Model B

* excluding air capacity: the need to add the evacuation device * used for superheated steam *limit to the back pressure: the back pressure of the inlet pressure is 80% * the steam loss: can surface heat insulation *Saturated water capacity: to drain the saturated water, there by obtaining the highest thermal efficiency * drainage mode: continuous drainage, water that is discharged, there will be no water accumulation in the heating equipment * steam pressure change on the impact of steam traps: can be adapted to a large and sudden pressure changes, the floating ball can adjust the opening of the drainage valve seat hole, the work of continuous, stable performance
