Control method for relay network connection of two gas chambers

Provided is a control method for relay network connection of two gas chambers. The two gas chambers are connected to the same gas pipe network and jointly play gas peak removal, valley filling and pressure stabilization effects, and meanwhile the gas recovery problem during in-turn overhauling of the gas chambers is solved. The control method specifically comprises the following steps of 1 comparing inlet gas pressures of the two gas chambers and defining the near-end chamber and the far-end chamber according to the pressures, 2 comparing resistance values of inlet and outlet pipe networks of the two gas chambers and regarding the larger resistance value as pipe network resistance DeltaP, and 3 setting the pressures of pistons and T-shaped baffles of the two gas chambers according to the principles of the gas inlet chamber and the gas outlet chamber. The relay network connection operation of the two gas chambers is achieved by reasonably setting the pressures of the pistons and T-shaped baffles of the two gas chambers, the problem that the gas chambers are successively established and connected to the network is solved, and the gas buffering and pressure stabilization demands are met. In addition, optional switching between a double-chamber relay operation mode and a single-chamber operation mode can be further performed, and the problem that gas cannot be recovered during gas chamber overhauling is effectively solved.
