Description

Pulse damper Technical Field The utility model belongs to the technical field of pulse dampers, and particularly relates to a pulse damper. Background The pulse damper is a pressure vessel for eliminating the pressure pulsation or flow pulsation of the liquid in the pipeline, and can play roles of stabilizing the pressure and flow of the liquid, eliminating the vibration of the pipeline, protecting downstream instruments and equipment, increasing the volumetric efficiency of the pump, and the like. The diaphragm type pulse damper is one of the more common pulse dampers, the corrosion-resistant diaphragm is used for isolating gas from liquid in a pipeline, and pipeline pulsation is smoothed through the change of the volume of an air chamber, so that the harm of a water hammer to a system is reduced, the peak value of flow velocity fluctuation is reduced, the pipeline and a valve joint are protected from the impact of pressure fluctuation, and the energy consumption of the system is reduced. The Chinese patent with the publication number of CN222797636U discloses a diaphragm type pulse damper, which comprises a diaphragm type pulse damper main body, wherein a connecting port is communicated with the top and the bottom of one side of the diaphragm type pulse damper main body and is used for connecting a pipeline, a hollow pipe is fixedly arranged at the top of the diaphragm type pulse damper main body, a hollow pipe sleeve is sleeved outside a first connecting port, a sleeve is arranged at the top of the hollow pipe, and a first semicircular groove communicated with the top of the hollow pipe is formed between the bottom of the sleeve and the top of the hollow pipe. According to the utility model, the diaphragm type pulse damper main body instrument, the connecting port and the pipeline are protected at the top of the diaphragm type pulse damper main body through the sleeve and the hollow pipe, so that the connection firmness of the pipeline and the connecting port can be improved, leakage is prevented, then the connecting port and the pipeline at the bottom of the diaphragm type pulse damper main body are protected and prevented from leakage by utilizing the two semicircular shells, and the sleeve and the hollow pipe are connected by utilizing a plurality of first hasps, so that the sleeve is convenient to detach and overhaul; However, when in actual use, the above-mentioned comparison document needs to fixedly connect the hollow tube with the pulse damper body, which affects the later maintenance, if the hollow tube is damaged, the pulse damper cannot be used or the use of the pulse damper needs to be stopped to repair the hollow tube, and the repair process is more troublesome.
