Title:
SELF-ADAPTIVE IRRIGATION SYSTEM PIPELINE WATER HAMMER IMPACT REDUCING DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/248835
Kind Code:
A1
Abstract:
A self-adaptive irrigation system pipeline water hammer impact reducing device, comprising a valve inlet pipeline (1), a reducer (4), and a water hammer response channel. The reducer (4) and the outer wall of the valve inlet pipeline (1) form a closed annular cavity; the edges of an isolating reinforcement plate (21) are respectively connected to the inner wall of the reducer (4) and the outer wall of the valve inlet pipeline (1); a pressure relief action block (8) is attached to the inner wall of the reducer (4) and the outer wall of the pipeline, the isolating reinforcement plate (21) and a first end surface of the pressure relief action block (8) form a pressure relief cavity, a water discharging port is formed in the pressure relief cavity, the isolating reinforcement plate (21) and a second end surface of the pressure relief action block (8) form an action cavity, and the water hammer response channel is in communication with the action cavity and an inner cavity of the valve inlet pipeline (1); a pressure relief hole (11) and a pipeline hole (18) are completely staggered under a normal water conveying state, and the pressure relief hole (11) is in communication with the pipeline hole (18) under a pressure relief state. The water hammer impact reducing device can actively respond the water hammer impact of a valve in an irrigation water distribution pipe network, effectively reduce the water hammer impact, guarantee the safety of key components of the irrigation water distribution pipe network, and improve the stability of an irrigation water distribution system, and is applicable to a multi-user random irrigation water distribution pipe network working condition.
