Audited Supplier The working characteristics of the check valve are the large load change, the small opening and closing frequency, once it is put into the closed or open state, the applicable period is very long, and the movement of moving parts is not required. But once there is a "switching" requirement, it must be flexible. This requirement is more demanding than common mechanical movements. [2]
In most practical applications, check valves are qualitatively determined to be used for fast closing. At the moment when the check valve is closed, the medium flows in the direction. As the valve flap is closed, the medium quickly drops to zero from the maximum backflow velocity. , And the pressure rises rapidly, that is, the phenomenon of "water hammer" that may have a destructive effect on the pipeline system is generated. [2]
For high-pressure piping systems where multiple pumps are connected in parallel, the water hammer problem of check valves is more prominent. Water hammer is a kind of pressure wave in the transient flow in the pressure pipeline. It is the hydraulic shock phenomenon of the pressure rise or fall caused by the change of the fluid velocity in the pressure pipeline. The physical reason is the combined effect of fluid incompressibility, fluid motion inertia and pipeline elasticity. In order to prevent the hidden danger of water hammer in pipelines, for many years, people have adopted some new structures and new materials in the design of check valves to ensure the applicable performance of the check valve while minimizing the impact of water hammer.
