Description

Technical Field

[0001] This utility model belongs to the field of sealing technology, and in particular relates to an elastomer installation device for a non-disc-shaped end face sealing element. Background Technology

[0002] A spring seal (also known as a spring-energized seal or variseal) is a high-performance U-shaped Teflon seal with an internal special spring. The appropriate spring force, combined with system fluid pressure, pushes the sealing lip (face) forward, gently pressing it against the metal surface to create an excellent seal. The spring's actuation effect overcomes slight misalignment of the metal mating surfaces and wear of the sealing lip, thus maintaining the desired sealing performance over time.

[0003] Traditional installation methods present several challenges when installing V-shaped spring components on seals. On one hand, it is difficult to accurately embed the V-shaped spring component into the groove of the seal and securely install it, which can easily lead to insecure installation. On the other hand, it is difficult to ensure the tightness between the inner arc surface of the V-shaped spring component and the seal after installation, which affects the sealing effect. Utility Model Content

[0004] The purpose of this utility model is to provide an elastomer installation device for non-disc-shaped end face plug seals, which solves the many problems that exist in the traditional installation method when installing V-shaped spring parts on seals. On the one hand, it is difficult to accurately embed the V-shaped spring parts into the groove of the seal and install them securely, which easily leads to problems with insecure installation.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a non-disc-type end face plug seal elastomer installation device, including a frame, on which a clamping mechanism and an installation mechanism are provided;

[0007] The clamping mechanism includes a motor fixedly connected to the left side of the frame. The output end of the motor is fixedly connected to a bidirectional threaded rod. The bidirectional threaded rod rotatably passes through the frame. The outer wall of the bidirectional threaded rod is threaded with two moving blocks. The two moving blocks are slidably connected to the inner bottom wall of the frame. A sealing element is provided between the two moving blocks. The inner wall of the sealing element has a slot. The inner wall of the slot is provided with a V-shaped spring.

[0008] The top of the seal is provided with an installation mechanism, which includes a second motor fixedly connected to the right side of the frame, and the output end of the second motor is fixedly connected to a second bidirectional threaded rod.

[0009] Furthermore, two slide rods are fixedly connected to the inner wall of the frame, and two moving blocks are threadedly connected to the outer wall of the bidirectional threaded rod 2. Both slide rods slide through the two moving blocks 2.

[0010] Furthermore, each of the two movable blocks 2 has two hinge blocks 1 rotatably connected to its opposite side, and each of the four hinge blocks 1 has a telescopic rod 1 fixedly connected to its opposite side.

[0011] Furthermore, each of the four telescopic rods is fixedly connected to a hinge block 2 at the end away from the hinge block 1, and each of the four hinge blocks 2 is rotatably connected to a positioning rod on the side away from the telescopic rod 1. Each of the four positioning rods is rotatably connected to a roller at the bottom end, and the inner wall of the V-shaped spring is in contact with the outer wall of the four rollers.

[0012] Furthermore, each of the four positioning rods has a hinge block three rotatably connected to its top surface, and two telescopic rods two are fixedly connected between two hinge blocks three on the same side.

[0013] Furthermore, each of the four positioning rods has a spring wound around its outer wall. One end of the spring is fixedly connected to the hinge block, and the other end of the spring is fixedly connected to the hinge block.

[0014] Furthermore, the outer walls of the four telescopic rods are all wound with springs, and the two ends of the springs are respectively fixedly connected to the two hinge blocks on the same side.

[0015] This utility model has the following beneficial effects:

[0016] 1. By setting up a clamping mechanism, when the drive motor drives the bidirectional threaded rod to rotate, it will drive the two moving blocks to move closer to each other, so that the two moving blocks can contact the outer wall of the seal and fix the seal. The seal can be fixed at the top center of the frame, so that the V-shaped spring inside the seal can be accurately positioned during installation, thus making the seal more stable after positioning.

