摘要： A collector circuit and associated circulation process, for intercepting and selectively diverting, at least partially, a fluid flow continuously flowing in a fluid circulation system, for drilling rigs. The collector includes a first sub-circuit with a first duct, with a first valve, and a second duct with a second valve; and; a second sub-circuit; The first sub-circuit, depending on the operating configurations of the first valve and the second valve, is adapted to allow the transit of the fluid flow in the first duct, and selectively divert fluid flow towards the second duct. The second sub-circuit is fluid-dynamically connected to the second duct of the first sub-circuit for receiving fluid flow, diverted by the first sub-circuit, and directing it towards a first outlet of the second sub-circuit. The second sub-circuit and the first sub-circuit are independent, and the second sub-circuit is removable from the collector circuit.

摘要： A valve assembly is for selectively opening and closing a radial aperture provided on a drilling element for drilling mud circulation. The valve assembly includes a valve body that has an inlet aperture and an outlet aperture, and a duct for putting the apertures in communication with each other, thereby defining a mud path (p). The valve assembly includes at least two shutters arranged in a cascade along the direction of the mud path (p), thus forming at least a double barrier.

摘要： A connection device for connecting a secondary drilling fluids circuit to a drilling element includes a radial aperture. A central body has a first connection portion forming a sealed connection to the secondary circuit. A second connection portion forms a sealed connection to the radial aperture and an intake duct conducts drilling fluids. A clamping system connects the connection device to the drilling element. One opening device is adapted to selectively open and close the radial aperture by acting upon a valve assembly. One coupling device connects the opening device to the valve assembly. The opening device selectively opens and closes the radial aperture by acting upon an obstructor of the valve assembly through rotary movement. The coupling device couples to a clamping element in the obstructor to transfer the rotary movement of the opening device to the obstructor to selectively and securely open and close the radial aperture.

The processing and control unit receives measurement data from the first measuring device and the second measuring device. The equipment includes a third control element having at least one third measuring device. The processing and control unit is electrically connected to the at least one third measuring device; it receives measurement data from the third measuring device, and processes the data thus obtained by a model-based mathematical algorithm.
