Monitoring device for boiler pressure vessel and using method thereof

Abstract

The invention relates to the technical field of pressure vessel monitoring, in particular to a monitoring device for a boiler pressure vessel and a using method thereof. The monitoring device comprises an outer barrel and a sealing block, the sealing block is slidably connected into the outer barrel, a lower mounting plate is fixedly connected to the middle of the lower end of the sealing block, a guide rod is fixedly connected to the middle of the lower end of the lower mounting plate, a connecting flange plate is slidably connected to the outer side of the guide rod, a sealing ring is arranged on the upper side of the connecting flange plate, the upper portion of the outer side of the connecting flange plate is fixedly connected with the outer cylinder through threads, and a fixing bolt is arranged in the connecting flange plate. Through arrangement of the connecting flange plate, the sealing ring, a pressure sensor, a temperature sensor, the sealing block, the guide rod, a threaded rod, a rotating ring, a lower buffer spring, a lower buffer pad, an upper buffer spring and an upper buffer pad, the device is convenient to mount and fix, temperature and pressure information in a pressure container can be obtained in time, and physical parameter values in the pressure container can be detected in multiple directions.

Description

technical field [0001] The invention relates to the technical field of pressure vessel monitoring, in particular to a monitoring device for a boiler pressure vessel and an application method thereof. Background technique [0002] A pressure vessel refers to a closed device that holds gas or liquid and carries a certain pressure. In order to implement scientific management and safety supervision and inspection more effectively, my country's The function divides the pressure vessel into three categories. The pressure vessel is a closed vessel that can withstand pressure. The pressure vessel has a wide range of uses. It plays an important role in many sectors such as industry, civil, military and scientific research. Among them, the most used in the chemical industry and the petrochemical industry, the pressure vessels used in the petrochemical industry alone account for about 50% of the total number of pressure vessels, and the pressure vessels in the chemical and petrochemical ...

Problems solved by technology

[0003]Pressure vessels play an important role in the boiler system. During the operation of the boiler system, it is necessary to detect the physical parameter values ​​of each pressure vessel at all times, such as temperature information and pressure information, etc. , in order to ensure the safety of the boiler system operation, most of the ordinary detection devices are fixed on the surface of the container, and its sealing performance is poor, which may easily lead to pressure leakage of the container, and can only detect the temperature and pressure information on the outer surface of the container, and it is difficult to obtain the inside of the container The temperature and pressure values ​​in the depths lead to deviations in the detection results. Therefore, in view of the above problems, a monitoring device for boiler pressure vessels and its application method are proposed
