Description

Technical Field

[0001] The invention belongs to the technical field of connection and reinforcement of polytetrafluoroethylene pipes, and in particular relates to a connection and reinforcement mechanism for steel-lined polytetrafluoroethylene pipes. Background Art

[0002] Steel-lined PTFE pipe is made of ordinary carbon steel pipe as the base, lined with thermoplastic polytetrafluoroethylene plastic with excellent chemical stability, and processed by a specific process. It has both the mechanical properties of steel pipe and the characteristics of high corrosion resistance, slow scaling, and low growth of microorganisms of polytetrafluoroethylene plastic. It is an ideal pipeline for transporting strong acids, strong alkalis, industrial salts and highly corrosive gases. Steel-lined PTFE pipe has good corrosion resistance. Steel-PTFE composite pipe can resist almost all chemical media, including concentrated nitric acid and aqua regia, except molten metal lithium, potassium, sodium, chlorine trifluoride, high temperature oxygen trifluoride, and high-flow liquid fluorine. It can work at 230℃-250℃ for a long time.

[0003] In the prior art, two sections of steel-lined PTFE pipes are mostly connected by flange connection, which is installed into multiple groups of mounting holes of two groups of flanges with bolts and nuts. The flanges are simply fixed directly by bolts and nuts to achieve the fixation of the two sections of steel-lined PTFE pipes. After long-term use, the connection between the two sections of steel-lined PTFE pipes will become loose, thereby affecting the normal use of the steel-lined PTFE pipes.

[0004] To this end, we provide a connection reinforcement mechanism for steel-lined polytetrafluoroethylene pipes to solve the above-mentioned problems. Summary of the invention

[0016] The present invention has the following beneficial effects:

[0017] 1. The present invention drives the first abutment plate to move leftward by screwing the bolt, thereby driving the insertion rod and the rotating rod to move leftward. At the same time, the left side of the second abutment plate is blocked by hand, so that the hand has a blocking effect on the leftward movement of the second baffle plate.

[0018] 2. The present invention allows the bolt to move toward the inside of the first protective member during the process of screwing the bolt, so that the bolt thread is connected to the screw hole in the hexagonal sleeve. At the same time, under the limiting action of the slide plate, the hexagonal sleeve is moved to the right along the bolt, so that the hexagonal sleeve is sleeved on the outer wall of the first nut, and the first nut is limited synchronously to prevent the first nut from rotating with the bolt during the process of screwing the bolt, thereby causing the bolt and the first nut to be unable to fix the first flange and the second flange. After the first flange and the second flange are fixed by the bolt and the first nut, the hexagonal sleeve just fits against the left side wall of the first flange, and at the same time, with the use of the cylindrical tube, the threaded connection between the first nut and the bolt is covered and protected to prevent external rainwater from corroding the threaded connection between the first nut and the bolt, thereby affecting subsequent disassembly.

[0019] 3. After the first abutment plate and the second abutment plate complete the clamping of the second flange and the first flange, the present invention presses the arc rod to make the arc rod abut against the contact plate, thereby driving the contact plate and the protective tube to move toward the second flange, so that the protective tube cover is arranged on the outside of the bolt, thereby protecting the nut of the bolt and preventing rain from corroding the nut, thereby affecting the subsequent disassembly of the first pipe and the second pipe.

[0020] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

The first reinforcement component 6 also includes a second nut 604 that is threadedly connected to the side surface of the plug rod 602, and a thread 605 that matches the second nut 604 is provided on the side surface near the other end of the plug rod 602. A support member 7 is rotatably inserted on the outer wall of the plug rod 602; the support member 7 includes a rotating rod 701 that is rotatably inserted on the plug rod 602, and both ends of the rotating rod 701 are fixedly connected to the first rotating plate 702. A rotating shaft 703 is fixedly connected to one side of 702, and a second rotating plate 704 is fixedly connected to the end of the rotating shaft 703. A through sliding groove 705 is provided on one side of the first rotating plate 702, and a gear 706 is fixedly connected to the peripheral side of the rotating rod 701; a second reinforcing assembly 8 is slidably matched with the peripheral side of the second pipe 2, and the second reinforcing assembly 8 includes a second annular plate 801 slidably sleeved on the peripheral side of the second pipe 2, and a connecting plate 802 is symmetrically fixedly connected to one side of the second annular plate 801, and a second abutment plate 803 slidably matched on the peripheral side of the corresponding insertion rod 602 is fixedly connected to one side of the connecting plate 802 , the two opposite side surfaces of the connecting plate 802 are fixedly connected with sleeves 804, and a first slide bar 805 connected by a first spring is slidably inserted inside the sleeve 804, and the first slide bar 805 slidably cooperates with the corresponding first rotating plate 702, and a locking plate 806 is slidably connected to the connecting plate 802, and the two opposite side surfaces of the locking plate 806 are fixedly connected with sleeves 807, and a second slide bar 808 connected by a second spring is slidably inserted inside the sleeve 807, and the second slide bar 808 rotates in cooperation with the corresponding second rotating plate 704, and a tooth plate 813 meshing with the gear 706 is fixedly connected to one side of the second abutment plate 803.

