It fills safety relief valve (9), when leaking medium pressure is more than the operating pressure of pressure transmitter (10), safety relief valve (9) is opened
It releases medium, guarantees pressure transmitter (10) trouble free service.
When the intelligent gate valve is closed, valve rod (7) drives flap (3) downlink, and flap (3) and valve seat (4) sealing surface are tight
Closely connected conjunction, valve close sealing.Valve seat (4) is provided with annular groove (11) on outer diameter circumferencial direction, and annular groove (11) is logical with valve body (8)
Hole (15) connection；Annular groove (14) are machined at valve seat (4) sealing surface, it is uniformly distributed multiple along centerline direction in groove (14)
Blind hole (12), and aperture (13) are arranged in same throwing face, it is connected to groove (14) with annular groove (11), and then valve seat (4) seals
The groove (14) in face is connected to the through-hole (15) of valve body (8).When valve leak, leaking medium can pass through groove (14), blind hole
(12), aperture (13) converges rapidly in annular groove (11).Pressure transmitter (10) passes through threeway (1), pipe fitting (2), valve body (8)
Through-hole (15) be connected to the annular groove (11) of valve seat, groove (14) interior pressure medium of real-time detection valve seat (4) sealing surface, and will
Pressure medium passes to rapidly the pressure switch (20) on valve deck (5) in control cabinet (6).
Setting pressure switch (20) and signal lamp (21) (including red light and green light), pressure transmitter in control cabinet (6)
(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 present invention are: the intelligent gate valve of invention is by pressure transmitter, persistently to detect valve seat close
Pressure medium at cover can find dielectric leakage at valve seat in time, and send a signal to control room, notify at control room valve seat
Dielectric leakage, and red alarm is opened, it takes timely measure.Substantially increase the intelligence of valve leak detection.
