Example (1)

Referring to fig. 1 to 3, the utility model provides a side-mounted window mechanism of an electric actuator of an angular travel valve, which is provided with a valve electric actuator box body 1; the inner cavity of the valve electric actuator box body 1 is provided with a stroke rotating shaft 2 arranged horizontally and a spindle 3 arranged vertically, the stroke rotating shaft 2 corresponds to an electric box cover window 4, and the electric box cover window 4 is positioned on the side of the valve electric actuator box body 1; the stroke rotating shaft 2 is connected with a first bevel gear 21, the main shaft 3 is connected with a second bevel gear 31, and the first bevel gear 21 is meshed with the second bevel gear 31. The electrical box cover window 4 is used for observing the position of a valve switch, and the valve switch comprises a pointer 81 and a valve opening indicator 82. The stroke rotating shaft 2 is rotatably connected with a pointer 81, and the pointer 81 is matched with a valve opening indicator 82. The first bevel gear 21 and the second bevel gear 31 are both 45 ° bevel gears, and 90 ° rotation is performed by the two 45 ° bevel gears so that the stroke rotation axis 2 can be disposed parallel to the horizontal plane. The part of the stroke rotating shaft 2 is arranged in the electric box cover window 4, the stroke rotating shaft 2 is connected with a pointer 81 in a rotating mode, and the pointer 81 is matched with a valve opening indicator 82, so that field personnel can observe the valve opening and closing position displayed in the electric box cover window 4 at the high position on the side face of the valve electric actuator box body 1.

Example (2)

The spindle 3 is not 100% inhibited from moving in place when driven to rotate, except for spinning, and undergoes a slight displacement in vertical height, such as a slight displacement in an upward direction. At this time, the spindle 3 drives the second bevel gear 31 to extrude toward the first bevel gear 21, so that the teeth of the second bevel gear 31 and the first bevel gear 21 are easily damaged by extrusion. As a modified embodiment, the spindle 3 is provided with a spring mounting cavity 51, the spring mounting cavity 51 is provided with a spring 52, and the spring 52 is elastically connected to the second bevel gear 31. When the second bevel gear 31 is slightly displaced upwards, the second bevel gear 31 and the first bevel gear 21 are subjected to overlarge extrusion force, at this time, the second bevel gear 31 simultaneously gives the extrusion force of the spring 52, the spring 52 retracts after being stressed, the second bevel gear 31 is driven to slightly displace in the direction away from the first bevel gear 21 (namely downwards), and the phenomenon that teeth are damaged due to the overlarge extrusion force between the second bevel gear 31 and the first bevel gear 21 is avoided.
