Abstract
The utility model relates to a valve swiveling gear box with a secondary reduction gear box, which comprises a main box body and a secondary reduction gear box arranged on one side of the main box body; the improvements of the valve swiveling gear box lie in that a vertical shaft sleeve is arranged in the main box body and is connected with the end of a transitional shaft on one side thereof through big and small cone/speed reducing gear pairs; and the bottom end of the main box body adopts a flange structure connected with the valve; an input shaft with one end extending out of the secondary reduction gear box is arranged therein; a handle wheel is in key connection with the end of the input shaft extending out of the secondary reduction gear box; and the end of the input shaft in the secondary reduction gear box is connected with the transitional shaft through the two speed reducing gear pairs. When in use, the flange structure of the main box body is connected with the valve body, and the valve rod in the valve body is connected with the shaft sleeve; and when the hand wheel is rotated, the two speed reducing gear pairs and the cone gear pair drive the shaft sleeve to rotate, thereby driving the valve rod to lead the valve to be opened/closed, and the opening is convenient.
Description
Technical field
The utility model relates to a kind of gear-box, particularly a kind of valve rotary gear box with secondary speed reducer.
Background technique
Valve is the device that makes the media flow in pipe arrangement and the equipment or stop, also controlling its flow, and when valve opening and closing moment was big, hand rotation is effort.
The model utility content
The technical problems to be solved in the utility model provides a kind of many rotary gear boxes of easily Open valve.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of valve rotary gear box with secondary speed reducer, the secondary speed reducer that comprises main box body and be located at main box body one side, its innovative point is: the axle sleeve that is provided with Vertical direction in the described main box body, axle sleeve is connected with the transition axis end of a side by large and small conical surface speed reducing gear pair, and the main box body bottom is and valve body flange connecting structure; Be provided with the input shaft that stretch out the end in the secondary speed reducer, the end key that this input shaft stretches out secondary speed reducer is connected with handwheel, and an end that is positioned at secondary speed reducer is connected with transition axis by two speed reducing gear pairs.
Advantage of the present utility model is: during use, the flange arrangement of main box body is connected with the valve body of valve, valve rod in the valve body is connected with axle sleeve, when rotating handwheel, driving axle sleeve by two speed reducing gear pairs and conical surface gear pair rotates, thereby drive valve rod action the carrying out keying of valve, it is convenient to open.
Description of drawings
Accompanying drawing is the valve rotary gear box structural representation of the secondary speed reducer of the utility model band.
Embodiment
