[0023] Further, the clamping blocks 3 and the condenser pipes 4 are provided with three same sizes, and are distributed at equal distances around the fixing member 1, through the arrangement of the clamping blocks 3 and the condenser pipes 4, the condenser pipes 4 fixed by the clamping blocks 3 can quickly absorb the heat of the heat dissipation fins 5 to cool down, three condenser pipes 4 work at the same time with short distance distribution, which greatly increases the heat dissipation area and significantly shortens the heat dissipation time, so that the equipment can be quickly cooled down during operation, and the stable operation of the equipment is effectively maintained.

[0024] Furthermore, multiple heat sinks 5 of the same size are provided and distributed at equal distances along the condenser tube 4. Through the arrangement of heat sinks 5 and condenser tube 4, during use, multiple heat sinks 5 will quickly absorb the heat generated by gas compression and mechanical component friction and transfer it to the condenser tube 4, which greatly increases the heat dissipation area, ensures stable operation of the compressor, and reduces performance degradation caused by overheating.

[0025] Furthermore, the locking block 3 and the groove 7 are provided with three of the same size. The outer wall size of the locking block 3 matches the inner wall size of the groove 7. Through the setting of the locking block 3 and the groove 7, during use, the locking block 3 will restrict the groove 7 to prevent the parts from rotating together under the action of friction torque, which greatly improves the overall stability of the equipment, prevents equipment failure caused by loosening or displacement of parts, and ensures long-term stable operation of the equipment.

[0026] Furthermore, the threaded groove 905 is adapted to the first thread 902 and the second thread 915, and the rotating ring seat 901 and the seal 914 are distributed in parallel. Through the setting of the threaded groove 905, the first thread 902 and the second thread 915, in use, the threaded groove 905 connects the rotating ring seat 901 and the seal 914 through the first thread 902 and the second thread 915. When the parts are worn or damaged, they can be replaced quickly, effectively shortening the equipment downtime and improving production efficiency.

[0027] Furthermore, the inner wall dimensions of the first arc groove 908 and the second arc groove 910 are the same, and the connection port 907 and the stationary ring seat 911 are distributed in parallel. Through the setting of the first arc groove 908 and the second arc groove 910, during use, the first arc groove 908 and the second arc groove 910 will fit tightly together and clamp the sealing ring, reducing displacement. This fitting method greatly reduces the gap between the sealing ring and the surrounding components, effectively preventing gas from leaking through the gap, and significantly improving the overall sealing performance of the sealing device.

[0028] Furthermore, the outer wall dimensions of the arc block 912 match the inner wall dimensions of the slide groove 913, and the outer dimensions of the second sealing ring 909 are the same as those of the first sealing ring 903. Through the arrangement of the arc block 912 and the slide groove 913, the slide groove 913 will restrict the arc block 912 during use, thereby enhancing the stability of the overall sealing structure and ensuring the stable operation of the compressor.

[0029] Working principle: During use, the first sealing ring 903 and the second sealing ring 909 act as sealing end faces. When the device needs to be replaced or maintained, the assembly 9 is set up to first turn the component 904 to separate the threaded groove 905 from the moving ring seat 901 connected to the first thread 902 and the stationary ring seat 911 connected to the second thread 915. At the same time, the limiting plate 906 connected to the component 904 will lose its restriction on the connection port 907. Remove the connection port 907 to move the first arc groove 908 away from the seal 914, and then remove the seal 914 away from the stationary ring seat 911. The second sealing ring 909 can be quickly positioned, replaced and maintained through the second arc groove 910 and the first arc groove 908. In the actual process, the spring seat 6 positions the auxiliary spring 8 to make its spring force evenly distributed in the direction of the sealing end face. When a large amount of heat is generated due to gas compression and mechanical component friction, multiple heat sinks 5 will quickly absorb the heat and then evenly distribute the heat through the condenser tube 4 to control the temperature of the device. This completes the use process of a sealing device for a gas compressor.
