Abstract
A rotational two valve disconnect apparatus including a first rotational valve, a second rotational valve, and a rotational disconnect structure connected to the valves. The valves on the disconnect structure are constructed so that the disconnect can be engaged to flowably connect the first and second valve and disconnected to separably disconnect the first and second valves. The structure is further designed so that a single rotational movement will engage the disconnect structure and open the first and second valves or an opposite rotational movement may close the first and second valves and then disengage the disconnect structure. The preferred embodiment utilizes a single rotational axis for both the first and second valves and the disconnect structure. A further design advantage includes radial ports to allow for reduced operating requirement for the valve in high pressure environments.
