Abstract

PURPOSE:To secure such a control valve pressure jig that is easy in structure and inexpensive in cost by forming the control valve pressure jig to be installed in place of a seat ring and a retainer from a blind pluglike pressure proof seat plug. CONSTITUTION:A cage 3 provided with a flow hole 3a is set up in the point midway in a fluid passage of a body 1. In this cage 3, there is provided with a plug 4 free of vertical motion. A pressure proof sheet plug 30 is screwed in an internal thread part 1c at the side of the body 1 in place of a seat ring and a retainer at the time of pressure proof tests. At the time, a seat gasket 13 is inserted into space between the primary side of the body 1 and a lower end of the pressure proof seat plug 30, and an interval between both is interrupted in terms of withstanding pressure.
