Abstract:
A pressure relief valve includes a lever plate, a first spring, a fitting, and a guide assembly. The fitting has a first side, a second side, and a flange having a rounded end and includes a surface with which a first end of the first spring contacts. The guide assembly has two sides, two concavities, and at least a portion of the guide assembly extends through the opening of the lever plate, the first concavity is formed on the first side of the guide assembly and contacts the fitting flange rounded end, and the second concavity is aligned coaxially with the first concavity. A rounded end of a rod of the diaphragm assembly contacts the second concavity. The second spring is adapted to supply a second force against the diaphragm assembly to move the lever plate in a second direction that is substantially opposite the first direction.
