Description

Technical Field

[0001] This utility model relates to the technical field of duct connection accessories, specifically a new type of duct elbow. Background Technology

[0002] Traditional duct elbows mostly guide airflow directly through the inner wall. Although the structure is simple, it is difficult to adapt to the use requirements of fresh air units that have both condensation and heat preservation functions in terms of some functions. Moreover, once the duct is laid on the ground, it is difficult to replace it later. Therefore, it is particularly important to improve the functional effect of duct elbows. Based on this, the inventor researched and proposed this solution. Utility Model Content

[0003] This invention provides a novel duct elbow that overcomes the shortcomings described in the background art.

[0004] The technical solution adopted by this utility model to solve its technical problem is:

[0005] A new type of air duct elbow includes an elbow body, an extension pipe opening, and a guide plate. The elbow body has open openings on both sides, and an extension pipe opening is provided at the open opening. The elbow body and the extension pipe opening are arranged in layers, and a plurality of guide plates are provided inside the extension pipe opening.

[0006] In some embodiments, the extension port includes a first extension port and a second extension port, wherein the first extension port and the second extension port have different orientations.

[0007] In some embodiments, the guide plate is installed on the inner wall of the first extension port and the second extension port, and the structural orientation of the guide plate is consistent with the orientation of the first extension port and the second extension port. That is, the guide plate does not guide the flow in a straight line, but can guide the flow in an arc along the structural orientation of the guide plate.

[0008] In some embodiments, a partition plate is provided between the outer wall of the extension pipe and the inner wall of the elbow body, and a hollow space is formed.

[0009] In some embodiments, the elbow body, extension pipe, and guide plate are made of PVC.

[0010] In some embodiments, the hollow space is filled with thermal insulation material.

[0011] In some embodiments, the insulation material is polyurethane.

[0012] In some embodiments, the insulation material is a solvent spray.

[0013] In some embodiments, the thickness of the deflector is greater than the thickness of the spacer.

[0014] In some embodiments, a notch is pre-fabricated on the extension pipe opening. The PVC extension pipe opening has a certain degree of elasticity. When the fresh air duct elbow is used to connect to the straight pipe, the notch can provide a certain deformation space, which facilitates the efficient connection of the fresh air duct elbow to the straight pipe.

[0015] By adopting the above technical solution, the beneficial effects of this utility model are:

[0016] 1. This utility model improves the stability and sealing effect of the connection between the elbow body and other pipelines by setting a first extension port and a second extension port.

[0017] 2. This utility model has several guide plates inside the extension pipe opening, and the guide plates can efficiently guide the flow along their structural direction.

[0018] 3. This utility model sets a partition plate between the outer wall of the extension pipe and the inner wall of the elbow body, forming a hollow space. By filling the hollow space with insulation material, the insulation effect of the duct head is improved, which can efficiently meet the needs of fresh air units with condensation and insulation functions.

[0027] like Figures 1-5As shown, this utility model provides a fresh air duct elbow, including an elbow body 1, an extension pipe port 2, and a guide plate 3. The elbow body 1 has open openings 4 on both sides, and an extension pipe port 2 is provided at the open opening 4. The elbow body 1 and the extension pipe port 2 are arranged in layers, and a plurality of guide plates 3 are provided inside the extension pipe port 2.

[0037] Example 1

[0038] like Figures 1-4As shown, this embodiment provides a fresh air duct elbow, including an elbow body 1, an extension port 2, and a guide plate 3.
