Abstract
The present invention is to provide a system and a method for effectively preventing that gases/heat from an outlet are ascending from a gully and form ice, in addition to effectively drain liquids through a gully. The present invention is obtained by arranging a float so that said float and a portion of the gully define a closable opening for through flow, further arranged such that the float is preventing gases/heat from the outlet to ascend up from the gully and form ice and/or so that the float prevents that gas is drawn into the gully.
Claims13
A gully system including a gully for draining a liquid to a drainage system, said gully system comprising:
- a float arranged so that the float and a portion of the gully define a closable opening for through flow, and
- arranged so that the float prevents gas from being drawn into the gully;
- wherein the gully system further comprises an actuator for controlling the float;
- means for controlling the float so that gas is not passing the float into the gully, said means comprising:
- a sensor for detecting that gas is drawn into the gully, and
- a control unit,
- wherein said means for controlling the float are arranged
- to control the actuator for opening by way of the float until gas is drawn into the gully, and
- to control the actuator for closing by using the float until gas is no longer drawn into the gully.
A method for controlling a gully system including a gully for draining a liquid to a drainage system, the gully system including a float arranged so that the float and a portion of the gully define a closable opening for through flow, wherein the gully system further comprises an actuator, the method comprising:
- having the actuator control the float to prevent gas or heat from an outlet to rise up from the gully and forming ice;
- the actuator being adjustable to:
- lift the float until gas is drawn into the gully;
- detect that gas is drawn into the gully;
- and
- lower the float until gas is no longer drawn into the gully.
