The gas outlet of the screw nipple is provided with bellmouth, and the air inlet of the escape pipe, which stretches into, to be arranged in institute
In the bellmouth stated, and seal connection.The setting of bellmouth keeps the cooperation of screw nipple and escape pipe even closer, reinforced pipe
The air-tightness on road.
The supervisor and the branch pipe are carbon manganese steel pipe.Carbon manganese steel pipe has higher intensity and hardness, has
High voltage bearing effect.
The ball valve is ball valve with a scale.The pointer of ball valve with a scale can accurately point out the position of ball valve aperture, side
Just the manual adjusting of ball valve.
Compared with prior art, the utility model has the advantage of：The setting of screw nipple can be by supervisor and outlet
Pipe be connected to, so as to avoid supervisor with escape pipe be directly connected to when due to line size is mismatched caused by pipeline gas leakage；Sealing cap
Setting so that nitrogen in pipeline is flowed only along the direction of escape pipe；The setting of pressure gauge, convenient for the nitrogen in observation supervisor
Throughput, for judging whether nitrogen conveying is normal；The setting of ball valve can effectively control the influx of nitrogen, ensure enough
Nitrogen supply (NS) amount, and can close at any time, it is safer；The setting of more branch pipes, can connect multiple nitrogen cylinders simultaneously, improve
The efficiency of nitrogen displacer gas work；Branch pipe is connected to by the setting of the first gas cylinder connector and the second gas cylinder connector with nitrogen cylinder,
Make nitrogen pass through branch pipe to be connected to be responsible for, the natural gas facility for needing to overhaul is entered finally along escape pipe；The utility model operates
Convenient, displacement is thoroughly and working efficiency is higher.
