Condensation container for steel flue of oil, gas or solid-fuel heating system receiving condensation via valve head having sliding valve ball controlled by flue pressure

摘要

The condensation container (3,4) is coupled to a condensation collector and drainage pipe formed integral with the bottom end of the steel flue (1), via a relatively sliding pipe (2) fitted to the drainage pipe. The sliding pipe is provided with a valve head (6) with a sliding valve ball (8), releasing the flow cross-section for the condensation at normal pressure and blocking the flow cross-section upon an abnormal increased or reduced pressure in the flue.
