The system consists of two parallel networks of tubular pipes: one main network and one supplementary network, at the beginning of which are assembled stop valves for the inflow and stoppage of water, as well as tubular branches for contact with the atmosphere. In addition, the system consists of hydro-automatic valves, pulsating hydro-pneumatic accumulators and artificial rain devices, where along the two tubular pipe networks, steady bases for artificial rain with artificial rain devices are installed, where the connection between them is achieved via two position gravitation valves using a freely moving cylindrical cap. |
