Bent type power-assisted liquid adding gun head

The utility model discloses a bent type power-assisted liquid adding gun head which comprises a liquid adding gun nozzle assembly which is fixedly connected with a piston on an air cylinder. The liquid adding gun nozzle assembly is connected with the liquid inlet pipe through an arc-shaped bent pipe, and the circle center of the arc-shaped bent pipe is close to the liquid flowing direction side during liquid adding. The liquid adding gun nozzle assembly can be driven to move front and back through front and back movement of a piston on an air cylinder, so that a liquid adding gun nozzle is matched with a liquid adding opening in an LNG vehicle to carry out liquid adding operation, the physical strength of operators is saved, and the liquid adding operation efficiency is improved. The arc-shaped bent pipe is arranged between the liquid adding pipe and the liquid inlet pipe, so that the flowing resistance of liquid in the pipe is reduced, the liquid flows more smoothly, and the liquid inlet speed is higher. 本实用
