Working principle:

the first step: the outer package plate 102 is located the outside of pipeline and thereby presss from both sides tight pipeline through lantern ring 104 thread tightening, thereby external sleeve joint is in the pipeline end of required connection in external sleeve mechanism 1 back, through rotating swivel 109, thereby make adjusting tank two 112 and adjusting tank one 108 just change the position just, spacing through stopper 117 and spacing groove 113, thereby make the groove post 116 along adjusting tank one 108 and adjusting tank two 112 to the position that keeps away from fishplate bar 101 center progressive removal, make the laminating of adaptability according to the different wall thicknesses of pipeline, the protruding ball 110 is connected further firm external sleeve mechanism 1 to the inside and outside centre gripping with the pipeline with the embedding of inside groove 107 simultaneously, make the pipeline of multiple model of device adaptation, improve the application scope of device.

And a second step of: the front and back external member mechanisms 1 are connected through the connecting mechanism 2, so that when the two external member mechanisms 1 are respectively connected with two butted pipeline ends, the two external member mechanisms can still be used as a whole, the spiral winding design of the connecting mechanism 2 provides convenience for flexible connection of the external member mechanisms 1, and in addition, when the device is stored, the external member mechanisms 1 connected in pairs through the connecting mechanism 2 can also be used for conveniently storing and classifying the device.

And a third step of: the end of the pipeline is connected in a wrapping mode through the sleeve mechanism 1, the sleeve mechanism 1 is connected in a full-surrounding mode through the external connection mechanism 4 from the outside, so that high-temperature and high-pressure mediums inside the pipeline are influenced, and meanwhile, the external connection mechanism 4 is not directly acted on components fastened outside, but acts on the sleeve mechanism 1 and the like, under the high-temperature and high-temperature state, the internal components are expanded due to the influence of high-temperature and high-pressure, the expansion and extrusion of the connecting mechanism 2 are tighter, meanwhile, the fastening effect of the external connection mechanism 4 on the internal components is enhanced due to the expansion of the internal components, and therefore the loosening influence of the high-temperature and high-pressure on the external connection mechanism 4 is counteracted, the durability of the device is improved, and the service life of the device is prolonged.

Fourth step: the pipeline is communicated through the external member mechanism 1, the connecting edge which is easy to leak originally is separated into spiral lines by the connecting mechanism 2, the embedding of the lantern rings 104 at the front side and the rear side separates the outside flow direction of the connecting mechanism 2 into annular square lines, and finally the lantern rings 104 are wrapped with the fastening belt 401 from the outside to seal further, so that the path for the medium inside the pipeline to leak is three times longer than the original path, the leaking path is further blocked by extrusion between the parts, and the device can be sealed effectively and efficiently.

Fifth step: through the connection of external member mechanism 1 and coupling mechanism 2 to make the partial actual pipeline internal diameter that the device exists reduce than the internal diameter on every side, this moment through the design around roller 301, the medium that gets into the device from the pipeline can drive the flow fan 303 rotation, thereby simultaneously because the medium backward flow effect that external member mechanism 1 internal diameter reduces also can follow the rotation of flow fan 303 round back to accelerate flow fan 303, simultaneously the rotation of flow fan 303 also can guide the rotation that is close to flow fan 303 can drive the rotation around roller 301, thereby shrink stay cord 305, spiral belt 306 can be elongated at this moment, and cut and scratch along external member mechanism 1 and coupling mechanism 2's inner wall, so in the switching process of circulation and stationary two kinds of states, spiral belt 306 can stretch and shrink, thereby cut and scratch the inside part of external member mechanism 1 and coupling mechanism 2, thereby clear away the impurity that remains and external member mechanism 1 and coupling mechanism 2 inner wall, make it follow the medium and move synchronously, avoid the internal diameter to remain because impurity to influence the circulation of pipeline, improve the clearance effect of device.

Sixth step: through the semi-disassembly design of the device, when the pipeline is overhauled, the external mechanism 4 on the outer side only needs to be disassembled to overhaul and treat the internal external mechanism 1 and the connecting mechanism 2, after the overhaul is finished, the external mechanism 4 is directly installed, all the connected components do not need to be disassembled, and the overhaul and disassembly efficiency of the device is improved.

Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
