Description

Technical Field

[0001] This utility model relates to the field of double rubber ring joint technology, and in particular to a double rubber ring joint sealing method. Background Technology

[0002] A double-ring joint refers to a pipe connection fitting in which two independent sealing rings are configured in a pre-sealed cavity of the pipe connection interface. Through the elastic recovery force of the rings themselves, the self-tightening effect of the pipe medium pressure, or the auxiliary compression of the mechanical structure, the two rings form a double-fit seal with the inner surface of the socket and the outer surface of the spigot, respectively.

[0003] In the existing technology, there are many types of double rubber ring joints, which represent different diameters and naturally different connection methods, including threaded connections. With the help of the rubber ring, the elasticity and restoring force of the rubber itself helps to fit the contact surface, while also offsetting the impact of non-round sockets that may occur during pipe production, thus greatly reducing the chance of leakage. However, after the socket is connected to the spigot, the rubber ring relies on its own elasticity to contact the contact surface. The rubber ring only contacts the contact surface through its own elasticity and lacks the forced compression constraint of the mechanical structure. When the pipeline is subjected to temperature changes, the rubber ring may change, resulting in insufficient tightness between the rubber ring and the contact surface, and thus loosening of the seal. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies and provide a double rubber ring joint sealing method.

[0008] In a preferred embodiment, a sub-rod is provided at one end of the arc-shaped plate, and one end of the arc-shaped plate is fixedly connected to one side of the circumference of the sub-rod. A fixing member is provided on the inner wall of the sub-rod, and the inner wall of the sub-rod is threadedly connected to the outer side of the fixing member.

[0009] In a preferred embodiment, a female rod is provided on the outer side of one end of the fixing member, and the outer side of one end of the fixing member is threadedly connected to the inner wall of the female rod.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0021] like Figure 1-5As shown, this utility model provides a technical solution: a double rubber ring joint sealing form, including a socket 11, a spigot 12 provided on the inner surface of one end of the socket 11, the inner surface of one end of the socket 11 being threadedly connected to the outer surface of one end of the spigot 12, a rubber ring 14 provided on one end of the spigot 12, the one end of the spigot 12 contacting the one end of the rubber ring 14, a conical ring 13 provided on the inner side of the rubber ring 14, the inner side of the rubber ring 14 slidingly contacting the inclined surface of the conical ring 13. Connecting the conical ring 13, one end is provided with a connecting plate 15, and one end of the conical ring 13 is fixedly connected to one end of the connecting plate 15. A pull rod 16 is provided in the recessed part of one end of the connecting plate 15, and the recessed part of the connecting plate 15 slides in contact with one side of the pull rod 16. A fitting plate 17 is provided at the top of the pull rod 16, and the top of the pull rod 16 is fixedly connected to the bottom side of the fitting plate 17. The outer side of the fitting plate 17 fits into the inner wall of the socket 12, and the top side of the fitting plate 17 is provided with... A fixed base 18 is provided, and the top side of the fitting plate 17 contacts the bottom end of the fixed base 18. An arc-shaped plate 19 is provided on the inner side of one end of the fixed base 18, and the inner side of one end of the fixed base 18 is rotatably connected to one end of the arc-shaped plate 19. A sub-rod 112 is provided on one end of the arc-shaped plate 19, and one end of the arc-shaped plate 19 is fixedly connected to one side of the circumference of the sub-rod 112. A fastener 111 is provided on the inner wall of the sub-rod 112, and the inner wall of the sub-rod 112 is threaded to the outer side of the fastener 111. The fastener 111 has a female rod 113 on its outer side at one end. The outer side of the fastener 111 is threaded to the inner wall of the female rod 113. One end of the female rod 113 is fixedly connected to one side of the circumference of the socket 12. One end of the male rod 112 contacts one end of the female rod 113. A second rubber ring 114 is provided on the outer side of the socket 12. The outer side of the socket 12 is fixedly connected to the inner side of the second rubber ring 114. The outer side of the second rubber ring 114 contacts the inner surface of the socket 11.

