Specific embodiment
The embodiments of the present invention is described further with reference to the accompanying drawing.
Fig. 1 is the schematic diagram of the utility model liner molding type electromagnetic flowmeter embodiment, and Fig. 2 is the utility model liner
The side view of molding type electromagnetic flowmeter embodiment, Fig. 3 are that liner is protected in the utility model liner molding type electromagnetic flowmeter
The schematic diagram of embodiment is covered, as shown, a kind of liner molding type electromagnetic flowmeter, including gauge outfit 1 and flowmeter bodies 2, table
First 1 is connect by connection component with flowmeter bodies 2, and connection component includes upper connector 3 and lower connector 4 interconnected,
It is fixed between upper connector 3 and lower connector 4 by flange, upper connector 3 is connect with the signal adapter in gauge outfit 1, lower company
Adapter tube 4 is connect with flowmeter bodies 2.Gauge outfit 1 is added on the magnet exciting coil in flowmeter bodies 2, connects for generating excitation signal
The inductive signal for receiving electrode in simultaneously amplified flow meter ontology 2, then shows related data by display.
Flowmeter bodies 2 are structure as a whole, and strengthen whole intensity.The liner 5 of flowmeter bodies 2 directly with tested Jie
Matter contact, liner 5 are to be molded manufactured electro-insulating rubber pipe.Liner 5 is made of integral die, greatly shortens the life of flowmeter bodies
The period is produced, transport and production cost are reduced.The length of liner 5 is greater than the length of 2 middle tube body of flowmeter bodies, and liner 5 is beyond stream
The tube length of meter ontology 2 adds so that forming interface between the pipeline and flowmeter bodies 2 of 2 left and right sides of flowmeter bodies
Strong flowmeter bodies 2 and seamless the being completely embedded property of pipeline.The electrode 6 through liner 5, electrode 6 are equipped in flowmeter bodies 2
On be connected with threaded rod, the setting of threaded rod is connected firmly to electrode 6 in flowmeter bodies 2.Flowmeter bodies 2 and liner 5
Between be equipped with the magnet exciting coil vertical with electrode 6.
