(6) After valve 42 is in place, the pressure transmitter 2/49 pressure differential is calculated:
when the pressure difference is more than 0.5Mpa, the bypass valve 44/45 is automatically opened for pressure equalization;
when the pressure difference is less than the limit value of 0.5Mpa, the mutual rotation key valve 46 is automatically opened;
when valve 46 is in position, bypass valve 44/45 is automatically closed.
(7) After the valve 46 is in place, the regulating valve 24 is put into the automatic state and 2000m is set3And h is used as a flow set value, the regulating valve is automatically opened, and when the opening degree of the valve is more than 3%, the pressure regulating branch is judged to be successfully opened.

and in a preset time, if the sub-transmission instantaneous flow in the co-construction station mutual-rotation equipment is greater than the metering lower limit of the flow meter, the execution result is that the mutual rotation is successful, otherwise, the mutual rotation is failed.
In the above example, when the execution is completed (4) (5) (6) (7) and the instantaneous flow rate of the flow meter 14 is greater than the upper limit of the range of 20% of the flow meter, it is judged that "switching of the 1# line to the 2# line for switching to the 3# line for switching to the 1# line is successful", and the flow switching control process is ended. If the switching is not completed after 10 minutes, (8), it is determined that "switching from the 1# pipeline to the 2# pipeline to the 3# pipeline to the 1# pipeline fails", and the process switching control process is ended.
308. And outputting mutual conversion state prompt information based on the execution result.
The prompt message is used to prompt the user.
In the execution of the steps 301-308, if it is necessary to shut down the execution, the operator can input a reset signal to execute the following step 309.
309. Based on the reset signal, the step being executed is stopped.
