Structural characteristics and working principle of inverted bucket steam trap

inverted bucket steam trap uses the working principle of the density difference between condensate and steam. Its internal structure is to connect the inverted bucket by the lever system to overcome the steam pressure switch. Inside the inverted bucket steam trap, an inverted bucket is a liquid level sensitive part, and the opening of the inverted bucket is downward. When the device is just started, I. structural characteristics of inverted bucket steam trap product

all moving parts in the inner cavity are stainless steel, wear-resistant and corrosion-resistant

. Since the steam cannot reach the valve seat hole sealed by water, there is no steam loss, which is efficient and energy-saving

. The floating bucket is upside down, will not be damaged and flattened, is not afraid of water hammer, and has a long service life

. The top of the inverted barrel is provided with an exhaust hole. The continuous air exhaust performance is good, and cold hysteresis and air blockage will not be formed

. It is not affected by the back pressure of the system solution from the research and development of new water-based PU coated fabrics to the range production provided by Bayer materials technology for brands, and it can work well under high back pressure

. It works reliably. There are only two moving parts (lever and inverted barrel), so it will not be blocked

. The valve seat and disc are on the top of the valve, and the disc can allow dirt to pass through in the switch, which has good self-cleaning performance and no dirt problems

II. Working principle of inverted bucket steam trap

inverted bucket steam trap uses the working principle of the density difference between condensate and steam. Its internal structure is that the inverted bucket is connected by a lever system to overcome the steam pressure switch. Inside the inverted bucket steam trap, an inverted bucket is a liquid level sensitive part, and the opening of the inverted bucket is downward. When the device is just started, air and low-temperature condensate appear in the pipeline. At this time, the drain valve is fully open, the air and low-temperature condensate are discharged quickly, and the device will soon raise the temperature. When the steam enters the inverted bucket, the inverted bucket generates upward buoyancy, and the connecting lever of the inverted bucket drives the valve core to close the valve. A small hole is opened on the inverted bucket, which can automatically exhaust air. When some steam is discharged from the hole, another part of the steam produces condensate, the inverted bucket loses buoyancy and sinks. The connecting lever of the inverted bucket drives the valve core to open the valve. When the steam enters the inverted bucket again, the valve will be closed again, working circularly and draining water intermittently
