Description

Technical Field

[0001] This disclosure relates to the field of electrical engineering technology, and in particular to a pneumatic application platform, pneumatic system and electronic equipment. Background Technology

[0002] A solenoid valve is a component that uses electromagnetic force to drive a valve core to control the flow or direction of fluid. Solenoid valves can be used in industrial automation, energy and public utilities, transportation, medical and laboratory fields. For example, the petrochemical industry uses solenoid valves to control the flow or switching of media within pipelines.

[0003] Some pipelines use a single solenoid valve, but single solenoid valves are prone to accidental activation. Once an accidental activation occurs, the entire system will malfunction and become inoperable, severely impacting production efficiency. Therefore, dual solenoid valves were developed. Two solenoid valves are connected in parallel between the air source and the air-driven object to prevent a single solenoid valve failure from affecting the entire system.

[0004] However, when two solenoid valves are connected in parallel, if both solenoid valves are de-energized at the same time, the gas inside the pneumatically driven object cannot be discharged, resulting in a failure to operate. The system cannot achieve a safe shutdown, posing a high production risk. Utility Model Content

The first control valve and the second control valve are respectively arranged on the air inlet side and the working port side of the first solenoid valve. The first control valve and the second control valve have a cut-off function so that the first solenoid valve can be detachably arranged relative to the first air path.

[0017] In some embodiments, the aforementioned pneumatic application platform includes the control valve group on the second pneumatic path, so that the second solenoid valve can be detachably configured relative to the second pneumatic path.

[0024] A gas path application platform, wherein the gas path application platform is connected between the gas source and the gas-driven object; the gas path application platform includes:

[0025] The first air passage is equipped with a first solenoid valve.

[0026] A second air passage is connected in parallel with the first air passage, and a second solenoid valve is provided on the second air passage; the first end of the second air passage and the first end of the first air passage form a common air inlet, and the common air inlet is connected to the air source; the second end of the second air passage and the second end of the first air passage form a common air outlet.

[0027] A pneumatically controlled directional valve has its inlet and pilot control ports connected in parallel to a common outlet. The working port of the pneumatically controlled directional valve is used to connect to the pneumatically driven object, and its exhaust port is connected to the atmosphere. When airflow enters the pilot control port, the inlet and working ports of the pneumatically controlled directional valve are connected to supply air to the pneumatically driven object. If airflow does not enter the pilot control port, the working port and exhaust port of the pneumatically controlled directional valve are connected to discharge gas from the pneumatically driven object.

[0028] The first solenoid valve and the second solenoid valve are each connected to an independent power supply.

[0029] This disclosure also provides an electronic system comprising:

[0030] The device body contains an air passage system, which includes:

[0031] Gas source;

[0032] Air-driven objects;

[0033] A gas path application platform, wherein the gas path application platform is connected between the gas source and the gas-driven object; the gas path application platform includes:

[0034] The first air passage is equipped with a first solenoid valve.

[0035] A second air passage is connected in parallel with the first air passage, and a second solenoid valve is provided on the second air passage; the first end of the second air passage and the first end of the first air passage form a common air inlet, and the common air inlet is connected to the air source; the second end of the second air passage and the second end of the first air passage form a common air outlet.

[0036] A pneumatically controlled directional valve has its inlet and pilot control ports connected in parallel to a common outlet. The working port of the pneumatically controlled directional valve is used to connect to the pneumatically driven object, and its exhaust port is connected to the atmosphere. When airflow enters the pilot control port, the inlet and working ports of the pneumatically controlled directional valve are connected to supply air to the pneumatically driven object. If airflow does not enter the pilot control port, the working port and exhaust port of the pneumatically controlled directional valve are connected to discharge gas from the pneumatically driven object.

