[0017] The present invention can be explained in detail through the following embodiments. The purpose of disclosing the present invention is to protect all technical improvements within the scope of the present invention. In the description of the present invention, it should be understood that if there are terms such as "upper", "lower", "front", "rear", "left", "right" indicating the orientation or positional relationship, they are only corresponding to the drawings of this application for the convenience of describing the present invention, and are not intended to indicate or imply that the device or element referred to must have a specific orientation.

[0018] Please refer to Figures 1-7. The present invention provides the following technical solutions: Embodiment 1: An integrated pneumatic dispensing device includes a gas cylinder 1, a valve body 2, and a main valve 5, a sealing joint 6, an actuating piston 8, and a secondary valve 9 installed in the valve body 2; one end of the valve body 2 is connected to the gas cylinder 1, and the high-pressure gas in the gas cylinder 1 enters the main valve 5 and the sealing joint 6 through the air inlet channel 2.2 in the valve body 2. Under the action of the pressure difference on both sides of the main valve 5, the main valve 5 abuts against the sealing joint 6 and seals; the valve body 2 is also provided with a pressure reducing channel 2.1 connected to the main valve 5, and the valve body 2 is provided with a secondary valve 9 for opening and closing the pressure reducing channel 2.1. When the actuating piston 8 is actuated, the secondary valve 9 opens the pressure reducing channel 2.1, and the high-pressure gas on the main valve 5 side is released through the pressure reducing channel 2.1. At this time, the main valve 5 moves under the action of the pressure difference and seals the gas. When the sealing connector 6 is separated, the high-pressure gas in the gas cylinder 1 is released into the system actuator through the outlet channel 2.3 and the outlet port. As shown in Figures 2 and 3, the valve body 2 is provided with an installation groove, and the main valve 5 and the sealing connector 6 are both located in the installation groove. The sealing connector 6 is threadedly connected to the installation groove and presses the main valve 5 into the installation groove. The main valve 5 includes a sealing seat 5.1, which is adapted to the installation groove. The outer wall of the sealing seat 5.1 is provided with a sealing ring. The end face of the sealing seat 5.1 is provided with a sealing pair 5.2 that cooperates with the sealing connector 6. The center of the sealing seat 5.1 has a channel, and a spring that abuts against the bottom of the installation groove is provided inside the sealing seat 5. The sealing connector 6 has an opening at one end facing the main valve 5, and the sealing connector 6 is provided radially with a vent hole 6 that connects the inlet channel 2.2 and the opening. 1. The outer wall of the sealing joint 6 is provided with two sealing rings, which are located on both sides of the vent hole 6.1. It can be understood that the high-pressure gas in the gas cylinder 1 enters the interior of the sealing joint 6 through the air inlet channel 2.2 and the vent hole 6.1 and acts on one end face of the sealing seat 5.1. At the same time, the high-pressure gas enters the sealing seat 5.1 through the channel in the center of the sealing seat 5.1 and acts on the other end face of the sealing seat 5.1. That is, the spring force in the sealing seat 5.1 and the air pressure on the left side of the sealing seat 5.1 are greater than the air pressure on the right side of the sealing seat 5.1. The main valve 5 abuts against the sealing joint 6 and seals. As shown in Figures 4 and 5, the valve body 2 is provided with a movable groove for the actuating piston 8 to move. The auxiliary valve 9 includes a valve seat 9.1, a valve stem 9.2 and a ball 9.3. The valve seat 9.1 and the valve... The valve body 2 is threaded and pressed to fix the sealing pair. One end of the valve seat 9.1 has an opening, and the valve seat 9.1 has a vent hole in the radial direction that connects to the opening. The valve seat 9.1 contains a spring and a valve stem 9.2. The valve body 2 has a through hole for the valve stem 9.2 to pass through, and the through hole extends to the movable groove. A ball 9.4 is fitted inside the through hole. Under the action of the spring, the valve stem 9.2 makes sealing contact with the sealing pair. At the same time, one end of the valve stem 9.2 presses and fixes the ball 9.4 to the end of the through hole, and the ball 9.4 partially extends into the movable groove. The end of the actuating piston 8 has a wedge-shaped surface that contacts the ball 9.4. It can be understood that an external force causes the actuating piston 8 to move downward. As the actuating piston 8 moves downward, the wedge-shaped surface of the actuating piston 8 contacts the ball 9.4 and pushes the ball 9.4 into the through hole.4. Pushing valve stem 9.2 to overcome spring force and separate valve stem 9.2 from the sealing pair, the pressure reducing channel 2.1 is opened, and high-pressure gas is discharged from valve body 2 through the radial air hole, opening and pressure reducing channel 2.1 of valve seat 9.1. At this time, the gas pressure on the left side of main valve 5 drops sharply, and the gas pressure on the right side of sealing seat 5.1 is much greater than the spring force inside sealing seat 5.1 and the gas pressure on the left side of sealing seat 5.1. Sealing seat 5.1 moves to the left and separates from sealing joint 6, releasing the high-pressure gas at the rear end of main valve 5. Under the action of pressure difference, main valve 5 opens to allow high-pressure gas to pass through. Gas is supplied to the actuating cylinder to release the projectile. Furthermore, a threaded sleeve 8.1 is fitted externally to the actuating piston 8. The threaded sleeve 8.1 is threadedly connected to the movable groove and limits the stroke of the actuating piston 8, preventing it from dislodging from the groove. Additionally, the upper end of the actuating piston 8 and the valve body 2 form an actuating chamber. This chamber is connected to the air inlet channel 2.2 via a high-pressure channel in the valve body 2. The valve body 2 is equipped with a solenoid valve for opening and closing the high-pressure channel. By supplying power to the solenoid valve, high-pressure gas enters the actuating chamber through the high-pressure channel and pushes the actuating piston 8 to move.

