Abstract

820,054. Fluid-pressure servomotor-control systems. GAS COUNCIL. June 17, 1957 [March 17, 1956; Sept. 25, 1956], Nos. 5045/56 and 29290/56. Class 135. A gas burner control system wherein the or each burner 1 has an associated thermally controlled valve 9 in a bleed line 8 the gas supply to which is controlled by actuation of the main gas supply cock 2 associated with the burner, the valve closing when its thermal element 10 is heated by the burner or a pilot jet 6, each bleed line being connected to an automatic main supply cut-off valve 11 which closes with pressure increase in the line, and means preventing operation of the cut-off valve when the cock is first turned on. Gas from the governor 5 passes the weep 30 and acts over the whole of the lower side of diaphragm 25 to lift main valve 29 and weight 31 off its seat 28 to stops 32, the top of the diaphragm opening to atmosphere via passage 22. On opening cock 2 gas passes valve 9 and begins to lift a timing diaphragm 14 and attached valve 19 from an opening of passage 22, the air above the diaphragm escaping via a timing vent 15. Should the pilot burner 6 not light within a predetermined time, the valve 9 remains open, bleed gas fully raises diaphragm 14 and attached valve 21 closes passage 22 so that bleed gas passes through orifice 26 and closes valve 29. If the pilot burner lights, a bimetal 10 closes valve 9, gas beneath diaphragm 14 escapes via open valve 19 and diaphragm 14 falls. Cock 2 is then turned to adjust the main burner 1. In a modification, the timing diaphragm is dispensed with and the bleed line leads to the main diaphragm chamber 23 provided with an atmospheric vent. The cock handle is depressed to isolate the bleed line from the supply before opening the pilot and main burner pipes. Should the burners not light, the thermally controlled valve 9 remains open and, when the cock handle is released, bleed gas closes the main diaphragm valve 29. If the burners light, thermal valve 9 closes and the main valve remains open when the cock handle is released. The burner cannot be relighted until all main cocks are closed in order to build up pressure downstream of the automatic valve 11.
