Flow-adjustable single-channel storage type plug water-distributing pressure gauge

The invention relates to a flow-adjustable single-channel storage type plug water-distributing pressure gauge. The pressure gauge comprises a fishing head, the outer wall of the fishing head is sequentially sleeved with a pressing cap and a limiting spring, the lower end of the pressing cap is connected with an upper shell, a locking cam is fixed in the middle of the upper shell, a lower adjusting rod is arranged in the cavity at the lower part of the upper shell, the lower adjusting rod is radially provided with a pressure conduction hole, the upper shell is connected with a middle shell through a connector, the upper part of the connector is provided with a water outlet, the water outlet is communicated with the pressure conduction hole, a fixed water nozzle and a movable water nozzle are parallelly and transversely arranged in the cavity of the connector below the lower adjusting rod, a lower compressed spring is arranged in the cavity at the lower part of the connector, the lower part of the connector is provided with a water inlet, the lower end of the middle shell is connected with a lower shell, and a pressure gauge, a circuit board carrier and a battery tank are arranged in the cavities of the middle shell and the lower shell. The pressure gauge disclosed by the invention can achieve an effect of testing and recording formation pressure or the pressure behind nozzles in the process of water injection, and also can achieve an effect of carrying out water distribution on a target layer, and in the process of water distribution, the water quantity of the target layer can be changed directly.
