Abstract
A valve is formed by an intersection of an open ended water supply pipe and a sprinkler outlet pipe. The outlet pipe has a closed end and an outlet end that is adapted for connection to a sprinkler. A cylindrical guide post connected to the closed end extends through the intersection to a proximal portion of the outlet end. A guide assembly is slidably disposed over the guide post. In response to an excessive flow of water through the outlet end, the guide assembly is drawn through the intersection to occlude the outlet end.
Claims12
A valve for preventing an excessive flow of water through an outlet pipe that has an outlet end adapted for connection to a sprinkler and a closed end, comprising:
- a water supply pipe that is integrally connected to said outlet pipe to form an intersection;
- a guide post that is connected to said outlet pipe, said guide post extending through said intersection to a proximal portion of said outlet end;
- and
- a guide assembly that fits slidably over said post, said guide assembly being positioned on said guide post to occlude said outlet pipe in response to a flow rate of said water being greater than a desired flow rate.
