Description
Technical field
The present invention relates to the heating system dehydration measurement and control system of a kind of heating system dehydration Detection & Controling method and employing the method.
Background technology
The heating system of the occasions such as existing house and office comprises carries the water inlet manifold of thermal medium (hot water or steam) and the return main for thermal medium backflow to each heating user, the unit water inlet pipe of heating unit is connected described water inlet manifold and described return main with unit return pipe respectively by pipeline, usual heating unit has several, such as, be provided with some water inlet standpipes and return riser in building, often organize the user pipe of each floor on same plane position in parallel on standpipe, and different standpipe is connected in parallel on same horizontal endless tube, house steward connects each user pipe by endless tube and corresponding standpipe, realize the heating to whole building.
The improper dehydration of heating system mainly contains two reasons; one is discharge water from hot duct artificially; mostly occur on user's interior conduit; two is pipeline leakage; revealing due to user's interior conduit usually can by user's Timeliness coverage, and the lasting dehydration that therefore pipeline leakage causes has more on the pipeline of present open air (pipeline being mainly from total inlet valve to each unit inlet valve and each unit backwater valve to total backwater valve and facility).At present also not to the technology that this two kinds of dehydration modes effectively identify and monitor, often unnecessary loss can be brought because of dehydration to heating system.
Summary of the invention
In order to overcome the above-mentioned defect of prior art, the invention provides a kind of heating system dehydration Detection & Controling method and a kind of heating system dehydration measurement and control system adopting the method, with the dehydration of detection and control heating system effectively.
