    摘要: A ball valve in which the ball of the valve is positively prevented from blowing out of the valve body in both directions, even if the valve is connected in the wrong direction or the fluid pressure is applied to the valve in the opposite direction. The ball is arranged in a valve body to selectively open and close a fluid passage in the body, and annular seals abut against the ball from both sides of the fluid passage, the annular seals being pushed towards the ball by seal carriers. In one embodiment, one of the seal carriers has a flange on the periphery of one end thereof, and the flange is locked to a step from inside which is formed on inner surface of one end portion of the valve body. In a second embodiment, the ball additionally has two grooves with abutting walls in respective ones of which a spindle and a pin coaxial with the spindle are fitted with the abutting walls positioned on the side of the one seal carrier.

    摘要: A branched valve includes a main flow passage and a branch flow passage provided in a main body, a weir provided between the main and branch flow passages, and a valve disc which can contact with and come off from the weir and which selectively connects and disconnects the main and branch flow passages, wherein a branch flow entrance wall of the branch flow passage integrated with the weir has either a flat surface or a convex surface. The outer wall of the branch flow exit of the main flow passage may rise vertically from the outer wall of the main flow passage, and the side wall of the weir is located approximately on the center line of the main flow passage. The branch flow passage may be provided so that the center line thereof is located higher than the center line of the main flow passage. The valve disc may be a diaphragm.

    摘要: A stop valve includes a main body which defines a fluid passage and a valve chamber. The stop valve further includes a spindle having one end connected to a handle and the other end inserted into said valve chamber, a valve seat positioned in said fluid passage and confronting said valve body, and a cap member positioned above said valve chamber. The outer end of the spindle is coupled rotatably to the valve body, while the rotation of the valve body is prevented by a rotation preventive means. A packing is interposed between the valve body and the valve chamber. The valve body is in sliding contact with said packing along the axial direction thereof during operation, upon rotation of the spindle about its axis.
