Embodiment Construction
[0026] In order to enable those skilled in the art to better understand the solutions of the present invention, the present invention will be further described in detail below in conjunction with specific embodiments.
[0027] The constant flow distribution device provided by the present invention is suitable for systems requiring stable flow branches in engineering practice, such as purely mechanical well deviation measurement tools.
[0028] Such as figure 1 As shown, the constant flow distribution device includes a branch adapter 12 and an induction turbine seat 6 , the induction turbine seat 6 is installed inside the branch adapter 12 , and the branch adapter 12 passes through the induction turbine seat 6 . The induction turbine seat 6 is covered with a composite bearing 3, and is connected to the main road connection seat 11 through the composite bearing 3, so that the induction turbine seat 6 can rotate around its central axis. The outer peripheral sleeve of the combine...

The invention discloses a constant flow dividing device which comprises a branch adapter, and an induction turbine is arranged in the branch adapter. The constant flow dividing device further comprises an upper dividing assembly and a lower dividing assembly, the upper dividing assembly comprises a centrifugal valve block, and the centrifugal valve block performs centrifugal movement according tothe rotating speed of the induction turbine; a flow passing hole is formed in one side of the centrifugal valve block, a first flow guide channel is formed in the other side of the centrifugal valve block, and the centrifugal valve block can move between the position where the first flow guide channel is closed and the position where the first flow guide channel is opened; the lower flow dividingassembly comprises a valve port, and a buffer spring, a valve port adjusting driving turbine, a valve port adjusting driving gear and a valve port adjusting executing gear which are arranged in the valve port.The valve port adjusting driving turbine corresponds to the flow passing hole or the first flow guide channel; The valve port adjusting drive turbine is in rigid connection with the valve port adjusting drive gear, the valve port adjusting drive gear is meshed with the valve port adjusting execution gear, and the buffer spring is used for achieving flexible connection between the valve port adjusting drive gear and the valve port adjusting execution gear.
Description
technical field [0001] The invention belongs to the technical field of engineering flow control, and in particular relates to a constant flow diversion device. Background technique [0002] At present, in the drilling and logging process of oil exploration and geological exploration, because the drilling depth is often relatively large, in order to ensure the normal operation of the drilling, the predetermined well trajectory and drilling depth can be achieved, and the required drilling depth can be obtained in this process. Borehole data, in the operation process, often requires a large number of downhole operation tools, and these tools will inevitably come into contact with drilling fluid during use, some of which simply realize the transition of fluid between upper and lower short nodes, while more tools are It works under the action of drilling fluids with different pressures or flows. In the design process of traditional downhole operation tools, it is often necessary ...
