Abstract
The invention discloses an electromagnetic flow meter. The electromagnetic flow meter comprises a junction box, a ball valve, an inserting rod and a detection head, wherein a handle is arranged below the junction box; a locking nut is arranged below the handle; the ball valve is arranged below the locking nut; a fastening bolt is arranged below the ball valve; the fastening bolt is connected with a flange short tube; the flange short tube is hermetically connected to an industrial pipeline; the inserting rod is arranged in the flange short tube; the detection head is arranged at the bottom end of the inserting rod. The electromagnetic flow meter is simple in structure, and is convenient to use; meanwhile, the ball valve is arranged, so that convenience is brought to disassembly, assembly and maintenance, the maintenance cost is lowered, the service life is prolonged, and high measuring accuracy is achieved.
Description
Technical field
The present invention relates to the technical field of flowmeter, be specially a kind of electromagnetic flowmeter.
Background technology
Electromagnetic flowmeter is the new type of flowmeter developed rapidly along with the development of electronic technology 50 ~ sixties of 20th century.Electromagnetic flowmeter is the Ferraris instrument being used for conducting medium volumetric flow rate in measuring tube according to Faraday's electromagnetic induction law manufacture.Electromagnetic flowmeter is divided into regard to display mode: separation type electromagnetic flowmeter, one-piece type electromagnetic flowmeter.Separation type electromagnetic flowmeter is a kind of Ferraris instrument carrying out conducting medium volumetric flow rate in measuring tube according to Faraday's electromagnetic induction law, adopt microcontroller embedded technology, realize digital excitation, on electromagnetic flowmeter, adopt CAN fieldbus simultaneously, belong to domestic initiation, technology reaches domestically leading level.One-piece type electromagnetic flowmeter formulates according to Faraday's electromagnetic induction law, is used for measuring the volumetric flow rate of conductive fluid.Feature due to uniqueness has been widely used in the measurement of industrial various conducting liquid.Be mainly used in the industries such as chemical industry, papermaking, food, weaving, metallurgy, environmental protection, plumbing, control with the supporting feasible system of computing machine.
Traditional electromagnetic flowmeter adopts average discharge bayonet point, and in measurement out of true, and traditional detection head volume is large, easily causes choked flow, and electromagnetic flowmeter is not easy to realize dismounting simultaneously, and installation and maintenance are very inconvenient.
Summary of the invention
The object of this invention is to provide a kind of structure simple, easy to operate, the electromagnetic flowmeter that can accurately measure.
The present invention is achieved through the following technical solutions:
A kind of electromagnetic flowmeter, comprise terminal box, ball valve, insertion rod and detection head, handle is provided with below described terminal box, under described handle, set nut is installed, below described set nut, is provided with ball valve, below described ball valve, be provided with fastening bolt, described fastening bolt connects a flange short tube, described flange short tube is tightly connected on industrial pipeline, is provided with insertion rod in described flange short tube, and described insertion rod bottom is provided with detection head.
Further, sealing packed layer is provided with between described set nut and ball valve.
Further, described detection head bottom is provided with electrode.
The invention has the beneficial effects as follows: structure is simple, easy to use, the setting of ball valve simultaneously makes dismounting, convenient for installation and maintenance, reduce maintenance cost, improve serviceable life, and measuring accuracy is high.
