The technical scheme adopted by the utility model for solving the technical problem is as follows: the utility model provides a look selects quick-witted solenoid valve to move iron core rubber coating structure, is including moving the iron core move the iron core middle part and set up the gas pocket that link up its both ends, move the iron core outer wall and be equipped with the rubber coating boss, rubber coating boss lateral wall bonds and has the rubber coating, has seted up rubber coating bodiness groove at the rubber coating end foot position that moves the iron core outer wall.
Further, the encapsulation is made of hydrogenated nitrile rubber.
Further, the movable iron core is installed in the electromagnetic valve body, and the rubber coating is clamped with the inner wall of the valve body and the clamping position is located between the air inlet and the air outlet of the valve body.
Furthermore, the outer wall of the movable iron core is also provided with two sealing bosses positioned on one side of the rubber coating, and a sealing ring groove is formed between the two sealing bosses.
Furthermore, one end of the movable iron core is provided with a balance limit table positioned at the other side of the rubber coating, a sealing boss is also arranged adjacent to the balance limit table, and another sealing ring groove is formed between the sealing boss and the balance limit table.
Further, the air holes comprise ventilation through holes and ventilation lightening holes which are communicated, and the diameters of the ventilation through holes are smaller than the diameters of the ventilation lightening holes.
Furthermore, a movable iron core sealing ring is arranged in each sealing ring groove.
Has the advantages that:
1, the encapsulation has good sealing performance, low processing cost and good consistency;
2, the structure is simple, the end face sealing performance is ensured, and the service life is long;
3, the sealing stroke is short, the response speed of the electromagnetic valve is high, and the flow of the vent hole is increased.
Drawings
FIG. 1 is a cross-sectional view of the structure of the present invention;
fig. 2 is a diagram of the application of the present invention.
Reference numbers in the figures: 1. the movable iron core comprises a movable iron core body, 2 rubber coating, 3 sealing ring grooves, 4 balance limiting tables, 5 ventilation through holes, 6 ventilation lightening holes, 7 rubber coating thickening grooves.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in detail with reference to the accompanying drawings and specific embodiments.
Example 1
A core cladding structure of a solenoid valve of a color selector is disclosed, as shown in figure 1, an air hole penetrating through two ends of a movable iron core 1 is formed in the middle of the movable iron core, the air hole comprises an air through hole 5 and an air lightening hole 6 which are communicated, and the diameter of the air through hole 5 is smaller than that of the air lightening hole 6. At the moment of the power failure of the electromagnetic valve, the pressure flowing into the movable iron core from the air hole acts inside the movable iron core, and the electromagnetic valve can be quickly closed by matching the force of the spring sleeved on the outer wall of the movable iron core, so that the precision and the safety are ensured.
Move 1 outer wall of iron core and be equipped with the rubber coating boss, rubber coating boss lateral wall bonds and has rubber coating 2, has seted up rubber coating bodiness groove 7 at the 2 end foot positions of rubber coating of moving 1 outer wall of iron core position. The rubber coating 2 is made of hydrogenated nitrile rubber, the cross section of the side wall of the rubber coating boss is trapezoidal, the rubber coating 2 is identical with the shape of the rubber coating boss, and the rubber coating thickening groove 7 is used for filling the rubber coating 2 to enable the thickness of the rubber coating 2 to meet the requirement.
The outer wall of the movable iron core 1 is also provided with two sealing bosses positioned on one side of the rubber coating 2, and a sealing ring groove 3 is formed between the two sealing bosses. One end of the movable iron core 1 is provided with a balance limiting table 4 positioned at the other side of the rubber coating 2, the balance limiting table 4 is used for limiting the movable iron core 1 to only do axial movement in the valve body, a sealing boss is also arranged adjacent to the balance limiting table 4, and another sealing ring groove 3 is formed between the sealing boss and the balance limiting table 4; and a movable iron core sealing ring is arranged in each sealing ring groove 3.
Mounting positions: the movable iron core 1 is arranged in the electromagnetic valve body, and the rubber coating 2 is clamped with the inner wall of the valve body and the clamping position is positioned between the air inlet and the air outlet of the valve body.
