working principle
The lever floating ball trap uses the principle of buoyancy and the principle of leverage to raise or lower the float through the change of liquid level, and the float drives the lever to make the valve disc leave or contact the valve seat to open, drain, and close.
The role of steam. The automatic air exhaust valve can automatically eliminate non-condensable gas, which is very sensitive, high in work quality, and long in service life. Continuous drainage, drain when there is water, the minimum supercooling degree is 0℃
