Abstract

The present invention provides a clock type display for a pipeline ball passing indicator. A mechanical clock core, an electromagnetic switch, a tappet flip-flop mechanism and a clamp limiting mechanism are arranged in the clock type display. The functions of timing, warning and the remote transmission of ball passing signals are completed by being matched with a ball passing indicator. When a ball arrives at an installation point of the indicator, the ball shocks a trigger, and a tappet is raised by a transfer mechanism. A spring piece leans on a balance wheel of the mechanical clock core to stop a clock, and a bell rings. The time of the ball passing through the installation point is displayed on site, and the signal is transmitted to a duty room through a cable for the convenience of analyzing the operating state of the ball in a pipeline. The present invention is suitable for being used on oil (gas) pipelines.

Description

Clock-type display for pipeline through ball indicator

The invention belongs to a kind of oil transportation (gas) pipeline with leading to ball indicator, it finishes the function that logical ball shows under the cooperation of logical ball indicator.
