Abstract
A liquefied natural gas filler of single pipe filling computation comprises a fluid inlet pipe A, a return-air pipe B, a house holding, a keyboard and a display arranged on the house holding. One end of the fluid inlet pipe A is provided with a fluid inlet interface 1 and the other end is linked with a vacuum tube 11. A stop valve 2, a flowmeter 3, an electromagnetism valve 4, a unilateralism valve 5 and a pressure sensor 6 are connected in turn between the fluid inlet interface 1 and the vacuum tube 11, the end of the vacuum tube 11 being communicated with an air filling gun 10. The utility model is characterized in that one end of the return-air pipe B is a return-air interface 7 and the other end is an air filling gun interface 9, the return-air pipe B being connected with the fluid inlet pipe A behind the stop valve 2 by a safety valve 8. The gas filler of the utility model has the advantages of highly accurate computation, simple structure, low cost and convenient operation.
Description
One, technical field
The utility model belongs to pack into the equipment of container of liquid gas, particularly is used to fill the machine of LNG Liquefied natural gas.
Two, background technique
LNG Liquefied natural gas (LNG) is a kind of clean fuel for vehicle of having promoted the use of both at home and abroad, needs during use to be filled into the automobile-used LNG liquid container from gas station LNG basin with the LNG filling machine.On February 9th, 2005 notice of authorization a patent No. is arranged is the liquefied natural gas aerating machine of ZL200420003405.2, but there is following defective in this part prior art: its more complicated structurally at first, three interfaces are arranged between filling machine and gas station, must introduce three pipelines to filling machine from gas station, be unfavorable for the simplification of piping layout; Secondly, though this patented technology has solved the influence that residual boil-off gas measures flowmeter in the pipeline, the cryogenic gas in the automobile-used LNG liquid container process measures and does not directly get back in the LNG of the gas station basin, so its accuracy of measuring is not good enough.
Three, summary of the invention
At the above-mentioned defective that prior art exists, propose a kind of single tube of meter and fill the metering liquefied natural gas aerating machine, make the simple in structure of it, cost is low, aerating accuracy of measuring height.
Technical solution adopted in the utility model is as follows.
A kind of single tube fills the metering liquefied natural gas aerating machine, includes liquid inlet pipe, muffler, housing and is installed in keyboard and display device on the housing; Be provided with the feed liquor interface at liquid inlet pipe one end, the other end links to each other with vacuum hose, is connected with stop valve, flowmeter, solenoid valve, one-way valve and pressure transducer between feed liquor interface and vacuum hose successively, and the vacuum hose termination is communicated with air filling gun; It is characterized in that: muffler one end is the return-air interface, and the other end is the air filling gun interface; Between the liquid inlet pipe behind muffler and the stop valve, be connected with safety valve.
The single tube of the utility model structure fills the metering liquefied natural gas aerating machine, when being used for refueling system feed liquor interface and return-air interface is communicated with the LNG feed liquor interface and the closed butt joint of return-air interface of gas station respectively.
The utility model filling machine is compared with prior art ZL200420003405.2, and major advantage is: 1) accuracy of measuring height.The utility model filling machine adopts the liquid inlet pipe single tube to fill, and does not have boil-off gas to get back to the LNG of gas station basin in filling process, thereby has avoided the return-air measurement problem, has improved the accuracy of measuring.2) simple in structure, cost is low, and is easy to operate.The utility model filling machine is got rid of the Circulation pipe of prior art and relevant circulating electromagnetic valve, circulation interface, filling machine circulation interface, return-air vacuum hose and return-air rifle thereof, only needs two pipelines to be connected between filling machine and gas station; Owing to adopt single tube to fill, between filling machine and automobile-used LNG liquid container, also has only an interface again; Like this, both simplified piping layout, significantly reduced cost again, operated also easier.
Four, description of drawings
Accompanying drawing is to comprise that the utility model single tube fills the refueling system schematic representation of metering liquefied natural gas aerating machine structure.
In the drawings, 1-feed liquor interface, 2-stop valve, the 3-flowmeter, 4-solenoid valve, 5-one-way valve, the 6-pressure transducer, 7-return-air interface, 8-safety valve, 9-air filling gun interface, 10-air filling gun, 11-vacuum hose, the 12-LNG basin, 13-liquid feed means, a-liquid inlet pipe, the b-muffler, A-filling machine, B-gas station.
Five, embodiment
Further specify the concrete structure of the utility model single tube type metering liquefied natural gas aerating machine and its working principle below in conjunction with accompanying drawing.
A kind of single tube fills the metering liquefied natural gas aerating machine, includes liquid inlet pipe a, muffler b, housing and is installed in keyboard and display device on the housing; Be provided with feed liquor interface 1 at liquid inlet pipe a one end, the other end links to each other with vacuum hose 11, be connected with stop valve 2, flowmeter 3, solenoid valve 4, one-way valve 5 and pressure transducer 6 between feed liquor interface 1 and vacuum hose 11 successively, vacuum hose 11 terminations are communicated with air filling gun 10; It is characterized in that: muffler b one end is a return-air interface 7, and the other end is an air filling gun interface 9; Between the liquid inlet pipe a behind muffler b and the stop valve 2, be connected with safety valve 8.
Its working principle is as follows:
Come out from 12 ends of the LNG basin internal duct that enters filling machine A through liquid feed means 13 and feed liquor interface 1 of LNG; Before aerating, need pipeline is carried out precooling, air filling gun 10 is connected on the air filling gun interface 9, solenoid valve 4 is opened, LNG goes up stop valve 2, flowmeter 3, solenoid valve 4, the one-way valve 5 of serial connection through liquid inlet pipe a, through vacuum hose 11, air filling gun 10, air filling gun interface 9 and return-air interface 7, get back to LNG basin 12 tops at last again; After precooling is finished, air filling gun 10 is connected to automobile-used LNG liquid container filling opening, realize the single tube fair dress liquid feeding of liquid inlet pipe a to automobile-used LNG liquid container, flowmeter 3 is filled into amount of liquid in the automobile-used LNG liquid container with record.
