[0002] In working environments with toxic and harmful gases, such as emergency response and harmful gas detection, especially in high-risk operations such as fire rescue, the life and health of workers are of vital importance. In these environments, workers must carry breathing oxygen supply devices to ensure breathing safety.

[0003] Traditional breathing oxygen supply devices control the supply of oxygen through an air supply regulating valve. However, during use, the oxygen in the breathing oxygen supply device is prone to gas loss due to leakage, which not only reduces the oxygen supply efficiency, but also cannot be adaptively adjusted on demand during the oxygen supply process.

[0074] A method for using an energy-saving gas supply regulating valve comprises the following steps:

[0075] Step A, closing the breathing hole 101 (oxygen supply from gas cylinder);

[0076] Step A1, press the valve button 401, the valve button 401 moves downward in the transmission cylinder 402 through the connecting cylinder 4011, and squeezes the first return spring 406, and the first return spring 406 contracts under the force until the inner teeth 4013 on the inner wall of the valve button 401 are engaged with the meshing teeth 4021 at the top of the transmission cylinder 402, so that the valve button 401 and the transmission cylinder 402 are engaged and connected;

[0077] Step A2, rotating the valve knob 401, the transmission cylinder 402 is driven to rotate through the engagement between the inner teeth 4013 and the meshing teeth 4021, the wedge-shaped arc teeth 4022 on the inner wall of the transmission cylinder 402 rotate on the outer wall of the follower cylinder 403 and fit into the wedge-shaped arc plate 4032, the bottom of the wedge-shaped arc teeth 4022 rotates along the inclined surface of the wedge-shaped arc plate 4032, and the wedge-shaped arc plate 4032 is abutted downward, driving the transmission cylinder 402 to move downward, until the bottom of the wedge-shaped arc teeth 4022 rotates to the arc-shaped groove 4033 at the top of the wedge-shaped arc plate 4032 and engages, and the transmission cylinder 402 moves downward to the bottom;

[0078] During the rotation of the transmission cylinder 402, the two groups of guide columns 4024 at the bottom rotate in the guide arc groove 2031 of the limit rotating plate 203, and the connected transmission gear 4023 rotates at the same time, and the transmission gear 4023 drives the driven gear 501 to rotate, so that the driven gear 501 connected to the switch mark 502 gradually rotates to the window 204 of the valve cover 2, and the opening and closing state of the breathing hole 101 is displayed through the window 204;

[0079] Step A3: The transmission cylinder 402 presses the second return spring 407 downward, the second return spring 407 is compressed, and the transmission cylinder 402 moves downward to fit the bottom end of the placement cylinder 201;

[0080] Step A4, the driving cylinder 402 moves downward and loses the acting force between the limiting cap 4041 of the connecting rod 404, the third return spring 408 is weakened and elastically elongated, and the elastic force is applied to the blocking disk 405, and the blocking disk 405 is forced to fit to the breathing diaphragm 3 of the breathing hole 101, and the acting force of the third return spring 408 is applied to the breathing diaphragm 3, so that the breathing diaphragm 3 blocks the breathing hole 101;

[0081] Step B, opening of the breathing hole 101 (other types of oxygen supply, such as a gas filter canister, etc.);

[0082] Step B1, press the valve button 401, the valve button 401 moves downward in the transmission cylinder 402 through the connecting cylinder 4011, and squeezes the first return spring 406, and the first return spring 406 contracts under the force until the inner teeth 4013 on the inner wall of the valve button 401 are engaged with the meshing teeth 4021 at the top of the transmission cylinder 402, so that the valve button 401 and the transmission cylinder 402 are engaged and connected;

[0085] During the reverse rotation of the transmission cylinder 402, the connected transmission gear 4023 rotates reversely, and the transmission gear 4023 drives the driven gear 501 to rotate reversely, so that the driven gear 501 connected to the switch mark 502 rotates out of the window 204 of the valve cover 2. At this time, the window 204 shows that the state of the breathing hole 101 is open.

[0086] The energy-saving gas supply regulating valve and the use method thereof of the present invention have the following advantages:

[0087] The present invention can flexibly control the opening and closing of the breathing hole 101 through the valve button 401 by setting the adjustment component 4. When the gas cylinder is needed to supply oxygen, the breathing hole 101 can be closed to improve the oxygen utilization rate in the oxygen cylinder, achieve energy-saving effects, effectively reduce the leakage of oxygen during the oxygen supply process, and improve the efficiency of oxygen use.

[0088] When other types of oxygen supply are used, the breathing hole 101 can be opened and oxygen can be supplied through the breathing hole 101 using other types of oxygen supply methods. The oxygen supply demand can be flexibly switched to adapt to the oxygen supply demand in different working environments (switching between cylinder oxygen supply or other types of oxygen supply), thereby improving the versatility and applicability of the air supply regulating valve.

[0089] The improved air supply regulating valve design can more effectively control the oxygen supply, ensure stable and sufficient oxygen when needed, reduce oxygen leakage and improve oxygen utilization efficiency, enhance the safety of workers in toxic and harmful gas environments, and reduce the risk caused by insufficient oxygen supply. At the same time, the status display component 5 is set up so that workers can intuitively understand the opening and closing status of the breathing hole 101, thereby better controlling the oxygen supply and ensuring rapid response in emergency situations.

[0090] The design of the valve button 401 allows the staff to control the opening and closing of the breathing hole 101 by simple pressing and turning operations. At the same time, the first return spring 406 arranged at the valve button 401 can separate the valve button 401 from the transmission cylinder 402 to prevent the staff from accidentally operating the rotating valve button 401, thereby isolating the possibility of misoperation, simplifying the operating process, and improving the convenience of use.

[0091] The control valve has a compact design and precise matching between various components, which reduces space occupation and is easy to integrate into various breathing oxygen supply devices. Due to the reasonable structural design, each component is easy to disassemble and replace, which is convenient for maintenance and servicing, reducing long-term operating costs.

[0092] The regulating valve is suitable for a variety of breathing oxygen supply devices and has a wide range of applicability, which can meet the needs of different working environments and conditions. By reducing oxygen leakage, the regulating valve helps to save oxygen resources, reduce energy waste, and has a significant energy-saving effect.

[0093] In emergency situations such as firefighting and rescue, the regulating valve can ensure that rescuers have a stable and sufficient supply of oxygen, thereby improving rescue efficiency and success rate.

[0094] By connecting with external control equipment, adaptive control of the gas supply regulating valve can be achieved, thereby improving the automation level of control.

[0095] While the invention has been shown and described, it will be appreciated by those skilled in the art that many changes, modifications, substitutions and variations may be made thereto without departing from the principles and spirit of the invention, the scope of the invention being defined by the appended claims and their equivalents.
