Abstract

The invention discloses an industrial boiler pressure gauge structure, and belongs to the technical field of instruments. The peripheral side of the pressure gauge body is fixedly connected with a fixing cylinder, first tempered glass is fixedly connected to the front end of the interior of the fixing cylinder, a cavity is formed between the first tempered glass and the pressure gauge body, a rearcover is fixedly connected to the rear end of the interior of the fixing cylinder, the pressure gauge body is fixed in the fixing cylinder and protected by the rear cover and the first tempered glass, then the fixing cylinder is placed in a groove of the shell, double protection is carried out on the pressure gauge body by matching a sealing mechanism with a pipe hoop, and when the pressure gaugebody needs to be replaced or maintained, the shell and the sealing mechanism can be separated through the pipe hoop, so that the pressure gauge body is replaced or maintained. Boilers of different types can be subjected to pressure measurement through a communicating mechanism, then the device is installed on the boiler through an installing mechanism, and the stability is guaranteed.

Description

technical field [0001] The invention relates to the technical field of instruments, and more specifically relates to a structure of an industrial boiler pressure gauge. Background technique [0002] There are two types of industrial boiler products. One is steam, which is used for power generation or gas supply. For example, chemical fertilizer plants can be vaporized with steam, and coal is used as raw material to synthesize chemical fertilizers. This is a typical industrial boiler. Industrial boilers are still dominated by coal. Most, gas-fired waste heat boilers are generally used to recover waste heat. Commonly used in industrial boilers are circulating fluidized bed boilers. Industrial boilers are important thermal power equipment. Since the boiler is a closed container, when the pressure in the boiler rises and exceeds the allowable working pressure, and the safety accessories fail, the alarm and alarm cannot be timely Exhaust steam to lower the pressure, causing the ...
