Abstract
In a quick release valve for a sprinkler head, a valve seat includes an annular stop member spaced outwardly from a fluid passage outlet having an annular beveled surface spaced outwardly from the outlet. A sealing member is seated in the valve seat. A resiliently flexible valve disk has a peripheral flange portion which is turned over the sealing member and rests against the beveled surface. The beveled surface prevents outward radial movement of the peripheral flange portion. A rigid, frangible, thermal, responsive element resiliently deflects the valve disk so as to compress the sealing member and seal the outlet.
