Objective Valve wells in urban gas pipeline network play an important role in adaptability analysis of gas pipeline network, pipeline leakage alarm and emergency rescue. However, the traditional urban valve wells can not satisfy the needs for pipeline flow measurement, pipeline safety monitoring alarm and pipeline parameters collection. Therefore, this study aims to enrich the functions of traditional valve wells and improve the production capacity of the equipment.

Methods Based on the traditional valve well design and combined with the production requirements, this paper proposed a valve well emergency shut-off valve with the functions of flow measurement, information collection, gas concentration detection and so on. Meanwhile, in order to solve the challenges of real-time monitoring, data acquisition, fault alarm, valve position display as well as remote cut-off operation, a valve well information acquisition and control integrated equipment on the basis of SCADA was also introduced in the study.

Results The developed equipment was shown to have the functions of shut-off valve position display, shut-off remote control, leakage alarm, liquid level alarm, data collection and so on.

Conclusions Relying on the Internet and big data platform, the integrated equipment in valve well can realize the remote and intelligent management of urban pipe network.
