Description

Technical Field

[0001] The utility model relates to the technical field of pipeline devices, and specifically discloses a pipeline protection device which is convenient for detection by an externally attached flow meter probe. Background Art

[0002] The external ultrasonic flowmeter is a commonly used device in modern industry, mainly used to detect the flow rate of liquid in the pipeline. It consists of two main parts: the transmitter and the sensor. The transmitter is independent, while the sensor needs to be close to the outer wall of the pipeline. The principle of time difference measurement is used to calculate the flow rate of liquid in the pipeline. Pipelines used to transport oil usually have a layer of insulation skin wrapped around the outside of the pipeline, and insulation materials are filled in the gap to protect the pipeline. The insulation skin usually wraps the probe of the ultrasonic flowmeter together. The probe can only be seen after removing part of the insulation skin, which makes it difficult to inspect and maintain the ultrasonic flowmeter.

[0003] At present, if you want to inspect and maintain the ultrasonic flow meter probe, you must first remove the external insulation skin, and then restore the insulation skin after the work is completed, which is time-consuming and laborious. In addition, when installing the insulation skin, multiple metal insulation skins are spirally wound, and each section covers each other. The size of each insulation skin and the number of windings are different. Due to the effect of pressure, the insulation skin will deform to adapt to the current position, so when disassembling, you must remember the position of each section of the insulation skin, otherwise it will not be sealed tightly after installation, and the protection of the pipeline and equipment will be lost.

[0004] Therefore, it is necessary to develop a pipeline protection device for an external flow meter probe to overcome the above problems and facilitate maintenance. Utility Model Content

[0005] The problem to be solved by the present invention is to provide a pipeline protection device that is convenient for external flow meter probe detection, which not only eliminates the need for disassembly and assembly of the insulation skin, but also facilitates the inspection and maintenance of the equipment, and is connected with other parts of the insulation skin to ensure the protection effect on the pipeline and equipment.

[0006] The technical solution adopted by the utility model is as follows:
