Description

Technical Field

[0001] This utility model relates to the field of nitrous oxide storage technology, specifically to a high-pressure gas tank for storing nitrous oxide. Background Technology

[0002] Nitrous oxide, also known as "laughing gas," has the chemical formula N₂O. At room temperature, nitrous oxide is a colorless, non-flammable gas with a slightly sweet odor. It has a mild anesthetic effect and can induce laughter. At high temperatures, nitrous oxide is a strong oxidizing agent similar to oxygen. Nitrous oxide has important medical uses, possessing anesthetic and pain-relieving effects. It is widely used as an anesthetic in surgery and dentistry. Nitrous oxide has been included in the World Health Organization's list of essential medicines. It is also used as an oxidizer in rocket propellants and to increase engine power output in racing cars.

[0003] An investigation revealed that a Chinese utility model patent discloses an adjustable high-pressure gas cylinder (publication number: CN216952595U), comprising a pressure cylinder, a pressure regulating valve, a vacuum valve, and a pressure monitoring device. The pressure cylinder has a double-layer structure, with a pressure regulating valve and a vacuum valve installed on it. The pressure regulating valve is connected to the inner cavity of the pressure cylinder, and the vacuum valve is connected to the middle interlayer of the pressure cylinder. A pressure monitoring device is installed inside the pressure cylinder. This utility model can display the gas pressure value inside the cylinder in real time and can adjust the gas pressure inside the cylinder. In addition, this high-pressure gas cylinder has good heat preservation performance and can store and transport gases with high environmental requirements.

[0004] Although the aforementioned patent can quickly adjust the gas pressure inside the cylinder through the design of a pressure regulating valve and other structures to ensure that the gas pressure value inside the cylinder does not exceed the cylinder's tolerance value, thus ensuring the safety and stability of the high-pressure gas cylinder, the pressure regulating valve still requires manual adjustment of the pressure inside the high-pressure gas cylinder according to the pressure gauge. This may result in untimely pressure adjustment inside the high-pressure gas cylinder, posing a potential hazard.

[0005] Therefore, this invention provides a high-pressure gas tank for storing nitrous oxide to solve the above problems. Utility Model Content

[0006] (a) Technical problems to be solved

[0007] This invention provides a high-pressure gas tank for storing nitrous oxide, which aims to solve the problems mentioned in the background art.

[0008] (II) Technical Solution

[0009] To achieve the above objectives, the present invention provides the following technical solution: a high-pressure gas tank for storing nitrous oxide, comprising a supporting base plate and an installation groove formed on the upper surface of the supporting base plate, wherein a supporting recovery mechanism is installed inside the installation groove, and a storage mechanism is installed inside the installation groove;

[0010] The storage mechanism includes a gas storage tank inserted into the mounting slot. A compression plate is slidably connected inside the gas storage tank. Support springs are fixedly connected in a ring array on the lower surface of the compression plate. The support springs are fixedly connected to the inner wall of the gas storage tank. Two corresponding communicating slots are formed on the inner wall of the gas storage tank. An arc-shaped plate is slidably connected inside the communicating slot. The arc-shaped plate corresponds to the compression plate. An exhaust slot is formed in a ring array on the inner wall of the communicating slot. The exhaust slot communicates with the mounting slot. A spring assembly is fixedly connected to the inner bottom wall of the communicating slot. The spring assembly is fixedly connected to the arc-shaped plate.

[0011] As a preferred technical solution of this application, the storage mechanism further includes a safety valve fixedly connected to the surface of the gas storage tank, an overpressure relief valve fixedly connected to the other side of the surface of the gas storage tank, and a pressure gauge fixedly connected to the upper surface of the gas storage tank.

[0012] As a preferred technical solution of this application, the support and recycling mechanism includes fixed plates that are fixedly connected to the inner wall of the mounting groove in a ring array, and a rotating plate is rotatably connected to the opposite sides of each pair of fixed plates through a rotating shaft. The rotating plate is rotatably connected to the inside of the mounting groove.

