1.Continues discharging saturation condensed water without accumulation, and so get the maximum thermal efficiency.
2.When steam pressure changes, the ball float can adjust the opening of valve seat without influence, and so it is stable.
3.With automatic and manual releaser, and so its exhaust performance is good without airlock and working is smooth without noise.
Working Principle.
a.When the device starts up,as the temperature of steam trap is low,sylphon temperature sensing element contracts,air vent hole (A) open,discharging the air inside continiously,realizing quick opening.
b.When condensed water flow into steam trap,air is discharged from air vent(A) automatically,float ball rises with level of condensed water,then condensed water is discharged from drain hole(B).
c.When hot condensed water and steam flow into steam trap,the liquid in sylphon expands under high temperature,air vent(A) close accordingly,float ball rise and down with the level of condensed water,discharging hot condensed water.
d.When condensed water stop flowing into the steam trap,float ball falls with level of condensed water and close the drain hole(B),as the drain hole is always under the level of condensed water,forming water sealing,no steam leaking.
Application.
By automation, speediness and continuing features, this valve is used for the steam heating equipment, condensation water recovery system and the place where needs removing condensation water at quick speed, and so stop steam leakage effectively and obtain optimum heating.
