Abstract
PURPOSE: A simply constructed and low priced safety device which can prevent the discharge of raw gas when the pilot flame of a pilot burner is put out unexpectedly, by operating an automatic valve in the gas piping by the displacement of a diaphragm valve.
CONSTITUTION: When a gas main pipe 1 is opened and gas is ignited at the tip of the first ignition nozzle 31 of a pilot burner 3, the second ignition nozzle 33 at the tip of an inflammable gas introducing pipe 32 is also ignited immediately and flame is generated. A pressure take-out pipe 6 is provided near the nozzle 31 of said inflammable gas introducing pipe 32, and the pressure in this take-out pipe 6 varies largely between the cases when gas is burning and extinguished. Therefore, the pressure in the pressure take-out pipe 6 and the pressure of a pressure pipe 8 which is taken out near the nozzle 33 and has a small variation between burning time and extinguished time are introduced respectively into rooms separated with the diaphragm 71 of a pressure responding device 7, and an automatic valve 4 is controlled corresponding to the pressure difference between the two pressure values.
