Description

Technical Field

[0001] This utility model relates to the field of sealing technology for hot water exchange pumps, and in particular to a detachable multi-stage sealing hot water exchange pump device. Background Technology

[0002] With the development of industrial technology, hot water pumps play a vital role in various fluid transport systems. In these applications, as a key device for achieving heat exchange, the sealing performance of the hot water pump directly affects the operating efficiency, safety and service life of the equipment. Ensuring the sealing reliability of the pump and its connecting pipe interfaces is of utmost importance. Currently, existing hot water pump sealing devices typically employ a single sealing structure or a simple multi-stage sealing design in practical applications. In the long-term operation of a single sealing structure, if the seals experience wear, aging, or fatigue failure, fluid leakage can easily occur, affecting the normal operation of the pump and even causing safety accidents.

[0003] In some existing technologies, hot water pumps often use a single sealing structure, which means that when the seal wears out, it needs to be adjusted or replaced immediately, which is quite troublesome. Moreover, existing sealing devices cannot actively adjust according to the wear of the seal during operation. Frequent replacement of seals will consume a lot of time and labor costs, and may also seriously affect the maintenance efficiency of the equipment and the continuity of production. Utility Model Content

[0004] The main objective of this invention is to provide a detachable multi-stage sealed hot water exchange pump device, which can effectively solve the problems mentioned above. In some existing technologies, hot water exchange pumps mostly use a single sealing structure, which means that when the seal wears out, it needs to be adjusted or replaced immediately, which is quite troublesome. Moreover, existing sealing devices cannot actively adjust according to the wear of the seal during operation. Frequent replacement of the seal will consume a lot of time and manpower, and may also seriously affect the maintenance efficiency and production continuity of the equipment.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A detachable multi-stage sealed hot water exchange pump device includes a hot water exchange pump body. Pipes 1 are symmetrically installed on the left and right ends of the hot water exchange pump body. Pipes 2 are provided on opposite ends of the two pipes 1. Flange mechanisms are installed on opposite sides of the pipes 1 and pipes 2 located on the same side. Sealing mechanisms are installed on the inner surfaces of the two flange mechanisms.

[0006] Preferably, both flange mechanisms include two flange bodies, and mounting grooves are provided on opposite sides of the two flange bodies located on the same side.

[0007] Preferably, a second mounting groove is symmetrically arranged on the outer circumference of the flange body near the first mounting groove.

[0008] Preferably, the inner surfaces of the two mounting slots located on the same side are circumferentially symmetrically connected with fixing bolts.

[0009] Preferably, the first and second pipes located on the same side are installed and fixed together by a flange mechanism, and the two flange bodies located on the same side are installed and fixed together by fixing bolts.

[0010] Preferably, both sealing mechanisms include two primary sealing ring grooves. The primary sealing ring grooves and primary sealing rings located on the same side are respectively fixedly connected to the opposite sides of the two mounting grooves. The right end of the primary sealing ring is engaged with the inner surface of the primary sealing ring groove.

[0011] Preferably, the inner surfaces of several mounting grooves II located on the same side are slidably connected to push blocks, the right ends of several push blocks located on the left side of the same side are jointly fixedly connected to a secondary sealing ring II, and the left ends of several push blocks located on the right side of the same side are jointly fixedly connected to a secondary sealing ring groove II.

[0012] Preferably, the right end of the second secondary sealing ring located on the same side is engaged with the inner surface of the second secondary sealing ring groove. The opposite ends of several push blocks located on the same side are fixedly connected with rotating sleeves. A rotating round block is rotatably connected to the inner surface of the rotating sleeve. A threaded rod is fixedly connected to the middle of the rotating round block on the side away from the flange mechanism. An adjusting handle is threadedly connected to the end of the threaded rod away from the flange mechanism.

[0013] Preferably, the outer surfaces of several threaded rods located on the same side and in the same part are threadedly connected to threaded sleeve seats, and the opposite sides of several threaded sleeve seats located on the same side and in the same part are jointly fixedly connected to a retaining ring.

