Description

Technical Field

[0001] The utility model relates to the field of multi-way valves, in particular to a novel electromagnetic multi-way reversing valve. Background Art

[0002] The armature is a key component in a solenoid directional valve. Typically connected to the valve core, it supports the valve core and stem, ensuring stable movement of the valve core under the influence of electromagnetic force. The movement of the armature allows precise control of parameters such as the direction, flow rate, and velocity of the fluid in the solenoid directional valve to meet diverse process requirements.

[0003] Traditional electromagnetic reversing valves do not have a manual limit structure. When maintaining a certain flow direction for a long time, the armature needs to be continuously energized, which not only increases energy usage costs but also increases the risk of damage to the electromagnetic system. Utility Model Content

[0004] The utility model aims to provide a novel electromagnetic multi-way directional control valve which can be manually limited.

[0005] The purpose of the utility model is achieved as follows: a new electromagnetic multi-way reversing valve, comprising a valve body, a valve core placed in the valve body, and a shell placed on both sides of the valve body;

[0006] The valve body is provided with multiple groups of valve channels, and the valve core cooperates with the valve channels; the valve core is arranged throughout the valve body, and sealing plates are provided on the valve cores at both ends of the valve body, and the sealing plates are pressed by the limiting sleeve; the limiting sleeve is provided with an accommodating cavity on the side close to the sealing plate, and a spring seat is provided on the valve core in the accommodating cavity, and a return spring is provided on the spring seat; the two ends of the valve core are exposed outside the limiting sleeve;

[0007] An armature is provided in the circular channel. One end of the outer side of the circular channel is sealed by an end cover. A limiting rod is provided in the center of the end cover. An electrical conductive column is provided on one side of the limiting rod.

[0008] Preferably, one end of the limiting rod is exposed outside the end cover and is provided with a rotating handle, and the limiting rod and the end cover are rotatably connected via a thread.

[0009] Preferably, a contact plate is provided at one end of the limiting rod located in the circular channel, and a rubber pad is provided on the armature side of the contact plate.

[0010] Preferably, when the armature is in the initial position, both sides of the armature do not contact the valve core and the contact plate; when one end of the valve core is squeezed and the return spring is compressed to the minimum stroke, the other end of the valve core does not contact the armature.

[0011] Compared with the prior art, the present invention is beneficial in that:

[0012] A limit column is used, and the limit rod can be driven by external rotation. When multiple valves need to be in a certain position for a long time, the internal armature is limited by the limit rod, further ensuring that the valve core is in a fixed state and achieving continuous opening in a certain flow direction. At this time, the conduction can be turned off, which can save electricity, reduce the use of the electromagnetic system, and extend the service life. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] The following describes the implementation of the present invention through specific embodiments. People familiar with this technology can easily understand other advantages and effects of the present invention from the content disclosed in this specification.

[0016] It should be noted that in the description of the present utility model, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, or the orientations or positional relationships in which the utility model product is usually placed when in use. These are only for the convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present utility model. In addition, the terms "first", "second", "third" and the like are only used to distinguish descriptions, and cannot be understood as indicating or implying relative importance. Terms such as "horizontal", "vertical", and "overhanging" do not mean that the components are required to be absolutely horizontal or overhanging, but can be slightly tilted. For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0017] It should also be noted that, in the description of the present invention, unless otherwise expressly specified or limited, the terms "disposed," "installed," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections, direct connections, indirect connections via an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0018] like Figure 1As shown, a new electromagnetic multi-way reversing valve includes a valve body 1, a valve core 2 placed in the valve body 1, and a shell 3 placed on both sides of the valve body 1;

[0019] The valve body 1 is provided with multiple valve paths 101, and the valve core 2 cooperates with the valve paths 101. The valve core 2 is arranged throughout the valve body 1. Sealing plates 4 are provided on the valve core 2 at both ends of the valve body 1. The sealing plates 4 are compressed by the limiting sleeve 5. The limiting sleeve 5 has an accommodating cavity 501 on the side of the sealing plate 4. The valve core in the accommodating cavity 501 is provided with a spring seat 6, and the spring seat 6 is provided with a return spring 7. The two ends of the valve core 2 are exposed outside the limiting sleeve 5.

[0020] The housing 3 is provided with a circular channel 301 running through it, and an armature 8 is provided in the circular channel 301. One end of the outer side of the circular channel 301 is sealed by an end cover 9. A limit rod 10 is provided in the center of the end cover 9. An electrical connection post 11 is provided on one side of the limit rod 10. The electrical connection post is connected to the armature. After conducting electricity, the armature can move horizontally to the left and right, thereby driving the valve core to move horizontally.

[0021] like Figure 1 As shown, one end of the limit rod 10 is exposed outside the end cover 9 and is provided with a rotating handle. The limit rod 10 and the end cover 9 are connected by a threaded rotation. By rotating the limit rod, the lateral movement of the limit rod can be achieved, and the armature can be limited, and finally the position of the valve core can be controlled even when the power is off.

[0022] like Figure 1 As shown, a resistance plate 1001 is provided at one end of the limit rod 10 located in the circular channel 301, and a rubber pad is provided on the side of the resistance plate 1001 close to the armature 8. When the limit rod moves, the rubber pad can avoid hard contact between the limit rod and the armature, and prevent both from being damaged after being squeezed.

[0023] like Figure 1 As shown, when the armature 8 is in the initial position, both sides of the armature do not contact the valve core 2 and the contact plate 1001. When one end of the valve core 2 is squeezed and the return spring 7 is compressed to the minimum stroke, the other end of the valve core does not contact the armature.

[0024] The working principle of the utility model is explained as follows: when the flow direction needs to be frequently controlled, there is no need to rotate the limit rod, and the valve core is driven to move left and right through the conduction of the armature; when a certain flow direction needs to be maintained for a long time, the limit rod is rotated to support the armature and then the power is cut off; there is no need to drive the electromagnetic system for a long time, which avoids long-term use of the electromagnetic system and extends its service life.

[0025] The embodiments described above are merely descriptions of preferred embodiments of the present invention and are not intended to limit the concept and scope of the present invention. Any modifications and improvements to the technical solution of the present invention made by a person of ordinary skill in the art without departing from the design concept of the present invention shall fall within the scope of protection of the present invention. The technical content sought to be protected by the present invention is fully set forth in the claims.
