Abstract
The utility model relates to an electric device for partially turning valves, which belongs to a valve electric device. The utility model has the technical proposal that the electric device for partially turning valves adopts a planetary gear driving structure in a universal dual-gear form, and the upper and the lower ends of an eccentric shaft are respectively provided with matching blocks with the consistent directions of gravity centers. The utility model has the advantage of simple structure and oscillation phenomenon elimination when in use, and enables an electric device and a valve to work in a steady state.
Description
The utility model belongs to a kind of electric device for valve.
Before the utility model is realized, adopt the part turning valve Electric actuator of the planetary pinion drive mechanism of general dual gear form, because of planetary pinion does not have counterweight structure or only in a side counterweight structure is arranged, make in use, when motor drives the eccentric shaft rotation by spur gear, because the gyration center and the planetary gyration center of eccentric shaft have a throw of eccentric (this is that this Gear Planet Transmission structure is necessary), rotate the centrifugal force imbalance of generation, to produce periodic vibration, influence the proper functioning of Electric actuator and valve.
The purpose of this utility model provides a kind of electric device for valve that is used for the part turning valve, thereby has solved the problem that exists in the above-mentioned prior art.
Basic fundamental solution of the present utility model is: at the electric device for valve that is used for the part turning valve of the planetary pinion drive mechanism that adopts general dual gear form, the upper and lower end of eccentric shaft respectively is equipped with the balancing weight of a center of gravity direction unanimity.
Below in conjunction with accompanying drawing a kind of embodiment of the present utility model is elaborated.
Accompanying drawing is the utility model embodiment's a structure facade view.
In the accompanying drawing, the power of motor is passed to the planetary reduction gear structure through pair of straight gear (6), (7), comprise eccentric shaft (1), planetary pinion (2), quiet gear (3), moving gear (4) in this structure, after above-mentioned slowing-down structure slows down, pass to output shaft (5) by moving gear again, and the valve rod that drives valve rotates the open and close of realization valve.
In described planetary both sides, promptly the upper end of eccentric shaft is equipped with one with the key connection and is gone up balancing weight (9), and a following balancing weight (8) is equipped with the key connection in the lower end of eccentric shaft.Axially fixing of described balancing weight with ring washer (10), the center of gravity direction unanimity of two balancing weights, and also opposite and symmetrical with the center of gravity direction of planetary pinion, bearing (11), eccentric shaft, make to form a dynamic balance system on the whole.
The utility model is simple in structure, has eliminated oscillation phenomenon during use, makes Electric actuator and the valve can be a proper functioning under the state stably.
