[0002] In water conservancy projects and water supply systems, water hammer is a long-standing technical problem. It is caused by the sudden change of water flow velocity in the pipeline, which causes transient pressure, which may lead to serious consequences such as pipeline rupture, leakage, and equipment damage.

[0003] Existing water hammer prevention devices, such as water hammer eliminators, air valves, and pressure regulating towers, have their own advantages, but they also have obvious limitations. For example, although water hammer eliminators can effectively eliminate water hammer phenomena, they are expensive, large in size, and take up a lot of space. In addition, they may generate noise during use, affecting the surrounding environment and residents' lives. Although air valves can balance the pressure in the pipeline and prevent gas accumulation, their regulating effect is greatly affected by environmental factors, and they may not work effectively under some special working conditions. Pressure regulating towers are more suitable for pipeline systems with large flows and low lifts, and may not work properly in cold areas.

[0026] like Figure 1-Figure 3 As shown, the water hammer prevention device based on bypass modification of the utility model comprises a needle valve body 1 and an adjusting member 2. The water in the pipeline is diverted by connecting the needle valve body 1 to the pipeline bypass, which effectively eliminates the water hammer phenomenon. The adjusting member 2 extends into the needle valve body 1 to adjust the size of the water flow passing through the needle valve body 1. The size of the water flow passing through can be accurately adjusted according to actual needs, thereby enhancing the adaptability of the equipment, optimizing the water flow distribution under different working conditions, further reducing the risk of water hammer, and improving the stability and convenience of the device.

[0027] The needle valve body 1 adopts a "T"-shaped structure, with openings at three ends, one opening for water inlet, one opening for water outlet, and the other opening for the adjusting member 2 to extend into. A placement groove and an adjusting hole are provided inside the needle valve body 1, and an internal thread is provided in the adjusting hole. The screw 6 is threadedly connected to the adjusting hole, and the adjusting member 2 passes through the adjusting hole and extends into the placement groove inside the needle valve body 1.
