Referring to fig. 1 and 2, the electric valve comprises an electric valve body 1, and the electric valve body 1 is composed of a water inlet pipe 11, a valve, an electric actuator and a water outlet pipe 12. The water outlet pipe 12 is provided with a rectifying device 2 and a flowmeter 3 in sequence along the flowing direction of the medium in the electric valve body 1. When the valve of the electric valve body 1 is opened, the medium in the electric valve body 1 flows into the water outlet pipe 12, and flows through the rectifying device 2 and the flowmeter 3 in the water outlet pipe 12 in sequence, and after the rectifying device 2 consumes the impact force of the medium in the water outlet pipe 12 to a certain extent, the medium smoothly flows through the flowmeter 3.

The staff judges whether pipe explosion and water leakage occur in the production system by checking whether the flow value detected by the flowmeter 3 is larger than the maximum flow value or not generating the flow value in the detection time period. Meanwhile, a worker can use the flowmeter 3 to count the medium passing through the pipeline, and the electric actuating mechanism of the electric valve body 1 is connected by means of a control processing system such as a computer and a PLC central control machine, so that data feedback and opening and closing of the electric valve body 1 are timely carried out, and the medium flowing through the electric valve is accurately quantified.
