Claims

[Scope of utility model registration request]

A bleed passage 12 for discharging non-condensable gas to the outside is connected to the can body 1 whose internal pressure is below atmospheric pressure, and the bleed passage 12 only allows gas to flow from the can body 1 to the outside. A check valve 13 and a bleed pump 14 for discharging gas are interposed such that the check valve 13 is located on the upstream side of the discharge flow, and the check valve 13 and the bleed pump 14 are connected to each other in the bleed passage 12. A vacuum boiler bleeder is provided with a valve means for communicating and shutting off an intermediate portion 12a located between the outside and the outside, wherein the valve means is configured to connect the intermediate portion 12a to the outside. A branch path 15 is connected to the intermediate portion 12a, and the branch path 15 is connected to the intermediate portion 12a.
A vacuum boiler bleed device that is equipped with an on-off valve 16.
