Description

Technical Field

[0001] This utility model relates to the field of pipe sealing equipment, and in particular to a high-pressure forged pipe end face sealing and leak-proof component. Background Technology

[0002] High-pressure forged pipe fittings, as core components for conveying high-pressure media, are widely used in petroleum, chemical, power, aerospace, and other fields. The sealing and leak-proof performance of their connections directly affects the operational safety, stability, and economy of the entire conveying system. Under high-pressure conditions, the medium is prone to leakage through the gaps in the pipe fitting connections, which not only wastes resources but may also cause safety accidents. Therefore, sealing and leak-proof components used for pipe fitting connections have become key supporting components to ensure the reliable operation of the system.

[0003] Currently, there are sealing and leak-proof components for high-pressure forged pipe fittings on the market, which can basically achieve the functions of sealing and positioning the pipe connection. Regarding positioning and disassembly, existing components mostly use bolt fastening or multiple sets of snap-fit ​​structures to fix the shell and pipe fitting. These structures require specialized tooling for assembly and positioning, and disassembly requires releasing each fastener individually, making the operation cumbersome and time-consuming. Furthermore, some snap-fit ​​structures are prone to wear and deformation after repeated disassembly and assembly, making them difficult to reuse and increasing maintenance material consumption and labor costs. In terms of sealing performance, the rubber seals of existing components are mostly pre-fixed, making it difficult to achieve precise initial alignment with the pipe connection. Moreover, the seals lack a stable locking structure after compression. Under the impact of high-pressure media and equipment vibration, the compression mechanism is prone to displacement, leading to a decrease in the fit between the seal and the connection, failing to form a continuous and stable all-around sealing surface, posing a certain risk of media leakage, and making it difficult to fully meet the harsh operating conditions of high-pressure forged pipe fittings.

[0004] In response to this technical problem, this application proposes a high-pressure forged pipe end face sealing and leak-proof component. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology and propose a high-pressure forged pipe end face sealing and leak-proof component. During assembly, the movable ball is embedded in the positioning groove and quickly positioned with the help of spring and movable rod. It can be disassembled and reused by pressing the button. The baffle helps the rubber ring to be accurately aligned, the rotating ring drives the push plate to squeeze and seal, and the positioning block is fixed to prevent displacement. The seal is stable and suitable for high-pressure working conditions.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A high-pressure forged pipe end face sealing and leak-proof assembly includes a first pipe and a housing. A baffle is fixedly connected to the inside of the left side of the housing. The outer wall of the first pipe is disposed inside the housing. A connecting assembly is disposed on the left side of the housing. A rubber ring is fixedly connected to the right side of the baffle. A flange is fixedly connected to the right end of the first pipe. The outer wall of the flange is disposed on the right side of the outer wall of the baffle. A second pipe is bolted to the right side of the first pipe. A rotating ring is rotatably connected to the middle outer wall of the housing. A pressing assembly is disposed inside the rotating ring. A positioning assembly is disposed on the upper side of the outer wall of the housing.

[0007] Furthermore, the connecting assembly includes a hole opened inside the left side of the housing, a movable ball is disposed inside the hole, a positioning groove is opened on the right outer wall of the first pipe, the outer wall of the movable ball is disposed inside the positioning groove, and a movable rod is slidably connected inside the housing, the outer wall of the movable rod is disposed on the upper side of the outer wall of the movable ball.

[0008] Furthermore, the extrusion assembly includes an auxiliary ring fixedly connected to the inner wall of the rotating ring, a connecting frame is provided inside the auxiliary ring, a push plate is fixedly connected to the lower side of the outer wall of the connecting frame, and the outer wall of the push plate is located on the right outer wall of the rubber ring.

[0009] Furthermore, the positioning component includes a push rod rotatably connected to the upper side of the outer wall of the housing, a positioning block fixedly connected to the right end of the push rod, a groove being formed on the outer wall of the rotating ring, and the outer wall of the positioning block being disposed inside the groove.

[0010] Furthermore, a button is fixedly connected to the left end of the movable rod, and the outer wall of the button is located on the outside of the housing.

[0011] Furthermore, a first spring is sleeved on the outer left side of the movable rod, and a connecting plate is fixedly connected to the outer left side of the movable rod. The outer wall of the connecting plate is located on the right side of the outer wall of the first spring.

[0012] Furthermore, the outer wall of the auxiliary ring is provided with a guide groove, the upper side of the outer wall of the connecting frame is disposed inside the guide groove, and the outer wall of the guide groove is slidably connected to the inner wall of the housing.

[0013] Furthermore, a telescopic rod is fixedly connected to the outer wall of the left side of the push rod, and the other side of the telescopic rod is fixedly connected to the upper side of the outer wall of the housing. A second spring is sleeved on the outer wall of the telescopic rod.

