(e.g., left and right sides in fig. 4). (the state shown by the solid line in fig. 9 is the locked state, and the broken line is the turning process |).
The front end of the telescopic tube head (3-6) is of a hemispherical smooth structure. (this allows a relatively smooth movement along the inner wall of the circular housing (3-1) even when the telescopic tube head (3-6) is pressed against the inner wall of the circular housing (3-1)
The rotary rod (3-12-2) is in dynamic seal with the contact position of the round shell (3-1), an end cover plate (3-1-6) of the round shell (3-1) for the rotary rod (3-12-2) to pass through is made of transparent material, so that the rotary position can be seen conveniently, in addition, a water outlet (3-1-7) with a plugging cover is arranged on the side surface of the bottom of the round shell (3-1), when water is possibly remained in the round shell (3-1) due to improper operation or after each operation, in order to prevent the excessive water from influencing the operation of the internal components, the water is discharged out through the water outlet (3-1-7) +! In addition, the inner walls of the through hole (3-1-1) and the sealing groove (3-1-2) are coated with soft sealing layers (3-1-8), and the periphery of the telescopic tube head (3-6) can be coated with sealing glue layers, for example, sealing glue pads and the like can be arranged, so that the sealing effect is enhanced.
A flange A for connecting a pipeline is arranged on the radial side wall (3-1-3) of the circular shell (3-1) at a position corresponding to the through hole (3-1-1), and is connected with the pipeline through the flange, so that the unilateral locking boiler pipeline cleaning and connecting device is connected with a wide-caliber rubber cover and an oil storage bottle, the flange connection belongs to the prior art, and is not repeated here-!
As shown in fig. 5-9, the flange on the left of the circular shell (3-1) is connected to the boiler pipeline through the pipeline, the flange on the right is connected to another pipeline, and then the positions of the first straight-through pipe (3-3), the second straight-through pipe (3-4) and the vertical pipe (3-5) are adjusted by twisting the rotary handle (3-12-3) through spinning, and the specific adjustment method is as follows: the state shown in fig. 5 is an initial state, in which the position of the stem (3-12-3) is the state shown in fig. 3, then the transverse stem (3-12-3) shown in fig. 3 is rotated counterclockwise, so that the driving gear (3-12) rotates relative to the central turntable (3-2), at the same time, the meshing rack (3-13) moves under the meshing of the driving gear (3-12) to pull the telescopic tube head (3-6) out of the through hole (3-1-1), at this time, the reset spring (3-14) is compressed, then the driving gear (3-12) is continuously rotated, so that the dial strip (3-12-1) contacts the dial rod (3-2-1) and moves against the dial rod (3-2-1), so that the central turntable (3-2) rotates together with the driving gear (3-12) (as shown in fig. 8), in which, if the cover plate (3-1-6) is made of transparent material, the rotational position can be observed, so that when rotating to the position shown in fig. 6, the restoring spring (3-12) is released, the stem (3-12) acts against the restoring spring (3-1) and the telescopic tube head (3-1) in the state (3-1) as shown in fig. 6), at this time, the vertical pipe (3-5) is closed, the first straight pipe (3-3) and the second straight pipe (3-4) form a straight pipe, and the pipe is communicated (the flow direction is shown by the arrow in fig. 6), at this time, because the inner walls of the through hole (3-1-1) and the sealing groove (3-1-2) are provided with the soft sealing layer (3-1-8), and the top force of the return spring (3-14) is added, the tight contact between the telescopic pipe head (3-6) and the soft sealing layer (3-1-8) is realized, or a sealing ring is sleeved at the middle part of the outer wall of the telescopic pipe head (3-6), so that the sealing can be realized by pushing, similar to the piston ring of an engine, the sealing mode, which belongs to the prior art and is not repeated here!

in addition, if the cover plate (3-1-6) is not made of transparent material during the rotation process, when the telescopic tube head (3-6) is about to rotate to the position of the next through hole (3-1-1), the telescopic tube head (3-6) can be pushed forward by loosening the rotary handle (3-12-3), if the position is not right, the rotary handle (3-12-3) is slowly screwed continuously when the inner wall is pushed, and then the telescopic tube head (3-6) is loosened again until the telescopic tube head (3-6) is pushed into the through hole (3-1-1) or the sealing groove (3-1-2), thus being not as visual as the transparent material, but being difficult to realize-! The transparent cover plate can be made of transparent and thickened acrylic plates or toughened glass, when the round shell (3-1) is assembled, an inner spigot is adopted at the opening of the round shell, then the periphery of the cover plate is punched, the cover plate is covered at the spigot (shown in figure 2), then the cover plate is fixed with the round shell (3-1) after penetrating through the holes at the periphery of the cover plate by using bolts L, then waterproof weather-proof sealant is sprayed at the contact position of the periphery of the cover plate and the round shell (3-1), and the same sealant is sprayed at the periphery of the bolts, so that the round shell is assembled, and the round shell is not repeated herein!
