Valve position indicator

摘要

A valve position indicator assembly is disclosed herein. The valve position indicator assembly includes a gearing assembly operable to transmit an input rotation to an output rotation. The gearing assembly includes a first gearing member driven to the output rotation by the input rotation. A rate of the output rotation is a fraction of and less than a rate of the input rotation. The valve position indicator assembly includes: a position indicia engaged with the first gearing member such that the indicia and the first gearing member move together; a scale plate including a plurality of graduated indicia defining a scale of rotation movement of the first gearing member; and a mounting bracket comprising a first slot having a length extending between a first end and a second end.

1. A valve position indicator assembly comprising:
a gearing assembly operable to transmit an input rotation to an output rotation, wherein said gearing assembly includes a first gearing member driven to the output rotation by the input rotation, and wherein a rate of the output rotation is a fraction of and less than a rate of the input rotation; a position indicia engaged with said first gearing member such that said indicia and said first gearing member jointly move together; a scale plate including a plurality of graduated indicia defining a scale of rotation movement of said first gearing member, said scale plate disposed proximate to said first gearing member such that said position indicia passes across said scale of said scale plate during the output rotation; and a mounting bracket comprising a first slot having a length extending between a first end and a second end, wherein said gearing assembly and said position indicia and said scale plate are mounted with respect to said first slot for adjustable positioning over at least part of said length.
