CS45H inverted bucket steam trap

CS45H inverted bucket steam trap

Introduction to CS45H inverted bucket steam trap: The inverted bucket trap is based on the principle of phase change, relying on the different thermodynamic principles of the flow rate and volume change of steam and condensate when passing through, so that different pressure differences are generated up and down the valve plate to drive the valve plate to open and close the valve. Because the working power of thermodynamic traps comes from steam, the waste of steam is relatively large. The structure is simple, the water hammer is resistant, the maximum back is 50%, there is noise, the valve plate works frequently, and the service life is short. The inverted bucket trap has thermodynamic type (disc type), pulse type, orifice type.

CS45H inverted bucket steam trap

Product structure features of inverted bucket steam trap:
All moving parts in the inner cavity are made of stainless steel, which is resistant to wear and corrosion. Since steam cannot reach the valve seat hole sealed by water, there is no steam loss and high efficiency and energy saving. The floating bucket is inverted, it will not be damaged or crushed, it is not afraid of water hammer, and it has a long life.
The top of the inverted barrel is provided with a vent hole. The continuous air exhaust performance is good, and the cold hysteresis and air blockage will not be formed.
The inverted bucket steam trap is not affected by back pressure and can work well under high back pressure.
The inverted bucket steam trap does not work reliably. There are only two moving parts (the lever-and the inverted bucket), so there will be no jamming.
The valve seat and disc are on the top of the valve, and the disc can let dirt pass through during the switch. It has good self-cleaning performance and is free of dirt.

Working principle of inverted bucket steam trap:
The inverted bucket steam trap does not use the working principle of the density difference between condensate water and steam. The internal structure is connected to the inverted bucket by a lever system to overcome the steam pressure switch. The inside of the inverted bucket trap is an inverted bucket as a liquid level sensitive part. The bucket opens downwards. When the device is just started, air and low-temperature condensate appear in the pipeline. At this time, the trap is fully open, and the air and low-temperature condensate are quickly discharged, and the device quickly raises the temperature. When steam enters the inverted bucket, the inverted bucket generates upward buoyancy, and the inverted bucket is connected to the lever to drive the valve core to close the valve. There is a small hole in the inverted bucket, which can automatically exhaust air. When a part of the steam is discharged from the small hole, the other part of the steam produces condensate. The inverted bucket loses buoyancy and sinks. The inverted bucket is connected to the lever to drive the valve core to open the valve. When the steam enters the inverted bucket again, the valve is closed again, and the cycle works, intermittently draining water.
