the method comprises the following steps: firstly, drilling a hole at a proper position of a plane, taking down a fixing bolt (17) in a direction adjusting mechanism 1, attaching a surface where a second chuck (15) in the direction adjusting mechanism 1 is located to the plane, aligning the middle part of the second chuck (15) with the drilled hole, mounting the fixing bolt (17), and fixing a starting pipe joint on the plane by using the fixing bolt (17);
step two: after the pneumatic pipe joint is fixedly installed, the pneumatic pipe is connected, the pipe connecting mechanism (2) is rotated, the interface branch pipe (9) rotates to a proper direction around a bearing (18) on the peripheries of a first chuck plate (14) and a second chuck plate (15), then the sealing cover (11) is taken down, the pneumatic pipe is sleeved on the position of the adjusting inner pipe (10) exposed outside the interface branch pipe (9), then the fixing ring (4) in the fixing mechanism (3) is sleeved on the periphery of the pneumatic pipe and corresponds to the position of the ring groove (12), then one end of the fixing ring (4) is inserted into the slot (7) in the ring sleeve (6) and penetrates out, the fixing ring (4) is pulled forcefully to enable the fixing ring (4) to clamp the pneumatic pipe, the pipe wall of the fixing ring (4) and the pneumatic pipe is embedded into the ring groove (12), then the fixing screw (5) is installed, and the fixing screw (5) penetrates through the two layers of the fixing rings (4) which are overlapped together and then is connected with the fixing screw hole (13) in a threaded manner, then cutting off the redundant fixing ring (4);
step three: after the pneumatic pipe is installed, after fluid flows into a pneumatic pipe joint from the pneumatic pipe, the fluid preferentially enters one of the interface branch pipes (9), then sequentially passes through the adjusting inner pipe (10) and the flow limiting mechanism (19), finally flows to the central ring pipe (8), and then flows to the other three interface branch pipes (9) from the central ring pipe (8), in the process, because the pneumatic pipe has stronger flexibility, the adjusting inner pipe (10) is rotated, in the process that the adjusting inner pipe (10) moves outwards, the elastic potential energy released by the compressed flow limiting spring (22) in the flow limiting mechanism (19) is converted into kinetic energy, the flow limiting inner pipe (21) is driven to move towards the direction of the adjusting inner pipe (10) along the direction of the interface branch pipes (9), meanwhile, the flow limiting inner pipe (21) drives the first sealing ring (20) to be attached to the adjusting inner pipe (10), the sealing performance in the moving process is ensured, and the distance between the flow limiting inner pipe (21) and the second sealing ring (23) is continuously increased in the moving process, the fluid flow path of the central ring pipe (8) and the adjusting inner pipe (10) is communicated, the fluid flow in unit time is continuously increased along with the increase of the distance, the moving distance of the adjusting inner pipe (10) along the interface branch pipe (9) is required to be adjusted in the process of rotating the adjusting inner pipe (10), and the adjusting inner pipe (10) is prevented from being separated from the interface branch pipe (9) due to overlarge amplitude.