[0014] Preferably, the inner sides of the two fixing rings located on the same side are fixedly connected to the outer surfaces of pipe one and pipe two, respectively.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. This device utilizes a primary sealing ring groove and a secondary sealing ring groove. The sealing mechanism employs multiple sealing layers, with each sealing ring creating a progressive barrier. Even if one sealing layer fails, the others can still function, significantly improving sealing reliability. The multi-stage sealing design reduces wear and fatigue of individual seals, thus extending the service life of the sealing device. By preventing leakage, it ensures smooth fluid flow within the pump, thereby improving pump operating efficiency and reducing energy waste.

[0016] 2. This device, through its designed push block, eliminates the need for immediate pipe disassembly for replacement or adjustment of traditional worn seals. Instead, this design allows operators to directly adjust the relative position of the seals from the outside by rotating the threaded rod, greatly simplifying the maintenance process and saving time and labor costs. By rotating the threaded rod, the secondary sealing ring and the secondary sealing groove can be moved to opposite sides without disassembling pipes one and two. By adjusting the distance between the secondary sealing ring and the secondary sealing groove from the outside, the tightness of the secondary seal can be restored or maintained through active adjustment, effectively preventing leakage caused by wear and ensuring stable operation of the equipment under expected parameters.

[0019] 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.

[0020] Example 1, as Figure 1 As shown, a detachable multi-stage sealed hot water pump device includes a hot water pump body 1. Pipes 1 2 are symmetrically installed on the left and right ends of the hot water pump body 1. Pipes 2 3 are provided on opposite ends of the two pipes 1 2. Flange mechanisms 4 are installed on opposite sides of pipes 1 2 and pipes 2 3 located on the same side. Sealing mechanisms 5 are installed on the inner surfaces of the two flange mechanisms 4.

[0021] In this embodiment, the flange mechanism 4 is installed between pipe 2 and pipe 3. When the device is working, the hot water pump body 1 drives the internal fluid circulation. The left and right ends of the pump body 1 are connected to pipe 2 respectively. Pipe 2 is connected to pipe 3 through the flange mechanism 4 to form a complete fluid passage. The flange mechanism 4 firmly connects pipe 2, pipe 3 and the two flange bodies 401 together with fixing bolts 404. The sealing mechanism 5 installed on its inner surface adopts a multi-stage sealing structure to achieve the effect of preventing fluid leakage.

[0022] For details, please refer to Figure 1 , Figure 2 and Figure 4 In this embodiment, each of the two flange mechanisms 4 includes two flange bodies 401. The two flange bodies 401 located on the same side are provided with mounting groove 1 402 on opposite sides. The flange body 401 is provided with mounting groove 2 403 symmetrically arranged on the outer circumference near mounting groove 1 402. The inner surfaces of the two mounting groove 2 403 located on the same side are symmetrically connected with fixing bolts 404 by thread. Further reference Figure 1 , Figure 2 and Figure 4 In this embodiment, pipe 2 and pipe 3 located on the same side are installed and fixed by flange mechanism 4, and two flange bodies 401 located on the same side are installed and fixed by fixing bolts 404.

[0023] Example 2: Based on Example 1, this example adds a sealing mechanism 5 for multi-stage sealing at the connection between pipe 1 2 and pipe 2 3. By setting the sealing mechanism 5, the wear and fatigue of a single sealing element can be reduced through multi-stage sealing design, thereby extending the service life of the sealing device.

