Abstract
The utility model relates to a valve manual device allowing transmission through a cylindrical gear. The valve manual device comprises an input shaft. A hand wheel assembly is arranged at one end of the input shaft, and a transmission gear is fixed on the end portion of the other end of the input shaft. The cylindrical gear is arranged on the transmission gear in a meshed mode, and the transmission gear can drive the cylindrical gear to rotate. A worm is fixed on the cylindrical gear and can rotate along with the cylindrical gear. A turbine is connected to the worm. A valve connecting device is arranged on the turbine and used for being connected with a valve which needs to be acted on, so that the using state of the valve is controlled through rotation of the hand wheel assembly. In the using process of the valve manual device, through the transmission of the transmission gear and the cylindrical gear, the transmission ratio on the input shaft which is driven by the hand wheel assembly to rotate can be lowered, the transmission is transmitted to the valve connecting device arranged on the turbine, and therefore accurate control over the valve is realized, and a fine adjustment function and an accurate control function on the valve which is acted on can be achieved.
Description
Technical field
The utility model relates to a kind of valve control device, and particularly a kind of can the realization finely tuned and the accurate valve manual operating device of the column gear transmission of control action valve.
Background technique
The control of general valve need be by manually finishing, during manual control valve, and control switch easily, but when needs regulating valve size, manual control usually error can occur, and the wave properties of adjusting is bigger.
The model utility content
The utility model purpose is to provide a kind of can the realization that valve is finely tuned and the accurate valve manual operating device of the column gear transmission of control action in order to overcome the deficiencies in the prior art.
For achieving the above object, the technical solution adopted in the utility model is: a kind of valve manual operating device of column gear transmission, comprise input shaft, and an end of described input shaft is provided with the handwheel assembly, and fixedly there is driving gear the end of the other end; Be engaged with cylindrical gears on the described driving gear, and can drive the cylindrical gears rotation; Worm screw is fixedly arranged on the described cylindrical gears, and described worm screw can be rotated with cylindrical gears; Be connected with turbine on the described worm screw; Described turbine is provided with the valve connection set, in order to connect the valve of required effect, to realize coming by rotation handwheel assembly the use state of control valve.
Preferably, also be provided with Locking Device on the described input shaft, and described Locking Device is arranged on the outside of housing.
Preferably, the side end of described worm screw is provided with positioning plate, and is screwed on worm screw; Described positioning plate is arranged on the outside of cylindrical gears, to prevent cylindrical gears moving in the radial direction described worm screw.
Preferably, described worm screw is arranged in the turbine box that is connected with the valve connection set, and fixes by its rolling bearing that arranges in top and bottom.
Because the utilization of technique scheme, the utility model compared with prior art has following advantage:
The valve manual operating device of column gear transmission described in the utility model, transmission by transmitting gear and cylindrical gears, can reduce by the velocity ratio on the input shaft of handwheel assembly driven rotary, and be delivered to the valve connection set that turbine is provided with, thereby realized the accurate control to valve, and then can reach the fine setting of acting on valve and the function of accurately controlling.
Description of drawings
Below in conjunction with accompanying drawing technical solutions of the utility model are described further:
Wherein: 1, input shaft; 2, handwheel assembly; 3, driving gear; 4, cylindrical gears; 5, worm screw; 6, turbine; 7, valve connection set; 8, Locking Device; 9, housing; 10, positioning plate; 11, screw; 12, turbine box; 13, rolling bearing; 14, keyway; 15, through hole.
Embodiment
The utility model is described in further detail below in conjunction with drawings and the specific embodiments.
The valve manual operating device of column gear transmission described in the utility model is in the process of using, can be connected with the valve of required effect with valve connection set 7, just can realize valve is used the control of state by rotating handwheel assembly 2, and the valve opening and closing that the Locking Device 11 of described setting can be worked as required rotation is during to certain state, input shaft 1 is fixed on the housing 9, prevent that it from rotating because of institute's external action, effectively guaranteed the use state of required Open valve, wherein the positioning action of Locking Device 8 can by its with housing 9 between on corresponding through hole 15 the inserting bolt (not shown) realize fixing.Can carry out mount by the mode that keyway 14 cooperates with the key (not shown) between the valve manual operating device of column gear transmission described in the utility model, its cylindrical gears 4 and worm screw 5; Cylindrical gears 4 can only rotate it with driving gear 3 because it is blocked by the bump of worm screw 5 and positioning plate 10 respectively both sides up and down to direction in its earth's axis simultaneously, has strengthened its stability in use.Transmission by transmitting gear 3 and cylindrical gears 4, reduced by the velocity ratio on the input shaft 1 of handwheel assembly 2 driven rotary, and be delivered to the valve connection set 7 that turbine 6 is provided with, thereby realized the accurate control to valve, and then can reach the fine setting of acting on valve and the function of accurately controlling.
Below only be concrete exemplary applications of the present utility model, protection domain of the present utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technological scheme of formation, all drop within the utility model rights protection scope.
