Abstract
PURPOSE: To permit a stopper ring to operate well and scatter a fire extinguishing liquid uniformly by forming a slit part at the peripheral side wall of an irregularly shaped pipe and also a locking part for the stop ring of a deflector at the bottom edge of the inner circumferential wall by means of the outer and inner diameter machining processes. CONSTITUTION: A base material for a frame is formed in an irregularly shaped pipe 1 equipped at the bore with a major diametric portion 3a and minor diametric portion 3b, where the minor part 3b is furnished with a semi-circular groove 4, and this pipe 1 undergoes a peripheral machining process. The minor portion 3b is furnished with a guide for a connecting rod 17 of a deflector 15 which consists of the semi-circular groove 4. Accordingly, the inner diameter machining includes only provision of a locking part 7 for a stopper ring 16, and no more processing for guide hole, etc., for the connecting rod 17 is required. Through the outer diameter machining of the pipe 1, it is possible to change freely the height of the slit 6, the width and height of the part 7, etc. These machining processes can be performed simply using an ordinary simple lathe.
