The protection system can prevent vehicle gas supply devices from fires and explosion to endanger public safety caused by accident gas leakage, reaches the aim of vehicles safely applying gas as fuel, and is applicable to gas-powered vehicles.
Description
Technical field: the utility model relates to the gas leakage fender guard, and particularly a kind of hydrogen, natural gas-powered car gas feeder prevent the accidental release protection system.
Background technology: be used in the hydrogen on the automobile, the protection system that gas plant does not also retrieve gas leakage.
Summary of the invention: the purpose of this utility model is to provide a kind of hydrogen, natural gas-powered car gas feeder to prevent the accidental release protection system; utilize this protection system; can prevent that the automobile gas feeder from meeting accident causes gas leakage and accident to cause the accidents that endanger public security such as fire, blast, reaches automotive safety is made fuel with gas purpose.
Formation of the present utility model: form by gaholder, manual main supply switch, electromagnetic valve main supply switch, flame-retardant device, pressure inductor and mixer, manual main supply switch 17, electromagnetic valve main supply switch 4, first flame-retardant device 5, second flame-retardant device 8, pressure inductor 10, mixer 11 are installed on the air inlet pipe 7 between gaholder 1 and the driving engine 12.
Manually on the main supply switch 17 compression indicator 2 and decompression table 3 are being arranged.
Have first fire-retardant taper hole 16, the first fire-retardant taper holes to be connected with air inlet pipe 7 in first flame-retardant device 5, over against the first fire-retardant taper hole 16 is that the afterbody of first fire-retardant stopple 6, the first fire-retardant stopples is installed the first fire-retardant spring 15; Have second fire-retardant taper hole 14, the second fire-retardant taper holes to be connected with air inlet pipe 7 in second flame-retardant device 8, over against the second fire-retardant taper hole 14 is that the afterbody of second fire-retardant stopple 13, the second fire-retardant stopples is installed the second fire-retardant spring 9.
Mixer 11 comprises accelerator pump and idling pump.
Compared with the prior art; the utility model is simple in structure; easy to use, safety, flame-out as forgetting after the chaufeur temporary term stop; vehicle motor moves under the situation of idling; accident extinguishing causes gas leakage, and this moment, device received electric current on the electrical generator when being zero at the inductor on the electrical generator, and inductor starts signal is passed to the electromagnetic valve main supply switch; the electromagnetic valve main supply switch is promptly closed main valve, plays the actv. protective effect.
As contingencies such as the air feed automobile bump in the process of moving, rolls; cause gas leakage; this moment, pressure inductor began transducing signal to the electromagnetic valve main supply switch under the pressure of setting, and the electromagnetic valve main supply switch is promptly closed main valve, plays the actv. protective effect.
