Description

Technical Field

[0001] The utility model relates to the technical field of flow meters, in particular to a flow meter with heat insulation effect. Background Art

[0002] A flow meter is an instrument used to measure the volume or mass of a fluid (such as liquid or gas) passing through a certain cross-section per unit time. With the continuous development of the industrial field, flow meters are increasingly used in various fields such as chemical industry, electric power, water treatment, and medicine. Especially in the measurement of high-temperature fluids, the accuracy and stability of flow meters have become key factors affecting industrial production.

[0003] In order to meet the measurement needs in high-temperature environments, some traditional flow meters improve their heat resistance by improving materials and structural designs. For example, high-temperature alloys or ceramic materials are used to make sensors and meter bodies to reduce the impact of high temperature on material properties, thereby ensuring the normal operation of the flow meter in high-temperature environments.

[0004] However, although these improvement measures have improved the heat resistance of the flow meter to a certain extent, there are still some problems. Especially in long-term high-temperature operations, due to the continuous accumulation and transfer of heat, the performance of the flow meter body will still be affected, shortening the service life of the flow meter. The heat insulation effect is not ideal, and heat can still be transferred through the meter body to the flow meter body, resulting in safety hazards. In view of this, we propose a flow meter with heat insulation effect. Utility Model Content

When the flow meter body 8 is installed into the vertical pipe 4 through the annular plate 137, the short column 138 and the roller 1310 are cooperated to make the spring plate 139 swing and shift, so that the elastic potential energy of the spring plate 139 makes the sealing airbag 1311 fit tightly against the outer wall of the flow meter body 8, and at the same time, the compression deformation of the reset spring 1312 makes the sealing airbag 1311 and the flow meter body 8 fit more closely, so that the sealing of the equipment body is better, and then better heat insulation and sealing can be ensured. Furthermore, when the center shaft 11 rotates, the circular sleeve 141 is driven to rotate synchronously, thereby driving the connecting rod 142 to rotate synchronously, thereby driving the circular rod 143 to rotate synchronously, thereby driving the scraper 144 to rotate synchronously, so that the scraper 144 can scrape the inner wall of the main pipe 1, thereby avoiding impurities adhering to the outside of the sensing probe 9 to affect the measurement accuracy, and then making the measurement effect better.
