Abstract
The utility model discloses a movable iron core of a solenoid valve, which has a cylindrical shape, the movable iron core is divided into a front part and a rear part in the axial direction, the diameter of the rear part is smaller than that of the front part, and a step surface is formed between the front part and the rear part; the movable iron core is sleeved with the movable iron core, and the movable iron core is sleeved with the movable iron core. The utility model discloses a straight spring at rear portion need not move the iron core periphery and provide the support position to make the iron core include that the spring is cylindrical on the whole, can not produce the physical contact on the face of cylinder with the coil, consequently do not have the motion to interfere, also more nimble on the holistic design scheme of solenoid valve.
Description
Technical Field
The utility model belongs to the technical field of the solenoid valve, especially, relate to solenoid valve movable iron core.
Background
The miniature energy-saving electromagnetic valve is a commonly used electromagnetic valve and is generally matched with an air cylinder for use, wherein a movable iron core is an important part of the miniature energy-saving electromagnetic valve, reciprocates under the combined action of a coil and a return spring, and is matched with the air cylinder for use through different working positions. The movable iron core of the electromagnetic valve in the prior art has a cylindrical shape, and the axis part of the movable iron core is provided with a hollow channel for installing a sealing element; a neck portion having a diameter smaller than the overall diameter is formed adjacent one end face for receiving the coil spring. The movable iron core has the disadvantages that the spring placed at the neck part is necessarily provided with a supporting position which is necessarily arranged at the periphery of the movable iron core, so that a gap is necessarily reserved between the movable iron core and a peripheral component (generally a coil), and if the gap is used as an air passage, a part of the spring is blocked on the air passage, and the ventilation effect is influenced; if this gap is not utilized, space is wasted.
Disclosure of Invention
The utility model aims at providing a novel solenoid valve moves iron core.
Therefore, the utility model discloses a technical scheme be like this: the movable iron core of the electromagnetic valve has a cylindrical shape and is characterized in that: the movable iron core is axially divided into a front part and a rear part, the diameter of the rear part is smaller than that of the front part, and a step surface is formed between the front part and the rear part; the movable iron core is sleeved with the movable iron core, and one section of the movable iron core is abutted to the step surface.
Further, the diameter of the rear periphery is equal to the diameter of the front portion after the spring is added.
The utility model discloses a straight spring at rear portion need not move the iron core periphery and provide the support position to make the iron core include that the spring is cylindrical on the whole, can not produce the physical contact on the face of cylinder with the coil, consequently do not have the motion to interfere, also more nimble on the holistic design of solenoid valve.
Drawings

Fig. 2 is a sectional view of the present embodiment.
Detailed Description
See fig. 1. The movable iron core 1 in the prior art is generally cylindrical, a neck 15 is formed near the front end, the diameter of the neck is smaller than that of the movable iron core, the spiral spring 3 is sleeved, the smaller end of the spiral spring 3 is clamped into the front step surface of the neck, and the larger end of the spiral spring is exposed out of the neck and used for supporting the periphery of a coil in a matched mode. The axial line part of the movable iron core 1 is hollow and is filled with a sealing element 2.
See fig. 2. The movable iron core 1 of the present embodiment is generally cylindrical, and is composed of a front portion 11 and a rear portion 12, wherein the diameter of the front portion 11 is larger than that of the rear portion 12, and a step surface 13 is formed at the junction of the front portion 11 and the rear portion 12. The rear part 12 is externally sleeved with a straight spring 3, one end of the spring 3 is propped against the step surface 13, and the outer diameter of the spring is equal to the diameter of the front part 11.
Claims (2)
1. The movable iron core of the electromagnetic valve has a cylindrical shape and is characterized in that: the movable iron core is axially divided into a front part and a rear part, the diameter of the rear part is smaller than that of the front part, and a step surface is formed between the front part and the rear part; the movable iron core is sleeved with the movable iron core, and the movable iron core is sleeved with the movable iron core.
2. The solenoid valve plunger according to claim 1, wherein: the diameter of the spring is equal to that of the front part after the spring is added on the periphery of the rear part.
