タービンケーシング。[Scope of Claim for Utility Model Registration] 1. An upper casing and a lower casing are joined to each other via flanges provided on them, and the joined upper and lower flanges are tightened with a plurality of bolts, and each flange is provided with a hole. In a turbine casing, adjacent bolt insertion holes are connected to each other by communication holes, and the bolts are cooled by flowing low-temperature steam through the communication holes. Holes are drilled in the upper and lower flanges, respectively.
Furthermore, the turbine casing is characterized in that the communication holes in the lower flange communicate with each other at least at the flange joint surface. 2. The communication hole in the upper flange and the communication hole in the lower flange are opened at different positions on the joint surface of the flange, and each opening is connected to a groove provided in the joint surface of at least one of the upper flange or the lower flange. A turbine casing according to claim 1 of the connected utility model registration claims. 3 Utility model registration in which one end of each communication hole in the upper and lower flanges directly communicates with one of the communicating bolt insertion holes, and the other end of the communication hole communicates with the other bolt insertion hole through a groove. A turbine casing according to claim 2. 4. The communication hole or groove is located on the inside or outside of the casing and is connected to the bolt insertion hole in a tangential direction as claimed in any of claims 1, 2, or 3 Turbine casing as described in.