[0024] For details, please refer to Figure 2 , Figure 3 , Figure 4 and Figure 5 In this embodiment, both sealing mechanisms 5 include two primary sealing ring grooves 501. The primary sealing ring grooves 501 and primary sealing rings 502 located on the same side are respectively fixedly connected to the opposite sides of the two mounting grooves 402. The right end of the primary sealing ring 502 is engaged with the inner surface of the primary sealing ring groove 501. Further reference Figure 2 , Figure 3 , Figure 4 and Figure 5In this embodiment, the inner surfaces of several mounting grooves 403 on the same side are slidably connected to push blocks 505, the right ends of several push blocks 505 on the left side of the same side are fixedly connected to secondary sealing rings 503, and the left ends of several push blocks 505 on the right side of the same side are fixedly connected to secondary sealing ring grooves 504. Further reference Figure 2 , Figure 3 and Figure 5 In this embodiment, the right end of the secondary sealing ring 503 located on the same side is engaged with the inner surface of the secondary sealing ring groove 504. The opposite ends of several push blocks 505 located on the same side are fixedly connected to rotating sleeves 506. The inner surface of the rotating sleeve 506 is rotatably connected to a rotating block 507. A threaded rod 508 is fixedly connected to the middle of the rotating block 507 on the side away from the flange mechanism 4. An adjusting handle 509 is threadedly connected to the end of the threaded rod 508 away from the flange mechanism 4. Further reference Figure 2 , Figure 3 and Figure 5 In this embodiment, the outer surfaces of several threaded rods 508 located on the same side and in the same part are threadedly connected to threaded sleeve seats 510, and the opposite sides of several threaded sleeve seats 510 located on the same side and in the same part are fixedly connected to fixing rings 511, and the inner sides of two fixing rings 511 located on the same side are respectively fixedly connected to the outer surfaces of pipe 1 2 and pipe 2 3. The sealing mechanism 5 adopts a multi-stage sealing design, including a primary seal consisting of a primary sealing ring groove 501 and a primary sealing ring 502, and a secondary seal consisting of a secondary sealing ring 503 and a secondary sealing ring groove 504. In the working state, each sealing ring groove is provided with a corresponding sealing ring. Under the action of pre-tightening force and fluid pressure, these sealing rings are tightly fitted between the corresponding sealing ring and sealing ring groove, forming a sealing structure with step-by-step blocking. The innermost primary seal is prone to wear due to long-term use or other reasons, resulting in poor sealing performance and slight leakage. The secondary seal can still provide effective protection to ensure that fluid does not leak out. After the device has been running for a long time, the connection between the secondary sealing ring 2 503 and the secondary sealing ring groove 2 504 will wear, resulting in an increased sealing gap and a decrease in sealing effect. At this time, there is no need to disassemble pipe 1 2 and pipe 2 3. The operator only needs to operate the adjustment handle 509 from the outside. Turning the handle 509 will drive the threaded rod 508 to rotate. Since the threaded rod 508 is rotatably connected to the inside of the rotating sleeve 506 through the rotating block 507, and the push block 505 slides left and right in the mounting groove 2 403, the rotation of the threaded rod 508 will drive the push block 505 on the same side to move in the opposite or opposite direction. When it is necessary to repair worn areas, by rotating in a specific direction, the secondary sealing ring 503 connecting the push block 505 and the secondary sealing ring groove 504 connecting the right push block 505 can be brought closer together, reducing the distance between them. This allows for a greater pre-tightening force to be applied to the worn sealing ring, restoring or maintaining its sealing performance and reducing the hassle of frequently replacing the secondary sealing ring 503 and the secondary sealing ring groove 504. When it is necessary to replace the secondary sealing ring 503 and the secondary sealing ring groove 504, disassemble pipe 1 2 and pipe 2 3, remove the damaged secondary sealing ring 503 and the secondary sealing ring groove 504, and pass the new secondary sealing ring 503 and the secondary sealing ring groove 504, as well as the structure of the threaded rod 508 fixed on its outer side, through the inner side of several mounting grooves 403 for installation and fixation. Then, the threaded rod 508 and the adjusting handle 509 are threaded together. The overall operation is simple and convenient. By designing the primary sealing ring groove 501 and the secondary sealing ring groove 504, the sealing mechanism 5 sets multiple sealing layers, with each sealing ring forming a step-by-step barrier. Even if one sealing layer fails, the other sealing layers can still function, thus significantly improving the reliability of the seal. The multi-stage sealing design reduces the wear and fatigue of individual sealing elements, thereby extending the service life of the sealing device. By preventing leakage, it ensures smooth flow of fluid inside the pump, thereby improving the operating efficiency of the pump and reducing energy waste. With the designed push block 505, traditional seals often require immediate pipe disassembly for replacement or adjustment after wear. This design allows operators to adjust the relative position of the seals directly from the outside by rotating the threaded rod 508, greatly simplifying the maintenance process and saving time and labor costs. By rotating the threaded rod 508, the secondary sealing ring 503 and the secondary sealing ring groove 504 can be moved to opposite sides without disassembling pipes 1-2 and 2-3. By adjusting the distance between the secondary sealing ring 503 and the secondary sealing ring groove 504 from the outside, the tightness of the secondary seal can be restored or maintained through active adjustment, effectively preventing leakage caused by wear and ensuring stable operation of the equipment under expected parameters.
