Technical Field

[0001] This invention belongs to the field of air compressor accessory technology, specifically, it relates to the precise adjustment of the electronic proportional intake valve of an air compressor. Background Technology

[0002] In today's industrial and manufacturing sectors, air compressors play a crucial role as key gas compression and supply equipment. However, traditional air compressor intake control technology has some shortcomings in adapting to varying operating conditions, ensuring precise gas supply, and efficient energy utilization. Common technical limitations include instability in intake volume, energy waste, and gas leakage, which restrict the application of air compressors in complex industrial environments.

[0003] Traditional technologies face challenges in intake control, often failing to flexibly adjust gas supply under varying operating conditions. This can lead to insufficient or excessive intake, wasting energy and potentially affecting production stability. Furthermore, current technologies are often not intelligent enough in adjusting gas pressure, unable to detect changes in real time and make automatic adjustments, resulting in system pressure fluctuations or persistent underpressure.

[0033] Beneficial effects:

[0034] By using normally closed and normally open solenoid valves, combined with a complex structure of core seat, valve plate, mandrel, and control components, the system achieves precise control over the gas entering the air compressor. This allows users to adjust the intake air volume according to actual needs, thereby achieving precise control over the operation of the air compressor.

[0035] By adjusting the pressure of the valve plate on the core seat according to the pressure changes of the air source in the main pipe, the system can achieve automatic air replenishment and constant pressure control. When the high-pressure air source of the air compressor decreases, the pressure on the valve plate decreases, allowing external airflow to enter and be directly drawn in by the pump body of the air compressor, thereby maintaining a constant pressure state.

[0036] By actively opening the air intake, the system can quickly inject high-pressure gas when the air compressor starts, resulting in lower energy consumption and faster response. Furthermore, precise adjustment of the air intake volume also helps reduce energy waste and achieve more efficient air supply.

[0037] The pressure of the high-pressure air source directly affects the holding force of the core seat on the valve plate, thus ensuring that the valve plate can be tightly sealed under high-pressure air, preventing outside air from entering. This helps improve the safety of the air compressor and prevents unexpected gas leaks.

[0038] By detecting air pressure and airflow data inside the air chamber using sensors, and by adjusting the spring seats using control components, the system can regulate the intake rate in real time to cope with different operating conditions. This allows users to monitor and adjust the system's operating status as needed.

[0039] The movement of the control lever allows for fine-tuning of airflow by adjusting the connection between the top head and the air inlet vent.

[0040] This precision-adjustable electronic proportional intake valve for air compressors, through its innovative structure and control method, achieves precise regulation of air supply, efficient energy utilization, enhanced safety, and real-time monitoring and fine-tuning, providing multiple beneficial effects on the performance and operation of air compressors.

[0049] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention.

[0050] like Figures 1 to 5 As shown, a precision-adjusting electronic proportional intake valve for an air compressor includes:

[0051] Valve body 1;

[0052] Air inlet 2;

[0053] It is fixedly connected to the upper surface of valve body 1 for the introduction and collection of gas;

[0054] Valve core assembly 3;

[0055] It is slidably disposed on the inner wall of valve body 1 for on / off control within valve body 1;

[0056] 10 ventilation chambers;

[0057] The air chamber 10 is connected to the air inlet 2 and is used for gas convergence and flow.

[0058] Valve chamber 11;

[0059] It is located on the lower surface of the inner wall of the air passage chamber 10 and is used for axial limiting sliding of the valve core assembly 3;

[0060] Normally closed solenoid valve 6;

[0061] Normally open solenoid valve 7;

[0062] Normally closed solenoid valve 6 and normally open solenoid valve 7 are used to control the on / off state of the valve chamber 11 below and above, respectively, thereby controlling the axial reciprocating motion of the valve core assembly 3.

[0063] Control component 4;

[0064] Located at the bottom of the valve body 1, it is used to precisely control the opening and closing ratio of the valve core assembly 3 to adjust the intake rate;

[0065] Loop response component 5;

[0066] It is connected to the normally closed solenoid valve 6 and is used for the linkage on / off response when the normally closed solenoid valve 6 is started.

[0067] Specifically, such as Figure 1 As shown, the inlet ends of the loop response component 5, the normally closed solenoid valve 6, and the normally open solenoid valve 7 are all connected to the main pipe 15, and the surface of the main pipe 15 is provided with a one-way valve 16 for separating the normally open solenoid valve 7.

