  • Safety lock for a gate valve
    Patent number: 9746099
    Abstract: There is provided a safety lock for a hose connector and valve on a flow line having an anchor that is in a fixed position relative to the valve, a movable body movably attached to the anchor, and a shroud and an actuator blocking member carried by the movable body. The shroud is sized and positioned on the movable body to limit access to the hose connector when the movable body is in a first position, and to permit access to the hose connector when the movable body is in a second position. The actuator blocking member is sized and positioned on the movable body to prevent the valve actuator from moving from a second to a first position when the movable body is in the second position, and to permit movement of the actuator when the movable body is in the first position.
