Description

Technical Field

[0001] This invention relates to a pneumatic control regulating valve and its usage method. Background Technology

[0002] In working environments with toxic or hazardous gases, such as emergency response, hazardous gas detection, and especially fire rescue, workers often need to carry gas cylinders and other gas delivery devices to supply oxygen and ventilation. These operations are crucial for ensuring the safety of workers.

[0003] Existing oxygen supply and ventilation control systems require operators to individually control each gas path in multiple gas supply devices, including gas cylinders and other gas delivery equipment. This cumbersome operation increases the workload for operators. Furthermore, the complexity of the operation may lead to operational errors by operators in complex working environments, increasing safety risks.

[0004] Therefore, a pneumatic control regulating valve and its usage method are proposed. Summary of the Invention

[0015] Preferably, the gas path control assembly includes a cover plate located on the regulating valve seat, a control valve button is provided on the cover plate, an adjusting rod is connected to the lower part of the control valve button through a drive disc, the adjusting rod extends through the drive disc to the inside of the cover plate and is connected to a closed disc, and the bottom end face of the closed disc is connected to the gas outlet.

[0016] The outer periphery of the closed disc is connected to a composite diaphragm, and the outer periphery of the composite diaphragm is connected to the inner liner valve cylinder, which is connected to the inner wall of the cover plate.

[0017] The drive disk has a through hole in the middle for the adjustment rod to pass through. The upper two sides of the adjustment rod are provided with limiting protrusions, and the outer diameter of the limiting protrusions is larger than the inner diameter of the through hole, so that the drive disk restricts the adjustment rod from moving downward through the limiting protrusions.

[0018] Preferably, a sealing spring is provided on the outer periphery of the adjusting rod, and the sealing spring is located between the cover plate and the closing disc, so that the closing disc abuts against the air outlet through the sealing spring;

[0019] A reset spring is provided between the lower part of the drive disk and the cover plate so that the drive disk can be reset by the reset spring.

[0020] Preferably, the inner wall of the control valve button is provided with three sets of wedge-shaped guide plates, the bottom end of the wedge-shaped guide plates is provided with an arc-shaped groove, the outer periphery of the drive disc is provided with three sets of connecting posts that cooperate with the arc-shaped groove, and the connecting posts are provided with guide blocks. The wedge-shaped guide plates and the guide blocks cooperate with each other to make the wedge-shaped guide plates move in connection with the guide blocks.

[0021] Preferably, a support cylinder is provided on the cover plate, and the inner wall of the support cylinder is provided with three sets of vertical grooves that cooperate with the connecting column, so that the drive disc can move linearly inside the support cylinder through the vertical grooves.

[0022] Preferably, the regulating valve seat has delivery ports on both sides for discharging gas from the gas delivery pipe, and a one-way diaphragm is provided at the delivery port.

[0023] Preferably, a control magnet is connected to the control valve button via a fixing plate below it, a Hall switch is provided on the regulating valve seat, and a Hall element is provided below the Hall switch, so that the control valve button controls the Hall switch to open and close via the control magnet.

[0024] The Hall switches are connected to the gas output devices corresponding to the gas delivery pipe and the gas cylinder delivery pipe, respectively.

[0025] A method for using a pneumatic control regulating valve includes the following steps:

[0026] Step A: Adjust the air output of the delivery air pipe;

[0027] Step A1: Press the control valve button to move the wedge guide plate down and fit it against the inclined surface of the guide block on the drive disc connecting column side;

[0028] Step A2: Rotate the control valve knob to make the wedge guide plate press the guide block downward through the inclined surface until the arc-shaped groove at the bottom of the wedge guide plate engages with the side of the connecting column.

[0029] Step A3: The drive disc moves down along the vertical groove on the inner wall of the cover plate support cylinder through the connecting column and squeezes the return spring. The return spring is compressed by force. At this time, the sealing spring elastically elongates and presses the closed disc against the air outlet of the inner liner cylinder to block the air outlet.

[0030] Step A4: The control valve button connecting fixing plate drives the control magnet to rotate, and the control magnet interacts with the Hall element to open the corresponding gas output device of the delivery gas pipe through the Hall switch, so as to realize the gas output of the delivery gas pipe.

