In real-world engineering applications, however, many conditions require that the position of the adapter outlet be changed after the media delivery is complete in order to facilitate disconnection from the pressure-containing member. To address this issue, many manufacturers use ultra-high pressure hoses to alleviate the conflict; one end of the ultrahigh pressure hose is connected with the pressure outlet of the adapter, and the other end of the ultrahigh pressure hose is connected with the pressure-bearing member. However, the pipe wall of the ultrahigh pressure hose is thicker, so that the problems that the bending radius of the pipe is too large, the circumferential rotation angle is almost zero and the like exist, the higher the pressure level is, the larger the bending radius is, and the bending radius of the ultrahigh pressure hose is more than 10 times of the outer diameter of the pipe generally, so that the miniaturization and integration progress of the ultrahigh pressure system are seriously affected.
And in normal pressure operation, the ultrahigh pressure hose connected with the pressure-bearing member needs to be manually removed, and after the spatial positions of the moving parts such as the end cover of the pressure-bearing member interface and the like are adjusted in place, the ultrahigh pressure hose is reconnected, so that the disassembly and the assembly are troublesome, and the operation is complex.

As shown in fig. 1, 2 and 4, the end cover 3 is fastened at the opening of the accommodating cavity 11 of the movable adapter 1, and the fixed adapter 2 passes through the end cover 3 and is partially arranged in the accommodating cavity 11. The fixed adapter 2 is cylindrical, one end of the fixed adapter is a pressure inlet 21 arranged outside the accommodating cavity 11, and the other end is a piston head 22 arranged in the accommodating cavity 11. The outer surface of the piston head 22 is provided with an annular groove 29, a sealing ring 26 is sleeved in the annular groove 29, the sealing ring 26 is tightly attached to the inner wall of the accommodating cavity 11, ultrahigh pressure sealing is realized, a pressure-bearing space is always reserved between the accommodating cavity 11 and the piston head 22, and in the embodiment, two sealing rings 26 are arranged. In order to prevent the seal ring 26 from being flushed out by the ultrahigh pressure medium, the fixed adapter 2 stretches and contracts in the accommodating cavity 11, and the moving path of the piston head 22 is between the first flow channel 13 and the end cover 2.
As shown in fig. 1, 2 and 4, the fixed adapter 2 is provided with a second flow passage 23 along the axial direction, and the second flow passage 23 communicates with the pressure inlet 21 and the accommodating cavity 11. The fixed adapter 2 is sleeved with a limit ring 4, and the limit ring 4 is positioned outside the end cover 3. Specifically, the outer wall of the fixed adapter, which is adjacent to the pressure inlet 21, is provided with a section of thread for threaded connection with a pipeline for fixing a pressure source.
