Description

Technical Field

[0001] The utility model belongs to the technical field of valves and relates to an automatic dust extraction control valve. Background Art

[0002] Dust extraction systems play a vital role in numerous industrial production and environmental management applications. Automatic dust extraction control valves are key components, enabling precise control of the dust extraction process.

[0003] However, existing automatic dust extraction control valves have significant shortcomings. For one thing, they lack multi-pipe switching capabilities. In practical applications, efficient dust extraction often requires flexible switching between multiple dust extraction pipes based on different work areas and equipment operating conditions. However, existing valves struggle to meet this requirement, limiting the flexibility and adaptability of dust extraction systems.

[0004] On the other hand, existing valves of this type are extremely difficult to maintain. Their internal structures can be complex and illogical, requiring significant time and effort for routine inspections, repairs, and component replacements. These maintenance difficulties can even impact the normal operation of the dust extraction system, increasing overall operating costs and the risk of downtime.

[0005] Therefore, it is necessary to improve the existing technology to overcome the defects in the existing technology. Utility Model Content

[0029] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0030] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0031] In the present invention, unless otherwise specified, directional words such as "up, down, top, bottom" are usually used with reference to the directions shown in the drawings, or with reference to the components themselves in the vertical, perpendicular or gravity direction; similarly, for ease of understanding and description, "inside and outside" refer to the inside and outside relative to the outline of each component itself, but the above directional words are not used to limit the present invention. Example

[0032] See also Figures 1-4 As shown, an automatic dust extraction control valve is designed to solve the problem that existing dust extraction valves cannot achieve multi-pipeline switching and are inconvenient to maintain.

[0033] The automatic dust extraction control valve includes a valve housing 1, which contains a chamber 11. Valve housing 1 is equipped with at least two air inlets 12 and one air outlet 13, both of which are connected to chamber 11. Valve housing 1 is also equipped with air inlet pipes 2 and 7 connected to air inlets 12, and an air outlet pipe 3 connected to air outlet 13.

[0034] Valve 5 is installed within chamber 11 to seal air inlet 12. Each air inlet has a separate valve 5 for sealing. Each valve 5 is connected to an independent cylinder 4 located within valve chamber 1. This unique design allows individual cylinders 4 to precisely control the closing and opening of valves 5 within the valve chamber, effectively switching different pipelines on and off.

[0035] Furthermore, a sealing gasket 6 is provided on the side of the valve 5 near the air inlet 12. The sealing gasket 6 can tightly cover the outer contour of the corresponding air inlet, forming a good sealing effect, effectively preventing gas from leaking from the gap between the air inlet and the valve during the dust extraction process, further improving the sealing performance of the valve and the dust extraction efficiency.

[0036] In this embodiment, the valve chamber 1 adopts a rectangular parallelepiped structure. This regular shape facilitates installation and layout. It is equipped with two air inlets 12, both located on one side of the valve chamber 1, creating a regular layout. On the opposite side, two cylinders 4 are located. This arrangement facilitates the coordinated operation of various components without interfering with each other.

[0037] The air inlet pipe 7 connected to one of the air inlets has only one dust extraction port 71, which is connected to one dust extraction device. The air inlet pipe 2 connected to the other air inlet is equipped with three dust extraction ports 21, 22, and 23, which can be connected to three dust extraction devices when in use, meeting the dust extraction needs of multiple devices. If one of the three dust extraction ports is not needed temporarily, it can be easily blocked with a head. In addition, the number of dust extraction ports on the air inlet pipe 2 is not fixed to three, and can be flexibly determined according to the actual application scenario to meet the diverse dust extraction operation requirements.

[0038] Furthermore, the ends of the air inlet pipes 2 and 7 are equipped with flanges that are bolted to the valve chamber 1. This not only ensures the secure connection between the air inlet pipes 2 and 7 and the valve chamber 1, ensuring proper dust extraction, but also greatly enhances the ease of assembly and disassembly of the air inlet pipes 2 and 7. If actual usage requirements change, such as an air inlet pipe failure or the need to replace an air inlet pipe of a different specification, the air inlet pipe can be quickly replaced based on the specific situation, effectively increasing the overall flexibility of the device.

[0039] The upper end surface of the valve cavity 1 of the automatic dust extraction control valve is provided with a detachable cover plate 14, which is tightly locked with the valve cavity 1 by bolts. This detachable design provides great convenience for inspection and maintenance of the valve cavity, and the staff can easily remove the cover plate to carry out related operations.

[0040] It is worth mentioning that the cover plate 14 is provided with an upward boss, and the air outlet 13 is arranged on the boss. Through the layout, the space is reasonably utilized, the air outlet 13 is ensured to be in a relatively appropriate position during work, the dust extraction gas is smoothly discharged, and the functionality and practicability of the dust extraction automatic control valve are further improved.

[0041] The dust extraction automatic control valve has many advantages, which has fast switching speed, can quickly respond to different dust extraction pipeline switching requirements, has small wear in the frequent switching process, and can effectively prolong the service life. Meanwhile, the overall structure is simple, and the dust extraction automatic control valve is convenient to install, maintain and overhaul, and greatly improves the defects of the previous dust extraction valve.