[0038] Through the above technical solution, the pneumatic circuit application platform provided in this disclosure is equipped with a pneumatically controlled directional valve at the common outlet of the first and second parallel pneumatic circuits. This allows the pneumatically controlled directional valve to smoothly deliver airflow to the pneumatically driven object when airflow passes through the common outlet (i.e., at least one solenoid valve is working normally). When no airflow passes through the common outlet (i.e., both solenoid valves are not working), the pneumatically controlled directional valve can discharge the airflow from the pneumatically driven object to prevent failure to operate, thereby achieving smooth shutdown of the pneumatically driven object and eliminating production risks. Simultaneously, the two solenoid valves are powered separately, avoiding the problem of accidental activation affecting the overall system operation and improving the flexibility and safety of independent operation. This effectively solves the problem that failure to operate easily occurs when two solenoid valves are connected in parallel, making it impossible for the system to achieve safe shutdown and posing a high production risk.

[0052] Some pipelines are equipped with a single solenoid valve, but single solenoid valves are prone to accidental activation. For example, when a solenoid valve is installed in the air circuit to control the opening and closing of the instrument air circuit, if the power supply line of the solenoid valve becomes loose, a power outage during operation will trigger a series of chain reactions, ultimately causing the entire unit or system to shut down, seriously affecting production efficiency.

[0053] When two solenoid valves are installed in parallel in the pipeline, if one solenoid valve fails, the other solenoid valve can maintain the operation of the air circuit or system. However, when it is necessary to shut down the system and disconnect the power, the working ports and exhaust ports of the two solenoid valves may become clogged or sealed due to the accumulation of impurities or improper maintenance over a long period of use. For example, if the exhaust port of valve A and the working port of valve B are blocked, the gas in the air-driven object cannot be discharged, causing failure to operate. The system cannot be safely shut down, which poses a high production risk.

[0054] The pneumatic application platform provided in this embodiment is equipped with a pneumatically controlled reversing valve at the common outlet of the first and second parallel pneumatic paths. This allows the pneumatically controlled reversing valve to discharge the airflow inside the pneumatically driven object when there is no airflow through the common outlet, i.e., when both solenoid valves have stopped working. This eliminates the need for exhaust through the two solenoid valves, preventing failure to operate and thus enabling the pneumatically driven object to stop smoothly, thereby eliminating production risks.

[0055] Example 1

[0056] Reference Appendix Figure 1This embodiment discloses a pneumatic circuit application platform, which includes a first pneumatic circuit 1, a second pneumatic circuit 2, and a pneumatically controlled reversing valve 3. The first pneumatic circuit 1 is equipped with a first solenoid valve 11. The second pneumatic circuit 2 is connected in parallel with the first pneumatic circuit 1, and is equipped with a second solenoid valve 21. The first end of the second pneumatic circuit 2 and the first end of the first pneumatic circuit 1 form a common air inlet 12, which is used to connect to a gas source. The second end of the second pneumatic circuit 2 and the second end of the first pneumatic circuit 1 form a common air outlet 22. The pneumatically controlled reversing valve 3 has an air inlet 31 and a pilot control port 3. 2. Connected in parallel to the common air outlet 22, the working port 33 of the pneumatic reversing valve 3 is used to connect to the pneumatically driven object 4, and the exhaust port (not shown in the figure) of the pneumatic reversing valve 3 is connected to the atmosphere; when the airflow enters the pilot control port 32, the air inlet 31 and the working port 33 of the pneumatic reversing valve 3 are connected to supply air to the pneumatically driven object 4, and when the airflow does not enter the pilot control port 32, the working port 33 and the exhaust port of the pneumatic reversing valve 3 are connected to discharge the gas inside the pneumatically driven object 4; wherein, the first solenoid valve 11 and the second solenoid valve 21 are respectively connected to an independent power supply.

[0057] Understandably, to address the issue of parallel operation of dual solenoid valves leading to failure to operate and the inability to safely shut down the system, posing a high production risk, the pneumatic application platform provided in this embodiment is equipped with a pneumatically controlled directional valve 3 in conjunction with the parallel first solenoid valve 11 and second solenoid valve 21. When airflow enters the pilot control port 32, the inlet 31 and working port 33 of the pneumatically controlled directional valve 3 are connected to supply air to the pneumatically driven object 4, corresponding to the situation where at least one solenoid valve is in normal working condition; when airflow does not enter the pilot control port 32, the working port 33 and exhaust port of the pneumatically controlled directional valve 3 are connected to discharge the gas inside the pneumatically driven object 4, corresponding to the situation where both solenoid valves need to be de-energized simultaneously.

