plunger 21 and move downward, this moment, modulating valve was opened, upper gas chamber 31 and lower chamber 32 conductings, compressed natural gas is from 22 inputs of modulating valve inlet, through upper gas chamber 31, lower chamber 32, from exporting 23 outputs.
By the model of selecting spring 27 and the axial displacement of passing through to use threaded adjustment spring lower seat 29, can determine the cracking pressure of modulating valve.
