Abstract

The invention relates to a pressure gauge, and solves the problem that a pressure gauge tends to damage when the pressure of a tested medium is too large. The pressure gauge comprises a housing, a shorted inlet and a shorted outlet are respectively formed at the two ends of the housing, the housing is internally provided with a drive rod, a first cavity is formed by the housing and the end, far from the shorted inlet, of the drive rod, a through hole which is communicated with the shorted inlet and the first cavity is formed in the drive rod, a second cavity is formed by the housing and the end, close to the shorted inlet, of the drive rod, the drive rod in the first and second cavities is in sliding connection with the housing, the second cavity is communicated with the shorted outlet, and the second cavity and the shorted outlet are filled with anti-freeze hydraulic oil. The simple pressure gauge provided by the invention is not damaged when the pressure is too large.

Description

technical field [0001] The invention relates to parts of a pressure gauge, in particular to a simple pressure gauge. Background technique [0002] A pressure gauge is an instrument that uses elastic elements as sensitive elements to measure and indicate pressure higher than the environment. It is widely used, and it pervades almost all industrial processes and scientific research fields. It can be seen everywhere in the fields of heat pipe network, oil and gas transmission, water supply and gas supply system, vehicle maintenance shop, etc., especially in the process of industrial process control and technical measurement, because the elastic sensitive element of the mechanical pressure gauge has high mechanical strength and The characteristics of convenient production make mechanical pressure gauges more and more widely used. [0003] As we all know, pressure gauges can be used to measure the pressure of fluids such as gas or liquid, and are widely used in industry. The pr...
