free semi-float steam trap
I. Introduction:
The CS45H free semi-float steam trap is one of the most reliable mechanical steam traps in terms of operational performance. Its internal structure features only a semi-float bucket as the moving component, with the opening facing downward. The outer surface 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, operates without failure, is durable, has no steam leakage, and provides excellent 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 downward, opening the valve to quickly discharge the condensate. When steam enters the bucket again, the valve closes, enabling intermittent and continuous operation. 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 manufactured into a high-pressure valve.
2. The shield-shaped float is resistant to water hammer; there is no overflow vent hole at the upper part of the bucket, which can effectively prevent steam lock and air blockage phenomena.
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 mechanism and SCCV closing system, it has a small volume but large displacement.
7. It is highly adaptable to the condensate generation amount, enabling both intermittent and continuous discharge.
III. Working Principle:
This product operates based on the density difference between condensate and steam. Its internal structure consists of an inverted bucket connected by a lever system, which overcomes steam pressure. The inverted bucket-type steam trap has an inverted bucket as the liquid level sensing component, with the opening facing downward. When the device is just started, air and low-temperature condensate appear in the pipeline. At this time, the steam trap is fully open, and air and low-temperature condensate are quickly discharged, allowing the device to quickly rise in temperature. 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 downward, 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 this cycle repeats, resulting in intermittent drainage.
