Description

Technical Field

[0001] This utility model relates to the field of natural gas storage technology, specifically a gas storage cylinder with an adjustable valve opening. Background Technology

[0002] With the increasing global demand for clean energy, the proportion of gaseous energy sources such as natural gas and hydrogen in the energy mix is ​​gradually rising. Hydrogen, as a high-calorific-value, widely available, and clean energy source, is considered an important way to solve the energy crisis and environmental problems, while natural gas, as a relatively clean fossil fuel, also plays a vital role in energy supply. This makes gas storage technology a key link in ensuring a stable energy supply. From traditional underground gas storage facilities to the coexistence of various gas storage methods such as compressed natural gas (CNG) cylinders and liquefied natural gas (LNG) tanks, gas storage technology is constantly developing and innovating. Gas cylinder banks, as a common gas storage method, have advantages such as high flexibility and adaptability, and are widely used in distributed energy systems, transportation, and other fields.

[0003] The existing publication CN213576775U discloses a liquefied natural gas (LNG) extraction cylinder structure, including a first outer shell, a second outer shell inside the first outer shell, and a gas cylinder inside the second outer shell. Compared to existing LNG extraction cylinder structures, this structure significantly reduces the cylinder's volume, allowing for easy movement and facilitating LNG extraction. It solves the problem of existing LNG extraction cylinder structures being too large to carry and move, causing inconvenience during extraction and storage, affecting extraction efficiency, and making them unusable. By incorporating a first and second insulation layer, the structure effectively enhances the insulation performance of the LNG extraction cylinder, offering advantages such as good thermal performance, easy installation, rain and dust protection, and automatic heat dissipation and dehumidification based on temperature and humidity conditions.

[0004] Natural gas is stored in gas cylinders, which are equipped with valves to release and transport the natural gas. However, in the current gas cylinders, it is not easy to control the opening degree of the valve when it is opened. After turning the valve, the opening and closing of the valve depends on the user's turning force and the number of turns. This kind of turning makes it difficult to control the opening degree of the valve, and it is not possible to control the flow rate of natural gas output after the valve is opened by controlling the opening degree.

[0005] Therefore, those skilled in the art have provided a gas storage cylinder with an adjustable valve opening to solve the problems mentioned in the background art. Utility Model Content

[0006] The purpose of this invention is to provide a gas storage cylinder with an adjustable valve opening, so as to solve the problem mentioned in the background art that the valve opening of existing gas storage cylinders is not easy to adjust during use.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] An adjustable valve opening gas cylinder includes: a gas cylinder body, an air inlet integrally connected to the top of the gas cylinder body, a connecting pipe connected to the upper flange of the air inlet, a sealing flange installed at the upper end of the connecting pipe, a valve installed at the upper end of the sealing flange, a ring sleeve installed on the outer side of the valve, an equal-separation plate fixedly installed on the surface of the ring sleeve, a time-delay switch installed on the surface of the equal-separation plate, an indicator light installed on the outer wall of the equal-separation plate, a Hall sensor installed on the surface of the valve, a connecting rod fixedly connected to the bottom of the valve, and an elastic lever fixedly connected to the lower end of the connecting rod.

[0009] As a further embodiment of this utility model: the equal-separation plates are arranged in a ring about the symmetrical center line of the ring sleeve, and twelve sets of equal-separation plates are arranged in a ring.

[0010] As a further improvement of this utility model: the equal-separation plates are divided into twelve groups, and the angle between adjacent equal-separation plates is thirty degrees.

[0011] As a further improvement of this utility model: the valve is connected to the elastic lever via a connecting rod, and the length of the elastic lever is one-third of the length of the equal-separation plate.

[0012] As a further improvement of this utility model, the delay switch and the indicator light are electrically connected.

[0013] As a further improvement of this utility model: the delay switch and the signal light are set in a one-to-one correspondence, and the delay switch and the signal light are set in a one-to-one correspondence with the equal division plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] The valve is connected to the air inlet on the gas cylinder body via a sealing flange. A ring is installed on the outside of the air inlet, and the surface of the ring is circumferentially distributed with equally spaced dividing plates. The ring is 360 degrees in circumference, and there are twelve sets of equally spaced dividing plates, with a 30-degree interval between the first and second sets. The equally spaced dividing plates are evenly distributed circumferentially on the surface of the ring, dividing the 360 ​​degrees into twelve 30-degree intervals. The valve is connected to a flexible lever via a connecting rod. In this way, when the valve is turned, the flexible lever moves within the equally spaced dividing plates. Furthermore, utilizing the elasticity of the flexible lever, it can pass over the equal-separation plates and enter the next set of equal-separation plates. Each time it passes over a set of equal-separation plates, the flexible lever will touch the delay switch, which will trigger the indicator light. The delay switch is set so that the indicator light stays on for three to five seconds. Based on the number of indicator lights lit and the equal-separation plates are set at equal intervals, the valve's turning degree can be determined by superposition, making operation easier. At the same time, a Hall sensor is installed, which will more accurately sense the valve's opening degree when the valve is rotated. Attached Figure Description

[0021] 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.

