摘要： A pressure release apparatus for relieving pressure that may occur within a pipeline due to water hammers or the like. This apparatus is secured to the pipeline directly in line with the pressure wave and consists of a spool piece having an opening therethrough which is selectively biased in the closed position. When pressure within the pipeline is sufficient to overcome this bias, the opening is unblocked thereby permitting such pressure to be released to the atmosphere. A blast shield surrounds this opening so that the sudden release of such pressure will not cause damage to surrounding people or property.
