At the same time, the liquid destination channel is also increased, and there is no need to transport a pipeline to multiple places for operation.

[0036] Working principle:

[0037] When in use, a hose is installed on the quick-connect installation pipe 15, and the hose is fixed to the quick-connect installation pipe 15 by a clamp. This has been prepared before the operation, and after the operation, the hose and the quick-connect installation pipe 15 do not need to be disassembled, and can be directly rolled up, which is convenient for the quick connection between the quick-connect installation pipe 15 and the high-pressure pump body 2 at a later time;

[0038] During the operation and installation, the inlet and outlet of the high-pressure pump body 2 are installed in the same way. First, the movable installation rod 24 is pulled by the end connection round block 25, and the positioning connection protruding rod 26 slides along the movable through straight groove 32. The connection spring 21 is in a stretched state, and the movable installation rod 24 moves with the movable connection straight plate 27, and finally the two tightly connected straight rods 29 are made to come out from the inside of the pipe fixed end 12. During the movement of the movable connection straight plate 27, the second fixed outer rod 31 is provided to cooperate with the second movable inner rod, so that the two tightly connected straight rods 29 can move in a straight line, and then the quick-connect installation pipe 15 with the end positioning plate body 16 is put into the inside of the pipe fixed end 12, so that the end positioning plate body 16 is in conflict with the sealing annular gasket 14;

[0039] Then, the end connection round block 25 is first loosened, and the two tightly connected straight rods 29 are allowed to enter the interior of the pipe fixed end 12 through the reset effect of the connection spring 21, and then the end connection round block 25 is pressed again, so that the two tightly connected straight rods 29 are against the end positioning plate body 16, and the end positioning plate body 16 is fixed. At this time, the positioning connection protruding rod 26 also moves to the end of the movable through straight groove 32 and is located at the position of the limited through groove body 33, and the end connection round block 25 is rotated. The end connection round block 25 rotates with the movable installation pull rod 24, and the movable installation pull rod 24 rotates with the positioning connection protruding rod 26, so that the positioning connection protruding rod 26 is stuck in the interior of the limited through groove body 33. After loosening the end connection round block 25, the movable installation pull rod 24 does not move. At this time, the connection spring 21 is in a compressed state, and the pipe connection is completed.

[0040] By opening the corresponding connecting valve 13, a liquid passage can be formed. The liquid enters the annular fixed pipe 10 through the branch installation pipe 11 at the inlet, and then enters the circular hollow shell 8 through the fixed installation branch pipe 9, and then enters the fixed installation main pipe 7 through the circular hollow shell 8, and then enters the fixed installation main pipe 7 at the outlet of the high-pressure pump body 2, and finally enters the branch installation pipe 11 on the outlet side, and is discharged through the hose on the outlet side.

Even if one source pipeline is damaged, the corresponding connecting valve 13 can be closed, and the pipeline can still continue to work. At the same time, the liquid destination channel is also increased, and there is no need to transport a pipeline to multiple locations for operation;