[0017] 2. With the installation mechanism, the motor can drive the bidirectional threaded rod to rotate, causing the two moving blocks to move away from each other. The bottom rollers of the four positioning rods can drive the V-shaped spring to spread outward, so that the V-shaped spring can be embedded in the groove of the seal to install and fix the V-shaped spring. As the two moving blocks continue to move away from each other, multiple springs are continuously compressed, causing multiple rollers to roll on the inner wall of the V-shaped spring, thereby pressing and fixing the inner arc surface of the V-shaped spring to ensure tightness after installation.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figure 1-6As shown, this utility model is an elastomer installation device for a non-disc-type end face plug sealant, including a frame 1, on which a clamping mechanism 2 and an installation mechanism 3 are provided;

[0030] The clamping mechanism 2 includes a motor 21 fixedly connected to the left side of the frame 1. The output end of the motor 21 is fixedly connected to a bidirectional threaded rod 22. The bidirectional threaded rod 22 rotatably passes through the frame 1. The outer wall of the bidirectional threaded rod 22 is threadedly connected to two moving blocks 23. The two moving blocks 23 are slidably connected to the inner bottom wall of the frame 1. A sealing element 4 is provided between the two moving blocks 23. A groove 42 is opened on the inner wall of the sealing element 4. A V-shaped spring 41 is provided on the inner wall of the groove 42. By setting the clamping mechanism 2, the sealing element 4 can be fixed at the top center of the frame 1, so that the V-shaped spring 41 inside the sealing element 4 can be accurately positioned during installation, thereby making the sealing element 4 more stable after positioning.

[0031] A mounting mechanism 3 is provided on the top of the seal 4. The mounting mechanism 3 includes a motor 31 fixedly connected to the right side of the frame 1. A bidirectional threaded rod 32 is fixedly connected to the output end of the motor 31. Two sliding rods 33 are fixedly connected to the inner wall of the frame 1. Two moving blocks 34 are threadedly connected to the outer wall of the bidirectional threaded rod 32. The two sliding rods 33 slide through the two moving blocks 34. Two hinge blocks 35 are rotatably connected to the opposite sides of the two moving blocks 34. Telescopic rods 36 are fixedly connected to the opposite sides of the four hinge blocks 35. Hinge blocks 37 are fixedly connected to the opposite ends of the four telescopic rods 36. Positioning rods 38 are rotatably connected to the opposite sides of the four hinge blocks 37. The bottom end of each component is rotatably connected to a roller. The inner wall of the V-shaped spring component 41 contacts the outer wall of the four rollers. The top surface of each of the four positioning rods 38 is rotatably connected to a hinge block 39. Two telescopic rods 391 are fixedly connected between two hinge blocks 39 on the same side. The outer wall of each of the four positioning rods 38 is wrapped with a spring 361. One end of the spring 361 is fixedly connected to a hinge block 37, and the other end of the spring 361 is fixedly connected to a hinge block 35. The outer wall of each of the four telescopic rods 391 is wrapped with a spring 392. Both ends of the spring 392 are fixedly connected to two hinge blocks 39 on the same side. By setting up the installation mechanism 3, multiple rollers can roll on the inner wall of the V-shaped spring component 41, thereby pressing and fixing the inner arc surface of the V-shaped spring component 41 to ensure tightness after installation.

[0032] A specific application of this embodiment is as follows: by setting up a clamping mechanism 2, when the drive motor 21 drives the bidirectional threaded rod 22 to rotate, it will drive the two moving blocks 23 to move closer to each other, so that the two moving blocks 23 can contact the outer wall of the seal 4 and thus fix the seal 4. The seal 4 can be fixed at the top center of the frame 1, so that the V-shaped spring 41 inside the seal 4 can be accurately positioned during installation, thereby making the seal 4 more stable after positioning.

[0033] With the installation mechanism 3 in place, when the drive motor 31 drives the bidirectional threaded rod 32 to rotate, the two sliding rods 33 cooperate to move the two moving blocks 34 on the sliding rods 33 away from each other. At this time, the V-shaped spring 41 is sleeved on the outer wall of the four positioning rods 38. Due to the elasticity of the V-shaped spring 41, and the contraction of the four telescopic rods 391 and 36, the four springs 361 and 392 are compressed. Under the outward diffusion force of the multiple springs, the V-shaped spring 41 can be stretched and positioned by the four positioning rods 38 on the seal. At the internal center of 4, the motor 31 drives the bidirectional threaded rod 32 to rotate, causing the two moving blocks 34 to move away from each other. The bottom rollers of the four positioning rods 38 can drive the V-shaped spring 41 to spread outward, so that the V-shaped spring 41 can be embedded in the slot 42 of the seal 4 to install and fix the V-shaped spring 41. As the two moving blocks 34 continue to move away from each other, multiple springs are continuously compressed, so that multiple rollers can roll on the inner wall of the V-shaped spring 41, thereby pressing and fixing the inner arc surface of the V-shaped spring 41 to ensure the tightness after installation.
