A27W type spring micro-opening safety valve is suitable for working temperature ≤ 200 ℃ corrosive media equipment or pipeline, as overpressure protection device.
Structure and Working Principle
- This valve consists of valve shell, valve seat, valve stem, valve flap, spring and other parts.
- This valve when not working or not reached the specified working pressure, relying on the pressure of the spring will valve flap tightly pressed on the valve seat to keep it sealed, when the working pressure exceeds the specified working pressure, the valve flap automatically open, to exclude the medium, so that the pressure does not continue to rise, to ensure that the use of safety.
