Abstract
A security valve having a body, a fluid control device, and an internal locking structure. The internal locking structure allows for partial movement of the valve before locking the fluid control device in place. A piping system based on the valve.
Claims16
A locking valve comprising:
- a body having an inlet port and an outlet port;
- a ball, rotatably disposed within an aperture of the body, the ball having a bore through a center, the ball providing fluid communication between the inlet port and the outlet port of the body in an open position, and preventing fluid communication between the inlet port and the outlet port of the body in a closed position;
- an actuator connected to the ball;
- a chamber formed by the body, the chamber being in fluid communication with the aperture of the body;
- a secondary inlet port formed by the body providing fluid communication between the inlet port of the body and the chamber;
- and
- a single piece piston slideably disposed within the chamber, the piston slideable between a first position entirely within the chamber and a second position protruding at least partially into the aperture of the body, the piston positioned within the chamber such that a fluid from the secondary inlet port exerts a force directly on the piston.

A locking water valve comprising:
- a body having an inlet port and an outlet port;
- a ball, rotatably disposed within an aperture of the body, the ball having a bore through a center, the ball providing fluid communication of a quantity of water between the inlet port and the outlet port of the body in an open position, and preventing fluid communication of the quantity of water between the inlet port and the outlet port of the body in a closed position;
- an actuator connected to the ball;
- a chamber formed by the body, the chamber being in fluid communication with the aperture of the body;
- a secondary inlet port formed by the body providing fluid communication between the inlet port of the body and the chamber;
- a piston slideably disposed within the chamber;
- a drain port providing fluid communication between the chamber and an outside of the body of the valve;
- wherein the piston further comprises a plurality of stepped increments on a top face, the plurality of stepped increments constructed and arranged to incrementally protrude into the aperture of the body as the ball is moved from the open position to the closed position;
- wherein a fluid pressure in the chamber urges the piston out of the chamber and into the aperture of the body;
- and
- wherein an inner diameter of the outlet port is greater than an inner diameter of the inlet port.
8 more elements
A home water piping system comprising:
- an inlet pipe;
- a locking valve connected to the inlet pipe, wherein a locking structure of the locking valve is only operational when a fluid in the inlet pipe exerts a pressure on the valve greater than an atmospheric pressure, the locking structure operating only based on the pressure of the fluid in the inlet pipe;
- a water meter, positioned on the inlet pipe in a downstream position from the locking valve;
- and
- wherein the locking valve is moveable from an open position to a closed position, and once in the closed position, the valve is locked until the pressure in the inlet pipe acting on the valve is released at which point the locking structure unlocks the valve.