[0013] As a preferred technical solution of this application, the supporting recycling mechanism further includes a movable plate that is attached to the surface of the rotating plate, and two arc-shaped sealing plates are fixedly connected to one side of several of the movable plates, the arc-shaped sealing plates corresponding to the gas storage tank.

[0014] As a preferred technical solution of this application, the support and recycling mechanism further includes a storage groove opened inside the installation groove, the arc-shaped sealing plate is slidably connected to the inside of the storage groove, and the outer arc surface of the arc-shaped sealing plate is fixedly connected with a return spring in a ring array.

[0015] As a preferred technical solution of this application, the mounting groove has two corresponding air vents inside, and the air vents correspond to the exhaust groove.

[0016] (III) Beneficial Effects

[0017] By designing storage mechanisms and other structures, when the internal pressure of the gas storage tank becomes too high, a safety valve is used to discharge the gas, thereby changing the internal pressure of the gas storage tank. At the same time, the overpressure relief valve allows the gas storage tank to respond to pressure changes in a shorter time, making the gas storage tank more stable during use. Furthermore, when the safety valve and overpressure relief valve cannot be adjusted quickly, nitrous oxide drives the extrusion plate to move, which in turn pushes the arc plate to move. This causes the arc plate to stop sealing the connecting groove, allowing the nitrous oxide in the gas storage tank to be discharged into the installation groove, thus enabling a rapid change in the internal gas pressure of the gas storage tank.

[0018] By incorporating a support and recovery mechanism, and through the interaction of the vent and exhaust channel, the discharged nitrous oxide is recovered into the interior of the support base plate. A gas storage tank is then inserted into the mounting slot, causing the gas storage tank to drive a rotating plate. This rotating plate, in turn, causes a sealing arc plate to seal the mounting slot, preventing excessive waste of nitrous oxide. Simultaneously, the interaction between the spring assembly and the support spring allows the compression plate to slide inside the gas storage tank, resetting the arc plate and preventing further discharge of nitrous oxide. This allows the high-pressure nitrous oxide storage tank to continue to be used, making its operation more convenient. Attached Figure Description

Detailed Implementation

[0026] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] This utility model provides a high-pressure gas storage tank for nitrous oxide, such as... Figures 1-5 As shown, the nitrous oxide storage high-pressure gas tank includes a supporting base plate 1 and an installation groove 2 formed on the upper surface of the supporting base plate 1. A support and recovery mechanism is installed inside the installation groove 2. The support and recovery mechanism includes fixed plates 12 arranged in a ring array and fixedly connected to the inner wall of the installation groove 2. A rotating plate 13 is rotatably connected to the opposite sides of every two corresponding fixed plates 12 through a rotating shaft. The rotating plate 13 is rotatably connected to the inside of the installation groove 2. The support and recovery mechanism also includes a movable plate 14 that is attached to the surface of the rotating plate 13. Two arc-shaped sealing plates 15 are fixedly connected to one side of several movable plates 14. The gas storage tank 3 is inserted into the inside of the installation groove 2, so that the gas storage tank 3 pushes the rotating plate 13 to rotate, so that the rotating plate 13 pushes the movable plate 14 to move, thereby bringing the two arc-shaped sealing plates 15 closer to each other.

[0028] The arc-shaped sealing plate 15 corresponds to the gas storage tank 3. The supporting recovery mechanism also includes a storage groove 16 opened inside the installation groove 2. The arc-shaped sealing plate 15 is slidably connected to the inside of the storage groove 16. When the arc-shaped sealing plates 15 approach each other, they fit together with the gas storage tank 3, sealing the installation groove 2 and supporting the gas storage tank 3, making the gas storage tank 3 more stable during use. The outer arc surface of the arc-shaped sealing plate 15 is fixedly connected with a return spring 17 in a ring array. With the setting of the return spring 17, the arc-shaped sealing plate 15 can not only automatically return after use, but also drive the rotating plate 13 to return, making the gas storage tank 3 more convenient to use.

