Abstract
The utility model belongs to the technical field of an electric sprayer accessory, which concretely relates to a ball valve type water inlet valve and a pressure limiting valve of an electric sprayer. The utility model is composed of a three-way pipe, a valve core positioned in the cavity of an expansion pipe of the three-way pipe, a valve ball positioned on one end surface of a water outlet hole of a valve core, and a return spring, wherein the end surface of the water outlet hole of the valve core is provided with a groove and the groove is provided with a water stop ring. The water stop ring is provided with an extending inner brim of the same body, and the inner brim is extended to the end surface of the water outlet hole of the valve core and is jointed with the end surface of the water outlet hole of the valve core. The expanded range at least causes the valve ball to press the edge of the inner brim. During work, the valve ball does not directly contact with the water outlet hole of the valve core and indirectly contacts with the outlet hole of the valve core through the extending inner brim of the same body of the water stop ring. The water stop ring is made of soft plastics. Thus, the defect of size deviation or ovality of the existing valve ball can be eliminated for improving properties of the water inlet valve and the pressure limiting valve.