[0031] Step B: Adjust the gas output of the gas cylinder delivery pipe;

[0032] Step B1: Rotate the control valve knob in the reverse direction to move the wedge-shaped guide plate out from the upper end of the connecting column through the arc-shaped groove. The return spring elastically extends, and the drive disc moves upward inside the support cylinder through the vertical groove.

[0033] Step B2: The through hole of the drive disc moves upward through the limiting protrusion to connect the adjusting rod, which drives the closed disc at the bottom of the adjusting rod to move out from the air outlet of the inner liner. At the same time, the connecting diaphragm bulges, thereby releasing the blocking effect on the air outlet.

[0034] Step B3: The control valve button connecting fixing plate drives the control magnet to rotate in the opposite direction, and the control magnet contacts the Hall element. The Hall switch controls the gas cylinder output, and the gas in the gas cylinder is output to the connecting bushing side through the gas cylinder delivery pipe.

[0035] Step B4: The gas pressure output from the gas cylinder acts on the venting cylinder, causing the venting cylinder to move towards the outlet cylinder, squeezing the gas pressure regulating spring located inside the outlet cylinder until a gap is created between the venting cylinder and the connecting bushing. The gas output from the gas cylinder's gas delivery pipe is then output to the outlet of the inner liner cylinder and output to the inner liner valve cylinder through the outlet.

[0036] Step B5: The air pressure inside the inner liner valve cylinder increases, squeezing the one-way diaphragm to fit the conveying port position and sealing the conveying port;

[0037] Step B6: The gas output from the gas cylinder supply pipe is output to the supply port through the inner liner valve cylinder, and then output to the component connected to the connecting shaft cylinder through the supply port, thus completing the gas cylinder gas output.

[0038] Step C: Adjust the gas cylinder output pressure;

[0039] Step C1: Rotate the threaded adjusting pin on the adjusting bolt side to control the adjusting bolt to move towards the inside of the air outlet at the threaded opening of the air outlet. The moving adjusting bolt compresses the air pressure adjusting spring, increasing the contact force between the air outlet and the connecting bushing, thereby increasing the pressure required for the gas cylinder output and reducing the gas output pressure in the regulating gas cylinder.

[0040] Step C2: Rotate the threaded adjusting pin on the side of the adjusting bolt in the opposite direction to control the adjusting bolt to move outward from the threaded opening of the air outlet. The air pressure adjusting spring will stretch relatively, reducing the contact force between the air outlet and the connecting bushing, thereby reducing the pressure required for the gas cylinder to output and increasing the gas output pressure in the regulating cylinder.

[0041] Compared with the prior art, the beneficial effects of the present invention are:

[0042] This invention achieves centralized control of the gas delivery pipe and gas cylinder delivery pipe through an integrated gas path control regulating valve, reducing the number of parts that operators need to operate and thus simplifying the operation process.

[0043] Centralized control reduces the number of steps staff need to take in emergency situations, improving response speed and operational efficiency, especially in time-sensitive emergency response and fire rescue scenarios. Reducing the number of steps also lowers the risk of operational errors.

[0044] The pressure regulating component and the gas path control component enable precise adjustment of the gas cylinder output pressure. At the same time, the gas path can be quickly adjusted, and the gas cylinder output gas path can be effectively isolated from the delivery gas pipe to avoid mixing between the gas cylinder output gas and the gas delivery pipe output gas, ensuring the purity of the gas cylinder output gas and guaranteeing the stability and reliability of oxygen supply and air delivery.

[0045] This gas control regulating valve is suitable for various working environments with toxic and harmful gases, improving its adaptability and versatility. Attached Figure Description

Detailed Implementation

[0059] To address the issue that existing oxygen supply and ventilation control devices require operators to individually control each gas path in multiple gas path devices such as gas cylinders and other gas delivery devices, resulting in cumbersome operation and increased workload for operators; furthermore, complex operations may lead to operational errors in complex working environments, increasing safety risks, this invention provides a gas path control regulating valve and its usage method. The technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0060] Please see Figure 1-12 The present invention provides a pneumatic control regulating valve, comprising a pneumatic delivery pipe 1 and a regulating valve seat 2.

[0061] The gas delivery pipe 1 is equipped with a gas cylinder delivery pipe 3 inside. The output ends of the gas delivery pipe 1 and the gas cylinder delivery pipe 3 are connected to the input end of the regulating valve seat 2. A gas delivery port 4 is provided at the bottom end of the regulating valve seat 2. A connecting shaft cylinder 5 is provided at the gas delivery port 4.