[0058] The gas path application platform provided in this embodiment can be applied, but is not limited to, in gas drive control in petrochemicals, industrial automation control, transportation control, medical equipment control, energy control, etc. For example: regulating the on / off state or flow rate of gas in pipelines; controlling the movement of cylinders and pneumatic actuators; gas path switching for material sorting, packaging machinery, assembly lines, etc.; gas path control for turbocharging in engines; air pressure regulation in vehicle braking systems; air cooling circuits in battery management systems; adjustment of the oxygen / air mixing ratio in ventilators or anesthesia machines; carrier gas flow rate regulation in analytical instruments; natural gas pipeline transmission volume regulation, etc. The gas path application platform provided in this embodiment is used to connect the gas source and the gas-driven object to regulate the on / off state of the gas path between them; the gas source can be, but is not limited to, a compressed gas source, and the gas-driven object can be, but is not limited to, cylinders, pneumatic actuators, etc.

[0059] The first solenoid valve 11 and the second solenoid valve 21 are automated actuators that use electromagnetic force to control the on / off state or flow direction of gas. They generate a magnetic field by exciting the coil with current, driving the valve core to move, thereby changing the valve state (opening / closing or switching the flow path). In this embodiment, the first solenoid valve 11 and the second solenoid valve 21 can be, but are not limited to, the same two-position three-way solenoid valve. Their structure and working principle are easily understood by those skilled in the art and will not be described in detail here. In this embodiment, the first solenoid valve 11 and the second solenoid valve 21 are arranged in parallel in the first air path 1 and the second air path 2, so that if one solenoid valve fails, the other solenoid valve can still ensure the normal operation of the overall air path platform, improve fault tolerance, and effectively avoid the problem of the entire system being paralyzed due to the accidental activation of a single solenoid valve. At the same time, in this embodiment, the two solenoid valves are set to be powered separately, which can independently control the opening and closing sequence of the two solenoid valves to realize complex action logic such as alternating operation and multi-mode switching. It can also share the fluid force, reduce the wear of individual valve bodies, and extend the service life of valve bodies and air path application platforms. In this embodiment, the first solenoid valve 11 and the second solenoid valve 21 can be in operation simultaneously.

[0060] The first air passage 1 and the second air passage 2 can be, but are not limited to, pipeline passages. They can be rigid or flexible pipelines, and can be designed and adjusted according to the actual needs of the scenario. No further restrictions are imposed here. Shut-off valves, regulating valves, or other structures can be installed at the common air inlet 12 and the common air outlet 22 to assist in starting, stopping, or regulating the flow of the air passage application platform.

