In order to solve the technical problems, the invention provides a butterfly valve actuator capable of being controlled remotely, which comprises a stainless steel sleeve, a spiral metal wire, a gear plate, a blade, a valve body and a fixing plate. The valve body is of a hollow cylinder structure, and the fixing piece is arranged on the diameter direction of the valve body and is positioned on the inner upper portion of the valve body. The center of the gear piece overlaps with the center of the stationary blade and is located the below of stationary blade and the gear piece with the stationary blade mutually perpendicular, the blade passes through the connector fastening the top of gear piece and with the seamless butt joint of stationary blade, the one end of spiral wire is connected the center of stationary blade and the other end cup joints in the stainless steel sleeve.
The number of the blades is 2, and the blades are semicircular thin sheets.
The blade is movable in an axial direction of the gear plate.
And the PE sleeve is wrapped outside the spiral metal wire.
The length of the spiral metal wire is 0-10 m.

Detailed Description
The present invention will be described in further detail with reference to the drawings and the embodiments, in order to make the objects, technical solutions and advantages of the present invention more apparent.
FIG. 1 is a schematic diagram of the overall structure of a remotely controllable butterfly valve actuator in accordance with an embodiment of the invention. As shown in fig. 1, the remotely controllable butterfly valve actuator provided by the invention comprises a stainless steel sleeve 2, a spiral metal wire 3, a gear plate 5, a blade 6, a valve body 7 and a fixing piece 8. Wherein, the valve body 7 is in a hollow cylinder structure, and the fixing piece 8 is arranged on the diameter direction of the valve body 7 and is positioned at the inner upper part of the valve body 7. The center of the gear plate 5 is overlapped with the center of the fixing plate 8 and is positioned below the fixing plate 8, and the gear plate 5 is perpendicular to the fixing plate 8. The blade 6 is fastened above the gear plate 5 by the connector 1 and is in seamless abutment with the fixing piece 8. One end of the spiral metal wire 3 is connected to the center of the fixing piece 8, and the other end is sleeved in the stainless steel sleeve 2.
Further, the number of the blades 6 is 2, and the blades 6 are semicircular thin pieces. The blade 6 can move along the axial direction of the gear piece 5 to realize the opening and closing of the blade 6, and when the blade 6 is closed, the fixing piece 8 and the blade 6 are in seamless butt joint with the inner edge of the valve body 7, so that the good sealing performance of the butterfly valve actuator is ensured. The PE sleeve 4 is wrapped outside the spiral metal wire 3, and the PE sleeve 4 can effectively protect the spiral metal wire 3 from abrasion in the use process of the spiral metal wire 3, so that the service life of the spiral metal wire 3 is prolonged. The length of the spiral metal wire 3 is 0-10 m, which means that the butterfly valve actuator can be controlled within 10m to realize remote control of the valve.
When the butterfly valve actuator capable of being controlled remotely provided by the invention is used, a screwdriver is extended into a small hole arranged at the bottom end of the stainless steel sleeve 2 until the screwdriver contacts the spiral metal wire 3 and rotates the spiral metal wire 3, the blades 6 are driven by the spiral metal wire 3 to move downwards along the axial direction of the gear piece 5 to open the blades 6, the two blades 6 move simultaneously, and the openings of the two blades 6 are the same at the same time. The opening degree of the blade 6 can be finely adjusted so as to achieve the purpose of controlling the valve with high precision. In this way, the flexible spiral wire 3 controls the opening and closing of the vane 6, and the length of the spiral wire 3 can be changed within a certain range, so as to adjust the valve remotely and with high precision.
In summary, the butterfly valve actuator capable of being controlled remotely provided by the invention is provided with the stainless steel sleeve, the spiral metal wire, the gear plate, the blade, the valve body and the fixing piece, the blade is driven by the spiral metal wire to move downwards along the axial direction of the gear plate to open the blade, and the length of the spiral metal wire can be changed within a certain range, so that the purpose of adjusting the valve remotely and with high precision is achieved.
