Description

Technical Field

[0001] This utility model relates to the field of sealing valve technology, and in particular to a safe storage and transportation device for octanoyl bromide nitrile with a sealing valve structure. Background Technology

[0002] Octanoyl bromoxybenzonitrile is an organic chemical intermediate containing a bromobenzene ring and a nitrile group, widely used in pharmaceuticals, pesticides, and fine chemicals. After production, it requires centralized storage and transportation to ensure a stable supply to downstream companies. During storage and transportation, to ensure the safety and stability of the material and prevent environmental pollution, storage containers or transport tanks with sealed valves are typically used at the discharge point. The sealed valve, through a tight fit between the valve body and valve core, combined with a chemically resistant sealing ring, achieves isolation and control of octanoyl bromoxybenzonitrile.

[0003] A Chinese patent has been published: a sealing structure for a valve, patent publication number: CN222798261U. This patent "includes a socket valve, with adapter rings on both sides of the socket valve to prevent positional displacement, a drain pipe fixedly installed on the top of the socket valve to prevent leakage, a reinforcing ring for positioning is snapped into the inside of the drain pipe, a valve cover for easy disassembly is fixedly installed on the top of the drain pipe, and a press cap for reducing friction and shaking is snapped into the top of the valve cover."

[0004] While this equipment can reduce wear on rotating parts, increase sealing effectiveness and service life, and clamp and press the top position to ensure no positional shift during adjustment, its valve structure uses a single valve disc or a single sealing ring for material isolation. This type of structure relies on a single-layer sealing ring between the valve core and the valve body for sealing. However, octanoyl bromoxynil is chemically reactive, volatile, and toxic. The single-layer sealing structure facing the liquid side is prone to deterioration in sealing performance over long-term use due to sealing ring aging, chemical corrosion, or internal pressure fluctuations in the storage tank. Internal pressure fluctuations are mainly caused by the expansion and contraction of gas or liquid volumes during temperature changes in the storage environment, leading to unstable internal pressure and decreased sealing performance, posing a risk of liquid leakage. A single-layer seal cannot provide secondary protection and is insufficient to effectively prevent leakage, posing potential hazards to operator health and environmental safety. Therefore, existing technology cannot meet the high-safety storage and transportation requirements of octanoyl bromoxynil, and a sealing valve structure with dual protection is urgently needed. Utility Model Content

[0005] In view of this, the purpose of this utility model is to propose a safe storage and transportation device for octanoyl bromide nitrile with a sealed valve structure, so as to solve the problem that the sealing performance of a single-layer sealing structure is prone to decline during long-term use due to aging of the sealing ring, chemical corrosion, or changes in temperature, liquid expansion, or internal pressure fluctuations in the transport tank. The single-layer seal cannot provide secondary protection and is difficult to effectively prevent leakage.

[0006] Based on the above objectives, this utility model provides a safe storage and transportation device for octanoyl bromoxynil with a sealed valve structure, including a storage tank. A sealing cover is fixedly installed on the top of the storage tank, and a discharge pipe for discharging is connected to the bottom of the storage tank. A flange is fixedly connected to the outer wall of the end of the discharge pipe away from the storage tank. A sealing mechanism for preventing leakage of octanoyl bromoxynil during storage is provided inside the discharge pipe. The sealing mechanism includes valve cores rotatably connected between the inner walls of the discharge pipe. Valve discs are fixedly connected to the outer walls of the two valve cores. Sealing outer rings are fixedly connected to the inner wall of the discharge pipe near the outer walls of the two valve discs. Three sealing rings are fixedly connected to the outer walls of the two valve discs. When the three sealing rings and the sealing outer rings are on the same vertical line, the outer walls of the three sealing rings are tightly fitted with the inner walls of the sealing outer rings to form a multi-layer seal.

[0007] Preferably, the top of the discharge pipe is fixedly connected to a housing, the shafts of the two valve cores are inserted into the interior of the housing and fixedly connected to gears, and sealing rings are fixedly connected at the connection between the two valve cores and the discharge pipe. The bottom sides of the inner wall of the housing are slidably connected to movable plates arranged opposite to each other. The movable plates are Z-shaped, and the side of the movable plate near the gear has multiple evenly distributed tooth grooves, which mesh with each other.