[0061] Among them, the pneumatically controlled directional valve 3 is a valve structure that uses air pressure signals to control the direction of fluid flow. In this embodiment, the pneumatically controlled directional valve 3 may be, but is not limited to, a pilot-operated pneumatically controlled valve, which includes an air inlet 31, a working port 33, a pilot control port 32, and an exhaust port (not shown in the figure). The air inlet 31 is used to connect to the incoming air pipe or air source, the working port 33 is used to connect to the pneumatically driven object 4, the pilot control port 32 is connected in parallel with the air inlet 31 and is connected to the incoming air pipe or air source, and the exhaust port is connected to the outside atmosphere of the valve body. When the pilot control port 32 receives incoming air, it opens the air inlet 31 and the working port 33 to supply air to the pneumatically driven object 4. Conversely, when the pilot control port 32 does not receive incoming air, it switches to open the working port 33 and the exhaust port to discharge the gas in the pneumatically driven object 4. In this embodiment, the air inlet 31 and pilot control port 32 of the pneumatic reversing valve 3 can be connected to the common air outlet 22, and the working port 33 can be connected to the pneumatic drive object 4. When the first solenoid valve 11 and / or the second solenoid valve 21 are working normally and can transmit the air from the air source to the common air outlet 22, the pilot control port 32 can receive the incoming air and control the opening of the air inlet 31 and the working port 33 of the pneumatic reversing valve 3 to deliver the incoming air to the pneumatic drive object 4 for normal driving operation. Correspondingly, when the first solenoid valve 11 and the second solenoid valve 21 are de-energized according to actual needs, the air from the air source cannot be transmitted to the common air outlet 22, and the pilot control port 32 cannot receive the incoming air. This causes the pneumatic reversing valve 3 to switch to opening the working port 33 and the exhaust port, discharging the gas in the pneumatic drive object 4 to the outside, thereby de-energizing the pneumatic drive object and even stopping the entire system. In this configuration, both solenoid valves are de-energized simultaneously. Only the pneumatically controlled directional valve 3 is needed to vent the pneumatically driven object. This eliminates the need for coordination between the working ports and exhaust ports of the two solenoid valves to achieve venting and prevent misoperation. It also shortens the venting path and increases the venting speed, thereby improving the efficiency of risk elimination during emergency stops.

[0062] As described above, the pneumatic circuit application platform provided in this disclosure is equipped with a pneumatically controlled directional valve 3 at the common outlet 22 of the parallel first pneumatic circuit 1 and the second pneumatic circuit 2. This allows the pneumatically controlled directional valve 3 to smoothly deliver airflow to the pneumatically driven object 4 when at least one solenoid valve is operating normally through the common outlet 22. When no airflow passes through the common outlet 22 (i.e., both solenoid valves are stopped), the pneumatically controlled directional valve 3 can discharge the airflow from the pneumatically driven object 4 to prevent failure to operate, thus achieving a smooth shutdown of the pneumatically driven object 4 and eliminating production risks. Simultaneously, the two solenoid valves are powered independently, avoiding the problem of accidental activation affecting the overall system operation and improving the flexibility and safety of independent operation. This effectively solves the problem of failure to operate easily when two solenoid valves are connected in parallel, preventing the system from safely shutting down and posing a high production risk.

[0063] In this article, the term "and / or" is merely a description of the relationship between related objects, identifying three possible relationships, such as A and / or B. Specifically, it can be understood as: A and B can be included simultaneously, A can exist alone, or B can exist alone, and any of the above three situations can be met.

[0064] In some embodiments, refer to the appendix Figure 2 The pneumatic application platform provided in this embodiment also includes a pneumatic shuttle valve 5 in a specific implementation. The first input port 51 of the pneumatic shuttle valve 5 is connected to the first working port of the first solenoid valve 11, the second input port 52 of the pneumatic shuttle valve 5 is connected to the second working port of the second solenoid valve 21, and the output port 53 of the pneumatic shuttle valve 5 is simultaneously connected to the air inlet 31 and the pilot control port 32 of the pneumatic reversing valve 3.

[0065] It is understandable that, for the sake of convenience, a pneumatic shuttle valve 5 is provided in this embodiment. The pneumatic shuttle valve 5 is a special pneumatic directional control valve, mainly used for the selection and switching of pneumatic signals. It can automatically select one of the air sources as the output according to the input air pressure signal. The pneumatic shuttle valve 5 includes two input ports, one output port, and an internal valve core. Fluid is introduced into both input ports simultaneously. If the fluid pressure on one side is higher, the input port on that side will be connected to the output port, automatically selecting the air path to be connected, regardless of external switching or control. It is easy to understand that, in this embodiment, the first inlet / outlet 51 and the second input port 52 of the pneumatic shuttle valve 5 are respectively connected to the first working port of the first solenoid valve 11 and the second working port of the second solenoid valve 21. The output port 53 of the pneumatic shuttle valve 5 is connected to the air inlet 31 and the pilot control port 32 of the pneumatic directional valve 3. Thus, when the pressure of the air from either the first air path 1 or the second air path 2 is higher, the air from that path can be delivered to the pilot control port 32 and the air inlet 31 through the output port 53 of the pneumatic shuttle valve 5. The process requires only pure pneumatic control of the pneumatic shuttle valve 5, with no electrical control, resulting in high reliability.

