Description

Technical Field

[0001] The utility model relates to the technical field of valve trays, in particular to a novel combined guiding valve tray. Background Art

[0002] The guiding valve tray is an internal tower equipment widely used in industries such as chemical engineering and oil refining. It combines the advantages of traditional valve trays and has been optimized and improved.

[0003] According to a valve tray disclosed in Chinese Patent No. CN 205379782 U, which includes a tower plate and floating valves. The tower plate is provided with installation holes for installing the floating valves. The floating valve includes a valve cover and valve legs provided at both ends of the valve cover and perpendicular to the valve cover. Side holes are provided on the leg plates of the valve legs, and a partition strip is lapped on the inner side wall of the side holes. The valve cover is provided with a plurality of convex caps arched upward, and a plurality of air holes extending axially and distributed in a circumferential direction are provided on the side walls of the convex caps. This valve tray can effectively disperse the gas flow and promote full contact between gas and liquid.

[0004] According to a guiding high-efficiency valve tray disclosed in Chinese Patent No. CN 217409781 U, which includes a main suspension plate. A splicing suspension plate is arranged on one side of the main suspension plate, and an auxiliary suspension plate is arranged on the other side of the main suspension plate. A plurality of through gas grooves are opened inside the main suspension plate and the auxiliary suspension plate. An upper-stage closing plate is arranged above the through gas grooves. A secondary gas groove is opened inside the upper-stage closing plate. A secondary closing plate is arranged on the upper end surface of the secondary gas groove. One end of a stable limiting rod is connected with a stable sliding block, and the outer wall of the stable sliding block is connected with a stable sliding groove. Force-bearing handles are connected to both sides of the upper end surface of the main suspension plate. This guiding high-efficiency valve tray can seal the edge of the secondary closing plate through the provided flexible plastic elastic ring, so as to achieve a good closing effect. Moreover, the flexible plastic elastic ring can replace the upper-stage closing plate to contact and wear with the secondary closing plate. When replacement is needed, only the flexible plastic elastic ring needs to be replaced.

[0005] Although the square valve tray in the prior art can effectively disperse the gas flow and promote full contact between gas and liquid, the following problems will exist in the actual use process: The existing square valve tray is generally complex to assemble and requires the use of extra tools for disassembly and assembly. Secondly, when the rising gas phase passes through the holes on the floating valve, it will have countercurrent gas-liquid contact with the liquid phase on the tower plate. During this contact process, the gas phase will pass through the liquid layer and generate a bubbling phenomenon, thus forming bubbles. The existing floating valves cannot automatically pierce the bubbles, which affects gas-liquid contact. Therefore, a novel combined guiding valve tray is needed to solve the above problems. Summary of the Utility Model

[0006] The purpose of the present utility model is to solve the drawbacks existing in the prior art, and a new type of combined guiding floating valve tray is proposed.

[0007] To achieve the above purpose, the present utility model adopts the following technical scheme: a new type of combined guiding floating valve tray, including a tray body, the top of the tray body is rectangularly arrayed with openings, both sides of the openings are provided with lifting sliding grooves, both sides of the top of the tray body close to the openings are provided with bayonets, the fronts of the lifting sliding grooves are all slidably connected with sliding blocks, the tops of the sliding blocks are threadedly connected with push rods, and the tops of the push rods are clamped with valve plates.

[0026] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the following combines specific embodiments and drawings to further elaborate the present utility model. However, the following embodiments are only the preferred embodiments of the present utility model and not all of them. Based on the embodiments in the implementation manner, other embodiments obtained by those skilled in the art without creative efforts all belong to the protection scope of the present utility model.

[0027] The following describes the specific embodiments of the present utility model with reference to the drawings. Specific Embodiment 1:

[0029] Refer to Figures 1-5, a novel combined guide valve tray, comprising a tray body 1. At the top of the tray body 1, openings 2 are arranged in a rectangular array. Lifting chutes 5 are provided on both sides inside the openings 2. On both sides of the top of the tray body 1 near the openings 2, clamping slots 4 are provided. Slide blocks 16 are slidably connected to the fronts of the lifting chutes 5. Push rods 15 are threadedly connected to the tops of the slide blocks 16. Valve plates 3 are clamped to the tops of the push rods 15.

[0030] When the gas phase rises through the openings 2, the valve plates 3 will be pushed up. During the rising process of the valve plates 3, the slide blocks 16 on both sides of the bottom will smoothly move up along the lifting chutes 5.

