PROBLEM TO BE SOLVED: To provide an agricultural water dividing valve capable of discharging air in a water supply pipe in a closed valve state. ! SOLUTION: An agricultural water dividing valve 1 is equipped with a valve element 20 which opens/closes a valve seat 10 provided at an opening portion of a frame body 2. An air hole 44 penetrating in a vertical direction is provided at the center of a valve element body 22 of the valve element 20, and below the hole, a float valve 70 which vertically movably houses a float valve element 80 formed of a material having smaller specific gravity than water is attached. As a main cock of a water supply pipe to which the water dividing valve 1 is attached is opened in the state where the valve seat 10 is closed, air accumulated in the water supply pipe is pushed out by water and discharged from the air hole 44 in an opened state, and water flows into the water dividing valve 1 at this timing. The float valve element 80 rises with rising of water level in the water dividing valve 1 to automatically close the air hole 44. ! COPYRIGHT: (C)2014,JPO&INPIT
