The utility model is described in further detail below in conjunction with drawings and Examples:
As shown in the figure, the utility model comprises body, described body comprises valve seat 10, be located at the coil 2 on the valve seat 10, be located at valve core housing 14 and the spool 3 of being located in the valve core housing 14 in the coil 2, right side, described valve seat 10 bottom is valve water intake 7, described valve seat 10 lower left side are valve water outlet 13, in the bottom of valve core housing 14 and between coil 2 and valve seat 10, be provided with plastic diaphragm 6 and elastomer diaphragm 12, described plastic diaphragm 6 is located at the top of elastomer diaphragm 12, and plastic diaphragm 6 and elastomer diaphragm 12 are fixed in one, described spool 3 bottoms are provided with rubber seal 4, be provided with valve core reseting spring 1 on the top of spool 3, described plastic diaphragm 6 right parts are provided with pressure control cavity water intake 8, described plastic diaphragm 6 middle parts are provided with pressure control cavity water outlet 11, described pressure control cavity water intake 11 is provided with the turriform spring with cleansing pin facing to valve water outlet 13 between described plastic diaphragm 6 and the valve core housing 14.
Described spool 3 and valve core housing 14 are for being slidingly matched.Described valve core reseting spring 1 bottom peaks on the upper tip of spool 3, and described valve core reseting spring 1 top peaks on the inwall of valve core housing 14.Described turriform spring with cleansing pin comprises cleansing pin part 9 and turriform spring main body 5, and described cleansing pin 9 is " 7 " character form structure, and described cleansing pin stretches out to one section of minor diameter on turriform spring major diameter one end cylindrical, and is vertical with end face, parallel with center line.
The longitudinal edge bottom of described " 7 " font cleansing pin 9 places in the pressure control cavity water intake 8.The horizontal edge of described " 7 " font cleansing pin 9 is located on the inwall of valve core housing 14 bottoms.Described spool 3 is soft iron core.Described elastomer diaphragm 12 is provided with the first fixed hole 15 and the second fixed hole 16, described plastic diaphragm 6 bottoms are provided with the first gland 17 and the second gland 18, and described the first gland 17 and the second gland 18 are individually fixed in the first fixed hole 15 and the second fixed hole 16.
The explanation of the utility model working principle:
This patent has increased a turriform spring with cleansing pin on the general solenoid valve basis, turriform can allow the spring-compressed be flat pattern, and height dimension is minimum, stability is best, makes the solenoid valve compact overall structure; Turriform cleansing pin spring 5 is pressed on plastic diaphragm 6, elastomer diaphragm 12 on the water outlet of valve seat 10, increases sealing load, prevents the situation of leaking of valve; Cleansing pin 9 on the turriform cleansing pin spring 5 passes the pressure control cavity water intake 8 on the plastic diaphragm 6, plastic diaphragm moves up and down valve in the working procedure opening, close, cleansing pin 9 is just dredged the pressure control cavity water intake, can prevent effectively that impurity retaining pressure control chamber water intake in the sealing causes pressure control cavity can't intake and the solenoid valve fault out of control that causes.
When switching on, coil 2 assemblies produce magnetic field, drive the pressure control cavity water outlet 11 that moves away on the soft iron core 3, rubber seal 4 on the plastic diaphragm 6, the interior water of pressure control cavity this moment flows into valve water outlets 13 by pressure control cavity water outlet 11, make the pressure decreased in the pressure control cavity, plastic diaphragm 6, elastomer diaphragm 12 move under water intake 7 pressure-actings, and valve opening water intake 7 current flow out valve body through water outlet 13.This moment, plastic diaphragm upward pressure control chamber water intake 11 produced displacement with turriform cleansing pin spring section cleansing pin 9, and cleansing pin has just carried out once dredging to plastic diaphragm upward pressure control chamber water intake 11; When coil 2 assemblies cut off the power supply, on soft iron core 3, the rubber seal 4 pressure control cavity water outlet 11 that are pressed under Returnning spring 1 acts on the plastic diaphragm 6, block pressure control cavity water outlet 11, pressure chamber pressure raises, plastic diaphragm 6, elastomer diaphragm 12 move down valve closing.This moment, plastic diaphragm upward pressure control chamber water intake 11 produced displacement with turriform cleansing pin spring section cleansing pin 9, cleansing pin has just carried out once dredging to plastic diaphragm upward pressure control chamber water intake 11, so the every open and close of valve once, cleansing pin has just been dredged 2 times plastic diaphragm upward pressure control chamber water intake 11.Guaranteed that effectively the unimpeded of pressure control cavity water intake 11 do not stop up.
