けたことを特徴とする耐圧試験用盲蓋。 The blind lid closes the open end of the pipe, and the inner cylinder serving as the blind lid main body has a bottom portion in the inner part of the pipe insertion portion that comes into contact with a rubber stopper that closes the open end of the pipe, and the pipe insertion portion A tapered hole is drilled in the inner and outer circumferential directions in which a lock ball can be inserted and retracted, and the lock ball comes into contact with the outer circumference of the main part of the pipe and the outer circumference of the small-diameter opening end, respectively. A conical surface portion having a smaller diameter is provided on the outer periphery of the inner cylinder, and a slide is provided on the outer periphery of the inner cylinder and is slidable on the same surface and is always urged in the direction opposite to the tapered hole position and fitted into the rear part of the inner cylinder. The inner cylinder and the ring stopper cylinder have a tapered surface formed on the inner peripheral surface of the tip opening facing the conical surface of the inner cylinder, and an inner peripheral surface of the rear end opening slidably fitted onto the slide inner cylinder. A ring with a tapered surface that presses the second locking ball against the outer peripheral surface of the small diameter opening of the pipe is fitted between the inner tube and the outer tube so as to face the ring retaining cylinder. A coil spring is installed on the outer periphery of the inner cylinder to urge the inner cylinder and the slide inner cylinder in opposite directions, and a coil spring is provided to press the ring toward the second lock ball. A blind lid for pressure testing, characterized by having a stopper that regulates the maximum retraction position of the lid.
