[0008] Preferably, the connector includes a stud and a nut. Fixed seats one are provided at both ends of the clamping one, and fixed seats two are provided at both ends of the clamping two. Grooves are provided on the fixed seats one and the fixed seats two. One end of the stud is rotatably arranged in the groove of the fixed seat one through a shaft, the other end of the stud is clamped into the groove of the fixed seat two, and the nut is threadedly connected to the stud and presses against the fixed seat two.

[0009] Preferably, the sealing gasket is set as a semi-annular structure. When in use, the edge of the sealing gasket is pressed between two flanges.

[0010] The utility model adopts the above structure and obtains the following beneficial effects: The clamping one and the clamping two are sleeved around two flanges, the sealing gasket is pressed between two flanges, the connector fixes the clamping one and the clamping two, and the waterproof gaskets can enhance the sealing effect of two flanges.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0016] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present utility model. In addition, the terms "first", "second", and "third" are only used for descriptive purposes and should not be construed as indicating or implying relative importance. The present utility model will be further described in detail below with reference to the accompanying drawings.

[0017] Such as Figures 1-3As shown in the figure, a flange sealing device for preventing leakage proposed by the present utility model includes a first clamp 1, a second clamp 2, and a sealing gasket 3. The cross-sections of the first clamp 1 and the second clamp 2 are both set as U-shaped structures, and the first clamp 1 and the second clamp 2 are both set as semi-circular structures. When in use, the first clamp 1 and the second clamp 2 are sleeved on the edges of the two flanges. Embedded grooves 4 are provided on the inner side walls of the first clamp 1 and the second clamp 2. The ends of the sealing gasket 3 are clamped into the embedded grooves 4. The sealing gasket 3 is set as a semi-circular ring structure. When in use, the edges of the sealing gasket 3 are pressed tightly between the two flanges. Connectors 5 are provided at the ends of the first clamp 1 and the second clamp 2 to sleeve the first clamp 1 and the second clamp 2 around the two flanges, the sealing gasket 3 is pressed between the two flanges, and the connectors 5 fix the first clamp 1 and the second clamp 2.

[0018] As Figure 3 shown, waterproof gaskets 6 are provided on the inner side walls of the first clamp 1 and the second clamp 2. The waterproof gaskets 6 are respectively located on the upper and lower sides of the sealing gasket 3, and the first clamp 1 and the second clamp 2 are further clamped tightly on the side walls of the two flanges through the waterproof gaskets.
