Abstract

The invention discloses a U-shaped connector vital capacity and vital power resisting test instrument. Two vital capacity and vital power test instruments are connected through a pipe, a valve is arranged on the pipe, and a U-shaped connector is connected in parallel with the valve. Each vital capacity and vital power test instrument comprises a buoy and a water tank, and the buoys are arranged in the water tanks. Air inlet nozzles in the bottoms of the water tanks are connected with air blowing nozzles through hoses. Buoy rods with scales are inserted into the water tanks from rod sleeves with seal rings to be inserted into the buoys after passing through buoy valve seats, and valve plates are arranged at the ends. Springs are arranged at connection positions between rods with seal rings and the buoy valve seats to compress the buoy valve seats to form seals. Exhaust valves and water inlet units are arranged above the water tanks, and liquid level meters with scales are connected with the sides. By means of the test instrument, the structure is simple and reliable, opening and closing are achieved through cams and are convenient and reliable to operate; tensioning and reset is achieved through springs, and the cost is low; gas leakage can be prevented effectively through seal pads; vital capacity and vital power measuring can be performed, vital capacity and vital power resisting test can be performed, high entertainment is provided, and the application prospect is broad.
