Description

[0002] In the modern industrial field, whether it is petrochemical, energy production, machinery manufacturing or aerospace, accurate measurement and control of pressure is a vital link, and the pressure gauge, as an indispensable instrument in this process, has become a key tool for industrial monitoring and safety assurance with its intuitive and accurate characteristics; the working principle of the pressure gauge is based on the deformation of elastic elements (such as spring tubes, diaphragm boxes, bellows, etc.) under pressure. When the pressure of the measured medium (such as gas, liquid) acts on the elastic element, the element will produce corresponding elastic deformation, which is converted into the rotation or linear displacement of the pointer through the mechanical transmission mechanism, thereby indicating the corresponding pressure value on the dial. Different types of pressure gauges may use different elastic elements and transmission mechanisms to meet the measurement requirements under different working conditions; the connecting pipes of the existing pressure measurement and calibration devices are all welded or fixedly connected, but after long-term use, some connecting elements need to be replaced, and the connecting pipes cannot be quickly disassembled, affecting the processing efficiency. When measuring, the existing pressure measurement and calibration device places two raw material barrels next to it to detect the raw materials, but the two large raw material barrels cannot classify and detect more raw materials.
