Abstract
Disclosed in the invention is a valve actuator comprising a box body. The box body is provided with a drive mechanism; and the drive mechanism is in transmission connection with a valve drive shaft by a main transmission shaft. The main drive shaft is provided with a driving gear engaged with a plurality of driven gears; and each driven gear is provided with a matched valve drive shaft. According to the valve actuator, on the premise that one drive unit is configured, opening and closing of two valves can be controlled synchronously, so that the opening and closing of the valve become synchronous and precise.
Description
Technical field
The present invention relates to a kind of valve actuator.
Background technique
Conventional valves final controlling element, comprise casing, casing is with driving mechanism, driving mechanism is in transmission connection by main drive shaft and valve live axle, a general valve actuator controls the keying of a valve, need the valve of synchronous opening/shutting if there is two or more, then need to configure a valve actuator respectively, two valve actuators realize synchronous opening/shutting by electronics.But, this structure relative complex, and cost is higher, and synchronous accurate not.
Summary of the invention
In view of the deficiency of background technique, technical problem to be solved by this invention is to provide a kind of valve actuator, and manufacture and the cost of material of this valve actuator are lower, and can the keying of the multiple valve of synchronization control more accurately.
For this reason, technological scheme of the present invention is: valve actuator, comprise casing, casing is with driving mechanism, driving mechanism is in transmission connection by main drive shaft and valve live axle, described main driving axle is with actuation gear, and described actuation gear engages with multiple driven gear, and each driven gear is all supporting is provided with valve live axle.
In the present invention, driving mechanism drives main drive shaft, main drive shaft drives actuation gear, the multiple driven gears engaged with it are impelled to rotate, and then the valve drive shaft turns making driven gear supporting, realize a multiple valve of driving mechanism synchronization control thus, the synchronous driving that brings of this mechanical structure is more accurate, and material and manufacture cost lower.
