basic information]
how it works: inverted hanging (set) bucket steam trap it is the use of condensed water and steam density difference principle of work, the internal structure is connected by the lever system upside down bucket to overcome the steam pressure switch inverted bucket trap inside is an inverted bucket for the liquid bit-sensitive parts, inverted bucket opening down. when the device is started, air and low temperature condensate appear in the pipe. 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 produces upward buoyancy, and the inverted bucket connects the lever to drive the valve to close the valve. inverted bucket has a small hole to open the air automatically, as part of the steam discharged from the hole, the other part of the steam condensate, inverted bucket loses its buoyancy to sink, inverted bucket connected to the valve lever to open the valve lever. when the steam into the inverted bucket again, the valve closed again, work cycle, intermittent drainage.
