摘要： A pressure relief device for electrical equipment housing, includes a valve body having a pedestal that projects above a mounting flange and a table on the pedestal that supports a two-stage valve assembly that can be sized in diameter independently of the working area of the flange beneath the table. The design is particularly applicable to retrofit applications for large power distribution equipment with the footprint of the pressure relief device fixed by the design of the equipment housings. The first-stage valve opening can be sized substantially as large as vent openings in the housings and the second-stage valve openings can be sized in the desired relationship with the first-stage opening for optimizing valve performance independently of the constraints imposed by the footprint of the device.

摘要： An enclosure for a pressure relief device, particularly pressure relief devices mounted on electrical equipment housings, is pre-assembled together with the pressure relief device. The enclosure, which provides for temporarily confining and directing fluids discharged from the pressure relief device, is pre-assembled leaving a clearance space so that the pressure relief device can be mounted on the housing with the enclosure system in place. A peripheral shield with an opening for attaching the enclosure to a discharge pipe or other duct work remains rotatable until deliberately secured in place. Components can be shared between the enclosure and the pressure relief device to provide a more efficient and cost effective design.

摘要： Disclosed is a pressure relief valve for attachment to a closed vessel having an opening to vent gas and liquids from the housing should the internal housing pressure rise to unacceptable levels. The pressure relief valve includes a single gasket that seals between a valve disk and a collar disposed about the opening. The gasket is fixed to the collar by a single retaining ring and effects seals with the disk valve in two planes, one seal is in a plane generally parallel to the plane of the opening and a second seal is in a plane generally normal to the plane of the opening. Moreover, the second seal remains in tact for a short time after the first seal is broken to permit the rapid separation of the disk valve from the gasket to vent gas and liquids from the housing.
