Applications and structure description
GA49H-16C type DN40/50 impulse valve, also known as lever type safety valve, is mainly used for power plant boiler or steam pressure pipelines, the impulse valve may be complementary or used alone. When the vessel internal medium pressure exceeds the allowable value, the disc opens to exclude super-pressure steam, when the pressure drops to a certain value, the disc closes the valve rapidly by the heavy hammer of lever, to ensure the safe operation of equipment. The impulse valve consists of body, disc, seat, lever, heavy hammer, etc., its structural diagram is as follows: the main performance range: nominal pressure; 1.6Mpa; Nominal diameter: 40/50mm; shell intensity: 2.4Mpa; opening height: ≥ 9mm; working temperature: ≤ 350 ℃; applicable medium: steam, oil.