[0014] This utility model has the following beneficial effects: In this invention, during assembly, the housing achieves rapid pre-positioning by embedding an internal movable ball into the positioning groove of the fitting. The movable rod laterally limits the movable ball, and the spring force ensures secure positioning, allowing the housing to be fixed without complex tooling. For disassembly or replacement, simply press a button to drive the movable rod to slide. Its special structure can accommodate the movable ball and release the limit, allowing the housing to be easily removed. After releasing the button, the spring automatically drives the movable rod to reset, ensuring stable positioning for subsequent assembly. The entire process is simple, time-saving, and the components are reusable, reducing maintenance material consumption and labor costs.

[0015] In this invention, the baffle inside the shell precisely positions the pipe fitting connection, ensuring accurate initial alignment between the rubber ring and the connection. Through the linkage of the rotating ring and the auxiliary ring, the internal guide groove drives the connecting frame and push plate to directionally compress the rubber ring, causing the initially loose rubber ring to tightly fit against the edge of the connection, forming a comprehensive sealing surface. Simultaneously, the positioning block controlled by the push rod fixes the rotating ring, preventing displacement due to high-pressure vibration, ensuring a continuously stable sealing state, significantly reducing the risk of media leakage, and meeting the stringent sealing requirements of high-pressure forged pipe fittings.

[0018] 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.

[0019] Reference Figure 2 , Figure 3 and Figure 5 This utility model provides an embodiment of a high-pressure forged pipe end face sealing and leak-proof assembly, comprising a first pipe 3 and a housing 4. A baffle 7 is fixedly connected to the inside of the left side of the housing 4. The outer wall of the first pipe 3 is disposed inside the housing 4. A hole is provided on the left side of the housing 4, and a movable ball 11 is disposed inside the hole. A positioning groove 14 is opened on the outer wall of the right side of the first pipe 3, and the outer wall of the movable ball 11 is disposed inside the positioning groove 14. A movable rod 12 is slidably connected inside the housing 4, and the outer wall of the movable rod 12 is disposed on the upper side of the outer wall of the movable ball 11. A rubber ring 8 is fixedly connected to the right side of the baffle 7. A flange is fixedly connected to the right end of the first pipe 3, and the outer wall of the flange is disposed on the right side of the outer wall of the baffle 7. A second pipe 6 is bolted to the right side of the first pipe 3. A rotating ring 5 is rotatably connected to the middle outer wall of the housing 4. An auxiliary ring 10 is disposed inside the rotating ring 5. A connecting frame 16 is disposed inside the auxiliary ring 10. A push plate 15 is fixedly connected to the lower side of the outer wall of the connecting frame 16, and the outer wall of the push plate 15 is disposed on the outer wall of the right side of the rubber ring 8. A push rod 1 is provided on the upper side of the outer wall of the housing 4. A positioning block 9 is fixedly connected to the right end of the push rod 1. A groove is provided on the outer wall of the rotating ring 5. The outer wall of the positioning block 9 is located inside the groove.

[0020] Specifically, firstly, the first pipe fitting 3 and the second pipe fitting 6 are connected together and slid to the left side of the housing 4. Because the connection port is large, it is blocked by the baffle 7. The left side of the rubber ring 8 is fixedly connected to one side of the baffle 7, while the other side is loose. When the connection port abuts against the baffle 7, the rotating ring 5 can be rotated to squeeze the edge of the loose rubber ring 8, thus bringing it close to the edge of the connection port. During the above process, pressing the left side of the pressing rod 1 will cause the pressing rod 1 to rotate around the connection point, thereby lifting the positioning block 9 and allowing the rotating ring 5 to lose the constraint of the positioning block 9 and rotate freely, thereby driving the auxiliary ring 10 to rotate. When the auxiliary ring 10 rotates, the guide groove 17 inside the auxiliary ring 10 will guide the connecting frame 16 and the push plate 15 to press downward, thereby pressing the right side of the rubber ring 8 downward, so that the rubber ring 8 fits the connection port of the first pipe fitting 3 and the second pipe fitting 6, thereby improving the sealing performance of the device.

[0021] Pressing button 2 causes the movable rod 12 to slide to the left. The outer wall of the left side of the movable rod 12 has a structure with protrusions on both sides and a depression in the middle, which can receive the movable ball 11. This causes the movable ball 11 to lose the lateral force and leave the positioning groove 14 on the outer wall of the first pipe 3, so that it can be freely replaced and removed. After releasing the button, the movable rod 12 inside will abut against the first spring 13, so that the device structure is reset, thereby positioning the housing 4 on the upper side of the first pipe 3, which facilitates subsequent work. After the device is adjusted, the left side is blocked by the baffle 7, and the right side is blocked by the push plate 15 and the rubber ring 8 for reinforcement.

