Description

Technical Field

[0001] This invention relates to a valve, specifically an airflow distribution valve. Background Technology

[0002] In the ventilation system ducts of equipment such as air conditioners, duct tees and airflow regulating valves are typically installed. Both duct tees and airflow regulating valves are duct components. A duct tee, with one inlet and two outlets, or two inlets and one outlet, is mainly used to change the direction of fluid flow at the confluence of three ducts, but it cannot regulate the airflow in and out of each duct. An airflow regulating valve is installed on a duct; by adjusting the valve's opening angle, the airflow through that duct is controlled, thus affecting the airflow distribution to other ducts.

[0003] Because of the functional differences between duct tees and air volume regulating valves, it is impossible to achieve both functions in one component. In practical applications, both components must be used simultaneously, which occupies duct space.

[0004] In addition, existing air valves adjust airflow by vertically changing the ventilation area, resulting in greater ventilation resistance. Summary of the Invention

When it slides to the position between the two ends of the air valve track (24), a part of the air inlet (11) is connected to the first exhaust port (12), and the other part of the air inlet (11) is connected to the second exhaust port (13), thereby realizing the function of air volume regulation and air direction switching.

[0014] Preferably, the movable valve plate (21) is made of a semi-flexible material, which adaptively forms a streamlined air duct according to the pressure of the fluids on both sides, thereby reducing the flow resistance of the fluids on both sides.

[0035] To make the technical problems solved, the technical solutions, and the beneficial effects of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the invention.

[0036] This invention provides an airflow distribution valve that integrates the functions of a duct tee and an airflow regulating valve. It is a component that combines two functions: firstly, as a tee, it changes the fluid direction, achieving fluid collection and distribution; secondly, as a regulating valve, it proportionally distributes airflow between pipes, reducing the number of pipe components. Therefore, this application combines fluid direction changing with airflow distribution functions. Furthermore, the airflow distribution valve of this invention is a flexible regulating valve. Through its special design, it can achieve a near-streamlined ventilation structure at any angle, with very low pressure loss on both sides of the outlet, thus resulting in low ventilation resistance.

[0037] The simple plug-in structure of this invention facilitates the temporary expansion of more ventilation branches on the construction site; it also makes it easier to expand multiple branches, achieving 4-way, 5-way, etc., through plug-in connections.

[0038] Furthermore, the air volume distribution valve provided by this invention not only combines the functions of fluid direction change and free air volume distribution into one device, but also finds a combination method with the least resistance through design, solving the problem of too many pipe components caused by the original combination of air duct tee and air volume regulating valve, thereby achieving the effect of one valve realizing two functions.

[0039] The air volume distribution valve provided by this invention is referenced. Figure 1 and Figure 2 It includes: valve body 10 and valve assembly 20;

[0040] The valve housing 10 is equipped with an air inlet 11, a first air outlet 12, and a second air outlet 13 that are interconnected; a valve assembly 20 is installed in the inner cavity of the valve housing 10; the valve assembly 20 is rotatable, thereby adjusting the air duct state from the air inlet 11 to the first air outlet 12, and the air duct state from the air inlet 11 to the second air outlet 13.

[0041] The first air outlet 12 and the air inlet 11 are connected in a straight line to form a horizontal air duct;

[0042] The second air outlet 13 is perpendicular to the horizontal air duct, and the second air outlet 13 and the air inlet 11 are connected in an arc shape to form an arc-shaped air duct.

[0043] Therefore, the air volume distribution valve provided by the present invention has the functions of both a duct tee and an air volume regulating valve.

[0044] As a specific implementation example, such as Figure 3 As shown, the valve assembly 20 includes a movable valve plate 21, a valve shaft 22, and a fixed valve plate 23;

[0045] The valve shaft 22 is vertically disposed within the inner cavity of the valve housing 10; a movable valve plate 21 is mounted on the left side of the valve shaft 22, and a fixed valve plate 23 is mounted on the right side of the valve shaft 22; the right side of the fixed valve plate 23 is fixed to the housing wall between the first exhaust port 12 and the second exhaust port 13, from... Figure 3 As can be seen, bolts are installed on the upper and lower right sides of the fixed valve plate 23 to fix the right side of the fixed valve plate 23 to the housing wall; the left side of the movable valve plate 21 is connected to the air valve track 24 inside the air inlet 11; from Figure 3 As can be seen, the left side of the movable valve plate 21 has a sliding column embedded in the air valve track, thereby enabling the movable valve plate 21 to slide.

[0046] Its usage is as follows: When the valve shaft 22 rotates, it drives the movable valve plate 21 to slide along the air valve track 24. When it slides to the outer end of the air valve track 24, the air duct from the air inlet 11 to the second air outlet 13 is fully opened, and the air duct from the air inlet 11 to the first air outlet 12 is fully closed. When it slides to the inner end of the air valve track 24, the air duct from the air inlet 11 to the second air outlet 13 is fully closed, and the air duct from the air inlet 11 to the first air outlet 12 is fully opened. When it slides to the position between the two ends of the air valve track 24, a part of the air inlet 11 is connected to the first air outlet 12, and the other part of the air inlet 11 is connected to the second air outlet 13, thereby realizing the function of air volume regulation and air direction switching.

[0047] In addition, in this invention, such as Figure 10 As shown, the movable valve plate 21 is made of a semi-flexible material, such as a thin metal plate or a bendable plastic plate. Therefore, it can adaptively form a streamlined air duct according to the pressure of the fluids on both sides, thereby reducing the flow resistance of the fluids on both sides.

