Claims (1)
ようにした止水弁の駆動装置において、 止水状態のときに上記モータに直列に抵抗体を
接続する制御回路を設けて、止水状態においては
、他の状態に比較して印加電圧が低下した状態で
、上記モータが弁体を弁座に常時押し付けるよう
にしたことを特徴とする止水弁の駆動装置。[Scope of Claim for Utility Model Registration] In a water stop valve drive device in which a motor drives a valve body in a direction opposite to a valve seat, control for connecting a resistor in series with the motor when the water is in a water stop state. Driving a water stop valve, characterized in that a circuit is provided so that in a water stop state, the applied voltage is lower than in other states, and the motor always presses the valve body against the valve seat. Device.
