Description

Technical Field

[0001] This utility model relates to the field of pressure vessels, and in particular to a low-temperature vacuum high-strength pressure vessel. Background Technology

[0002] Low-temperature vacuum high-strength pressure vessels are a special type of pressure vessel that combines multiple characteristics such as low temperature, vacuum, and high strength. They are widely used in scientific research, medicine, aerospace and other fields.

[0003] When using cryogenic vacuum high-pressure vessels, gas is introduced into the tank through an inlet pipe for storage, and then discharged through an outlet pipe when needed. When the inlet pipe is connected to an external pipeline, the connection is prone to loosening under stress, which can cause gas from the inlet pipe to enter the tank, thus affecting the performance of the pressure vessel. Utility Model Content

[0004] The technical problem this invention aims to solve is that when the air inlet pipe is connected to the external pipe, the connection is prone to loosening under stress, which can cause gas from the air inlet pipe to reach the inside of the tank, thus affecting the performance of the pressure vessel.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a low-temperature vacuum high-strength pressure vessel, including a tank body and an installation assembly. The upper end of the tank body is provided with an air inlet pipe, and the lower end of the tank body is provided with an air outlet pipe. The tank body is provided with a reinforcement device by means of the installation assembly, and the reinforcement device reinforces the connection between the air inlet pipe and the external pipe.

[0006] The effect achieved by the above components is as follows: when using a low-temperature vacuum high-pressure vessel, gas is introduced into the tank through the inlet pipe for storage. At this time, a reinforcement device is used to reinforce the connection between the inlet pipe and the external pipe. Then, when the gas is used, it is output through the outlet pipe.

[0007] Preferably, the reinforcement device includes a placement plate, a threaded rod rotatably connected inside the placement plate, the two ends of the threaded rod having opposite threads, a movable plate threadedly connected to both sides of the threaded rod, a reinforcement plate fixedly connected to one side of the movable plate, the size of the reinforcement plate being adapted to the size of the air intake pipe, and an operating block fixedly connected to one side of the threaded rod.

[0008] The aforementioned components achieve the following effects: When using the air inlet pipe, the operating block can be rotated to make the threaded rod rotate inside the placement plate. Then, the threaded rod drives the moving plates at both ends to move closer to each other. Next, the reinforcing plate abuts and fixes the air inlet pipe and the external pipe, thus completing the reinforcement between the air inlet pipe and the external pipe. By using the reinforcement device, the connection between the air inlet pipe and the external pipe can be reinforced, preventing the connection from loosening under stress when the air inlet pipe and the external pipe are connected, which would affect the gas from the air inlet pipe reaching the inside of the tank, thereby improving the performance of the pressure vessel.

[0009] Preferably, a limiting rod is fixedly connected to one side of the placement plate, and one side of the limiting rod is slidably connected to the movable plate.

[0010] The effect achieved by the above components is to limit the movement trajectory of the moving plate by using the limit rod, so that the moving plate can move more stably.

[0011] Preferably, a reinforcing plate is fixedly connected to one side of the movable plate, and one side of the reinforcing plate is fixedly connected to the reinforcing plate.

[0012] The effect achieved by the above components is to improve the connection strength between the moving plate and the reinforcing plate by using the reinforcing plate, and to prevent deformation of the connection between the moving plate and the reinforcing plate under stress.

[0013] Preferably, a rubber pad is fixedly connected to the side of the reinforcing plate near the air intake pipe, and the size of the rubber pad is adapted to the size of the reinforcing plate.

[0014] The effect achieved by the above components is to increase the friction between the reinforcing plate and the intake pipe by using rubber pads, so that the reinforcing plate can better fix the intake pipe.

[0015] Preferably, the mounting assembly includes a mounting plate, one side of which is fixedly connected to the tank body, a bolt is threaded into one side of the mounting plate, a base plate is threaded into one side of the bolt, and one side of the base plate is fixedly connected to the placement plate.

[0016] The effect achieved by the above components is as follows: when using the reinforcement device, the base plate can be moved so that one side of the base plate can be inserted into the mounting plate. Then, the bolts can be rotated so that the bolts pass through the mounting plate and are fixed to the base plate, thus completing the fixation of the base plate position. By using the mounting components, the reinforcement device can be quickly fixed to one side of the mounting plate, making it convenient for operators to use the reinforcement device subsequently.

[0017] Preferably, a positioning plate is fixedly connected to one side of the mounting plate, and the size of the positioning plate is fixedly connected to the base plate.

[0018] The effect achieved by the above components is to quickly locate the position of the base plate by using the positioning plate, which then facilitates the operator to fix the base plate in place.

[0019] Preferably, an inclined plate is fixedly connected to one side of the mounting plate, and the inclined plate is inclinedly disposed on one side of the mounting plate.

[0020] The effect achieved by the above components is to guide the position of the base plate by using the inclined plate, making it easier for the base plate to reach the interior of the mounting plate.

[0021] In summary, the beneficial effects of this utility model are as follows:

[0022] By using a reinforcement device, the connection between the air inlet pipe and the external pipe can be strengthened to prevent the connection from loosening under stress when the air inlet pipe and the external pipe are connected, which would affect the gas from the air inlet pipe reaching the inside of the tank, thereby improving the performance of the pressure vessel.

