Description
Technical field
The present invention relates to a kind of LNG Liquefied natural gas filling device.
Background technique
LNG Liquefied natural gas is called for short LNG Liquefied natural gas.Present LNG Liquefied natural gas filling device does not use the return-air flowmeter, returns large-mindedly in the filling process when vehicle-mounted bottle pressure is high, because the return-air amount can't measure, actual adding amount is few with regard to the numerical value that shows on the ratio panels, can't reach metering accurately.And after filling device stopped filling, air filling gun and the pipeline that adds between the hydraulic control valve can have a certain amount of LNG Liquefied natural gas, if the time long do not annotate, under the LNG Liquefied natural gas normal temperature very easily gasification cause manifold pressure to raise, make pipeline have potential safety hazard.
Summary of the invention
Technical problem to be solved by this invention is: the LNG Liquefied natural gas filling device that a kind of measuring accuracy height, high safety are provided.
In order to solve the problems of the technologies described above, the technical solution used in the present invention is: the LNG Liquefied natural gas filling device, comprise: housing, be arranged on pipeline assembly and control unit in the housing, be arranged on the filling operating component on the housing, pipeline assembly comprises: by the feed liquor interface that is arranged on the housing, the liquid feeding flowmeter, add hydraulic control valve, pressure transmitter, pressure gauge, the aerating flexible pipe, the aerating pipeline that air filling gun is composed in series, by the return-air rifle, the return-air flexible pipe, safety check, be arranged on the return line that the return-air interface on the housing is composed in series successively, be arranged on the precooling pipeline between outlet of liquid feeding flowmeter and the return-air interface by pre-subcooling control valve control, and being arranged on air filling gun return line between air filling gun refluxing opening on the housing and the return-air interface by safety check control, described adding, be provided with a pressure relief pipe of being controlled by safety check between hydraulic control valve outlet end and return-air interface.Be provided with the return-air flowmeter in the described return line.
Advantage of the present invention is: be provided with a pressure relief pipe by safety check control between hydraulic control valve outlet end and return-air interface owing to add; after liquid feeding finishes; air filling gun and add the liquefied natural gas gasifying that the pipeline between the hydraulic control valve has; pipeline pressure will raise; at this moment gas can flow to the return-air interface by safety check through relief pipeline; finally get back to liquefied natural gas (LNG) tank, the liquid feeding pipeline is played a very good protection, improved the safety in utilization of LNG Liquefied natural gas filling device.
Owing on muffler, install back the throughput meter, when in the filling process during vehicle-mounted bottle return-air, the return-air flowmeter can measure, and assembly can go out actual liquid volume added according to the data computation of liquid feeding flowmeter and return-air flowmeter, make metering more accurate, the user's of the liquid feeding of having guaranteed to come interests.