[0068] Main pipe 15 is the gas supply pipeline, which guides high-pressure gas to the air compressor intake control system, thereby providing the necessary gas for the normal operation of the air compressor.

[0069] The design and maintenance of the main pipe 15 ensures the stability and consistency of the gas supply, enabling the air compressor to obtain a reliable gas supply under different operating conditions.

[0070] The design of the main pipe 15 can affect the gas pressure level, thereby affecting the gas pressure inside the system. This is crucial for regulating and maintaining the pressure state inside the system.

[0071] Specifically, such as Figure 3 As shown, the valve core assembly 3 includes a core seat 31 that slides through the inner wall of the valve chamber 11. A top head 32 slides against the inner wall of the core seat 31. A valve plate 33 that is fixedly connected to the top of the top head 32 and sealed against the bottom of the air inlet 2 is fixedly connected to the top of the top head 32. An air hole 35 for communicating with the inner wall of the top head 32 is opened on the surface of the valve plate 33. A top spring 37 is provided on the inner wall of the core seat 31. The top of the top spring 37 is fixedly connected to the bottom of the top head 32. Several slow flow holes 34 are opened through the arc-shaped side wall of the top head 32. The regulating assembly 4 slides through the surfaces of the top head 32, the core seat 31 and the top spring 37. A spring seat 36 that slides on the inner wall of the valve chamber 11 is fixedly connected to the bottom of the top spring 37.

[0072] The core seat 31 is located on the inner wall of the valve core assembly 3 and controls the flow of gas by cooperating with the valve plate 33. The inner wall of the core seat 31 is in contact with the top head 32, and the top head 32 presses the valve plate 33 tightly against the bottom of the air inlet 2 to achieve a gas sealing closure.

[0073] The mandrel 32 is a component connected to the core seat 31. Through its connection with the valve plate 33, it tightly presses the valve plate 33 against the bottom of the air inlet 2, thereby achieving gas sealing. The design and pressure setting of the mandrel 32 affect the pressure support force of the valve plate 33 on the air inlet 2, thus affecting the control and stability of the air intake.

[0074] The valve plate 33 is a gas flow control component located at the bottom of the air inlet 2. The movement of the valve plate 33 is closely related to the cooperation between the core seat 31 and the top head 32. By adjusting the holding force with the top head 32, the air inlet 2 can be opened and closed, thereby controlling the gas flow.

[0075] The top spring 37 is located on the inner wall of the core seat 31 and is connected to the top head 32. By adjusting the pressure support force of the top head 32, the pressure holding degree of the valve plate 33 is affected. The adjustment of the top spring 37 can precisely control the pressure support force of the valve plate 33 on the air inlet 2, thereby achieving precise air intake control.

[0076] The regulating component 4 is located at the bottom of the valve core assembly 3 and is used to adjust the opening and closing ratio of the valve core assembly 3, thereby adjusting the intake rate. By adjusting the position of the regulating component 4, gas control requirements under different operating conditions can be met.

[0077] Specifically, such as Figure 2 As shown, after the input end of the normally closed solenoid valve 6 is connected to the main pipe 15, its two output ends are connected to the valve chamber 11 and the air inlet end through the top valve pipe 13 and the first pressure relief pipe 17, respectively.

[0078] The surface of the top valve through-pipe 13 is connected to the other air inlet of the loop response assembly 5 via the loop pipe 14.

[0079] Specifically, such as Figure 4 As shown, the control assembly 4 includes a control chamber 41 fixed to the surface of the air compressor. The inner wall of the control chamber 41 has a first pressure chamber 42 and a second pressure chamber 43. The inner wall of the first pressure chamber 42 is sealed to a first piston 44. The inner wall of the second pressure chamber 43 is fitted to a second piston 45. The upper surface of the first piston 44 is fixedly connected to a control cylinder 46. The inner wall of the control cylinder 46 is slidably penetrated by a control rod 47. The control rod 47 slides through the inner wall of the control chamber 41 and is fixedly connected to the upper surface of the second piston 45. The inner walls of the first pressure chamber 42 and the second pressure chamber 43 are connected to a switching valve 48. One side of the switching valve 48 is connected to and fixedly connected to an air pump 49.

