Abstract

PURPOSE: To enable a smooth bleeding of air in a line, by a method wherein, in a small-sized piping around a nuclear reactor, a fluid path part and a plurality of valve mechanisms for air bleeding are constructed in one body to reduce an installtion space.
CONSTITUTION: Where operations necessary to bleed air in a line are performed, caps 48 and 49 are removed after a plug 51 is taken out and a drain line is connected to an exhaust port 50 for air bleeding, and an upper end 32B of a stem 32 is spun gradually, which causes a valve to open to a full capacity. With an upper end 33B of a stem 33 then spun slowly, a valve is opened to a full capacity, and air gathering in a drainage path 26, a fluid path 23, and an inlet port 21 or an outlet port 22 is discharged to the outside from the exhaust port 50 for air bleeding. As described above, the fluid paths 23, 26, and 27, and valve mechanisms are formed in one body, and this allows to reliably perform operations necessary to bleed air at a limited space whereat lines are arranged densily.
