Abstract

1535525 A method of dampening surge pressures in liquid flow lines TII CORP 26 Nov 1975 [9 Dec 1974] 48607/75 Heading B1C In a method of dampening surge pressures in flow lines the flow line 225 through which liquid is supplied is provided with an orifice plate 224 to cause turbulence in the liquid flow the plate causing a vena contracta portion in the liquid at a distance of 0.25 to 0.5 pipe diameter downstream of the orifice plate, the diameter of the orifice being from 0.7 to 0.9 of the diameter of the flow pipe. An amount of gas is then introduced into the flow pipe, the gas flowing through a nozzle 226 the tip 232 of which is located in the vena contracta portion so that gas is dispersed from the tip into the liquid in the flow pipe, the amount of introduced gas being in excess of that required to saturate the liquid and hence dampen the surge pressures thereof. The method is particularly directed to the reduction of water hammer in flow pipes.
