Connecting rings 5 are fixedly arranged on both the upper and lower sides of the middle ring 4. Connecting grooves 6 matching the connecting rings 5 are formed on the side walls of the upper ring 2 and the lower ring 3 facing the middle ring 4. After the connecting rings 5 are inserted into the connecting grooves 6, the middle ring 4 is fixedly connected to the upper ring 2 and the lower ring 3. The outer sides of the middle ring 4, the upper ring 2 and the lower ring 3 are all arc-shaped structures. When the present utility model is used, a rubber adhesive is applied to the surface of the middle ring 4, and the connecting rings 5 are inserted into the connecting grooves 6 to contact and connect with the upper ring 2 and the lower ring 3, which plays a role in positioning and increasing the connection surface. At this time, the middle ring 4 is located between the upper ring 2 and the lower ring 3 and is fixedly connected to the upper ring 2 and the lower ring 3 through the rubber adhesive, completing the installation of the middle ring 4; a rubber adhesive is applied to the inner side of the outer sleeve 7, and the outer sleeve 7 is sleeved on the outer sides of the sealing sleeve 1, the middle ring 4, the upper ring 2 and the lower ring 3 and is fixedly connected to the sealing sleeve 1, the middle ring 4, the upper ring 2 and the lower ring 3 through the rubber adhesive, completing the installation of the outer sleeve 7; when the present utility model is used in a high-pressure environment, the upper ring 2 and the lower ring 3 are subjected to greater pressure, and the middle ring 4 is subjected to less pressure and is not easily broken. Even if the upper ring 2 and the lower ring 3 are broken, the middle ring 4 can still play a sealing role to prevent medium leakage; since the outer sides of the middle ring 4, the upper ring 2 and the lower ring 3 are all arc-shaped structures, the middle ring 4, the upper ring 2 and the lower ring 3 will push up the outer sleeve 7 to make it close to the outside, playing a role in enhancing the sealing performance; in summary, the present utility model has the beneficial effect of preventing medium leakage in a high-pressure environment, and solves the problems that the rubber sealing ring is in frequent contact with the outside and is subjected to pressure, is easy to age, and is easy to cause the rubber sealing ring to break, resulting in medium leakage.
[0020] Preferably, the outer ring assembly further includes an outer sleeve 7, and the outer sleeve 7 is sleeved on the outer sides of the sealing sleeve 1, the middle ring 4, the upper ring 2 and the lower ring 3 and is fixedly connected to the sealing sleeve 1, the middle ring 4, the upper ring 2 and the lower ring 3. Since the outer sleeve 7 is sleeved on the outer sides of the sealing sleeve 1, the middle ring 4, the upper ring 2 and the lower ring 3 and is fixedly connected to the sealing sleeve 1, the middle ring 4, the upper ring 2 and the lower ring 3, the outer sleeve 7 will replace the middle ring 4, the upper ring 2 and the lower ring 3 to contact the outside. During regular maintenance, only the outer sleeve 7 needs to be replaced.
[0021] Preferably, an anti - detachment ring 8 is fixedly arranged on one side of the connecting ring 5 facing the upper ring 2 and the lower ring 3.