[0039] The operation process of this embodiment is as follows: first, the second annular plate 801 in the second reinforcement component 8 is sleeved on the outer wall of the second pipe 2, and then the insertion rod 602 in the first reinforcement component 6 is correspondingly inserted on the second abutment plate 803, and at the same time, the angle of the first abutment plate 603 on the insertion rod 602 is adjusted so that the first abutment plate 603 is aligned with the mounting hole on the second flange 4 (at this time, the first abutment plate 603 is located on the right side of the second flange 4, and the second abutment plate 803 is located on the left side of the first flange 3, as shown in FIG. Figure 2 As shown), the bolts 501 are then inserted into the mounting holes between the first flange 3 and the second flange 4, and then the first nut 502 is installed on the outer wall of one end of the bolt 501 close to the first flange 3, and then the first annular plate 601 is sleeved and installed on the outer wall of the first pipe 1, and at the same time, the first annular plate 601 is slidably fitted on the insertion rod 602 and on the insertion rod 602, and then the second nut 604 is screwed on the insertion rod 602, so that the second nut 604 limits the first annular plate 601.

[0040] Then, the first slide bar 805 is pressed in the direction of the sleeve 804 (the first spring in the sleeve 804 is in a compressed state at this time), and then the angle of the first rotating plate 702 is adjusted to the position where it cooperates with the first slide bar 805. Then, the first slide bar 805 is released, and under the elastic force of the first spring, the first slide bar 805 is moved in the direction close to the corresponding first rotating plate 702, so that the first slide bar 805 and the slide groove 705 are slidably matched, and the sliding matching installation of the first slide bar 805 and the first rotating plate 702 is completed. Then, the second slide bar 808 is pressed to make the second slide bar 808 move toward the inside of the sleeve 807 (the second spring in the sleeve 807 is in a compressed state at this time), and then the angle of the second rotating plate 704 is adjusted to the position where it cooperates with the second slide bar 808, and the second slide bar 808 is released. Under the action of the second spring, the second slide bar 808 is driven to move in the direction close to the second rotating plate 704, thereby completing the rotation matching of the first slide bar 805 and the first rotating plate 702.

[0041] By tightening the bolt 501, the nut of the bolt 501 drives the first abutment plate 603 to move leftward, thereby driving the insertion rod 602 and the rotating rod 701 to move leftward. At the same time, the left side of the second abutment plate 803 is blocked by hand, so that the hand has a blocking effect on the leftward movement of the second baffle plate 803. During the movement of the rotating rod 701 to the left, the gear 706 is meshed with the toothed plate 813, so that the gear 706 rotates clockwise, and then the gear 706 drives the first rotating plate 702 to rotate clockwise with the rotating rod 701 as the axis (such as Figure 4 As shown), the first rotating plate 702 drives the connecting plate 802 to move rightward, and the connecting plate 802 further drives the second abutting plate 803 to move rightward, so that the second abutting plate 803 abuts against the left side wall of the first flange 3, and the first abutting plate 603 abuts against the right side wall of the second flange 4;

[0042] By the process of the first rotating plate 702 rotating clockwise and the insertion rod 602 moving to the left, the first rotating plate 702 synchronously drives the second rotating plate 704 to rotate and move to the left, thereby driving the locking plate 806 to move to the left and downward through the second rotating plate 704. When the first abutment plate 603 just abuts against the right side surface of the second flange 4, the locking plate 806 just abuts against the right side wall of the first abutment plate 603, thereby completing the position locking of the first abutment plate 603, and completing the fixation between the first pipeline 1 and the second pipeline 2 by the process of fastening the first flange 3 and the second flange 4 through the fastening assembly 5. The first abutment plate 603 and the second abutment plate 803 are synchronously driven to move toward the outer walls of the corresponding second flange 4 and the first flange 3, thereby completing the further fixation between the first flange 3 and the second flange 4, and then realizing the further reinforcement of the connection between the first pipeline 1 and the second pipeline 2, thereby improving the firmness of the connection between the first pipeline 1 and the second pipeline 2.

[0043] For example 2, please refer to Figure 1-12 The second embodiment is improved on the basis of the first embodiment as follows: a first protective member 9 for protecting the first nut 502 is symmetrically fixedly matched on one side of the first circular plate 601, and the first protective member 9 includes a cross bar 901 fixedly connected to one side of the first circular plate 601, and a cylindrical tube 902 is fixedly connected to one end of the cross bar 901, and a slide plate 903 is symmetrically slidably connected to the inner circumferential side of the cylindrical tube 902, and a hexagonal sleeve 904 is fixedly connected between the two slide plates 903, and a screw hole that is threadedly matched with the bolt 501 is opened inside the hexagonal sleeve 904.

