Description

Technical Field

[0001] The utility model belongs to the technical field of industrial gas pressure regulation and storage, and particularly relates to an industrial gas pressure regulation and storage system. Background Art

[0002] Industrial gases are generally stored in a single container. Affected by factors such as transportation and environment, the air pressure in the storage container may temporarily increase, which affects the storage safety of industrial gases. Generally, when the air pressure inside the storage container increases, the best way is to relieve the pressure in a timely manner. Since it is an industrial gas, it cannot be directly emptied, and a pressure relief receiving container needs to be set up to receive the gas. The operation process is rather troublesome and the timeliness is poor, which greatly affects the safety of industrial gas storage. Summary of the Invention

[0003] Object of the Invention: In order to overcome the deficiencies in the prior art, the utility model provides an industrial gas pressure regulation and storage system, which connects the gas source storage containers through a gas transmission pipeline to achieve double-container storage, and realizes intercommunication pressure regulation storage of automatic gas conduction from the high-pressure side to the low-pressure side through the pressure regulating valve device on the gas transmission pipeline, thereby improving the storage safety of industrial gases.

[0004] Technical Solution: To achieve the above object, the industrial gas pressure regulation and storage system of the utility model includes a gas source storage container, a gas transmission pipeline, and a pressure regulating valve device; the gas source storage containers are a pair, and this pair of gas source storage containers are connected through a gas transmission pipeline to form a series gas source storage container group; the pressure regulating valve device installed on the gas transmission pipeline includes two states: open valve and closed valve. When there is a gas source pressure difference between this pair of gas source storage containers, the pressure regulating valve device opens the valve to enable industrial gas to flow from the high-pressure side to the low-pressure side through the gas transmission pipeline.

[0005] Further, both ends of the gas transmission pipeline are respectively communicated with this pair of gas source storage containers; when the pressure regulating valve device is in the open valve state, this pair of gas source storage containers conduct gas and communicate with each other through the gas transmission pipeline; when the pressure regulating valve device is in the closed valve state, this pair of gas source storage containers are isolated from each other.

[0006] Further, the pressure regulating valve device includes a valve body, a valve plug, and an elastic support part; the valve plug is axially elastically movably arranged in the valve cavity of the valve body through two elastic support parts symmetrically arranged at its two axial ends; the valve cavity of the valve body includes a small-section valve cavity and two large-section valve cavities symmetrically connected to both ends of the small-section valve cavity;

[0007] When the air pressure at both ends is balanced or the air pressure thrust difference cannot overcome the elastic force of the elastic support part, the valve plug is in a state of blocking the small-section valve cavity;

[0008] When the pressure thrust difference at both ends of the valve plug can overcome the elastic force of the elastic support part, the valve plug is displaced from the high-pressure end to the low-pressure end by the air pressure, so as to release the blockage of the small-section valve cavity by the valve plug.

[0009] Further, the valve plug includes a cylindrical plug and conical plugs symmetrically arranged at both ends of the cylindrical plug. The conical plugs are connected to the elastic support part. When the valve plug is displaced to a state where the cylindrical plug enters the small-section valve cavity, the cylindrical plug seals the small-section valve cavity by sliding. When the valve plug is displaced to a state where the cylindrical plug moves out of the small-section valve cavity, the small-section valve cavity is communicated with the large-section valve cavities at both ends.

[0010] Further, the elastic support part includes a spring and a support frame that are sequentially connected to the conical plug. The support frame is installed on the inner wall of the large-section valve cavity.

[0011] Further, automatic pressure measuring parts are respectively arranged on the gas source storage containers.

[0012] Beneficial effects: The utility model realizes the storage of two containers by connecting the gas source storage containers through a gas transmission pipeline, and realizes the intercommunication pressure regulation storage of automatic gas conduction from the high-pressure side to the low-pressure side through the pressure regulating valve device on the gas transmission pipeline, avoiding the problems of low timeliness of pressure relief and cumbersome operation in the single-container storage of industrial gases, further improving the storage safety of industrial gases, and being suitable for large-scale popularization and application. Description of the Drawings

[0013] Figure 1 It is a schematic diagram of the overall structure of the utility model;

[0014] Figure 2 It is a schematic diagram of a specific embodiment of the utility model in the state of triggering automatic pressure regulation. Detailed Embodiment

[0015] The following further describes the utility model with reference to the drawings.

[0016] Such as Figure 1As shown in the figure, the industrial gas pressure regulating and storage system includes a gas source storage container 1, a gas transmission pipeline 2, and a pressure regulating valve device 3. The gas source storage container 1 is a pair, and this pair of gas source storage containers 1 are connected by a gas transmission pipeline 2 to form a series gas source storage container group. The pressure regulating valve device 3 installed on the gas transmission pipeline 2 has two states: open valve and closed valve. When there is a gas source pressure difference in this pair of gas source storage containers 1, the pressure regulating valve device 3 opens the valve to allow industrial gas to flow from the high-pressure side to the low-pressure side through the gas transmission pipeline 2. More specifically, both ends of the gas transmission pipeline 2 are respectively connected to this pair of gas source storage containers 1. When the pressure regulating valve device 3 is in the open valve state, this pair of gas source storage containers 1 conduct gas and communicate with each other through the gas transmission pipeline 2. When the pressure regulating valve device 3 is in the closed valve state, this pair of gas source storage containers 1 are isolated from each other. The utility model connects the gas source storage container 1 through the gas transmission pipeline 2 to achieve dual-container storage, and realizes the interconnection and pressure regulation storage of automatic gas conduction from the high-pressure side to the low-pressure side through the pressure regulating valve device 3 on the gas transmission pipeline 2, avoiding the problems of low timeliness of pressure relief and cumbersome operation in single-container storage of industrial gas, and further improving the storage safety of industrial gas.

