Abstract
Abstract A combined fill, pressure relief, and bleed valve assembly for pressure vessels includes a valve portion having a valve housing threaded within a threaded bore in the wall of the pressure vessel and mounting a valve member biased to closed position against a valve seat of the housing. The valve member can be unseated to conventionally fill the pressure vessel. A pressure relief and bleed portion includes a second housing having a hollow body threaded exteriorly and interiorly and a head provided with an outlet. A plurality of bleed grooves on the exterior of the body open to the inner end of the body and to the head. A hollow plug is threaded within the body and seats a pressure rupturable diaphragm against the inner surface of the head to close the outlet. The body is threaded into the bore after filling. The inner end of the body seats on the valve housing to close the inner ends of the bleed grooves and the head seats on the wall to close the outer ends of the bleed grooves. An extension of the plug unseats the valve member to permit pressure fluid to flow through the plug to the pressure rupturable diaphragm. A partial unthreading of the body insufficient to disengage the extension from the valve member unseats the inner end of the housing from the valve housing and the head from the pressure vessel wall to permit the bleed grooves to bleed pressure fluid to atmosphere.
