    摘要： A pressure relief device having a housing including an inlet, an outlet, and an inner wall defining a bore connecting the inlet and the outlet. The inlet is in communication with a fluid under pressure in a pressure vessel. The bore includes an inlet portion extending from the inlet toward the outlet, and an outlet portion extending from the outlet toward the inlet. The bore also includes a tapered portion connecting the inlet portion and the outlet portion. The inlet portion has a diameter which is less than the outlet portion's diameter. A plug is located in the bore and movable from a closed position, in which flow of fluid through the bore is blocked, to an open position, in which flow of the fluid through the bore is permitted in response to a pressure differential between the inlet and the outlet.

    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.

    摘要： A combined relief valve and lid structure is provided for pre-mix beverage and syrup containers having a tubular body enclosing a relief port in the lid, an annular valve seat surface about the relief port and raised higher than the lid surface and drain ports extending from the valve seat surface down to the lid surface to enhance drainage of the entire internal portion of the valve body. The relief port is closed by a spring biased poppet and has a biasing spring held in place in the top of the tubular body by a one-way detent and retainer clip arrangement which must be destroyed to remove it from the valve body to gain access to the relief valve poppet. The valve cannot be tampered with unless this retainer clip for the valve spring is destroyed. The retainer clip is ported to permit cleaning steam or other fluid to enter the top of the valve and drain off through the drain ports without accumulation of condensate or residual fluid in the valve. The poppet is basically cylindrical with relieved vertical side portions or flats to enhance drainage and exposure of the valve surface for cleaning.

    摘要： A reciprocating disclike poppet valve is provided with a frustoconical periphery for contact with a cylindrical valve seat which is inclined radially outwards in the direction of flow, the limited angle of inclination insuring that the area of pressure change between the valve and the seat does not increase sufficiently and the effective upstream pressure on the valve does not reduce appreciably from valve closed to valve fully open position to prevent valve chattering.
