[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1:

[0027] Please see Figs. 1-4 A tubular one-way sequence valve includes a one-way sequence valve body 1. Each port of the one-way sequence valve body 1 is fixedly connected to a support pipe 2. The end of the support pipe 2 away from the one-way sequence valve body 1 is fixedly connected to an assembly pipe 3. The top end of the support pipe 2 is fixedly connected to a transmission seat 4. One end of the transmission seat 4 is rotatably connected to a linkage shaft A5. One end of the inner wall of the transmission seat 4 is rotatably connected to a linkage shaft B6, and one end of the linkage shaft B6 passes through the linkage shaft A5. One end of the linkage shaft A5 and the linkage shaft B6 are both fixedly connected to a positioning clamp 7, which is used to position the medium pipeline. A transmission assembly 8 is provided on the transmission seat 4, which is used to drive the linkage shaft A5 and the linkage shaft B6 to rotate in opposite directions.

[0028] Among them, the one-way sequence valve body 1 is used for one-way free flow or restricted flow. The valve action depends on the state of the control signal. It controls the fluid by using a high-speed switch of a transistor, a hydraulic switch inside the valve seat, and a piston or diaphragm to separate the two joints. This is a mature existing technology and will not be described in detail here.

[0029] In detail, the diameter of the assembly pipe 3 is smaller than that of the support pipe 2, and a sealing ring is fixedly connected to the outside of the assembly pipe 3. Through the change in diameter between the assembly pipe 3 and the support pipe 2, after the medium pipeline is fitted onto the assembly pipe 3, the outer diameter of the medium pipeline can be the same as the outer diameter of the support pipe 2.

[0030] Here, the linkage shaft A5 has a hollow structure, and the inner wall of the linkage shaft A5 is provided with multiple alloy balls, which are in contact with the linkage shaft B6. By utilizing the structural characteristics of the linkage shaft A5, the linkage shaft B6 can smoothly move along the linkage shaft A5. In addition, the alloy balls greatly improve the rotational stability of the linkage shaft B6.

[0031] In detail, the cross-sectional shape of the positioning clip 7 is semi-circular. By utilizing the structural cooperation of the positioning clip 7, when two positioning clips 7 are spliced ​​together, a complete circle can be formed, thereby achieving effective clamping of the medium pipeline.

[0032] The transmission assembly 8 includes a transmission shaft 9, a transmission bevel gear 10, and a matching bevel gear 11. The transmission shaft 9 is rotatably connected to the middle of the top of the transmission seat 4. The transmission bevel gear 10 is fixedly connected to the bottom of the transmission shaft 9. The matching bevel gear 11 is fixedly connected to the other ends of the linkage shaft A5 and the linkage shaft B6, and the two matching bevel gears 11 are respectively meshed with the two ends of the transmission bevel gear 10. The anti-rotation chuck 12 is fixedly connected to the top of the outer side of the transmission shaft 9, and the stabilizing frame 13 is fixedly connected to the top of the transmission seat 4.

[0033] Furthermore, the outer side of the anti-rotation chuck 12 is provided with multiple locking slots, and the anti-rotation chuck 15 is engaged and connected inside the locking slots. By utilizing the locking slots, when the anti-rotation chuck 15 is connected to the anti-rotation chuck 12, the anti-rotation chuck 15 can be engaged inside the locking slots, thereby ensuring the application effect of the anti-rotation chuck 15.

[0034] The transmission assembly 8 also includes a stabilizing shaft 14, an anti-rotation clamp 15, and a force-bearing rod 16. The stabilizing shaft 14 is rotatably connected to the bottom of the inner side of the stabilizing frame 13. The anti-rotation clamp 15 is fixedly connected to the middle of the stabilizing shaft 14, and the anti-rotation clamp 15 is engaged with the anti-rotation chuck 12. The force-bearing rod 16 is fixedly connected to one side of the bottom of the anti-rotation clamp 15. The end of the force-bearing rod 16 away from the anti-rotation clamp 15 is fixedly connected to a mounting rod A17. The mounting rod B18 is fixedly connected to the inner wall of the stabilizing frame 13, and a tension spring 19 is assembled between the mounting rod A17 and the mounting rod B18.

[0035] Here, the force-bearing rod 16 is fixedly connected to the bottom end of the anti-rotation clamp rod 15 at an angle, and the outer side of the force-bearing rod 16 is provided with anti-slip texture. The angled setting of the force-bearing rod 16 makes it easier for personnel to press the force-bearing rod 16, and the anti-slip texture can prevent personnel's hands from slipping.

[0036] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0037] Working principle: First, the external medium pipeline is fitted onto the outside of the assembly tube 3. Then, the downward-fixed force rod 16 is installed. With the connection between the force rod 16 and the anti-rotation clamp 15, the force rod 16 can rotate under the support of the anti-rotation clamp 15, and at the same time, the force spring 19 is stretched until the force rod 16 disengages from the anti-rotation chuck 12, thereby unlocking the transmission shaft 9. Then, rotating the transmission shaft 9 causes the transmission bevel gear 10 to simultaneously move the two matching bevel gears 11, thereby simultaneously driving the linkage shaft A5 and linkage shaft B6 to rotate in opposite directions until the two positioning clamps 7 are engaged, clamping the medium pipeline on the outside of the assembly tube 3. This achieves rapid assembly of the medium pipeline and effectively reduces the assembly time.
