Introduction Thermal power type thermal power type drain valve

       Thermal power type drainage valve according to the principle of phase transformation, the different thermodynamic principle by the steam and condensate flow rate and volume change, the valves have different pressure, driving the valve plate valve. Because the hot steam trap valve working power source for steam, so relatively large waste of steam. Simple structure, water hit, the biggest back to 50%, there is noise, the valve work frequently, short service life.

       Hot steam trap valve

    Hot steam trap valve has a valve, is a sensitive parts is the implementation of action items. According to the differentthermodynamic principles to the passage of steam and condensateflow rate and volume changes, the valves have different pressure,driving the valve plate valve. The steam leakage rate of 3%, the undercooling of 8 ℃ -15 ℃.

     When the device starts, the pipeline appears condensate cooling,condensation of water pushed by the pressure valve, rapid discharge. When the condensation of water discharge is completed,the subsequent emission of steam, due to condensation of watervapor than the volume and velocity of large, the valves havedifferential pressure, the valve closed quickly in the suction flow rate of steam. 

      When the valve is closed, both sides of the valve under pressure, the valve plate below the force area is less thanthe force area, due to trap steam room, the pressure from the steam pressure, so the valve is greater than the force above the following, the valve closes tightly. When the drain valve steam room steam condenses into water cooling, steam room, the pressure disappears. The condensed water by pushing the valve working pressure, condensation water continued to discharge, cycle work,intermittent drainage.
