Claims

[Scope of utility model registration request]

The connecting pipe section C connected to the water supply pipe has a small diameter water passage hole 25.
The main body a, which is integral with the upper end of the connecting pipe part C, has a lower valve chamber 6 with a larger diameter than the circumference recessed in the bottom surface, communicating with the water passage hole 25, and an upper valve chamber 7 in the upper surface. The cap 9 is recessed and
The upper and lower valve chambers 6 and 7 are communicated through a communication hole 8, and the upper valve chamber 7 is provided with a cavity 10 that communicates with the outside. By loosely inserting the valve stem of the lower float valve 22 into the through hole 24 that communicates with the communication hole 8 in the main valve chamber 6, water can be prevented from entering the upper valve chamber 7 when the lower float 22 is supplying water. Intake valve to prevent.
