[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0023] The embodiments of this utility model will be described below based on its overall structure.

[0024] A sealing device for a high-temperature oil pump, such as Figures 1-5 As shown, the system includes a first flange 1 and a second flange 2. An oil pipe 8 is fixedly connected to one side of the first flange 1, and a high-temperature oil pump 10 is fixedly connected to one side of the second flange 2. An air bladder 3 is disposed between the first flange 1 and the second flange 2. The first flange 1 and the second flange 2 are movably connected by multiple sets of bolts 6 and nuts 7. The oil inlet and outlet pipes of the high-temperature oil pump 10 are both installed using a structure in which an air bladder 3 is disposed between the first flange 1 and the second flange 2. When the liquid in the high-temperature oil pump passes through the air bladder 3, the liquid compresses the air bladder 3. At the same time, the hydraulic oil disposed inside the air bladder 3 compresses the other edges of the air bladder 3, thereby making the air bladder 3 fit tightly against the groove 5, thereby further improving the sealing effect.

A cavity 4 is provided inside the airbag 3, and hydraulic oil is provided inside the cavity 4. When the liquid in the high-temperature oil pump passes through the airbag 3, the liquid squeezes the airbag 3. At the same time, the hydraulic oil inside the airbag 3 squeezes the other edges of the airbag 3, so that the airbag 3 fits tightly with the groove 5, thereby further improving the sealing effect. At the same time, under the compression of the hydraulic oil, the airbag 3 squeezes and fixes multiple bolts 6, thereby further tightening the bolts.

[0027] The working principle of the utility model is as follows: in use, the user places the air bag 3 on the surface of the second flange plate 2, further, the user places the first flange plate 1 connected with the oil delivery pipe 8 on the surface of the air bag 3, so that the first flange plate 1 and the second flange plate 2 clamp and fix the air bag 3, then the plurality of bolts 6 are connected in position through the bolt holes 9 of the first flange plate 1, the second flange plate 2 and the air bag 3, and finally the plurality of nuts 7 are used for fixed connection.

[0028] In use, the high-temperature oil pump 10 inlet pipe and outlet pipe are both installed in the structure that the air bag 3 is arranged between the first flange plate 1 and the second flange plate 2, specifically, when the liquid in the high-temperature oil pump passes through the air bag 3, the liquid extrudes the air bag 3, and the hydraulic oil arranged in the air bag 3 extrudes other edges of the air bag 3, so that the air bag 3 is tightly combined with the groove 5, thereby further improving the sealing effect, and at the same time, the air bag 3 is extruded and fixed to the plurality of bolts 6 under the extrusion of the hydraulic oil, thereby further fastening the bolts.
