Anti-freezing water valve configured for underground (buried) use and with optional anti-siphon assembly, and water-valve accessories

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, having at least one protrusion each configured to engage a respective at least one groove of a valve opening-and fluid dispensing device, and configured to dispense a fluid, a cavity having a top end in fluid communication with the receptacle, and having a bottom end, a fluid inlet, a valve assembly disposed in the cavity and configured to form a seal between the fluid inlet and the receptacle in response to the valve-opening-and-fluid-dispensing device being absent from the receptacle and to break the seal in response to the valve-opening-and-fluid-dispensing device being disposed in the receptacle;
• and a drain valve assembly having a top end in fluid communication with the bottom end of the cavity, having a bottom end in fluid communication with the fluid inlet, and configured to allow fluid to drain from the bottom end of the cavity in response to the valve opening and fluid dispensing device being absent from the receptacle.

A method, comprising:

• engaging each of at least one spiral groove of a valve opening-and fluid dispensing device with a respective protrusion disposed inside of a receptacle of a fluid valve;
• rotating the valve opening-and fluid dispensing device in a direction that causes the device to move into the receptacle;
• and in response to the valve opening-and fluid dispensing device moving into the receptacle, opening a valve assembly to allow a fluid from a fluid-distribution system to flow into a fluid inlet of the fluid valve, from the fluid inlet toward the receptacle, and out from the valve-opening-and-fluid-dispensing device, and closing a drain valve assembly to form a fluid tight seal between a drain output of the fluid valve and the fluid distribution system.

A method, comprising rotating a valve opening-and fluid dispensing device in a direction that causes the device to move out from a receptacle of a fluid valve, the device having at least one spiral groove each engaged with a respective protrusion of the receptacle;

• and in response to the valve opening-and fluid dispensing device moving out from the receptacle closing a valve assembly to prevent a fluid from a fluid-distribution system from flowing from a fluid inlet of the fluid valve toward the receptacle, and opening a drain valve assembly attached to the fluid inlet to break a fluid tight seal between the receptacle and a drain output of the drain valve assembly.
