Abstract

To provide a small and space-saving device that can be as compact as possible and can be assembled into equipment, etc., can be arranged in a narrow installation location, and can be used for valves and actuators without machining accuracy and flow path adjustment work. A rotary valve with an actuator that can be easily attached and detached with high precision in a predetermined positional relationship, and can easily confirm the valve opening by ensuring compactness with the necessary minimum number of parts and ensuring excellent visibility Actuator for the rotary valve. The valve body (5) built into the main body (4) is rotated through the valve stem (7), and the valve stem is rotated by the actuator (2). The connection plate (3) is fixed on the outer peripheral top surface (8) of the valve stem shaft side of the main body, and the actuator is mounted on the connection plate, and the valve (1) and the actuator are connected by the connection mechanism (90). The actuator body is provided to be detachable, and the connecting mechanism is composed of a fixing mechanism inserted and removed from a lateral direction intersecting with the axial direction of the valve stem.

Description

technical field [0001] The present invention relates to a rotary valve with an actuator that is excellent in compactness as a small electric valve that can be incorporated into equipment or the like, and an actuator that is integrally mounted on the rotary valve and can be downsized. Background technique [0002] Conventionally, as a rotary valve with an actuator in which an actuator is mounted on a valve, for example, an electric ball valve disclosed in Patent Document 1 is known. Patent Document 1 describes a ball valve in which two legs are extended from the lower part of the electric actuator, and the bolt hole passing through the legs and the protruding part formed on the bonnet of the ball valve pass through the ball valve. A set screw is threaded at the thread to fix the ball valve and the electric actuator. [0003] Patent Document 2 discloses a connection structure in which the valve and the actuator are connected via a yoke member, and a bolt is screwed into the b...
