Abstract
The utility model relates to the technical field of steel cylinder auxiliary devices, in particular to a steel cylinder vacuum pumping device which comprises a metal hose, a valve, a three-way pipe and a bent pipe. The metal hose is connected with the valve; the valve is connected with an air outlet through on interface of the three-way pipe; the bent pipe is connected with another interface of the three-way pipe; and a vacuum meter is connected with the upper part of the bent pipe. By connecting the metal hose to the a vacuum pump, residual gas in a steel cylinder can be vacuumized through the vacuum pump, so as to achieve the purpose of thoroughly eliminating the residual gas, and the device is convenient to operate and avoids the occurrence of accidents.
Description
Technical field
The utility model relates to steel cylinder auxiliary device technical field, specifically a kind of steel cylinder vacuum pumping device.
Background technique
Gas cylinder has more or less all retained some residual gases in the steel cylinder after use, clean out if these residual gases are untimely, again will mix and then have influence on new gas the purity of gas after the inflation, some inflammable and explosive gas mixes rear abnormally dangerous, there is potential safety hazard, and have at present a special device gas in the steel cylinder is not found time, a dangerous and bottle residual gas also discharges unclean in the time of the operation of the method for traditional venting.
Therefore, design a kind of steel cylinder vacuum pumping device that can easily residual gas in the steel cylinder be discharged totally and can report the assurance operator safety, just inventor's problem to be solved for above-mentioned situation.
Summary of the invention
The purpose of this utility model provides a kind of steel cylinder vacuum pumping device, and it is simple in structure, and is easy to use, residual gas in the steel cylinder can be discharged clean and can report to guarantee operator safety, has extraordinary use value.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of steel cylinder vacuum pumping device, comprise metallic hose, valve, threeway, bend pipe, described metallic hose is connected with valve, valve is connected with relief opening by threeway, another jointing in threeway is connected with bend pipe, is connected with vacuum gauge above the bend pipe.
The beneficial effects of the utility model are:
1, by adopting the connection by metal hose vacuum pump, can vacuumize in order to reach the purpose of thorough removing residual gas residual gas in the steel cylinder by vacuum pump, and handling safety is simple, has avoided the generation security incident.
Description of drawings
Fig. 1 is the utility model structural representation.
Description of reference numerals: 1-metallic hose; The 2-valve; The 3-threeway; The 4-bleeding point; The 5-vacuum gauge; The 6-bend pipe.
Embodiment
Below in conjunction with specific embodiment, further set forth the utility model, should understand, these embodiments only are used for explanation the utility model and are not used in restriction scope of the present utility model, should understand in addition, after the content of having read the utility model instruction, those skilled in the art can make various changes or modifications the utility model, and these equivalent form of values drop on application appended claims limited range equally.
As shown in Figure 1, a kind of steel cylinder vacuum pumping device of the utility model structural representation, comprise metallic hose 1, valve 2, threeway 3, bend pipe 6, described metallic hose 1 is connected with valve 2, valve 2 is connected with relief opening 4 by threeway 3, another jointing in threeway 3 is connected with bend pipe 6, be connected with vacuum gauge 5 above the bend pipe 6, by adopting metallic hose 1 to connect vacuum pump, can vacuumize residual gas in the steel cylinder in order to reach the purpose of thorough removing residual gas by vacuum pump, and handling safety is simple, avoided the generation security incident, the utility model is waited in use, and relief opening 4 is received on the steel cylinder mouth, starts vacuum pump, residual gas in the steel cylinder is extracted out by metallic hose 1, in vacuum, can observe pressure by vacuum gauge 5 and change, regulate the dynamics that vacuumizes by valve 2, extraordinary practical effect is arranged.
