摘要
A diaphragm valve module is mounted in the lower end of the outer housing of a pop-up rotor type sprinkler for controlling the flow of water through an inlet in response to actuation of a valve actuator component. A resilient deformable semi-circular snap ring is mounted on top of the module and has a pair of opposing peripheral annular portions. Upon removal of the sprinkler riser, the snap ring can be disengaged from an annular groove formed in the interior wall of the outer housing by manually squeezing the annular portions together. This permits removal of the module for repair or replacement. The annular portions of the snap ring are formed with angled slots that receive projections that extend from the cover of the module to produce a camming movement that uniformly retracts the snap ring out of the annular groove to more readily permit removal of the module.
