Embodiment Construction

[0069]Preferred embodiments of the present invention will be described in detail below. Referring to Figures 1-4, (1) is the basic assembly, (2) is the additional assembly added to the basic assembly as necessary, by adding additional assemblies to the basic assembly, the manual drive mechanism can be changed into an automatic drive mechanism. The basic assembly (1) is equipped with a drive shaft (4) that is freely rotatably supported in the housing (3), and one end extends out of the housing (3), and is linked with the drive shaft (4) to transmit the external driving force Drive force transmission mechanism to stem connector (6). The front end portion of the drive shaft (4) extending from the casing (3) to the outside is detachably equipped with an operating handle (7) for applying power by manual operation. The housing (3) of the drive shaft (4) is provided with a keyhole (8) on the outside, which can be connected with the gear of the drive shaft (6) through the lock key (1...

Abstract

To provide a valve drive device formed so that an automization mechanism can be detachably installed in a manual valve drive mechanism without changing the inner structure of the valve drive mechanism and capable of driving a valve either manually and automatically by transmitting a drive force by the drive force generating means of the automization mechanism to the manual valve drive mechanism, and enabling the removal of the installed automization mechanism as required. The manual valve drive mechanism comprises a handle manually imparting a rotating power, a drive shaft rotatablyfitted to a casing and transmitting the rotating power produced by the handle to a drive force transmission mechanism disposed in the casing, and a valve stem connection body for transmitting the drive force transmitted thereto through the drive force transmission mechanism to a valve stem forming the rotating shaft of the valve. The valve drive mechanism is characterized in that the drive force generating means is detachably fitted to one outer part of the casing, the drive force generating means is connected to the drive shaft through a power transmission means, and a drive force by the drive force generating means is transmitted to the valve stem without changing the manual valve drive mechanism so that the valve can be opened and closed.

Description

technical field [0001] The present invention relates to a valve driving device that applies a driving force to a valve stem of a valve device such as a butterfly valve and a ball valve that rotates the valve stem to open and close the valve, and particularly relates to a valve driving device that can switch the driving between manual and automatic. Background technique [0002] The valve driving methods of valve devices such as butterfly valves are roughly divided into manual and automatic methods. Remotely controlled and centrally managed automatic devices or valve drives are used as actuators. In recent years, with the automation and new installation of machinery and equipment, their demand and importance have also increased. In the automation of machinery, equipment, etc., the safety of the machine itself and easy maintenance are required. At the same time, it is necessary to manually operate beside the machine during emergency, inspection after maintenance, confirmation,...
