Description

A connection device for automatic drain valve of air separation circulating water in a smelter Technical Field

[0001] This utility model relates to the field of automatic drain valve installation technology, specifically to a connection device for an automatic drain valve of air separation circulating water in a smelter. Background Technology

[0002] The automatic drain valve for air separation circulating water in a smelter is a valve specifically designed for the circulating water system of an air separation unit. Its core function is to automatically drain condensate or other harmful liquids accumulated in pipes or equipment. The valve achieves automatic opening and closing of the drain outlet through mechanical or electronic control without manual intervention, thereby ensuring the stable operation of the air separation system.

[0003] In existing technologies, when installing automatic drain valves, different connection methods are generally used depending on the connected pipes and the pressure they bear during use. These methods include flange connections, bolt connections, welding, and clamp connections. When connecting the automatic drain valve to the inlet and outlet pipes using flange connections, the flanges need to be aligned at the same height before being secured with bolts. However, when connecting the pipes and the automatic drain valve using flange connections, the two flanges need to be aligned at the same height. During this alignment process, errors in height or lateral distance can easily occur. This can lead to misalignment of the connecting holes on the flanges when bolting them together, requiring frequent adjustments to the flange positions and increasing the inconvenience of installing the automatic drain valve. Summary of the Invention

[0004] The main purpose of this utility model is to provide a connection device for an automatic drain valve of air separation circulating water in a smelter, which solves the problem of misalignment of the holes on the flange during the installation of the existing automatic drain valve of air separation circulating water in a smelter, which makes installation inconvenient.

[0005] To achieve the above objectives, this utility model provides an automatic drain valve connection device for air separation circulating water in a smelter, comprising:

[0006] The connecting assembly includes a connecting plate disposed on the drain valve and a rotating disk rotatably connected to the connecting plate; the connecting plate is provided with a limiting member that engages with the rotating disk under external force to restrict the rotational disk's degree of freedom in the circumferential direction.

[0007] The transmission assembly includes multiple sets of transmission components rotatably connected to the rotating disk and multiple sets of pushing components slidably disposed on the connecting plate; the pushing components are rotatably connected to the transmission components; the rotating disk rotates circumferentially along the axis of the drain valve under the action of external force, thereby driving the transmission components to swing, so that the pushing components move toward or away from the axial direction of the drain valve;

[0008] The positioning component includes positioning elements disposed on the pusher, and a positioning space is formed between multiple sets of positioning elements; the positioning elements move toward or away from the axis of the drain valve under the drive of the pusher, thereby reducing or expanding the internal size of the positioning space.

[0009] As a further improvement of this utility model, the connecting plate is provided with multiple sets of sliding grooves facing the center of the connecting plate; a positioning rod is provided in the sliding groove.

[0010] As a further improvement of this utility model, the transmission component includes a connecting rod rotatably connected to the rotating disk, a rotating block disposed on the connecting rod, and a mounting rod disposed on the rotating block; the connecting rod and the mounting rod are arranged parallel to each other in opposite planes; the pushing component includes a sliding block slidably disposed in a sliding groove; the sliding block is rotatably connected to the mounting rod, and the sliding block is slidably connected to the positioning rod.

[0011] As a further improvement of this utility model, the positioning component includes a mounting block that is perpendicularly connected to the sliding block and an alignment block disposed on the mounting block; a reinforcing block is provided between the mounting block and the sliding block.

[0012] As a further improvement of this utility model, the limiting member includes a fixed plate fixedly connected to the connecting plate, a slide rod slidably disposed on the fixed plate, and a toothed plate disposed at the end of the slide rod; a spring is provided between the toothed plate and the fixed plate; the spring is sleeved on the slide rod; and a missing gear is provided on the rotating disk to mesh with the toothed plate.

[0013] As a further improvement of this utility model, a screw sleeve is rotatably provided on the fixing plate; the screw sleeve is threadedly connected to the slide rod.

[0014] The beneficial effects of this utility model are reflected in:

[0015] By setting up a connecting plate and a rotating disk to connect with the drain valve, the rotating disk drives the transmission component to swing, causing the pushing component to move towards the axis of the drain valve. This causes the positioning component to move towards the axis of the drain valve to clamp the drain valve and the external flange, aligning the flange on the drain valve with the connecting hole on the external flange. This facilitates the connection of the connecting bolts through the connecting hole. The limiting component can fix the position of the positioning component, preventing displacement of the positioning component during the installation of the drain valve and thus avoiding displacement of the drain valve, which would affect the installation.

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the described embodiments are merely some, not all, of the embodiments of this utility model. Unless otherwise specified, the embodiments and features described in this application can be combined with each other. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0027] In one embodiment, referring to Figure 1, the automatic drain valve connection device for air separation circulating water in a smelter according to the present invention includes a connection component, a transmission component, and a positioning component.

