[0018] In order to further understand the features, technical means, specific objectives and functions achieved by the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0019] like Figures 1-8 The energy-saving air supply regulating valve shown in the figure includes a valve body 1, the valve body 1 adjusts the air supply through a first motor 2, the valve body 1 has an air inlet 3 and an air outlet 4 at both ends, one end of the valve body 1 is connected to an outer cavity 5, the air inlet 3 is connected to the outer cavity 5 through a first air inlet 6, the outer cavity 5 is connected to the inside of the valve body 1 through an air outlet 7, an adjusting cavity 8 is provided above the outer cavity 5, a rotating rod 9 is provided in the outer cavity 5, a micro generator 10 is provided on the top of the adjusting cavity 8, the top of the rotating rod 9 passes through the adjusting cavity 8 and is connected to the micro generator 10 Transmission connection, a lifting sleeve 11 is provided on the sliding sleeve of the rotating rod 9, and the lifting sleeve 11 is arranged in the adjusting cavity 8 and the outer cavity 5. A plurality of wind-blocking baffles 12 that can be deflected are provided in a ring on the rotating rod 9. The wind-blocking baffle 12 is located in the outer cavity 5. A pressure push ring 13 is connected to the top of the lifting sleeve 11. The lifting process of the lifting sleeve 11 drives the wind-blocking baffle 12 to deflect. The air inlet 3 is connected to the cavity between the top of the adjusting cavity 8 and the pressure push ring 13 through the second air inlet duct 14, and the micro generator 10 is electrically connected to the first motor 2.

[0020] The energy-saving air supply regulating valve is centered around valve body 1. A first motor 2 regulates the air supply, providing basic gas flow control. One end of valve body 1 is connected to outer chamber 5. The air inlet 3 communicates with outer chamber 5 via a first air inlet duct 6. The outer chamber 5, in turn, connects to the interior of valve body 1 via an air outlet duct 7, forming a gas flow path. High-pressure gas is introduced into outer chamber 5, providing the power source for subsequent functions.

[0021] The top end of the rotating rod 9 in the outer cavity 5 is in transmission connection with the micro generator 10 through the adjusting cavity 8, forming an energy conversion link. The top end of the lifting sleeve 11 slidingly sleeved on the rotating rod 9 is connected with the pressing ring 13, and the high-pressure gas can push the pressing ring 13 to drive the lifting sleeve 11 to rise and fall, and in the process of rising and falling, the air resistance baffle 12 on the rotating rod 9 is driven to deflect. The air inlet 3 is communicated with the cavity between the top of the adjusting cavity 8 and the pressing ring 13 through the second air inlet 14, and when the gas enters the cavity, it pushes the pressing ring 13 and the lifting sleeve 11 to move downward, and then drives the air resistance baffle 12 to deflect. The deflection of the air resistance baffle 12 changes the gas flow resistance in the outer cavity 5, and drives the rotating rod 9 to rotate, so that the micro generator 10 generates electricity, and the generated electricity supplies the first motor 2, and provides energy supply for the first motor 2 to realize gas regulation.

[0022] When the gas pressure is low, the gas can directly enter the outer cavity 5 through the first air inlet 6, and be smoothly introduced into the valve body 1 through the air outlet 7 and discharged, at this time, the air resistance baffle 12 is in the initial state, and there is no obvious hindrance to the gas flow, which ensures the normal transportation of the gas under low gas pressure. When the gas pressure is high, the high-pressure gas enters the adjusting cavity 8 through the second air inlet 14, and the high-pressure gas acts on the pressing ring 13, forcing it to move downward, and the pressing ring 13 drives the lifting sleeve 11 to move downward synchronously, and the lifting sleeve 11 drives the air resistance baffle 12 to deflect. The deflected air resistance baffle 12 forms a paddle-like structure in the outer cavity 5, which can withstand the impact force of the gas blown by the first air inlet 6, and effectively convert the pressure energy of the gas into the driving torque of the rotating rod 9. The rotating rod 9 drives the micro generator 10 to generate electricity, and the generated electricity not only supplies power to the first motor 2, but also stores the excess part in the matching battery, realizing the rational utilization and storage of energy. Through the design of gas pressure step adjustment, unnecessary energy loss is reduced under low gas pressure, and the gas pressure energy is efficiently recovered to convert into electric energy under high gas pressure, realizing the on-demand utilization of energy. Compared with the traditional gas regulating valve, the energy consumption is significantly reduced, realizing energy-saving operation, and the operation cost can be greatly reduced in long-term use.

