As shown in Figure 9, start the enriching flow control valve 33 that also is provided with low-pressure fuel gas flows in the can regulate startup enriching passage 12 on the enriching passage 12.
In the utility model, the seat of honour 103 is provided with internal diameter bigger primary air passage 61 and the less secondary air passageways 47 of internal diameter, when the sliding plug 46 of the valve in the throttle control mechanism 10 upwards slided, primary air passage 61 was connected mixed gas outlet 3, in throttle control mechanism 10
When needle Returnning spring 24 resetted, the sliding plug of valve 46 was sealed primary air passage 61; Secondary air passageways 61 can be directly and mixed gas outlet 3 conductings, and idling air supply channel 11 all is connected in the secondary air passageways 47 with startup enriching passage 12.
Control principle of the present utility model can the trend in body 1 illustrate by air and combustion gas.With reference to figure 7 to shown in Figure 14, air enters body 1 by air suction inlet 2, can enter primary air passage 61 and secondary air passageways 47 then, the air that enters in the primary air passage 61 need could flow to mixed gas outlet 3 through throttle control mechanism 10, and the air that enters in the secondary air passageways 47 can directly flow to mixed gas outlet 3.
High-pressure gas enters body by high-pressure gas inlet 4, by entering relief chamber 5 behind first switching mechanism 6, through relief chamber 5 post-decompression low-pressure fuel gas two kinds of trends are arranged, a kind of is by starting enriching passage 12 and enriching flow control valve 33, through the air mixing in the 3rd switching mechanism 13 and the secondary air passageways 47, flow to mixed gas outlet 3 again; Another kind is to flow to second switching mechanism 9 through decompression outlet passageway 7.
Low-pressure fuel gas through second switching mechanism 9 has two kinds of trends again, and a kind of is to flow to throttle control mechanism 10 through main valve air supply channel 8, flows to mixed gas outlet 3 after low-pressure fuel gas by throttle control mechanism 10 and the air mixing in the primary air passage 61; Another kind of trend is by idling air supply channel 11, by the air mixing in idling flow control valve 32 and the secondary air passageways 47, leads to mixed gas outlet 3 more again.
The control principle of first switching mechanism 6 is in the utility model: with reference to figure 7, shown in Figure 8, before the utility model is started working, the sealing gasket 19 of giving vent to anger in second switching mechanism 9 cooperates with the sealing seat 20 of giving vent to anger under the effect of diaphragm return spring 18, and the outlet passageway 7 that will reduce pressure disconnects with main valve air supply channel 8; Feed high-pressure gas by high-pressure gas inlet 4, lever 14 rotates around lever shaft 36 under the pressure effect of high-pressure gas, reduced pressure sealing pad 15 rotates with lever 14 and leaves the seat of honour 103, so high-pressure gas enters into relief chamber 5, force pressure adjusting spring 16 compressions, increase along with gaseous-pressure in the relief chamber 5, pressure adjusting spring 16 resets gradually, and promote lever 14 rotations, when the gaseous-pressure in entering reduction valve 5 equated with the pressure of pressure adjusting spring 16, reduced pressure sealing pad 15 was sealed the high-pressure gas import, so, pressurized gas have been finished decompression process in relief chamber 5, regulate pressure regulation plug screw 37, can obtain the delivery pressure that needs.
The control principle of second switching mechanism 9 in the utility model: with reference to shown in Figure 7, seal membrane 31 tops link to each other with the diaphragm vacuum passage 21 of giving vent to anger because of giving vent to anger, the bottom communicates with atmosphere, when engine operation, the vacuum that the steam-cylinder piston motion produces enters into the top of the seal membrane 31 of giving vent to anger through the diaphragm vacuum passage 21 of giving vent to anger, there is pressure reduction in seal membrane 31 both sides owing to give vent to anger, use hermetic seal diaphragm 31 and drive sealing plug 51 risings, compress diaphragm return spring 18 simultaneously, at this moment, the sealing gasket 19 of giving vent to anger of sealing plug 51 lower ends leaves the sealing seat 20 of giving vent to anger, and second switching mechanism 9 is opened, so decompression outlet passageway 7 is connected with main valve air supply channel 8.
The control principle of throttle control mechanism 10 is in the utility model: with reference to shown in Figure 7, because of throttle control mechanism 10 is connected between mixed gas outlet 3 and the main valve air supply channel 8, when pulling backguy 38, the sliding plug 46 of valve drives valve needle 22 and rises, main valve air supply channel 8 is opened, primary air passage 61 is also opened, and by mixed gas outlet 3 ejections, it is indoor to enter the engine combustion that is attached thereto after combustion gas and the air mixing; Because valve needle 22 is tapered, the sliding plug 46 of valve promotes high more, and the combustion gas increase is many more, and engine power is just big more; Otherwise power is more little.
The control principle of the 3rd switching mechanism 13 in the utility model: with reference to shown in Figure 9, upgrading valve sealing gasket 29 is closed startup enriching passage 12 under the effect of pressure spring 28; When pulling enriching setting sleeve 57, enriching setting sleeve 57 drives enriching valve rods 27 and rises, so open enriching passage 12, low-pressure fuel gas is entered in the secondary air passageways 47 and air mixing by enriching passage 12, is sprayed in the motor by mixed gas outlet 3 then.
In the utility model, regulate the idling flow control valve 32 on the idling air supply channel 11, low-pressure fuel gas enters the flow in the secondary air passageways 47 in the may command idling air supply channel 11; Regulate the enriching flow control valve 33 that starts on the enriching passage 12, low-pressure fuel gas enter the flow in the secondary air passageways 47 in the may command startup enriching passage 12.
Also be provided with pressure measurement plug 73 on the seat of honour 103, pressure measurement plug 73 be connected in the relief chamber 5.
Control procedure of the present utility model is: ato unit, with reference to figure 7 to shown in Figure 9, the vacuum that the cylinder piston motion produces is through the diaphragm vacuum passage 21 of giving vent to anger, enter into seal membrane 31 tops of giving vent to anger, use hermetic seal diaphragm 31 and drive sealing plug 51 risings, second switching mechanism 9 is opened, and the low-pressure fuel gas body that is come by relief chamber 5 streams enters in the main valve air supply channel 8 through decompression outlet passageway 7.At this moment, because of throttle control mechanism 10 is in closed condition, so the low-pressure fuel gas in the main valve air supply channel 8 enters in the idling air supply channel 11, after the certain tolerance of idling flow control valve 32 adjustings, enter in the motor through secondary air passageways 47, mixed gas outlet 3; At this moment, the startup enriching combustion gas that enters in the secondary air passageways 47 through relief chamber 5, startup enriching passage 12 is also entered in the motor by mixed gas outlet 3.
Because throttle control mechanism 10 is not opened, motor carries out work under idling operation.Regulate idling flow control valve 32, can change the state of idling.
The power of motor is by manual operation, and the sliding plug 46 of valve promotes high more, and the combustion gas increase is many more, and engine power is just big more; Otherwise power is more little.
When putting down the sliding plug of valve 46, main valve air supply channel 8 is closed, and motor will move with idling operation.
Behind engine shutdown, owing to there is not vacuum signal, the seal membrane 31 of giving vent to anger is closed decompression outlet passageway 7 under diaphragm return spring 18 effects, and combustion gas is cut off, and combustion gas can not enter in the engine cylinder.