[0066] Further, see Appendix Figure 3 The gas path application platform provided in this embodiment also includes a first filter pressure reducing valve 6 in a specific implementation; the first filter pressure reducing valve 6 is disposed at the common air inlet 12.

[0067] Understandably, to prevent blockages and other issues that could shorten the overall lifespan of the gas application platform, a first filter pressure reducing valve 6 is installed at the common air inlet 12 in this embodiment. The first filter pressure reducing valve 6 is a valve structure integrating gas filtration and pressure regulation, and it also has a shut-off function. In this embodiment, a pressure gauge can also be installed on the first filter pressure reducing valve 6 to monitor the gas pressure supplied by the gas source in real time. Therefore, in this embodiment, the incoming gas needs to be filtered by the first filter pressure reducing valve 6 before entering the first gas path 1 and the second gas path 2, improving the purity of the gas and preventing impurities in the gas from clogging the first solenoid valve 11, the second solenoid valve 21, the pneumatic shuttle valve 5, and the pneumatic reversing valve 3 over long-term use, thereby effectively extending the lifespan of each component and even the entire gas application platform.

[0068] Further, see Appendix Figure 4 The gas path application platform provided in this embodiment further includes a control valve group 7 in a specific implementation. The control valve group 7 is provided on the first gas path 1. The control valve group 7 includes a first control valve 71 and a second control valve 72 arranged at intervals. The first control valve 71 and the second control valve 72 are respectively arranged on the air inlet side and the working port side of the first solenoid valve 11. The first control valve 71 and the second control valve 72 have a cut-off function so that the first solenoid valve 11 can be detachably arranged relative to the first gas path 1.

[0069] Understandably, to improve the flexibility of the gas circuit application platform, this embodiment includes a control valve group 7. The control valve group 7 may include a first control valve 71 and a second control valve 72 with shut-off function. The first control valve 71 and the second control valve 72 are respectively located at the inlet and working port of the first solenoid valve 11. Therefore, when the first solenoid valve 11 malfunctions and needs repair or replacement, it can be repaired or replaced by closing the first control valve 71 and the second control valve 72 and then removing the first solenoid valve 11. In this embodiment, the first control valve 71 and the second control valve 72 can have the same valve body structure or different valve body structures. For example, they can both be shut-off valves or both be gas source ball valves; for another example, refer to the attached... Figure 4The first regulating valve 71 is configured as a gas source ball valve, and the second regulating valve 72 is configured as a second filter pressure reducing valve. The gas source ball valve has high response sensitivity and lower operating torque compared to a shut-off valve, requiring less effort. The second filter pressure reducing valve 72 can perform secondary filtration of the airflow in the first gas path 1, thereby improving gas quality, preventing blockage of subsequent devices, and enhancing the protection effect on the gas-driven object 4. A pressure gauge can also be installed on the second filter pressure reducing valve 72 to monitor the gas pressure passing through the first solenoid valve 11 in real time, facilitating the adjustment of the gas supply flow rate or the opening degree of the first solenoid valve 11 as needed. Correspondingly, in this embodiment, a regulating valve group 7 can also be configured on the second gas path 2, in the same way as it is configured on the first gas path 1, and will not be elaborated further here.

[0070] Accordingly, in this embodiment, a bypass pipeline connected in parallel with the first solenoid valve 11 can also be provided. A shut-off valve is provided on the side of the bypass pipeline facing the common air inlet 12. When the first solenoid valve 11 needs to be de-energized for maintenance or replacement, the first regulating valve 71 and the second regulating valve 72 are closed while the bypass pipeline is opened through the shut-off valve to maintain the flow of the first air passage 1. Similarly, a bypass pipeline connected in parallel with the second solenoid valve 21 can also be provided on the second air passage 2, which will not be described in detail here.
