Embodiment Construction

[0024] like figure 1 As shown, the electromagnetic valve with continuously adjustable spool movement of the present invention includes a valve casing 1, a coil 2 fixed in the valve casing 1, a wire 5 supplying power to the coil, and a static iron core 4 fixed on the casing 1 through a nut 6 And the moving iron core 3 placed in the static iron core 4. The valve core is riveted on the upper part of the moving iron core. In the case of no power supply, the spring presses the valve core and the moving iron core 3 to the bottom of the valve housing 1 together. When the coil 2 is energized, the magnetic force overcomes the spring force and lifts the moving iron core together with the valve core. Due to the special structure of the static iron core, under the control of the controller, the moving iron core and the valve core can be lifted to different positions. Degree.

Abstract

The solenoid valve with continuously adjustable spool movement has a set of electromagnetic coils with an outer iron core yoke. Sliding cylindrical moving iron core, the moving iron core is made of soft magnetic alloy material, a spool is riveted in its center, the bottom of the hollow static iron core is sealed and positioned with non-magnetic material, and the static iron core is connected by the connecting nut Connected to a hollow push-rod plastic valve body with a return spring, the hollow static iron core is a three-section combined structure, that is, it is divided into three sections along the axial direction, the two edge sections are made of soft magnetic materials, and the middle is non-magnetic. Material. According to the above-mentioned structure of the solenoid valve of the present invention, those skilled in the art can easily see that the present invention overcomes the above-mentioned defects of the existing solenoid valve, not only can continuously control the movement direction, stroke and speed of the valve core, but also has a compact structure and a small volume. Small and low cost.

Description

technical field [0001] The invention relates to a solenoid valve, such as a two-position three-way proportional solenoid valve. Specifically, it is a reluctance proportional solenoid valve with continuously adjustable stroke, direction and speed. Background technique: [0002] A solenoid valve in the prior art uses a group of DC electromagnetic coils to drive the electromagnet core, relying on a certain electrical signal to make the solenoid valve core generate magnetic force, overcome the spring pressure at one end of the moving iron core, and open the vent. After the power is cut off, the moving iron core loses its electromagnetic power, and the spring pushes the moving iron core back to its original position to close the vent. The defect of this solenoid valve is that it cannot adjust the speed of the air pressure output, and when it reaches the spring pressure, it acts instantaneously, and only plays the role of closing and opening the valve within the specified stroke....
