Description

Technical Field

[0001] The utility model belongs to the technical field of proportional valve bodies, in particular to a position limiting structure of a proportional valve electromagnet. Background Art

[0002] In proportional valves, the proportional solenoid, as a driving element, is an essential component. Existing proportional valves typically mate the solenoid directly with the valve body via a stopper and secure it with a large nut at the rear. This installation method allows the solenoid to be positioned within the valve body. However, if the valve is operated in an environment subject to vibration or shaking, the solenoid can rotate within the valve body, causing the connecting wire extending from the solenoid to be pulled during rotation. In severe cases, the wire may break, rendering the valve inoperable.

[0003] Therefore, a more reliable structure is needed to ensure that the proportional solenoid in the proportional valve does not rotate in the proportional valve body in a vibrating or shaking environment. Utility Model Content

[0004] In order to solve the above problems, the utility model proposes a proportional valve electromagnet limiting structure, including a proportional valve body and a proportional electromagnet arranged in the proportional valve body, a first positioning portion is provided inside the proportional valve body, and a second positioning portion is provided on the proportional electromagnet. The first positioning portion and the second positioning portion match and correspond to each other, so that after the proportional electromagnet is installed in the proportional valve body, it is limited to a fixed position in the proportional valve body.

[0005] Furthermore, the first positioning portion is a protrusion, and the second positioning portion is a recess corresponding to the protrusion.

[0006] Furthermore, the first positioning portion is a cylindrical protrusion, and the second positioning portion is an arc-shaped recess corresponding to the curvature of the surface of the cylindrical protrusion.

[0007] Furthermore, the first positioning portion is a notch, and the second positioning portion is a protrusion corresponding to the notch.

[0008] Furthermore, the second positioning portion is a cylindrical protrusion, and the first positioning portion is an arc-shaped recess corresponding to the curvature of the surface of the cylindrical protrusion.

[0009] The utility model provides corresponding first and second positioning parts inside the proportional valve body and outside the proportional electromagnet, so that the proportional electromagnet is limited in a fixed position after being installed inside the proportional valve body. When the overall proportional valve operating environment is subject to frequent vibration or shaking, the proportional solenoid valve will not rotate due to the first and second positioning parts.

It should be understood that other embodiments may also be used, and that mechanical, structural, electrical, and operational changes may be made without departing from the spirit and scope of the present disclosure. The following detailed description should not be considered restrictive, and the scope of the embodiments of the present application is limited only by the claims of the published patents. The terms used herein are only for the purpose of describing specific embodiments and are not intended to limit the present application.

[0023] Please refer to Figures 1-4 The utility model proposes a proportional valve electromagnet limiting structure, including a proportional valve body 1 and a proportional electromagnet 2 arranged in the proportional valve body. A first positioning portion 11 is provided inside the proportional valve body 1, and a second positioning portion 21 is provided on the proportional electromagnet 2. The first positioning portion 11 matches the second positioning portion 21, so that after the proportional electromagnet 2 is installed in the proportional valve body 1, it is limited to a fixed position in the proportional valve body 1.

[0024] In one embodiment, the first positioning portion 11 is a protrusion extending from the inner surface of the proportional valve body toward the center, and the second positioning portion 21 is a recess corresponding to the protrusion. More specifically, the first positioning portion 11 is a cylindrical protrusion, and the second positioning portion 21 is an arc-shaped recess corresponding to the curvature of the cylindrical protrusion. Alternatively, the first positioning portion 11 may be a protrusion of other shapes, while the second positioning portion 21 is a recess corresponding to the protrusion.

[0025] In another embodiment, the first positioning portion is a notch, and the second positioning portion is a projection corresponding to the notch. More specifically, the second positioning portion is a cylindrical projection extending outward from the outer surface of the proportional solenoid, while the first positioning portion is an arc-shaped notch corresponding to the curvature of the cylindrical projection. Similarly, the first positioning portion may be a notch of other shapes, while the second positioning portion is a projection corresponding to the notch.

[0026] By means of the above structure, corresponding first positioning parts 11 and second positioning parts 21 are provided inside the proportional valve body 1 and outside the proportional electromagnet 2, so that the proportional electromagnet 2 is limited in a fixed position after being installed inside the proportional valve body. When the environment in which the overall proportional valve is installed is subject to frequent vibration or shaking, the proportional solenoid valve will not rotate in the proportional valve body through the matching engagement of the first positioning part 11 and the second positioning part 21, thereby avoiding pulling the connecting wire of the proportional electromagnet 2 and causing damage to the connecting wire, thereby ensuring the reliability of the proportional valve.

[0027] In the present invention, unless otherwise clearly specified and limited, for example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. Unless otherwise clearly specified and limited, ordinary technicians in this field can understand the specific meanings of the above terms in the present invention according to specific circumstances.

[0028] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
