Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy pipelines, in particular to a leak-proof water conservancy pipeline used in water conservancy projects. Background Art

[0002] A water conservancy project is a project built to control and allocate natural surface water and groundwater to achieve the purpose of eliminating harm and promoting benefits. It is also called a water project. Water is a valuable resource indispensable to human production and life, but its natural state does not fully meet human needs. Only by building water conservancy projects can we control water flow, prevent floods and waterlogging disasters, and regulate and distribute water to meet the people's needs for water resources in life and production.

[0003] At present, the construction of water conservancy projects requires the use of water conservancy pipelines to facilitate the control of water flow. However, the existing water conservancy pipelines have poor sealing properties, and water leakage is prone to occur at the joints between pipelines, which affects the construction of water conservancy projects.

[0004] According to a leak-proof water conservancy pipeline for water conservancy projects disclosed in Chinese patent publication number CN217208226U, the patent solves the problem of water leakage at the pipe connection by designing the insertion groove inside the first connector and the second connector and the insertion tube, thereby preventing the waste of water resources.

[0005] The method and structure adopted by this patent are too simple, and no structural facilities are actually adopted for waterproofing, and it cannot completely guarantee that there will be no water leakage.

[0006] Therefore, we propose a leak-proof water conservancy pipeline for water conservancy projects to solve the problem. Utility Model Content

[0007] The utility model aims to provide a leak-proof water conservancy pipeline for water conservancy projects, which solves the problems in the above-mentioned background technology.

[0008] To achieve the above purpose, the utility model provides the following technical solution: a leak-proof water conservancy pipeline for water conservancy projects, comprising:

[0009] A first pipe, wherein a mounting groove is formed on the outside of the right end of the first pipe;

[0010] The second pipe has a left end whose inner portion is slidably sleeved on the mounting groove of the first pipe;

[0011] A guide block, the outer wall of which is fixedly installed with the inner wall of the right end of the first pipeline, and the right end surface of the guide block is respectively provided with an annular groove and a clamping groove;

[0012] A sealing ring is clamped in the annular groove on the right end face of the guide block, an outer wall sliding sleeve of the sealing ring is provided with an outer sealing ring, and an inner wall sliding sleeve of the sealing ring is provided with an inner sealing ring, the outer sealing ring and the inner sealing ring are both fixedly arranged on the inner wall of the annular groove, a limiting ring is fixedly installed on the right end face of the sealing ring, and the left side face of the limiting ring is respectively in contact with the right side faces of the first pipeline, the outer sealing ring and the inner sealing ring.

[0013] Preferably, a first flange is fixedly mounted on an outer wall of the first pipeline, and a second flange is fixedly mounted on an outer wall of the second pipeline, and the first flange and the second flange are connected by bolts.

[0014] Preferably, the inner wall of the guide block has a conical shape, and the right end of the guide block has an annular tubular shape. The conical shape of the inner wall of the guide block can reduce the water flow velocity and the water flow area. At the same time, the annular tubular shape of the right end of the guide block can further prevent water from directly contacting the connection between the first pipe and the second pipe. This can reduce the impact of the water flow on the connection and protect the leak-proof structure.

[0015] Preferably, the end surface of the outer sealing ring in contact with the limiting ring has a rounded corner, which facilitates the insertion of the sealing ring.

[0016] Preferably, the end surface of the inner sealing ring in contact with the limiting ring has a rounded corner, which facilitates the insertion of the sealing ring.

[0017] Preferably, a clamping ring is fixedly installed on the inner wall of the limiting ring, and the left end of the clamping ring is clamped with the groove on the right end face of the guide block, and the outer wall of the clamping ring is contacted with the inner wall of the inner sealing ring. The provided clamping ring can protect the sealing ring, the outer sealing ring and the inner sealing ring, especially by clamping the clamping ring with the groove on the right side of the guide block, which can prevent the infiltration of water, enhance the protection of the sealing ring, the outer sealing ring and the inner sealing ring, and enhance the leak-proof performance.

