Description

Technical Field

[0001] This utility model relates to the field of flange installation technology, specifically to a leak-proof structure for a general equipment sealing flange. Background Technology

[0002] A flange, also called a flange plate or flange, is a part used to connect pipes to each other, used for connecting pipe ends; flanges are also used on equipment inlets and outlets for connecting two pieces of equipment, such as gearbox flanges. A flange connection or flange joint refers to a detachable connection consisting of a flange, gasket, and bolts connected together as a combined sealing structure. Pipe flanges refer to flanges used for piping in pipeline installations, while those used on equipment refer to the inlet and outlet flanges of the equipment. Flanges have holes, bolts are used to tightly connect two flanges, and a gasket is used to seal between the flanges.

[0003] Patent CN220749358U proposes a leak-proof sealing flange. By creating a groove on the outer side of the first flange body and installing a positioning block on the outer side of the second flange, with the positioning block installed at the same position as the groove, positioning can be quickly achieved by aligning the positioning block of the second flange with the groove in the first flange body. This aligns all the connection holes, reducing the time wasted on connecting the holes. By placing a separator between the two flanges, which uses the lever principle and treats the second flange as a fulcrum to apply force to the first flange body, the operator can maximize the force used when separating the flanges, achieving the goal of conveniently separating the flanges while effectively utilizing the user's strength.

[0004] While the above solution offers convenience in disconnecting the two mating flanges, it requires the installation of additional piping at the flange's axial center. The sealing of this connection is typically achieved using a sealing ring, which results in poor sealing performance. Utility Model Content

[0005] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a leak-proof structure for a universal equipment sealing flange to solve the problems mentioned in the background. This utility model has a novel structure, in which the inner cylinders and outer rings of two flanges are joined together. After being inserted by the pins of the locking assembly, they are locked by locking bolts. The arc block in the inner cylinder is pushed out by the transmission assembly and merged with the rubber block into a complete ring. This not only locks the connection between the inner cylinder and the pipeline, but also enhances the stability when the inner cylinder is connected to other pipelines.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a leak-proof structure for a general-purpose equipment sealing flange, comprising an inner cylinder, an outer ring fixed to one end of the inner cylinder, two sets of inner cylinders and outer rings joined together, a locking assembly mounted on the surface of the outer ring, the locking assembly comprising a circular ring attached to the surface of the outer ring, a limiting cylinder fixed to the outer surface of the outer ring, the circular ring slidably sleeved on the limiting cylinder, the limiting cylinder surrounding the inner cylinder, a transmission assembly provided in the limiting cylinder, the transmission assembly comprising a vertical column slidably inserted into the inner cylinder, an arc block slidably inserted into the inner wall of the inner cylinder on the side away from the outer ring at a position corresponding to the vertical column, and the top of the vertical column and the arc block being fixedly connected.

[0007] Furthermore, the locking assembly also includes inserts. Nine inserts are fixed at equal intervals on the circular surface of one side of the two sets of outer rings, and the inserts slide through the two outer rings. Insertion holes are opened on the circular surface of the other side of the outer ring corresponding to the positions of the inserts, and the inserts slide out of the insertion holes.

[0008] Furthermore, ear plates are fixed on both sides of the outer ring, and locking bolts are threaded between the two sets of ear plates.

[0009] Furthermore, the transmission assembly also includes a horizontal plate, with the horizontal plate fixed to the top of each vertical column corresponding to the ring, and a connecting rod rotatably connected to the surface of the horizontal plate, the other end of which is rotatably connected to the vertical column via a rotating shaft.

[0010] Furthermore, the inner cylinder has a storage groove at the top of the corresponding arc block, the vertical column slides through the storage groove and is fixedly connected to the arc block, and the surface of the limiting cylinder has a movable notch at the position corresponding to the horizontal plate, and the ring is fixedly connected to the horizontal plate through the movable notch.

[0011] Furthermore, a vertical plate is fixed to the end of the horizontal plate away from the ring, and the top of the vertical plate is slidably inserted into the surface of the horizontal plate, and a rubber ring is fixed to the bottom of the vertical plate.

[0012] Furthermore, a spring is fixed to the top of the vertical plate extending through the horizontal plate, and the other end of the spring is fixedly connected to the horizontal plate.

[0013] Furthermore, a rubber block is fixed on the inner wall of the inner cylinder between the two arc blocks, and the arc blocks and the rubber block are combined into a complete ring.