[0031] In the middle of the top of the valve plate 3, an opening is provided. In the middle of the top of the valve plate 3, a vertical block 6 is provided. Strut rods 9 are clamped to both ends of the vertical block 6. The shape of the strut rods 9 is arc-shaped. The bottom ends of the strut rods 9 are threadedly connected to the top of the valve plate 3. A telescopic head 7 is clamped to the bottom of the vertical block 6. The bottom end of the telescopic head 7 is movably connected to a telescopic column 8. The bottom end of the telescopic column 8 is threadedly connected to a top piece 10. Prickles 11 are arranged in a circular array at the bottom of the top piece 10. The top piece 10 and the prickles 11 are threadedly connected. The top piece 10 is flush with the opening provided in the middle of the top of the valve plate 3.

[0032] At the same time, part of the gas phase will push up the top piece 11 from the middle of the valve plate 3. After the top piece 11 is pushed up, the telescopic column 8 at the top will contract into the telescopic head 7. At the same time, the prickles 11 at the bottom of the top piece 10 will prick and burst the bubbles that may be generated during the rising process. Specific embodiment two:

[0034] Refer to Figures 1-5 , on both sides of the valve plate 3, hooks 12 are snap-connected. Spiral draw ropes 14 are connected to the sides of the hooks 12.

[0035] The bottom ends of the spiral draw ropes 14 are connected to a moving plate 19. The hooks 12, the spiral draw ropes 14 and the moving plate 19 are integrated.

[0036] A clamping block 13 is clamped inside the clamping slot 4. On one side of the top of the clamping block 13, an inlay block 18 is welded. A tension spring 17 is connected between the inlay block 18 and the moving plate 19. A pricking cone 20 is threadedly connected to the outside of the moving plate 19.

[0037] The clamping block 13 is directly clamped in the clamping slots 4 on both sides of the opening 2. When the valve plate 3 rises, the moving plate 19 can be moved towards the opening 2 through the spiral draw ropes 14 on both sides. When the moving plate 19 moves towards one side, the pricking cone 20 on the side will prick and burst the bubbles generated at the edge of the opening 2. When the valve plate 3 descends, the spiral draw ropes 14 will be loosened and not under tension. At this time, the moving plate 19 will bounce back. The bounce-back mainly relies on the tension spring 17 to pull it back, and waits for the next time the valve plate 3 rises to pull the moving plate 19 again.

[0038] The whole structure is easy to install and does not require complex tools. During assembly, first screw the push rods 15 on both sides into the sliding blocks 16 with threads. There are clamping holes on both sides at the bottom of the valve plate 3. Align the clamping holes with the tops of the push rods 15 and perform clamping. In this way, the valve plate 3 can be pushed. Then, snap the clamping blocks 13 into the clamping openings 4 and hook the hooks 12 into the rings on both sides of the valve plate 3. In this way, the assembly is completed. This new type of combined guiding floating valve tray has remarkable improvements in aspects such as structural design, bubble treatment ability, and usage efficiency, providing a more efficient and reliable solution for tray equipment in industries such as chemical engineering and petroleum.

[0039] In summary:

[0040] 1. When the gas phase rises through the opening 2, it will push up the valve plate 3. During the rising process of the valve plate 3, the sliding blocks 16 on both sides of the bottom will move smoothly upward along the lifting chute 5. At the same time, part of the gas phase will push up the top plate 11 from the middle of the valve plate 3. After the top plate 11 is pushed up, the telescopic column 8 at the top will contract into the telescopic head 7. At the same time, the thorns 11 at the bottom of the top plate 10 will prick the bubbles that may be generated during the rising process.

[0041] 2. The clamping blocks 13 are directly snapped into the clamping openings 4 on both sides of the opening 2. When the valve plate 3 rises, the moving plate 19 can be moved towards the opening 2 through the spiral pull ropes 14 on both sides. When the moving plate 19 moves towards one side, the thorns 20 on the side will prick the bubbles generated at the edge of the opening 2. When the valve plate 3 descends, the spiral pull ropes 14 will loosen and be free from tension. At this time, the moving plate 19 will bounce back. The bounce-back mainly relies on the tension spring 17 to pull it back, and the moving plate 19 will be pulled again when the valve plate 3 rises next time.

[0042] The whole structure is easy to install and does not require complex tools. During assembly, first screw the push rods 15 on both sides into the sliding blocks 16 with threads. There are clamping holes on both sides at the bottom of the valve plate 3. Align the clamping holes with the tops of the push rods 15 and perform clamping. In this way, the valve plate 3 can be pushed. Then, snap the clamping blocks 13 into the clamping openings 4 and hook the hooks 12 into the rings on both sides of the valve plate 3. In this way, the assembly is completed.

[0043] It should be noted that the structure in this utility model is mainly applied to the directional floating valve tray.