[0062] The regulating valve seat 2 is equipped with a pressure regulating component 6 at the output end of the gas cylinder supply pipe 3. The upper part of the pressure regulating component 6 is provided with an inner liner 7, and an air outlet 701 is opened at the upper part of the inner liner 7. A gas path control component 8 is provided directly above the air outlet 701.

[0063] The regulating valve seat 2 regulates the opening and closing of the gas delivery pipe 1 and the gas cylinder delivery pipe 3 through the gas path control component 8.

[0064] The pressure regulating assembly 6 further includes a guide shaft cylinder 601 disposed at the regulating valve seat 2. The input end of the guide shaft cylinder 601 is connected to the output end of the gas cylinder supply pipe 3. A connecting sleeve 602 is connected to the side of the guide shaft cylinder 601 away from the gas cylinder supply pipe 3. A vent cylinder 603 is connected to one side of the connecting sleeve 602. An outlet cylinder 604 is fitted on the side of the vent cylinder 603 away from the connecting sleeve 602. A threaded opening 605 is provided on the side of the outlet cylinder 604 away from the vent cylinder 603, and the outlet cylinder 604 is located in the inner liner cylinder 7. The gas cylinder supply pipe 3 pumps gas from the gas cylinder into the connecting sleeve 602 through the guide shaft cylinder 601.

[0065] The inner diameter of the connecting sleeve 602 is larger than the inner diameter of the ventilator 603, so that the air output of the connecting sleeve 602 is greater than the air intake of the ventilator 603. The ventilator 603 is moved by controlling the air pressure. The gas cylinder gas is pressed by the air pressure to bring the ventilator 603 against the inside of the outlet cylinder 604, thereby controlling the gap between the connecting sleeve 602 and the ventilator 603, and the gas cylinder gas is discharged through the gap.

[0066] Furthermore, a pressure regulating spring 606 is provided inside the air outlet 604. An adjusting bolt 607 is provided on the side of the pressure regulating spring 606 away from the air outlet 604. A threaded adjusting post 608 that mates with the threaded opening 605 is provided on the side of the adjusting bolt 607 away from the pressure regulating spring 606. Through the provided pressure regulating spring 606, the air outlet 603 is pressed against the pressure regulating spring 606. By rotating the adjusting bolt 607, the pressure regulating spring 606 is pressed, thus adjusting the elastic force of the pressure regulating spring 606, thereby adjusting the pressure between the air outlet 603 and the pressure regulating spring 606, and adjusting the air pressure when the gas from the gas cylinder is pumped out.

[0067] The outer periphery of the vent 603, the adjusting plug 607, and the air outlet 604 are all provided with sealing rings.

[0068] The further gas path control component 8 includes a cover plate 801 located on the regulating valve seat 2. A control valve button 802 is provided on the cover plate 801. The lower part of the control valve button 802 is connected to an adjusting rod 804 through a drive disc 803. The adjusting rod 804 extends through the drive disc 803 into the interior of the cover plate 801 and is connected to a closing disc 805. The bottom end face of the closing disc 805 is connected to the air outlet 701.

[0069] The outer periphery of the closed disc 805 is connected to a composite diaphragm 806, and the outer periphery of the composite diaphragm 806 is connected to an inner liner valve cylinder 807, which is connected to the inner wall of the cover plate 801. The drive disc 803 can drive the composite diaphragm 806 to move out / fit from the air outlet 701 and control the opening / closing of the air outlet 701.

[0070] Furthermore, the drive disk 803 has a through hole 8033 in the middle for the adjustment rod 804 to pass through. The upper two sides of the adjustment rod 804 are provided with limiting protrusions 8041, and the outer diameter of the limiting protrusions 8041 is larger than the inner diameter of the through hole 8033, so that the drive disk 803 restricts the adjustment rod 804 from moving downward through the limiting protrusions 8041.

[0071] Furthermore, a sealing spring 808 is provided on the outer periphery of the adjusting rod 804, and the sealing spring 808 is located between the cover plate 801 and the closing disc 805, so that the closing disc 805 abuts against the air outlet 701 through the sealing spring 808.

[0072] A reset spring 809 is provided between the lower part of the drive disc 803 and the cover plate 801 so that the drive disc 803 can be reset by the reset spring 809. When the control valve button 802 rotates in the opposite direction, the force between the control valve button 802 and the drive disc 803 decreases, and the reset spring 809 elastically elongates, lifting the drive disc 803 to reset.

