Description

TECHNICAL FIELD

[0001] The utility model relates to simulation device technical field especially relates to a building inner water tap water hammer simulation device. BACKGROUND

[0002] When the user uses the water tap, water throttles at the valve core position, which can cause the flow rate to increase and the pressure to drop. When the pressure is less than the saturated vapor pressure of the liquid, the liquid appears vaporization. After the water flows through the valve core, the flow rate drops, and the pressure recovers. If the pressure rises above the saturated vapor pressure of the liquid, the original cavitated gas is restored to the liquid state, and the rupture of the bubbles will generate a huge amount of energy. If a large number of bubbles rupture at the same time, it will cause the formation of impact pressure, which can reach thousands of times of the normal working pressure. This large pressure will cause the material of the water tap to deform, and at the same time, a small area of damage is caused. With repeated fatigue damage, the water tap is eventually damaged, and the instantaneous pressure can cause the pipeline system to produce strong vibration and noise.
