U-shaped connector vital capacity and vital power resisting test instrument

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