[0028] The connecting assembly includes a connecting plate 2 mounted on the drain valve 1 and a rotating disk 3 rotatably connected to the connecting plate 2. The connecting plate 2 is provided with a limiting member 4, which engages with the rotating disk 3 under external force to restrict the circumferential freedom of the rotating disk 3. The transmission assembly includes multiple sets of transmission members 5 rotatably connected to the rotating disk 3 and multiple sets of pushing members 6 slidably mounted on the connecting plate 2. The pushing members 6 are rotatably connected to the transmission members 5. Under external force, the rotating disk 3 rotates circumferentially along the axis of the drain valve 1, thereby driving the transmission members 5 to swing, so that the pushing members 6 move toward or away from the axial direction of the drain valve 1. The positioning assembly includes a positioning member 7 mounted on the pushing member 6. The multiple sets of positioning members 7 form a positioning space 8. The positioning member 7 moves toward or away from the axis of the drain valve 1 under the action of the pushing member 6, thereby reducing or expanding the internal size of the positioning space 8.

[0029] Furthermore, referring to Figures 1, 2, 3, and 5, the connecting plate 2 is provided with multiple sets of sliding grooves 9 facing the center of the connecting plate 2, and positioning rods 10 are provided in the sliding grooves 9.

[0030] Preferably, the connecting plate 2 has a mounting hole 12 at its center, and the connecting plate 2 is sleeved on the drain valve 1 through the mounting hole 12 and fixedly connected to the drain valve 1.

[0031] Preferably, the rotating disk 3 has a rotating hole 13 at its center. The inner diameter of the rotating hole 13 is larger than the outer diameter of the drain valve 1. The rotating disk 3 is mounted on the connecting sleeve 23 via the transmission component 5 and the pushing component 6.

[0032] Preferably, the positioning rod 10 is located at the bottom center of the slide groove 9, and the positioning rod 10 is arranged parallel to the axis of the slide groove 9.

[0033] Furthermore, referring to Figures 2, 3, 5, and 6, the transmission component 5 includes a connecting rod 501 rotatably connected to the rotating disk 3, a rotating block 502 disposed on the connecting rod 501, and a mounting rod 503 disposed on the rotating block 502. The connecting rod 501 and the mounting rod 503 are arranged parallel to each other in opposite planes. The pushing component 6 includes a sliding block 601 slidably disposed in the slide groove 9. The sliding block 601 is rotatably connected to the mounting rod 503 and slidably connected to the positioning rod 10.

[0034] Preferably, the rotating disk 3 has a square structure, and four sets of first connecting holes 14 are equally arranged on the rotating disk 3, and the connecting rod 501 rotates and is located in the first connecting holes 14.

[0035] Preferably, the rotating block 502 has an "L" shaped structure, the sliding block 601 has a second connecting hole 15 on the outer wall of the sliding groove 9 perpendicular to it, the sliding block 601 has a sliding hole 16 at the bottom of the sliding groove 9 parallel to it, the mounting rod 503 is rotatably located in the second connecting hole 15, the sliding hole 16 is slidably connected to the positioning rod 10; the connecting rod 501 is connected to the long side end of the rotating block 502, and the mounting rod 503 is connected to the short side end of the rotating block 502.

[0036] Preferably, the rotating disk 3 is provided with a rotating handle 17; the end of the positioning rod 10 that passes through the sliding block 601 is provided with a limiting block 11, which can limit the sliding block 601 and prevent the sliding block 601 from moving out of the slide groove 9.

[0037] In the above configuration, rotating the handle 17 drives the rotating disk 3 to rotate. The rotation of the rotating disk 3 causes the connecting rod 501 and the rotating block 502 to swing. The rotation and swinging cause the mounting rod 503 to move. Since the mounting rod 503 is connected to the sliding block 601, and the sliding block 601 is slidably mounted on the slide groove 9 and the positioning rod 10, the sliding block 601 can only move along the axial direction of the slide groove 9. After multiple sets of sliding blocks 601 move toward the axis of the drain valve 1, they drive multiple sets of positioning parts 7 to move toward the axis of the drain valve 1, thereby reducing the size of the positioning space 8. After multiple sets of sliding blocks 601 move away from the axis of drain valve 1, they drive multiple sets of positioning parts 7 to move away from the axis of drain valve 1, thereby expanding the size of the positioning space 8. The movement of sliding blocks 601 toward or away from the axis of drain valve 1 can be achieved by adjusting the rotation direction of the rotating handle 17. For example, rotating the rotating handle 17 clockwise will cause the rotating disk 3 to rotate clockwise, causing the rotating block 502 to swing, which will pull the sliding block 601 toward the axis of drain valve 1. Conversely, rotating it counterclockwise will push the sliding block 601 away from the axis of drain valve 1.

[0038] It should be noted that during the movement of the sliding block 601 along the slide groove 9, although there will be friction between the sliding block 601 and the slide groove 9 and the positioning rod 10, lubricating oil can be added to the sliding block 601, the slide groove 9 and the positioning rod 10 to reduce the friction. In addition, the connecting rod 501 and the mounting rod 503 on the rotating block 502 are rotatably connected to the rotating disk 3 and the sliding block 601 respectively. During the rotation of the rotating disk 3, the rotating block 502 swings accordingly, which can drive the sliding block 601 to move in the slide groove 9.

