Composite generation device based on direct-current water flow pulse vibration

Abstract

A composite generating device based on direct-current water flow pulse vibration relates to the technical field of fluid power machinery and comprises a tee joint, a first port of the tee joint is connected with a water outlet pipe, a second port of the tee joint is sleeved with a sealed elastic telescopic structure, and a third port of the tee joint is connected with a water inlet component. The inner top of the sealed elastic telescopic structure is connected with a plugging structure connecting rod, and the lower end of the plugging structure connecting rod is connected with a plugging structure used for plugging a water inlet port of the water outlet pipe. During intermittent and regular acceleration or deceleration of water flow in the plugging structure and the sealed elastic telescopic structure, the internal average water pressure is larger than the water pressure of straight-flow water due to the action of the water hammer, so that the water flow speed of discharged water is larger than the water outlet speed of the straight-flow water; due to the fact that the water flow of the pulse water is discontinuous, and the water flow of the straight-flow water is continuous, the flow of the pulse water flow is smaller than that of the straight-flow water under the conditions of the same water pressure, the same water outlet caliber and the same water outlet time, and the purpose of saving water is achieved.