[0080] Specifically, such as Figure 5 As shown, the loop response component 5 includes an adapter housing 51. The lower surface of the adapter housing 51 is connected to the main pipe 15, and the upper surface of the adapter housing 51 is connected to the bottom end of the loop pipe 14. The inner wall of the adapter housing 51 is provided with a slide chamber 53 and an adapter chamber 54. The inner walls of the slide chamber 53 and the adapter chamber 54 are slidably provided with a T-shaped slide plug 52. The main pipe 15 is connected to the bottom of the adapter chamber 54, and the arc-shaped side wall of the adapter chamber 54 is connected to the air inlet 2 through a third pressure relief pipe 19.

[0081] Specifically, such as Figure 1 As shown, a first sensor 8 is fixed through the surface of the valve body 1. The first sensor 8 is located on the inner wall of the air chamber 10. A second sensor 9 is fixed through one side of the air inlet 2. The first sensor 8 and the second sensor 9 are a pressure sensor and a flow sensor, respectively.

[0082] Specifically, such as Figure 2 As shown, the two output terminals of the normally open solenoid valve 7 are connected to the valve chamber 11 and the air inlet 2 through the bottom valve passage pipe 12 and the second pressure relief pipe 18, respectively.

[0083] Specifically, such as Figure 3 and Figure 4As shown, the control component 4 slides through the surface of the bottom valve pipe 12, the top of the control cylinder 46 of the control component 4 is fixedly connected to the bottom of the spring seat 36, and the control rod 47 slides through the inner wall of the top head 32 and blocks several slow flow holes 34.

[0084] The number and size of the flow-slowing orifices 34 can be adjusted by the position of the control lever 47. When the control lever 47 moves downward, the number of connections between the flow-slowing orifices 34 and the vents 35 increases, allowing more gas to flow through and thus increasing the gas flow rate. Conversely, when the control lever 47 moves upward, the number of connections between the flow-slowing orifices 34 and the vents 35 decreases, and the gas flow rate decreases.

[0085] The presence of the flow-regulating orifice 34 allows for fine-tuning of the gas flow rate, enabling the intake valve to achieve more precise gas control under different pressures. By adjusting the position of the control lever 47, minute changes in airflow can be achieved to meet various operational requirements.

[0086] The presence of the flow-slowing orifice 34 can slow down the gas flow rate, prevent sudden changes in gas pressure, and maintain a smooth change in gas flow rate. This is very important for ensuring the stability and safety of the system.

[0087] By combining normally closed solenoid valve 6, normally open solenoid valve 7, and complex components such as core seat 31 and valve plate 33, precise gas control is achieved. This novel structure enables the system to achieve precise intake control according to gas requirements under different operating conditions, providing a more reliable gas supply for industrial manufacturing processes.

[0088] Secondly, the new technology introduces the concept of automatic gas replenishment and constant pressure. By dynamically adjusting the holding force of the core seat 31 on the valve plate 33, automatic stabilization of gas pressure is achieved. This intelligent control method not only improves the continuity of gas supply but also helps reduce energy waste and further enhances the reliability of the system.

[0089] Furthermore, by actively opening the air intake, the system can quickly inject high-pressure gas when the air compressor starts, improving energy utilization efficiency. By monitoring airflow data in real time and adjusting the position of the spring seat 36, the system can adjust the intake rate in real time to adapt to different operational needs.

[0090] In summary, the novel precision-adjustable electronic proportional intake valve technology for air compressors, through its innovative structure and control method, provides a completely new air compressor intake control solution for modern industrial applications. This technology enables precise gas supply, automatically stabilized gas pressure, and efficient energy utilization, bringing a more efficient and reliable gas supply method to industrial production processes.

[0091] The lower surface of the valve body 1 has an interface 20 that communicates with the air passage chamber 10.

[0092] Interface 20 can be connected to an air compressor to achieve gas communication.

[0093] Working principle:

[0094] When in use, the main pipe 15 is connected to the air source to provide a continuous high-pressure gas. When in use, the normally open solenoid valve 7 is in a continuously open state. The main pipe 15 is in a continuously connected state with the bottom valve pipe 12 through the normally open solenoid valve 7, so that the high-pressure gas enters the valve chamber 11 through the bottom valve pipe 12 and forms high-pressure gas at the bottom of the core seat 31. At this time, the core seat 31 moves upward against the top head 32, and the top head 32 continuously presses the valve plate 33 against the bottom of the air inlet 2, so that it is tightly pressed and the air compressor intake is kept in a closed state.

