Background

The drip preventer is an automatic valve used by an automatic irrigation spray head, and can be opened only by a certain pressure, so that the problem that the spray head drips due to residual water pressure in a pipeline after an irrigation system is closed, and the irrigation effect is affected can be avoided. The existing drip-proof device technology realizes opening and closing by using silicon sheets or springs to be pressed and deformed, and is not sensitive to the change of water pressure. Meanwhile, the technology of the silica gel sheet is subjected to compression deformation, the hardness of the silica gel raw material is difficult to control, often the individual difference of products is obvious, and the water pressure required by opening and closing of the drip preventer is high or low; the technology of spring compression deformation is that the deformation of the spring is in linear relation with the change of water pressure, and usually after the water pressure reaches the opening or closing pressure, the drip preventer is fully closed to fully opened or fully opened to fully closed, and a change process exists in the middle, so that the drip is easy to occur in the process due to the fact that the opening and the closing are not rapid enough. In the existing drip-proof device technology, the flowing path of water flow in the drip-proof device is more tortuous, and has certain pressure loss, so that the efficiency of the whole irrigation system is affected to a certain extent, and the problems of insufficient system pressure, poor nozzle effect and the like are caused.
