The manual and automatic integral valve operation mechanism is characterized in that a bevel gear wheel (4) is arranged on the connecting shaft (2), the lateral surface of the support frame (3) is provided with a bevel pinion shaft (10) capable of sliding in the axial direction, a bevel pinion (6) is arranged on the bevel pinion shaft (10) and is provided with a first position engaged with the bevel gear wheel (4) and the second position separated from the bevel gear wheel (4), and the hand wheel (5) is arranged at the outer end of the bevel pinion shaft (10). During the installation in the mode, a valve braking device has the sufficient space and can be installed, in addition, the potential safety hazard of workers is eliminated, and the manual and automatic integration of the valve operation mechanism is also realized.
Description
Technical field
The utility model relates to a kind of valve operating mechanism, is specifically related to a kind of manual-automatic integrated valve operating mechanism.
Background technique
Pneumatic motor refers to compressed-air actuated pressure energy is converted to the device of the mechanical energy of rotation.General as the rotating power source of complex appts or machine more.
When pneumatic motor needed manually-operable, traditional way connected a handwheel above running shaft, carry out manually-operable with this handwheel; But this kind mode has shortcoming, namely after the top of running shaft has connected a handwheel, does not just have redundant space to connect a braking device.And when pneumatic motor rotated, handwheel also can follow running shaft to rotate, and at this moment handwheel has the possibility that breaks away from rotatingshaft, and the staff is had certain potential safety hazard.
The model utility content
In order to overcome the deficiency of background technique, the utility model provides a kind of manual-automatic integrated valve operating mechanism, mainly solved the not good problem in valve operating mechanism mounting point, when installing by the manner, the braking device of valve has had enough spaces can install and eliminate staff's potential safety hazard, has also realized the valve operating mechanism manual-automatic integrated.
The technological scheme that the utility model adopts is: a kind of manual-automatic integrated valve operating mechanism, comprise running shaft, coupling shaft, support and handwheel, one end of coupling shaft is connected with running shaft, the other end of coupling shaft is installed in the bottom of support, bevel gear wheel is installed on the coupling shaft, the side of support is equipped with the small coning gear shaft that can slide vertically, small coning gear shaft is provided with bevel pinion, and bevel pinion has the primary importance that is meshed with bevel gear wheel and the second place that is separated with bevel gear wheel; Handwheel is installed in the outer end of small coning gear shaft.
Described small coning gear shaft is provided with two circular grooves, and the distance of two circular grooves is enough to make bevel pinion and bevel gear wheel to break away from fully; The outer side surface of support is provided with back-up ring, and back-up ring is provided with gas manual reverse of direction positioning work piece, and small coning gear shaft passes back-up ring and gas manual reverse of direction positioning work piece can be stuck in the circular groove.
Described gas manual reverse of direction positioning work piece inside is provided with spring.
The beneficial effects of the utility model are: owing to take technique scheme, the braking device of valve to have enough spaces can install and eliminate staff's potential safety hazard, also realized the valve operating mechanism manual-automatic integrated.
Description of drawings
Fig. 1 is structural representation of the present utility model.
1-running shaft among the figure, the 2-coupling shaft, 3-operates support, 4-bevel gear wheel, 5-handwheel, 6-bevel pinion, 7-circular groove, 8-gas manual reverse of direction positioning work piece, 9-spring, 10-small coning gear shaft, 11-back-up ring.
Embodiment
Below in conjunction with accompanying drawing the utility model embodiment is described further:
As shown in Figure 1, a kind of manual-automatic integrated valve operating mechanism, comprise running shaft 1, coupling shaft 2, support 3 and handwheel 5, one end of coupling shaft 2 is connected with running shaft 1, the other end of coupling shaft 2 is installed in the bottom of support 3, bevel gear wheel 4 is installed on the coupling shaft 2, the side of support 3 is equipped with the small coning gear shaft 10 that can slide vertically, small coning gear shaft 10 is provided with bevel pinion 6, and bevel pinion 6 has the primary importance that is meshed with bevel gear wheel 4 and the second place that is separated with bevel gear wheel 4; Handwheel 5 is installed in the outer end of small coning gear shaft 10, when the needs manually-operable, but hand rotation handwheel just, thus the space of running shaft top has been saved in the rotation of driven rotary axle, has also eliminated the potential safety hazard to the staff.
Small coning gear shaft 10 is provided with two circular grooves 7, and the distance of two circular grooves 7 is enough to make bevel pinion 6 and bevel gear wheel 4 to break away from fully; The outer side surface of support 3 is provided with back-up ring 11, back-up ring 11 is provided with gas manual reverse of direction positioning work piece 8, small coning gear shaft 10 passes back-up ring 11 and gas manual reverse of direction positioning work piece 8 can be stuck in the circular groove 7, when gas manual reverse of direction positioning work piece 8 cooperates with the circular groove 7 of gear one end of close bevel pinion 6, bevel pinion 6 is engageable with bevel gear wheel 4, at this moment is manually control; When gas manual reverse of direction positioning work piece 8 cooperated with another circular groove 7, bevel pinion 6 separated with bevel gear wheel 4, at this moment was pneumatic control.So can reach the manual-automatic integrated of valve operating mechanism.
Gas manual reverse of direction positioning work piece 8 inside are provided with spring 9, and spring 9 can make gas manual reverse of direction positioning work piece 8 remain in the circular groove 7, avoid gas manual reverse of direction positioning work piece 8 because vibrating circular groove 7, and the location is reliable.
