The invention relates to a digitized intelligent long-distance remote-control water injection valve. The water injection valve comprise a control valve and a flowmeter which are connected in series with a
water pipe, wherein the control valve is an electric flow regulating valve, the flowmeter is an electromagnetic type flowmeter, and the water injection valve also comprises a PID (
piping and instruments diagram) controller and a telecommunication
system; a data output end of the electromagnetic type flowmeter is connected with an input end of the
PID controller, a control output end of the
PID controller is connected with the electric flow regulating valve, and a
wireless remote connection is established between the other interface of the
PID controller and a control management centre through the telecommunication
system; and the PID controller is connected with a display and an operating key. The water injection valve provided by the invention integrates the electric flow regulating valve, the electromagnetic type flow meter, the PID controller and the telecommunication
system into a whole, can carry out
remote data transmission and networked combination control, non-manpower
automatic control water and report
data entry are realized, the operating efficiency is improved, and errors caused by manual operation are avoided; and the water injection valve can be directly changed and handled on an original pipeline design and is convenient and rapid to install.
