DN40 thermally activated safety device
RST001.04
F / F DN 40 threaded thermal activation safety device, intervention temperature 100 ° C
Simple, automatic and reliable safety devices. With a minimum investment, it is possible to significantly increase the safety level of the gas system, especially to prevent the danger of explosions. In the event of a fire, in fact, the gas leaks from the system feed the flames and can cause explosions if there is a critical accumulation of gas in the rooms. This thermal device intervenes automatically by blocking the gas flow when the temperature of the device reaches 100 ° C and is therefore able to stop the gas leaking, resisting for 30 min. at a temperature of 650 ° C. All this to give the rescuers time to intervene. These are safety devices that are integrated in the shut-off valves and in the meter valves, limiting the overall dimensions and increasing the functionality of the shut-off valve itself, which thus becomes a passive protection device of the system. The devices consist of an external steel body and an internal thermosensitive device. When the external temperature of 95 ° -100 ° C is reached, the metal alloy, which holds the shutter united to the cartridge, melts and the compression force of the spring projects the shutter against the gas passage hole, closing it completely. the
