The structural principle of the blowdown valve is to help the mechanical load seal acting on the valve disc directly by the force generated by the medium pressure The mechanical load acting on the blowdown valve disc mainly comes from the compression spring, which is almost a fixed mechanical load Although for the compression spring, the loaded spring force can be adjusted to achieve a good seal, but the seal pressure difference must be strong enough to ensure sufficient seal force, so as to achieve a seal when the blowdown valve operates normally The seal pressure difference shall also be less than the opening and closing pressure difference to ensure flexible opening