[0014] The beneficial effects of this utility model are:

[0015] 1. This utility model uses a locking component to lock the pipe into the inner cylinder. Through the cooperation of the transmission component and the locking component, the pipe inserted into the inner cylinder is clamped and fixed while the two outer rings are locked and connected, maintaining the sealing of the outer ring connection and the connection between the pipe and the inner cylinder, and facilitating subsequent disassembly.

[0016] 2. In this utility model, after the circular ring is tightly attached to the outer ring, the insert passes through the two outer rings and another set of circular rings, and then the flange is locked on the ear plates on both sides by locking bolts.

[0017] 3. This utility model uses the movement of the ring to move the horizontal plate along with the ring through the moving notch. The connecting rod drives the vertical column to move upward, and the arc block is stored in the storage groove. This releases the inner cylinder from clamping and fixing the pipe. When the arc block extends, it can clamp and fix the pipe. After merging with the rubber block, it wraps the pipe from the inside of the inner cylinder.

[0018] 4. In this invention, after the two rings are unlocked, the rings are pulled outward along the limiting cylinder, and the horizontal plate and vertical rod move outward simultaneously. The rubber ring leaves the port of the inner cylinder. At the same time, the vertical rod, no longer squeezed by the limiting cylinder, moves upward by the spring force. The vertical plate pulls the rubber ring to deform. The elastic rubber ring can easily insert the pipe into the inner cylinder after deformation. Similarly, when the ring is attached to the outer ring, the top of the vertical plate is squeezed by the limiting cylinder, causing the rubber ring to shrink into a ring shape and seal the outermost end of the port of the inner cylinder.

[0019] 5. Compared with the prior art, the inner cylinder and outer ring of the two sets of flanges are connected together. After being inserted by the plug of the locking component, they are locked by the locking bolt. The arc block in the inner cylinder is pushed out by the transmission component and merged with the rubber block into a complete ring. This not only locks the connection between the inner cylinder and the pipeline, but also enhances the stability when the inner cylinder is connected to other pipelines. Attached Figure Description

[0026] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0027] Please see Figures 1 to 5 This utility model provides a technical solution: a leak-proof structure for a universal equipment sealing flange, including an inner cylinder 1. An outer ring 11 is fixed to one end of the inner cylinder 1. Two sets of inner cylinders 1 and outer rings 11 are joined together. A locking component 2 is installed on the surface of the outer ring 11. The locking component 2 includes a circular ring 22, which is attached to the surface of the outer ring 11. A limiting cylinder 26 is fixed to the outer surface of the outer ring 11, and the circular ring 22 is slidably sleeved on the limiting cylinder 26. The limiting cylinder 26 surrounds the inner cylinder 1. A transmission component 3 is provided in the limiting cylinder 26. Component 3 includes a vertical column 36, which is slidably inserted into the inner cylinder 1. An arc block 33 is slidably inserted into the inner wall of the inner cylinder 1 on the side away from the outer ring 11, corresponding to the position of the vertical column 36. The top of the vertical column 36 and the arc block 33 are fixedly connected. When using the device, the inner cylinder 1 and the outer ring 11 are aligned and locked by the locking component 2. The pipe is then inserted into the inner cylinder 1. Through the cooperation of the transmission component 3 and the locking component 2, the pipe inserted into the inner cylinder 1 is clamped and fixed while the two outer rings 11 are locked and connected, maintaining the sealing of the connection between the outer rings 11 and the connection between the pipe and the inner cylinder 1, and facilitating subsequent disassembly.

[0028] In this embodiment, the locking assembly 2 further includes insert pins 21. Nine insert pins 21 are equidistantly fixed on the surface of the circular rings 22 on one side of the two sets of outer rings 11, and the insert pins 21 slide through the two outer rings 11. The circular rings 22 on the other side of the outer ring 11 have insertion holes 23 corresponding to the positions of the insert pins 21. The insert pins 21 slide out of the insertion holes 23. Ear plates 24 are fixed on both sides of the outer ring 11. Locking bolts 25 are threaded between the two sets of ear plates 24. After the circular rings 22 are pressed against the outer rings 11, the insert pins 21 pass through the two outer rings 11 and the other set of circular rings 22, and then the flanges are locked on the ear plates 24 by the locking bolts 25.