[0029] The installation slot 2 is equipped with a storage mechanism, which includes a gas storage tank 3 inserted into the installation slot 2. A compression plate 4 is slidably connected inside the gas storage tank 3. A support spring 5 is fixedly connected in a ring array on the lower surface of the compression plate 4. The support spring 5 is fixedly connected to the inner wall of the gas storage tank 3. Two corresponding connecting slots 6 are opened on the inner wall of the gas storage tank 3. An arc plate 7 is slidably connected inside the connecting slot 6. The arc plate 7 corresponds to the compression plate 4. An exhaust slot 8 is opened in a ring array on the inner wall of the connecting slot 6. The exhaust slot 8 is connected to the installation slot 2. When the safety valve 9 and the overpressure relief valve 10 cannot quickly adjust the pressure, nitrous oxide pushes the compression plate 4 to move downward, so that the compression plate 4 drives the arc plate 7 to slide inside the connecting slot 6. Thus, the arc plate 7 no longer seals the connecting slot 6, so that nitrous oxide is discharged through the connecting slot 6 and the exhaust slot 8, thereby quickly adjusting the pressure in the gas storage tank 3.

[0030] A spring assembly 18 is fixedly connected to the inner bottom wall of the connecting groove 6. The spring assembly 18 is fixedly connected to the arc plate 7. When the gas pressure is adjusted, the extrusion plate 4 slides inside the gas storage tank 3 through the cooperation of the spring assembly 18 and the support spring 5, thereby resetting the arc plate 7, so that nitrous oxide is no longer discharged, and the nitrous oxide storage high-pressure gas tank can continue to be used.

[0031] The storage mechanism also includes a safety valve 9 fixedly connected to the surface of the gas storage tank 3, and an overpressure relief valve 10 fixedly connected to the other side of the surface of the gas storage tank 3. When the gas storage tank 3 stores nitrous oxide and the pressure in the gas storage tank 3 becomes too high, the pressure in the gas storage tank 3 is regulated by the cooperation of the safety valve 9 and the overpressure relief valve 10, so that the gas storage tank 3 is more stable and safer during use.

[0032] A pressure gauge 11 is fixedly connected to the upper surface of the gas storage tank 3. The pressure gauge 11 is set to monitor the gas pressure inside the gas storage tank 3. Two corresponding vent holes 19 are opened inside the mounting groove 2. The vent holes 19 correspond to the exhaust groove 8. Two collection grooves connected to the vent holes 19 are opened inside the support base plate 1. Through the setting of the vent holes 19, the nitrous oxide discharged from the exhaust groove 8 is injected into the interior of the support base plate 1 and the nitrous oxide enters the interior of the collection groove, thereby avoiding excessive waste of nitrous oxide.

[0033] Specifically, when using this nitrous oxide storage high-pressure gas tank: the gas storage tank 3 is inserted into the installation groove 2, causing the gas storage tank 3 to push the rotating plate 13 to rotate, which in turn pushes the moving plate 14 to move, thereby bringing the two arc-shaped sealing plates 15 closer together and making them fit against the gas storage tank 3. This seals the installation groove 2 while supporting the gas storage tank 3, making the gas storage tank 3 more stable during use.

[0034] When the pressure in the gas storage tank 3 becomes too high due to the storage of nitrous oxide, the pressure in the gas storage tank 3 is regulated by the cooperation of the safety valve 9 and the overpressure relief valve 10, making the gas storage tank 3 more stable and safe to use. When the safety valve 9 and the overpressure relief valve 10 cannot quickly regulate the pressure, the nitrous oxide pushes the extrusion plate 4 downward, causing the extrusion plate 4 to drive the arc plate 7 to slide inside the connecting groove 6. This causes the arc plate 7 to no longer seal the connecting groove 6, allowing the nitrous oxide to be discharged through the connecting groove 6 and the exhaust groove 8, thereby quickly adjusting the pressure in the gas storage tank 3. At the same time, through the setting of the vent hole 19, the nitrous oxide discharged from the exhaust groove 8 is injected into the interior of the support base plate 1, thereby avoiding excessive waste of nitrous oxide.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
