Thermal Power Drain Valve

The working principle of a thermal power drain valve is that when air and condensed water enter the drain valve, the valve disc is pushed away from the valve seat under the action of the working pressure difference, quickly eliminating the air and condensed water. Thermodynamic drain valves are mainly based on the principle of phase change, relying on the different thermodynamic principles of the flow rate and volume changes of steam and condensed water passing through, to generate different pressure differences above and below the valve plate, and drive the valve plate to open and close the valve. Due to the fact that the working power of the thermal power drain valve comes from steam, steam waste is relatively large. Simple structure, shock resistant, maximum back of 50%, noisy, frequent valve operation, short service life. The thermal power type drain valves produced by Shanghai Meiyanyi Pump Valve include thermal power type (disc type), pulse type, orifice plate type, etc. These valves should generally be installed horizontally in pipelines.
