When replaced pipe outlet detect natural gas effusion and concentration more than 95% when, sent out by the GPRS module loading thereon
Send end signal to automatic control system, then closed the electrically operated valve of replaced pipeline by control system, displacement completes；
(5) close the connection going out to hold turbine ball valve, removing displacement apparatus and replaced pipeline that valve is connected with displacement apparatus,
Returning to can be to the state of replaced gas supply conduit, you can gone into operation to the formal supply of pipeline；
Total in another kind preferred embodiment of the present utility model, to the flow process of tank body displacement be：
(1) by inlet side turbine ball valve high pressure flexible rubber hose and movable head and the sky of input unit part of the present utility model
Ran Qi gas source pipe UNICOM, will go out to hold the inlet end pipeline phase of turbine ball valve high pressure flexible rubber hose and articulation and replaced tank body
Connection, now tank body admission line should already with former enter source of the gas cut off, meanwhile, connect and start industrial computer and control cabinet；
(2) unload tank base manhole flange, from there evacuated air install the concentration of natural gas detector with GPRS additional；
(3) nominal diameter of replaced tank body inlet end pipeline, computer controls part is inputted to computer controls part
Replaced tank body inlet end pipeline inlet end flow is controlled by the aperture that control cabinet controls motor-operated control valve, that is, insures flow,
Make flow velocity in replaced tank body inlet end pipeline for the natural gas be less than 5 meter per seconds and pressure less than 5kPa, then, open
Open motor-operated control valve and convey natural gas into replaced tank body and enter line replacement；
(4) because the proportion of natural gas is little compared with air, the naturally slow floating of natural gas entering tank body occupies tank body top
Space, simultaneously as air can sink to occupying tank body lower part space and gradually be excreted by manhole；
(5) computer controls part obtains the detection signal of intelligent flow integration meter, calculates reality according to detection signal
Uninterrupted is simultaneously compared with insurance flow, when actual flow exceedes insurance flow, controls Electronic control by control cabinet
Valve reduces flow, conversely, then increasing flow；
(6) concentration of natural gas detector detects to tank base manhole effluent air, when being tested with natural gas
During effusion, that is, show that natural gas has been filled with whole tank body, end signal is sent to automatically controlling by the GPRS module that loads thereon
System, then the electrically operated valve of replaced pipeline is closed by control system, displacement completes；
(7) install tank base manhole flange, close the valve that valve is connected with displacement apparatus, remove displacement apparatus and quilt
The connection of displacement pipeline, returning to can be to the state of replaced gas supply conduit, you can gone into operation to the formal supply of tank body.