[0039] Furthermore, referring to Figures 2, 3, and 4, the positioning element 7 includes a mounting block 701 that is vertically connected to the sliding block 601, an alignment block 702 disposed on the mounting block 701, and a reinforcing block 703 disposed between the mounting block 701 and the sliding block 601.

[0040] Preferably, the mounting block 701 has an "L" shaped structure, the long side end of the mounting block 701 is fixedly connected to the sliding block 601, the short side end of the mounting block 701 is set parallel to the sliding block 601, and the end face of the alignment block 702 facing the axis of the drain valve 1 is arc-shaped.

[0041] In the above configuration, when the sliding block 601 moves along the slide groove 9 toward the axis of the drain valve 1, the mounting block 701 and the alignment block 702 move toward the axis of the drain valve 1, thereby reducing the positioning space 8. After the alignment block 702 moves, it can abut against the first flange 18 on the drain valve 1 and at the same time abut against the external second flange 19, clamping and aligning the first flange 18 and the second flange 19, so that the bolt connection holes on the first flange 18 and the second flange 19 are aligned.

[0042] Furthermore, referring to Figures 1, 2, and 7, the limiting member 4 includes a fixed plate 401 fixedly connected to the connecting plate 2, a slide rod 402 slidably disposed on the fixed plate 401, and a toothed plate 403 disposed at the end of the slide rod 402. A spring 404 is provided between the toothed plate 403 and the fixed plate 401. The spring 404 is sleeved on the slide rod 402. A missing gear 20 is provided on the rotating disk 3 to mesh with the toothed plate 403.

[0043] Preferably, the fixing plate 401 is provided with a sliding hole 405, and the sliding rod 402 is installed in the sliding hole 405.

[0044] Preferably, a connecting block 21 is provided between the missing gear 20 and the rotating disk 3, and the rotating handle 17 is connected to the missing gear 20.

[0045] In the above setup, before rotating the handle, the slide bar 402 needs to be pulled upwards to compress the spring 404 and move the toothed plate 403 upwards to separate it from the missing gear 20. Only then can the missing gear 20 be rotated by rotating the handle. After the missing gear 20 rotates, it drives the rotating disk 3 to rotate together with the connecting block 21, thereby driving the slide block 601 to move in the slide groove 9. This causes the alignment block 702 to move toward the axis of the drain valve 1 to clamp the first flange 18 and the second flange 19. After clamping and aligning the first flange 18 and the second flange 19, the slide bar 402 is released. Under the action of the spring 404, the toothed plate 403 is pushed to mesh with the missing gear 20, thereby fixing the position of the missing gear 20 and the rotating disk 3, and then fixing the position of the alignment block 702. This allows the alignment block 702 to continuously clamp the first flange 18 and the second flange 19, making it convenient to use bolts to connect the first flange 18 and the second flange 19, thus completing the installation of the drain valve 1.

[0046] Furthermore, referring to Figures 1, 7, and 8, a screw sleeve 22 is rotatably provided on the fixing plate 401, and the screw sleeve 22 is threadedly connected to the slide rod 402.

[0047] Preferably, the fixing plate 401 is provided with a connecting sleeve 23, the connecting sleeve 23 is provided with a connecting groove 24, and the screw sleeve 22 is provided with a connecting protrusion 25 that is rotatably located in the connecting groove 24.

[0048] In the above configuration, the sliding rod 402 can be moved up or down by rotating the threaded sleeve 22 under the action of the thread. After the sliding rod 402 moves down and the toothed plate 403 meshes with the missing gear 20, the threaded connection between the sliding rod 402 and the threaded sleeve 22 can lock the position of the sliding rod 402. This prevents the missing gear 20 from pushing the rack when it rotates in the opposite direction due to the weight of the flange, causing the sliding rod 402 to move together. This ensures that the missing gear 20 limits the toothed plate 403 and the rotating disk 3.

[0049] Referring to Figure 1, a support frame is also provided to facilitate support for the drain valve 1. The support frame includes a base plate 26 and a frame body 27 located on the base plate 26. The frame body 27 is provided with a slot for connecting to the drain valve 1. The base plate 26 is provided with a threaded hole 28 that can be connected to the ground or other equipment by bolts, thereby providing a support foundation for the drain valve 1.

[0050] In this embodiment, the drain valve 1 is supported by a support frame. The outer second flange 19 is positioned opposite and in contact with the first flange 18. Rotating the threaded sleeve 22 causes the slide rod 402 to move upward, separating the toothed plate 403 from the missing gear 20, thus releasing the restriction on the rotating disk 3. Rotating the rotating handle 17 drives the missing gear 20 and the rotating disk 3 to rotate. The rotating disk 3 drives the rotating block 502 to swing, causing the sliding block 601 to move toward the axis of the drain valve 1. The alignment block 702 moves accordingly and clamps the outside of the first flange 18 and the second flange 19, aligning the connecting holes on the first flange 18 and the second flange 19. This facilitates the connection of the connecting screw through the connecting holes on the first flange 18 and the second flange 19, thereby completing the installation of the drain valve 1.

[0051] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
