Problems solved by technology

For this kind of pressure gauge, if the pressure of the measured medium continues to increase, the piston will go up all the time, and the antifreeze hydraulic oil will exert pressure on the inside of the pressure gauge, and make the pointer continuously move towards the maximum range until the pointer moves to the maximum range. When the pressure is too high, the pointer exceeds the maximum range or breaks, which eventually leads to damage to the pressure gauge

Abstract

The invention relates to a part of a compression gauge, and discloses a compression gauge cut-off type short circuit. The compression gauge cut-off type short circuit comprises a short circuit body which is internally provided with a main chamber; one end of the main chamber is provided with a short circuit inlet, and the other end of the main chamber is provided with a short circuit outlet; the short circuit body is provided with a bypass chamber which is communicated with the main chamber; a sliding rod with a groove is slidably connected to the wall of the short circuit body of the bypass chamber; a first spring is connected between the sliding rod and the short circuit body wall of the bypass chamber; a cutting rod is arranged on the upper part of the sliding rod and is passed by the sliding rod; the cutting rod passes through the short circuit body of the main chamber and is in sliding connection with the wall of the short circuit body of the main chamber; and a second spring is positioned between one side of the cutting rod which is far away from the short circuit body of the main chamber and the wall of the short circuit body of the bypass chamber. The compression gauge cut-off circuit solves the problem that the compression gauge is damaged when the detected medium is under big pressure, and provides a short circuit preventing the compression gauge from being damaged when the pressure is too much.

Description

technical field [0001] The invention relates to a component of a pressure gauge, in particular to a pressure gauge cut-off short circuit. Background technique [0002] The short connection of the pressure gauge refers to the connection compensation between the pressure gauge and the measured medium pipeline, which is used to connect the connection between the inside of the pressure gauge and the inside of the pipeline. [0003] The Chinese patent number is CN201420698953.5, which discloses a pressure gauge cut-off short circuit. The upper end of the pressure gauge cut-off short circuit housing is provided with an internal thread connected to the pressure gauge head, and the lower end of the housing is provided with a The external thread connected with the pipeline valve; the cavity of the housing has a piston built in, and two parallel annular grooves are opened on the side wall of the piston, and sealing rubber rings are fixed in the two annular grooves; the upper end of th...
