Warm seawater pump station water hammer prevention device for LNG (Liquefied Natural Gas) station gasifier

The invention belongs to the technical field of water hammer prevention, and particularly relates to a warm seawater pump station water hammer prevention device for an LNG station vaporizer, the warm seawater pump station water hammer prevention device comprises a conveying pipeline, the water inlet end of the conveying pipeline is communicated with the water outlet end of a water pumping assembly, the water inlet end of the water pumping assembly is communicated with the water outlet end of a water collecting part, and the water inlet end of the water collecting part is communicated with the water outlet end of a warm seawater inlet pipe; one side of the middle of the conveying pipeline communicates with the water inlet end of a constant-pressure backflow assembly, and the water outlet end of the constant-pressure backflow assembly communicates with the middle of the water collecting part. When the pressure in the conveying pipeline is larger than the constant pressure value, the constant pressure backflow a
