In figure: 1 flinger, 2 filling cylinders, 3 parabolic air flues, 4 pressure air flues, 5 contact valves, 6 first check valves, 7 second check valves, 8 firefighting cartridges, 9 add gas injection bar, 10 filling pistons, 11 piston rods, 12 igniters.
Detailed description of the invention
Below in conjunction with accompanying drawing and embodiment, the invention will be further described.
As shown in Figure 1, give the structural representation of fuel gas filling apparatus of the present invention, it is made up of flinger 1, filling cylinder 2, flinger 1 is made up of parabolic air flue 3 and the two pressure air flues 4 being positioned at parabolic air flue both sides, pressure air flue 4 communicates with parabolic air flue 3, is provided with firefighting cartridge 8 in parabolic air flue 3.The inside of filling cylinder 2 is the cavity storing fuel gas, be provided with filling piston 10 in cavity and add gas injection bar 9, the front end adding gas injection bar 9 is provided with the first check valve 6, first check valve 6 is connected, so that the fuel gas of annotating in cylinder 2 is discharged by adding gas injection bar 9, first check valve 6 successively with the rodless cavity of filling cylinder by adding gas injection bar 9.The entrance that the rear end of filling cylinder 2 is provided with the second check valve 7, second check valve 7 is connected with fuel gas feeding pipe.Fuel gas in filling cylinder 2 can only be discharged by the first check valve 6, and the second check valve 7 can only pass into fuel gas in filling cylinder 2.
Shown flinger 1 is provided with the contact valve 5 matched with the first check valve 6, and contact valve 5 all communicates with parabolic air flue 3 and pressure air flue 4; When contact valve 5 stretches in the first check valve 6 and makes, the first check valve 6 can be made and contact valve 5 and all open.Shown in the front end of pressure air flue 4 be also provided with piston rod 11, the end of piston rod 11 is provided with igniter 12, after flinger 1 moves to and makes piston rod 11 be arranged in the position of pressure air flue 4, by igniter 12 ignited flammable gas, realizes the impelling of firefighting cartridge 8.
The course of work of fuel gas filling apparatus of the present invention is:
Flinger 1 moves towards filling cylinder 2 under the drive of drive unit, contact valve 5 is made to contact with the first check valve 6 and open, and by adding the motion of gas injection bar 9 promotion filling piston 10, the air pressure of annotating in cylinder 2 is raised, the high pressure fuel gas of annotating in cylinder 2 is made to enter in pressure air flue 4 and parabolic air flue 3 by adding gas injection bar 9, first check valve 6 successively, realize the quantitative filling of fuel gas, as shown in Figure 2, the structural representation of fuel gas filling apparatus gas of the present invention filling state is given.
