Electromagnetic metering ball valve

Abstract

The invention discloses an electromagnetic metering ball valve which comprises a valve body, a ball core, a valve rod and an electronic control box, wherein fluid through holes are formed in the ball core; paired electrodes are arranged in the fluid through holes, are provided with electro-magnetic induction coils in a relative manner, and are arranged in the magnetic field range of the electro-magnetic induction coils; fluid flows through the electro-magnetic induction coils and the electrodes and generates induced current in the electrodes; a circuit board is arranged in the electronic control box; a processing module capable of processing the induced current of the electrodes to obtain the real-time flow information of fluid is arranged on the circuit board. The electromagnetic metering ball valve has the following benefits: the electromagnetic metering manner is adopted to measure fluid flow, so that the measuring accuracy is high, the problem that a valve and a flowmeter are mounted separately in a pipeline is solved, and the cost is reduced; opening and closing of a butterfly bamper can be realized in a remote wireless control manner according to real-time flow, and the remote wireless control manner according to real-time flow is suitable for unified automated management, and remote control and maintenance of the pipeline.

Description

technical field [0001] The invention relates to the technical field of valves and fluid metering, in particular to an electromagnetic metering ball valve. Background technique [0002] The ball valve is not only simple in structure and good in sealing performance, but also has the advantages of small size, light weight, less material consumption, small installation size, small driving torque, easy operation, and easy quick opening and closing within a certain nominal size range. One of the fastest growing valve varieties in the past ten years. [0003] The use of ball valves is very extensive, and the variety and quantity of use are still expanding, and they are developing in the direction of high temperature, high pressure, large diameter, high sealing, long life, excellent adjustment performance, and one valve with multiple functions. Its functional diversity has become an important indicator to show the technical level of the national valve industry, and it is also an im...

Problems solved by technology

[0005] The purpose of the present invention is to overcome the problem that most of the existing ball valves are only used to cut off, cut off and change the flow direction of the fluid in the fluid pipeline, and most of the valves and flow meters in the pipeline are installed separately. Electromagnetic metering ball valve, which has the characteristics of not only controlling fluid on-off, but also measuring fluid flow, high measurement accuracy, long service life, convenient installation and maintenance, and remote wireless control of opening and closing valves.
