Pressure relief valve |
摘要 |
A pressure relief valve for a fluid pressure system having a pressure vent. A body is aligned with and in fluid communication with the pressure vent, the body terminating in a cylindrical portion having a circular opening. A bonnet is in axial alignment with the circular opening and a central shaft extends axially within the bonnet. The bonnet is stationary with respect to the body. A shroud, spaced from and entirely surrounding the bonnet, is axially aligned with the bonnet to allow unobstructed fluid flow in a space parallel to the central shaft between the bonnet and the shroud. The shroud is free-standing except for a radially extending flange attachable to the body. A spindle head disk extends radially from the shaft and has a circular edge seatable in the circular opening of the lip.
