Abstract
The utility model belongs to valve preparation technical field, concretely relates to a kind of multi-rotation worm wheel box opening degree indicating mechanism.The opening degree indicating mechanism includes valve opening degree drive shaft, opening degree indicating mechanism component and multi-rotation worm wheel box, opening degree indicating mechanism component includes opening degree indicating mechanism frame and planetary gear mechanism, opening degree indicating mechanism frame is fixedly arranged on multi-rotation worm wheel box, valve opening degree drive shaft is arranged in multi-rotation worm wheel box, and planetary gear mechanism is hinged on valve opening degree drive shaft.Worm wheel box 20 to 50 circle rotation movement can be compressed into the scale disc rotation within 90 degrees, so that valve opening degree is self-evident, and it is convenient to quickly interpret, and planetary gear system uses modularization design, supports quick disassembly and replacement, and it greatly reduces maintenance cost and time.
