Abstract
A pressure relief device with a permanently attached rupture disk is disclosed. The pressure relief device includes a valve body. The valve body includes an inlet and an outlet defining a flow passage therebetween. A valve mechanism is housed in the valve body and is movable between a closed position where it blocks the flow passage and an open position. A rupture disk configured to burst when exposed to a predetermined pressure is provided. The rupture disk is permanently attached to the valve body to prevent the pressurized fluid from flowing through the flow passage until it bursts. Permanently attaching the rupture disk to the valve body makes them a compact unit to be replaced and discarded together. The rupture disk may be permanently attached to the valve body by welding, soldering, brazing, crimping, or adhesive bonding.
