摘要（英）：

The invention discloses a sealing needle and belongs to the technical field of sealing needle design. The sealing needle comprises a slurry injecting hole, an injecting mouth, a hollow bolt and a sealed expansion sleeve. The injecting mouth is arranged at one end of the slurry injecting hole, the rod of the bolt is connected to the slurry injecting hole tightly in a screwed manner, the expansion sleeve sleeves the outer wall of the slurry injecting hole, the injecting mouth is provided with an one-way stop valve inside, and the slurry injecting hole is provided with an one-way sealing discharging hole inside. The sealing needle is characterized in that a sealing layer is arranged on the nut of the hollow bolt, and the sealing layer is provided with an one-way sealing port matching with the hollow position of the nut. The expansion sleeve is made of rubber material, and the sealing layer is made of rubber material. The sealing needle is reasonable and simple in structure and easy to produce and manufacture, the tight fitting of the sealing needle and a hole is guaranteed, and the quality and performance of slurry injection and leaking stoppage are improved effectively.
