Abstract
444,397. Gas governors. PARKINSON & COWAN (GAS METERS), Ltd., and PARKINSON, B. R., Terminal House, Grosvenor Gardens, Westminster. Sept. 19, 1934, No. 26905. [Class 135] A gas governor comprises a diaphragm, supported between plates s and t and carrying a main valve member c, which is acted upon through a hole u in the plate t by the pressure of gas from an inlet e. A calculated orifice d in the diaphragm supplies gas to a pilot governor comprising a spring-loaded diaphragm h with a valve k controlling a passage f in the plate s, from where the gas passes through a duct x to the outlet m. When the outlet pressure falls due to an increase in the demand, the pressure on the diaphragm h falls and the pilot valve k opens further so that a fall in pressure above the main diaphragm results and the higher pressure of the gas from the inlet e acting below the main diaphragm opens the main valve c further to increase the supply. When the pressure rises too high in the outlet the reverse action takes place and the valve c tends to close. The duct x from the pilot governor is taken to a point just at the outlet of the main valve so that an aspiratory effect is produced by the flow of the gas through the main valve on the pilot governor which, on increase in gas flow, causes the pilot valve to open further, which in turn causes a greater opening of the main valve, with a consequent increase in pressure at the outlet with increase of flow. The hole u in the plate t is made of a slightly larger area than the orifice d in the main diaphragm and its function is to prevent hunting. Liquid sealed bells may be used in place of the diaphragms.
