The invention discloses a pressure transfer eccentric water distribution blanking plug. The blanking plug comprises a lower main body and an upper main body which is connected with the lower main body, wherein the upper main body is connected with the lower part of a fishing rod; the lower main body is provided with a pressure transfer hole I along the axial direction; the upper main body is provided with a pressure transfer hole II along the axial direction; the lower part of the fishing rod is provided with a central hole along the axial direction; the middle part of the fishing rod is provided with at least two seal rings between which a necking section is arranged; a pressure transfer hole III is formed in the necking section; the pressure transfer hole I, the pressure transfer hole II and the central hole are communicated with the pressure transfer hole III; a spring is sleeved outside the lower part of the fishing rod; the front end of the spring is provided with a pressure transfer sleeve; the front end of the pressure transfer sleeve is provided with a through hole III along the radial direction; the fishing rod is positioned in the pressure transfer sleeve; the front end of the fishing rod is connected with a pressure transfer joint in which a pressure transfer hole IV is formed; and the pressure transfer hole IV is communicated with the through hole III. Through the blanking plug, the aim of simultaneously performing underground layered flow testing and seal examination testing is fulfilled during normal water injection of an eccentric layered water injection well.

The invention provides a quick phase-splitting switcher for an alternating-current loop and relates to the technical field of AC commutation. The switcher comprises a housing, input binding posts, anoutput binding post, a rotating knob, a rotating shaft, a moving contact, and a static contact. The housing is cylindrical, and the rotary knob is connected with the housing. The rotating shaft is provided with a moving contact, and the rotating knob is connected with the rotating shaft and the moving contact is driven to do axial movement around a central axis of the housing. The input binding posts comprise an A-phase binding post, a B-phase binding post, a C-phase binding post and an N-phase binding post and are arranged on a cylindrical side surface of the housing, and the output binding post is arranged on a bottom surface of the housing and is connected with the rotary knob. The connection of different static contacts is achieved by rotating the rotating knob, and therefore, the phase switching is achieved. Through the phase-splitting switcher provided by the invention, the problem that interfaces of a four-phase alternating-current loop and a two-phase detection instrument do not correspond to each other can be solved, the operation intensity of workers is reduced, and the processes of the connection of a measurement instrument into the alternating-current loop and an alternating-current loop detection test are simplified.

The invention relates to a process of roving wool fabric. According to the wool fabric produced through the process of roving wool fabric, product damage can be greatly reduced, pilling is reduced, elasticity is high, stability is high, dryness test can be completed within a short period of time, the test result is rapid and timely, water absorption fabric production and technology can be easily checked by enterprises, test process is simple and practicable, no special detecting device needs to be arranged, and test cost is low.
