Abstract

957,472. Pressure-relieving devices. COMMISSARIAT A L'ENERGIE ATOMIQUE. April 13, 1961 [April 29, 1960], No. 13315/61. Heading F2V. A device for maintaining a given pressure in a water pipe 3, consists of a tank 1 connected by a tube 2 to the pipe 3, which tube extends beyond the maximum water level Nm and embodies orifices 4 and a deflector 5. Metal grids 7 are disposed between the upper end 6 of the tube and the maximum water level Nm. Electrical heating coils 8 at the bottom of the tank maintain the water at saturation temperature. In normal operation the tank contains a given water volume, the free surface N being in contact with saturated steam in the upper part of the tank so providing a given pressure balance. Any decrease in the water volume in the pipe 3 is made up by discharge from the tank via the orifices 4, the falling level in the tank resulting in a decreased steam pressure which causes evaporation and so restores the pressure balance, the energy being provided by the coils 8. An increase in the water volume in the pipe 3 causes water to be supplied to the tank largely through the upper end 6 of the tube 2, only a small fraction entering the tank via the orifices 4; the water jet at the end 6 is dispersed by the deflector 5 whilst the grids 7 keep the water droplets in suspension thereby increasing the water-steam exchange surface which results in rapid condensation of the steam and a restoration of the pressure balance. If the volume increase in the pipe 3 is small the water enters the tank through the orifices 4 only. In a modification, the introduction of water into the tank takes place through an external tube opening laterally into the tank above the maximum water level; a short tube incorporating a pair of orifices also enters the lower part of the tank from the water pipe. The inside walls of the tank may be covered by a heat screen and honeycomb guide vanes may be associated with the grids to reduce movement of the free surface. The orifices may be replaced by valves.
