Title:
PIPE AIR PRESSURE REGULATING DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/140870
Kind Code:
A1
Abstract:
A pipe air pressure regulating device, relating to the technical field of transportation, the pipe air pressure regulating device comprising a pipe (4) and at least one air pressure regulating assembly disposed at an outter side of the pipe (4). The pipe (4) is provided with an inner cavity used for transportation of a transport tool (5). Each air pressure regulating assembly comprises a breather pipe (1), air inlets and air outlets of the breather pipes (1) communicate with the inner cavity of the pipe (4), and the breather pipes are used for adjusting the air pressure difference between the front and rear of the transport tool. The present device reduces the air pressure difference between a front portion and a rear portion of the transport tool in the process of the transport tool traveling in the pipe and reduces the travel resistance of the transport tool. At the same time, the symmetrical stress caused to the pipe wall by the pressure difference between the front portion and the back portion of the transport tool is reduced, thus having the effect of the pipe being protected. The present device may continuously extrude the residual air in the pipe by means of the traveling of the transport tool, so that the travel resistance of the transport tool is as low as possible.
