[0043] In detail, the top of the liquid inlet pipe 2 and the liquid outlet pipe 3 are both provided with an avoidance notch 41, and a sealing sheet 42 is connected to the linkage bar 40 by screws. By setting the avoidance notch 41, the stabilizing plate 30 and the assembly shell 32 can be moved into the liquid inlet pipe 2 or the liquid outlet pipe 3, and after cleaning, the stabilizing plate 30 and the assembly shell 32 can be moved out of the liquid inlet pipe 2 or the liquid outlet pipe 3 to avoid occupying the internal space of the liquid inlet pipe 2 or the liquid outlet pipe 3;

[0047] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0048] Working principle: First, turn the adjusting column 20, and cooperate with the connection between the adjusting column 20 and the guide screw 21, so that the guide screw 21 can drive the locking plate 23 to move linearly under the limit of the limit plate 22, until the locking plate 23 is connected with the matching lock plate 26. When the two locking plates 23 are respectively connected with the two matching lock plates 26, turn any one of the transmission shafts 17, and the two transmission shafts 17 can be driven to rotate at the same time under the linkage of the linkage shaft 25, so that the transmission worm 18 drives the matching worm wheel 19, and then drives the guide shaft 12 to rotate, and because the transmission The worm 18 is located between the two worm gears 19, so that the two guide plates 13 rotate in opposite directions. Under the connection between the guide column 14 and the linkage groove 16, the two quick-release clamps 7 can be pulled close to each other, and then the external medium pipeline is sleeved on the outside of the liquid inlet pipe 2 and the liquid outlet pipe 3. Then, the two quick-release clamps 7 are assembled together by rotating the transmission shaft 17, so that the medium pipeline can be quickly assembled. When a certain medium pipeline is subsequently disassembled, the locking plate 23 and the matching lock plate 26 can be separated to release the linkage between the two transmission shafts 17.

[0049] In addition, the setting of the impurity barrier 9 can block impurities and particles in the water flow, prevent impurities and particles from entering the hydraulic valve body 1, and cause blockage inside the hydraulic valve body 1. When the impurity barrier 9 is not effective, the sealing sheet 42 is first removed to expose the avoidance gap 41, and the adjusting screw 28 is rotated, and the connection between the adjusting screw 28 and the adjusting frame 29 is coordinated, so that the adjusting frame 29 can be displaced along the adjusting screw 28, and the assembly housing 32 is moved into the liquid inlet pipe 2 or the liquid outlet pipe 3, and then the driving shaft 31 is rotated to drive the transmission bevel gear 3 6. The linkage bevel gear 37 is turned to transmit the power at the driving shaft 31 to the cleaning shaft 33, so that the cleaning shaft 33 drives the guide rod 34 to rotate, and the cleaning plate 35 scrapes the impurity-blocking net 9 to scrape off the impurities and particles on the impurity-blocking net 9. In addition, in conjunction with the connection between the driving shaft 31 and the guide sheet 38, when the driving shaft 31 drives the guide sheet 38 to rotate, the linkage bar 40 can push the guide ring 39 to drive the guide rod 34 to move back and forth, so that the cleaning plate 35 knocks the impurity-blocking net 9 to knock off the impurities and particles on the impurity-blocking net 9.
