Description

Technical Field

[0001] The utility model relates to the technical field of heat exchanger pressure testing, in particular to a heat exchanger pressure testing device. Background Art

[0002] A heat exchanger, also known as a heat exchanger, is a device that transfers some of the heat from a hot fluid to a cold fluid. Heat exchangers play a vital role in chemical, petroleum, power, food, and many other industrial processes. Fins in heat exchangers play a crucial role in enhancing heat transfer efficiency, improving heat dissipation, reducing flow resistance, strengthening mechanical strength, and expanding the range of applications. The design and performance of fins directly impact the performance and efficiency of the entire heat exchanger, leading to their widespread application across various industrial sectors.

[0003] At present, the existing heat exchanger has a pipe opening at the pipe box head position, and when the heat exchanger with the layered partition facing upward is subjected to a water pressure test on the pipe side, air will not be discharged from the top of the layered partition near the pipe opening side of the pipe box head, resulting in that the water pressure test pressure is difficult to reach the set value. In addition, if a destructive accident occurs in the pipe box, the loss will increase due to the compression of the air. In the related technology, a stainless steel pipe with a bent structure is provided at the pipe opening at the pipe box head position of the heat exchanger. The end position of the stainless steel pipe can reach the top of the layered partition, effectively discharging the accumulated air. When the pressure test tool is used, the pressure test boosting time is greatly reduced, and the loss after a destructive accident occurs in the pipe box is reduced. However, the bent stainless steel pipe is inconvenient to insert into the pipe box head and inconvenient to remove, which leads to certain limitations. Utility Model Content

[0037] First, the stainless steel pipe is bent through the structure so that the end of the steel pipe is at the top of the inclined structure layered partition. When the heat exchanger tube box is subjected to a water pressure test, the stainless steel pipe is controlled by the control valve so that the pressure tooling body can discharge the air that is difficult to discharge from the top of the inclined structure layered partition, thereby reducing the pressure test boost time. The stainless steel pipe is fixed in the mounting hole seat at the tube box head by the flange cover.

[0038] In the related art, air in the heat exchanger is difficult to discharge. Generally, a stainless steel tube with a bent structure is set at the pipe mouth of the heat exchanger tube box head. The end of the stainless steel tube can reach the top of the layered partition to effectively discharge the accumulated air. When using the pressure test tooling, the pressure test boosting time is greatly reduced, and the loss after a destructive accident in the tube box is reduced. However, the bent stainless steel tube is inconvenient to insert into the tube box head and is inconvenient to remove, which leads to certain limitations.

[0039] In order to solve the problems in the related art to a certain extent, the embodiment of the present application provides a heat exchanger pressurizing device. When the heat exchanger needs to be pressurized, it is only necessary to insert the sleeve 21 into the pipe box head 12, and then install the flange cover 14 on the mounting hole seat 13. Then, by pulling the insertion rod 27, disengage from the fixing hole 29, the movement of the insertion rod 27 drives the spring 28 to stretch, and then by pulling the pull rod 24, the rotation of the connecting pipe 23 is driven by the rotating rod 25 and the adjusting rod 26. The connecting pipe 23 is rotated by the bending of the bellows 22. When the upper end of the connecting pipe 23 reaches the top of the layered partition 17, the insertion rod 27 is released, and the rebound force of the spring 28 drives the insertion rod 27 to automatically move back and insert it into the corresponding fixing hole 29 for fixation, thereby effectively expelling the accumulated air. When the processing is completed, the reverse operation restores the bellows 22 and the connecting pipe 23 to the horizontal state, thereby facilitating removal.

[0040] The present application is described below with reference to specific embodiments and with reference to the accompanying drawings:

[0041] Combine Figure 1-Figure 5 The embodiment of the present application provides a heat exchanger pressure device, including a main body component 1; the main body component 1 includes: a heat exchanger pipe box 11, on which a pipe box head 12 is provided; a mounting hole seat 13, which is provided on the pipe box head 12; a flange cover 14, which is provided on the mounting hole seat 13; a stainless steel pipe 15, which is provided on the flange cover 14; a control valve 16, which is provided on the stainless steel pipe 15; a layered partition 17, which is provided on the inner wall of the heat exchanger pipe box 11; an adjustment component 2 is provided on the stainless steel pipe 15, and the adjustment component 2 includes: a sleeve 21, which is provided on the stainless steel pipe 15; a bellows 22, which is provided on the stainless steel pipe 15; a connecting pipe 23 is provided on the bellows 22; a pull rod 24 is slidably connected to the flange cover 14, and the pull rod 24 and the sleeve 21 are slidably connected; a rotating rod 25 is rotationally connected to the pull rod 24; an adjusting rod 26 is fixedly connected to the rotating rod 25, and the adjusting rod 26 and the connecting pipe 23 are rotationally connected; an insertion rod 27 is slidably connected to the flange cover 14; a spring 28 is sleeved on the insertion rod 27, and the two ends of the spring 28 are respectively fixedly connected to the flange cover 14 and the insertion rod 27; a fixing hole 29 is opened on the pull rod 24, and the insertion rod 27 is inserted into the fixing hole 29.

