Hydro-automatic water drain valve with freezing hydro-sensor operates in a manner that the water in the sensor (1), put in the place where the temperature first reaches zero degrees Celsius, freezes. The freezing of the distilled water, or its turning into ice (19) respectively, causes the increase of the volume and hydrostatic pressure in synthetic oil (4) of the sensor used for the valve activation. Sensor medium, i.e. distilled water (2) and the medium for tranferring pressure to activate the valve, i.e. synthetic oil, are directly connected through the pipe (3). To prevent damage resulting from freezing at zero degrees Celsius in containers (boilers, various containers, pipelines and the like), this invention provides technical solution using the valve with sensor which has no extra propulsion (operates without additional energy) and operates automatically using turning of the water to ice, and that, at the moment the temperature reaches zero degrees Celsius in the place where the sensor container (1) is installed. The increase of the volume of the distilled water, when turned to ice, causes the generation of the hydrostatic pressure in synthetic oil which is in the pipe of the sensor. The result thereof is shifting of the piston (6) which activates opening of the valve, providing passage for water from the container to the place appropriate for it, so the container remains completely empty. |