[0029] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0030] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" or "linked" should be interpreted broadly. For example, it can refer to a fixed connection, a detachable connection, or an integral connection; it can refer to a mechanical connection or an electrical connection; it can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0031] Figures 1 to 4 The illustrated cryogenic vacuum high-pressure vessel includes a tank body 1 and an installation assembly 3. The upper end of the tank body 1 is provided with an inlet pipe 4, and the lower end is provided with an outlet pipe 5. The tank body 1 is equipped with a reinforcing device 2 via the installation assembly 3, which reinforces the connection between the inlet pipe 4 and the external pipeline. When using the cryogenic vacuum high-pressure vessel, gas is introduced into the tank body 1 through the inlet pipe 4 for storage. The reinforcing device 2 reinforces the connection between the inlet pipe 4 and the external pipeline. When gas is needed, it is output through the outlet pipe 5.

[0032] Figures 1 to 4 The reinforcement device 2 shown includes a placement plate 21, with a threaded rod 22 rotatably connected inside the placement plate 21. The threaded rod 22 has opposite threads at both ends, and movable plates 23 are threadedly connected to both sides of the threaded rod 22. A reinforcement plate 24 is fixedly connected to one side of the movable plate 23, and the size of the reinforcement plate 24 is adapted to the size of the air inlet pipe 4. An operating block 25 is fixedly connected to one side of the threaded rod 22. When using the air inlet pipe 4, the operating block 25 can be rotated to make the threaded rod 22 rotate inside the placement plate 21. Then, the threaded rod 22 drives the movable plates 23 at both ends to move closer together. Next, the reinforcement plate 24 abuts and fixes the air inlet pipe 4 to the external pipe, thus completing the reinforcement between the air inlet pipe 4 and the external pipe. By using the reinforcement device 2, the connection between the air inlet pipe 4 and the external pipe can be reinforced, preventing the connection from loosening under stress when the air inlet pipe 4 is connected to the external pipe, which would affect the gas reaching the tank 1 from the air inlet pipe 4, thereby improving the performance of the pressure vessel.

[0033] Figures 1 to 4A limiting rod 26 is fixedly connected to one side of the placement plate 21, and one side of the limiting rod 26 is slidably connected to the moving plate 23. The limiting rod 26 restricts the movement trajectory of the moving plate 23, making its movement more stable. A reinforcing plate 27 is fixedly connected to one side of the moving plate 23, and one side of the reinforcing plate 27 is fixedly connected to the reinforcing plate 24. The reinforcing plate 27 increases the connection strength between the moving plate 23 and the reinforcing plate 24, preventing deformation at the connection point. A rubber pad 28 is fixedly connected to the side of the reinforcing plate 24 near the intake pipe 4, and the size of the rubber pad 28 is compatible with the size of the reinforcing plate 24. The rubber pad 28 increases the friction between the reinforcing plate 24 and the intake pipe 4, allowing the reinforcing plate 24 to better secure the intake pipe 4.

[0034] Figures 1 to 4 The mounting assembly 3 shown includes a mounting plate 31, one side of which is fixedly connected to the tank body 1. A bolt 32 is threaded into one side of the mounting plate 31, and a base plate 33 is threaded into one side of the bolt 32. One side of the base plate 33 is fixedly connected to the placement plate 21. When using the reinforcement device 2, the base plate 33 can be moved so that one side of the base plate 33 inserts into the mounting plate 31. Then, the bolt 32 is rotated to pass through the mounting plate 31 and fix it to the base plate 33, thus completing the fixation of the base plate 33. By using the mounting assembly 3, the reinforcement device 2 can be quickly fixed to one side of the mounting plate 31, facilitating subsequent use by the operator.

[0035] Figures 1 to 4 A positioning plate 34 is fixedly connected to one side of the mounting plate 31, and the dimensions of the positioning plate 34 are fixedly connected to the base plate 33. The positioning plate 34 is used to quickly position the base plate 33, facilitating subsequent fixation by the operator. An inclined plate 35 is fixedly connected to one side of the mounting plate 31, and the inclined plate 35 is angled to one side of the mounting plate 31. The inclined plate 35 is used to guide the position of the base plate 33, making it easier for the base plate 33 to reach the interior of the mounting plate 31.

[0036] Working Principle: When using a cryogenic vacuum high-pressure vessel, gas is introduced into tank 1 through inlet pipe 4 for storage. A reinforcing device 2 reinforces the connection between inlet pipe 4 and the external pipe. Gas is then output through outlet pipe 5. When using inlet pipe 4, the operating block 25 can be rotated, causing the threaded rod 22 to rotate inside the placement plate 21. The threaded rod 22 then drives the moving plates 23 at both ends to move closer together. The reinforcing plate 24 then abuts and fixes the inlet pipe 4 to the external pipe, thus reinforcing the connection between them. By using the reinforcing device 2, the connection between inlet pipe 4 and the external pipe is reinforced, preventing loosening under stress during use and ensuring gas reaches the tank 1, thereby improving the pressure vessel's performance.

[0037] When using the reinforcement device 2, the base plate 33 can be moved so that one side of the base plate 33 is inserted into the mounting plate 31. Then, the bolt 32 is rotated so that the bolt 32 passes through the mounting plate 31 and is fixed to the base plate 33. Then the position of the base plate 33 is fixed. By using the mounting assembly 3, the reinforcement device 2 can be quickly fixed to one side of the mounting plate 31, which makes it convenient for the operator to use the reinforcement device 2 in the future.

The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
