Abstract: A fire protection sprinkler with a push-in connection includes a sprinkler body having an input orifice for receiving fluid and an output orifice for outputting the fluid, the body having a push-in connection at the input end and a base portion. The push-in connection is adapted to be connected to a pipe fitting by insertion and has a plurality of recesses, a first recess having a first gasket, a second recess having a second gasket, and a third recess having a retaining clip. A frangible element is held in place by a set screw and a stopper. The frangible element is designed to fail at a predetermined temperature to release the stopper. A deflector is positioned on the base portion and configured to direct the output fluid toward the output end, upon activation of the sprinkler by failure of the frangible element at the predetermined temperature.

Abstract: A dry pipe valve includes a main chamber having an input port and an output port, a clapper assembly installed in the main chamber, a pushrod, a pushrod chamber, and a dry valve actuator. The clapper assembly includes a clapper that seals the input port of the main chamber, and a hinged lever that holds the clapper in a closed position or allows the clapper to open. Based on a pressure of a control fluid in the pushrod chamber, the pushrod moves to urge the hinged lever against the clapper to hold the clapper in the closed position, or to release the hinged lever and thereby allow the clapper to open. The dry valve actuator is attached to a housing of the pushrod chamber and controls the pressure of the control fluid in the pushrod chamber.

Abstract: In one example embodiment, a bracket for a sprinkler fitting is provided having a first flange, a second flange connected to the first flange, and a mounting flange connected to at least one of the first and second flanges. The mounting flange may for example be substantially orthogonal to the first and second flanges. One of the first and second flanges has a preferably circular hole formed therethrough, and the other has a polygonal opening formed therethrough and aligned with the circular hole. An adapter having a polygonal end is inserted in the bracket such that the polygonal end aligns with the polygonal opening so as to limit rotation of the adapter with respect to the bracket, the adapter disposing a sprinkler coupled thereto with respect to a finished ceiling surface of a structure.
