The outer peripheral wall of the elastic seal ring 50 is disposed in contact with the inner peripheral wall of the sleeve valve outer tube 10.

The two elastic sealing rings 50 can be respectively sleeved on the two fixing rings 22a, when the movable ring 30 is driven by the threaded rod 40 to move close to the fixing rings 22a, one end of the movable ring 30 is squeezed into the inner ring of the elastic sealing ring 50, so that the elastic sealing ring 50 expands outwards, and the squeezing force between the elastic sealing ring 50 and the inner wall of the sleeve valve outer tube 10 is increased; the two elastic sealing rings 50 may also be sleeved outside the grouting inner tube 20 and respectively located between the two fixing rings 22a and the two corresponding movable rings 30, so that when the movable rings 30 are driven by the threaded rod 40 to move toward the fixing rings 22a, the movable rings 30 and the fixing rings 22a directly extrude the elastic sealing rings 50, and the elastic sealing rings 50 also expand outward, so as to increase the extrusion force between the elastic sealing rings and the inner wall of the sleeve valve outer tube 10.

The sleeve valve outer pipe 10 is provided with a plurality of groups of slurry outlet holes 11 which are arranged at intervals, the slurry injection inner pipe 20 is provided with an input section 21 which is positioned outside the sleeve valve outer pipe 10 and a slurry injection section 22 which is inserted into the sleeve valve outer pipe 10, and the slurry injection section 22 is provided with a plurality of slurry injection holes 22b, so that the sleeve valve pipe slurry injector 100 can realize slurry injection. The two elastic sealing rings 50 are arranged at intervals on the grouting section 22, so that the sealing effect between the grouting section 22 between the two elastic sealing rings 50 and the sleeve valve outer tube 10 of the corresponding section is ensured, and the grout cannot flow up and down in series. Two fixing rings 22a are arranged at the upper end and the lower end of the grouting section 22 provided with the grouting hole 22 b; a movable ring 30 movably sleeved on the grouting section 22 and respectively arranged on one side of the two fixed rings 22a far away from the input section 21 is arranged; arranging a plurality of threaded rods 40, wherein each threaded rod 40 comprises a stop section 41 positioned on one side, opposite to the movable ring 30, of the fixed ring 22a adjacent to the input section 21 in the two fixed rings 22a and a threaded section 42 penetrating through the two fixed rings 22a and being in threaded connection with the two movable rings 30, so that the threaded rods 40 drive the two movable rings 30 to move towards or away from the corresponding fixed rings 22 a; when the movable ring 30 moves close to the fixed ring 22a, the elastic sealing ring 50 is squeezed to deform, and when the movable ring 30 moves away from the fixed ring 22a, the elastic sealing ring 50 returns to its original shape without being stressed, i.e., the abutting force between the elastic sealing ring 50 and the sleeve valve outer tube 10 can be controlled. Therefore, when the grouting is not performed, the movable ring 30 is controlled to be far away from the fixed ring 22a, so that the elastic sealing ring 50 is not deformed, and the abutting force of the elastic sealing ring and the inner wall of the sleeve valve outer tube 10 is small or not so that the grouting inner tube 20 can easily move up and down in the sleeve valve outer tube 10; on the contrary, the movable ring 30 is controlled to approach the fixed ring 22a during grouting, so that the elastic sealing ring 50 is deformed to increase the contact force against the inner wall of the sleeve valve outer tube 10, thereby improving the sealing performance between the elastic sealing ring 50 and the inner wall of the sleeve valve outer tube 10.
