Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0029] Example:

[0030] See also Figure 1-7 The sealing motor fixing flange includes a motor body 1, a sealing flange 3 is fixed on the top of the motor body 1, a fixing flange 2 is provided on the top of the sealing flange 3, a detachable circular connecting ring 4 is provided on the outside of the fixing flange 2 and the sealing flange 3, a top conical groove 21 is provided on the top of the inside of the fixing flange 2, and a plurality of threaded through holes 22 are evenly distributed inside the fixing flange 2;

[0031] A plurality of transverse fixing columns 5 are evenly distributed and fixed at the top and bottom ends of the circular connecting ring 4. The internal threads of the transverse fixing columns 5 are connected to transverse threaded bolts 6. Transverse threaded holes are evenly distributed inside the fixed flange 2 and the sealing flange 3 and are provided with transverse threaded bolts 6. Through the provision of the transverse threaded holes, the circular connecting ring 4 can be located on the outside of the fixed flange 2 and the sealing flange 3, thereby enabling the fixed flange 2 and the sealing flange 3 to be fixed to prevent the fixed flange 2 and the sealing flange 3 from falling off.

[0032] An annular cone block 31 is fixed to one end of the top of the sealing flange 3, and a conical sealing gasket 32 is provided on the top of the annular cone block 31. A bottom conical groove 24 adapted to the annular cone block 31 is opened at the bottom of the fixed flange 2. The arrangement of the bottom conical groove 24 and the annular cone block 31 enables a better connection between the fixed flange 2 and the sealing flange 3. The arrangement of the conical sealing gasket 32 can improve the sealing performance between the fixed flange 2 and the motor body 1.

[0033] An annular T-block 35 is fixed inside the sealing flange 3, and a U-shaped sealing block 33 is fixed on the top of the annular T-block 35. The U-shaped sealing block 33 is located outside the bottom of the threaded through hole 22. A vertical groove adapted to the U-shaped sealing block 33 is opened inside the fixed flange 2. The vertical groove allows the U-shaped sealing block 33 to be installed inside the fixed flange 2.

[0034] Annular dovetail blocks 34 are fixed at both ends of the U-shaped sealing block 33. An annular dovetail groove adapted to the annular dovetail block 34 is opened inside the fixed flange 2, thereby improving the sealing performance of the U-shaped sealing block 33 on the bottom of the threaded through hole 22, improving the connection strength between the fixed flange 2 and the sealing flange 3, and preventing the U-shaped sealing block 33 from falling off inside the fixed flange 2.

[0035] A vertical sealing ring 23 is fixed to the bottom of the threaded through hole 22 and at one end away from the bottom tapered groove 24. A vertical annular groove adapted to the vertical sealing ring 23 is formed on the top of the sealing flange 3. The arrangement of the vertical sealing ring 23 and the vertical annular groove can improve the lateral sealing performance of the fixed flange 2.

[0036] A lateral sealing ring 36 is further provided at the other end of the top of the sealing flange 3. A lateral annular groove adapted to the lateral sealing ring 36 is provided inside the threaded through hole 22.

At this time, the annular cone block 31 fits with the bottom conical groove 24. The provision of the conical sealing gasket 32 can improve the sealing performance between the bottom conical groove 24 and the annular cone block 31. At the same time, the provision of the vertical sealing ring 23 and the lateral sealing ring 36 can improve the side sealing performance between the fixed flange 2 and the sealing flange 3, and prevent gas leakage. The provision of the U-shaped sealing block 33 can seal the bottom of the threaded through hole 22 to prevent gas leakage from the bottom of the threaded through hole 22.

[0038] By placing the sealing flange 3 between the fixed flange 2 and the motor body 1 and sealing it at the bottom of the threaded through hole 22, gas leakage through the threaded through hole 22 can be effectively prevented, solving the problem of flange leakage. The close contact between the fixed flange 2 and the sealing flange 3 can improve the sealing performance of the fixed flange 2 and the sealing flange 3. Even during long-term use, the sealing performance of the sealing flange 3 can still remain stable.

[0039] During use: the sealing flange 3 is welded to the motor body 1, the fixed flange 2 is docked with the sealing flange 3, and then the circular connecting ring 4 is sleeved on the outside of the fixed flange 2 and the sealing flange 3. By rotating the transverse threaded bolt 6 into the inside of the transverse fixing column 5, the fixed flange 2 and the circular connecting ring 4, as well as the sealing flange 3 and the circular connecting ring 4, can be better fixed;

[0040] At this time, the annular cone block 31 fits with the bottom conical groove 24. The setting of the conical sealing gasket 32 can improve the sealing performance between the bottom conical groove 24 and the annular cone block 31. At the same time, the setting of the vertical sealing ring 23 and the lateral sealing ring 36 can improve the side sealing performance between the fixed flange 2 and the sealing flange 3, and prevent gas leakage. Through the setting of the U-shaped sealing block 33, the bottom of the threaded through hole 22 can be sealed to prevent gas from leaking from the bottom of the threaded through hole 22.