[0008] Preferably, a rotating plate is rotatably connected to the middle part of the inner wall of the outer shell, and two first arc-shaped grooves are opened on the top of the rotating plate. The two first arc-shaped grooves are inclined, and a fixed column is fixedly connected to one end of each of the two movable plates near the rotating plate. The two fixed columns are slidably connected inside the two first arc-shaped grooves respectively.

[0009] Preferably, the shaft of the rotating plate passes through the top of the outer shell and is fixedly connected to an adjusting plate. The adjusting plate is fan-shaped, and a second arc-shaped groove is provided on the side wall of the adjusting plate. A threaded post is fixedly connected to the top of the outer shell, and the top end of the threaded post is located inside the second arc-shaped groove.

[0010] Preferably, the top of the threaded post is threaded with a bolt cap for limiting the position of the two valve discs.

[0011] Preferably, the top of the adjustment plate is fixedly connected to the side wall near the second arc-shaped groove with an angle scale line.

[0012] Preferably, the top two sides of the adjustment plate are fixedly connected to handles for the user to hold and rotate the plate.

[0013] The beneficial effects of this utility model are: 1. This safe storage and transportation device for octanoyl bromoxybenzonitrile with a sealed valve structure forms a multi-point contact seal by having three sealing rings on the outer wall of the valve disc tightly fit with the outer sealing ring. This not only disperses pressure and extends the service life of the sealing rings, but also enhances the adaptability to pressure fluctuations and temperature changes. Furthermore, the redundant setting of two valve discs provides isolation protection even if a single valve disc seal fails, achieving double protection. The overall structure ensures high sealing performance and safety of octanoyl bromoxybenzonitrile during storage and transportation, effectively preventing leakage of harmful gases or liquids, improving operational reliability, and overcoming the technical defects of existing single valve disc or single sealing ring structures that cannot provide double protection and are prone to leakage after long-term use, thus significantly improving storage and transportation safety.

[0014] 2. This safe storage and transportation device for octanoyl brominated benzonitrile with a sealed valve structure, by smoothly rotating the adjusting plate and rotating plate with a handle, drives the first arc groove, fixed column, moving plate and gear to work together, so that the two valve cores and valve discs rotate synchronously, realizing the smooth opening and closing of the discharge pipe channel. At the same time, only one operation is required, reducing manual operation steps and improving the convenience and efficiency of use. Attached Figure Description

[0020] like Figures 1 to 5 As shown, a safe storage and transportation device for octanoyl bromoxynil with a sealed valve structure includes a storage tank 1. A sealing cover 2 is fixedly installed on the top of the storage tank 1. A discharge pipe 3 for discharging is connected to the bottom of the storage tank 1. A flange 4 is fixedly connected to the outer wall of the end of the discharge pipe 3 away from the storage tank 1. A sealing mechanism for preventing leakage of octanoyl bromoxynil during storage is provided inside the discharge pipe 3. The sealing mechanism includes a valve core 5 rotatably connected between the inner walls of the discharge pipe 3. A valve disc 6 is fixedly connected to the outer wall of each of the two valve cores 5. A sealing outer ring 7 is fixedly connected to the inner wall of the discharge pipe 3 near the outer wall of each of the two valve discs 6. Three sealing rings 8 are fixedly connected to the outer wall of each of the two valve discs 6. When the three sealing rings 8 and the sealing outer rings 7 are on the same vertical line, the outer walls of the three sealing rings 8 are tightly fitted with the inner wall of the sealing outer rings 7 to form a multi-layer seal.

