However, in general fluid circulation, the fluid is usually discharged to the normal environment before being utilized.

Even the supercharging device of an automobile can only recycle a small part of the pressure gas for re-circulation.

[0005] Therefore, the application prospect of the present invention is relatively broad. Summary of the Invention

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] To make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions in the present invention will be clearly and completely described below with reference to the accompanying drawings in the present invention. Apparently, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present invention without creative efforts shall fall within the protection scope of the present invention.

[0019] For ease of explanation and understanding, unless otherwise specified, Figure 1 will be the main object of description.

[0020] Figure 1 As can be seen, P is the pressure value of the pressure chamber 1, P1 is the pressure measurement point at the fluid outlet 1-5 of the pressure chamber 1, P2 is the pressure measurement point at the fluid inlet 1-11 of the pressure chamber 1, and P3 is the pressure measurement point at the reflux outlet 2-2 of the one-way check and reverse return device 2. These pressure measurement points are not the actual structures of the gaseous fluid circulation system, but only labels for easy understanding.

[0021] The pressure chamber 1 is one of the most important core components in the gaseous fluid circulation system.

[0022] Figure 1 As can be seen, the pressure chamber 1 is usually a cylindrical cube, but it can also be other cubes with length, width and height shapes. The pressure chamber 1 is a hollow object with a large internal space. The pressure chamber 1 needs to withstand high pressure, so it is mostly made of strong materials.

[0023] The main switch valve 1-1 is respectively connected to the pressure chamber 1 and the one-way check and reverse return device 2 and can make the two conduct or close. It can also be like Figure 2 as shown, the lower half of the one-way check and reverse return device 2 extends into the pressure chamber 1, and the main switch valve 1-1 enters the pressure chamber 1 and is connected to the one-way check and reverse return device 2. The advantage is that the volume of the entire gaseous fluid circulation system is smaller.

[0024] The reflux conduit 3 is a relatively slender through pipe, which is a dedicated channel for the liquid fluid 102. In addition to being respectively connected to the pressure chamber 1 and the one-way check and reverse return device 2, it can also be connected to the flow valve 1-6 and the load 4. In addition, multiple loads 4 can also be connected in series on the reflux conduit 3.

[0025] As Figure 1 shown, the pressure chamber 1 usually has at least two upper and lower flow ports. The upper flow port is the fluid inlet 1-11 of the pressure chamber 1, which is connected to the one-way check and reverse return device 2 through the main switch valve 1-1. The lower flow port is the fluid outlet 1-5, which is connected to the reflux conduit 3. In addition, the pressure chamber 1 can also be seen to be equipped with a pressure input device 1-2, a safety device (pressure relief) 1-3, etc.

[0026] The pressure chamber 1 is filled with a gaseous fluid 101. The gaseous fluid 101 is a pressure fluid with high compressibility and high expansibility.

[0027] When the main switch valve 1-1 is opened, a passage will be formed between the pressure chamber 1 and the one-way check and reverse device 2.

[0028] The gaseous fluid 101 in the pressure chamber 1 is usually input by a pressure input device 1-2 such as an air compressor, an air tank and other equipment.

[0029] When the pressure of the gaseous fluid 101 in the pressure chamber 1 reaches the set pressure value, the volume of the gaseous fluid 101 increases, trying to occupy more limited space in the pressure chamber 1. It is bound to flow the gaseous fluid 101 from the fluid outlet 1-5 of the pressure chamber 1 into the reflux conduit 3, and the reflux conduit 3 then inputs the gaseous fluid 101 from the reflux inlet 2-1 of the one-way check and reverse device 2 into the one-way check and reverse device 2, so as to reflux back into the pressure chamber 1 through the fluid inlet 1-11 of the pressure chamber 1 again.

[0030] The pressure chamber 1 usually only needs to be processed with a fluid outlet 1-5 at its lower position to connect with the reflux conduit 3. But if necessary, the pressure chamber 1 can also be processed with several fluid outlets 1-5, and these fluid outlets 1-5 can be respectively connected with the same number of independent reflux conduits 3.

[0031] In addition to being able to be respectively connected with multiple reflux conduits 3, several fluid outlets 1-5 of the pressure chamber 1 can also be connected with a reflux conduit 3 with a larger inner diameter.

[0032] Figure 1 As can be seen, the pressure chamber 1 is usually also equipped with accessories such as a pressure input device 1-2, a safety device (pressure relief) 1-3, a flow valve 1-6, etc.

[0033] The one-way check and reverse device 2 is one of the most important core components in the gaseous fluid circulation system.

[0034] The fluid can only flow normally in a set single direction (one-way flow) and cannot flow normally in the opposite direction; and the flow channel of the one-way check and reverse device 2 can restrict the reverse flow of the fluid or at least restrict its flow state and flow rate without installing any form of movable blocking components.

[0035] The one-way check and reverse device 2 shown in the figure is usually a cylindrical cube, but it can also be other cubes with the shape of length, width and height.

[0036] The main flow channel 21-1 inside the one-way check and reverse device 2 is a straight channel with a relatively long length.

[0037] There are several side bends 21-2 and several weir islands 203 that can significantly affect the fluid flow pattern processed in the sprue. Just from the name, it can be known that the one-way check valve 2 is actually a device that allows fluid to flow smoothly in one direction but can prevent reverse flow.

