free semi-float steam trap
Other Products
I. Introduction:
The CS45H free semi-float steam trap is one of the most reliable mechanical steam traps in terms of working performance. Its internal structure has only one semi-float bucket as the moving part, with the opening facing downward. The outer circle of the semi-float bucket is finely ground, and the entire spherical surface can serve as a sealing surface. It has a long service life, is resistant to water hammer, has no wearing parts, is trouble-free, durable, has no steam leakage, and provides good energy-saving effects. The free semi-float steam trap is used in steam heating equipment and steam pipeline network condensate recovery systems. When the steam inside the bucket turns into condensate, the bucket loses buoyancy and sinks, opening the valve to quickly discharge the condensate. When steam enters the bucket again, the valve closes, operating intermittently or continuously. Since the valve seat is isolated by a water seal, steam and water are separated, resulting in no steam leakage during operation.
II. Product Features:
1. When combined with a lever mechanism, it can be made into a high-pressure valve.
2. The shield-shaped float is resistant to water hammer; there is no overflow vent on the upper part of the bucket, which can effectively prevent steam lock and air blockage.
3. Reliable steam-water separation: Steam and water enter from the lower part of the valve through a U-shaped channel, and the inside of the valve is always in a sealed state, effectively preventing steam leakage.
4. High back pressure rate: 90%
5. All internal parts are made of stainless steel and installed on the valve cover, making maintenance extremely convenient.
6. Equipped with a large-displacement double-valve seat differential pressure mechanism and SCCV closing system, it has a small volume and large displacement.
7. It is highly adaptable to the condensate generation rate, enabling both intermittent and continuous discharge.
III. Working Principle:
This product operates on the principle of the density difference between condensate and steam. Its internal structure consists of an inverted bucket connected by a lever system, which overcomes steam pressure to switch the inverted bucket-type steam trap. The inverted bucket is the liquid level-sensitive component, with its opening facing downward. When the device starts up, air and low-temperature condensate appear in the pipeline, at which point the steam trap is fully open, quickly discharging air and low-temperature condensate, and the device quickly warms up. When steam enters the inverted bucket, the inverted bucket generates upward buoyancy, and the inverted bucket connects to the lever to drive the valve core to close the valve. A small hole is opened on the inverted bucket for automatic air exhaust. When part of the steam is discharged through the small hole and another part of the steam forms condensate, the inverted bucket loses buoyancy and sinks, and the inverted bucket connects to the lever to drive the valve core to open the valve. When steam enters the inverted bucket again, the valve closes, and it operates in a cycle, discharging water intermittently.
