Abstract
The utility model discloses a filter mechanism and hydropower station speed governing system pressure tank exhaust pressure relief silencing device, including valve component, including valve body, set up in the connecting shaft of valve body inner wall, set up in the valve core of connecting shaft bottom and set up in the connecting pipe of one side of valve body, and, set up in the air release component of connecting pipe outer wall, including air release pipe and set up in the air inlet of air release pipe bottom. Through the synergies of multistage silencing structure and through the cooperation of air -tight exhaust piston and elastic part, the unit time gas flow is accurately controlled, the sharp noise that the high -speed airflow directly sprays produces is avoided, and the efficient, low -noise pressure relief process is realized.
