Description

Technical Field

[0001] This utility model belongs to the field of dimethylamine storage technology, specifically relating to a dimethylamine storage tank leak prevention device. Background Technology

[0002] Dimethylamine is a secondary amine compound, and the container must be kept sealed during storage to prevent its volatilization. In practical applications, the inlet and outlet pipe connections of dimethylamine storage tanks usually need to be sealed to effectively prevent the risk of leakage. Therefore, specially designed anti-leakage devices for dimethylamine storage tanks are particularly important.

[0003] Existing anti-leakage devices for dimethylamine storage tanks typically use rubber gaskets to seal the pipe connections. Although this method can achieve a certain degree of sealing effect, due to the high internal pressure of the storage tank, the sealing ability of the gasket alone is limited. During the feeding and discharging operations, if there is an operational error or the pipe connection is not sealed properly, the dimethylamine vapor in the tank may quickly spray out with liquid, causing a large leak and creating a safety hazard. Utility Model Content

[0004] In view of this, the present invention provides a dimethylamine storage tank anti-leakage device, which can form a secondary anti-leakage capability by setting an anti-leakage mechanism at the pipeline connection, thereby improving the anti-leakage capability, effectively preventing the penetration of dimethylamine gas, and actively offsetting the small gaps caused by temperature changes or pipe deformation, further enhancing the reliability and environmental adaptability of the sealing system.

[0005] To solve the above-mentioned technical problems, this utility model provides a dimethylamine storage tank anti-leakage device, including a storage tank and fixed pipes respectively installed at its inlet and outlet. Each fixed pipe is externally connected to an external pipe, and an anti-leakage mechanism is installed between the fixed pipe and the external connecting pipe. A limiting component for limiting the anti-leakage mechanism is also installed between the fixed pipe and the external connecting pipe. The anti-leakage mechanism includes a first sealing ring installed on the fixed pipe and a second sealing ring installed on each of the external connecting pipes. The second sealing rings abut against adjacent first sealing rings on the same side. The entire structure formed by the second sealing ring and the first sealing ring is located within the adjacent limiting component on the same side, thus improving the anti-leakage capability, effectively preventing the penetration of dimethylamine gas, and actively offsetting the minute gaps caused by temperature changes or pipe deformation, further enhancing the reliability and environmental adaptability of the sealing system.

[0006] The leak prevention mechanism also includes sealing airbags located inside the second and first sealing rings, respectively. The sealing airbags are rubber sealing airbags, which further enhances the reliability and environmental adaptability of the sealing system.

[0007] The cross-section of the contact area between sealing ring 2 and sealing ring 1 has a sawtooth structure, which improves the anti-leakage capability.

[0008] The limiting assembly includes external threaded sleeves that are movably mounted on the fixed pipe, and internal threaded pipes that are movably mounted on the external connecting pipes. The external threaded sleeves are located outside the fixed pipes, and the internal threaded pipes are located outside the external connecting pipes. The external threaded sleeves are threadedly connected to the internal threaded pipes adjacent to each other on the same side. The sealing ring 2 and sealing ring 1 together are located between the external threaded sleeves and internal threaded pipes adjacent to each other on the same side, which allows for flexible operation and installation, and convenient disassembly and maintenance.

[0009] The external threaded sleeve consists of two semi-circular external threaded tubes, which are fixedly connected by several bolts, making it easy for operators to handle.

[0010] The internally threaded pipe consists of two semi-circular internally threaded pipes, which are fixedly connected by several bolts, making it easy for operators to assemble.

[0011] Sealing ring one is a rubber sealing ring one, and sealing ring two is a rubber sealing ring two, which are both elastic and easy for operators to install.

[0012] The beneficial effects of the above-mentioned technical solution of this utility model are as follows:

[0013] 1. The operator first places the rubber sealing ring one and sealing ring two onto the outside of the fixed pipe and connecting pipe respectively. Then, the mating surfaces of sealing ring one and sealing ring two are tightly fitted together. The serrated structure at the contact point forms a physical sealing barrier through interlocking, which significantly improves the anti-leakage capability and effectively prevents the penetration of dimethylamine gas. At the same time, the sealing air bladder is pre-filled with inert gas, which can form a uniform elastic pressure in the contact area, actively offsetting the small gaps caused by temperature changes or pipe deformation, further enhancing the reliability and environmental adaptability of the sealing system.

