Description

Technical Field

[0001] This utility model belongs to the field of high-pressure pump connection technology, specifically relating to a high-pressure pump body connection device. Background Technology

[0002] In industrial production scenarios, high-pressure pumps need to be connected to pipelines via specific connection devices to achieve stable transmission of high-pressure fluids. This connection process is a core component ensuring the normal operation of the high-pressure pump. If the connection is not reliable enough, it will not only affect the fluid transmission efficiency but may also cause safety hazards due to seal failure. Therefore, an efficient and stable connection process is crucial to the overall operation of the high-pressure pump and directly affects the continuity and safety of production operations. Currently, some high-pressure pump connection devices use external pressure clips for connection and fixation. These clips require manual application of external force for installation, which is not only inconvenient to operate, but also prone to elastic decay or structural deformation after long-term use. Due to the lack of a design similar to a spring actively applying opposing forces, external pressure clips cannot maintain a stable clamping of the flange, which can easily lead to gaps between the flanges and cause fluid leakage. At the same time, the clips themselves may also be at risk of falling off due to uneven force, which cannot meet the requirements for long-term stable operation of high-pressure pumps. Utility Model Content

[0003] The purpose of this utility model is to provide a high-pressure pump body connection device with a simple structure and reasonable design in order to solve the above problems.

[0004] This utility model achieves the above objectives through the following technical solutions: A high-pressure pump body connection device includes a pump body, an interface pipe fixed at the interface of the pump body, a first flange fixed at the end of the interface pipe away from the pump body, and a clamping assembly provided on the outer edge of the first flange.

[0005] As a further optimization of this utility model, a second flange is provided on the outer side of the first flange, and rubber sealing rings are fixed on both sides of the inner side of the second flange. A threaded rod is fixedly passed through the surface of the second flange, and the surface of the threaded rod slides through the surface of the first flange.

[0006] As a further optimization of this utility model, a connecting pipe is provided on the side of the second flange away from the pump body, and a third flange is fixed at the end of the connecting pipe near the second flange. The surface of the third flange is sleeved through the outside of the threaded rod.

[0007] As a further optimization of this utility model, the clamping assembly includes two clamping blocks that are sleeved through the threaded rod, and each clamping block has a hexagonal groove on its surface.

[0008] As a further optimization of this utility model, each of the clamping blocks has a sliding groove inside, and a sliding block is slidably sleeved inside the sliding groove. Two metal hooks are fixed on the inner surface of each sliding groove, and a spring passing through the sliding block is provided between the opposing metal hooks.

[0009] As a further optimization of this utility model, a clamping nut with a thread that passes through the threaded rod is provided on the inner side of the hexagonal groove, and a limiting nut with a thread that passes through the threaded rod is provided on the outer side of the clamping block.

[0010] The beneficial effects of this utility model are as follows: 1. In this utility model, when the clamping assembly is installed, the tensioning clamping block causes the spring to undergo elastic deformation. When the spring contracts, it applies opposing forces to the first flange and the third flange. This force can assist in clamping the flange, causing the first flange and the third flange to close more tightly with the second flange, further improving the sealing of the connection and enhancing the overall sealing performance of the high-pressure pump body connection device.

[0011] 2. In this utility model, the clamping assembly uses the hexagonal groove of the clamping block to hold the clamping nut, and then uses the limiting nut to restrict the movement, thereby fixing the clamping nut. In this process, the hexagonal groove can stably accommodate the clamping nut, effectively preventing it from rotating due to interference from external factors, thus avoiding leakage problems caused by loose nuts and ensuring the sealing effect of the connection device.

