Aluminum die casting
☆ Working principle:
1) When there is no pressure in the cup
The floater (5)will go down,valve(9)colse the pore(6),pistion (8)is pressed down by spring(11),then the condensed water passed the drain hole(12).
2) When there is pressure
When the pressure is larger than 1kgf/cm2,then the piston (8) conquers the spring and push up ward,and the drain hole closed,the inner of cup is isolated from the ourside.
3) When there is condensed water in the cup
When the quantity of condensed water reaches to a certain degree,the floater (5)will rise,and pore(6)open,the pressure enter into the inner chamber,then the piston (8)is pressed down by pressure and spring(11),and the condensed water passed the discharge pipe (13)and drain.