[0023] The gas regulating valve has the ability of gas pressure self-adaptive regulation, and can stably and independently operate for a long time under low gas pressure or high gas pressure without frequent manual intervention. The gas regulating valve does not need external stable power supply, and realizes self-provided power by gas pressure driving. Under high gas pressure, not only the power demand of the first motor 2 can be met, but also the excess power can be stored in the battery, and when the gas pressure is insufficient or the power generation is low, the battery is used to supply power to maintain the system operation. In remote areas without power facilities, or places where power supply is unstable and prone to power failure, the system can rely on gas power to continuously and stably operate, ensuring the normal use of the gas regulating function.

[0024] It is worth mentioning that the magnetic rheological damper can be installed on the rotating shaft 9, and when the rotating speed exceeds the preset value, the damping increases nonlinearly with the flow rate, preventing overspeed.

[0025] It is worth mentioning that the second air inlet 14 is straight through with the air inlet 3, the first air inlet 6 is arranged at the bifurcation of the second air inlet 14, and the flow channel length of the second air inlet 14 is greater than that of the second air inlet 14. This way can ensure that the high-pressure gas first impacts and extrudes the pressure pushing ring 13 inside the adjusting cavity 8, ensuring that the pressure pushing ring 13 can be pushed out downward when the pressure is sufficient.

[0026] The outer cavity 5 is also provided with a plurality of deflection shafts 15 arranged annularly around the rotating shaft 9, the deflection shafts 15 are horizontally arranged and connected with the rotating shaft 9, the wind resistance baffle 12 is fixedly installed on the deflection shaft 15, and the lifting sleeve 11 is in transmission connection with the deflection shaft 15.

[0027] The wind resistance baffle 12 is fixedly installed on the deflection shaft 15, and the deflection shaft 15 is in transmission connection with the lifting sleeve 11. When the lifting sleeve 11 rises and falls under the action of high-pressure gas, the deflection shaft 15 is rotated through the lifting and falling transmission of the lifting sleeve 11, and then the synchronous deflection of the wind resistance baffle 12 is realized. This design ensures that multiple wind resistance baffles 12 can change angles in coordination to form a stable paddle structure.

[0028] The bottom of the lifting sleeve 11 is provided with a transmission rod 16, one end of the transmission rod 16 is hinged to the bottom of the lifting sleeve 11, the lifting sleeve 11 is further sleeved with a limiting sleeve 17, a vertical limiting groove 18 for installing the transmission rod 16 is vertically arranged on the limiting sleeve 17, the transmission rod 16 is in sliding cooperation with the limiting sleeve 17, the limiting sleeve 17 is fixedly connected with the rotating shaft 9, a spiral groove 19 is arranged on the deflection shaft 15, and one end of the transmission rod 16 away from the lifting sleeve 11 is arranged in the spiral groove 19.

[0029] When the lifting sleeve 11 moves up and down under the driving of the pressure pushing ring 13, the transmission rod 16 can swing, the lifting sleeve 11 is sleeved with the limiting sleeve 17 fixedly connected with the rotating shaft 9, and the vertically arranged limiting groove on the limiting sleeve 17 guides and restricts the transmission rod 16, avoiding deviation or shaking during movement. In the rotating process, the rotating shaft 9, the lifting sleeve 11, the limiting sleeve 17 and the transmission rod 16 rotate synchronously.

