Abstract
PURPOSE: To prevent a bladder from being damaged or the like by a method wherein a reducing valve to control pressure into the bladder is controlled by a pressure reducing valve operated by steam pressure into a dome and the steam pressure in the bladder is kept at a constant pressure higher than the steam pressure in the dome.
CONSTITUTION: A compressed air piping 10 regulated by a temperature recording regulator and a piping 14a from the pressure reducing valve 13 are connected respectively to the connecting ports 7a, 8a of reducing valves 7, 8 for steam equipped in pressurized steam pipings 9a, 9b. The pressure reducing valve 13 introduces compressed air having the pressure obtained by applying the repulsive force of a spring 13c regulated by an adjusting screw 13b to the hydraulic force from a syphon 11 from a piping 14 through a piping 14a to the connecting port 8a of the reducing valve 8 for steam. The reducing valve 8 is operated by said compressed air and preheating steam from the piping 9 is adjusted in pressure and this steam is introduced into a bladder 3 through a bag-well 4.
