In the transmission and distribution system of urban gas pipeline networks, valve chambers are generally located on ring networks or main pipelines with a high-pressure grade and play important roles in gas source allocation, operating condition adjustment, and emergency response. With the improvement of social requirements for the safe supply of urban gas and the upgrade of the automation level in the industry, the control strategy for valve chambers has gradually changed from manual to remote control. However, the remote control of valve chambers involves the linkage and coordination among the SCADA system, remote controller (RTU), remote control actuator, and valve body, which is a systematic project and requires the formulation of a full-life-cycle management strategy to ensure that the remote control function of valve chambers is stable, effective, safe, and reliable. This paper summarized and discussed the corresponding management strategies from three levels: the construction, application, and safety protection of the remote control of valve chambers, aiming to provide reference and practical value for the promotion and application of the remote control technology of valve chambers in the field of urban gas.
