the utility model discloses technical scheme's further improvement lies in: the water flow does not directly enter the filter element, but enters the water inlet valve through the water inlet and enters the filter element.
The utility model discloses technical scheme's further improvement lies in: the sliding valve core is provided with three guide posts which are uniformly distributed on the circumference.
The utility model discloses technical scheme's further improvement lies in: the upper part and the lower part of the sliding valve core are provided with replaceable sealing gaskets.
The utility model discloses technical scheme's further improvement lies in: the blowdown valve casing is provided with three guide grooves which are uniformly distributed on the circumference.
The utility model discloses technical scheme's further improvement lies in: the spring pressure adjusting plug can adjust the spring compression force to adapt to different irrigation pressures.
Since the technical scheme is used, the utility model discloses the technological effect who gains has:
the utility model discloses ingenious utilization is irrigated discontinuity characteristics and the water pressure in the irrigation pipe, has realized that every irrigation cycle all carries out full-automatic back flush that need not outside power to the filter, has prolonged the life of filter, has improved irrigation quality and irrigation efficiency.
The utility model discloses simple structure is ingenious, reasonable in design, and convenient operation reduces the consumption, and safety has improved production efficiency.
