Detailed Description

The following describes the automatic switching system of the compressor station pipeline in detail with reference to the attached drawings.

As shown in fig. 1, the automatic pipeline switching system for the compressor station comprises an air compressor 1, a first main pipeline 2, a second main pipeline 3, a third main pipeline 4, a first branch pipeline 5 and a second branch pipeline 6, wherein the output end of the air compressor 1 is connected with the first main pipeline 2, the first branch pipeline 5 is communicated with the first main pipeline 2 and the second main pipeline 3, and the second branch pipeline 6 is communicated with the second main pipeline 3 and the third main pipeline 4; an air filter 15 and an air dryer 16 are arranged on the first main pipe 2 in sequence along the air output direction, and the air filter 15 and the air dryer 16 are arranged between the first branch pipe 5 and the air compressor 1. A first pressure sensor 7 and a first valve 8 are sequentially arranged on the first main pipeline 2 along the air output direction, a second pressure sensor 9 and a second valve 10 are sequentially arranged on the second main pipeline 3 along the air output direction, and a third pressure sensor 11 and a third valve 12 are sequentially arranged on the third main pipeline 4 along the air output direction; the first pressure sensor 7, the first valve 8, the second pressure sensor 9, the second valve 10, the third pressure sensor 11 and the third valve 12 are electrically connected; the connection of the first partial pipe 5 to the first main pipe 2 is located between the first pressure sensor 7 and the air compressor 1, and the connection of the second partial pipe 6 to the second main pipe 3 is located between the second pressure sensor 9 and the first partial pipe 5.

Setting the first main pipe 2 as a high-pressure pipe, the second main pipe 3 as a medium-pressure pipe, and the third main pipe 4 as a low-pressure pipe, i.e., the pressure range in the first main pipe 2 is greater than the pressure range in the second main pipe 3, and the pressure range in the second main pipe 3 is greater than the pressure range in the third main pipe 4; the first branch pipe 5 is provided with a first pressure reducing valve 13, the second branch pipe 6 is provided with a second pressure reducing valve 14, and the pressure P1 behind the valve of the first pressure reducing valve 13 is higher than the pressure P2 behind the valve of the second pressure reducing valve 14, so that the stability of air pressure is ensured. For example, air having an air pressure in a high pressure range is directly circulated from the first main pipe 2, and the air having a pressure reduced after passing through the first pressure reducing valve 13 and the second pressure reducing valve 14 ensures that the air pressure in the second main pipe 3 and the third main pipe 4 is stabilized, while the air having an air pressure in a middle pressure range is passed through the first pressure reducing valve 13, and the first pressure reducing valve 13 serves as a passage.

Air is output to a first main pipeline 2 through an output end of an air compressor 1 and then reaches a second main pipeline 3 and a third main pipeline 4 through a first branch pipeline 5 and a second branch pipeline 6 respectively, then pressure in the respective main pipelines is monitored by a first pressure sensor 7, a second pressure sensor 9 and a third pressure sensor 11, and valves on the main pipelines with proper pressure are opened according to preset pressure values of the respective main pipelines, so that automatic switching among the main pipelines can be realized, the number of required standby machines can be reduced, and the purpose of reducing cost is achieved. For example, when the air pressure output from the air compressor 1 is within a preset medium pressure range, the first valve 8 in the first main pipe 2 and the third valve 12 in the third main pipe 4 are closed, and the second pressure sensor 9 in the second main pipe 3 detects that the air pressure is within the medium pressure range, the second valve 10 is opened, and air is circulated from the second main pipe 3.
