Abstract
The utility model discloses a liquified petroleum gas filtering pressure-adjusting device used for a vehicle. A gas cylinder 1 is communicated with an inner cavity 4 of a pressure-adjusting device 2 by a delivery pipe 3; the inner cavity 4 is connected with a liquid inlet 8 of an electromagnetic valve 7 on an outer filter 6 by a delivery pipe 5; the periphery of the outer filter 6 is provided witha circle of water jacket 9, and a water inlet pipe 10 and a water outlet pipe 11 are arranged on the water jacket 9 and are connected with a circulating water cavity on the vehicle; and a gas outlet12 of the electromagnetic valve 7 is connected with a primary pressure-reducing valve core of the pressure-adjusting device 2 by a delivery pipe 13. The liquefied petroleum gas in the gas cylinder firstly absorbs heat by the pressure-adjusting device, then enters the peripheral water jacket of the filter for heating, evaporating and gasifying, then is filtered by a valve core of the filter and finally enters the pressure-adjusting device for reducing pressure. Therefore, the liquified petroleum gas filtering pressure-adjusting device guarantees that the gasified liquified petroleum gas entering the pressure-adjusting device is purified gas without containing impurities, thus preventing scale from depositing on the rubber valve core and the diaphragm in the pressure-adjusting device and avoiding function reduction and service life shortening. In addition, the liquified petroleum gas filtering pressure-adjusting device is externally provided with the filter, thus being convenient to remove impurities and maintain.
Description
Technical field
The liquid gas that the utility model relates on a kind of gas combustion automobile filters regulator.
Background technique
At present the liquefied petroleum gas on the gas combustion automobile be liquid liquefied petroleum gas in the gas cylinder earlier after filter cleaner filters, enter evaporation pressure regulator preheating, evaporation, pressure regulation with liquid form again, then with gas form to the motor car engine work done.Owing to contain plurality of impurities in the liquefied petroleum gas (LPG), enter filter cleaner with liquid state and filter and to filter clean impurity, after the liquefied petroleum gas that has impurity enters evaporation pressure regulator, be heated and be converted in the process of gas, impurity is attached on rubber spool, the elastomer diaphragm, and with the passing of time long-pending many, the dirt of spool and diaphragm thickens, uneven, causing becomes flat leaks gas, airtight not tight, causes the function reduction of evaporation pressure regulator, the lost of life, the evaporation pressure regulator of having to often change.
Summary of the invention
The purpose of this utility model is to provide a kind of filtration of gasifying, be convenient to maintain, the liquefied petroleum gas for car of long service life filters regulator.
Technical solution adopted in the utility model is, this liquefied petroleum gas for car filters regulator, comprise gas cylinder, pressure governor, filter cleaner, wherein, pressure governor comprises one-level reduction valve spool again, one-level reduction valve diaphragm, one-level reduction valve lever, the lever of second depressurized valve and spool, the reduction valve diaphragm, solenoid valve, pneumatic tube, the can regulate air valve, gas cylinder is through an intracavity inter-connection of delivery pipe and pressure governor, the liquid entering hole of the solenoid valve of this inner chamber on delivery pipe and external filter cleaner links to each other, external filter cleaner outer periphery one circle water jacket, establish intake pipe on it, outlet pipe, they are connected with circulating water cavity on the car, and the air outlet of the solenoid valve on the external filter cleaner links to each other with the one-level reduction valve of pressure governor through delivery pipe.
Owing to taked technique scheme, so the liquid liquefied petroleum gas in the utility model gas cylinder is to absorb heat through pressure governor earlier, enter the peripheral water jacket heating evaporation gasification of filter cleaner again, filter through the filter cleaner spool then, enter the pressure governor decompression at last.The gaseous liquefied petroleum gas that has so just guaranteed to enter pressure governor is pure gas free from foreign meter, no longer makes rubber spool, diaphragm deposition dirt in the pressure governor, reduces function, reduction of service life.Simultaneously, liquid gas earlier through the heating of pressure governor inner chamber, certainly will reduce cavity temperature in the pressure governor before entering filter cleaner, and the petroleum gas density that enters pressure governor after filter cleaner filters, gasifies is increased, and output power increases.In addition, the external filter cleaner of the utility model is convenient to removal of contamination, maintenance.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the utility model plane structure schematic representation.
Embodiment
Embodiment 1, as shown in Figure 1, this liquefied petroleum gas for car filters regulator, comprise gas cylinder 1, pressure governor 2, filter cleaner 6, wherein, pressure governor 2 comprises one-level reduction valve spool 16 again, diaphragm 17, lever 18, the lever 19 of second depressurized valve and spool 20, reduction valve diaphragm 21, solenoid valve 22, pneumatic tube 23, can regulate air valve 24, gas cylinder 1 is connected with the inner chamber 4 of pressure governor 2 through delivery pipe 3, the liquid entering hole 8 of the solenoid valve 7 of inner chamber 4 on delivery pipe 5 and external filter cleaner 6 links to each other, external filter cleaner 6 outer periphery one circle water jacket 9, establish intake pipe 10 on it, outlet pipe 11, they are connected with circulating water cavity on the car, and the air outlet 12 of solenoid valve 7 links to each other with the one-level reduction valve of pressure governor 2 through delivery pipe 13.Through filter cleaner 6 gasifications, petroleum gas after the filtration enters the one-level reduction valve by delivery pipe 13, rising along with one-level reduction valve chamber pressure, diaphragm 17 moves upward, driving lever 18 and spool 16 moves downward, close suction port, petroleum gas then enters the second depressurized valve, the lever 19 of second depressurized valve is set up on solenoid valve 22, and link to each other with reduction valve diaphragm 21, when entering second depressurized valve gas pressure and increase, reduction valve diaphragm 21 moves upward, driving lever 19 and spool 20 moves downward, close suction port, make the air pressure of reduction valve output obtain adjusting, petroleum gas is input to the automotive air intake system by can regulate air valve 24 from pneumatic tube 23.
