The invention discloses a bottle valve assembly with pressure monitoring. The bottle valve assembly with pressure monitoring comprises a valve body, an air inlet channel is connected to the lower endof the valve body, an air outlet channel is connected to the left end of the valve body, and a bottle-opening guiding subassembly is connected to the right end of the valve body; the air inlet channelis used for being connected with an air bottle, the air outlet channel is used for being connected with an air sac, and a piston rod is arranged in an inner cavity of the valve body and sleeved withtwo pistons; when a releasing valve assembly is in the closed state, the two pistons are distributed on the two sides of the air inlet channel, the inner cavity of the valve body is divided into threecavity bodies of the left cavity body, the middle cavity body and the right cavity body, the left cavity body is communicated with the air outlet channel, the middle cavity body is communicated withthe air inlet channel, an air discharging opening is connected to the right cavity body and communicated with atmosphere, and an air outlet nozzle is arranged in an air releasing channel; a pressure sensor is also arranged on the valve body and arranged on the air inlet channel; the bottle-opening guiding subassembly comprises an electric initiator. Online real-time monitoring of air bottle pressure is achieved, the performance is stable and reliable, and high-pressure gas is rapidly started accordingly.