[0042] By setting a stainless steel tube 15 with a bent structure at the pipe mouth of the heat exchanger tube box head 12, the end position of the stainless steel tube 15 can reach the top of the layered partition 17, effectively discharging the accumulated air, and when using the pressure test tool, the pressure test boost time is greatly reduced, and at the same time, the loss after a destructive accident of the heat exchanger tube box 11 is reduced. However, the bent stainless steel tube 15 is inconvenient to insert into the tube box head and inconvenient to remove, which leads to certain limitations. Therefore, when the heat exchanger needs to be pressurized, it is only necessary to insert the sleeve 21 into the tube box head 12, and then install the flange cover 14 on the mounting hole seat 13, and then Then, the insertion rod 27 is pulled out of the fixing hole 29, and the movement of the insertion rod 27 drives the spring 28 to be stretched. Then, the pull rod 24 is pulled with the help of the rotating rod 25 and the adjusting rod 26 to drive the rotation of the connecting pipe 23. The connecting pipe 23 is rotated by the bending of the bellows 22. When the upper end of the connecting pipe 23 reaches the top of the layered partition 17, the insertion rod 27 is released, and the rebound force of the spring 28 drives the insertion rod 27 to automatically move back and insert it into the corresponding fixing hole 29 for fixation, thereby effectively expelling the accumulated air. When the processing is completed, the reverse operation is performed to restore the bellows 22 and the connecting pipe 23 to a horizontal state, thereby facilitating removal.

[0043] In some embodiments, a positioning assembly 3 is provided on the flange cover 14, and the positioning assembly 3 includes: a positioning rod 31, which is provided on the flange cover 14; a positioning groove 32, which is opened on the mounting hole seat 13, and the positioning rod 31 is inserted into the positioning groove 32. When the flange cover 14 is installed on the mounting hole seat 13, the two positioning rods 31 on one side of the flange cover 14 are aligned and inserted into the two positioning grooves on one side of the mounting hole seat 13 for positioning, thereby avoiding the device on the flange cover 14 from being offset.

[0044] In some embodiments, a precision component 4 is provided on the flange cover 14, and the precision component 4 includes: a pointer 41, which is provided on the flange cover 14; a scale 42, which is provided on the pull rod 24. When the angle of the connecting pipe 23 needs to be adjusted, the precise angle of deflection of the connecting pipe 23 can be conveniently understood by observing the scale 42 corresponding to the pointer 41.

[0045] In some embodiments, a limit plate 5 is provided on one side of the sleeve 21 to facilitate the connection pipe 23 to quickly and accurately return to a horizontal position.

[0046] In some embodiments, the arc surface of the rotating rod 25 is covered with a coil spring 6, and the two ends of the coil spring 6 are respectively fixedly connected to the pull rod 24 and the adjusting rod 26. The movement of the pull rod 24 drives the rotation of the rotating rod 25 and the adjusting rod 26, thereby driving the compression of the coil spring 6. When the reverse operation is performed to restore the connecting tube 23 to the horizontal, the rebound force of the coil spring 6 drives the connecting tube 23 to move back quickly.

[0047] In some embodiments, a guide block 7 is provided at one end of the insertion rod 27. When the insertion rod 27 is moved and inserted into the fixing hole 29 for fixation, the guide block 7 is tapered, so that the insertion rod 27 can be inserted into the fixing hole 29 quickly and accurately.

[0048] In some embodiments, a handle 8 is provided at one end of the pull rod 24. When the pull rod 24 needs to be moved, the pull rod 24 is driven to move by moving the handle 8, which is convenient and labor-saving to operate.

[0049] In some embodiments, a sealing ring 9 is provided on the inner wall of the sleeve 21, and the sealing ring 9 is slidably connected to the pull rod 24 to ensure good sealing between the sleeve 21 and the pipe box head 12 during the movement of the pull rod 24.

Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art can combine and combine different embodiments or examples described in this specification.

[0051] In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the fact that ordinary technicians in this field can implement them. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by this application.
