Introduction
In gas appliances and gas appliances, the safety control device is the core component, and the VPS is an important safety for the automation control system.
Part of it plays an important role in ensuring the safety of the whole machine.
The formulation of this standard will improve the technical level of China's gas appliance safety and control, make it in line with international standards, and improve China's gas appliance industry zero.
The standard system of components guarantees the safety of users and is of great significance. At the same time, it also regulates the market, guides design, production and inspection.
For important standards.
Safety and control devices for gas burners and burners
Valve inspection system for special requirements automatic shut-off valve
1 Scope
This standard specifies the use of the gas burners for urban gas and the automatic shut-off valves for combustion appliances specified in GB/T 13611.
Terms and definitions, classifications, structures and materials, requirements, test methods, inspection rules, marking, installation and use
Instructions, packaging, transportation and storage.
This standard is applicable to the maximum working pressure of not more than 500 kPa, for the automatic detection of at least two gas burners and combustion appliances.
A device that leaks between automatic shutoff valves gives a signal when the amount of leakage exceeds the pump detection limit or the pumpless detection setting.
