As shown in fig. 1, 2 and 6, when the airflow passes through the air guide channel 103, the airflow pushes the blades 62, so that the knot ring 6 tends to rotate, after the inner layer of the blocking material on the knot fins 61 of the knot ring 6 and the blocking material in the middle are separated, the blocking material on the knot ring 6 rotates along with the knot ring 6, if the resistance is not great, the blocking material can rotate along with the knot ring 6, after the knot ring 6 rotates, the material attached to the knot ring collides with the knot rods 111, wherein the knot rods 111 are small protrusions, and because the density of the upper part of the blocking material is low, the upper part is firstly crushed and broken in the rotating process, so that the whole is uneven, the blocking material is continuously rolled and collided until the passing crushing degree is reached, and when the blocking material rotates at the knot ring 6, the blocking material is contacted with the blocking block on the right side, so that the crushing effect is increased.
Specifically, the radial included angle of the first gas injection holes 104 and the second gas injection holes 105 in the vertical direction of the conveying pipeline 1 is smaller than zero.
The air injection directions of the first air injection holes 104 and the second air injection holes 105 are opposite to the rotation direction of the knot ring 6, namely, when the knot ring 6 rotates, a larger tearing force is generated between the blocking material and the blowing force of the air flow, so that the material is crushed.
Specifically, the communicating member includes a first node connecting chamber 41, a connecting pipe 42, and a second node connecting chamber 43, the first node connecting chamber 41 and the second node connecting chamber 43 communicate with each other through the connecting pipe 42, the first node connecting chamber 41 communicates with the piston case 5 when the movable plug 3 is in the first state, and the first node connecting chamber 41 and the second node connecting chamber 43 communicate with the first connecting passage 302 and the second connecting passage 303, respectively, when the movable plug 3 is in the second state.
The first node connecting chamber 41 has two communication grooves (not shown), one of which communicates with the connecting pipe 42, and when the first connecting passage 302 moves to the groove, the first connecting passage 302 directly communicates with the connecting pipe 42, and the other of which has a long length and communicates with the piston case 5, and when the first connecting passage 302 communicates with the groove, the first connecting passage 302 directly communicates with the piston case 5.

Through threaded connection between sealing plate 22 and pressure cylinder 2, can change when rotating sealing plate 22 and the relative position between pressure cylinder 2, and then can change the pressure of spring 23 for movable stopper 3, can change the action pressure value, because during partly putty, movable stopper 3 only receives the pressure of spring 23, consequently utilizes spacing ring 21 to carry out spacingly.
The working principle is as follows: as shown in fig. 1, the conveying pipeline 1 is a pipeline for conveying fluid, especially for conveying gas or liquid with particulate matter, wherein the valve 11 is a valve in the pipeline, when the valve 11 is closed, the particulate matter in the fluid is accumulated on the right side of the valve 11 to gradually fill the space on the right side of the valve 11, at this time, the pressure at the pressure detecting hole 101 is gradually reduced, the air inlet chamber 201 is far away from the blockage and is located at the upper part of the conveying pipeline 1, the blockage is not easy to occur, the pressure at the air inlet chamber 201 is higher, therefore, the pressure at the right end of the movable plug 3 is higher than the pressure at the left end detecting chamber 202, when the pressure difference is higher than a certain value, the pressure of the spring 23 can be adjusted by rotating the sealing plate 22 to adjust the differential pressure action value of the detecting chamber 202 and the air inlet chamber 201, when the movable plug 3 is in the first state, i.e. when the pressure on, the first connecting channel 302 is communicated with the piston box 5, so that pressure is applied to the piston 53 to keep the piston 53 unable to move downwards, the space in the pipeline is relatively small, when the pressure on the right side of the movable plug 3 and the pressure difference on the left side reach an action value, the movable plug 3 is in a second state, as shown in fig. 4, at this time, the first connecting channel 302 is communicated with the hollow pipe 51, and the first connecting channel 302 is communicated with the second connecting channel 303 through the first node connecting chamber 41, the connecting pipe 42 and the second node connecting chamber 43, the gas entering the hollow pipe 51 pushes the guide pillar 52 downwards to make the piston 53 move downwards in the piston box 5, and due to the high pressure above the guide pillar 52, the air below the piston 53 is compressed until an equilibrium state is reached, so that a piece of space is added at the piston 53, so that the surrounding materials can be gathered therein, collapsed and the blockage original structure is broken, at this moment, the fluid entering the air guide hole 102 is ejected through the air guide channel 103, the first air injection hole 104 and the second air injection hole 105, the blockage with an unstable structure on the right side is impacted again, the blockage is further crushed towards the direction of the valve 11, meanwhile, the fluid passing through the air guide channel 103 is contacted with the blades 62 on the knot ring 6, the knot ring 6 rotates, the blockage can be gathered on the knot fins 61 on the inner wall of the knot ring 6, when the knot ring 6 rotates due to the blowing of the fluid, the condensed blockage is driven to rotate together, and meanwhile, the blockage collides with the knot rod 111, so that the blockage on the right side of the valve 11 is gradually crushed, and the dredging purpose is achieved.
