Installation of fuel gas-fired boiler safety valve safety valve is one of the important requirements of the protection device fuel gas-fired boiler, boiler user is necessary for proper installation of the safety valve. Following small talk to the fuel gas boiler safety valve installation points: (1) greater than the rated 0.5t h fuel gas boiler / evaporator, at least two safety valves installed; equal to or less than the rated evaporation 0.5t / h fuel gas-fired boiler, at least install a safety valve. The separable exit of the economizer, steam superheater outlet of the safety valve must be installed. (2) safety valve should be mounted vertically at the highest position boiler drum, collection tank. Between the valve and the drum or header, not equipped with access to the steam outlet pipe and the valve. (3) have lever-type safety valve means for preventing movement of the self-weight and deviant restriction lever guides the spring loaded safety valve should lift and handle means for preventing movement of the adjustment screw is screwed lightly. (4) The rated steam pressure less than or equal to 3.82MPa boiler safety valve throat diameter of not less than 25mm; the rated steam pressure is greater than 3.82MPa boiler safety valve throat diameter of not less than 20mm. (5) safety valve boiler tubes, which cross-sectional area not less than the cross-sectional area of ​​the valve inlet. If several valves installed together with a short tube directly connected to the drum, short tube passage area not less than 1.25 times the area of ​​all the exhaust valve. (6) safety valve should normally be installed exhaust pipe, exhaust pipe should be through a safe place, and there is sufficient cross-sectional area to ensure the smooth flow of exhaust. Safety valve exhaust pipe at the bottom should be fitted to the safe location of drainage pipe, the exhaust pipe and drainage pipe not allow the installation of the valve.