[0038] Specifically, the internal flow path of the one-way check valve 2 is divided into three sections: upper, middle, and lower from top to bottom. The flow paths of the upper and lower sections are both short and smooth, while the flow path of the middle section is long, and several side bends and weir islands are provided on both sides. The fluid either has extremely difficult normal flow or will automatically obtain a certain degree of acceleration in the middle-section flow path, depending on the flow direction of the fluid in the one-way check valve 2: If the fluid flows from A to B as shown, that is, flowing downward in the forward direction, it is not only relatively smooth but may even obtain a certain acceleration; if it flows from B to A, that is, flowing upward in the reverse direction, it is extremely difficult to flow. Figure 3 As shown, when flowing from A to B, that is, flowing downward in the forward direction, it is not only relatively smooth but may even obtain a certain acceleration; if it flows from B to A, that is, flowing upward in the reverse direction, it is extremely difficult to flow.

[0039] The cross-sectional area of the flow path of each section (upper, middle, and lower) of the one-way check valve 2 is quite important for the gaseous fluid circulation system.

[0040] The cross-sectional area of the main flow path in the upper section of the one-way check valve 2 is usually larger than that of the main flow path in the lower section. Of course, the cross-sectional area of the main flow path in the upper section of the one-way check valve can also be equal to or less than that of the main flow path in the lower section; however, the preferred technical solution is that the cross-sectional area of the main flow path in the upper section is larger than that of the main flow path in the lower section.

[0041] The one-way check valve 2 is usually connected to the pressure chamber 1 through the main switch valve 1-1. The return conduit 3 is the return channel between the pressure chamber 1 and the one-way check valve 2. One end of the return conduit 3 is connected to the fluid outlet 1-5 of the pressure chamber 1, and the other end is connected to the return inlet 2-1 of the one-way check valve 2. The load 4 is connected in series on the return conduit 3 between the pressure chamber 1 and the one-way check valve 2, thus forming a complete loop of gaseous fluid.

[0042] The return inlet 2-1 is the upper port of the one-way check valve 2, and gaseous fluid enters the one-way check valve 2 from here. The return outlet 2-2 is the lower port of the one-way check valve 2, and gaseous fluid is discharged or enters the pressure chamber 1 from here.

[0043] The pressure monitoring device 2-3 monitors whether the fluid pressure entering the flow path of the one-way check valve 2 from the return conduit 3 can ensure smooth fluid flow. If it is insufficient, it will feedback to the pressure compensation device 2-4 to start the pressure compensation mechanism to ensure that the forward-flowing fluid in the flow path of the one-way check valve 2 can flow smoothly.

[0044] Since the load 4 may need to adjust the output power, the flow valve 1-6 is usually connected in series on the return conduit 3 between the fluid outlet 1-5 and the load 4.

[0045] Although the main switch valve 1-1 and the flow valve 1-6 are independent components respectively, for the convenience of control, a synchronization mechanism can be installed between them to achieve the synchronous opening and closing of the main switch valve 1-1 and the flow valve 1-6, and the effect will be better.

[0046] Working principle A certain amount of gaseous fluid 101 is input into the pressure chamber 1 to ensure that the gaseous fluid 101 always maintains a constant state and constant quantity. The so-called constant state means that the gaseous fluid 101 always has a set pressure in the pressure chamber 1.

[0047] According to Pascal's theorem, the fluid pressure in a closed container will act uniformly on each point. Therefore, the gaseous fluid 101 that has reached the set pressure value in the pressure chamber 1 will also act uniformly on each point. However, the so-called uniform action on each point mainly refers to the fluid inlet 1-11 and the fluid outlet 1-5 of the pressure chamber 1.

[0048] At this time, the pressure value P of the gaseous fluid 101 is exactly equal to each point or any point in the pressure chamber 1 (the pressure measurement points P1 and P2 are equivalent). As for the measurement point P3 at the outlet 2-2 of the one-way check valve device 2, it may be equal to or different from the pressure value P, the measurement points P1 and P2 in the pressure chamber 1. The key to whether it is "equal" or "unequal" here is the "open" or "closed" state of the main switch valve 1-1.

[0049] If the main switch valve 1-1 is in the "closed" state, the pressure chamber 1 and the one-way check valve device 2 are not connected to each other, and the pressure value at the measurement point P3 should be basically equal to the pressure values at the measurement points P1 and P2 in the pressure chamber 1. If the main switch valve 1-1 is in the "open" state at this time, there are two possibilities, that is, the pressure at the measurement point P3 is equal to or less than the pressure at the measurement points P1 and P2. If the pressure at the measurement point P3 is greater than the pressure at the measurement points P1 and P2, the gaseous fluid 101 should be able to flow back into the pressure chamber 1.

[0050] Actually, once the main switch valve 1-1 is opened, a channel will be immediately formed between the pressure chamber 1 and the one-way check valve device 2, and the gaseous fluid 101 will immediately flow from the fluid inlet 1-11 of the pressure chamber 1 towards the return outlet 2-2 of the one-way check valve device 2, attempting to break through the "defense" of the one-way check valve device 2 and flow upstream into the one-way check valve device 2, and the gaseous fluid 101 originally filled in the one-way check valve device 2 will also immediately flow downward at the same time. Of course, these are just the "trends" of the two at the moment when the main switch valve 1-1 is opened.

[0051] Since enough side bays and weirs have been set in the one-way check valve device 2, the structural resistance of the side bays and weirs makes it difficult for the retrograde gaseous fluid 101 to "flow upstream".

[0052] The gaseous fluid 101 in the pressure chamber 1 will cause the originally occupied space to be compressed due to continuous inflow through the one-way check valve device 2. Therefore, the pressure value P in the pressure chamber 1 increases, forcing the gaseous fluid to flow from the fluid outlet 1-5 to the reflux conduit 3, so as to keep the volume of the gaseous fluid 101 in the pressure chamber 1 constant, maintain a constant pressure, and restore the overall pressure balance. The gaseous fluid 101 flowing from the fluid outlet 1-5 to the reflux conduit 3 will return to the one-way check valve device 2 and then flow downward into the pressure chamber 1. Thus, the cycle is completed.

[0053] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
