Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of electromagnetic flowmeters, and in particular relates to a quick-install electromagnetic flowmeter. Background Art
[0002] Electromagnetic flowmeter is an instrument that measures the flow rate of conductive fluid based on the electromotive force generated when the conductive fluid passes through an external magnetic field. It is mainly composed of a magnetic circuit system, a measuring conduit, an electrode, a housing, a lining and a converter. Electromagnetic flowmeters are suitable for measuring the volume of conductive liquids and slurries in closed pipe flows, such as clean water, sewage, various acid, alkali and salt solutions, slurries, pulp, syrups and edible liquids. At present, the installation methods of electromagnetic flowmeters mainly cover two categories: flange connection and direct plug-in connection. The former involves flange welding at the cut end of the pipeline. This process is not only time-consuming, but also has extremely low tolerance for cutting errors, which significantly increases the complexity of installation. The latter is to directly insert the end of the fluid pipeline to be measured into the port of the flowmeter, and use the corresponding locking mechanism to firmly connect to prevent the pipeline port from falling off. However, direct plug-in connection is usually more suitable for the initial stage of pipeline installation. Although it is convenient for direct insertion of the pipeline, its versatility is relatively limited. In view of this, the utility model proposes a quick-install electromagnetic flowmeter, which aims to shorten the installation period, simplify the installation process, and ensure convenient installation operations both in the early and late stages of pipeline installation, thereby significantly improving its versatility.
[0003] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content
[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a quick-install electromagnetic flowmeter, comprising a flowmeter body, wherein both ends of the measuring tube of the flowmeter body are provided with connection structures, wherein the connection structures include an upper port tube sheet and a lower port tube sheet, wherein one end of the upper port tube sheet is connected to the port of the measuring tube of the flowmeter body, and connectors are welded at one side edge of the upper port tube sheet and the lower port tube sheet, wherein the connector of the upper port tube sheet and the connector of the lower port tube sheet are fastened and connected by bolts, and sealing gaskets are installed between the inner walls of the lower port tube sheet and the upper port tube sheet and the joints of the two connectors.
[0005] As a preferred technical solution of the utility model, the port upper tube plate and the port lower tube plate are spliced up and down to form a circular tube structure, and the connectors are respectively arranged at the circular tube splicing positions of the port upper tube plate and the port lower tube plate.
[0006] As a preferred technical solution of the utility model, the port upper tube plate and the measuring tube inner tube of the flowmeter body are an integrally formed structure.
[0007] As a preferred technical solution of the utility model, an adjusting strip hole is opened inside the connector, and the connector of the port upper tube sheet and the connector of the port lower tube sheet are fastened and connected by bolts passing through the adjusting strip hole.
[0008] As a preferred technical solution of the utility model, the number of bolts fastened between the connector of the port upper tube sheet and the connector of the port lower tube sheet is greater than or equal to.
[0009] As a preferred technical solution of the present utility model, the sealing gasket is made of rubber.
[0010] Compared with the prior art, the beneficial effects of the utility model are:
[0011] The utility model realizes connection by pressing the ends of the pipe up and down. Compared with the traditional flange structure, this design does not require flange welding at the cut end of the pipe, which significantly shortens the installation period and provides a greater tolerance for cutting errors, thereby greatly reducing the complexity of installation. At the same time, compared with the plug-in connection structure, the utility model can be easily installed before and after the installation of the pipe, demonstrating its high versatility. Specifically, the structure presses the pipe port through the upper and lower tube sheets with bolts, and installs a sealing gasket on the pressing surface. This design not only utilizes the clamping force, but also uses the friction between the pipe wall and the sealing gasket, effectively avoiding the safety hazards that may be caused by the pipe port falling off and liquid leakage, and ensuring the safety and reliability of the connection.
