Abstract

The invention discloses a turbine box for a butterfly valve driving device. The turbine box comprises a box body, wherein a mounting shaft is rotationally connected to the surface of one side of the box body, a worm gear is rotationally mounted on the surface of one end of the mounting shaft, an adjusting threaded rod is in threaded connection to the surface of the other side of the box body, and a U-shaped frame is rotationally connected to one end of the adjusting threaded rod; the surface of one side of the U-shaped frame is slidably connected to the side surface of the box body, a worm is rotatably mounted on the surface of the other side of the U-shaped frame, the surface of the worm is meshed with the surface of one side of the worm gear, a long-strip-shaped through groove is formed in the side surface of one end of the box body, and an adjusting shaft is connected to one end of the worm; and the surface of one end of the adjusting shaft is slidably connected to the side surface of the long-strip-shaped through groove, an adjusting hand wheel is fixedly connected to the other end of the adjusting shaft, and a protection plate is fixedly connected to the side surface of the other end of the U-shaped frame, so that use convenience and stability can be greatly improved, and safety and high efficiency of driving adjustment are guaranteed.

Description

technical field [0001] The invention relates to the field of butterfly valves, in particular to a turbine box for a butterfly valve driving device. Background technique [0002] In the current industrial production, the use of butterfly valves is very common. In the drive control of butterfly valves, the turbine box is usually connected to the shaft end to control the adjustment, and the internal worm gear is used for transmission and locking. [0003] However, in the existing structure of the drive turbine box, most of the worm gears are simply positioned and installed. This requires accurate alignment installation, which is not conducive to adjusting the installation gap and causes serious wear of the worm gear. When emergency shutdown is needed like this, the worm wheel cannot be separated and driven directly by the backup structure, which has poor adaptability and insufficient safety, and needs to be improved. Contents of the invention [0004] Aiming at the problems ...
