Claims

[Scope of utility model registration request]

A valve body 1 having an inlet 10 and an outlet 11 is provided with a valve 2 for communicating the inlet 10 and the outlet 11, and a valve 3 for opening and closing the valve 2.
A rod 30 is integrally provided on the valve 3, and the upper end of the rod 30 projects watertightly onto the upper surface of the valve box main body 1. A case mounting seat 17 is formed so as to surround the case mounting seat 17, and a case 5 having a cylindrical portion 51 on the lower surface side is formed in the case mounting seat 17 through a through hole 51b opened in the bottom surface of the cylindrical portion 51. The upper end of the rod 30 is assembled into the cylindrical portion 51 thereof, and the motor M and the rotating screw 6 rotated by the output shaft m of the motor M are assembled and supported in the case 5. A sliding screw 8 whose inner peripheral side is screwed onto the outer periphery of the rotary screw 6 is fitted into the cylindrical portion 51 so as to be movable up and down while restricting rotation. An electric valve that abuts against the top end.
