Description

Pressure detection device Technical Field The utility model relates to the technical field of pressure detection, in particular to a pressure detection device. Background In petrochemical industry, energy and other industries, pressure monitoring of pipelines and pressure vessels is relevant to production safety and personnel life health. In the petroleum pipeline transportation process, serious accidents such as leakage, explosion and the like can be caused by abnormal pressure. In the past, the manual inspection and the simple instrument monitoring are relied on, so that the efficiency is low, the pressure change cannot be captured in real time, and potential safety hazards are difficult to discover in time. In the prior art, when the sucker rod touches an obstacle or presses an object to be sucked, a reaction force is generated to push the piston of the cylinder to move, the gas in the cylinder is compressed due to the movement of the piston, the pressure in the cylinder is increased due to the reduction of the volume of the gas, at the moment, the pressure sensor connected with the cylinder can detect the change of the pressure, and the piston is inevitably subjected to the action of friction force when moving in the cylinder.
