Water in geopark

Radostna studanka

Spring well is located since 1841 in the chapel, which is now enclosed wooden fence. The water from the spring on yield 1.5 l / sec supplying three houses in the village. It was used ram to delivers water to Rieger’s cottage on the Kozákov hill (about 120 meters higher). Ram was invented by Joseph Michel Montgolfier, one of two French brothers, who also constructed the Montgolfier balloon. Water emerges from the ram to the tank (1), at its bottom there is hydrostatic pressure. Leads from the tank pipe of sufficient diameter sieve protected from dirt, so that the pipe is still free (2). Water flows through the drop pipe ram valve (3) with the weights (4), which exerts a force greater than the hydrostatic pressure of the water. When the water reaches the required pressure, clogged ram valve seat. Pressure, which is the impact on the ram valve creates, opens the discharge valve (5) in the reservoir (6), which is filled with air, and the water in it begins to flow. Compressed air in the reservoir displaces the water line (7) until Rieger cottage (8). When the pressure is released the water column, the discharge valve without pressure drops and closes the opening of the pipes leading to the reservoir. Hydrostatic pressure hold valve ram loaded, and when the energy is exhausted, the ram valve decreases. Water begins to flow over the saddle again with trkacím valve. Gathering pace up again pressed the valve on the seat. The whole process is repeated. In the vicinity of the source of the steep rocky subsoil growing European beech (Fagus sylvatica), sycamore maple (Acer pseudoplatanus), ash (Fraxinus excelsior), silver birch (Betula pendula), rowan (Sorbus aucuparia) and Norway spruce (Picea abies) . The forest vegetation thrives as fungi of the genus třepenitka (Hypholoma).
