摘要： A pressure relief valve to balance the pressure between a cargo tank and the ambient atmosphere is described. The valve is so arranged that the velocity of the out flowing gas jet at no time is under a preset value when the valve is in open position. The valve comprises a valve body (2) designed to act against a valve seat (1) located in a structural outlet (5a) from the cargo tank, which valve body (2) is connected to a rod (7) extending into the structural outlet (5a) opening (5). The rod (7) is being supported and guided by a frame structure (6) extending into the structural outlet (5a) opening (5) and fixed to the structural outlet (5a).

摘要： Immediately after attaching a filler cap to a fill opening, a spring raises a valve body and the rise/fall member, so that a laterally outer circumference of a valve body point contacts with plural convex portions of a second side wall, thereby closing the valve portion. In such a state, coming and going of a fluid between a first space S1 and an opening S3 is not allowed. When a pressure in the fuel tank reaches 5 kPa, the fluid rise a first air passage formed in spaces between respective convex portions on the second side wall, passing the valve portion. Rising fluid lowers the valve body to allow discharging an excessive pressure to the exterior of the fuel tank.

摘要： Embodiments of the present disclosure are directed toward a pressure vacuum relief valve and a seal assembly of the pressure vacuum relief valve. The seal assembly includes a ribbed substrate disposed against a flanged seat of the pressure vacuum relief valve. The ribbed substrate includes ribs extending from a base of the ribbed substrate. The seal assembly also includes a pallet coupled to and disposed below the ribbed substrate. The pallet includes a top ring, a bottom ring, and a flexible diaphragm captured between the top ring and the bottom ring. The flexible diaphragm of the pallet is configured to seal against the ribbed substrate in a sealed position. The pallet and ribbed substrate are configured to move together away from the flanged seat when a pressure on a sealed side of the pressure vacuum relief valve exceeds a maximum pressure threshold. The pallet is also configured to pivot open at an angle relative to the sealed position of the pallet when the pressure on the sealed side of the pressure vacuum relief valve falls below a minimum pressure threshold.

摘要： A fluid pressure relief system and method for a pressure vessel or tank (10) having a normal vent (16) with a first pilot operated safety valve (18) and an emergency vent (62) having a second pilot operated safety valve (25). A vapor recovery line (20) is connected to relief valve (18) and collected at a vapor storage container (21). A manway (22) on the pressure vessel (10) shown in FIG. 2 defines the emergency vent (62) and a main valve member (66) has a counterweight (74) thereon to urge main valve member (66) to a seated closed position on nozzle (60). The first pilot operated safety valve (18) for the normal vent (16) is shown in FIG. 7 and has a T-shaped body (142) with a main relief valve member (172) at one end of the body (142) mounted for movement in a generally horizontal direction and controlled by a diaphragm (176) at an opposite end of the body (142).

摘要： A pressure and vacuum relief vent has the stem of each of its pressure and vacuum valves, which are urged to their closed positions by weight, slidably mounted in a bushing of Teflon in a metallic seat ring so that corrosive build up does not occur on the bushing whereby each of the valves is responsive to the desired pressure differential due to weight. Each of the seat rings has a seat insert of Teflon locked in a groove in the seat ring with an epoxy seal between an outer inclined surface of the seat insert and an inner surface of the seat ring.

摘要： A safety-pressure-vacuum relief valve assembly for vehicle fuel tanks and the like which is adapted either to be mounted at an external point on the vehicle and connected to the interior of the tank by a conduit or to be a part of the cap for the conventional tank filler neck. The assembly comprises a fitting having an upwardly facing annular flange area concentric with the axis of the fitting, a circular plate concentrically resting on the flange, an inverted cup providing a peripheral skirt having a concentric and peripherally extending shoulder above the flange, the cup and fitting being secured against axial separation to capture the said plate therebetween, and an annular flexible gasket having an outer peripheral portion gripped between the plate and the shoulder of the cup and an inner peripheral bead engaging the upper surface of the plate normally to close pressure relief openings in the plate. A spring loaded valve plate urges the radially inward portion of the gasket against the upper surface of the plate. The center of the plate is provided with a vacuum valve opening extending therethrough which is normally closed by a vacuum valve member. The fitting is either connected to the interior of the tank by means of a flexible conduit or the fitting is firmly engaged by the skirt of a filler cap outer shell, in which case the fitting provides an opening through which the valve assembly communicates with the interior of the tank.
