Description

Technical Field

[0001] The utility model relates to the field of pipeline connection structures, in particular to a pipe body connection structure for a buffer tank. Background Art

[0002] Buffer tanks play a vital role in a variety of fields, primarily serving to buffer system pressure fluctuations and ensure smoother operation. They balance pressure differences within the system by absorbing or releasing gas, ensuring system stability. In water supply equipment and central air conditioning systems, buffer tanks regulate water pressure, preventing frequent pump activation due to pressure fluctuations, thereby protecting equipment and extending its service life. When the water pressure within the system fluctuates slightly, the automatic expansion and contraction of the buffer tank's air bladder cushions the pressure fluctuation, effectively eliminating water hammer and protecting pipes and equipment from impact.

[0003] The buffer tank is usually placed on the side with a pipe connection port for connecting pipelines, but the conventional method is direct flange connection, which requires manual operation to tighten multiple bolts to achieve fixation. Although the sealing can be ensured, the bolts on the flange are set parallel to the axial direction of the pipe and the bolts are close to the outer wall of the pipe. There are limitations in disassembling and assembling the bolts with tools such as wrenches. Disassembly and assembly during emergency maintenance is time-consuming and labor-intensive, affecting efficiency.

[0004] Therefore, it is necessary to propose a pipe connection structure for a buffer tank to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0027] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0028] like Figure 1-7 As shown, a pipe connection structure for a buffer tank includes a buffer tank 1, a second pipe 3 provided on the side of the buffer tank 1, and a first pipe 2 connected to the second pipe 3. A third pipe 4 is provided between the first pipe 2 and the second pipe 3. One end of the third pipe 4 is connected to the second pipe 3 via a flange 5, and the other end is connected to the first pipe 2 via a clamping structure.

[0029] As an embodiment, the clamping structure includes a locking sleeve 6 arranged at one end of the third pipe 4 close to the first pipe 2, and a flange 8 is provided at one end of the first pipe 2 close to the third pipe 4. The flange 8 is annular, and a fixed arm 7 is evenly arranged around the outside of the flange 8. A positioning groove 16 corresponding to the fixed arm 7 is evenly arranged around the outside of the locking sleeve 6. The end of the fixed arm 7 away from the first pipe 2 is arc-shaped, and the fixed arm 7 is plugged into the positioning groove 16. The inner wall of the end of the positioning groove 16 is provided with a clamping groove 17. The end of the fixed arm 7 away from the first pipe 2 is penetrated and fixed with a cylinder 19, and the cylinder 19 is connected to the first pipe 2. The axial direction of the cylinder 19 is perpendicular, and one end of the cylinder 19 close to the axis of the first pipe 2 is movably connected along the axial direction of the cylinder 19 with a block 22 for engaging with the card slot 17, and the end of the block 22 close to the axis of the first pipe 2 is an inclined surface, and the end of the cylinder 19 away from the axis of the first pipe 2 is threadedly connected to a bolt 20 perpendicular to the axial direction of the first pipe 2, and a slider 23 located between the bolt 20 and the block 22 is slidably connected to the inside of the cylinder 19, and one end of the bolt 20 is rotatably connected to the end of the slider 23 away from the first pipe 2, and a second elastic member 21 is provided between the block 22 and the side of the slider 23 away from the bolt 20.

[0030] It also includes a sealing assembly, which includes a sealing sleeve 9 fixedly arranged on the end of the third pipe 4 close to the first pipe 2 and located on the inner side of the locking sleeve 6, a sealing groove 12 is provided on the side of the sealing sleeve 9 close to the first pipe 2, a sealing ring 14 is provided on the inner side of the sealing groove 12, and an insert ring 24 for plugging and cooperating with the sealing groove 12 is provided on the side of the first pipe 2 close to the third pipe 4, and the end of the insert ring 24 away from the first pipe 2 is used to abut and cooperate with the sealing ring 14, a slip ring 13 is connected to the inner side of the sealing groove 12 along the axial sliding of the sealing sleeve 9, and the sealing ring 14 is fixedly connected to the side of the slip ring 13, and a first elastic member 15 is evenly arranged around the inner wall of the slip ring 13 and the first elastic member 15 is in a contracted state when the clamping block 22 is engaged with the clamping groove 17.

[0031] In order to filter the fluid, a positioning ring 11 is fixedly installed on the inner side of the sealing sleeve 9 and the inner side of the insert ring 24. A filter mesh 10 with a diameter matching the diameter of the positioning ring 11 is arranged between the two positioning rings 11, and an annular collection groove 18 is provided at the adjacent end of the two positioning rings 11.

[0032] When the first pipe 2 and the third pipe 4 need to be installed during use, the fixing arm 7 is aligned with the positioning groove 16, and then docked. The fixing arm 7 enters the positioning groove 16, and then one end of the insert ring 24 enters the sealing groove 12. Then the insert ring 24 contacts the sealing ring 14, and the first elastic member 15 is compressed by the sliding ring 13. The first elastic member 15 generates a reverse force so that the sealing ring 14 is in close contact with the end of the insert ring 24, thereby increasing the sealing performance. Then, when the clamping block 22 is aligned with the clamping groove 17, the second elastic member 21 is reset, and the clamping block 22 is clamped with the clamping groove 17, thereby completing the fixation, and the third pipe 4 is fixed. The other end can be directly connected to the first pipe 2 on one side of the buffer tank 1 through the flange 5. When disassembling, the bolt 20 is tightened with a wrench. The bolt 20 drives the second elastic member 21 to gradually reset through the slider 23. After resetting, the second elastic member 21 will drive the block 22 to move, and then the block 22 will be disengaged from the slot 17. Then the first pipe 2 and the third pipe 4 can be separated. The bolt 20 is operated along the radial direction of the first pipe 2, which is convenient and easy. After disassembly, the filter screen 10 can be directly taken out, and the filtered impurities can be stored in the collection tanks 18 on both sides of the filter screen 10.
