The utility model discloses the working process:

The utility model relates to an online monitoring air valve, install the air valve in reasonable positions such as pipeline high point, turning, when the pipe network stops the medium outflow such as using, in time make up air and prevent the negative pressure from appearing, namely when the pressure that the air valve position is in is less than the outside atmospheric pressure of this place, the floater whereabouts in the valve lets the outside air enter the pipe network through the air valve, in order to reduce the negative pressure; on the other hand, when the pressure at the position where the air valve is installed is higher than the external atmospheric pressure, the air in the pipeline is discharged through the valve, the liquid in the pipeline network cannot be discharged together with the air, and after the gas is discharged, the floating ball in the air valve rises to block the flow passage opening so as to close the air valve. From this, the air valve can reduce the negative pressure through the mode of admitting air on the one hand, avoids the emergence of "water column separation" phenomenon, and then prevents to produce in the pipeline and close the water hammer to avoid the water hammer accident, on the other hand trace exhaust function can discharge the normal operation aquatic effusion trace air, avoids the effusion gas to form the hindrance to water delivery. By mounting the sensing element on a conventional air valve, the problem of unreliable or after-failure agnostic valves due to operational, quality and media conditions, etc. is avoided.

The above-mentioned embodiment is right the utility model discloses an explanation, it is not right the utility model discloses a limited, any right the scheme after the simple transform of the utility model all belongs to the protection scope of the utility model.
