[0024] The terms "first", "second", etc. in the specification and claims of the utility model and the above-mentioned drawings are used to distinguish different objects, rather than to describe a specific order. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions. For example, a process, method, device, product or end that includes a series of steps or units is not limited to the listed steps or units, but optionally includes steps or units that are not listed, or optionally includes other steps or units inherent to these processes, methods, products or ends.

[0025] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present invention.

It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0026] The utility model discloses a specific implementation method of a cooling tower water inlet pressure relief device, please see Figure 1 The water inlet pressure relief device includes a water distribution pipe 3, a water sowing basin 1 and a water inlet cover plate 2 arranged above the water sowing basin 1.

[0027] In this embodiment, a water outlet connected to an external pipe is provided in the middle of the water inlet cover plate 2. Specifically, a water inlet flange 21 is fixedly installed on the top surface of the water inlet cover plate 2. The water inlet flange 21 can be fixed on the top surface of the water inlet cover plate 2 by bolts, and the water inlet flange 21 is connected to the water outlet.

[0028] As an improvement, the water distribution pipe 3 is provided with a water inlet and a plurality of drain ports 32, the water distribution pipe 3 is fixedly mounted on the bottom surface of the water inlet cover plate 2, and the water inlet of the water distribution pipe 3 is connected to the water outlet of the water inlet cover plate 2. Specifically, a pressure relief flange 31 is fixedly mounted on the water inlet of the water distribution pipe 3, the pressure relief flange 31 can be fixed on the water distribution pipe 3 by welding, and the pressure relief flange 31 can be assembled and installed with the water inlet flange 21 by using the same bolts and nuts.

[0029] In order to better relieve the pressure and divert the incoming water, the water diversion pipe 3 is arranged along the length direction of the water-sowing basin 1, and multiple drainage ports 32 are evenly distributed on the side of the water diversion pipe 3 facing the water-sowing basin 1. Optionally, the water inlet is located in the middle of the water diversion pipe 3. The water inlet is set in the middle. After the incoming water enters the water diversion pipe 3, it flows to both ends of the water diversion pipe 3 simultaneously. Compared with the method in which the water inlet is set at either end, the diversion effect is better. Optionally, the front and rear ends of the water diversion pipe 3 are both provided with sealing plugs. The sealing plugs can be blocked by pipe plugs or welded and sealed by sheet metal parts. The specific setting can be selected according to actual needs.

[0030] Combination Figures 2 to 4 , multiple drain ports 32 are arranged at intervals along the length direction of the water distribution pipe 3. In this embodiment, the multiple drain ports 32 are arranged in two vertical columns. In other embodiments, they can be arranged in three or more vertical columns. Preferably, two vertical columns are arranged, and the two vertical columns are mirror images of each other.

[0031] In order to achieve the pressure relief effect, the angle between the central axis of each drain port 32 and the axial vertical plane of the water distribution pipe 3 is an acute angle ( Figure 4 As a preferred solution, the angle between the drain outlet 32 ​​and the vertical plane of the water distribution pipe 3 is 45 degrees, which can not only achieve the pressure relief effect, but also distribute the water more evenly, so that the incoming water is evenly distributed to various positions of the water-spreading basin 1.

[0032] Please see Figure 1 The inner bottom surface of the watering basin 1 is fixedly provided with a mounting bracket 4 for supporting the water distribution pipe 3. Optionally, a U-shaped groove is formed at the top of the mounting bracket 4. The mounting bracket 4 can not only play the role of limiting support, but also effectively reduce the vibration of the water distribution pipe 3 during water inlet, and avoid the phenomenon that the water distribution pipe 3 and the water inlet cover plate 2 are loosened.

[0033] The water inlet pressure relief device of this embodiment replaces the previous baffle pressure relief method by setting a water distribution pipe 3 to slow down the impact of water flow, which can effectively reduce the pressure of the water inlet, ensure the cooling performance of the cooling tower, and improve the cooling efficiency of the cooling tower. The water distribution pipe 3 can evenly distribute the incoming water to various positions of the water-spreading basin 1, ensure that the water level of the nozzle of the water-spreading basin 1 is as consistent as possible, improve the water-spreading capacity of the water-spreading basin 1, and thus improve the cooling performance of the cooling tower. The overall structure is simple and compact, the manufacturing cost is low, and it can effectively relieve the pressure and divert the incoming water.

[0034] Finally, it should be noted that the cooling tower water inlet pressure relief device disclosed in the embodiment of the utility model is only a preferred embodiment of the utility model, which is only used to illustrate the technical solution of the utility model, rather than to limit it.
