Description

Technical Field

[0001] The utility model relates to the technical field of four-way valves, in particular to a four-way valve. Background Art

[0002] A four-way valve refers to a valve body with four ports, including the inlet. In addition to the common four-way valve used to control fluids, there are also four-way valves used to control material classification, which discharge materials by classification through the three discharge ports.

[0003] At present, when using a four-way valve for classifying and discharging materials, it is necessary to adjust the direction of the inner cylinder discharge and align it with any one of the three discharge ports so that the material can be discharged from the discharge port. However, in actual operation, it is found that each time the inner cylinder discharge direction is adjusted, it is easy to deviate or become unstable after adjustment, resulting in the material being discharged from one or more discharge ports at the same time during discharge, causing classification confusion. Therefore, it is necessary to design a four-way valve that can prevent deviation and is stable after adjustment to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0020] The following diagrams illustrate various embodiments of the present invention. For clarity, many physical details will be included in the following description. However, it should be understood that these physical details are not intended to limit the present invention. In other words, in some embodiments of the present invention, these physical details are not essential. Furthermore, to simplify the illustrations, some commonly used structures and components are depicted in a simplified schematic manner.

[0021] Furthermore, terms such as "horizontal," "vertical," and "overhanging" do not necessarily imply that a component must be absolutely horizontal or overhanging, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but rather that it can be slightly tilted.

[0022] In the description of this technology, it should also be noted that, unless otherwise specified or limited, the terms "disposed," "installed," "connected," and "connected" should be understood broadly. For example, they can refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this technology based on the specific circumstances.

[0023] In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the fact that ordinary technicians in this field can implement them. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by this utility model.

The centers of the two fixed disks 023 are connected to a rotating shaft 024 through bearings. The inner box body 021 is rotatably connected to the rotating shaft 024. Inside the outer box body 01, an adjustment component is provided on the front side of the outer box body 01 near the bottom end, and the adjustment component includes a limit slide 03, a limit adjustment plate 031 and a limit plug rod 035; a positioning component is provided on the front side of the outer box body 01 near the limit slide 03, and the positioning component includes a first limit socket 04, a second limit socket 041 and a third limit socket 042. The top and bottom ends of the inner box body 021 are both open, and the top opening is located on the outside of the first material guide plate 02.

[0025] See also Figure 1 and Figure 2 In this embodiment, in order to facilitate the adjustment of the position of the outlet of the inner box 021, the adjustment assembly further includes a grip 032, a first limit plate 033 and a second limit plate 034. The grip 032 is fixedly connected to the front of the limit adjustment plate 031 near the bottom end, and the end of the grip 032 away from the limit adjustment plate 031 is fixedly connected to a grip ball.

[0026] The first limiting plate 033 is fixedly connected to the outer surface of the handle 032, and the second limiting plate 034 is fixedly connected to the outer surface of the limiting plug 035. The diameters of the first limiting plate 033 and the second limiting plate 034 are both larger than the diameters of the handle 032 and the limiting plug 035;

[0027] The limiting slide groove 03 is arc-shaped and runs through the front of the outer box body 01 near the bottom. The limiting adjustment plate 031 is L-shaped and one end passes through the limiting slide groove 03 and is fixedly connected to the outer surface of the inner box body 021.

[0028] The limiting rod 035 is fixedly connected to the back of the limiting adjustment plate 031 near the bottom end, and the first limiting hole 04 is opened at the center of the front of the outer box 01 near the lower outer edge of the limiting slot 03;

At this time, grab the handle 032 to drive the limit adjustment plate 031 to slide left and right in the limit slide groove 03, thereby driving the inner box body 021 to swing left and right with the rotating shaft 024 as the center, so that the outlet direction below the inner box body 021 is adjusted. After the adjustment is completed, push the handle 032 again until the first limit plate 033 abuts against the front of the limit adjustment plate 031, and then insert the limit rod 035 into the corresponding second limit hole 041 or the third limit hole 042, thereby locking the adjusted direction, making it more stable after adjustment.
