Abstract

822,324. Controlling gas burners. JEAVONS & CO. Ltd., E. E. Jan. 26, 1956 [Jan. 26, 1955], No. 2287/55. Class 75(1) [Also in Group XXIX] A safety device for a burner e.g. as used in a gas fired furnace and having both gas and air supplied to it under pressure,.shuts off the gas supply to the burner on failure or abnormal reduction in pressure of either the gas or air supply and comprises a gas valve 5 fitted .between the gas supply and the burner gas cock (not shown) and controlled by a pressure responsive device such as a diaphragm 8 which is subject to the air main pressure applied to it through an auxiliary valve 18 interposed in an air conduit 11 tapped off from the main air supply upstream of the burner air cock and controlled by a pressure responsive means such as a diaphragm 19 subjected to the gas main pressure between the valve 5 and the burner gas cock to hold the valve 18 open, a manually operable valve 24 by-passing the gas valve 5 between the gas supply and the burner gas cock and a bleed opening 15 in the air conduit 11 between the valve 18 and the diaphragm 8 through which opening there leaks away the residual air pressure acting on the diaphragm 8 when the main air pressure is cut off by closure of valve 18 when the gas supply to the burner fails. If the air supply fails, the pressure is removed from diaphragm 8 and the valve 5 closes followed by closing of valve 18. Diaphragms 10 and 22 form systems for balancing the pressure acting upon the areas of the valves 5, 18 themselves.