[0073] Furthermore, the inner wall of the control valve button 802 is provided with three sets of wedge-shaped guide plates 8021. The bottom end of each wedge-shaped guide plate 8021 has an arc-shaped groove 8022. The outer periphery of the drive disc 803 is provided with three sets of connecting posts 8031 ​​that mate with the arc-shaped grooves 8022. Guide blocks 8032 are provided on the sides of each connecting post 8031. The wedge-shaped guide plates 8021 and guide blocks 8032 cooperate with each other to allow the wedge-shaped guide plates 8021 to move along with the guide blocks 8032. The arc-shaped inclined surface of the wedge-shaped guide plate 8021 mates with the inclined surface of the guide block 8032. During rotation, the wedge-shaped guide plate 8021 can be pressed and adhered to the inclined surface of the guide block 8032 through the arc-shaped inclined surface, controlling the downward movement of the guide block 8032.

[0074] A support cylinder 9 is provided on the cover plate 801. The inner wall of the support cylinder 9 has three sets of vertical grooves 901 that cooperate with the connecting column 8031, so that the drive disk 803 can move linearly inside the support cylinder 9 through the vertical grooves 901. The vertical grooves 901 can prevent the drive disk 803 from deflecting on the inner wall of the support cylinder 9, and ensure that the drive disk 803 moves up and down.

[0075] Furthermore, the regulating valve seat 2 has delivery ports 10 on both sides for discharging gas from the gas delivery pipe 1. A one-way diaphragm 11 is provided at the delivery port 10. When the gas cylinder outputs gas through the gas cylinder output pipe, the internal pressure of the inner liner valve cylinder 807 increases, causing the one-way diaphragm 11 to adhere to the delivery port 10, thus blocking the gas output path of the gas delivery pipe 1. This prevents outside air from being pumped into the inner liner valve cylinder 807 through the delivery port 10 of the gas delivery pipe 1, ensuring the purity of the gas output from the gas cylinder and preventing gas leakage from the gas cylinder.

[0076] Furthermore, a control magnet 13 is connected to the control valve button 802 via a fixing plate 12 below it, a Hall switch 15 is provided on the regulating valve seat 2, and a Hall element 14 is provided below the Hall switch 15, so that the control valve button 802 controls the Hall switch 15 to open and close via the control magnet 13.

[0077] The Hall switch 15 is connected to the gas output device corresponding to the gas delivery pipe 1 and the gas cylinder delivery pipe 3 respectively; the Hall switch 15 can be opened and closed when the control valve button 802 drives the control magnet 13 to rotate.

[0078] A method for using a pneumatic control regulating valve includes the following steps:

[0079] Step A: Adjust the air output of delivery pipe 1;

[0080] Step A1: Press the control valve button 802 to move the wedge guide plate 8021 down and fit it against the inclined surface of the guide block 8032 on the side of the drive disc 803 connecting column 8031;

[0081] Step A2: Rotate the control valve knob 802 to make the wedge guide plate 8021 press the guide block 8032 downward through the inclined surface until the arc groove 8022 at the bottom of the wedge guide plate 8021 is engaged with the side of the connecting column 8031.

[0082] Step A3: The drive disc 803 moves down along the vertical groove 901 on the inner wall of the cover plate 801 and the support cylinder 9 via the connecting column 8031, pressing the reset spring 809. The reset spring 809 is compressed by force. At this time, the sealing spring 808 elastically elongates, and the closing disc 805 abuts against the air outlet 701 of the inner liner cylinder 7, blocking the air outlet 701.

[0083] Step A3: The control valve button 802 connects to the fixing plate 12, which drives the control magnet 13 to rotate. The control magnet 13 interacts with the Hall element 14, and the Hall switch 15 opens the gas output device corresponding to the gas delivery pipe 1, so as to realize the gas output of the gas delivery pipe 1.

[0084] Step B: Adjust the gas output of gas cylinder delivery pipe 3;

[0085] Step B1: Rotate the control valve button 802 in the reverse direction to move the wedge-shaped guide plate 8021 out from the upper end of the connecting column 8031 ​​through the arc-shaped groove 8022. The return spring 809 elastically extends, and the drive disc 803 moves upward inside the support cylinder 9 through the vertical groove 901.

