Safety and control devices for gas burners and burning appliances
Special requirements pressure regulator
1 Scope
This standard specifies the classification and classification of burners and pressure regulating devices for burning appliances that use urban gas specified in GB/T 13611.
Group, structure and materials, requirements, test methods, inspection rules, signs, installation and operation instructions, packaging, transportation and storage.
This standard applies to the nominal size not greater than DN250 and the maximum inlet pressure not greater than 500kPa, which is used for gas water heaters and gas heating
The following pressure regulating devices for gas burning appliances or burning equipment such as water heaters, gas stoves, gas burners/machines, gas heaters, gas steam boxes, gas boilers.
---Self-operated pressure regulating device;
---Auxiliary energy can be used, and the auxiliary energy is only used to change the outlet pressure setting instead of the pressure regulating device of positive pressure, zero pressure and negative pressure in the control mode.
This standard does not apply to.
--- Pressure regulating devices installed outdoors and exposed to the environment;
---Gas/air ratio adjustment device/system.
