Claims

[Scope of utility model registration request]

, is connected to the upper operating part body via a pipe, and the inlet, outlet, and drain port are connected to the side from the bottom in order, and the inner part of the valve body, which has a cylinder inside, is connected to the operating part such as a spindle and a rod, etc. A piston that attaches a required number of ring-shaped gaskets moves up and down, and the ring-shaped gaskets come into close contact with two cylinders located adjacent to the top and bottom of the inlet to stop water. In the freezing faucet, the piston is equipped with at least two ring-shaped packings that are in close contact only with the two cylinders, and above the piston there is a ring-shaped packing that is in close contact with at least the cylinder between the outlet and the drain port. At the upper end, connect the above-mentioned Rondo, and at the lower end, position a piston joint that connects the piston so that it can move up and down, and always apply an upward force to the piston with a spring to create a downward pressure chamber adjacent to the outlet. A pressure-reducing antifreeze faucet comprising a communication hole in the piston or valve body that balances the secondary pressure of the piston and opens the piston lower end chamber formed at the lower end of the piston to the atmosphere in the pipe.
