Detailed Description of the Preferred Embodiments

[0026] The following will describe in detail the specific embodiments of the present utility model with reference to the accompanying drawings.

[0027] Referring to Figure 1 and Figure 2 , the present utility model provides a pressure vessel for storing high-pressure industrial gases, including a container body 1. A plurality of partition plates 2 are fixedly connected to the inner wall of the container body 1. The plurality of partition plates 2 divide the interior of the container body 1 into a plurality of gas storage units. A plurality of branch pipelines 5 are fixedly connected to the side wall of the container body 1. The plurality of branch pipelines 5 respectively penetrate into a plurality of storage units. The branch pipelines 5 are communicated with the gas storage units through flow ports 6. A branch gas charging and discharging valve 7 is fixedly connected to the side wall of the branch pipelines 5;

[0028] A main pipeline 3 is fixedly connected inside the container body 1. One end of the main pipeline 3 penetrates outside the container body 1 and is connected with a main gas charging and discharging valve 4. The inside of the main pipeline 3 is communicated with the inside of the plurality of branch pipelines 5. Pipe valves 8 are arranged inside the plurality of branch pipelines 5. The pipe valves 8 are used to control the opening and closing of the connection between the main pipeline 3 and the branch pipelines 5.

[0029] Referring to Figure 3 , the pipe valve 8 includes a lifting assembly 81, a fixed ring seat 82, and a sealing cover 83. The lifting assembly 81 is installed inside the branch pipeline 5. The fixed ring seat 82 is fixedly connected to the inner wall of the main pipeline 3. The output end of the lifting assembly 81 passes through the fixed ring seat 82 and is connected with the sealing cover 83. When the sealing cover 83 is close to the bottom of the fixed ring seat 82, the connection between the main pipeline 3 and the branch pipeline 5 is in a closed state and gas cannot flow through. When the output of the lifting assembly 81 drives the sealing cover 83 to move downward so that the sealing cover 83 does not block the inner cavity of the fixed ring seat 82, the connection between the main pipeline 3 and the branch pipeline 5 is in an open state and gas can flow through normally. The opening and closing switching effect can be achieved by controlling the lifting of the sealing cover 83 through the lifting assembly 81.

[0030] Referring to Figure 4 , the sealing cover 83 includes a main cover body 831. A boss 832 is fixedly connected to the top of the main cover body 831. A sealing ring 833 is arranged on the top of the main cover body 831. The shape and size of the sealing ring 833 are adapted to the shape and size of the inner cavity of the fixed ring seat 82. When different gases are stored in a plurality of gas storage units, if the sealing between the fixed ring seat 82 and the sealing cover 83 is improper, it will cause a mixture of multiple gases inside the main pipeline 3. By setting the boss 832 to fit with the bottom of the fixed ring seat 82 and inserting the sealing ring 833 into the inner cavity of the fixed ring seat 82, the sealing performance between the sealing cover 83 and the fixed ring seat 82 can be improved.

[0031] Referring to Figure 5, the lifting component 81 includes a rotating column 811. A threaded column 812 is fixedly connected to the bottom of the rotating column 811. A moving cylinder 813 is threadedly sleeved on the side wall of the threaded column 812. The bottom end of the moving cylinder 813 passes through the fixed ring seat 82 and is connected to the cover 83. A rotating hole is formed at the top of the branch pipeline 5, and a knob 815 is movably sleeved in the rotating hole. The top end of the rotating column 811 is connected to the knob 815. By rotating the knob 815, the rotating column 811 is driven to rotate. By driving the rotating column 811, the threaded column 812 is driven to rotate. Under the influence of the threaded structure, the positioning strip 816 can move up and down on the side wall of the threaded column 812, so as to achieve the effect of controlling the lifting of the cover 83.

[0032] Refer to Figure 5 , a ring groove is provided on the side wall of the moving cylinder 813, and a sleeve frame 814 is slidably sleeved in the ring groove. The height of the sleeve frame 814 is less than the height of the ring groove. The sleeve frame 814 is fixedly connected to the inner wall of the branch pipeline 5. When the moving cylinder 813 moves down too far, it is easy for the cover 83 to cause pressure on the inner wall of the main pipeline 3, resulting in a risk of damage to the main pipeline 3. By setting the sleeve frame 814 to cooperate with the ring groove on the side wall of the moving cylinder 813, the moving distance of the moving cylinder 813 can be limited, thereby avoiding the cover 83 from causing pressure on the inner wall of the main pipeline 3.

[0033] Refer to Figure 5 , a positioning strip 816 is provided in the ring groove on the side wall of the moving cylinder 813, and a vertical groove is formed in the inner wall of the sleeve frame 814. The positioning strip 816 is slidably sleeved in the vertical groove on the inner wall of the sleeve frame 814. When the threaded column 812 rotates, under the influence of friction, it is easy for the moving cylinder 813 to rotate accordingly, resulting in inability to displace. By setting the positioning strip 816 to cooperate with the vertical groove on the inner wall of the sleeve frame 814, the situation where the moving cylinder 813 rotates can be avoided.

[0034] Refer to Figure 5 , an annular groove is formed on the side wall of the knob 815, and the inner wall of the rotating hole of the branch pipeline 5 is embedded in the annular groove of the knob 815. The inner wall of the rotating hole is connected to the inner wall of the annular groove through a sealing bearing. By setting this structure, the vertical displacement of the knob 815 can be avoided, and the sealing performance can be improved.

[0035] Refer to Figure 6 , 7 , the container body 1 includes an inner shell 11 and an outer shell 12. The inner shell 11 is arranged inside the outer shell 12, and a sandwich layer is provided between the inner shell 11 and the outer shell 12. The side wall of the inner shell 11 is connected to the inner wall of the outer shell 12 through a plurality of shock-absorbing rubber strips 13. Both ends of the inner shell 11 are respectively connected to both ends of the inner wall of the outer shell 12 through two shock-absorbing rubber ring gaskets 14. By setting the shock-absorbing rubber strips 13 and the shock-absorbing rubber ring gaskets 14, the container body 1 can play a shock-absorbing effect when being collided, and is safer when storing flammable and explosive gases.

[0036] Working principle of the present utility model: First, the interior of the container body 1 is divided into multiple independent gas storage units by a number of partition plates 2. The charging and discharging valves 7 can be used to charge and discharge the gas storage units. When discharging, the flow path in the unit storage space is as follows: The gas enters the interior of the branch pipeline 5 through the circulation pipe orifice 6, and the gas in the interior of the branch pipeline 5 is discharged through the charging and discharging valves 7. When charging, the path is opposite. Thus, different types of gases can be stored in a number of independent gas storage units;

[0037] When it is necessary to uniformly charge and discharge a number of independent gas storage spaces, first, the in-pipe valves 8 in a number of branch pipelines 5 are operated to open them, so that the main pipeline 3 is connected to a number of branch pipelines 5. At this time, the gas in a number of gas storage units can enter the interior of the main pipeline 3 through a number of branch pipelines 5, and the gas in the interior of the main pipeline 3 is discharged through the main charging and discharging valve 4. When charging, the path is opposite. Thus, the uniform charging and discharging process is completed.

[0038] The above shows and describes the basic principle, main features and advantages of the present utility model. The present utility model is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed. The scope of protection claimed by the present utility model is defined by the appended claims and their equivalents.
