(10) it is connected with pressure switch (20) by data line (19), pressure transmitter (10) persistently detects to be situated between at valve seat (4) sealing surface
Matter pressure, and give pressure signal transmission to pressure switch (20), pressure, which is carried out, by pressure switch (20) compares in real time, once discovery
Pressure is more than setting value, then determines dielectric leakage, and control cabinet (6) interior green light goes out, red light is bright, issues alarm signal；Pressure simultaneously
Switch (20) sends a signal to control room, dielectric leakage at notice control room valve seat (4).
The beneficial effects of the utility model are: the intelligent gate valve of this patent utility model is persistently examined by pressure transmitter
Pressure medium at sealing surface of seat is surveyed, can find dielectric leakage at valve seat in time, and send a signal to control room, notice control
Dielectric leakage at the valve seat of room, and red alarm is opened, it takes timely measure.Substantially increase the intelligence of valve leak detection.
