Description

Technical Field

[0001] The utility model belongs to the technical field of tube plates, in particular to an anti-deformation tube plate. Background Art

[0002] Tube sheet is a round steel plate with holes slightly larger than the outer diameter of the tube drilled on it. It is a round steel that fixes the tube and seals the medium in the heat exchanger. The tube is penetrated and welded to fix it. Tube sheet is widely used in shell-and-tube heat exchangers, boilers, pressure vessels, steam turbines, large central air conditioners and other industries.

[0003] At present, some pipelines are welded in the holes on the tube sheet. When the liquid flows too fast in the pipeline, it will produce impact force on the tube sheet, causing resonance between the tube sheet and the pipeline. Long-term vibration will not only lead to a decrease in the sealing of the connection between the tube sheet and the pipeline, but also cause deformation of the tube sheet body. Utility Model Content

[0004] In order to overcome the above defects, the utility model provides an anti-deformation tube sheet, which solves the problem that when the liquid flows too fast in the pipeline, it will generate impact force on the tube sheet, resulting in reduced sealing of the connection between the tube sheet and the pipeline, and causing deformation of the tube sheet body.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a deformation-resistant tube sheet, comprising a tube sheet body, a plurality of through holes are provided on the tube sheet body, a protective outer ring is slidably mounted on the tube sheet body, a clamping block is connected to the protective outer ring, the protective outer ring is connected to a fixing frame through the clamping block, a buffer mechanism is connected to the inside of the protective outer ring, a damper is connected to the inside of the protective outer ring, one end of the buffer mechanism and the damper are both connected to the inner wall of the tube sheet body, a shock-absorbing spring is sleeved on the damper, one end of the shock-absorbing spring is connected to the inner wall of the tube sheet body, and the other end of the shock-absorbing spring is connected to the inner wall of the protective outer ring, a clamping groove is provided on the fixing frame, and a second threaded hole is provided on the fixing frame.

[0006] As a further solution of the utility model: the buffer mechanism includes a hollow rod, a moving rod is slidably connected inside the hollow rod, and a buffer ball is connected to the inside of the hollow rod at one end of the moving rod extending into the hollow rod.

[0007] As a further solution of the utility model: a reinforcing ring is connected to the inner wall of the tube plate body, a reinforcing rib plate is connected to the inner wall of the tube plate body, there are two reinforcing rib plates which are cross-connected together, and the reinforcing rib plates and the reinforcing ring are welded to each other.

[0008] As a further solution of the utility model: there are four clamping blocks in total and they are symmetrical about the axis of the protective outer ring. The clamping blocks and the clamping slots are interlocked with each other, and first threaded holes are opened on the clamping blocks and in the clamping slots. Bolts are threadedly connected in the first threaded holes.

[0009] As a further solution of the utility model: a buffer ring is connected to the contact point between the outer wall of the tube plate body and the inner wall of the protective outer ring, a total of six dampers are distributed inside the protective outer ring in a centrally symmetrical manner about the axis of the protective outer ring, and the buffer mechanism is arranged between two dampers.

[0010] As a further solution of the utility model: a ceramic anti-corrosion coating is provided on the inner wall of the through hole, and a groove is opened in the through hole.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. The anti-deformation tube sheet is provided with a tube sheet body, a protective outer ring, a damper, a shock absorbing spring and a buffer mechanism. When the flow rate of the liquid in the pipeline is too fast, the tube sheet body will move toward the side of the protective outer ring, so that the tube sheet body can squeeze the damper and the shock absorbing spring, and the impact force generated by the vibration is buffered by compressing the shock absorbing spring, and the damper can absorb and weaken the vibration. At the same time, the buffer mechanism will also be squeezed by the tube sheet body, so that the buffer ball at one end of the moving rod and the buffer ball inside the hollow rod collide and compress with each other, thereby buffering the impact force, reducing the impact on the tube sheet body, and avoiding large deformation of the tube sheet body.

[0013] 2. The anti-deformation tube sheet is provided with a reinforcing ring, a reinforcing rib plate, a clamping block, a clamping block, a bolt and a first threaded hole. The two reinforcing rib plates are crossed with each other and welded with the reinforcing ring, so that the reinforcing rib plate and the reinforcing ring form multiple stress-bearing areas inside the tube sheet body, thereby preventing the tube sheet body from being greatly deformed when subjected to impact force. Through the interlocking connection of the clamping block and the clamping groove, the staff can quickly install the protective outer ring together with the tube sheet body on the fixing frame, and then screw the bolt into the first threaded hole to reinforce the connection and prevent the tube sheet body from falling due to the impact force generated by vibration.