[0021] Further, see attached document. Figures 1 to 5As shown, a housing 9 is fixedly connected to the top of the discharge pipe 3. The shafts of the two valve cores 5 are inserted into the housing 9 and fixedly connected to gears 10. Sealing rings are fixedly connected to the connection points of the two valve cores 5 and the discharge pipe 3. Moving plates 11, which are arranged opposite to each other, are slidably connected to the bottom sides of the inner wall of the housing 9. The moving plates 11 are Z-shaped. Multiple evenly distributed toothed grooves 21 are opened on the side of the moving plates 11 near the gears 10. The gears 10 and the toothed grooves 21 mesh with each other. A rotating plate 12 is rotatably connected to the middle part of the inner wall of the housing 9. The top of the 2 has two first arc-shaped grooves 13, which are inclined. The two movable plates 11 are fixedly connected to the end near the rotating plate 12 with a fixed column 14. The two fixed columns 14 are slidably connected inside the two first arc-shaped grooves 13. The shaft of the rotating plate 12 passes through the top of the outer shell 9 and is fixedly connected to an adjustment plate 15. The adjustment plate 15 is fan-shaped. The side wall of the adjustment plate 15 has a second arc-shaped groove 16. The top of the outer shell 9 is fixedly connected to a threaded column 17, and the top of the threaded column 17 is inside the second arc-shaped groove 16. By rotating the bolt cap 18, the bottom of the bolt cap 18 is removed from the top of the adjusting plate 15, thereby releasing the limiting position on the adjusting plate 15. The bolt cap 18 can be threaded onto the threaded post 17 and abut against the adjusting plate 15 to limit the position, so as to prevent the valve disc 6 from rotating in the sealed state. The operator holds the handle 20 with both hands and drives the adjusting plate 15 and the rotating plate 12 to rotate. The rotating plate 12 drives the first arc groove 13 to rotate in the circumferential direction. The fixed post 14 slides along the first arc groove 13, so that the two moving plates 11 are close to each other. The moving plate 11 drives the gear 10 to rotate through the tooth groove 21, thereby driving the two valve cores 5 inside the discharge pipe 3 to rotate synchronously. The valve core 5 drives the valve disc 6 to rotate and open the discharge pipe 3 channel to release the material. During the reverse operation, the operator rotates the handle 20 in the opposite direction, and the adjustment plate 15 drives the rotating plate 12 and the first arc groove 13 to rotate in the opposite direction. The fixed column 14 slides along the first arc groove 13, so that the two moving plates 11 move away from each other. The moving plate 11 drives the gear 10 and the valve core 5 to rotate synchronously through the tooth groove 21. The valve core 5 drives the valve disc 6 to rotate back to a position parallel to the sealing outer ring 7. The three sealing rings 8 on the outer wall of the valve disc 6 are tightly fitted with the sealing outer ring 7. The sealing outer ring 7 and the sealing ring 8 are made of perfluoroether rubber, which can withstand strong corrosive media such as strong acids, strong alkalis and halogenated organic compounds, and achieve double sealing. The multi-point contact of the three sealing rings 8 not only improves the sealing reliability, disperses pressure, and extends the service life of the sealing rings 8, but also enhances the adaptability to pressure fluctuations and temperature changes. The redundant arrangement of the two valve discs 6 can still provide isolation protection even if the seal of one valve disc 6 fails, ensuring that octanoyl bromoxynil will not leak during storage and transportation, greatly improving the safety and operational reliability of the storage and transportation process, while overcoming the technical defects of existing single valve disc 6 or single sealing ring 8 structures that cannot provide double protection and are prone to leakage after long-term use.

[0022] Further, see attached document. Figure 5 As shown, the top of the threaded column 17 is threaded with a bolt cap 18 for limiting the two valve discs 6, the top of the adjustment plate 15 is fixedly connected to the side wall of the second arc groove 16 with an angle scale line 19, and the top two sides of the adjustment plate 15 are fixedly connected with handles 20 for the user to hold and rotate the rotating plate 12. The top of the threaded column 17 is threaded with a bolt cap 18 for limiting the two valve discs 6. This cap can fix the adjusting plate 15 when the valve discs 6 are in a sealed state, preventing accidental rotation of the valve discs 6 during storage or transportation and thus preventing material leakage and ensuring operational safety. Angle scale lines 19 are set on the top of the adjusting plate 15 near the side wall of the second arc groove 16, allowing the operator to intuitively judge the opening angle of the rotating plate 12 and the valve discs 6, and achieve precise control of the valve disc opening. The handles 20 fixed on both sides of the adjusting plate 15 make it easy for the operator to hold and rotate the rotating plate 12 evenly with both hands, ensuring that the valve core 5 and the valve discs 6 rotate synchronously and smoothly, thereby improving the reliability and safety of operation and effectively preventing the risk of sealing failure or leakage caused by improper operation.
