Abstract
A sprinkler or water circulating system having a selected number of sprinkler heads, bubblers or the like, each having an associated valve mechanism adapted to effect valve closure upon displacement of the sprinkler head, bubbler, etc., during water flow thereby preventing loss of sprinkler effect and fluid. A normally open spring loaded valve is positioned in a conduit to which the sprinkler head or the like is attached. A stem or rod is positioned in engagement between sprinkler head and valve so that upon displacement the stem may be broken off if of frangible material, or otherwise displaced and the valve is urged into closed position. Upon replacement of the sprinkler head or the like in proper position the rod is replaced to maintain the valve in open position.
Claims7
A water and other fluid distributing system which comprises a fluid supply conduit, one or more subsidiary conduits each having one end affixed to and communicating at its base with said supply conduit and the other end affixed to and communicating with a fluid distributing head, a valve means positioned within each said subsidiary conduit at its base comprising a valve seat and a valve head associated therewith, a valve stem attached to said valvehead at one end and to a compression plate at the other end, a spring surrounding said valve stem positioned between said valve seat and said compression plate, said valve head being maintained in open position during fluid flow to said distributing head with respect to said valve seat while said spring is under compression between said compression plate and said valve seat and in closed position when said compression is removed, a displaceable compression rod positioned concentrically within said subsidiary conduit between and in engagement with the base of said distributing head and said compression plate, the length of said rod being such that said rod and spring are under compression to maintain the valve in open position during water flow whereby disruption or removal of said rod will release compression of said spring and permit closure of said valve head upon said valve seat.
