Remote controlled hydroautomatic valve for irrigative systems with a pressurised water distribution system, on which its cylinder frontal surface is engraved an annular shaped channel 1. Placed in this channel is the exterior upper annular nose of a ring shaped formation arrangement intersected along the axis in four similar sections. The formed arrangement has on its lower part an inner annular nose and in the middle an outer annular channel, in which there is an elastic ring placed. Along the rod piston, which is assembled with the capability of movement inside the cylinder and the ring shaped formation arrangement, there is an upper and lower processed annular channel, as well as a percussion head right under the lower annular channel. Underneath the cone-shaped top of the cylindrical valve's weight that plays the role of a propelled lock for the disc's axial opening, a vertical cylindrical section is processed, whose diameter is smaller than the axial opening's diameter, and its lower part ends with frontal rubber gasket. |
