The invention discloses an intelligent circumfluence
pressure regulator, which includes a front valve body and a rear valve body. The front valve body is provided with a center axle hole, the center axle hole is provided with a main valve shaft, a diversion end cover, a wear-resisting sealing
valve seat and a diversion valve head, the diversion valve head is fixed to one end of the main valve shaft, the other end of the main valve shaft is connected with a closed-loop
linear actuator, and the wear-resisting sealing
valve seat is matched with the diversion valve head; the rear valve body is provided with an
internal cavity and an
external cavity which are mutually isolated, the closed-loop
linear actuator is installed and fixed into the
internal cavity, and the
external cavity is a gas outflow channel; and the front valve body and the rear valve body are provided with pressure sensors correspondingly, the front valve body is provided with an
inlet pressure sensor, and the rear valve body is provided with a pressure
transmitter and a display shell. The intelligent circumfluence
pressure regulator can easily realize six operation
modes comprising an automatic pressure regulating mode,an automatic
current limiting mode, an automatic low flow mode, a multi-period pressure reservation mode, a multi-period
current limiting reservation mode and a gas total accumulation mode correspondingly, and meanwhile, the functions such as gas metering are achieved.
