Patent GB-787201-A (GB)
Abstract: 787,201. Valves. ROBERTSHAW-FULTON CONTROLS CO. June 27,1955 [Oct. 15,1954), No. 18552/55. Class 135. A temperature control system for a water heater having a tank and a main burner comprises a flame failure safety device, a first and a second valve located in series in the gas supply to the burner, each valve being actuated by a thermal means located in the tank which, on its temperature going above a predetermined maximum temperature for the particular part of the tank, moves its valve to cut-off or restrict fuel flow and opens it as the temperature falls below the value, and an over-temperature safety mechanism for locking the second valve closed should the temperature of its thermal means rise to a predetermined high value above the maximum temperature. Burner gas first passes through a combined thermostat and automatic pilot control which may be of the form described in Specification 764,682, in which at least the main burner or both main and pilot burners have their fuel supply cut-off on total flame failure, while the main gas valve of the thermostat is actuated by a rod and tube thermal element located near the base of the water tank. A fluid thermal element located at the top of the tank is connected via capillary tube 72 with a bellows 74 adjustably positioned by a screw 78 and acting through a spring- loaded lever 81, push-button 90, snap-acting mechanism 67 and override mechanism 60 on a spring-loaded valve 54 located in the burner supply pipe 18 between the burner and the combined thermostat and automatic pilot control. The valve loading spring 100 is located between the valve 54 and a flexible diaphragm 94, the centre 98 of which abuts a projection 114 on a spring-loaded lever 102 held in position against the spring by an arm 106 engaging a projection 108 on lever 81. Normally, the valve opens and closes according to the temperature of the thermal element connected to the bellows 74, the projection 108 sliding beneath the arm 106 but not becoming disengaged therefrom. Should the water at the top of the tank and the thermal element become overheated, the bellows 74 allows the valve 54 to snap to its closed position and then expands still further to disengage the projection 108 from the arm 106 and allow the spring 118 to compress the spring 100 and keep the valve closed. The valve may be allowed to open again by pushing a re-set button 120 which moves the arm 106 over projection 108 by means of bevels 110, 112.