[0086] Step B2: The through hole 8033 of the drive disc 803 is connected to the adjusting rod 804 through the limiting protrusion 8041 and moves upward, causing the closed disc 805 at the bottom of the adjusting rod 804 to move out from the air outlet 701 of the inner liner 7. At the same time, the connecting composite diaphragm 806 bulges up, thereby releasing the blocking effect on the air outlet 701.

[0087] Step B3: The control valve button 802 connects to the fixing plate 12, which drives the control magnet 13 to rotate in the opposite direction. The control magnet 13 interacts with the Hall element 14, and controls the gas cylinder output through the Hall switch 15, so that the gas in the gas cylinder is output to the connecting bushing 602 side through the gas cylinder delivery pipe 3.

[0088] Step B4: The gas pressure output from the gas cylinder acts on the venting cylinder 603, causing the venting cylinder 603 to move towards the outlet cylinder 604, compressing the gas pressure regulating spring 606 located inside the outlet cylinder 604 until a gap is created between the venting cylinder 603 and the connecting bushing 602. The gas output from the gas cylinder supply pipe 3 is then output to the outlet 701 of the inner liner cylinder 7, and output to the inner liner valve cylinder 807 through the outlet 701.

[0089] Step B5: The internal air pressure of the inner liner valve cylinder 807 increases, squeezing and attaching the one-way diaphragm 11 to the position of the conveying port 10, thus sealing the conveying port 10.

[0090] Step B6: The gas output from the gas cylinder supply pipe 3 is output to the supply port 4 through the inner liner valve cylinder 807, and then output to the component connected to the connecting shaft cylinder 5 through the supply port 4, thus completing the gas cylinder gas output.

[0091] Step C: Adjust the gas cylinder output pressure;

[0092] Step C1: Rotate the threaded adjusting pin 608 on the side of the adjusting bolt 607 to control the adjusting bolt 607 to move inward at the threaded opening 605 of the air outlet 604. The moving adjusting bolt 607 compresses the air pressure adjusting spring 606, increasing the contact force between the air outlet 603 and the connecting bushing 602, thereby increasing the pressure required for the gas cylinder output and reducing the gas output pressure in the regulating gas cylinder.

[0093] Step C2: Rotate the threaded adjusting pin 608 on the side of the adjusting bolt 607 in the opposite direction to control the adjusting bolt 607 to move outward from the threaded opening 605 of the air outlet 604. The air pressure adjusting spring 606 will be relatively extended, reducing the contact force between the air outlet 603 and the connecting bushing 602, thereby reducing the pressure required for the gas cylinder output and increasing the gas output pressure in the regulating cylinder.

[0094] The pneumatic control regulating valve and its method of use of the present invention have the following advantages:

[0095] The integrated gas path control regulating valve enables centralized control of the gas delivery pipe 1 and the gas cylinder delivery pipe 3, reducing the number of parts that staff need to operate and thus simplifying the operation process.

[0096] Centralized control reduces the number of steps staff need to take in emergency situations, improving response speed and operational efficiency, especially in time-sensitive emergency response and fire rescue scenarios. Reducing the number of steps also lowers the risk of operational errors.

[0097] The pressure regulating component 6 and the gas path control component 8 enable precise adjustment of the gas cylinder output pressure. At the same time, the gas path can be quickly adjusted, and the gas cylinder output gas path can be effectively isolated from the delivery gas pipe 1 to avoid mixing between the gas cylinder output gas and the gas pipe 1 output gas, ensuring the purity of the gas cylinder output gas and guaranteeing the stability and reliability of oxygen supply and air delivery.

[0098] This gas control regulating valve is suitable for various working environments with toxic and harmful gases, improving its adaptability and versatility.

[0099] Although the invention has been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these inventions without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.

The upper two sides of the adjustment rod (804) are provided with limiting protrusions (8041), and the outer diameter of the limiting protrusions (8041) is larger than the inner diameter of the through hole (8033) so that the drive disk (803) restricts the adjustment rod (804) from moving downward through the limiting protrusions (8041).

5. A pneumatic control regulating valve according to claim 4, characterized in that: A sealing spring (808) is provided on the outer periphery of the adjusting rod (804), and the sealing spring (808) is located between the cover plate (801) and the closing plate (805) so that the closing plate (805) abuts against the air outlet (701) through the sealing spring (808); A reset spring (809) is provided between the lower part of the drive disk (803) and the cover plate (801) so that the drive disk (803) can be reset by the reset spring (809).

