Scope

This standard specifies the structure, classification, and models of smart self-closing valves for pipeline gas based on Narrowband Internet of Things (NB-IoT) technology (hereinafter referred to as "smart self-closing valves"), as well as the requirements, test methods, inspection rules, marking, user manuals, packaging, transportation, and storage for them.
This standard applies to smart self-closing valves that use NB-IoT technology and are installed on indoor gas pipelines with an operating temperature not exceeding -10℃ to 40℃, a nominal size not exceeding 25 mm, and a design pressure of less than 10 kPa. The applicable media include natural gas, artificial gas, and liquefied petroleum gas.
Note: Unless otherwise specified, the pressure mentioned in this standard refers to the relative atmospheric pressure (gage pressure).