[0095] Because the high-pressure air source of the air compressor is connected through the main pipe 15, the pressure of the air source directly affects the pressure at the bottom of the core seat 31, so that the holding force of the core seat 31 on the top head 32 and the valve plate 33 changes with the size of the air source. When the high-pressure air source of the air compressor decreases, the pressure of the valve plate 33 can be automatically reduced, so that the external airflow can be directly drawn in by the pump body of the air compressor, forming an automated air replenishment constant pressure control circuit. Similarly, the greater the pressure of the high-pressure air source of the air compressor, the greater the pressure of the valve plate 33, which prevents the outside air from entering and being pumped in, thus improving safety.

[0096] At the same time, the normally closed solenoid valve 6 maintains the top valve passage pipe 13 and the circuit pipe 14 in a connected state with the first pressure relief pipe 17, so that when the bottom valve passage pipe 12 forms high pressure at the bottom of the core seat 31, the air in the valve chamber 11 above the core seat 31 can enter the first pressure relief pipe 17 through the top valve passage pipe 13 until it is discharged through the air inlet 2. At the same time, the high pressure gas in the main pipe 15 enters the transfer chamber 54, so that the excess high pressure gas passes through the transfer chamber 54 and enters the third pressure relief pipe 19, and is discharged into the air inlet 2 through the third pressure relief pipe 19, so that the gas discharged from the main pipe 15 is in a constant pressure state.

[0097] When the air compressor is turned on, the normally open solenoid valve 7 is closed while the normally closed solenoid valve 6 is opened. At this time, the normally closed solenoid valve 6 connects the main pipe 15 to the top valve pipe 13, allowing the top valve pipe 13 to inject the high-pressure gas from the main pipe 15 into the space above the core seat 31 in the valve chamber 11, pressing the core seat 31 downwards. The normally open solenoid valve 7 connects the bottom valve pipe 12 and the second pressure relief pipe 18, allowing the high-pressure gas at the bottom of the core seat 31 in the valve chamber 11 to be discharged to the inlet 2 through the bottom valve pipe 12 and the second pressure relief pipe 18. When the core seat 31 moves downwards and loses direct contact support to the top head 32... The top head 32 is elastically supported by the spring seat 36 and the top spring 37 that are slidably disposed on the inner wall of the core seat 31, maintaining the valve plate 33 in a closed and sealed state at the air inlet 2. When the air compressor pumps in gas, it can directly press the external gas onto the valve plate 33 and draw it in. At the same time, the first sensor 8 detects the air pressure value inside the air chamber 10, and the second sensor 9 detects the airflow data. Based on this data, the axial position of the spring seat 36 is adjusted through the control component 4, thereby adjusting the pressure of the top spring 37 on the top head 32, thus precisely controlling the elastic support force of the valve plate 33 on the air inlet 2. It can precisely control the intake airflow rate under different pressures and achieve precise control.

[0098] While the normally closed solenoid valve 6 is activated, the top valve pipe 13 and the main pipe 15 are in a connected state. At the same time, the top valve pipe 13 introduces high-pressure gas into the slide chamber 53 in the adapter housing 51, so that high-pressure gas is formed above the slide plug 52 in the slide chamber 53, which pushes the slide plug 52 to move downward and realizes the closed state of the adapter chamber 54, thus realizing the closed state of the main pipe 15 and the third pressure relief pipe 19. In this active opening air intake method, there is no leakage of high-pressure gas in the main pipe 15, the high-pressure air source replenishment speed of the air compressor is faster, the energy consumption is lower, the use is more convenient, and the response is faster.

[0099] When adjusting the movement of the spring seat 36, the switching valve 48 is in the state of connecting the first pressure chamber 42, so that the air pump 49 injects or extracts gas to control the pressure value of the first pressure chamber 42, so that the first piston 44 moves up and down due to pressure changes, and the control cylinder 46 slides synchronously and moves the spring seat 36.

[0100] Simultaneously, when the switching valve 48 is in the connected state of the second pressure chamber 43, the air pressure of the second pressure chamber 43 is controlled by the air pump 49, causing the second piston 45 to slide axially. When the second piston 45 slides, it drives the control rod 47 to slide on the inner wall of the control cylinder 46, causing the position of the top of the control rod 47 sliding on the inner wall of the top head 32 to change. When the control rod 47 moves downward, the top head 32 is connected to the air inlet 2 through the air hole 35 opened on the surface of the valve plate 33. As the control rod 47 moves downward, the number of several slow flow holes 34 opened on the side wall of the top head 32 connected to the air hole 35 increases, and the gas flow can change. Based on this direct air connection method, the gas flow is more direct than that after the valve plate 33 is pressed by pressure, which further enables fine adjustment of the air flow.
