Description

Technical Field

[0001] The utility model relates to the technical field of sealing ring structures, in particular to a sealing ring structure which can prevent deformation of a mechanical seal during installation. Background Art

[0002] When mechanical seals are installed, sealing rings are used to seal between two machines. Conventional graphite sealing rings are only made of graphite powder. Although their sealing performance is relatively good, graphite has poor toughness and is easily worn. After a period of use, the mechanical sealing effect of the mechanical sealing surface cannot be guaranteed. Moreover, when two machines are installed, the rigid docking will cause the machine to deform, thus affecting the sealing effect.

[0003] According to the description of a graphite sealing ring and mechanical sealing structure disclosed on the patent website (authorization announcement number: CN217898772U), "The utility model relates to the field of mechanical sealing technology, specifically to a graphite sealing ring and a mechanical sealing structure. The graphite sealing ring includes a sealing ring body, the sealing ring body includes a coaxial and fixedly connected graphite ring and a wear-resistant sleeve, the wear-resistant sleeve is provided with a groove and a sealing ring arranged in the groove, and the wear-resistant sleeve is provided with a positioning pin at one end away from the graphite ring. The stainless steel carrier and the carbon graphite are combined into one, and the graphite sealing ring structure is designed by utilizing the respective characteristics of the stainless steel carrier and the carbon graphite to make up for the shortcomings of insufficient toughness of graphite; carbon graphite and stainless steel surfaces are used as sealing surfaces, and carbon graphite has good sealing properties as conventional consumables, and stainless steel surfaces are used as reference surfaces. Graphite particles with small sealing properties are used as sealing media. Stainless steel has high hardness and slow wear, which effectively improves the overall performance."

[0004] During use, the utility model combines a stainless steel carrier and carbon graphite into one, utilizes the respective characteristics of the stainless steel carrier and carbon graphite to design a graphite sealing ring structure, and compensates for the insufficient toughness of graphite. However, one side of the graphite still adheres to the inner wall of the workpiece, and the rotation of the sealing ring after installation will still cause wear. At the same time, when two machines are connected, the hard sealing ring cannot protect the two machines well, and will cause the two machines to deform. Therefore, it is necessary to improve a sealing ring structure that can prevent deformation of the mechanical seal during installation to solve the above problems. Utility Model Content

[0005] The utility model aims to provide a sealing ring structure which can prevent the mechanical seal from being deformed during installation.

[0006] The utility model provides the following technical solutions:

[0007] The utility model proposes a sealing ring structure for preventing deformation of a mechanical seal during installation, comprising a first cylindrical mechanical connector and a second mechanical connector, wherein the second mechanical connector is sleeved in the first mechanical connector, an anti-deformation mechanism is arranged between the first mechanical connector and the second mechanical connector, and an annular sealing ring is arranged between the anti-deformation mechanism and the first mechanical connector; the anti-deformation mechanism comprises a support plate extending from the sealing ring toward the second mechanical connector and a rubber ring buckled on the outer edge of the support plate.

[0008] An installation groove is provided in the first mechanical connector, the sealing ring is provided in the installation groove, a return spring is provided in the side wall of the installation groove, one end of the return spring is fixed in the installation groove, a latch is fixed on the side of the return spring facing the sealing ring, and a socket corresponding to the latch is provided on the outer wall of the sealing ring.

[0009] The number of the return springs and the latches is four, and they are evenly arranged on the inner wall of the first mechanical connector.

[0010] The support plate is fixedly connected to the rubber ring via screws.

[0011] An upper anti-loosening washer and a lower anti-loosening washer are arranged between the rubber ring and the head of the screw.

[0012] The surfaces of the upper anti-loosening washer and the lower anti-loosening washer are both provided with anti-loosening teeth, and the anti-loosening teeth on the facing surfaces of the upper anti-loosening washer and the lower anti-loosening washer bite each other.

[0013] Compared with the prior art, the utility model installs the sealing ring into the interior of the installation groove, and under the action of the reset spring, the pin is inserted into the interior of the sealing ring, thereby preventing the sealing ring from rotating after installation, reducing the wear of the sealing ring and increasing the service life of the sealing ring. At the same time, the sealing ring structure is installed on the outside of the installation support plate through the rubber ring, and the rubber ring is fixed to the installation support plate by screwing the installation screw into the screw hole. The rubber ring reduces the force of the mechanical device installed in the mechanical connector in actual application, and prevents the deformation of the machine when it is installed in the utility model in actual application.

[0024] In the above embodiment, the sealing ring 4 is a graphite sealing ring.

[0025] In one embodiment of the utility model, a mounting groove 7 is provided in the first mechanical connector 1, the sealing ring 4 is provided in the mounting groove 7, a return spring 8 is provided in the side wall of the mounting groove 7, one end of the return spring 8 is fixed in the mounting groove 7, a latch 9 is fixed on the side of the return spring 8 facing the sealing ring 4, and a socket 10 corresponding to the latch 9 is provided on the outer wall of the sealing ring 4; the sealing ring 4 is prevented from rotating after installation, the wear of the sealing ring 4 is reduced, and the service life of the sealing ring 4 is increased.

[0026] In the above embodiment, there are four return springs 8 and four latches 9, which are evenly arranged on the inner wall of the first mechanical connector 1, so that the sealing ring 4 is fixed more firmly.

[0027] In an embodiment of the present invention, the support plate 5 and the rubber ring 6 are fixedly connected by screws 11 .

[0028] In the above embodiment, an upper anti-loosening washer 12 and a lower anti-loosening washer 13 are arranged between the rubber ring 6 and the head of the screw 11 to prevent the screw 11 from loosening.

[0029] In the above embodiment, the surfaces of the upper anti-loosening washer 12 and the lower anti-loosening washer 13 are both provided with anti-loosening teeth, and the anti-loosening teeth on the facing surfaces of the upper anti-loosening washer 12 and the lower anti-loosening washer 13 are engaged with each other.
