CLAIMS
1. A leak stopping sprinkler head, comprising:
a cylindrical hollow body, said hollow body having an upper portion and a lower portion, said lower portion being fluidly connected to a valve body, said upper portion having a spraying nozzle at a top end;
said upper portion having a first predetermined internal diameter and said lower portion having a second, larger predetermined internal diameter;
said valve body comprising an upper connection, a valve seat fluidly connected to said upper connection and a lower connection;
said lower connection fluidly connected to a water supply line;
a hollow regular spheroid, said spheroid having a diameter larger than said first predetermined internal diameter and smaller than said second predetermined diameter, an attachment point on an outer surface and a series of perforations, said perforations permitting water to pass through said spheroid;
a rigid connecting rod, said connecting rod having a first end and a second end and being attached at said first end to said attachment point;
a sealing disk, said sealing disk having a diameter larger than said valve seat, a central connecting point on an upper surface, said connecting point being hingedly attached to said second end of said connecting rod;
said connecting rod being disposed inside of said hollow body and said valve body and sized to hold said sealing disk away from said valve seat when said hollow spheroid is restrained from upward movement by said first predetermined diameter within said cylindrical hollow body; and
wherein any of removal and destruction of said cylindrical hollow body permits said hollow spheroid to be urged upwardly by pressure of water flowing upwardly in said hollow body, said spheroid pulling said rigid connecting rod and said sealing disk upwardly, causing said sealing disk to seat against said valve seat, thereby terminating the flow of water upwardly through said hollow body, said sealing disk being held against said valve seat by water pressure from said water supply line.
2. The leak stopping sprinkler head, as described in Claim 1, wherein said sealing disk further comprises a resilient upper surface, said resilient upper surface providing an improved seal to said bottom end of said sprinkler riser pipe.
3. The leak stopping sprinkler head, as described in Claim 1, wherein said regular spheroid is a sphere.
4. The leak stopping sprinkler head, as described in Claim 1, wherein said sealing disk further comprises a central aperture, said aperture penetrating said disk and being sized and shaped to produce a sound when water flows through said aperture under pressure from said supply line, said sound alerting a user to any of a broken and missing sprinkler head.
5. A leak stopping sprinkler head, comprising:
a hollow cylindrical casing, said casing having a top surface, a central aperture penetrating said top surface, a surrounding vertical wall, a threaded attachment at a lower end of said vertical wall, said threaded attachment connecting said casing to a water supply line;
a sprinkler pipe, said pipe having an upper end, a lower end and having a spray nozzle disposed at said upper end and being sized to fit slidably through said central aperture;
a sealing flange, said flange being disposed about an outer circumference of said sprinkler pipe at a height to limit upward travel of said sprinkler pipe to a first predetermined distance through said central aperture as water pressure from said water supply line urges said sprinkler pipe upwards, said flange bearing against an underside of said top surface of said casing;
a self-closing spring operated valve, said valve being held in an open position by said sprinkler pipe disposed therethrough, said valve controlling flow of water from said water supply line into said casing and said sprinkler pipe; and
wherein said valve moves to a closed position if said sprinkler pipe moves upwardly beyond said first predetermined distance due to any of breakage and removal of either of said casing and said sprinkler pipe, thereby terminating said flow of water from said water supply line.
6. The leak stopping sprinkler head, as described in Claim 5, wherein said valve further comprises:
a sphere, said sphere being pivotally mounted in a spherical seat, said seat being in fluid connection with said water supply line and said casing;
said sphere having a passage therethrough, said passage being sized to fit slidably about said sprinkler pipe;
an elastic member, said member urging said sphere to rotate to a closing position in said spherical seat, thereby terminating said flow of water from said water supply line; and
wherein said sprinkler pipe is disposed through said passage upon mounting of said sprinkler head, thereby holding said valve in an open position, said valve moving to said closing position upon removal of said sprinkler pipe from said passage due to either of breakage and removal of either of said casing and said sprinkler pipe.
7. The leak stopping sprinkler head, as described in Claim 5, wherein said valve further comprises:
a circular seat, said seat being sized to fit slidably about said sprinkler pipe and being in fluid connection with said water supply line and said casing;
a valve door, said valve door being hingedly mounted and sealably disposed adjacent said seat;
a closing spring, said spring urging said valve door toward said seat;
wherein said sprinkler pipe is disposed through said valve door upon mounting of said sprinkler head, thereby holding said valve door in an open position, said valve moving to a closed position upon removal of said sprinkler pipe from said valve door due to either of breakage and removal of either of said casing and said sprinkler pipe.
