Description

Technical Field

[0001] The utility model relates to the technical field of sealing components, in particular to a quick-release high-performance mechanical sealing component. Background Art

[0002] Seals are components used to prevent the leakage of fluids or solid particles and the intrusion of foreign matter into machinery and equipment. They are typically made of materials such as rubber, plastic, or metal and have high wear and corrosion resistance, ensuring the normal operation of equipment and extending its service life. There are a variety of high-performance mechanical seals currently available on the market, but they still have some shortcomings.

[0003] Existing high-performance mechanical seals can improve the service life of seals by effectively reducing frictional heat. However, seals are generally connected to connectors by welding, which makes disassembly more troublesome. At the same time, due to the low contact friction, the seals and connectors are prone to loosening. In addition, after the seals and connectors are connected, there is no fixed position, which can easily cause the seals to shake and be damaged. For example, Chinese utility model patent with authorization publication number CN209354657U discloses a mechanical seal including a transmission seat, a dynamic ring seat and a static ring seat are provided in the transmission seat, the transmission seat is tightly fitted with the static ring seat through an elastic member, and a dynamic sealing ring and a static sealing ring are respectively provided on the dynamic ring seat and the static ring seat. The dynamic sealing ring and the static sealing ring are fitted and can rotate relative to each other. A sealing ring is provided between the dynamic ring seat and the dynamic sealing ring. A heat sink is provided on the outer diameter of the dynamic sealing ring. The heat sink is annular and sleeved on the outer wall of the dynamic sealing ring. A ridge is provided on the end surface of the heat sink facing the static ring seat, and the ridge is integral with the end surface of the heat sink. This utility model can effectively avoid direct friction between the end face of the heat sink and the stationary ring seat, thereby increasing the service life of the seal. However, this device can increase the service life of the seal by effectively reducing frictional heat. The seal is connected to the connector, and the seal is generally welded and installed, which is more troublesome to disassemble. At the same time, the seal and the connector are generally connected and installed due to the low contact friction, which is prone to the risk of loosening. In addition, after the seal and the connector are connected, there is no fixed position, which can easily cause the seal to shake and be damaged. Therefore, we propose a quick-release high-performance mechanical seal to solve the above problems. Utility Model Content

When the first sealing component body 1 and the second sealing component body 2 are connected to the connecting component from the front and rear directions, the gear 6 can fit with the connecting component to increase the friction between the first sealing component body 1 and the second sealing component body 2 and the connecting component. After the gear 6 fits with the connecting component, the first sealing component body 1 and the second sealing component body 2 will also fit tightly together, and the first fixing block 3 symmetrically installed on the outside of the first sealing component body 1 will be engaged with the second fixing block 4 symmetrically installed on the outside of the second sealing component body 2. The second fixing block 4 and the first fixing block 3 can be fixed by the first bolt 5, so that the first sealing component body 1 and the second sealing component body 2 are firmly installed on the outside of the connecting component. A sealing ring 7 is provided on the inner side of the first sealing body 1 and the second sealing body 2.

When the sealing ring 7 is snapped together, the first connecting block 8 and the second connecting block 9 on the outside of the sealing ring 7 will be snapped together. Then the threaded rod 10 is inserted into the first connecting block 8 and the second connecting block 9. The upper side of the threaded rod 10 is provided with a thread, which can be threadedly connected with the limit block 11. The limit block 11 will fit tightly with the top of the first connecting block 8, that is, the sealing ring 7 can be firmly fixed at the connection of the connector to enhance the sealing of its connection. After connection, since a support rod 13 is rotatably provided on the left rear side of the second sealing body 2, the support rod 13 can be rotated so that its right side is rotated and placed inside the support block 12 provided on the right rear side of the second sealing body 2.
