Description
Technical Field
The utility model discloses a communicating device convenient for repeated inflation and use of a high-pressure gas bottle, and relates to a device convenient for repeated use of the high-pressure gas bottle.
Background
In industrial production, compressed gas is often needed, many compressed gases such as nitrogen are supplied by using high-pressure nitrogen bottles, after the gas supply of the high-pressure nitrogen bottles is finished, the high-pressure nitrogen bottles can only be used once because no special inflating device exists at present, and a great deal of waste is caused in the past, so that a new refilling device needs to be designed to meet the actual production requirements of enterprises.
SUMMERY OF THE UTILITY MODEL
In view of the above, the utility model provides a communication device convenient for repeatedly inflating and using a high-pressure gas cylinder, which can inflate and repeatedly use the high-pressure gas cylinder after deflation is finished, and has good use and popularization values.
A communicating device convenient for repeated inflation of a high-pressure gas cylinder is provided with a guide pipe which is communicated with a pipeline in a front-back mode, the front end of the guide pipe is provided with a first external thread, the rear end of the guide pipe is provided with a second external thread and a second internal thread, an internal thread through hole is formed in the middle of the guide pipe, and the internal thread through hole is communicated with the pipeline which is communicated with the front-back communicated with the guide pipe.
The tail end of the first external thread at the front end of the conduit is provided with an upward raised step for distinguishing the front end and the rear end of the conduit, so that the direction is not reversed when the conduit is used conveniently.
The external thread at the front end of the conduit is provided with a chamfer.
Further, the inner wall of the rear end of the guide pipe is provided with a flared step, and the front end of the step is provided with a second internal thread.
When the gas cylinder is used, a high-pressure gas cylinder to be inflated is in threaded connection with the second internal thread or the second external thread at the rear part of the guide pipe, the barometer is screwed in the internal thread hole in the middle part of the guide pipe, and the first external thread at the front end of the guide pipe is communicated with a high-pressure gas source; and opening a valve on the high-pressure gas cylinder, filling the high-pressure gas source into the high-pressure gas cylinder, closing the valve on the high-pressure gas cylinder when the barometer displays that compressed gas with preset pressure is filled, and disconnecting the high-pressure gas source to finish the inflation of the high-pressure gas cylinder.
The utility model has the advantages of ingenious conception, simple structure, convenient use and good use and popularization value.
Drawings
The utility model will be further explained with reference to the drawings, in which:
fig. 1 is a schematic perspective view of a communication device for facilitating repeated inflation of a high-pressure gas cylinder.
