Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering technology, and in particular to a leak-proof structure for pipe interfaces. Background Technology

[0002] With the development of society, the application of pipelines has become increasingly widespread. Pipelines are devices made up of pipes, pipe fittings, valves, etc., used to transport gases, liquids, or fluids containing solid particles. Typically, after being pressurized by blowers, compressors, pumps, and boilers, fluids flow from high-pressure areas to low-pressure areas in pipelines. They can also be transported using the fluid's own pressure or gravity. Pipelines have a wide range of uses, mainly in water supply, drainage, heating, gas supply, long-distance transportation of oil and natural gas, agricultural irrigation, hydraulic engineering, and various industrial installations.

[0003] In the prior art, patent document with publication number (CN220016427U) mentions a leak-proof structure for a pipe interface, including a rotating clamp frame, a fixed frame, and a torsion block. An outer sealing strip is sealed to the inner and outer ends of the rotating clamp frame, and an interface sealing strip is fixedly connected to the middle position inside the rotating clamp frame. A fixed frame is fixedly connected to the right side of the rotating clamp frame, and a tightening strip is provided on the inner side of the rotating clamp frame. This prior art, through the setting of the outer sealing strip, tightening strip, and limiting teeth, utilizes the tightening strip to securely clamp the interface sealing strip, and the limiting teeth to limit the fixed teeth, ensuring that the side of the interface sealing strip tightly fits against the outer wall of the pipe interface, improving the pipe interface sealing performance. Simultaneously, the outer sealing strip can block the interface sealing strip, reducing the corrosive impact of the external environment on the interface sealing strip and improving its performance.

[0004] The aforementioned prior art connects the pipes by rotating the clamp frame, tightens the interface seal by tightening the tightening strip, and fixes it by limiting teeth. However, the tightening strip has a poor limiting effect, and the interface seal is easy to loosen. Utility Model Content

[0005] The purpose of this utility model is to provide a leak-proof structure for pipe interfaces, which solves the problems of poor tightening effect and easy loosening of interface seals in the existing technology.

[0006] To achieve the above objectives, this utility model provides a leak-proof structure for a pipe interface, comprising a first pipe body, a second pipe body, and a connecting mechanism. The first pipe body is disposed on one side of the second pipe body. The connecting mechanism includes a first ring, a second ring, a first connecting ring, a second connecting ring, four nuts, and four bolts. The first ring is fixedly connected to the first pipe body and located on one side of the first pipe body. The second ring is fixedly connected to the second pipe body and located on one side of the first ring. The first connecting ring is rotatably connected to the second connecting ring and covers the outside of the first and second rings. The first and second connecting rings are edge rings, and the cross-sections of the first and second connecting rings are both C-shaped. A first fixing plate and a second fixing plate are respectively disposed on both sides of the first and second connecting rings. The four nuts are rotatably connected to the corresponding second fixing plates and located below the corresponding second fixing plates. The four bolts pass through the corresponding first and second fixing plates and are threadedly connected to the corresponding nuts.

[0007] The first connecting ring has a connecting block on one side, and the second connecting ring has two rotating blocks on one side. The two rotating blocks are rotatably connected to the connecting block and are located on both sides of the connecting block.

[0008] The nut has a retaining ring at its upper end, which is rotatably connected to the second fixing plate and located inside the second fixing plate. The retaining ring has an L-shaped cross-section.

[0009] The first tube has a sealing ring on one side, and the second tube has a sealing groove on one side, with the sealing ring and the sealing groove being adapted to each other.

[0010] The first ring and the second ring are provided with several protrusions on their surfaces, and the first ring and the second ring are engaged.

[0011] This utility model discloses a leak-proof structure for a pipe interface. A first ring is fixedly connected to the first pipe body and located on one side of the first pipe body. A second ring is fixedly connected to the second pipe body and located on one side of the first ring. A first connecting ring is rotatably connected to the second connecting ring and covers the outside of the first and second rings. The first and second connecting rings are edge-ring shaped, and their cross-sections are both C-shaped. A first fixing plate and a second fixing plate are respectively provided on both sides of the first and second connecting rings. Four nuts are rotatably connected to the corresponding second fixing plates and located below them. Four bolts pass through the corresponding first and second fixing plates and are threadedly connected to the corresponding nuts. This brings the first and second pipe bodies into contact, aligns the first and second rings, covers the outside of the first and second rings, and tightens the four bolts and nuts to fix the corresponding first and second fixing plates, thus connecting the first and second pipe bodies and improving sealing.