[0022] Please see Figures 1-4This utility model provides a gas cylinder with an adjustable valve opening, comprising: a gas cylinder body 1, an air inlet 2 integrally connected to the top of the gas cylinder body 1, a connecting pipe 3 connected to the upper flange of the air inlet 2, a sealing flange 4 installed at the upper end of the connecting pipe 3, a valve 6 installed at the upper end of the sealing flange 4, a ring sleeve 5 installed on the outside of the valve 6, an equal-separation plate 501 fixedly installed on the surface of the ring sleeve 5, a time delay switch 502 installed on the surface of the equal-separation plate 501, and a signal light 503 installed on the outer wall of the equal-separation plate 501. The time delay switch 502 and the signal light 503 are electrically connected, and the time delay switch 502 and the signal light 503 are configured in a one-to-one correspondence, and the time delay switch 502 and the signal light 503 correspond one-to-one with the equal-separation plate 501.

[0023] Specifically, the delay switch 502 triggers the signal light 503 through a control circuit. Its core is achieved through the coordinated operation of a trigger module, a delay module, and an execution module. When the elastic lever 602 touches the metal plate of the delay switch 502, the charge changes the capacitance between the electrodes or forms a weak current path. The induced signal triggers the transistor / field-effect transistor to conduct instantaneously, activating the subsequent circuitry. When the elastic lever 602 leaves, the capacitor slowly discharges through the resistor, the voltage gradually decreases, and the power supply to the signal light 503 is cut off. When the valve 6 is turned off, the light goes out. Each set of equal intervals plate 501 is electrically equipped with a time delay switch 502 and an indicator light 503. When the valve 6 is turned, the elastic lever 602 moves between the equal intervals plate 501 and, using the elasticity of the elastic lever 602, can pass over the equal intervals plate 501 to enter the next set of equal intervals plate 501. Each time it passes over a set of equal intervals plate 501, the elastic lever 602 will touch the time delay switch 502, and the time delay switch 502 will trigger the indicator light 503.

[0024] A Hall sensor 7 is installed on the surface of valve 6. A connecting rod 601 is fixedly connected to the bottom of valve 6. An elastic lever 602 is fixedly connected to the lower end of the connecting rod 601. The equal-separation plates 501 are arranged in a ring about the symmetrical center line of the ring 5. Twelve groups of equal-separation plates 501 are arranged in a ring. The angle between adjacent equal-separation plates 501 is thirty degrees. Valve 6 is connected to the elastic lever 602 through the connecting rod 601. The length of the elastic lever 602 is one-third of the length of the equal-separation plate 501.

[0025] Specifically, the surface of the ring 5 is circumferentially distributed with equally spaced dividing plates 501. The circumference of the entire ring 5 is 360 degrees. There are twelve sets of equally spaced dividing plates 501, each set separated by 30 degrees. That is, the distance from one set of equally spaced dividing plates 501 to the next set is 30 degrees. These equally spaced dividing plates 501 are evenly distributed in a ring on the surface of the ring 5, dividing the 360 ​​degrees into twelve 30-degree intervals. The valve 6 is connected to the elastic lever 602 via a connecting rod 601. When the valve 6 is turned, the elastic lever 602 moves within the intervals divided by the equally spaced dividing plates 501. Each time the lever 602 is turned, the elastic lever 602 moves within the intervals divided by the equally spaced dividing plates 501. When the elastic lever 602 moves from one set of equal-separation plates 501 to the next set of plates, the elastic lever 602 will touch the corresponding delay switch 502 on the equal-separation plate 501. After the delay switch 502 is triggered, an indicator light 503 will be lit. Since the equal-separation plates 501 are set at equal intervals, the number of indicator lights 503 lit can be used to determine the opening degree of valve 6, which makes the operation more intuitive and simple. In addition, a Hall sensor 7 is installed. When valve 6 is rotating, the Hall sensor 7 can accurately sense the opening degree of valve 6, further improving the accuracy of valve 6 opening.

[0026] The working principle of this utility model is as follows:

[0027] When using this utility model, the user can control the flow rate in the gas storage cylinder by rotating the valve 6. During the rotation of the valve 6, the connecting rod 601 fixedly installed on the valve 6 will move accordingly, thereby driving the elastic lever 602 to move between the equal-separation plates 501. Whenever the elastic lever 602 moves from one equal-separation plate 501 to the next, it will trigger the delay switch 502 on the equal-separation plate 501. After the delay switch 502 is triggered, after a short delay, the indicator light 503 corresponding to the equal-separation plate 501 will be lit. In this way, by observing the number and position of the indicator lights 503, the user can intuitively understand the opening degree of the valve 6, thereby achieving precise control of the gas flow rate. The setting of the Hall sensor 7 further improves the accuracy of the valve 6 opening degree control. When the valve 6 is turned, the opening degree of the valve 6 is detected by sensing the change of magnetic field.

[0028] 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.
