By adopting the utility model, the manual operation range of the crank is extended by the control mechanism with long strip shape, and the gear rotates by the meshing structure of the gear and the rack, so that the control mechanism can move in the length direction, and the crank is driven to slide in the movable frame, thereby the crank rotates, and finally the connection mode of the ball valve is adjusted; the adjusting mode has a simple structure and is convenient to adjust.
Description
Technical Field
The utility model relates to a ball valve field, especially a ball valve operating device.
Background
The ball valve is widely applied to industries such as petroleum refining, long-distance pipelines, chemical industry, papermaking, pharmacy, water conservancy, electric power, municipal administration, steel and the like, and plays a significant role in national economy. It has the action of rotating 90 degrees, the cock body is a sphere and has a circular through hole or a channel passing through the axis.
The ball valve is mainly used for cutting off, distributing and changing the flow direction of a medium in a pipeline, and can be closed tightly only by rotating 90 degrees and a small rotating moment. However, when the ball valve is installed at a high place, a ladder is needed to perform manual adjustment operation, and the operation in the mode is inconvenient and has potential safety hazards.
Disclosure of Invention
The utility model aims to provide a: the ball valve operating mechanism convenient to adjust is provided for solving the problem that the ball valve installed at a high place in the prior art is inconvenient to adjust.
In order to realize the purpose of the utility model, the utility model provides a following technical scheme:
a ball valve operating mechanism comprises a control mechanism and a ball valve, wherein a valve rod of the ball valve is connected with a crank; the control mechanism is provided with a strip-shaped moving frame and forms a crank pin structure through the moving frame and the crank; the control mechanism is provided with a rack in the length direction, the rack and the movable frame are in a T-shaped structure, and the rack is meshed with a gear; the crank can rotate 90 degrees under the driving of the moving frame.
By adopting the technical scheme, the utility model discloses, through the control mechanism of rectangular shape, prolonged the manual operation scope of crank, through the meshing structure of rack and pinion, when making the gear rotate, can realize the motion of control mechanism in length direction, and then drive the crank and slide in moving the frame, thereby make the crank rotate, finally make the connected mode of ball valve adjusted; the adjusting mode has a simple structure and is convenient to adjust.
Further, the length direction of the movable frame is perpendicular to the movement direction of the control mechanism, and the width of the movable frame is larger than the diameter of the clamping position of the crank. The width of the movable frame is larger than the diameter of the clamping position of the crank, so that the crank can move in the movable frame conveniently.
Furthermore, a gear and a bearing base are respectively arranged on two sides of the rack, the rack is positioned in a guide groove formed in the bearing base, and the rack and the bearing base form a guide rail pair structure; the gear is rotationally fixed on the bearing base and is axially connected with a shaking handle. Wave the handle through setting up in gear shaft, wave the handle through the rotation and then can make gear revolve, and then drive the rack and move in the guide slot to drive and remove frame and crank motion, and then adjust the connected mode of ball valve, it is convenient to adjust.
Further, the rack passes through the connecting rod and links to each other with removing the frame, and the uide bushing is worn to be equipped with by the connecting rod. The position of the guide sleeve is fixed, the moving direction of the connecting rod is positioned, and the connecting rod is prevented from deviating.
To sum up, owing to adopted above-mentioned technical scheme, the beneficial effects of the utility model are that: the manual operation range of the crank is prolonged through the strip-shaped control mechanism, and when the gear rotates through the meshing structure of the gear and the rack, the control mechanism can move in the length direction, so that the crank is driven to slide in the moving frame, the crank rotates, and finally the connection mode of the ball valve is adjusted; the adjusting mode has a simple structure and is convenient to adjust.
