Abstract

884,169. Fluid-pressure servomotor-control systems. SULZER FRERES S.A. Oct. 3, 1960 [Oct. 16, 1959], No. 33916/60. Class 135. [Also in Group XIII] In a steam power plant, Fig. 1, in which live steam, leading from an evaporator 1 and a superheater 2 through a pipe 3 to a turbine 4, can be shunted to a condenser 8 through a bypass pipe 16 having a valve 18 controlled by a signal which is derived from the rate of change of pressure (dp/dt) of the live steam (see Group XIII), the by-pass valve 18<SP>1</SP> as shown in a modification, Fig. 2, is varied according to the load characteristics of the steam generator and is also responsive to excess rises in steam pressure. A piston valve 43, with adjustable hand wheel loading, is connected to the diaphragm 41 of a pressure difference sensing unit 40 having its two chambers in communication respectively with a pressure storage chamber 27<SP>1</SP>, connected by a pipe 25<SP>1</SP> with a valve 26<SP>1</SP> to the by-pass 16, and also with the latter by a pipe 34<SP>1</SP>. A pressure medium is supplied through a pipe 46 to the cylinder of the piston valve 43 which, when there is a sudden rise in steam pressure, allows the pressure medium to flow through a pipe 47 to a servo-piston 48 connected to the valve 18<SP>1</SP>. A pressuresensing unit 50, responsive to limit pressure, operates a piston valve 53 which is supplied through a pipe 56 with a pressure medium and is connected by a pipe 57 to the pipe 47 leading to the servo-piston 48. The cylinder of the latter is fitted with a pressure medium discharge pipe 58 having a throttle 59. The throttle valve 26<SP>1</SP> is connected by a spindle 49 to a load controller, not shown, which varies the crosssection of the valve in dependence upon the load of the generator and is also connected to a pipe 54 leading to the chamber of the pressuresensing unit remote from the pipe 34<SP>11</SP>.
