Abstract
Piercing surge regulator valve for use with a liquid-carrying member. There is a valve body adapted to be connected to the fluid-carrying member in a sealing manner. The valve body comprises a housing and a housing fitting inside of the housing, the housing and housing fitting being movable in relation to each other. There is a bore in the valve body. There is also a container containing a flexible diaphragm therein so as to divide the container into two chambers, one chamber adapted to contain pressurized gas and the other chamber adapted to contain pressurized liquid, the container having a hole whereby the pressurized-liquid chamber communicates with the bore. A piercing element is present in the bore and has a passage therethrough. The housing fitting engages the piercing element, movement of the housing fitting inwardly in relation to the housing causing the piercing element to move in the direction toward the liquid-carrying member. The piercing element is capable of piercing a hole in the liquid-carrying member. Once the piercing surge regulator valve is emplaced on the pipe, water hammer in the pipe can be controlled.
