Description

Water inlet electromagnetic valve with flow limiting assembly Technical Field The utility model relates to a water inlet electromagnetic valve with a flow limiting component, which belongs to the categories of F16K 15/14 and F16K27/02. Background At present, the water inlet solenoid valve in the market generally controls the flow size of the water inlet valve during operation through a flow limiting valve assembly, the flow limiting valve assembly comprises a valve seat, a bonded flow limiting rubber cushion and a flow limiting column, the flow limiting rubber cushion can generate different deformations according to the heights of different flow limiting columns under different water pressures, the gap between the flow limiting rubber cushion and the flow limiting valve seat is changed, the water passing area is controlled, and then the flow size is controlled. For a water inlet valve with two or more water outlets, under high water pressure, water is easy to flush to the water outlet at the far end, so that the water outlet flow rate at one end far from the water inlet is larger, the water outlet flow rate at one end near to the water inlet is small, even no water is discharged, and stable flow rate cannot be generated. For terms and knowledge, unless indicated by the specification, see "IEC electric standard term dictionary (1 st edition 1992 of China Standard Press)," Electrical manufacturing Art "(1 st edition 1982 of mechanical industry Press)," mechanical engineering Manual ", and" Motor engineering Manual "(1 st edition 1978 and 2 nd edition 1997 of mechanical industry Press)," national standard GB/T21465-2008 "valve term", and national light industry Standard QB/T1291 "Inlet solenoid valve for automatic washing machine".
