Overpressure-resisting pressure instrument

Abstract

The invention provides an overpressure-resisting pressure instrument which comprises an instrument main body, wherein a protecting shell made from stainless steel is detachably connected on the outer side of the instrument main body; the instrument main body comprises an instrument plate, an inner shell and a base in turn from top to bottom; a moveable pressure-resisting net is arranged at the upper end of the base; a sensor is arranged above the pressure-resisting net; the powder metallurgy is arranged above the sensor; the powder metallurgy is fixedly mounted on a powder metallurgy mounting body; the upper end of the powder metallurgy is fixedly connected with a copper tube through a damp bolt; a connecting loop sleeves the outer side of the copper tube; a terminal is arranged at the upper end of the connecting loop; under the shaking of the copper tube, the connecting loop is in contact with the terminal; the terminal also is connected with an intelligent meter for showing a measuring result. The overpressure-resisting pressure instrument has the beneficial effects that the instrument main body has two protecting wires in an overpressure measuring process due to the design of the protecting shell and the pressure-resisting net, so that the overpressure resistance of the instrument main body is promoted and the service life of the instrument main body is prolonged.

Description

technical field [0001] The invention relates to the technical field of sensors and measuring instruments, in particular to an anti-overpressure pressure instrument. Background technique [0002] In the process of pressure measurement, because the pressure to be measured is in an unknown state, the pressure instrument may be subjected to high overload pressure. When the pressure gauge does not take any anti-overpressure countermeasures, the overload pressure will cause the pressure gauge to be seriously damaged. However, traditional pressure instruments do not have the ability to resist overpressure, so the traditional pressure instruments are damaged due to the pressure exceeding the measurement range during pressure measurement, and cannot continue to be used. It can be seen that how to develop an anti-overpressure pressure instrument with good anti-pressure ability to improve the service life of the pressure measurement instrument is an urgent problem to be solved by thos...
