Since the position of the external pipe is different, the position needs to be adjusted, and at this time, the third rotating pipe 24, the second rotating pipe 23 and the first rotating pipe 22 are rotated in turn, so as to facilitate the introduction of the flow object. In the rotating process of the first rotating pipe 22, the blocking block 25 in the first rotating pipe 22 is rotated. Since the blocking block 25 is also installed in the mounting pipe 21, when the two blocking blocks 25 are aligned, the flow holes 26 on the blocking blocks 25 are also aligned, so that the flow rate is maximum.

When it is needed to reopen it, the above operation is performed in reverse. In use, by screwing the mouth body 16 with the threaded groove 17 at one end to the first connecting seat 7, the flow object flows from the first connecting seat 7 to the mouth body 16, and in order to make the flow rate of the flow object uniform, the baffle 19 is installed in the mouth body 16 to block it, and the flow object flows along the flow hole 15 on the baffle 19, so that the flow is more uniform.

[0042] In use, when it is needed to introduce the external flow material into the pipe body 3, the third rotating pipe 24 is connected with the external pipe, so that the flow material flows into the pipe body 3 through the second rotating pipe 23, the first rotating pipe 22 and the installation pipe 21 in turn, so as to complete the introduction process of the flow material, and since the position of the external pipe is different, the position needs to be adjusted, at this time, the third rotating pipe 24, the second rotating pipe 23 and the first rotating pipe 22 are rotated in turn, so as to facilitate the completion of the introduction process of the flow material, and in the rotating process of the first rotating pipe 22, the blocking block 25 in the first rotating pipe 22 is rotated, since the blocking block 25 is also installed in the installation pipe 21, when the two blocking blocks 25 are aligned, the flow hole 26 on the blocking block 25 is also aligned, at this time, the flow rate is maximum.
