Product Overview of Thermodynamic Steam Trapby Jeremy Liang SEO specialist
Thermodynamic steam trap has an active valve sheet inside. It is both a sensitive part and an implementation-of-action piece. According to the different thermodynamic principles of flow rate and volume change when the steam and condensate water pass through, the pressure difference is generated on the valve sheet to drive the opening and closing of the valve. The gas leakage rate is 3%, the undercooling is 8 to 15 degrees Celsius.
When the device starts, cooled condensate water appears on the pipeline. The condensate water pushes open the valve sheet with operating pressure for rapid discharge. When the condensate water discharge is completed, the steam is subsequently discharged. Since the volume and flow rate of steam is larger than those of condensate water, pressure difference is generated on the valve sheet, which is quickly closed under the suction force of the flow rate of the steam. When the valve sheet is closed, it is subject to pressure from both sides. The force bearing area in the lower part of the valve sheet is smaller than that in the upper part of the valve sheet. Since the pressure inside the steam trap chamber comes from the steam pressure, the upper part of the valve sheet bears more force than the lower part of the valve sheet, leading to the tight closure of the valve sheet.
When the steam inside the steam chamber of the steam trap is cooled down into condensate water, the pressure in the steam chamber disappears. The condensate water pushes away the valve sheet with operating pressure, and the condensate water is further discharged, which forms a cycle of operation and an intermittent drainage.