[0022] In this embodiment, when using this type of double rubber ring joint seal, the diameter of one end of the socket 11 is larger than that of the insertion port 12, and the socket 11 and insertion port 12 are fitted with threaded installation. A second rubber ring 114 is located on the outside of the insertion port 12. After the insertion port 12 enters the inner surface of the socket 11, the elastic restoring force of the rubber ring 114 keeps it in contact with the metal surface, thereby achieving a sealing effect. A conical ring 13 is designed at one end of the insertion port 12, protruding from the end of the insertion port 12. A second rubber ring 114 is designed between the conical ring 13 and the insertion port 12, and the second rubber ring 114 is also responsible for contacting the inner surface of the socket 11. Therefore, a connecting plate 15 is connected to one end of the conical ring 13. The connecting plate 15 is annular and has a protrusion, and a recess is formed on the protrusion. A groove is formed on one side of the insertion port 12, which can fit with the fitting plate 17. A pull rod 16 is located on one side of the 17. The bottom end of the pull rod 16 has a bevel. By fitting the fitting plate 17 into the upper groove of the socket 12, the pull rod 16 enters the interior of the socket 12. At the same time, the bevel at the bottom end of the pull rod 16 contacts the recess on the connecting plate 15. During the downward movement of the pull rod 16, the external force of the vertical bevel will cause the connecting plate 15 to move to one side. The movement of the connecting plate 15 will simultaneously drive the cone ring 13. The cone ring 13 also has a bevel. The bevel expands the rubber ring 14, allowing it to spread evenly along the inner wall of the socket 11 and form a tightly fitting sealing surface with the inner surface of the socket 11, achieving double sealing protection. This method allows the rubber ring 14 to generate continuous pressure on the metal contact surface, enhancing the sealing reliability. At the same time, it can also compensate for slight eccentricity that may occur during pipeline installation, forming a double redundant sealing structure, effectively blocking the medium leakage path. The design incorporates a fixed base 18 with two inner ends connected to an arc-shaped plate 19 via rotating components. One end of the arc-shaped plate 19 has a male rod 112, while the two sides of the socket 12 have female rods 113. By positioning the fixed base 18 on the top side of the fitting plate 17 and then moving the arc-shaped plate 19, the male rod 112 contacts the female rod 113. At this point, the male rod 112 and female rod 113 are threadedly fixed using a fastener 111, ensuring that the fitting plate 17 always maintains a tight fit with the socket 12 slot. Simultaneously, the curvature of the arc-shaped plate 19 matches the outer surface contour of the socket 12, forming a ring-shaped support after fitting, dispersing the concentrated force at the fixing point, and ensuring the mechanical fixing and sealing structure of the entire connector. Example

[0023] like Figure 1-5 As shown, a positioning rod 110 is provided on the top side of the bonding plate 17. The top side of the bonding plate 17 is fixedly connected to the bottom end of the positioning rod 110, and the outer side of the positioning rod 110 is connected through to the inner wall of the fixing seat 18.

[0024] In this embodiment, a positioning rod 110 is installed on the top side of the bonding plate 17. The positioning rod 110 also serves as a handle to facilitate the removal of the bonding plate 17 from the slot of the insertion port 12. At the same time, when the fixing seat 18 is located on the bonding plate 17, there is a reserved hole at the middle of the fixing seat 18. By combining the hole with the positioning rod 110, the fixing seat 18 and the bonding plate 17 can be quickly pre-positioned. Furthermore, the rigid cooperation between the positioning rod 110 and the hole disperses the force on the arc plates 19 on both sides of the fixing seat 18, preventing the fixing seat 18 from shifting during long-term use, thereby ensuring the stability of the threaded connection between the sub-rod 112 and the mother rod 113.

[0025] Working principle: like Figure 1-5 As shown, by connecting the socket 12 and the receptacle 11, the elastic restoring force of the rubber ring 114 keeps it in contact with the metal surface after the socket 12 enters the inner surface of the receptacle 11, thereby achieving a sealing effect. By fitting the fitting plate 17 into the upper groove of the socket 12, the pull rod 16 enters the interior of the socket 12. At the same time, the bottom inclined surface of the pull rod 16 contacts the recess on the connecting plate 15. During the downward movement of the pull rod 16, the external force of the vertical inclined surface will cause the connecting plate 15 to move to one side. The movement of the connecting plate 15 will synchronously drive the cone ring 13. The conical ring 13 also has a bevel. The bevel expands the rubber ring 14, allowing it to spread evenly along the inner wall of the socket 11 and form a tight sealing surface with the inner surface of the socket 11, achieving double sealing protection. Finally, a positioning rod 110 is installed on the top side of the bonding plate 17. The positioning rod 110 also serves as a handle to facilitate the removal of the bonding plate 17 from the groove of the insertion port 12. At the same time, when the fixing seat 18 is located on the bonding plate 17, there is a reserved hole in the middle of the fixing seat 18. By combining the hole with the positioning rod 110, the fixing seat 18 and the bonding plate 17 can be quickly pre-positioned.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
