Pressure vessel unit

Abstract

This technology reduces the manufacturing cost of pressure vessel units. [Solution] The pressure vessel unit comprises a plurality of pressure vessels with openings at both longitudinal ends, a first end plug provided on each pressure vessel which seals the opening at one longitudinal end and is provided with a fluid supply passage for supplying fluid to the pressure vessel, a second end plug provided on each pressure vessel which seals the opening at the other longitudinal end and is provided with a fluid discharge passage for discharging fluid from the pressure vessel, a connecting portion connecting the plurality of pressure vessels, and bolts which are detachably fixed to each of the second plugs and block the fluid discharge passages.