[0017] As Figure 1 shown, the pressure regulating valve device 3 includes a valve body 4, a valve plug 5, and an elastic support part. The valve plug 5 is axially elastically movably arranged in the valve cavity of the valve body 4 through two elastic support parts symmetrically arranged at its two axial ends. The valve cavity of the valve body 4 includes a small-section valve cavity 40 and two large-section valve cavities 41 symmetrically connected to both ends of the small-section valve cavity 40. In the utility model, the movement state of the valve plug 5 is related to the switching between the open valve and the closed valve of the pressure regulating valve device 3, specifically as follows;

[0018] The closed valve working condition of the pressure regulating valve device 3 is: when the valve plug 5 is in a state where the air pressures at both ends are balanced or the air pressure thrust difference cannot overcome the elastic force of the elastic support part, the valve plug 5 is in a state of blocking the small-section valve cavity 40.

[0019] The open valve working condition of the pressure regulating valve device 3 is: when the air pressure thrust difference at both ends of the valve plug 5 can overcome the elastic force of the elastic support part, the valve plug 5 is displaced from the high-pressure end to the low-pressure end by the air pressure to release the blocking of the small-section valve cavity 40 by the valve plug 5, so that the two gas source storage containers 1 are connected and conduct gas through the gas transmission pipeline 2.

[0020] More specifically, the valve plug 5 includes a cylindrical plug 51 and conical plugs 52 symmetrically arranged at both ends of the cylindrical plug 51. The conical plugs 52 are connected to the elastic support portion. When the valve plug 5 is displaced to a state where the cylindrical plug 51 enters the small-section valve cavity 40, the cylindrical plug 51 slides to seal the small-section valve cavity 40. When the valve plug 5 is displaced to a state where the cylindrical plug 51 moves out of the small-section valve cavity 40, the small-section valve cavity 40 communicates with the large-section valve cavities 41 at both ends. The cylindrical plug 51 plays a main blocking role, that is, closing the valve. When the cylindrical plug 51 moves out of the small-section valve cavity 40, the blocking is released, that is, opening the valve. The purpose of arranging the conical plugs 52 on the valve plug 5 is to guide the cylindrical plug 51 to perfectly enter the small-section valve cavity 40 when the valve plug 5 is switched from opening the valve to closing the valve, so as to avoid large fluctuations in the displacement of the cylindrical plug 51 affected by the airflow in the gas transmission pipeline 2 when closing the valve, making it difficult to enter the small-section valve cavity 40.

[0021] The elastic support portion of the present invention includes a spring 6 and a support frame 7 that are sequentially connected to the conical plug 52. The support frame 7 is installed on the inner wall of the large-section valve cavity 41. Both ends of the spring 6 are fixed to the conical plug 52 and the support frame 7 respectively, and the support frame 7 is fixed to the inner wall of the large-section valve cavity 41.

[0022] In order to be able to obtain the internal air pressures of the two gas source storage containers 1 in real time, in the present invention, as Figure 1 shown, automatic pressure measurement portions 10 are respectively provided for the gas source storage containers 1. As Figure 2 shown, the two gas source storage containers 1 of the present invention are respectively a first gas source storage container 1a and a second gas source storage container 1b, and the two automatic pressure measurement portions 10 are respectively a first automatic pressure measurement portion 10a corresponding to the first gas source storage container 1a and a second automatic pressure measurement portion 10b corresponding to the second gas source storage container 1b. The automatic pressure measurement portion 10 is preferably a pressure sensor.

[0023] Next, in conjunction with Figure 2 the pressure regulation and storage principle of the present invention will be briefly described as follows:

[0024] As Figure 2As shown, when the air pressure in the first gas source storage container 1a is higher than that in the second gas source storage container 1b, and the air pressure thrust difference applied to the valve plug 5 from both ends can completely overcome the elastic force provided by the spring 6, the valve plug 5 is pushed by the high-pressure air thrust, causing the valve plug 5 to displace towards the second gas source storage container 1b. When the cylindrical plug 51 moves out of the small-section valve cavity 40, the pressure regulating valve device 3 is switched from the closed valve state to the open valve state, and the small-section valve cavity 40 is communicated with the large-section valve cavities 41 at both ends. The entire gas transmission pipeline 2 is in a conducting state, enabling the first gas source storage container 1a and the second gas source storage container 1b to be connected through the gas transmission pipeline 2. At this time, the industrial gas in the first gas source storage container 1a will flow into the second gas source storage container 1b through the gas transmission pipeline 2 until the air pressures in the first gas source storage container 1a and the second gas source storage container 1b are the same. At this time, the air thrust on the valve plug 5 disappears, and the valve plug 5 resets under the action of the elastic force of the spring 6 until the cylindrical plug 51 of the valve plug 5 moves into the small-section valve cavity 40, and the pressure regulating valve device 3 is switched from the open valve state to the closed valve state.

[0025] The entire pressure regulating process is automatically executed, and the pressure regulation is more timely and simpler, ensuring the safety of industrial gas storage.

[0026] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