[0030] When the transmission rod 16 is deflected under the limiting groove, that is, the end of the transmission rod 16 is displaced horizontally outward to the side away from the rotating rod 9, the helical groove 19 converts the linear motion into the rotary motion of the deflection shaft 15, thereby driving the deflection of the wind baffle 12, realizing the precise control of the angle of the wind baffle 12. This mechanical transmission mode is more stable and reliable than electronic control, especially suitable for outdoor harsh environments, can long-term maintain the accuracy of angle adjustment, and ensures that the system can stably operate under different air pressure conditions. In a high air pressure environment, the structure can quickly respond and adjust the angle of the wind baffle 12, ensure the micro generator 10 to generate electricity efficiently, further strengthen the energy-saving characteristics of the air supply regulating valve, reduce the failure points, reduce the manufacturing and maintenance costs, and meet the requirements of reliability and easy maintenance of outdoor long-time unattended equipment.

[0031] An annular opening groove 20 is formed on the outer side wall of the rotating rod 9, which is located at the connecting position of the lifting sleeve 11. A first sealing ring 21 is arranged in the annular opening groove 20 to form a sliding sealing pair with the lifting sleeve 11. The lifting sleeve 11 and the top of the outer cavity 5 are connected by a second sealing ring 22 to form a sliding sealing pair.

[0032] An annular opening groove 20 is formed on the outer side wall of the rotating rod 9 at the connecting position of the lifting sleeve 11. A first sealing ring 21 is embedded in the groove to form a sliding sealing pair with the inner wall of the lifting sleeve 11. This structure not only allows the lifting sleeve 11 to freely slide along the axis of the rotating rod 9, but also effectively prevents the gas in the outer cavity 5 from leaking along the surface of the rotating rod 9. A second sealing ring 22 is arranged between the outer periphery of the lifting sleeve 11 and the top of the outer cavity 5 to form a sliding sealing interface. This design ensures the flexibility of the lifting sleeve 11 in up-down movement, prevents the gas in the outer cavity 5 from seeping into the adjusting cavity 8, and ensures the independence of the pressure in the two chambers. By arranging dynamic sealing structures on the contact surfaces of the rotating rod 9 and the lifting sleeve 11 and the contact surfaces of the lifting sleeve 11 and the top of the outer cavity 5, a double barrier is formed to ensure that the high-pressure gas flows along the predetermined path, avoiding energy loss and interference caused by gas mixing.

[0033] The double sealing reduces gas leakage, so that more high-pressure gas energy can be used to drive the wind baffle 12, improving the mechanical energy conversion efficiency and strengthening the energy-saving characteristics of the system. The sealing structure ensures that the pressure change in the adjusting cavity 8 accurately corresponds to the inlet air pressure, making the angle adjustment of the wind baffle 12 more sensitive and improving the self-adaptive ability of the system to different air pressure environments.

[0034] A limiting ring 23 is arranged on the inner wall of the adjusting cavity 8 to limit the upper limit position of the pressure pushing ring 13. A third sealing ring 24 is arranged on the outer side wall of the pressure pushing ring 13 to form a sliding sealing pair with the inner wall of the adjusting cavity 8. A balance hole 25 is formed in the lower part of the adjusting cavity 8 to communicate with the atmosphere.

[0035] The third sealing ring 24 on the outer periphery of the push ring 13 forms a sliding sealing pair with the inner wall of the adjusting cavity 8 to prevent high-pressure gas from leaking along the outer side of the push ring 13, thereby ensuring that the high-pressure gas can smoothly push the push ring 13 to move downward.

[0036] The bottom end of the push ring 13 is fixedly installed with a locking cylinder 26, and the adjusting cavity 8 is further provided with a support frame 27, a hinged shaft 28, a locking rod 29, and a locking pin 30. The support frame 27 is fixedly installed on the top of the outer cavity 5, the middle part of the locking rod 29 is hingedly connected to the support frame 27 through the hinged shaft 28, the locking pin 30 is slidingly arranged on the locking rod 29 along the axis of the locking rod 29, the locking rod 29 is hollow inside, and the locking rod 29 is provided with a locking spring inside. The two ends of the locking spring are fixedly connected with the locking rod 29 and the locking pin 30, respectively. The inner wall of the locking cylinder 26 is provided with a plurality of locking ring grooves 32 in the vertical direction, and the locking pin 30 cooperates with the locking ring grooves 32.

