One end of the steel sleeve 1 is fixedly connected with a circular bottom plate 5, and the outer diameter of the bottom plate 5 is equal to that of the steel sleeve 1; the graphite packing 3 is abutted with the bottom plate 5.
As shown in fig. 2 and 3, the steel sleeve lug plate 6 is annular, and the inner circle of the steel sleeve lug plate 6 is fixedly connected with one end of the steel sleeve 1 far away from the bottom plate 5. The steel sleeve lug plate 6 is provided with a plurality of evenly distributed sinking cavities, and fixing holes 7 are formed in the sinking cavities. And pressure supplementing holes 8 are further formed between two adjacent sinking cavities on the steel sleeve lug plate 6.
As shown in fig. 4, a gland 2 is further arranged at one end, far away from the bottom plate 5, of the steel sleeve 1, and one end of the gland 2 is abutted with the graphite packing 3. An annular gland lug plate 10 is fixedly connected to one end, which is far away from the outer side of the gland 2 and is abutted against the graphite packing 3; the gland lug plate 10 is provided with a connecting hole 9 at a position corresponding to the pressure supplementing hole 8.
