Thermodynamic hydrophobic type pneumatic valve

thermodynamic hydrophobic type pneumatic valve, pneumatic valve has an activity is a sensitive parts and action execution. According to the steam and condensate through a change in velocity and volume of different thermodynamic principle, the pneumatic valve and produce different pressure difference, pneumatic valve driven by pneumatic valve switch. Steam leakage rate %, super-cooling degree ℃ - ℃.
when the device is started, pipe cooling water, condensate pushed aside pneumatic valve plates by working pressure and rapid discharge. When the condensate discharge, vapor emissions, then because of the steam is greater than the condensate volume and velocity of flow, pneumatic valve and pressure difference, pneumatic valve in the steam flow rate under the suction of quickly shut down. When the pneumatic valve closing, pneumatic valve plates under pressure to both sides, the stress of the pneumatic valve below area is less than the stress area of the above, due to the hydrophobic pneumatic valve inside the dome from the steam pressure, the pressure of so aerodynamic force is greater than the following the above valve plates, pneumatic valve tightly shut. When the hydrophobic pneumatic valve inside the dome of steam condensate, the inside of the dome pressure disappear. The condensate by working pressure pneumatic valve plates, the condensate went on emissions, circulation work, intermittent drainage.