[0037] When the push ring 13 descends, the locking pin 30 is embedded in the corresponding height of the locking ring groove 32 under the action of the spring, forming an elastic locking. When the upward or downward driving force reaches a certain degree, the locking can be forcibly unlocked. When the force fluctuates within a predetermined range, the displacement amount of the upward and downward movement is very small due to the existence of the locking state, thereby reducing the unstable deflection of the wind baffle 12 caused by the rapid small-range fluctuation of the air pressure. The locking ring grooves 32 of different heights correspond to the positions of the push ring 13 under different air pressure conditions, thereby realizing multi-stage adjustment of the angle of the wind baffle 12.

[0038] The outer side wall of the rotating rod 9 is provided with a vertical clamping groove 33 along the axis direction, and the inner wall of the lifting sleeve 11 is provided with a clamping block 34 matched with the vertical clamping groove 33.

[0039] The cooperation between the vertical clamping groove 33 and the clamping block 34 ensures that the lifting sleeve 11 and the vertical clamping groove 33 rotate synchronously in the circumferential direction, thereby improving the stability of the system and reducing the faults caused by unstable transmission.

[0040] The bottom of the adjusting cavity 8 is installed with an adjusting ring 35, the adjusting ring 35 and the push ring 13 are fixedly installed with an adjusting spring 36 therebetween, the outside of the adjusting cavity 8 is provided with an adjusting rod 37, the adjusting ring 35 is connected with the bottom of the adjusting rod 37 through a connecting rod, the adjusting rod 37 is a threaded rod, the upper part of the adjusting rod 37 is connected with a threaded seat outside the adjusting cavity 8, and the top of the adjusting rod 37 is in transmission connection with a second motor 38.

[0041] The second motor 38 drives the adjusting rod 37 to rotate, moves the adjusting rod 37 up and down by using the screw transmission principle, and further drives the adjusting ring 35 to ascend and descend, so as to change the compression amount of the adjusting spring 36. By changing the pre-tightening force of the adjusting spring 36, the air pressure threshold at which the pressing ring 13 starts to act can be adjusted, adaptive adjustment of different air pressure conditions is realized, the second motor 38 is also powered by the micro generator 10, and the pre-tightening force of the adjusting spring 36 can be remotely or automatically adjusted by the second motor 38 according to the air pressure range of the actual use scene, the starting air pressure of the pressing ring 13 is accurately set, the system can efficiently run under different air pressure conditions, and the system is especially suitable for areas without power or with unstable power with large air pressure fluctuation. The system has the energy-saving optimization function, adjusts the action threshold of the pressing ring 13 as needed, avoids starting the energy conversion device under unnecessary low air pressure, reduces invalid energy loss, further improves the energy-saving effect of the system, and reduces the operation cost.

[0042] The deflection shaft 15 is rotatably installed on the rotating rod 9 through a rotating bearing, and an arc-shaped pad is arranged outside the rotating bearing.

[0043] The arc-shaped pad can fill the gap between the bearing and the outer cavity 5, on the one hand, plays a buffering and damping role, reduces the vibration and noise when the deflection shaft 15 rotates, and on the other hand, prevents dust, impurities and the like from entering the inside of the bearing, protects the bearing, prolongs the service life of the bearing, and ensures that the deflection shaft 15 drives the wind-resisting baffle 12 to stably rotate.

[0044] The wind-resisting baffle 12 is in a wing plate type structure.

[0045] The wing plate type structure can optimize the gas flow field, reduce airflow separation and turbulence, reduce the gas flow resistance, and improve the gas passing efficiency. Not only energy is saved, but also the pressure loss inside the valve body 1 is reduced.

It should be noted that, for ordinary skilled persons in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application should be subject to the appended claims.
