The present invention discloses a high speed manual internal sliding valve for air or other gases and a method of manufacturing the same, and simply describes a valve body for releasing pressurized air. However, in actual practice, various embodiments of the disclosed manual quick release valve can be used to maintain and release any type of gas, ie, any type of gaseous species such as air, oxygen, carbon dioxide, nitrogen, and the like. The term "gas" as used in the present invention means a substance in a gaseous state, not a gasoline.

1 discloses an exploded perspective view of a manual internal sliding valve body 100 in accordance with various embodiments of the present disclosure, revealing four components, namely a chamber tube body 101, a sliding sleeve 103, a compression spring 105 and an end. Cover 107. Typically, the chamber tube 101 is fitted in an opening A1 for use in a pressure tank A container (as in Figures 6 and 7). And a part of the chamber body 101 (for example, the leftmost portion in Fig. 1, the left side of the "L" shaped hole) is located inside the pressure tank A, and the other portion (the rightmost portion) of the chamber tube 101 is from The tank extends out of the exterior to expel and release pressurized gas from the tank into the atmosphere. The chamber body 101 may have an externally threaded portion in the internally threaded bore corresponding to the opening A1 of the pressure tank A. 2A-A reveal the male threaded portion between the "L" shaped bore and the slot of the chamber body 101.

The outer diameter D of the sliding sleeve 103 is slightly smaller than the inner diameter d of the chamber tube body 101, so that the sliding sleeve 103 can fit inside the chamber tube body 101 and slide back and forth similarly to the piston sliding in the cylinder. . The compression spring 105 is fitted in the chamber tube body 101 between the sliding sleeve 103 and the end cap 107. If the new high speed gas valve is in the closed position, the sliding sleeve 103 pushes downward toward the end cap 107 and against the compression spring 105.

In various embodiments, the sliding sleeve 103 and the chamber body 101 each have one or more apertures. For example, in some embodiments, the sliding sleeve 103 is configured with a circular second air hole 1031 that is configured with a slotted first air hole 1011. Typically, each of these components has two or more apertures, but in some embodiments they may each have only one aperture. If in the closed position, the second air hole 1031 of the sliding sleeve 103 slides toward the rear of the novel valve body 100 (toward the end of the end cover 107), and does not overlap with the first air hole 1011 of the chamber body 101. Align. Since the second air hole 1031 of the sliding sleeve 103 is not aligned with the second air hole 1011 of the chamber tube body 101, the present manual quick release pressure valve 100 is closed to thereby hold the pressurized gas in the tank. In order to open the manual internal sliding valve body 100, the sliding sleeve 103 must be moved forward toward the front of the valve body 100 (opposite the end cover 107) until the second air hole 1031 of the sliding sleeve 103 and the chamber body The first air holes 1011 of the 101 are aligned, and the pressurized gas in the pressurized tank A passes through the first air holes 1011 and passes through the second air holes 1031, and flows out from the manual quick release valve 100. Typically, in the open position, the second air vent 1031 of the sliding sleeve 103 is aligned with the first air vent 1011 of the chamber body 101. However, in some embodiments, the holes are only partially aligned and overlap. In this case, if the holes are partially aligned, the holes are considered to be aligned so that air can pass from the pressurized can A to the outside of the pressurized can A through the novel valve body 100.

2A-A reveal a side view of the present manual quick release valve 100, revealing the four components of Fig. 1. The arrows shown in Figures 2A-A indicate the back of the end cap 107 from the valve body 100 of the present invention. The direction of the air flowing to the front. The manual quick release valve 100 is partially located inside the pressurized tank A and partially located outside the pressurized tank A. Typically, the external thread 1015, which is shown just behind the "L" shaped hole of the chamber body 101, matches the internal thread of the opening A1 of the pressurized can A such that everything behind the external thread 1015 is in the pressurized canister A. Inside. Further, the pressurized can A may be a pressurized can A as disclosed in FIG. Further, the first air hole 1011 of the chamber body 101 is always exposed to pressurization inside the pressurized tank A. However, the novel valve body 100 is opened only when the second air hole 1031 of the sliding sleeve 103 is aligned or partially aligned with the first air hole 1011 of the chamber tube body 101. When the second air hole 1031 of the sliding sleeve 103 is not aligned with the first air hole 1011 of the chamber tube body 101, the novel valve body 100 is closed. That is, when the second air hole 1031 of the sliding sleeve 103 slides to the right, away from the first air hole 1011 of the chamber tube body 101, the novel valve body 100 can prevent the pressure in the pressurized tank A. The air escapes through the second air hole 1031 of the sliding sleeve 103.

In particular, in another embodiment of the sliding sleeve 103, as shown in FIG. 2A-B, the sliding sleeve 103 is not provided with any second air hole 1031, and the above-mentioned new manual quick relief valve 100 can also be achieved. The function of opening and closing. For example, if the sliding sleeve 103 is operated to retreat, the outer wall of the chamber tube 101 closes the first air hole 1011 of the chamber tube body 101, thereby achieving the function of closing the pressure relief passage; if the sliding sleeve 103 is operated forward, The bottom hole of the sliding sleeve 103 is located in front of the first air hole 1011 of the chamber tube body 101, and the bottom hole is connected to the first air hole 1011 of the chamber tube body 101, thereby realizing the function of opening the pressure release passage.

