Abstract

A valve assembling apparatus is provided to shorten time taken for assembly, by easily compressing components of an axial flow valve through the operation of a hydraulic jack. A valve assembling apparatus includes a lower fixed plate(20), a plurality of guide rods(51,52), an upper fixed plate(30), an elevating plate(40), and a hydraulic jack(60). The guide rods stand upright onto the lower fixed plate. The upper fixed plate is fixed on the guide rods, and has a center with an assembly hole(32). The elevating plate is coupled to the guide rods such that the elevating plate is movable. The elevating plate has a center with a bolt support portion(41) for supporting a bolt(14). A main body of an axial flow valve, a rubber sleeve, and an upper closure and a lower closure are mounted on the elevating plate for tightening with the bolt. The hydraulic jack is mounted on the lower fixed plate, and permits the elevating plate to move in a vertical direction. When the hydraulic jack operates, the elevating plate elevates, and the rubber sleeve and the upper and lower closures are compressed and joined with each other between the upper fixed plate and the elevating plate, to thereby tighten a nut to the bolt through the assembly hole.
