Embodiment
Below in conjunction with the accompanying drawing illustrated embodiment the utility model is described further.
The utility model relates to a kind of gas combustion automobile pressure reducing regulator, it is to be connected to form with outlet passageway 4 by the gas-entered passageway 3 in the housing 1, circulation heating water channel 2, one-level gas storehouse parts 7, secondary gas storehouse parts 9, three grades of gas storehouse parts 12, circulation heating water channel 2 heats around gas-entered passageway 3 peripheries, and the gas storehouse inner chamber maximum height of three grades of gas storehouse parts 12 is 22mm.
The utility model mainly is the composite structure that is linked to be by pressure gauge of 3,1 grades of gas storehouse parts of gas-entered passageway parts, electromagnetic valve part 5, belt sensor etc.The working procedure of three grades of decompressions is such, when pressurized gas enter suction port of the present utility model by pipeline, enter gas-entered passageway 3 by pneumatic filter after with the contaminant filter in the gas, this moment, pressurized gas were opened air inlet valve nozzle plug 6, and entered in the one-level gas storehouse parts 7, because 7 spaces, one-level gas storehouse want big many than gas-entered passageway 3, so gas enters back expansion rapidly in the one-level gas storehouse parts 7, pressure descends rapidly, and this process will absorb a large amount of heats, and gas cooling is frozen.So should adopt the heating of engine cycles water at gas-entered passageway 3 positions, to guarantee the normal circulation of gas.Then the gas in the one-level gas storehouse parts 7 backs down the valve nozzle rubber pad 8 in secondary gas storehouse and enters in the secondary gas storehouse parts 9.Because secondary gas storehouse 9 than 7 spaces, one-level gas storehouse more greatly, so gas step-down once more.When electromagnetic valve part 5 is opened, the medium pressure gas in secondary gas storehouse 9 is opened the valve nozzle rubber pad 11 in three grades of gas storehouses and is entered in three grades of gas storehouse parts 12, three grades of gas storehouses 12 are than big many in the space in secondary gas storehouse 9, so gas carries out step-down for the third time after entering in three grades of gas storehouse parts 12, and reaches required working pressure.Gas enters in the motor of automobile by the outlet pipe 4 of three grades of gas storehouse parts 12 then, has so far finished its decompression.Three grades of step-downs can make step-down distribute rationally, reduce the volume and weight of valve body, make product have good reliability, Security and Economy.
This pressure reducing regulator also possesses the function of automatic pressure regulation size in decompression, when one-level gas storehouse 7 reaches rated pressure, the rubber gasket 10 in one-level gas storehouse expands, the column 13 and the lobe plate 14 that drive one-level gas storehouse produce displacement, make air inlet valve nozzle plug 6 block one-level gas storehouse air inlet valve nozzle 15, gas circuit will be cut off.In like manner, when the pressure in one-level gas storehouse 7 is lower than rated pressure, gas circuit will be got through once more.Equally, when the pressure in two, three grades of gas storehouses 9,12 acquired a certain degree, gas circuit is blocked or got through to the valve nozzle that the rubber pad 8,11 in two, three grades of gas storehouses will drive separately.
Prior art is used one-sided circulating water heating at gas-entered passageway 3 places, the heating efficiency deficiency, circulating water heat tunnel 2 of the present utility model is around heating around the gas-entered passageway 3, increased hot area, improved the gas atomization effect, rock gas can fully fully be burnt, increase automobile running power.Automobile in the process of moving, because of reasons such as the unexpected variation of external environment condition and vehicle conditions itself, motor moment needs big air demand, and promptly the space in three grades of gas storehouses is too little in the gas storage storehouse of existing technology, does not satisfy needs.The space, gas storehouse of three grades of gas storehouse parts 12 of the present utility model has obtained expansion, and the gas storehouse inner chamber maximum height of three grades of gas storehouse parts 12 expands to and is 21mm-23mm; And its preferred maximum height is 22mm, such height increase can make the volume in three grades of gas storehouses enlarge about 10%, promptly being 290 cubic millimeters by three grades of gas storage capacity of prior art expands to about 320 cubic millimeters, improve the gas storage capability of pressure reducing regulator, guaranteed the continuous driving force of travelling of automobile.Circulating water heat tunnel 2 of the present utility model can also heat around 1 to 3 circle around the gas-entered passageway 3,
The utility model improves the structure of circulation heating water channel, improves the temperature at pressure reducing regulator suction port place, increases the gas atomization effect, in order to the fully burning in motor of sky hot gas, cuts down the consumption of energy; The utility model increases the gas storage volume in pressure reducing regulator third level gas storehouse, guarantees that air feed is stable, improves the continuous driving force of automobile running; Adopt rational pressure reducing mode and structural change cleverly simultaneously, make the utility model compact structure, volume little, in light weight, improved reliability of products simultaneously, Security and Economy..
