Industrial boilers, which are commonly known as circulating fluidized bed boilers, industrial boilers are important thermal power equipment, because the boilers are closed containers, when the pressure in the boiler rises and exceeds the allowable working pressure, and safety accessories fail to alarm in time and exhaust steam and reduce pressure, so that the pressure in the boiler continuously rises and exceeds the limit pressure which can be borne by a certain pressure element, explosion is easy to occur, in order to ensure the safety of the boiler, the boiler needs to operate under the safety pressure, and in addition, the pressure in the boiler also needs to be known at all times due to the knowledge of the operating state of the boiler and the requirements of users. The measurement of the pressure in the boiler is currently performed by direct reading with a pressure gauge connected to the boiler.

The existing pressure gauge is simple in structure, poor in protection performance, weak in sealing effect, weak in stability, unstable in structure, troublesome in installation and storage, inconvenient to fix, incapable of shaking after installation, poor in limiting effect, and not easy to replace after the pressure gauge body is damaged.
