CS69H, CS49H type disc steam trap works: 

 Disc steam trap is the use of thermal dynamics, when the condensate drain is low, evaporation will occur the second time, and viscosity, sealing, etc. there are differences with the steam-driven hoist pieces. 
 Disc steam trap is based on Bernoulli's principle of thermal power, steam and condensate using the different thermodynamic properties, kinetic and potential movement caused by pressure changes. The valve moves up and down the pieces of pressure changes, start valve open and close, so as to achieve the purpose of blocking gas drainage. : 

 1, with steam or air heat units, independent of ambient temperature influence, reduce the operating frequency, extending life. 
 2, equipped with filters and sewage. 
 3, the valve is sensitive and reliable, large displacement. 

 The trap has a valve, is sensitive to the implementation of the action pieces and parts. When the device starts, condensate pipe cooling off, open condensate valve by operating pressure, rapid discharge. When the condensed water discharge is completed, the steam into the trap, the rapid expansion of the volume of steam, steam condensate flow rate than the large, so that the upper and lower valves have pressure, the steam valve in the suction flow rapidly off. When the valve is closed and the valve by the pressure on both sides of the valve area is less than the force below the top of the force area, due to trap steam inside the pressure chamber from the vapor pressure, so the valve is greater than the force above the following, valve tightly closed. When the steam room inside the steam trap into the condensate temperature, vapor pressure inside the chamber disappear. Condensation of water pushed by the working pressure valves, condensate and continue to discharge, cycle work, intermittent drainage.
