Description

Technical Field

[0001] The utility model relates to the field of electromagnetic valves, in particular to a electromagnetic valve with double coils. Background Art

[0002] As a key component in fluid control systems, solenoid valves are widely used in various industrial automation, mechanical equipment and daily life. Their performance directly affects the operating efficiency and reliability of the entire system.

[0003] In the prior art, traditional dual-coil solenoid valves typically use a method whereby a single coil is energized separately to drive the solenoid valve to complete switching or other predetermined actions. While this design meets basic application requirements to a certain extent, in certain demanding applications, the solenoid valve is required to provide a greater electromagnetic force to overcome greater resistance or achieve a faster response speed. However, simply increasing the number of turns and resistance of a single coil to increase the electromagnetic force is often affected by the system voltage control and power limitations, making it difficult to achieve the desired effect. At the same time, in harsh environments or scenarios where maintenance is difficult, once the solenoid valve coil fails, the entire system may be paralyzed, and there is a lack of effective emergency measures to ensure the continued operation of the system.

[0004] Therefore, existing dual-coil solenoid valves have significant deficiencies in functional flexibility, electromagnetic force output, emergency backup, and environmental adaptability, making it difficult to meet the growing market demand for high-performance, high-reliability solenoid valves. Therefore, developing a new dual-coil solenoid valve that can both operate independently and simultaneously increase electromagnetic force output, while also providing emergency backup functionality, is a pressing issue for those skilled in the art. Utility Model Content

[0005] Based on the above problems existing in the prior art, the present invention aims to provide a solenoid valve with a double coil, so as to improve the electromagnetic force output of the existing solenoid valve and enhance the stability of use.

[0006] In order to achieve the above purpose, the technical solution of the utility model is to design a solenoid valve with double coils, including a shell and a solenoid valve, the solenoid valve is arranged in the shell, and the front and rear ends of the solenoid valve are respectively provided with a first coil and a second coil.

[0007] Furthermore, the first coil positive wire and the first coil negative wire are connected to the rear portion of the first coil, and the second coil positive wire and the second coil negative wire are connected to the front portion of the second coil.

[0008] Furthermore, a wiring hole is opened on the upper part of the shell, and the positive wire of the first coil, the negative wire of the first coil, the positive wire of the second coil and the negative wire of the second coil extend from the wiring hole.

[0009] Furthermore, the first coil positive wire, the first coil negative wire, the second coil positive wire and the second coil negative wire are respectively provided with different colors for easy distinction during wiring.

[0010] Furthermore, the positive and negative poles of the first coil and the second coil have the same winding direction. If they are different, the electromagnetic fields of the two coils will cancel each other out and no electromagnetic force will be output when the electromagnetic fields are passed through the two coils at the same time.

[0011] Preferably, the first coil and the second coil are connected in parallel.

[0012] Preferably, the first coil and the second coil are connected in series.

[0013] Furthermore, an armature is provided in the middle of the solenoid valve, and a push rod and a valve core are provided at the rear of the armature.

[0014] Advantages and beneficial effects of the present invention: The present invention allows the first coil and the second coil to be energized separately or simultaneously by designing a dual-coil structure, so that the solenoid valve can superimpose electromagnetic force when needed, thereby overcoming the high electromagnetic force requirements that traditional solenoid valves cannot achieve due to voltage control and power limitations. This design is particularly suitable for application scenarios that require large electromagnetic force output, and improves the applicability and performance of the solenoid valve. The dual-coil design not only improves the electromagnetic force output of the solenoid valve, but also provides it with an emergency backup function. In harsh environments or scenarios where maintenance is difficult, if one of the coils fails, the other coil can still work normally, ensuring the continuous operation of the solenoid valve and the entire system, greatly improving the stability of use. The solenoid valve supports the parallel and series use of coils, so that the solenoid valve can flexibly adjust the electromagnetic force output according to the needs of specific application scenarios. This flexibility enables the solenoid valve to better adapt to different working environments and control systems, and meet diverse application needs. BRIEF DESCRIPTION OF THE DRAWINGS

In addition, it should be understood that the specific implementation methods described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0020] like Figure 1 As shown, the utility model is mainly composed of a shell 1 and a solenoid valve body 2 , and the solenoid valve body 2 is fixedly installed in the inner space of the shell 1 .

[0021] The front section of the solenoid valve body 2 is tightly fitted with a first coil 3, while the rear section houses a second coil 4. Both coils are used to generate an electromagnetic field to actuate the solenoid valve. In this embodiment, an orange positive wire 31 and a brown negative wire 32 extend from the rear of the first coil 3. A white positive wire 41 and a black negative wire 42 extend from the front of the second coil 4. The four coil wires are each colored to facilitate easy identification and avoid wiring errors.

[0022] The upper portion of the housing 1 is provided with a wiring hole 11 for passing through the positive and negative wires of the four coils, so as to facilitate connection with an external power supply or control system.

[0023] To ensure that the first coil 3 and the second coil 4 can generate enhanced electromagnetic force when energized at the same time, the winding directions of the positive and negative coils of the two are designed to be the same to avoid mutual cancellation of the magnetic fields.

[0024] The first coil 3 and the second coil 4 can be connected in parallel or in series according to actual needs:

[0025] In the first embodiment, the first coil 3 and the second coil 4 are connected in parallel to achieve superimposed output of electromagnetic force.

[0026] In the second embodiment, the first coil 3 and the second coil 4 are connected in series, which is suitable for specific electromagnetic force requirements or system voltage and power limitations.

[0027] Figure 2 1 is a comparison of the electromagnetic forces of the double coils in different energized states in the first embodiment and the second embodiment.

[0028] The solenoid valve body 2 is located in the middle of the armature 2, which is the direct target of the electromagnetic force. The rear of the armature 21 is connected in sequence to a push rod 22 and a valve core 23. When the electromagnetic force acts on the armature 21, the push rod 22 transmits power, driving the valve core 23 to complete the opening and closing operation.

[0029] Specific steps:

[0030] The solenoid valve of this utility model exhibits high flexibility and reliability. When a larger electromagnetic force output is required, the first coil 3 and the second coil 4 can be connected in parallel. In this way, the two coils will be energized at the same time, generating a superimposed electromagnetic force, thus meeting the application scenario with high electromagnetic force requirements.

[0031] Under system voltage control and power limitations, the electromagnetic force output can be flexibly adjusted to suit specific application requirements by selecting parallel or series connections for the coils. This flexible usage enables the solenoid valve of this utility model to be widely used in various industrial automation, mechanical equipment, and daily life, meeting the demand for high performance and high reliability of solenoid valves in different fields.

[0032] At the same time, when faced with maintenance difficulties or when emergency backup is needed, even if one of the coils fails, the other coil can still work independently to ensure the normal operation of the solenoid valve, greatly improving the stability and reliability of the system.

[0033] The above describes in detail the dual-coil solenoid valve provided by the present invention. This article uses specific examples to illustrate the principles and implementation methods of the present invention. The description of the above examples is intended only to facilitate understanding of the method and core concept of the present invention. It should be noted that those skilled in the art may make various improvements and modifications to the present invention without departing from the principles of the present invention, and such improvements and modifications fall within the scope of protection of the claims of the present invention.