[0029] In this embodiment, the transmission assembly 3 further includes a horizontal plate 35. The ring 22 is fixed to the top of each vertical column 36 via the horizontal plate 35, and a connecting rod 37 is rotatably connected to the surface of the horizontal plate 35. The other end of the connecting rod 37 is rotatably connected to the vertical column 36 via a rotating shaft. The inner cylinder 1 has a receiving groove 39 at the top corresponding to the arc block 33. The vertical column 36 slides through the receiving groove 39 and is fixedly connected to the arc block 33. The surface of the limiting cylinder 26 has a moving notch 27 at the position corresponding to the horizontal plate 35. The ring 22 connects to the horizontal plate 36 via the moving notch 27. A horizontal plate 35 is fixedly connected. A rubber block 32 is fixed on the inner wall of the inner cylinder 1 between two arc blocks 33. The arc blocks 33 and the rubber block 32 are combined into a complete ring. As the ring 22 moves, the horizontal plate 35 moves with the ring 22 through the moving notch 27. The connecting rod 37 drives the vertical column 36 to move upward, so that the arc block 33 is stored in the storage groove 39. This releases the clamping and fixing of the pipe by the inner cylinder 1. When the arc block 33 extends, it can clamp and fix the pipe. After merging with the rubber block 32, it wraps the pipe from the inside of the inner cylinder 1.

[0030] In this embodiment, a vertical plate 34 is fixed to one end of the horizontal plate 35 away from the ring 22, and the top of the vertical plate 34 is slidably inserted into the surface of the horizontal plate 35. A rubber ring 31 is fixed to the bottom of the vertical plate 34, and a spring 38 is fixed to the top of the vertical plate 34 through the horizontal plate 35. The other end of the spring 38 is fixedly connected to the horizontal plate 35. After the two rings 22 are unlocked, the rings 22 are pulled outward along the limiting cylinder 26, and the horizontal plate 35 and the vertical rod move outward synchronously. The rubber ring 31 leaves the port of the inner cylinder 1. At the same time, the vertical rod is no longer squeezed by the limiting cylinder 26 and moves upward by the elastic force of the spring 38. The vertical plate 34 pulls the rubber ring 31 to deform. After the elastic rubber ring 31 is deformed, it is convenient to insert the pipe into the inner cylinder 1. Similarly, when the ring 22 is attached to the outer ring 11, the top of the vertical plate 34 is squeezed by the limiting cylinder 26, causing the rubber ring 31 to shrink into a ring shape and seal the outermost end of the port of the inner cylinder 1.

[0031] When using the device, align the inner cylinder 1 and outer ring 11. After the ring 22 is pressed tightly against the outer ring 11, the insert pin 21 passes through the two outer rings 11 and another set of rings 22. Then, lock the flanges on the two side ear plates 24 with locking bolts 25. Insert the pipe into the inner cylinder 1. Through the cooperation of the transmission component 3 and the locking component 2, the horizontal plate 35 moves with the ring 22 through the moving notch 27 as the ring 22 moves. The connecting rod 37 drives the vertical column 36 to move upward, storing the arc block 33 into the storage groove 39. This releases the clamping and fixing of the pipe by the inner cylinder 1. When the arc block 33 extends, it can clamp and fix the pipe. After merging with the rubber block 32, it wraps around the pipe from inside the inner cylinder 1. The two outer rings 11 are locked. While the connection is being made, the pipe inserted into the inner cylinder 1 is clamped and fixed to maintain the seal at the connection of the outer ring 11 and the connection between the pipe and the inner cylinder 1. After the two rings 22 are unlocked, the rings 22 are pulled outward along the limiting cylinder 26. The horizontal plate 35 and the vertical rod move outward synchronously. The rubber ring 31 leaves the port of the inner cylinder 1. At the same time, the vertical rod, no longer squeezed by the limiting cylinder 26, moves upward by the elastic force of the spring 38. The vertical plate 34 pulls the rubber ring 31 to deform. The elastic rubber ring 31 can easily insert the pipe into the inner cylinder 1 after deformation. Similarly, when the ring 22 is attached to the outer ring 11, the top of the vertical plate 34 is squeezed by the limiting cylinder 26, causing the rubber ring 31 to shrink into a ring shape and seal the outermost end of the port of the inner cylinder 1.

It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model.

[0033] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
