[0036] Please refer to Figures 3 to 5 , A movable sealing assembly for movably extending and docking with the intake pipeline is provided on the connecting inner pipe 5. The movable sealing assembly includes an outer pipe 8.

[0037] The lower surface of the outer pipe 8 is communicated with a flange plate 9. A plurality of equally spaced flange holes are provided on the flange plate 9, which is convenient for connecting and fixing with the connecting pipeline through fastening screws passing through the flange holes.

[0038] It should be noted that the movable sealing assembly further includes an annular seat 6 that is communicated with the bottom of the connecting inner pipe 5 and fits against the inner wall of the outer pipe 8. A plurality of annularly and equally spaced telescopic rods 7 are fixedly installed between the annular seat 6 and the inner wall of the outer pipe 8. An annular sealing groove one 10 concentric with the annular seat 6 and in the shape of a circle is formed on the upper surface of the annular seat 6. An annular sealing ring one 11 that closely fits against the outer wall of the connecting inner pipe 5 and the inner wall of the annular seat 6 is placed in the annular sealing groove one 10.

[0039] Among them, the diameter of the annular seat 6 is equal to the inner diameter of the outer pipe 8.

[0040] The telescopic rod 7 is composed of an outer cylinder and an inner rod that slide connected to each other. The outer cylinder and the inner rod are not separated from each other. The ends of the outer cylinder and the inner rod away from each other are respectively connected to the annular seat 6 and the outer pipe 8.

[0041] A regulating and sealing assembly for sealing the gap between the connecting inner pipe 5 and the outer pipe 8 through adjustment is provided between the connecting inner pipe 5 and the outer pipe 8 in this embodiment.

[0042] It should be noted that the regulating and sealing assembly includes an extrusion sealing member and a regulating extrusion member.

[0043] The extrusion sealing member

[0044] It includes a second annular sealing groove 12 which is circular ring-shaped and concentric with the first annular sealing ring 11 and is opened on the upper surface of the first annular sealing ring 11. An second annular sealing ring 13 is placed in the second annular sealing groove 12. A rigid annular seat 14 is fixedly installed on the upper surface of the second annular sealing ring 13.

[0051] The working principle of the above embodiment is as follows:

[0052] After the valve body 1 is connected to the soot blower, according to the distance between the flange 9 and the connecting pipe, pull the outer pipe 8 downward to drive the telescopic hose 15 on the closed annular seat 16 to contract synchronously. At this time, the telescopic rod 7 extends synchronously, so that the flange 9 moves to be butted against the connecting pipe, thereby facilitating the adjustment of the telescopic and butt joint installation with the connecting pipe, improving the convenience of installation, and avoiding the phenomenon that there is a large distance between the flange 9 and the pipe after the valve body 1 is installed and positioned, resulting in difficult installation operation.

[0053] After installation, by rotating the set rotating rod 21 to drive the adjusting nut 18 to screw into the threaded sleeve 17, while the adjusting nut 18 moves downward to push the hard annular seat 14 and the second annular sealing ring 13 on the connecting rod 20 to closely fit in the second annular sealing groove 12 to form a seal with the first annular sealing ring 11, so as to realize that the annular seat 6, the closed annular seat 16, the telescopic hose 15, the hard annular seat 14, and the second annular sealing ring 13 form a sealing system. At the same time, during the downward movement of the second annular sealing ring 13, the first annular sealing ring 11 is extruded, causing the first annular sealing ring 11 to deform and closely fit the outer tube 8 to further seal the gap between the outer tube 8 and the annular seat 6. Thus, while realizing the adjustment and docking to improve the installation convenience, the sealing performance after adjustment is ensured.