DETAILED DESCRIPTION

[0020] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0021] like Figure 1-5 As shown, the utility model provides a technical solution: an anti-deformation tube sheet, including a tube sheet body 1, a plurality of through holes 2 are opened on the tube sheet body 1, a ceramic anti-corrosion coating 16 is arranged on the inner wall of the through hole 2, and a groove 17 is opened in the through hole 2. The ceramic anti-corrosion coating 16 improves the corrosion resistance of the through hole 2 and slows down the aging speed of the through hole 2. When the pipeline is welded, the tube sheet will fit with the groove 17 inside the through hole 2, thereby improving the adhesion between the pipeline and the through hole 2 and preventing the pipeline from falling off due to vibration.

[0022] A protective outer ring 3 is slidably mounted on the tube sheet body 1, a reinforcing ring 9 is connected to the inner wall of the tube sheet body 1, a reinforcing rib plate 10 is connected to the inner wall of the tube sheet body 1, there are two reinforcing rib plates 10 and they are cross-connected together, the reinforcing rib plates 10 and the reinforcing ring 9 are welded to each other, and the reinforcing ring 9 and the reinforcing rib plates 10 connected together by welding divide the inner wall of the tube sheet body 1 into multiple areas, thereby strengthening the structural strength of the tube sheet body 1 and preventing the tube sheet body 1 from being greatly deformed due to impact force.

[0023] A clamping block 4 is connected to the protective outer ring 3, and the protective outer ring 3 is connected to a fixing frame 5 through the clamping block 4. A buffer mechanism 6 is connected inside the protective outer ring 3, and the buffer mechanism 6 includes a hollow rod 601, and a moving rod 602 is slidably connected inside the hollow rod 601. One end of the moving rod 602 extending into the hollow rod 601 and the inside of the hollow rod 601 are both connected with a buffer ball 603. By pushing the moving rod 602 to move inside the hollow rod 601, the buffer ball 603 on the moving rod 602 and the buffer ball 603 in the hollow rod 601 are squeezed against each other, thereby buffering the impact force generated by the vibration.

[0024] A damper 7 is connected inside the protective outer ring 3, and one end of the buffer mechanism 6 and the damper 7 are connected to the inner wall of the tube sheet body 1. A buffer ring 11 is connected at the contact point between the outer wall of the tube sheet body 1 and the inner wall of the protective outer ring 3. A total of six dampers 7 are distributed inside the protective outer ring 3 in a manner symmetrical about the axis of the protective outer ring 3. The buffer mechanism 6 is arranged between two dampers 7. When the tube sheet body 1 moves toward the side of the protective outer ring 3, the buffer ring 11 can prevent the outer wall of the tube sheet body 1 from scratching the protective outer ring 3, thereby protecting the tube sheet body 1, and the multiple dampers 7 and buffer mechanisms 6 can improve the buffering effect of vibration.

[0025] A shock-absorbing spring 8 is sleeved on the damper 7, one end of the shock-absorbing spring 8 is connected to the inner wall of the tube plate body 1, and the other end of the shock-absorbing spring 8 is connected to the inner wall of the protective outer ring 3. A card slot 14 is provided on the fixing frame 5, and a second threaded hole 15 is provided on the fixing frame 5. There are four blocks 4 in total and they are symmetrical about the axis center of the protective outer ring 3. The blocks 4 and the card slots 14 are embedded with each other, and first threaded holes 12 are provided on the blocks 4 and in the card slots 14. Bolts 13 are connected to the inner threads of the first threaded holes 12. Through the embedding of the blocks 4 and the card slots 14, the staff can quickly complete the positioning and installation of the protective outer ring 3 to prevent the protective outer ring 3 from accidentally moving when the staff turns the bolts 13, resulting in unstable fixation of the bolts 13.

[0026] The working principle of the utility model is:

[0027] By embedding the block 4 into the slot 14, the protective outer ring 3 can be fixed on the fixing frame 5, and then the bolt 13 is screwed into the first threaded hole 12 to strengthen the stability of the connection. When the flow rate of the liquid in the pipeline is too fast, the tube sheet body 1 will slide to the side of the protective outer ring 3, so that the tube sheet body 1 can squeeze the damper 7 and the shock absorbing spring 8, so as to use the compression shock absorbing spring 8 to buffer the impact force, and the damper 7 can absorb and reduce the vibration. At the same time, the tube sheet body 1 will push the moving rod 602 to move into the hollow rod 601, so that the buffer ball 603 at one end of the moving rod 602 and the buffer ball 603 inside the hollow rod 601 are squeezed against each other, so as to buffer the impact force and reduce the impact force on the tube sheet body 1. The inside of the tube sheet body 1 is divided into multiple force-bearing areas by the reinforcing ring 9 and the reinforcing rib plate 10, so that the tube sheet body 1 is not easily deformed by vibration impact.
