Abstract
The utility model provides a gas butterfly valve actuating mechanism which is simple in structure and is sensitive and precise in control. The gas butterfly valve actuating mechanism comprises a frequency modulation motor arranged on a butterfly valve shell, wherein an output shaft of the frequency modulation motor is connected with a rotating shaft for driving a disc type opening-closing piece of a butterfly valve to turn over.
Description
Technical field
The utility model relates to Gas fuel butterfly valve actuator.
Background technique
Butterfly valve is with a kind of valve of opening about disc type open-shut device reciprocating rotating 90 degree, cut out with the regulated fluid passage.For Gas fuel butterfly valve, it is the important valve of the blast tube of control burner.
Originally the linking mechanism be made up of a plurality of connecting rods of the actuator of the Gas fuel butterfly valve of burner drives rotating shaft through linking mechanism and rotates, thereby makes the disc type open-shut device upset of butterfly valve, realize blast tube unlatching, close with gas flow and regulate.
This actuator parts are more, and the location is not very accurate, and it is easy to damage.
Summary of the invention
The purpose of the utility model provides a kind of simple in structure, the sensitive accurate Gas fuel butterfly valve actuator of control.
This Gas fuel butterfly valve actuator comprises a frequency modulation motor that is provided with on the butterfly valve housing, and the output shaft of frequency modulation motor links to each other with the rotating shaft of the disc type open-shut device upset that drives butterfly valve.
Above-mentioned Gas fuel butterfly valve actuator, the output shaft of frequency modulation motor is coaxial with said rotating shaft.
The beneficial effect of the utility model: the utility model is directly installed frequency modulation motor (adjusting color controls) on butterfly valve; The linking mechanism that cancellation connecting rod etc. is formed, by the rotation of frequency modulation motor control rotating shaft, thus the upset of control disc type open-shut device; The utility model is simple and convenient, and control is accurately sensitive.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Combine accompanying drawing that the utility model is done further to describe through embodiment below.
Gas fuel butterfly valve actuator as shown in Figure 1 comprises a frequency modulation motor 2 that is provided with on the butterfly valve housing 1, and the output shaft 3 of frequency modulation motor links to each other with rotating shaft 4, and the passage 6 interior turnover disc type open-shut device 5 that Gas fuel butterfly valve is set are fixedly linked with rotating shaft 4.Rotating shaft 4 is along the radially extension of passage.The output shaft 3 of frequency modulation motor is coaxial with rotating shaft 4.The frequency modulation motor action, rotating shaft is promptly rotated, and the disc type open-shut device promptly overturns, and can open or close passage 6.
