Location:Home / Product / Drain valve / free-ball float steam trap CS41H
The structure of the free floating ball steam trap is simple, with only a finely ground stainless steel hollow floating ball inside. It is both a float and an opening and closing component, with no vulnerable parts and a long service life. When the device is first started, air and low-temperature condensed water appear in the pipeline. The manual exhaust valve can quickly remove non condensable gases, and the drain valve begins to work. The low-temperature condensed water flows into the drain valve, and the liquid level of the condensed water rises. The float rises and the valve is opened. The device quickly raised the temperature, and before the temperature inside the pipeline reached saturation temperature, the automatic exhaust valve had already closed; The device enters normal operation, the condensed water decreases, the liquid level drops, and the float adjusts the valve hole flow rate with the rise and fall of the liquid level; When the condensed water stops entering, the floating ball approaches the valve seat with the flow of the medium and closes the valve. The valve seat of the free floating ball steam trap is always below the liquid level, forming a water seal and no steam leakage.