[0014] 2. The operator places the split external threaded sleeve and internal threaded pipe into the predetermined positions of the fixed pipe and connecting pipe, respectively. Then, the operator performs preliminary pre-tightening with bolt one and bolt two, and then rotates the pipe to ensure precise thread alignment. The tightening force of the threads clamps the sealing assembly as a whole, forming a stable mechanical limit. After the operation is completed, the pipe is locked directly. The pipe can be flexibly installed, disassembled and maintained, significantly reducing the complexity of manual operation. Attached Figure Description

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figure 1-4 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0021] This embodiment provides a leak-proof device for a dimethylamine storage tank, such as... Figure 1-4 As shown: The system includes a storage tank 100 and fixed pipes 300 respectively installed at its inlet and outlet. Each fixed pipe 300 is externally connected to an external connecting pipe 301. An anti-leakage mechanism is provided between the fixed pipe 300 and the external connecting pipe 301. A limiting component is also provided between the fixed pipe 300 and the external connecting pipe 301 to limit the anti-leakage mechanism. The anti-leakage mechanism includes a first sealing ring 200 respectively installed on the fixed pipe 300, and a second sealing ring 201 respectively installed on each of the external connecting pipes 301. The second sealing rings 201 are adjacent to each other on the same side. The sealing ring 200 is in contact with the sealing ring 201. The sealing ring 201 and the sealing ring 200 together are located in adjacent limiting components on the same side. The leak prevention mechanism also includes sealing airbags 202 respectively disposed inside the sealing ring 201 and the sealing ring 200. The sealing airbag 202 is a rubber sealing airbag. The cross-section of the contact point between the sealing ring 201 and the sealing ring 200 is a sawtooth structure. The sealing ring 200 is a rubber sealing ring 1 and the sealing ring 201 is a rubber sealing ring 2. The rubber material of the sealing ring 200 and the sealing ring 201 is elastic.

[0022] First, the rubber sealing ring 200 and sealing ring 201 are respectively fitted onto the outside of the fixed tube 300 and the connecting tube 301. Then, the mating surfaces of sealing ring 200 and sealing ring 201 are tightly fitted together. The serrated structure at the contact point forms a physical sealing barrier through interlocking, which significantly improves the anti-leakage capability and effectively prevents the penetration of dimethylamine gas. At the same time, the sealing airbag 202 is pre-filled with inert gas, which can form a uniform elastic pressure in the contact area, actively offsetting the small gaps caused by temperature changes or tube deformation, further enhancing the reliability and environmental adaptability of the sealing system.

[0023] like Figure 1-4 As shown, the limiting assembly includes external threaded sleeves 400 movably disposed on the fixed tube 300, and internal threaded tubes 401 movably disposed on the external connecting tube 301. The external threaded sleeves 400 are located outside the fixed tube 300, and the internal threaded tubes 401 are located outside the external connecting tube 301. The external threaded sleeves 400 are threadedly connected to the adjacent internal threaded tubes 401 on the same side. The sealing ring 201 and the sealing ring 200 are located between the adjacent external threaded sleeves 400 and the internal threaded tubes 401 on the same side. The external threaded sleeve 400 includes two semi-circular external threaded tubes, which are fixedly connected by several bolts. The internal threaded tube 401 includes two semi-circular internal threaded tubes, which are fixedly connected by several bolts. The internal threads on the inner arc surfaces of the two semi-circular internal threaded tubes form a complete internal thread after they are joined together. The external threads on the two semi-circular external threaded tubes form a complete external thread after they are joined together.

[0024] The operator places two semi-circular external threaded pipes and two semi-circular internal threaded pipes into the predetermined positions of the fixed pipe 300 and the connecting pipe 301, respectively. Then, the operator performs preliminary pre-tightening with bolts one and two. The integrated external threaded sleeve 400 and internal threaded pipe 401 are then rotated to ensure precise thread alignment. The tightening force of the threads clamps the sealing assembly as a whole, forming a stable mechanical limit. After the operation is completed, the assembly is directly locked. This allows for flexible operation and installation, and convenient disassembly and maintenance, significantly reducing the complexity of manual operation.

[0025] The working principle of the dimethylamine storage tank leak-proof device provided by this utility model is as follows: The operator first places the rubber sealing ring 200 and sealing ring 201 onto the outside of the fixing pipe 300 and connecting pipe 301, respectively. Then, the mating surfaces of sealing ring 200 and sealing ring 201 are tightly fitted together. The serrated structure at the contact point forms a physical sealing barrier through interlocking, significantly improving the leak-proof capability and effectively preventing the penetration of dimethylamine gas. Simultaneously, the sealing airbag 202 is pre-filled with inert gas, which can form a uniform elastic pressure in the contact area, actively counteracting the leakage caused by… The minute gaps caused by temperature changes or pipe deformation further enhance the reliability and environmental adaptability of the sealing system. Subsequently, the operator will put the split external threaded sleeve 400 and internal threaded pipe 401 into the predetermined positions of the fixed pipe 300 and the connecting pipe 301, respectively. Then, the bolts 1 and 2 will be used for preliminary pre-tightening. Then, the threads will be precisely aligned by rotation. The tightening force of the threads will be used to clamp the sealing assembly as a whole, forming a stable mechanical limit. After the operation is completed, it can be locked directly. It can be flexibly operated and installed, and disassembly and maintenance are convenient, which significantly reduces the complexity of manual operation.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0027] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
