This standard specifies the terms, definitions, classification, model, structure, material, requirements, test methods, test rules, marking, label, service instruction, packaging, transportation and storage of shut-off valves and relief valves for the city gas (excluding liquefied petroleum gas) distribution system (hereinafter referred to as slam-shut valves and relief valves).
Shut-off valves in this standard are applicable to gas self shut-off valves which use the city gas (excluding liquefied petroleum gas) as the working medium, and adopt the gas flow through the valve as the driving source, and is provided with an inlet pressure not greater than 4.0MPa, an operating temperature range of -20℃~60℃ and a nominal diameter not greater than DN300.
Relief valves in this standard are applicable to gas self pressure relief valves which use the city gas (excluding liquefied petroleum gas) as the working medium, and adopt the gas flow through the valve as the driving source, and is provided with a set pressure not greater than 0.1MPa, an operating temperature range of -20℃~60℃ and a nominal diameter not greater than DN200.
This standard is not applicable to slam-shut valves and relief valves used for indoor gas system.
