    摘要： A ball valve that is suitable for large pipe sizes (e.g., 20-40 inches or larger). The body is fabricated by welding from mill steel shapes (e.g., plate steel). The main pressure-retaining part of the body is a generally cylindrical shell made from a plurality of segments welded together. At least one and preferably two of the segments are flat plates which are welded to one or two cylindrical segments. The flat plate or plates serve to mount bearing means for journalling the ball. One of the end portions of the body for making connection with associated piping includes an annulus secured to one end of the shell, together with a conical shaped section and a pipe section connected between the annulus and the small end of the conical section. The annulus serves to mount a sealing assembly for the valve.

    摘要： A gate valve body is formed from a U-shaped member wherein each leg and the bottom connecting portion of the U-shaped member have a substantially U-shaped cross-section. The arms of the U-shaped cross-section of each leg face each other. A filler plate having a concave bottom surface is extended across the front face of the U-shaped member downwardly from the free end of each leg and welded to a facing arm of each leg. A second similar filler plate is extended across the rear face of the U-shaped member and similarly welded. An attaching plate having a cut-out center portion is welded to the free ends of the legs of the U-shaped member and to the top surfaces of the filler plates. The bonnet portion of the valve is formed from a second U-shaped member wherein each leg and the upper connecting portion of the U-shaped member have a substantially U-shaped cross-section. The arms of the U-shaped cross-section of each leg face each other. A semi-circular filler plate is positioned across the front face of the member to fill the opening between the legs and is welded to a facing arm of each leg. A similar filler plate is welded similarly to the rear face of the member. A second attaching plate having a cut-out inner portion is welded to the free ends of the legs of the U-shaped member and to the bottom surfaces of the filler plates. A hole is provided in the center of the connecting portion of the U-shaped member.

    摘要： A gate valve suitable for applications where the pressure on one side of the valve is negligible or relatively low, while the pressure on the other side of the valve may be substantially higher. A resilient seal is provided between the end of the wall of the body and the gate on one side of the valve, namely that side which may have a substantial pressure applied. On the other side of the body, the body space is ported to the corresponding flow passage of the valve, whereby leakage from the higher pressure side cannot apply to the body.
