Brand:GOOLE
Origin:China Zhejiang
Product detail: Brief Introduction.
Advantages.
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.
By the action of buoyancy, the position of floating ball changes with the water level of condensation water and adjust the opening of valve seat automatically, continue to discharge condensation water, when the condensation water stops, the floating ball fall onto bottom by gravity, then close opening of drain valve. The opening of drain valve is below the water lever, and so the water is separated from steam automatically, and form water seal without steam leakage.
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.