[0022] Reference Figure 1 , Figure 4 and Figure 6 A button 2 is fixedly connected to the left end of the movable rod 12, and the outer wall of the button 2 is located on the outside of the housing 4. A first spring 13 is sleeved on the left outer wall of the movable rod 12, and a connecting plate is fixedly connected to the left outer wall of the movable rod 12. The outer wall of the connecting plate is located on the right side of the outer wall of the first spring 13. A guide groove 17 is opened on the outer wall of the auxiliary ring 10, and the upper side of the outer wall of the connecting frame 16 is located inside the guide groove 17. The outer wall of the guide groove 17 is slidably connected to the inner wall of the housing 4. A telescopic rod 18 is fixedly connected to the left outer wall of the push rod 1, and the other side of the telescopic rod 18 is fixedly connected to the upper side of the outer wall of the housing 4. A second spring 19 is sleeved on the outer wall of the telescopic rod 18.

[0023] Specifically, the left end of the movable rod 12 is fixedly connected to the button 2, and the outer wall of the button 2 is exposed outside the housing 4. This design allows the operator to directly drive the movable rod 12 to slide by pressing the button 2 externally, controlling the state of the movable ball 11 without disassembling the housing 4, greatly improving operating efficiency. A first spring 13 is sleeved on the left outer wall of the movable rod 12, and a connecting plate is fixedly connected to its left outer wall. The outer wall of the connecting plate is attached to the right side of the outer wall of the first spring 13. When the button 2 is pressed, causing the movable rod 12 to move to the left, the connecting plate simultaneously squeezes the first spring 13 to deform and store force. After releasing the button, the elastic restoring force of the first spring 13 can push the connecting plate and the movable rod 12 to automatically reset, ensuring that the movable ball 11 can be stably inserted into the positioning groove 14 to achieve positioning. The auxiliary ring 10 has a guide groove 17 on its outer wall. The upper side of the outer wall of the connecting frame 16 is embedded in the guide groove 17, and the outer wall of the guide groove 17 is slidably connected to the inner wall of the housing 4. This guiding structure allows the guide groove 17 to convert the circular motion of the auxiliary ring 10 into the linear motion of the connecting frame 16 through cooperation with the connecting frame 16, accurately guiding the push plate 15 to squeeze the rubber ring 8 and ensuring uniform sealing pressure. The left outer wall of the push rod 1 is fixedly connected to the telescopic rod 18. The other end of the telescopic rod 18 is fixed to the upper side of the outer wall of the housing 4, and its outer wall is fitted with a second spring 19. When the push rod 1 is pressed, the telescopic rod 18 retracts and drives the second spring 19 to compress, and the positioning block 9 disengages from the groove of the rotating ring 5. After being released, the second spring 19 returns to its original position and pushes the push rod 1, so that the positioning block 9 automatically engages in the groove, realizing the rapid positioning and unlocking of the rotating ring 5.

[0024] Working principle: The flange on the right side of the first pipe fitting 3 is connected to the second pipe fitting 6 with bolts. One end of the rubber ring 8 is fixed to the outer wall of the left side baffle 7 inside the housing 4, and the other end of the rubber ring 8 is attached to the inner wall of the auxiliary ring 10. Then, the housing 4 is moved along the right side of the surface of the first pipe fitting 3 until the connection between the first pipe fitting 3 and the second pipe fitting 6 is blocked by the baffle 7 fixed inside the left side of the housing 4. At this time, the rubber ring 8 fixed to the right side of the baffle 7 forms the initial sealing base. Press the left side of the pressing rod 1 on the upper side of the outer wall of the housing 4, and the pressing rod 1 surrounds the connection. The rotation point drives the right-end positioning block 9 to lift, causing the positioning block 9 to disengage from the groove on the outer wall of the rotating ring 5, thus releasing the constraint on the rotating ring 5. The rotating ring 5 on the middle outer wall of the rotating housing 4 rotates accordingly, and the auxiliary ring 10 inside it rotates accordingly. The guide groove 17 inside the auxiliary ring 10 guides the connecting frame 16 to move downward. The push plate 15 fixed on the lower side of the outer wall of the connecting frame 16 simultaneously presses down on the right outer wall of the rubber ring 8, causing the loose rubber ring 8 to fit tightly against the outside of the flange at the connection end of the two pipe fittings, greatly improving the sealing and leak-proof performance.

[0025] Finally, the positioning structure enables the fixing and disassembly of the housing 4. During assembly, the movable ball 11 in the hole on the left side of the housing 4 is embedded in the positioning groove 14 on the outer right side of the first pipe 3, and the outer wall of the movable rod 12 presses against the upper side of the movable ball 11. With the help of the force of the first spring 13, the movable rod 12 is kept in position, thus achieving stable positioning of the housing 4 on the first pipe 3. When replacement or disassembly is required, press button 2 to slide the movable rod 12 to the left. The structure of the protrusions on both sides and the concave middle on the outer left side of the movable rod 12 receives the movable ball 11, so that the movable ball 11 loses its lateral constraint and leaves the positioning groove 14, and the housing 4 can be removed. After releasing the button, the first spring 13 returns to its original position and pushes the movable rod 12, and the device returns to its positioning state to facilitate subsequent work.

[0026] The circuits, protection devices, and pipe sealing devices involved in the above embodiments all adopt corresponding existing technologies according to the actual situation, and therefore will not be described in detail in the embodiments of this application.

[0027] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
