Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-4, the present invention provides a technical solution: a four-way pipe capable of monitoring flow velocity and flow direction comprises a four-way pipe 1, a pipe section 2 and a pitot tube 3, wherein the pipe section 2 is connected with the four-way pipe 1 at the upper part, the lower part, the left part and the right part of the pipe section 2 respectively, the pitot tubes 3 arranged at the two sides of the pipe section 2 are in central symmetry with each other, a partition plate 4 is arranged at the middle part in the pipe section 2 corresponding to the pitot tube 3, check valves 5 are arranged at the left side and the right side of the inner wall of the pipe section 2 corresponding to the partition plate 4, the check valves 5 are in central symmetry with each other, the pitot tube 3 comprises a transparent pipe body 31, a full-pressure connecting post 32, a static-pressure connecting post 33, a communicating pipe 34 and a full-pressure pipe 35, the transparent pipe body 31 is connected to the outer wall of the pipe section 2 through the full-pressure connecting post 32 and the static-pressure connecting post 33, the full-pressure connecting post 32 is communicated with the transparent pipe body 31, the static-pressure connecting post 33 is directly communicated with the transparent pipe body 31, the full-pressure connecting column 32 is communicated with the inner side of the pipe section 2 through a full-pressure pipe 35, the static pressure connecting column 33 is directly communicated with the inner side of the pipe section 2, the full-pressure connecting column 32 is close to the check valve 5 on the corresponding side, scales are arranged on the transparent pipe body 31, and the transparent pipe body 31 is filled with gas.

When the device works, when the medium flows upwards, the medium can flush the check valve 5 arranged on the left side of the partition plate 4, the fluid close to the pipe wall of the pipe section 2 is regarded as static fluid (static pressure), the static pressure can pass through the static pressure connecting column 33 and is subtracted from the full pressure communicated from the full pressure pipe 35, the full pressure connecting column 32 and the communicating pipe 34, and then the static pressure enters the transparent pipe body 31, and the transparent pipe body 31 is filled with certain gas to prevent the pressure fluid from directly flowing into the transparent pipe body 31; the check valve 5 provided on the right side of the partition plate 4 prevents the medium from flowing therethrough, but the fluid flowing from the left side flows to the pitot tube 3 on the right side, but the medium does not pass through the check valve 5, so that the medium is stationary at the check valve 5, the flow rate measured by the pitot tube 3 on the right side is 0, and the medium does not enter the transparent tube on the right side.
