Dynamic pressure sensing mechanism with pressure-bearing bracket

Abstract

The invention relates to the technical field of sensors, and discloses a dynamic pressure sensing mechanism with a pressure-bearing support, and the mechanism comprises a housing, a bottom plate is disposed at the bottom in the housing, an anti-impact box is disposed above the bottom plate, a plurality of bent pipes are disposed in the anti-impact box, reset rods are disposed in the bent pipes, and permanent magnets are movably connected to the upper ends of the reset rods. The upper end of the air bag is movably connected with a pressure bearing column, a positioning ring is arranged on the outer side of the upper portion of the pressure bearing column, a constant-pressure pipe is arranged on the outer side of the positioning ring, a ruler is arranged outside the constant-pressure pipe, and an adjusting block is arranged in the constant-pressure pipe. According to the dynamic pressure sensing mechanism with the pressure-bearing support, air in the air bag is compressed for primary buffering, air pressure is transmitted to the bent pipe to drive the permanent magnet block to ascend, and the permanent magnet block fully unloads force under the action of tension of the reset rod and a damping magnetic field generated by the damping coil, thereby resisting the impact load and preventing overload damage of a sensing device.

Description

technical field [0001] The invention relates to the technical field of sensors, in particular to a dynamic pressure sensing mechanism with a pressure bearing bracket. Background technique [0002] The dynamic pressure sensor is a sensor used in some large pressure equipment such as boilers. Because the range and sensitivity of the detection value are larger than ordinary sensors, the requirements are higher, and it is difficult to replace, and the design life is generally very long. However, due to its specific working environment, it often encounters a large impact load, which reduces the sensitivity of the sensitive element, and its service life is far less than the design life. Contents of the invention [0003] (1) Solved technical problems [0004] Aiming at the deficiencies of the prior art, the present invention provides a dynamic pressure sensing mechanism with a pressure-bearing bracket, which has the advantages of supporting and buffering functions, prolonging t...