The second air holes 1031 of the sliding sleeve 103 may be circular, for the sake of brevity of the present disclosure, and are distinguished from the first air holes 1011 of the chamber body 101. However, in practice, the second air holes 1031 of the sliding sleeve 103 may be of various shapes and sizes. Similarly, for the sake of brevity of the present disclosure, the first air holes 1011 of the chamber body 101 are referred to herein as slots and distinguish them from the second air holes 1031 of the sliding sleeve 103. . However, actually, that The chamber body 101 can be of various shape sizes. For example, the sliding sleeve 103 and/or the second air hole 1031 of the chamber body 101 may be circular, square, triangular, rectangular (grooved), pentagonal, hexagonal, with a circle. Angles, having squares, triangles or other sharp angles, symmetrical shapes, or other similar shapes known to those of ordinary skill in the art. The corresponding gas-air hole 1011 and the second air hole 1031 of the sliding sleeve 103 and the chamber body 101 may have the same or similar shapes, or may have different shapes. The sliding sleeve 103 and the chamber tube body 101 have corresponding gas-air holes 1011 and second air holes 1031 which may have the same area or may have different areas. Further, the sliding sleeve 103 and the chamber tube body 101 may have an air vent 1011, and the second air hole 1031 may have an edge which is inclined (or concave) or inclined (or convex) inward, and may have a straight Edges, or can have any combination of these.

The first air hole 1031 of the sliding sleeve 103 can generally be chamfered and/or have smoothed and rounded edges. This allows the first air hole 1031 of the sliding sleeve 103 to slide over the second O-ring 1014 in the chamber body 101 without disengaging the second O-ring 1014. Again, the second O-ring 1014 can be seen in the cross-sectional view of FIG. In some embodiments, the second O-ring 1014 can be positioned on the sliding sleeve 103 instead of the chamber tube 101. In such an embodiment, the first air hole 1011 of the chamber body 101 It may be chamfered and/or have smoothed and rounded edges to allow the second O-ring 1041 to slide over them without damaging or damaging the second O-ring 1041.

Figure 2B discloses a side view similar to that of Figures 2A-A. An operating lever 109 allows the user to manually open the new sliding inner slide valve 100. Therefore, the present invention is a "manual" internal spool valve that slides the operating lever 109 through a 100 axis around the novel valve body and then pushes it forward. To open the valve. The spring 105 assists in opening the valve. That is, the compression spring 105 tends to push the sliding sleeve 103 in a direction toward the valve opening (toward the front side away from the end cap 107). When the operating lever 109 is pushed forward, the sliding sleeve 103 that moves forward until its circular second air hole 1031 starts to slot with the chamber body 101 The first air hole 1011 is aligned. When the circular first air hole 1011 of the sliding sleeve 103 starts to start to rush through the slotted air of the chamber body 101, the volume of the second air hole 1031 is rapidly increased until each of the first air holes 1011 and 2 The vents 1031 are completely aligned and open the valve body 100 of the present invention.

Figure 3 discloses a perspective assembled side view of the discrete components of the manual internal slide valve 100 of Figure 2B. As shown in FIG. 3, the operating lever 109 passes through the "T" shaped entry aperture 1012a in the chamber body 101 instead of the "L" shaped access aperture 1012. In some cases, a "T" shaped entry aperture 1012a may allow the lever 109 to be more easily manipulated by a left-handed person. In various embodiments, the access aperture 1012 through which the operating lever 109 extends may have other shapes than the "I" or "T" shape. For example, the access aperture 1012 can be shaped to resemble a "J" (or double "J") such that the user must pull the lever 109 back slightly back before moving the lever 109 up and moving forward. This helps prevent accidental release of the valve body 100 when its device is picked up or gripped.

FIG. 4 discloses a perspective view of the manual quick release valve 100 with the end cap 107 removed. In this embodiment, the end cap 107 is provided with internal threads 1071 to aid in removal. In some embodiments, the first O-shaped 1013 ring is placed within the end cap 107 to help seal the valve body 100 when the novel valve body 100 is in the closed position. In FIG. 4, the first O-ring 1013 can be positioned at the end of the chamber tube 101. In other embodiments, the end cap 107 can be permanently affixed to one end of the chamber tube 101 by welding, gluing, bolting, or another similar, type of permanent fixation.

Figure 5 discloses a cross-sectional view of the closed state of the manual quick release valve 100 and the chamber body 101, while revealing a first O-ring 1013 and two second O-rings 1014. Figure 6 discloses a cross-sectional view of the chamber tube body 101, the combination of the sliding sleeve 103 and the end cap 107 in an open state. A first O-ring 1013 can be seen at the end of the chamber body 101, which helps to seal the novel valve to prevent leakage of pressurized air through the sliding sleeve 103. Usually, the aforementioned O-rings are made of flexible synthetic materials. Made of rubber or rubber. However, some embodiments use other types of seal rings, such as metal rings found in combustion engines or leather rings found in air pumps.