[0018] The utility model provides a leak-proof water conservancy pipeline for water conservancy projects. The leak-proof water conservancy pipeline for water conservancy projects has the following beneficial effects:

[0019] (1) The leak-proof water conservancy pipeline used in water conservancy projects can reduce the water flow velocity by setting the guide block, especially setting the inner wall of the guide block in a conical shape, while reducing the direct contact force of water with the connection between the first pipe and the second pipe, reducing the impact of the water flow on the connection, and protecting the leak-proof structure.

[0020] (2) The leak-proof water conservancy pipeline used in water conservancy projects can play a role in preventing water leakage through the provided sealing ring, outer sealing ring and inner sealing ring. In particular, the clamping ring is connected with the clamping groove on the right side of the guide block to avoid water infiltration, thereby strengthening the protection of the sealing ring, outer sealing ring and inner sealing ring, and enhancing the leak-proof performance.

[0032] The guide block 6 has an outer wall fixedly mounted on the inner wall of the right end of the first pipe 1, and the right end surface of the guide block 6 is respectively provided with an annular groove 12 and a clamping groove 13;

[0033] Among them, the inner wall of the guide block 6 has a conical shape, and the right end of the guide block 6 has an annular tubular shape. The conical shape of the inner wall of the guide block 6 can slow down the water flow speed and the water flow area. At the same time, the annular tubular shape of the right end of the guide block 6 can further prevent water from directly contacting the connection between the first pipe 1 and the second pipe 2, so that the impact of the water flow on the connection can be slowed down, and the leak-proof structure is protected.

[0034] The sealing ring 11 is clamped in the annular groove 12 on the right end face of the guide block 6. The outer wall sliding sleeve of the sealing ring 11 is provided with an outer sealing ring 7, and the inner wall sliding sleeve of the sealing ring 11 is provided with an inner sealing ring 10. The outer sealing ring 7 and the inner sealing ring 10 are fixedly arranged on the inner wall of the annular groove 12. The end face of the outer sealing ring 7 in contact with the limiting ring 9 has a rounded corner setting, and the end face of the inner sealing ring 10 in contact with the limiting ring 9 has a rounded corner setting. By setting the end faces of the outer sealing ring 7 and the inner sealing ring 10 with rounded corners, the sealing ring 11 can be smoothly clamped between the two. The right end face of the sealing ring 11 is fixedly installed with the limiting ring 9, and the left side face of the limiting ring 9 is respectively connected to the first pipeline 1 and the outer sealing ring 7 , and the right side of the inner sealing ring 10 is in contact with the setting, and the sealing ring 11, the outer sealing ring 7, and the inner sealing ring 10 can play a role in preventing water leakage. The inner wall of the limiting ring 9 is fixedly installed with a clamping ring 8, and the left end of the clamping ring 8 is clamped with the clamping groove 13 on the right end face of the guide block 6. The outer wall of the clamping ring 8 is in contact with the inner wall of the inner sealing ring 19. The setting of the clamping ring 8 can protect the sealing ring 11, the outer sealing ring 7, and the inner sealing ring 10, especially the clamping setting of the clamping ring 8 with the clamping groove 13 on the right side of the guide block 6 can avoid the infiltration of water flow, strengthen the protection of the sealing ring 11, the outer sealing ring 7, and the inner sealing ring 10, and strengthen the leakage-proof performance.

[0035] Working principle: first align the second pipe 2 with the installation groove of the first pipe 1, and then directly snap it in. At this time, the sealing ring 11 will be smoothly snapped in between the outer sealing ring 7 and the inner sealing ring 10, and the snap ring 8 will be snapped in the slot 13 on the right side of the guide block 6. Finally, the first flange 4 and the second flange 5 are connected by bolts, completing the purpose of installation, and also achieving the purpose of preventing water leakage inside the first pipe 1 and the second pipe 2.
