    摘要： A safety and regulation valve unit for a gas installation, particularly a heating installation, comprises a duct through which the fuel can flow between an inlet and at least one outlet. An on-off fuel-valve is interposed in the duct between the inlet and the at least one outlet, and there is a movable device for controlling the valve as well as an actuator acting on the movable device in order to move it towards a first operative position in which it cooperates with the on-off valve in order to put the inlet into communication with the outlet. The actuator comprises a reversible motor with a rotor connected to a male-and-female screw coupling acting on the movable device to translate it towards the first operative position and to control the on-off valve.

    摘要： A system is described for sealed connection between a pair of tubular sections (3, 2a) intended to convey a gaseous fluid under pressure, wherein the sections are capable of relative orientation from and towards a preselected positioning at which they are rigidly connected to each other with a sealed connection. The system comprises nesting coupling means, respectively provided on one and the other of the tubular sections coaxially engageable with each other, gastight sealing means between the tubular sections, axial checking means (6, 7) between the nesting coupling means for holding one of the tubular sections relative to the other section in the direction of mutual axial coupling (X). The system also comprises removable locking means (10) between the sections (3, 2a) for rigidly locking the tubular sections to each other in the state of preselected relative positioning, wherein the locking means (10) for the relative orientation between the sections are independent of the axial checking means (6, 7), such that the gastight seal is ensured in the state in which the tubular sections are freely orientable with respect to each other without any action of the locking means.
