Product introduction of cs15h-16 internal thread free semi floating ball drain valve

Free semi floating ball steam trap is one of the most reliable mechanical traps. Its internal structure only has a semi floating ball barrel as a moving part, with the opening facing down. The outer circle of the semi floating ball barrel is finely ground, and the whole spherical surface can be a sealing surface. It has a long service life, can resist water hammer, no wearing parts, no fault, durable, no steam leakage, and good energy-saving effect. Free semi floating ball steam trap is used for steam heating equipment and condensate recovery system of steam pipe network.

working principle

The free semi floating ball steam trap has only one semi floating ball barrel as the movable part, with the opening facing down. The barrel is both a hoist and a seal. When the device is just started, the air and low-temperature condensate in the pipeline enter the drain valve through the launching pipe. The bimetallic sheet emptying element in the valve pops the ball barrel open, the valve opens, and the air and low-temperature condensate are discharged quickly. When the steam enters the ball barrel, the ball barrel generates upward buoyancy. At the same time, the temperature in the valve rises, the bimetallic sheet emptying element shrinks, the ball barrel floats to the valve port, and the valve closes. When the steam in the drum turns into condensate, the drum loses its buoyancy and sinks down. The valve is opened and the condensate is discharged quickly. When the steam enters the ball barrel again, the valve will be closed again and work intermittently and continuously. Since the valve seat is in the water seal isolation, the water vapor is separated, and there is no steam leakage during operation.
