Anti-freezing water valve with optional anti-siphon assembly and water-valve accessories

A water valve, comprising:

• a face plate;
• a receptacle disposed in the face plate and having at least one protrusion each configured to engage a respective at least one groove of a valve-opening-and-water-dispensing device;
• a cavity having a front end in water communication with the receptacle, and having a rear end;
• a valve assembly disposed in the cavity and including a first sealing ring configured to form a watertight seal by urging the first sealing ring against the rear end of the cavity in response to the valve-opening-and-water-dispensing device being absent from the receptacle, the valve assembly configured to allow water to flow into the rear end of the cavity in response to the valve-opening-and-water-dispensing device being disposed in the receptacle;
• and
• an anti-siphon assembly including
• an anti-siphon opening disposed in the face plate,
• at least one anti-siphon tube disposed between the anti-siphon opening and the cavity, and
• a single anti-siphon valve assembly disposed in the opening, positionable beneath the receptacle, configured to allow water in the cavity to drain, due to gravity, out of the anti-siphon assembly in response to the valve-opening-and-water-dispensing device being absent from the receptacle, configured to close in response to a pressure inside of the at least one tube being greater than a pressure outside of the at least one tube, and configured to open in response to a pressure inside of the at least one tube being less than a pressure outside of the at least one tube.

A water valve, comprising:

• a face plate;
• a receptacle disposed in the face plate and having at least one protrusion each configured to engage a respective at least one groove of a valve-opening-and-water-dispensing device;
• a cavity having a front end in water communication with the receptacle, and having a rear end;
• a valve assembly disposed in the cavity and including a first sealing ring configured to form a watertight seal by urging the first sealing ring against the rear end of the cavity in response to the valve-opening-and-water-dispensing device being absent from the receptacle, the valve assembly configured to allow water to flow into the rear end of the cavity in response to the valve-opening-and-water-dispensing device being disposed in the receptacle;
• and
• an anti-siphon assembly including
• an anti-siphon opening disposed in the face plate,
• at least one anti-siphon tube disposed between the anti-siphon opening and the cavity, and
• a single anti-siphon valve assembly disposed in the opening, positionable beneath the receptacle, configured to allow water in the cavity to drain, due to gravity, out of the anti-siphon assembly in response to the valve-opening-and-water-dispensing device being absent from the receptacle, having an inner end facing the tube, having an outer end facing away from the tube, configured to close in response to a pressure at the inner end being greater than a pressure at the outer end, and configured to open in response to a pressure at the inner end being less than a pressure at the outer end.

A structure, comprising:

• a water-distribution system;
• and
• a water valve coupled to the water-distribution system and including
• a face plate,
• a receptacle disposed in the face plate and having at least one protrusion each configured to engage a respective at least one groove of a valve-opening-and-water-dispensing device,
• a cavity having a front end in fluid communication with the receptacle, and having a rear end coupled to, and in fluid communication with, the water-distribution system,
• a valve assembly disposed in the cavity and including a sealing ring configured to form a watertight seal with the rear end of the cavity in response to the valve-opening-and-water-dispensing device being absent from the receptacle, the valve assembly configured to allow water to flow from the water-distribution system into the cavity in response to the valve-opening-and-water-dispensing device being disposed in the receptacle,
• an anti-siphon opening disposed in the face plate beneath the receptacle, and
• an anti-siphon assembly having at least one tube in fluid communication with the cavity and the anti-siphon opening and having one and only one anti-siphon valve assembly that is disposed, at least partially, in the anti-siphon opening and that is configured to allow water in the cavity to drain, due to gravity, out of the anti-siphon assembly via the at least one tube in response to the valve-opening-and-water-dispensing device being absent from the receptacle.

A water valve, comprising:

• a face plate having a receptacle with at least one protrusion each configured to engage a respective at least one groove of a valve-opening-and-water-dispensing device;
• a cavity having a front end in liquid communication with the receptacle, and having a rear end;
• a valve assembly disposed in the cavity, including a sealing ring, and configured
• to form a watertight seal by urging the sealing ring against the rear end of the cavity in response to the valve-opening-and-water-dispensing device being absent from the receptacle, and
• to allow water to flow into the rear end of the cavity in response to the valve-opening-and-water-dispensing device being disposed in the receptacle;
• and
• an anti-siphon assembly including
• an anti-siphon opening in the face plate,
• a tube connecting the cavity to the anti-siphon opening, and
• a single anti-siphon valve assembly that is disposed, at least partially, in the anti-siphon opening.
