摘要： A pressure relief valve for releasing pressure from a system, which pressure relief valve typically includes a valve housing provided on a pressure relief conduit which receives pressure from the system. A valve opening establishes communication between the valve housing and the pressure relief conduit, and a substantially arcuate valve body is pivotally mounted in the valve housing for sealingly and slidably engaging the valve opening. Accordingly, the valve body is capable of pivoting between a first position to close the pressure relief conduit and a second position to open the pressure relief conduit as the valve body slidably traverses the valve opening. A bias mechanism biases the valve body in the closed position in such a manner that the valve body pivots from the closed position to the open position against the bias mechanism and opens the pressure relief conduit, responsive to a threshold pressure of the pressurized fluid impinging against the valve body in the pressure relief conduit.