6. A method of using a pneumatic control regulating valve according to claim 5, characterized in that: Includes the following steps: Step A: Adjust the air output of the delivery air pipe (1); Step A1: Press the control valve button (802) to move the wedge guide plate (8021) down and fit against the inclined surface of the guide block (8032) on the side of the drive disc (803) connecting column (8031); Step A2: Rotate the control valve knob (802) to make the wedge guide plate (8021) press the guide block (8032) downward through the inclined surface until the arc groove (8022) at the bottom of the wedge guide plate (8021) is engaged with the side of the connecting column (8031); Step A3: The drive disc (803) moves down along the vertical groove (901) on the inner wall of the cover plate (801) and support cylinder (9) via the connecting column (8031) to squeeze the reset spring (809). The reset spring (809) is compressed by force. At this time, the sealing spring (808) elastically elongates and brings the closing disc (805) against the air outlet (701) of the inner liner cylinder (7) to block the air outlet (701). Step A3: The control valve button (802) connects to the fixing plate (12) to drive the control magnet (13) to rotate. The control magnet (13) contacts the Hall element (14). The Hall element (14) opens the corresponding air output device of the air delivery pipe (1) through the Hall switch (15) to realize the air output of the air delivery pipe (1). Step B: Adjust the gas cylinder supply pipe (3) gas output; Step B1: Rotate the control valve knob (802) in the reverse direction to move the wedge-shaped guide plate (8021) out from the upper end of the connecting column (8031) through the arc-shaped groove (8022). The return spring (809) elastically elongates, and the drive disc (803) moves upward inside the support cylinder (9) through the vertical groove (901). Step B2: The through hole (8033) of the drive disc (803) is connected to the adjusting rod (804) through the limiting protrusion (8041) and moves upward, causing the closed disc (805) at the bottom of the adjusting rod (804) to move out from the air outlet (701) of the inner liner (7), and at the same time the connecting composite diaphragm (806) bulges up, thereby releasing the blocking effect on the air outlet (701); Step B3: The control valve button (802) connects to the fixing plate (12) and drives the control magnet (13) to rotate in the opposite direction. The control magnet (13) interacts with the Hall element (14) and controls the gas cylinder output through the Hall switch (15). The gas in the gas cylinder is output to the connecting bushing (602) side through the gas cylinder delivery pipe (3). Step B4: The gas pressure output from the gas cylinder acts on the ventilation cylinder (603), and the ventilation cylinder (603) moves towards the outlet cylinder (604) under force, squeezing the gas pressure regulating spring (606) located inside the outlet cylinder (604) until a gap is created between the ventilation cylinder (603) and the connecting bushing (602). The gas output from the gas cylinder delivery pipe (3) is output to the outlet (701) of the inner liner cylinder (7), and output to the inner liner valve cylinder (807) through the outlet (701). Step B5: The internal air pressure of the inner liner valve cylinder (807) increases, which squeezes the one-way diaphragm (11) to the position of the conveying port (10) and seals the conveying port (10); Step B6: The gas output from the gas cylinder supply pipe (3) is output to the gas supply port (4) through the inner liner valve cylinder (807), and then output to the component connected to the connecting shaft cylinder (5) through the gas supply port (4), thus completing the gas cylinder gas circuit output. Step C: Adjust the gas cylinder output pressure; Step C1: Rotate the threaded adjusting pin (608) on the side of the adjusting pin (607) to control the adjusting pin (607) to move towards the inside of the air outlet (604) at the threaded opening (605) of the air outlet (604). The adjusting pin (607) moves and squeezes the air pressure adjusting spring (606), increasing the contact force between the air outlet (603) and the connecting bushing (602), thereby increasing the pressure required for the gas cylinder output and reducing the gas output pressure in the regulating gas cylinder. Step C2: Rotate the threaded adjusting pin (608) on the side of the adjusting bolt (607) in the opposite direction to control the adjusting bolt (607) to move outward at the threaded opening (605) of the air outlet (604). The air pressure adjusting spring (606) will be relatively extended, reducing the contact force between the air outlet (603) and the connecting bushing (602), thereby reducing the pressure required for the gas cylinder output and increasing the gas output pressure in the regulating gas cylinder.
