Description

Technical Field

[0001] This utility model relates to the field of pump body equipment technology, and in particular to a water supply pump interface structure. Background Technology

[0002] Feedwater pumps play a crucial role in boiler systems, primarily functioning to circulate water, maintain pressure, and ensure system stability. The connection between the feedwater pump and pipeline is typically rigid (e.g., flange connection or welding). This structure requires strict alignment and sufficient clearance between the pump and pipeline installation positions. However, in actual engineering projects, space constraints, construction errors, or design deviations often result in insufficient clearance or angular misalignment. This necessitates repeated adjustments to the pump position, pipe cutting, or custom-made connectors during installation, consuming significant manpower and resources. Furthermore, forced installation can lead to stress concentration at the connection points, potentially causing loosening of the interface, seal failure, or even pipeline rupture during long-term operation. Therefore, a feedwater pump interface structure is proposed to address these issues. Utility Model Content

[0003] The purpose of this utility model is to address the aforementioned shortcomings by providing a water pump interface structure that can be adapted to different spacings of water pumps and pipelines for installation and use.

[0004] To solve the above technical problems, this utility model adopts the following technical solution: a water pump interface structure, comprising:

[0005] The connecting pipe includes a first pipe and a second pipe that is telescopic, slidable and rotatable and disposed therein. The first pipe and the second pipe are dynamically sealed together, and threaded grooves are provided on their opposite sides.

[0006] The mounting components are rotatably mounted on the connecting pipe body;

[0007] A locking component is provided on the connecting tube and the mounting component, which can limit the first tube and the second tube after they have rotated and moved to the corresponding positions.

[0008] Furthermore, the installation assembly includes a telescopic platform, which is rotatably connected to the side of the first pipe body near the second pipe body, and the telescopic end of the telescopic platform is provided with an installation plate.

[0009] Furthermore, the locking assembly includes ratchet wheels rotatably disposed on both sides of the telescopic platform. One of the ratchet wheels is disposed on the side of the first tube body near the telescopic platform, and the ratchet wheel can be rotated when the first tube body rotates. A guide bar is disposed on the second tube body, and the other ratchet wheel is sleeved on the second tube body, and a groove for accommodating the guide bar is formed on its inner wall. The second tube body can be rotated when it rotates, and a pawl is rotatably disposed on the telescopic platform. The pawl can abut against each of the ratchet wheels, so that the first tube body and the second tube body can only rotate in one of the directions.

[0010] Furthermore, a sealing component is provided on the connecting pipe body, which can seal when the connecting pipe body is connected to the water pump interface and the pipe interface.

[0011] Furthermore, the sealing assembly includes a first sealing ring and a second sealing ring. The first sealing ring has an annular groove, and the second sealing ring has an annular protrusion that is annular and fits the annular groove. The first sealing ring is disposed on the connecting pipe body, and the second sealing ring is disposed at the water pump interface or the pipe interface.

[0012] The beneficial effects of this utility model are reflected in:

[0013] In this invention, threads are also provided at the water pump and pipe interface. By stretching the length of the first and second pipes, the sides of the pipes that are far apart from each other can be brought close to the water pump and pipe interface. Through the interlocking of the threads, the first and second pipes can be screwed together and fixed at the water pump and pipe interface. This method can adjust the length to adapt to the installation distance of the water pump and pipe under different conditions, thus facilitating practical use. Attached Figure Description

[0022] 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 a part of the embodiments of the present utility model, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0023] Please see Figure 1-4 This utility model discloses a water pump interface structure, including a connecting pipe body 1, which includes a first pipe body 11 and a second pipe body 12 that is telescopically sliding and rotatably installed inside it. The first pipe body 11 and the second pipe body 12 are dynamically sealed together, and threaded grooves 13 are provided on their opposite sides. In practice, the threaded grooves 13 can be opened on the inner wall of the corresponding pipe body or on the outer wall of the corresponding pipe body.

[0024] In one embodiment, the system further includes an installation component 2, which is rotatably mounted on the connecting tube 1. The connecting tube 1 and the installation component 2 are also provided with a locking component, which can limit the first tube 11 or the second tube 12 after it has rotated and moved to the corresponding position.

