Description

TECHNICAL FIELD

[0001] The utility model relates to air conditioning, air humidification, ventilation, the technical field of the application of air flow as shielding, especially relates to a one-way valve suitable for multiple installation angles. BACKGROUND

[0002] With the rapid development of mobile communication, the number of base stations is increasing, which makes the operator's energy consumption demand increasing. From the operation and maintenance point of view, energy saving cannot meet the demand. Only from the main equipment and air conditioner of the machine room can the power consumption of the base station be actually reduced and the operation cost be saved. At present, the energy consumption is generally reduced by air conditioning equipment.

[0003] The air conditioning equipment obtains the temperature and humidity data in the current machine room, and sends cold air into the machine room after reaching the starting value. The heat exchange between the cold air and the heat generated by the equipment in the machine room, and the heat exchange after the heat exchange is discharged from the machine room through the exhaust unit, and the temperature and humidity control in the machine room is completed.

[0004] Because the existing air conditioning equipment is widely used in various machine rooms, including satellite mobile communication stations, medical equipment rooms, laboratories, test rooms, precision electronic instrument production workshops and other high-precision environments, in order to ensure its applicability, the air conditioning equipment needs to be modified to some extent, at least to match the air supply channel and return air channel with the space to be controlled. This matching is embodied in the setting of the air outlet and return air outlet.

[0005] In the prior art, the one-way air valve at the one-way ventilation of the air conditioning equipment is generally made of aluminum alloy structure, which has the problem of inconvenient installation. The inlet and outlet directions of the one-way air valve need to be clearly defined to prevent the air supply and return air from being mixed due to reverse direction. More importantly, in order to meet the design requirements, the existing air conditioning equipment often appears in the form of a main machine and multiple standby machines, which requires the installation of a one-way air valve and the realization of horizontal air supply. This leads to the fact that once the air valve is installed incorrectly or the angle deviation is large, the cold air will directly converge with the hot air without passing through the cabinet, resulting in the situation of "cold short circuit", and thus the technical requirements of the shortest air supply path and the smallest cold loss cannot be met.

[0025] The present invention will be further described in detail below with reference to the embodiments, but the protection scope of the present invention is not limited thereto.

[0026] The utility model relates to an air-conditioning one-way valve suitable for multiple installation angles, comprising a valve seat 1, a plurality of parallel flexible valve leaves 2 cooperating with the valve seat 1, and a limit assembly cooperating with the flexible valve leaves 2.

[0027] In the present invention, the valve seat 1 is retained as the installation body of the air-conditioning one-way valve, and it will be installed at the air inlet of the corresponding air-conditioning air inlet channel or the air outlet of the air-conditioning air supply channel, but there is no longer a restriction on the installation direction of the valve seat 1. It can be installed horizontally based on needs, or vertically based on needs, or tilted at a certain angle, as long as it meets the design requirements.

[0028] In the present invention, the flexible valve leaf 2 generally adopts a fireproof cloth structure, which has a fireproof and flame-retardant coating and has a certain thickness and strength. It is arranged on the same surface of the valve seat 1 so that it can be blown open when air is out or in, thereby achieving the purpose of one-way conduction.

[0029] In the present invention, in order to meet the requirements of one-way conduction and good reset performance of the air-conditioning one-way valve, a limit assembly is provided in conjunction with the flexible valve leaf 2. Obviously, the limit assembly is used to limit the flexible valve leaf 2 on the valve seat 1.

[0030] Any of the flexible valve leaves 2 includes a fixed end 21 and an air outlet end 22 ; the limiting assembly includes a positioning rod 3 that cooperates with the fixed end 21 to be fixed on both sides of the valve seat 1 .

[0031] In the present invention, it should be noted that the flexible valve leaf 2 is generally a long rectangular strip, and the fixed end 21 and the air outlet end 22 are the ends corresponding to the two long sides. The two sides of the long side corresponding to the fixed end 21 are fixed to the two sides of the valve seat 1, and the two short sides are the sides that can be flipped up by the action of wind.

[0032] In the present invention, the fixed end 21 needs to be fixed to both sides of the valve seat 1 , so a positioning rod 3 is used to match the flexible valve leaf 2 and the valve seat 1 . There are at least two implementation methods.

