Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of pressure pipelines, in particular to a device for accurately measuring steam. Background Art
[0002] In industrial applications, steam is an energy carrier, and accurate measurement of its usage is crucial for energy management and cost control. Traditional steam pipeline systems usually install flow meters directly on installed pipelines to monitor steam usage.
[0003] However, this traditional method faces some obvious defects. If the size of the flow meter exactly matches the diameter of the existing pipeline, these flow meters often cannot provide accurate measurements when steam usage decreases because their measurement range and sensitivity cannot adapt to the lower flow rate, which leads to the inability to effectively control energy consumption and reduce costs. If you consider dismantling the installed steam pipes and reinstalling new pipes and flow meters that conform to the flow changes, this will involve a large amount of engineering, high costs and a long construction period, which is unrealistic in many cases. This reconstruction work not only affects production, but may also cause long-term operational interruptions. Utility Model Content

The flow meter body 1 is mainly responsible for measuring the amount of steam passing through and providing key data for system optimization and energy management. The reducer 2 is used to connect the flow meter body 1 with pipelines of different diameters to achieve smooth transition of the fluid, thereby avoiding flow loss and measurement error. The first flange 3 and the second flange 4 are used to fix and seal the connection between the flow meter body 1 and the reducer 2 to ensure the stability and leakage resistance of the system. The nut 5 and the bolt 6 are used in combination to tighten the flange to ensure the structural strength and sealing effect of the connection.
[0025] Both ends of the first seamless steel pipe 7 are provided with large and small diameter reducing connectors 8, and both ends of the large and small diameter reducing connectors 8 are provided with second seamless steel pipes 9. The length of the first seamless steel pipes 7 at both ends of the flowmeter body 1 is not less than 1 meter, and the nominal diameter is DN100. The first seamless steel pipe 7 and the second seamless steel pipe 9 serve as the main channels for steam transmission, and are combined with the large and small diameter reducing connectors 8 to adjust the pipe diameter to match the working requirements of the flowmeter body 1.

[0027] Working principle: The flow meter body 1 is the core component, which is used to accurately measure the amount of steam passing through. The flow meter body 1 is connected to the pipeline system through the reducers 2 at both ends. The reducers 2 allow the flow meter to match pipelines of different diameters.

The two ends of the first seamless steel pipe 7 are connected to the second seamless steel pipe 9 through large and small reducer connectors 8. This arrangement makes the transition from the flow meter to the main pipeline smoother and avoids flow The large and small reducers 8 play a key role here, which not only changes the diameter of the pipeline to adapt to different parts, but also is fixedly connected to the first seamless steel pipe 7 and the second seamless steel pipe 9 by welding, thereby increasing the structural strength of the overall system.