[0019] Example 2: Unlike Example 1, the valve body 2 is further provided with a flow regulating component 3 for adjusting the flow rate at the outlet of the valve body 2. The flow regulating component 3 includes an adjusting rod 3.1 and a positioning ball 3.5. The adjusting rod 3.1 is clearance-fitted with the valve body 2. The rod body of the adjusting rod 3.1 is radially provided with a first-position through hole 3.2 and a second-position through hole 3.3 corresponding to the outlet, and the diameter of the second-position through hole 3.3 is larger than the diameter of the first-position through hole 3.2. The rod body of the adjusting rod 3.1 is also circumferentially provided with an annular groove 3.4. A spring is provided inside the valve body 2. The spring causes the positioning ball 3.5 to engage with the annular groove 3.4. By using the flow regulating component 3, two-position flow rate adjustment can be achieved to meet the needs of different outlet flow rates. The axial locking of the adjusting rod 3.1 is achieved by the positioning ball 3.5 and the spring.

[0020] Example 3: Unlike Example 1, the valve body 2 is also provided with a pressure relief channel 2.4 corresponding to and connected to the air inlet channel 2.2. The valve body 2 is provided with a manual release assembly 4 for opening and closing the pressure relief channel 2.4. The manual release assembly 4 includes a guide sleeve 4.1 and a valve core 4.2. The pressure relief channel 2.4 has a conical sealing surface corresponding to the valve core 4.2. The guide sleeve 4.1 is threaded to the valve body 2. The end of the guide sleeve 4.1 is rotatably connected to the valve core 4.2. The end of the guide sleeve 4.1 has an internal hexagonal groove. When the manual release assembly 4 is opened, the guide sleeve 4.1 is tightened with a hexagonal wrench. The guide sleeve 4.1 drives the valve core 4.2 to rotate and move axially, causing the valve core 4.2 to fail to seal with the conical sealing surface of the pressure relief channel 2.4, thereby releasing the high-pressure gas in the gas cylinder 1.

[0021] Example 4: Unlike Example 1, valve body 2 is also equipped with a one-way valve 7 for filling gas cylinder 1; valve body 2 is also equipped with a temperature and pressure sensor for real-time monitoring of the temperature and pressure inside gas cylinder 1; valve body 2 is also equipped with a safety valve corresponding to the air inlet channel 2.2; high-pressure gas is filled into gas cylinder 1 through the one-way valve 7, and the temperature and pressure sensor can monitor the pressure and temperature inside the gas cylinder in real time and feed it back to the system. When the pressure inside gas cylinder 1 exceeds a certain value, the safety valve automatically opens and automatically depressurizes gas cylinder 1 to ensure the safety of personnel and equipment.

It will be apparent to those skilled in the art that this invention is not limited to the details of the above exemplary embodiments, and that the invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention.
