Description

Pipe elbow with deflector

Technical Field

The utility model relates to the technical field of air conditioners of water chilling units, in particular to a pipeline elbow with a guide plate.

Background

The water impact is also called a water hammer, and is a phenomenon that a pipeline or a container carrying the water to flow generates sound and vibration due to the impact force generated by the water suddenly. The water hammer phenomenon is extremely destructive: too high a pressure will cause the pipe to collapse, whereas too low a pressure will result in collapse of the pipe and damage to the valve and fixtures. The pump-stopping water hammer is a water hammer phenomenon, and is a hydraulic impact phenomenon that a series of sharp pressure alternately rises and falls in a water pump and a pipeline system caused by sudden change of flow velocity when a water pump unit suddenly stops in a valve opening state caused by sudden power failure or other reasons.

When the quick-closing check valve is used at the outlet of the water pump to prevent water hammer, the movement direction of water can be greatly changed due to the pipe elbow arranged at the outlet of the water pump, and the generated turbulence can influence the work of the quick-closing check valve, so that the closing time exceeds the minimum time of the water hammer, and the water hammer cannot be well eliminated.
