Water hammer-resistance damping device of pipeline

Abstract

The invention discloses a water hammer-resistance damping device of a pipeline. The damping device is connected to the tail end of the pipeline and comprises a connecting body, a horn-shaped channel which is through front and back is formed in the connecting body, the small end of the channel is an inlet end, the large end of the channel is an outlet end, the inlet end of the channel is in sealedbutt joint with the tail end of the pipeline, a buffer block is arranged at the position, close to the outlet end, in the channel, the inner end of the buffer block extends into the channel and makescontact with the inner side wall of the channel in a sealed mode, a buffer cavity is formed in the middle of the outer end of the buffer block, a through hole and a plurality of blind holes are formedin the bottom of the buffer cavity, the buffer cavity communicates with the channel of the connecting body through the through hole, and the outer end of the buffer block extends out of the outlet end of the channel and blocks the outer end of the buffer cavity through a blind plate. The device has the advantages that the water hammer phenomenon can be effectively prevented and relieved, and a pipeline system is protected.

Description

technical field [0001] The invention relates to a pipeline anti-hammer damping device. Background technique [0002] During the pipeline transportation of water or other liquid media, water hammer phenomenon often occurs, also known as "water hammer phenomenon". At the moment of water hammer, the pressure can reach dozens or even hundreds of times of the normal working pressure in the pipeline. This large pressure fluctuation will produce a huge impact along the medium at the blind end of the pipeline, which can cause strong vibration or noise in the pipeline system, which will have a great destructive effect on the pipeline system, and even affect the entire pipeline in severe cases. safe operation of the system. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a pipeline water hammer damping device, in order to effectively prevent and slow down the water hammer phenomenon and protect th...
