Abstract: A bladder-type pressure tank includes an outer shell, a bladder, a nozzle, and an elbow pipe. The outer shell includes a liner and a glass-fiber layer covering the outer surface of the liner. The liner includes polyethylene (PE). The liner further includes a chamber, a first opening, and a second opening. The bladder is disposed in the chamber. In an inflated state of the bladder, a gap is formed between the inflated bladder and the inner surface of the liner. The bladder includes polyurethane (PU). The nozzle is integrated with the bladder, and is disposed in the first opening and seals the first opening. The elbow pipe includes a first end and a second end. The first end of the elbow pipe is disposed in the second opening and communicates with the chamber; and the second end of the elbow pipe is configured to connect to a pipeline.
