Abstract
The utility model discloses a portable single-tube LNG filling device which comprises a gas inlet pipe communicated with an LNG source. The tail end of the gas inlet pipe is connected with a gas filling pipe used for being connected with a gas filling hose, and the gas filling pipe is provided with a manual stop valve; and the filling device also comprises an exhaust pipe used for unloading and exhausting gas, the gas inlet pipe and the pipeline of the downstream of the manual stop valve of the gas filling pipe are both communicated with the exhaust pipe through pipelines with safety valves. The gas inlet pipe and the exhaust pipe can be respectively connected with a liquid outlet of an LNG tank car and a vehicle-mounted LNG gas cylinder, and the outlet of the exhaust pipe can be communicated with an air or gas collecting device, thus automatically discharging overpressure LNG liquid or high-pressure fuel entering the gas inlet pipe or the gas filling pipe so as to lead the pipeline of the filling device to be within a safe range of pressure; simultaneously, in the using process, the whole device can realize automatic discharge of gas of the tank car and filling of gas to the vehicle-mounted LNG gas cylinder without any power supply; and the portable single-tube LNG filling device has high safety and simple structure.
Description
Technical field
The utility model relates to the inflator of LNG Liquefied natural gas, especially a kind of portable single tube LNG charging device.
Background technique
At present, the vehicle production producer of gas-fueled vehicles need be to vehicle aerating at any time when producing.And fixedly gas station is arranged at the regular aerating equipment that the automobile that acts as a fuel with LNG Liquefied natural gas (LNG) is set up, portable gas station and supporting filling machine, for accurate measurement and intelligent control, fill the metering liquefied natural gas aerating machine as disclosed single tube among the Chinese patent notification number CN 200949748Y, existing fixing, the LNG charging device of mobile gas station all need adopt automatically controlled measuring apparatus and solenoid valve, the manufacture cost and the safety cost of equipment have been strengthened on the one hand again at this, in addition simultaneously, existing apparatus must irregularly unload gas to storage tank, and then vehicle is carried out aerating.Therefore existing natural gas equipment and LNG charging device thereof the vehicle production producer that all not too is fit to gas-fueled vehicles uses aborning.
The model utility content
The purpose of this utility model is to provide a kind of power supply, portable single tube LNG charging device simple in structure of not needing.
The technical solution of the utility model is: a kind of portable LNG charging device, comprise and be used for the suction tude that is connected with the LNG source of the gas, the suction tude end is connected with and is used for the gas tube that links to each other with air filling gun, it is characterized in that: gas tube is provided with hand stop valve, described charging device also comprises outlet pipe, on the described suction tude, all be connected with outlet pipe by the pipeline that has safety valve on the pipeline in the hand stop valve downstream of gas tube.
Described gas tube has more than two, is parallel to the end of suction tude, is equipped with hand stop valve on the every gas tube, all is communicated with the pipeline that has safety valve between every gas tube and the outlet pipe.
]Described charging device comprises the protection box, connects part in linking to each other between described suction tude, gas tube and the outlet pipe and is installed in the protection box, and the external connection end that is used for linking to each other with other equipment of suction tude, gas tube and outlet pipe all leans out to be protected outside the box.
Described charging device comprises that an end is connected in the flexible pipe on the gas tube air outlet, and the other end of flexible pipe is connected with air filling gun.
Portable single tube LNG charging device of the present utility model, its suction tude, outlet pipe can link to each other with LNG tank car liquid outlet, vehicle-mounted LNG gas cylinder respectively, and its exhaust outlet can lead to atmosphere or gas collecting device, and the LNG liquid or the high-pressure gas of the pressure limit that enters in suction tude or the gas tube are discharged off-load automatically, make the pipeline of charging device be in all the time in the safe pressure range, simultaneously, whole device in use just can realize that tank car unloads gas automatically and to the aerating of vehicle-mounted LNG gas cylinder without any need for power supply, and is safe and simple in structure.
Description of drawings
Fig. 1 is the structural representation of LNG charging device of the present utility model.
Embodiment
As shown in Figure 1; portable LNG charging device specific embodiment of the present utility model; comprise stainless steel protection box 1; be provided with in the stainless steel protection box 1 and be used for the suction tude 2 that is connected with the LNG source of the gas; be parallel to two gas tubes 4 of suction tude 2 ends; the outlet pipe 6 that is used for the off-load venting; be equipped with hand stop valve 5 on the every gas tube 4; all be connected with outlet pipe 6 on the pipeline in hand stop valve 5 downstreams of every gas tube 4, be connected with outlet pipe 6 by the pipeline that has safety valve 10 on the pipeline of suction tude 2 and gas tube 4 connecting place upstreams by the pipeline that has safety valve 7.Connect part in linking to each other between described suction tude 2, gas tube 4 and the outlet pipe 6 and be installed in the protection box 1, the external connection end that is used for linking to each other with other equipment of suction tude 2, gas tube 4 and outlet pipe 6 all leans out to be protected outside the box 1.Every gas tube 4 air outlets all are connected with air filling gun 9 by flexible pipe 8.
The use of the foregoing description of the present utility model: the liquid outlet of suction tude 2 with the tank car that stores LNG liquid linked to each other, after tank car makes the LNG supercharging form certain flow velocity with the LNG supercharging or by immersed pump, by opening hand stop valve 5, make LNG liquid enter vehicle and carry bottle by air filling gun 9.During aerating,, make LNG can be full of vehicle-mounted bottle fast by opening the off-load of vehicle-mounted bottle atmospheric valve.In the routine work; if tank car is not aerating for a long time; tank car liquid outlet pressure limit; safety valve 10 take-offs that link to each other with suction tude 2; from the outlet pipe 6 that safety valve 10 is connected, discharge high-pressure gas or LNG liquid; make the pipeline in the protection box be in all the time in the safe pressure range, inflate in order at any time vehicle being carried bottle, and do not need regularly to lose heart.
