Abstract
The utility model relates to a gas supply device with natural gas as fuel for an automobile, in particular to an improved gas supply device of a natural gas motor truck. The improved gas supply device is characterized in that: more than 2 gas cylinders are connected in series to form a cylinder set, an outlet of each cylinder set is connected with a flow rate safety valve, N gas cylinder sets are combined to connect an N-way joint, and an air inflation/deflation unit is arranged between pipelines connecting the N-way joint with an electromagnetic valve. By adopting the N gas cylinder sets formed through serial connection, the improved gas supply device which adopts the above scheme can solve the problem of gas supply needed by the truck for long-distance driving; in addition, the flow rate safety valve of each cylinder set effectively avoids potential safety hazards caused by overflow or leakage of gas. As a beneficial improvement, the gas supply device in the utility model provides effective technical support for improving the safety, economical efficiency, convenient maintenance and the like of gas supply of the truck.
Description
Technical field
The utility model relates to the natural fuels fuel gas supply device of the automobile that is fuel, particularly about the improved fuel gas supply device of a kind of natural fuels autotruck.
Background technology
For strengthening the protection of environment, be that the automobile pollution of fuel increases sharply with the natural fuels, wherein the vehicle of urban public transport occupies the overwhelming majority.And intercity transport vehicle is because the difficulty of aerating, and then relative populations is less.Be the long-distance transport of realization continual mileage, the measure that existing many employings increase the fuel gas bottle quantity remedies the difficult and inconvenient of aerating.Yet, increase too much gas cylinder because of taking up room and diverting device, and bring the difficulty of aspects such as potential safety hazard and operation.
The utility model content
The purpose of this utility model provides the improved fuel gas supply device of a kind of natural fuels autotruck, and it can allow with the natural fuels is the long-distance transport that the automobile of fuel is realized continual mileage, proposes a kind of safe ready and failure-free fuel gas supply device.
For this reason, adopt following technical scheme to be achieved: the improved fuel gas supply device of a kind of natural fuels autotruck, comprise fuel gas bottle, flow safety valve, electromagnetic valve, pipeline, it is characterized in that the fuel gas bottle more than 2 composes in parallel a bottle group, the outlet of each bottle group connects a flow safety valve, N fuel gas bottle group and road connect a N pass joint, be provided with a charge/discharge gas unit between the pipeline of N pass joint connection electromagnetic valve, the charge/discharge gas unit is by main throttle valve, charge valve and aie escape valve are formed, the N pass joint connects main throttle valve, charge valve is located in the pipeline of N pass joint connection main throttle valve, and aie escape valve is located in the pipeline of main throttle valve connection electromagnetic valve; Be provided with 1 Long-distance Control flow safety valve in the set flow safety valve of N fuel gas bottle group.
Press the fuel gas supply device that this programme is implemented, owing to adopt a plurality of fuel gas bottle groups to compose in parallel, not only solved the required fuel gas supply of vehicle long-distance running, and the set secure flows metered valve actv. of each bottle group potential safety hazard of having avoided overcurrent or leakage because of combustion gas to bring.The utility model is for the safety, the economy that improve the vehicle air feed and be convenient to aspect such as maintenance effective technical support is provided, and is a kind of useful improvement.
Description of drawings
What Fig. 1 showed is to be provided with the gas feeder system schematic of 3 fuel gas bottle groups for embodiment.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
Present embodiment is provided with 3 fuel gas bottle groups 1, being provided with 4 fuel gas bottle 10 in each bottle group constitutes through parallel connection, the outlet of 2 bottle groups wherein connects a flow safety valve 4 respectively, other has the outlet of a bottle group to connect the flow safety valve 2 of a Long-distance Control, so that can realize remote control to safety valve at operator's compartment.3 bottle groups are connected in T-pipe joint 3 through flow safety valve and road respectively, T-pipe joint 3 connects electromagnetic valve 6 by pipeline, for ease of filling/put the node in combustion gas and the minimizing pipeline, in this section pipeline, be provided with a charge/discharge gas unit 5, charge/discharge gas unit 5 is made up of main throttle valve 50, charge valve 51 and aie escape valve 52, T-pipe joint 3 direct connection main throttle valves 50, charge valve 51 is located at T-pipe joint 3 and is connected in the pipeline of main throttle valve 50, and aie escape valve 52 is located at main throttle valve 50 and is connected in the pipeline of electromagnetic valve 6.The utility model also can be provided with N fuel gas bottle group 1, and this moment, N fuel gas bottle group 1 and road connected a N pass joint, and all the other are identical with the scheme of 3 fuel gas bottle groups 1 in the previous embodiment, repeat no more herein.
The combustion gas operational process of present embodiment is such, three fuel gas bottle can be distinguished completely separately to driving engine 8 air feed, combustion gas enters main throttle valve through T-pipe joint, and should close charge valve 51 and aie escape valve 52 this moment, and the electromagnetic valve 6 of combustion gas through opening enters and entering driving engine 8 after gas filter 7 filters.When needs put on the air for fuel gas bottle, should close main throttle valve 50, opening charge valve 51 can put on the air.When exitting as needs, then should close charge valve 51 and electromagnetic valve 6, open aie escape valve 52, combustion gas promptly drains into atmosphere through main throttle valve 50 from aie escape valve 52 by T-pipe joint 3.