[0048] As a specific implementation example, the valve shaft 22, the movable valve plate 21, and the fixed valve plate 23 are assembled in the following manner:

[0049] like Figure 4 and Figure 5 As shown, the valve shaft 22 has a movable valve plate groove 22-1, as... Figure 6 The diagram shows the structure of the movable valve plate 21. The right side of the movable valve plate 21 is inserted into the movable valve plate groove 22-1 and fixed with bolts. After the movable valve plate 21 and valve shaft 22 are assembled, the fixed valve plate 23 is assembled. As shown in the diagram, the fixed valve plate 23 has a fixed bushing 23-1 at its left end, which is fitted around the valve shaft 22. Therefore, when the valve shaft 22 rotates, it drives the movable valve plate 21 to rotate simultaneously, but the fixed valve plate 23 remains stationary. In traditional solutions, the air volume valve is limited by its valve structure and the material of the valve plate, resulting in high resistance. No air volume distribution valve can effectively reduce its resistance while achieving the functions of changing the fluid direction and freely distributing the air volume. Specifically, because the resistance of existing air volume distribution valves depends on the valve structure and the material of the valve plate, in order to facilitate the adjustment and distribution of air volume, the material of the valve plate is generally selected to have high rigidity or a structure that is not easily deformed. This results in the inability to form a smooth air duct when the air volume of one of the air passages is zero in a three-way air volume distribution valve. Therefore, valve plates made of this material or structure will generate great resistance, reduce wind speed, and ultimately lead to increased energy consumption of the fan or failure to reach the designed wind speed.

[0050] The movable valve plate provided in this application has a certain degree of toughness. When the air volume of a certain air outlet is adjusted to zero, a smooth air duct can be formed, reducing resistance.

[0051] In addition, for ease of operation and to achieve positioning after the movable valve plate 21 slides into place, the valve assembly 20 also includes an angle fixing unit; see reference. Figure 3 An angle fixing unit is installed on the top of the valve body 10 and includes: a turntable 25, a fastening screw 26 and a fastening knob 27;

[0052] The turntable 25 is fixed to the top of the valve shaft 22; the turntable 25 has a sliding groove 28; a fastening screw 26 is disposed in the sliding groove 28 and fixed to the valve body 10; the fastening screw 26 is fitted with a fastening knob 27. It also includes an operating handle 29; the operating handle 29 is fixed to the turntable 25. Therefore, the operating handle 29 drives the turntable 25 to rotate, and when the turntable 25 rotates, it drives the valve shaft 22 to rotate synchronously; when it reaches the desired position, tightening the fastening knob 27 will lock it in place.

[0053] The specific process is as follows: the operating handle 29 controls the valve shaft 22, which drives the movable valve plate 21 to rotate, thereby adjusting the distributed air volume. The rotation angle is fixed by the fastening knob 27. The flowing air enters from the air inlet 11, is split by the movable valve plate 21, and then flows out from the two exhaust ports.

[0054] To enable insertion when two adjacent valves are very close together, the airflow distribution valve provided by this invention also includes the following structure:

[0055] An air inlet flange 14 is fitted to the outside of the air inlet 11; a first exhaust flange 15 is fitted to the outside of the first exhaust outlet 12; the outer periphery of the first exhaust flange 15 has a first flange clip 16; a second exhaust flange 17 is fitted to the outside of the second exhaust outlet 13; the outer periphery of the second exhaust flange 17 has a second flange clip 18. The air inlet flange 14 and the first exhaust flange 15 have the same shape and size. The flanges are the same size and have a male-female joint structure, allowing for insertion.

[0056] Therefore, for two adjacent airflow distribution valves, such as Figure 9 As shown, the first exhaust flange 15 of the first exhaust port 12 of the first air volume distribution valve is aligned with the air inlet flange 14 of the air inlet 11 of the second air volume distribution valve, and the two flanges are fixed by the first flange buckle 16; and so on, to realize the plug-in connection of multiple air volume distribution valves.

[0057] In addition, the first exhaust port 12 and the second exhaust port 13 of each air volume distribution valve can be directly connected to the pipeline, making assembly convenient.

[0058] Therefore, the air volume distribution valve of the present invention can be connected to pipes at both exhaust ports, or it can be directly connected to the same air volume distribution valve.

[0059] Installation process: During installation, insert the valve socket into the inlet of another valve or pipe, fasten the flange clips, and the valve will be fixed in place. The installation is then complete.

[0060] Traditional airflow distribution valves are complex to install. For example, a short pipe needs to be added between the two valve flanges for easy disassembly and maintenance, which takes up a lot of space, makes the connection complicated, and is not suitable when the two valves are close to each other.

[0061] The air volume distribution valve of this application adopts a flange snap-fit ​​connection method, which has the advantages of simple and convenient installation, disassembly and maintenance.

[0062] The airflow distribution valve provided by this invention reduces air resistance at any airflow rate while simultaneously changing the flow direction and freely distributing airflow. Furthermore, its simple structure minimizes space requirements and allows for plug-in connection even when adjacent valves are very close together, broadening its applicability. The simple plug-in structure facilitates the temporary expansion of more ventilation branches on-site; it also makes it easier to expand into multiple routes, achieving 4-way, 5-way, etc., through plug-in connections.

[0063] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
