コントロールバルブ。[Scope of Claim for Utility Model Registration] 1. An inlet, an outlet, a main valve that communicates the inlet and the outlet, a variable pressure chamber, a pressure introduction passage that communicates the inlet and the variable pressure chamber,
A pressure-responsive main valve that opens and closes the main valve opening in response to the pressure in the variable pressure chamber, a pilot valve hole that communicates the variable pressure chamber and the outlet side, and a pilot valve configured at one end of the lever. A float that is elastically biased in the direction of the valve hole to open and close the valve hole, a float chamber that communicates with the outlet side, and a float that is placed freely within the float chamber and rises and falls according to the water level on the outlet side. A toss level control valve is characterized by a toss level control valve that comes into contact with the other end of the lever and operates the lever downward when the lever is lowered. 2. In the utility model registration claim described in paragraph 1, an annular valve seat is formed at the opening end of the pilot valve hole on the outflow side and projects toward the variable pressure chamber, and the pilot valve is disposed within the pilot valve hole. A level control valve characterized in that the pilot valve hole contacts the annular valve seat from the inside. 3 In the utility model registration claim described in paragraph 1, an annular valve seat is formed at the opening end of the pilot valve hole on the outflow side, and the pilot valve extends from the outflow side to the annular valve seat. A level control valve characterized by being configured so as to come into contact with a seat.
