Description

Technical Field

[0001] The utility model belongs to the field of electromagnetic valves, in particular to a high-frequency electromagnetic valve. Background Art

[0002] Spraying fluids such as hot melt adhesive, polyurethane adhesive, and epoxy resin requires the use of a spray valve to ensure even and precise application of the glue to the desired surface. The viscosity and properties of these fluids require high-performance spray equipment. A significant portion of existing spray valves are pneumatic valves, which are driven by air pressure, typically using compressed air as a power source. These valves rely on changes in air pressure to open and close the valve, thereby controlling the glue's dispensing and flow rate.

[0003] However, to achieve stable fluid spraying, especially in high-precision and high-frequency applications, relying solely on pneumatic valve air source regulation is insufficient. Stable air source control not only affects spraying results but also directly impacts production efficiency and product quality. Therefore, stable control of the pneumatic valve air source is essential to ensure the desired spraying results every time.

[0004] As a common and effective air source control device, solenoid valves offer the advantages of fast response and high control precision, making them widely used in many fields. Their application to pneumatic valves can significantly improve the overall performance of spray systems. However, designing a solenoid valve structure that effectively controls the air source of pneumatic valves is a pressing technical challenge in the existing technology. Utility Model Content

[0048] In this embodiment, the control module 1 sends a high-frequency pulse signal to the electromagnetic coil assembly 2, and the electromagnetic coil assembly 2 is energized to generate magnetic attraction to control the movable push rod 32 to move up and down. When it moves to the upper side, the cylinder air inlet 311 and the second air outlet 313 are blocked, and the air source is discharged from the first air outlet 312; when it moves to the lower side, the cylinder air inlet 311 and the first air outlet 312 are blocked, and the air source is discharged from the second air outlet 313, thereby realizing the switching of the air source back and forth between the first air outlet 312 and the second air outlet 313, and realizing stable control of the air source; at the same time, the cylinder air inlet 311 is set on the opposite side of the first air outlet 312 and the second air outlet 313, and is located between the two, which can shorten the movable stroke of the movable push rod 32.

One end of the elastic member 4 is elastically connected to the movable push rod 32, and the other end is elastically connected to the electromagnetic coil assembly 2. In this embodiment, if only the electromagnetic coil assembly 2 is used to control the up and down movement of the movable push rod 32, an AC pulse signal is required to switch the direction of the magnetic force generated by the electromagnetic coil assembly 2, thereby achieving the upward suction or downward push of the movable push rod 32. In this embodiment, an elastic member 4 is provided. The elastic member 4 stabilizes the movable push rod 32 at one of the upper and lower ends of the cylinder body 31 through its own elastic force.
