Pressure abnormity and interval display structure of pressure gauge

Abstract

The invention provides a pressure abnormity and interval display structure of a pressure gauge. A first index unit, a second index unit and a third index unit are arranged on a transparent panel of the pressure gauge, and the index units are used for adjusting positions; two of the index units are used for setting the positions of a low pressure scale and a high pressure scale respectively, and the other index unit is driven by the pressure pointer to change the position if an overpressure condition exists after setting, so that field staff can know the overpressure condition conveniently. Practical pressure abnormity and interval display is provided, and actual requirements are met.

Description

technical field [0001] The invention relates to a pressure abnormality and interval display structure of a pressure gauge, which relates to a numerical interval warning structure of a pointer pressure gauge, and especially refers to a technical field in which a pressure gauge can display its overpressure value after overpressure. Background technique [0002] There is fluid pressure inside many fluid pipelines, equipment or machines. In order to ensure their normal operation and normal pressure monitoring, these fluid pipelines, equipment or machines will be equipped with pressure gauges. A pressure pointer is installed in the traditional pointer pressure gauge, and the pressure pointer can display the pressure value in real time. With the panel below the pressure pointer and the scale on the panel, the staff can know the current pressure value. However, the pressure values ​​of pressure gauges at different locations are mostly different. It is very necessary to let the staf...

AI Technical Summary

Problems solved by technology

[0004] In order to improve the defect that personnel cannot know the abnormality and value after the instantaneous overpressure of the aforementioned pointer pressure gauge, the main purpose of the present invention is to provide a pressure gauge with a display structure for abnormal pressure and intervals, which can not only set the low standard critical value of the pressure In addition to visually confirming whether the pressure is normal, a pointer for abnormal overpressure display can be linked by the pressure pointer to change its position when abnormal overpressure occurs, and then stay at the overpressure position. The pressure value; in this way, the staff can visually know whether there is an abnormal overpressure situation, and know the pressure value of the overpressure; thereby, it is possible to perform troubleshooting and abnormal processing in real time to ensure on-site safety
