And the driving force '4 inch is about the valve drive that can switch the drive of the valve to manual and automatic. [Prior Art] _ Butterfly valve and other valve device valve drive methods are roughly classified into manual and automatic. Automated devices that can be operated remotely or centrally, or actuators for valve actuation, have become increasingly popular with the automation of plant equipment and devices in recent years, and the importance has continued to increase. In the automation of the equipment and equipment, it is not only required to ensure the safety of the machine itself and the ease of maintenance, but also to perform manual operation on the machine side during emergency, maintenance inspection, confirmation, and test operation. In order to meet the above requirements, the automatic valve device is mainly driven by an electric motor, and if necessary, the valve can be manually driven. Therefore, various automatic/manual switching devices have been proposed. But no matter what kind of problem, 冓k is complicated, the use of short dance, or complicated operation. In order to solve such problems, the applicant of the present patent has first proposed the technique # of Patent Document 1. According to the apparatus disclosed in the patent document i, the following advantages can be achieved: by the i-actuator, the automatic and manual methods are used for the movement; and the material is turned off while the manual operation is performed. Work manually to ensure the safety of manual workers. However, when the valve and the brake device have both the manual mechanism and the automatic mechanism, if the use of 5 200804703 requires only the manual mode, the cost will increase and the function will be wasted. In fact, with the difference in plant equipment and equipment, based on the idea of improving safety, there is also a manual door-reading device that is deliberately not automated at a specific location; in this case, it is only necessary that the automatic mechanism department is not provided. A manual valve drive device composed of a manual structure portion. That is to say, 'the current situation is: although the automation of plant equipment and equipment is developing rapidly' and the need for automatic valve devices is increasing, there is no doubt that the need for manual valve devices is also increasing, and the two are respectively Have their own needs. Generally, when new plant equipment and equipment are newly installed, manual and automatic actuators are ordered according to the amount set in advance, but they are often forced to make design changes at the construction site and change actuators accordingly. Demand. It is unavoidable to leave the remaining items on the eve of this I* month. Moreover, after installing various actuators, if it is necessary to replace the manual device mounting position and the automatic device mounting position, the automatic and manual devices must be completely removed, and then the installation work and the adjustment work are performed again. .

Display and confirm the switching operation of the valve. [Embodiment] Hereinafter, a preferred embodiment of the present invention will be described in detail. Referring to Figure 4, (1) 'Basic unit' (2) is an additional unit attached to the base unit as needed. The additional unit is attached to the base unit, and the manual drive mechanism can be reverted to the automatic drive mechanism. The basic unit (1) has a rotatably supported shaft 8 200804703 inside the casing (3), and one end extends to the outside of the casing Ο) (and a drive shaft (4); and is coupled with the drive shaft (4) to transmit the driving force from the outside Driving force transmission mechanism (5) to the valve stem coupling body (6). The operation panel (7) for manual operation is detachably mounted (4) at the tip end portion of the drive shaft (4) extending from the outer casing (7) to the outside. The drive shaft (4) is provided with a keyhole W outside the outer casing (3), and the gear (9) for transmitting the power from the additional unit (7) to the drive shaft (6) can be connected by the valve key (10). When an automatic mechanism is required, the automatic engine driving force transmission mechanism (5) can be easily removed by releasing the connection of the valve key (10) and the gear (9), and has a screw (1) screwed into the drive shaft (4) and in the axial direction of the drive shaft. a movable movable nut (10), a connecting rod f (13) connected to the movable nut (12); the connecting (4) (9) connecting: the valve stem connecting body (6), when the movable nut (10) is driven The shaft (4) of the shaft (4) is rotated by the link arm (1). In the wide-bar coupling body (6), the valve stem is coupled as a whole in the direction of rotation, and the switching operation of the valve by the rotation of the valve stem is called. = driving force transmission mechanism (5) inside the casing (3) as long as it is configured as °: = the driving force transmitted from the external driving force to the driving shaft (4) is transmitted to the stem connecting body inside the peripheral (3) The desired driving force transmission mechanism can be employed without being limited to the above-described mobile screw link arm'. For example, a blade gear mechanism may be employed, which converts the rotation direction of the drive shaft (4) by a mast fixed to the two portions of the drive shaft (4) and a wheel that is sprayed on the mast, and reads 5 . Valve connector (6). Alternatively, a Scotch Y〇ke mechanism can be used which locks the mobile nut to the screw that drives the 200804703 shaft (6) and causes the scotch yoke mechanism to interlock with the mobile nut to drive The rotational power of the shaft (4) is transmitted to the stem coupling body (6). The valve stem connecting body (6) is fixed with a valve closing side restricting body (14) and a valve opening side restricting body (15) defining a rotation angle thereof, and when it touches, the protruding length can be adjusted from the outside of the outer casing (3) When the closing side member (16) and the valve opening side member (17) formed inside the casing (3) are closed, the opening and closing of the valve can be restricted. In Fig. 2, the valve closed state is indicated by a solid line, and the 2-point chain line indicates a valve open state. The valve opening degree is displayed by an opening degree display device (18) provided outside the casing (3), and the opening degree of the valve can be visually confirmed from the outside of the casing (3). The opening degree $, 'page display device can use the opening degree detecting mechanism described later to output an electronic signal or an air signal of the opening degree. The valve stem coupling body (6) includes a cylindrical body (19) that is rotatably and axially disposed to the outer casing (3) substantially perpendicular to the drive shaft (4), and a valve stem is formed at the center of the cylindrical body (19). The connecting hole (2〇) is inserted into the front end of the valve stem to connect the valve stem to the body in the direction of rotation of the cylinder. Here, although the connection hole (2〇) in the figure is a square hole, it is of course not limited to this shape. The additional unit (2) is provided inside the motor case (21) having a slightly l-shaped square box shape, and has the assembled gear (9) and an electric motor for giving the driving force of the gear (9) (22). And a deceleration transmission mechanism (23) for decelerating the rotation of the electric motor (22) and transmitting the rotation to the gear (9). The deceleration transmission mechanism (23)' is composed of a combination of a plurality of conventional gears, and decelerates the rotation of the electric motor (22) to convey the rotation. a motor outer case (2n), a page motor housing portion (24), and a gear housing portion (25) formed to protrude from the motor housing portion (24) into an L-shape, and are integrally formed into a substantially l-shaped case type. At a predetermined position outside the gear housing portion (25), a spring pin 200804703 is fitted with a hole (26) 'a spring pin fitting hole (27) of the outer casing (7) of the card base unit (1). ) Insert 'Connect the base unit (1) to the add-on unit (7) freely. In order to fix the attachment unit to the base unit, on the opposite side of the magazine lock (10), the attachment unit (2) is locked with screws (3) to the fall prevention plate (29) fixed to the basic unit (1). In the illustrated embodiment, the driving force generating mechanism incorporated in the additional unit (7) is an electric motor (22), but another driving force generating mechanism such as air driving may be used to generate the driving force. It is of course also possible to adopt a corresponding other configuration for the driving force transmitting mechanism of the mechanism to the drive shaft (6) of the basic unit (1). 5 to 10 show a modification of the present invention. Instead of the opening degree display device (18) of the above drawings 2 and 2, the opening degree detecting device (31) is attached to the outside of the casing (7) of the base unit (1), and the valve stem is detected. The rotation angle of the body (ie, the valve stem) outputs the valve opening signal 'and controls the additional unit according to the opening signal of the output to drive the force generating mechanism. The opening detection device (31) is not limited as long as it can output an electric signal or an air signal or other desired signal. The valve opening degree detecting means detects the valve opening degree, and controls the automatic driving mechanism based on the opening degree signal to perform the switching operation of the valve, whereby the display, confirmation, or valve switching operation of the valve switching state can be performed remotely. Referring to Figs. 5 to 10, the opening degree detecting means (31) is provided with a substantially square box-shaped casing (32), and a wheel-out shaft extending in the longitudinal direction is rotatably supported in the casing (32). The wheel-out shaft (33)' is coupled to the aforementioned rod connecting body (6) in the rotational direction. For the output shaft (33), two of the closing side and the opening side are fixed: the limiting cam (34), according to the closing side and the opening side of the cam action 11 200804703 The shunt switch (3 5) is disposed in the outer casing (32) Internally, the limit switch (35) is actuated by the limit cam (34) by the rotation of the output shaft that rotates integrally with the valve stem, and the output valve is opened or closed. This output signal is displayed on the open end of the remote ground - the page dial, which can confirm the valve opening at the far end. Further, the operable valve operating panel controls the actuation of the automatic driving force generating mechanism, and the valve can be operated remotely. At the outer end of the output shaft (33) extending outside the outer casing (32), an indication (3 6) ' is attached to visually confirm the valve opening from a position close to the valve device. As shown in Figure 9, the peripherals (32) are inserted into the connecting pins (3 7) and the screws (3 9), which are fixed between the outer casing (?) of the base unit (?). The fixed web (38) is attached to the outer casing (3). [Simple description of the drawing] Fig. 1 ' is an external view of the connection unit and the additional unit.