[0033] The positioning rod 3 is uniformly provided with a plurality of connecting pieces 4 between the positioning rod 3 and the fixed end 21, and both ends of the positioning rod 3 are fixed to the two sides of the valve seat 1.

[0034] In the embodiment, the connecting piece 4 connects the positioning rod 3 and the fixed end 21 for each flexible valve leaf 2, that is, the positioning rod 3 and the flexible valve leaf 2 are connected at the long edge, and both ends of the positioning rod 3 are fixed to the valve seat 1.

[0035] In the embodiment, the connecting piece 4 connects the positioning rod 3 and the fixed end 21 for each flexible valve leaf 2, that is, the positioning rod 3 and the flexible valve leaf 2 are connected at the long edge, and both ends of the positioning rod 3 are fixed to the valve seat 1.

[0036] In the embodiment, the connecting piece 4 connects the positioning rod 3 and the fixed end 21 for each flexible valve leaf 2, that is, the positioning rod 3 and the flexible valve leaf 2 are connected at the long edge, and both ends of the positioning rod 3 are fixed to the valve seat 1.

[0037] It should be noted that in the embodiment, the positioning rod 3 and the first tunnel still need to be fixed in position as needed to prevent relative sliding of the two; the embodiment 2 is different from the embodiment 1 in that the positioning rod 3 is not exposed except for the two ends.

[0038] The positioning rod 3 is a metal rod, and the limiting assembly further comprises a magnetic body 5 arranged at a corresponding position of the next flexible valve leaf 2 in cooperation with the positioning rod 3 of the previous flexible valve leaf 2.

[0039] The magnetic body 5 is one or more and is uniformly arranged on the corresponding flexible valve leaf 2.

[0040] In the utility model, the positioning rod 3 is arranged as a metal rod, the material thereof can be selected by the person skilled in the art as required, and it needs to be adsorbed by the magnetic body 5; specifically, the air outlet end 22 of the next flexible valve leaf 2 or the vicinity thereof is provided with the magnetic body 5, and the positioning rod 3 of the fixed end 21 of the previous flexible valve leaf 2 is a metal rod, that is, the two are closed in a static state and are opened when wind acts.

[0041] In specific implementation, in order to avoid work confusion of the flexible valve leaf 2, the magnetic body 5 is uniformly arranged on the next flexible valve leaf 2 corresponding to the positioning rod 3 of the previous flexible valve leaf 2, and is generally multiple.

[0042] The air outlet end 22 of any of the flexible valve leaves 2 is provided with a reset assembly.

[0043] The reset assembly comprises an elastic piece 7 penetrating a second tunnel 6 of the air outlet end 22 of any of the flexible valve leaves 2, and both ends of the elastic piece 7 are fixed to the corresponding side of the valve seat 1.

[0044] In the present invention, considering the application of the flexible valve leaf 2, it is necessary to ensure that it can return to its original position after the air flow ends to avoid air leakage, so a reset component is configured; specifically, a second tunnel 6 is set at the air outlet end 22 of the flexible valve leaf 2, and an elastic member 7 is passed through the tunnel and the two ends of the elastic member 7 are fixed to the valve seat 1, so that after the air flow ends, the air outlet end 22 of the flexible valve leaf 2 can always return to the initial position under the action of the elastic member 7 and close the air duct through the magnetic body 5 and the metal positioning rod 3; in actual applications, the elastic member 7 includes but is not limited to rubber bands, etc.

[0045] Adjacent flexible valve leaves 2 partially overlap.

[0046] The next flexible valve leaf 2 covers 1 / 8 to 1 / 4 of the fixed end 21 side of the previous flexible valve leaf 2 .

[0047] In the present invention, in order to ensure the closure of the air duct in the initial state, the two flexible valve leaves partially overlap in the initial state. However, in order to save energy and consider the efficiency of the one-way valve, it is necessary to obtain the optimal coverage ratio through multiple tests.

[0048] In the present invention, according to multiple tests, the optimal width of the blade is 60 mm, and the overlapping part of the blade is 10 mm, which satisfies the requirement that the next flexible valve leaf 2 covers 1 / 6 of the fixed end 21 side of the previous flexible valve leaf 2, which can not only ensure that the air duct is well closed, but also make the air duct ventilation efficiency high.

[0049] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
