Hereinafter, the present invention will be specifically described with reference to the drawings.
図１の形態において、散気体ホルダー１は、水平方向右方向に伸びた筒状部分を有する。この筒状部分の右側に、図示しない散気体がホルダーと接続される。散気体ホルダー１は、筒状部分の下方（図では左側）に半円筒部分（断面図では、半円周状）が一体に形成されている。半円筒部分の外面に半円筒部分の径方向に接続（一体に形成）されている。半円筒部分の内面（断面図では左側）は空気供給用配管と接している。 In the form of FIG. 1, the air diffuser holder 1 has a cylindrical portion extending rightward in the horizontal direction. A diffused gas (not shown) is connected to the holder on the right side of the cylindrical portion. The air diffuser holder 1 is integrally formed with a semi-cylindrical portion (a semicircular shape in the cross-sectional view) below the cylindrical portion (left side in the figure). The outer surface of the semi-cylindrical part is connected (formed integrally) in the radial direction of the semi-cylindrical part. The inner surface (left side in the sectional view) of the semi-cylindrical portion is in contact with the air supply pipe.
半円筒部分の内面には、凸部状空気供給口３が半円筒部分と一体に形成されており、凸部状空気供給口３の軸方向と、筒状部分の軸方向とが同一方向になるように形成されている。凸部状空気供給口３の径は、空気供給用配管４に設けられた穴とほぼ同じ径であり、散気体ホルダー１を空気供給用配管４に取り付ける際には、凸部状空気供給口３が配管の穴に差し込まれ、密着するようにする。供給される空気は、配管から、配管と連通している凸部状空気供給口３に入り、図１の右方向に流れ、散気装置に供給されることになる。 A convex air supply port 3 is formed integrally with the semicylindrical portion on the inner surface of the semicylindrical portion, and the axial direction of the convex air supply port 3 and the axial direction of the cylindrical portion are the same direction. It is formed to become. The diameter of the convex air supply port 3 is substantially the same as the diameter of the hole provided in the air supply pipe 4, and when the diffuser holder 1 is attached to the air supply pipe 4, the convex air supply port 3 is inserted into the hole of the pipe so that it is in close contact. The supplied air enters the convex air supply port 3 communicating with the pipe from the pipe, flows to the right in FIG. 1, and is supplied to the air diffuser.
凸部状空気供給口３が配管の穴に差し込まれる時、凸部状空気供給口３の外面には、０―リング又はリング状パッキン２が取り付けられている。散気体ホルダー１が空気供給用配管４に取り付けられる時、図１のように、０―リング又はリング状パッキン２が、空気供給用配管４と散気体ホルダー１の間の機密性を保つ位置にある。 When the convex air supply port 3 is inserted into the hole of the pipe, the 0-ring or ring packing 2 is attached to the outer surface of the convex air supply port 3.