[0014] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0015] Example: Figure 1 , Figure 2 As shown, a high-pressure pump body connection device includes a pump body 1, which provides high-pressure power to transport fluid. An interface pipe 2 is fixed at the interface of the pump body 1, and the interface pipe 2 is used to transport high-pressure fluid. A first flange 3 is fixed at the end of the interface pipe 2 away from the pump body 1. A clamping assembly 10 is provided on the outer edge of the first flange 3 to prevent the clamping nut 9 from loosening and to assist in clamping the flange. A second flange 4 is provided on the outer side of the first flange 3. A connecting pipe 7 is provided on the side of the second flange 4 away from the pump body 1. The connecting pipe 7 is used to cooperate with the interface pipe 2 to transport fluid. A third flange 8 is fixed at one end near the second flange 4. The third flange 8 is used to mate with the second flange 4 and the first flange 3. The surface of the third flange 8 is sleeved through the outside of the threaded rod 6. The second flange 4 is used to connect the first flange 3 and the third flange 8. Rubber sealing rings 5 ​​are fixed on both sides inside the second flange 4. The rubber sealing rings 5 ​​are used to prevent leakage during the operation of the high-pressure pump. A threaded rod 6 is fixed through the surface of the second flange 4. The threaded rod 6 is used to connect each flange to the clamping assembly 10. The surface of the threaded rod 6 is sleeved through the surface of the first flange 3.

[0016] like Figure 1 , Figure 3 As shown, the clamping assembly 10 includes two clamping blocks 1002 that are sleeved through the threaded rod 6. Each clamping block 1002 is used to accommodate a clamping nut 9 via a hexagonal groove 1003. The hexagonal groove 1003 is formed on the surface of each clamping block 1002 to restrict the rotation of the clamping nut 9. Each clamping block 1002 has a sliding groove inside for sliding of a sliding block 1001. A sliding block 1001 is slidably sleeved inside the sliding groove. The sliding block 1001 cooperates with a spring 1005 to extend and retract the clamping block 1002. The inner surface of each sliding groove... Two metal hooks 1004 are fixed on the surface. The metal hooks 1004 are used to fix the spring 1005. A spring 1005 is provided between the opposing metal hooks 1004 and passes through the sliding block 1001. The spring 1005 is used to retract the clamping block 1002 and apply opposing forces. A clamping nut 9 with a thread passing through the threaded rod 6 is provided on the inner side of the hexagonal groove 1003. The clamping nut 9 is used to fix the first flange 3 and the third flange 8. A limiting nut 11 with a thread passing through the threaded rod 6 is provided on the outer side of the clamping block 1002. The limiting nut 11 is used to limit the range of motion of the clamping block 1002.

[0017] It should be noted that, in the use of this high-pressure pump body 1 connecting device, the threaded rod 6 on the second flange 4 is first aligned with the holes on the first flange 3 and the third flange 8, and then they are brought together. The rubber sealing ring 5 inside the second flange 4 will be tightly connected with the interface pipe 2 and the connecting pipe 7, so that leakage will be avoided when the high-pressure pump is working.

[0018] After the docking is completed, the first flange 3 and the third flange 8 are first fixed with the clamping nut 9 to ensure a tight seal with the second flange 4. Then, the clamping block 1002 in the clamping assembly 10 is stretched, causing the spring 1005 to elastically deform and extending the length of the clamping assembly 10. The clamping assembly 10 is then fitted onto both ends of the threaded rod 6. At this point, the clamping block 1002 will contract and slide due to the deformation of the spring 1005. When the clamping block 1002 contacts the clamping nut 9, the hexagonal groove 1003 on the inner side of the clamping block 1002 will accommodate the clamping nut. 9. This makes it difficult for the clamping nut 9 to rotate under the interference of external factors, thereby preventing the loosening of the clamping nut 9 from causing leakage between the interface pipe 2 and the connecting pipe 7. At the same time, the clamping assembly 10 will also exert opposing forces on the first flange 3 and the third flange 8 due to the deformation of the spring 1005, playing an auxiliary clamping function, so that the first flange 3 and the third flange 8 can be more tightly closed with the second flange 4. Finally, the limit nut 11 is used to limit the range of motion of the clamping block 1002, thereby preventing the clamping assembly 10 from falling off the threaded rod 6 due to operational errors.

[0019] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
