Features and working principle of lever float trap
Lever floating ball trap has the characteristics of large displacement, long life, good energy saving effect, water hammer resistance, beautiful appearance, etc. It is widely used in process heat tracing, jacket heating kettle, reboiler and other equipment.

1. Scope of application:
Lever float traps can be used in industrial steam heating equipment, dryers, large heat exchangers, jacketed pots and other equipment. It is widely used in petroleum, chemical, metallurgy, papermaking, food, pharmaceutical, environmental protection and other industries.

2. Features:
The lever float trap has the advantages of unique and reasonable structure and high-precision internal parts. Specifically, its characteristics are as follows:
a. The valve body and bonnet are made of cast steel/forged steel.
b. All internal parts are made of stainless steel, and the wear allowance has been fully considered in the design of movable parts, which improves the service life of the trap.
c. The special flow channel design realizes no water hammer phenomenon.
d. The patented flexible closing system and micron-level precision closing system double guarantee no steam leakage and service life.
e. The built-in air exhaust valve ensures that there is no steam lock phenomenon.
f. The independent filter makes the trap work in a clean environment.
g. Choose different displacement curves according to the pressure.
h. The back pressure rate is as high as 95%.
i. The drain screw plug is designed at the bottom of the trap to ensure that the internal water is removed after stopping, and to prevent the floating ball from being damaged by freezing.

3. Working principle:
a. The working principle of the lever float trap is to rely on the difference of vapor and liquid density.
b. When the valve body is full of condensed water and non-condensable gas, the air exhaust valve opens to remove the non-condensable gas, and the floating ball moves upward to drive the valve core to open.
c. After draining the condensed water, the floating ball drives the valve core to move down and close the trap.
