一般産業用自動制御分野で利用されるものである。[Detailed Description of the Invention] [Industrial field of application] The present invention relates to an electrically operated valve for controlling the opening and closing of various fluids such as cold water, hot water, and steam, and particularly for air conditioning pipes, fan coil units, air handling units, etc. In addition to air conditioning equipment, it is used in the field of general industrial automatic control.

（例えば鋳物製）の為、熱伝達が大きい。又、ふたと電
動機との間のガスケットはアスベストパッキンであり、
厚さが1m/m〜2m/mの薄いものであり、断熱効果が不十分
である。[Prior Art] A conventional motor-operated valve will be described.
As disclosed in the full-text specification, etc., a long neck lid is connected to the upper part of the center of the body of the ball valve, and a valve stem penetrates inside the lid, and between the lid and the valve stem. There is known an electric ball valve in which a sealing member is provided, an electric motor portion is connected to an upper portion of the lid via a gasket, and an upper portion of the valve rod is connected to a main shaft of the electric motor portion. in this case,
Since the lid with a long neck was interposed between the electric motor section and the ball valve body, the heat insulating material was easy to wind, but the heat insulating effect was insufficient. That is, since the lid with a long neck is made of a metal material (for example, a casting), the heat transfer is large. Also, the gasket between the lid and the electric motor is asbestos packing,
The thickness is as thin as 1 m / m to 2 m / m, and the heat insulation effect is insufficient.
更に、弁棒が金属棒であり、電動機の主軸（金属製）
と直接連結されているので、熱伝達が直接的に行なわれ
てしまうという欠点があった。Furthermore, the valve rod is a metal rod, and the main shaft of the electric motor (made of metal)
Since it is directly connected to, there is a drawback that heat transfer is directly performed.

得られず、弁棒と電動機の主軸とが偏心したままトルク

動不良が発生するという欠点があった。Further, since a gasket such as asbestos packing is interposed between the lid and the electric motor, the lid and the electric motor main shaft cannot be concentric with each other, and torque is transmitted while the valve rod and the electric motor main shaft are eccentric to each other. However, there is a drawback in that a defective operation may occur due to galling of the rod or torque loss.

この突出部をレンチ等で略90度の範囲に回動させてい
る。この場合の開閉の位置決めは目視で表示に合わせて
おり、90度の位置を正確に出すことが困難であった。In addition, when the electric valve is manually operated before a power failure or before wiring the electric machine, the shaft for manual operation is projected on the upper surface of the electric operating unit.
This protrusion is rotated by a wrench or the like within a range of about 90 degrees. In this case, the opening / closing position was visually aligned with the display, and it was difficult to accurately set the 90-degree position.
なお、機械的ストッパーは、電動操作機内のリミット
スイッチの開閉接点入・切位置に干渉・妨害するので好
ましくなかった。The mechanical stopper is not preferable because it interferes with or interferes with the opening / closing contact opening / closing positions of the limit switch in the electric operating machine.
