The utility model discloses a meteorological automatic inflation fine device of sounding, including hydrogen storage tank, hydrogen pipeline, weighing sensor and control box, hydrogen pipeline is divided into the former section and the latter section, and hydrogen pipeline former section is connected with hydrogen storage tank, hydrogen pipeline latter section is divided into the outer sphere inflation pipeline and the inner sphere inflation pipeline, and two are communicated with the outer sphere of double -layer sounding balloon and the inner sphere through the outer sphere inflation hose, the inner sphere inflation hose respectively, and are equipped with the outer sphere pipeline solenoid valve, the inner sphere pipeline solenoid valve respectively, weighing sensor is fixed on the inflation platform and is connected with double -layer sounding balloon through sounding special rope, and weighing sensor is used for measuring net lifting force, and net lifting force real -time signal is transmitted to control box, control box is used for receiving, display net lifting force to real -time control outer sphere pipeline solenoid valve and the opening and close of inner sphere pipeline solenoid valve according to net lifting force size. The utility model can realize the accurate control to the balloon net lifting force in the process of the flat drift double -layer sounding balloon inflation.

This utility model relates to auxiliary equipment in the machinery manufacturing industry, and discloses a grease dispensing pressure tank, including an outer tank with a barrel lug fixedly connected to its exterior. An auxiliary fixing mechanism is slidably connected to the exterior of the outer tank, and a pressing mechanism is fixedly connected to its interior. A top-layer assembly is slidably connected to the top of the outer tank. The pressing mechanism includes an inner tank, with its bottom fixedly connected to the interior of the outer tank. A sealing ring is slidably connected to the interior of the inner tank, and a piston is fixedly connected inside the sealing ring. An exhaust port is provided inside the piston, and an oil outlet assembly is fixedly connected to the top of the piston. This utility model allows non-flowing grease to be smoothly dispensed. A safety valve automatically releases pressure when it is too high, preventing the risk of explosion due to exceeding the safety pressure threshold. A pressure-reducing valve allows for manual pressure release when not in use, ensuring safe and convenient operation.
