The second step is that: two external member mechanisms 1 connect through coupling mechanism 2 around to when two external member mechanisms 1 connect the pipeline end of two docks respectively, still can regard as a whole between the device, thereby coupling mechanism 2's spiral coil design provides convenience for the nimble connection of external member mechanism 1, in addition in strorage device, through coupling mechanism 2 external member mechanism 1 that connects in pairs also can be convenient for to accomodating and categorizing of device.
The third step: the end of the pipeline is connected in a wrapping mode through the external mechanism 1, the external mechanism 1 is connected in a fully-wrapping mode through the external mechanism 4 from the outer side, so that when a high-temperature high-pressure medium inside the pipeline influences the pipeline, the external mechanism 4 which is externally fastened cannot be directly acted on, but the external mechanism 1 and other components act on, so that in the state of high pressure and high temperature, the internal components expand under the influence of high temperature and high pressure, not only is the expansion and extrusion of the connecting mechanism 2 per se more tight, but also the fastening effect of the external mechanism 4 on the internal components is enhanced due to the expansion of the internal components, the loosening influence of the high temperature and high pressure on the external mechanism 4 is offset, the durability of the device is improved, and the service life of the device is prolonged.
The fourth step: communicate the pipeline through external member mechanism 1, the connection edge that originally reveals easily is separated into the line of spiral by coupling mechanism 2 this moment, the gomphosis of both sides lantern ring 104 around in addition separates into annular square route with coupling mechanism 2's outside flow direction again, wrap up fastening belt 401 from the outside at last and further seal, thereby to the medium of pipeline inside, the distance of revealing required circulation is compared in original triple, the passageway of revealing has further been sealed off in the extrusion between the part in addition, thereby make the device can effectively and the efficient completion sealed.
The fifth step: through the connection of the external member mechanism 1 and the connection mechanism 2, the actual internal diameter of a part of existing pipelines of the device is reduced compared with the surrounding internal diameter, at this time, through the design of the winding roller 301, the medium flowing from the pipeline into the device can drive the flow fan 303 to rotate, meanwhile, the medium backflow effect generated due to the reduction of the internal diameter of the external member mechanism 1 can also wind back from the flow fan 303 to accelerate the rotation of the flow fan 303, and meanwhile, the rotation of the flow fan 303 can also guide the rotation of the flow fan 303 to drive the rotation of the winding roller 301, so that the pulling rope 305 is contracted, at this time, the spiral belt 306 can be elongated and rubbed along the inner walls of the external member mechanism 1 and the connection mechanism 2, so that in the switching process of flowing and static states, the spiral belt 306 can be stretched and contracted, so as to rub the internal parts of the external member mechanism 1 and the connection mechanism 2, thereby removing the impurities left and the internal walls of the external member mechanism 1 and the connection mechanism 2 and enabling the impurities to move synchronously along the medium, thereby avoiding the further reduction of the internal diameter, affecting the circulation of the pipeline, and improving the cleaning effect of the device.
And a sixth step: through the design of half dismouting of device to when overhauing the pipeline, only need dismantle the external mechanism 4 in the outside can overhaul and handle the external member mechanism 1 and the 2 parts of coupling mechanism of inside, overhaul the back that finishes, directly install external mechanism 4 can, need not to dismantle the whole dismantlements of the part of connecting, improve the maintenance and the dismouting efficiency of device.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