[0044] The operation process of this embodiment is as follows: during the process of screwing the bolt 501, the bolt 501 is moved toward the inside of the first protective member 9, so that the bolt 501 is threadedly connected to the screw hole in the hexagonal sleeve 904; at the same time, under the limiting action of the slide plate 903, the hexagonal sleeve 904 is moved to the right along the bolt 501, so that the hexagonal sleeve 904 is sleeved on the outer wall of the first nut 502, and the first nut 502 is simultaneously limited to prevent the first nut 502 from moving along with the bolt 501 during the process of screwing the bolt 501. The first flange 3 and the second flange 4 are rotated together, so that the bolt 501 and the first nut 502 cannot fix the first flange 3 and the second flange 4. After the first flange 3 and the second flange 4 are fixed by the bolt 501 and the first nut 502, the hexagonal sleeve 904 just fits on the left side wall of the first flange 3, and the cylindrical tube 902 is used to cover and protect the threaded connection between the first nut 502 and the bolt 501, so as to prevent the external rainwater from corroding the threaded connection between the first nut 502 and the bolt 501, thereby affecting the subsequent disassembly;

[0045] In addition, when the bolt 501 moves to the left, the left end of the bolt 501 contacts the inside of the cylindrical tube 902, driving the cylindrical tube 902 and the cross bar 901 to move to the left, so that the cross bar 901 drives the first circular ring plate 601 to move to the left, so that the first circular ring plate 601 is tightly attached to the second nut 604, thereby ensuring the stability of the movable connection of the first circular ring plate 601.

[0046] For example 3, please refer to Figure 1-12 The third embodiment is improved on the basis of the first embodiment as follows: a locking piece 10 is fixedly fitted on one side of the first abutment plate 603, and the locking piece 10 includes an L-shaped plate 1001 fixedly connected to one side of the first abutment plate 603, a abutment rod 1002 is slidably inserted on the L-shaped plate 1001, and a baffle 1003 is fixedly connected to the end of the abutment rod 1002 away from the first abutment plate 603, and a return spring 1004 is fixedly connected between the L-shaped plate 1001 and the baffle 1003 and is sleeved on the side surface of the abutment rod 1002.

[0047] The operation process of this embodiment is as follows: during the process of the locking plate 806 moving toward the first abutment plate 603, the locking plate 806 abuts against the abutment rod 1002, driving the abutment rod 1002 to move away from the locking plate 806 (at this time, the reset spring 1004 is in a stretched state), and when the locking hole 812 on the locking plate 806 moves to a position concentric with the abutment rod 1002, under the elastic force of the reset spring 1004, the abutment rod 1002 is driven to move toward the inside of the locking hole 812, thereby completing the locking of the locking plate 806, and further ensuring the stability of the first abutment plate 603 and the second abutment plate 803 when clamping the second flange 4 and the first flange 3.

[0048] Example 4, please refer to Figure 1-12 , this embodiment four makes the following improvements on the basis of embodiment one: a second protective member 11 is symmetrically slidably fitted on one side of the second circular ring plate 801, and the second protective member 11 includes a moving rod 1101 slidably inserted on the side of the second circular ring plate 801, one end of the moving rod 1101 is fixedly connected to a protective tube 1102, and the other end of the moving rod 1101 is fixedly connected to a contact plate 1103, and the second reinforcement component 8 also includes an arc rod 809 hinged on one side of the second circular ring plate 801 and connected through a torque spring and abutting against the corresponding contact plate 1103, an extension rod 810 is symmetrically fixedly connected to one side of the second circular ring plate 801, and a C-shaped lock buckle 811 adapted to the corresponding arc rod 809 is rotatably fitted on the circumferential side of the extension rod 810.

[0049] The operation process of this embodiment is: after the second flange 4 and the first flange 3 are clamped by the first abutment plate 603 and the second abutment plate 803, the arc rod 809 is pressed to make the arc rod 809 abut against the contact plate 1103, thereby driving the contact plate 1103 and the protective tube 1102 to move toward the second flange 4, so that the protective tube 1002 is covered on the outside of the bolt 501, thereby protecting the nut of the bolt 501 and preventing the nut from being corroded by rainwater, thereby affecting the subsequent disassembly of the first pipe 1 and the second pipe 2. At this time, the arc rod 809 is inside the C-shaped lock buckle 811, and then the C-shaped lock buckle 811 is rotated to make the notch of the C-shaped lock buckle 811 misaligned with the arc rod 809, thereby completing the locking of the arc rod 809.