[0025] In practice, threads are also provided at the water pump and pipe interface. By stretching the length of the first pipe body 11 and the second pipe body 12, the side of each pipe body that is far apart from each other can be brought close to the water pump and pipe interface. Through the interlocking of the threads, the first pipe body 11 and the second pipe body 12 can be screwed and fixed at the water pump and pipe interface. This method can adjust the corresponding length to adapt to the installation distance of the water pump and pipe under different conditions, thus facilitating actual use.

[0026] In addition, the mounting component 2 can be fixed to the corresponding mounting location, such as the base or the ground. After the length of the first tube 11 or the second tube 12 is adjusted, the locking component is adjusted to limit the first tube 11 and the second tube 12, thereby ensuring that the structure has good structural stability during use.

[0027] In one embodiment, the mounting assembly 2 includes a telescopic platform 21, which is rotatably connected to the side of the first tube 11 near the second tube 12. An mounting plate 22 is installed at the telescopic end of the telescopic platform 21, and the mounting plate 22 has a through hole 25.

[0028] With this design, by adjusting the moving end of the telescopic platform 21, the mounting plate 22 can be brought close to and contacted with the corresponding mounting location. Then, by installing bolts at the through holes 25, the mounting plate 22 can be fixed to the corresponding mounting location.

[0029] In one embodiment, the locking assembly includes ratchet 23 rotatably mounted on both sides of the telescopic platform 21. One ratchet 23 is mounted on the side of the first tube 11 near the telescopic platform 21, and the ratchet 23 can be rotated when the first tube 11 rotates. A guide bar 14 is mounted on the second tube 12, and another ratchet 23 is sleeved on the second tube 12. A groove for accommodating the guide bar 14 is provided on the inner wall of the second tube 12, and the ratchet 23 can be rotated when the second tube 12 rotates. A pawl 24 is also rotatably mounted on the telescopic platform 21, and the pawl 24 can abut against each ratchet 23, so that the first tube 11 and the second tube 12 can only rotate in one direction.

[0030] In practice, when the first pipe body 11 or the second pipe body 12 moves and approaches the corresponding water pump or pipeline, it is connected to it by threads. During the rotational installation process, the corresponding ratchet 23 will also rotate. At this time, the pawl 24 will not jam the ratchet 23. After installation, the ratchet 23 cannot continue to rotate in that direction, and the pawl 24 will jam the ratchet 23, preventing it from rotating in another direction. Therefore, it can ensure that the first pipe body 11 or the second pipe body 12 is very stable after being connected to the corresponding water pump or pipeline. When disassembly is required, the operator needs to manually rotate the pawl 24 to separate it from the ratchet 23 before the ratchet 23, the first pipe body 11 or the second pipe body 12 can be rotated. In addition, when the second pipe body 12 extends or retracts, it cooperates with the guide strip 14 and the groove to prevent the ratchet 23 from being moved along with it, and it can rotate synchronously.

[0031] In one embodiment, a sealing component 3 is provided on the connecting pipe body 1.

[0032] With this design, the sealing component 3 can seal when the connecting pipe body 1 is connected to the water pump interface and the pipe interface, thereby preventing leakage.

[0033] In one embodiment, the sealing assembly 3 includes a first sealing ring 31 and a second sealing ring 32. The first sealing ring 31 has an annular groove, and the second sealing ring 32 has an annular protrusion that is annular and fits the annular groove. The first sealing ring 31 is installed on the connecting pipe body 1, and the second sealing ring 32 is installed at the water pump interface or the pipe interface.

[0034] In specific implementation, the first sealing ring 31 can be installed on the side of the first pipe body 11 and the second pipe body 12 that are far apart from each other. When the first pipe body 11 and the second pipe body 12 are installed at the water pump and pipe interface, the first sealing ring 31 and the second sealing ring 32 fit together, thereby improving the sealing performance of their connection.

[0035] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0036] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0037] Additionally, "multiple" refers to two or more.

[0038] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
