Auto water trap

Description

Auto water trap is usually used to drain the water of the port where is lower, segregator, gas store pot and the bottom of gas filter. It is installed where it is not easy to drain the sewage with manpower, for example high, low or narrow place and especially where using large gas or drain water continually. It is can prevent the compressor air from re-polluting by water condensate. Drain automatically, no needs manual operation Dustproof; durable and reliable Standard parts are equipped with body case.

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.
