Description

Technical Field

[0001] This utility model relates to a water-gas system, specifically a multifunctional automatic control water-gas system. Background Technology

[0002] In the field of industrial automation, particularly in welding cooling and the air supply regulation of automated tooling fixtures, precise and reliable control of the water-air system is crucial for ensuring stable production and equipment safety. Traditional systems often face numerous challenges: firstly, impurities in the water-air medium easily contaminate pipelines, affecting the sensitivity and lifespan of actuators; conventional filters require shutdown for screen replacement, interrupting the production process. Secondly, heat load fluctuations generated by processes such as welding require the cooling system to adjust the flow and pressure of water and air in real time to maintain thermal balance; however, many existing devices have low levels of automation, relying heavily on manual monitoring and operation, resulting in slow response times and difficulty in guaranteeing control accuracy. Furthermore, while some technical solutions attempt to introduce automated control, these solutions are typically designed for specific processes and generally lack a modular, flexibly configurable universal platform, making it difficult to adapt to the multi-functional integration requirements of water-air filtration, pressure regulation, exhaust, flow monitoring, and automated information alarms in welding cooling and other scenarios, especially when facing complex operating conditions.

[0003] How to achieve uninterrupted switching and maintenance of filter elements, and how to achieve precise automated switching control of water and air flow through the coordination of valves and sensors, remain core issues that need to be optimized in existing technologies. Therefore, the industry urgently needs a multifunctional automatic control water and air system that is highly integrated, intelligently controlled, and easy to maintain. Utility Model Content

[0004] To overcome existing technical problems, this utility model provides a multifunctional automatic control water and air system. This system can realize automatic switching control of water flow and air flow, and can continuously switch and maintain water filtration.

[0005] The present invention adopts the following technical solution.

[0006] A multifunctional automatic water and gas control system includes a dual filter, an inlet water circuit assembly, a return water circuit assembly, and a gas control unit capable of controlling gas. The inlet water circuit assembly and the return water circuit assembly are respectively connected to the inlet water channel and the outlet water channel of the equipment. The dual filter is connected to the inlet water circuit assembly. The dual filter includes a first filter chamber, a second filter chamber, a differential pressure indicator for detecting the pressure drop between the first filter chamber and the second filter chamber, and a filter switching valve that switches to the first filter chamber or the second filter chamber to connect to the inlet water circuit assembly according to the pressure drop.

[0007] As a further improvement of this utility model, both the water inlet circuit assembly and the water return circuit assembly include a water pipe, which has an inlet and an outlet. The water pipe is equipped with an exhaust device, a water pressure gauge, and a pneumatic ball valve located between the inlet and the outlet.

[0008] As a further improvement of this utility model, the gas control unit includes a gas filter, a gas pressure regulating valve, a gas pressure gauge, and a soft start valve that are interconnected.

[0009] As a further improvement of this utility model, the dual-channel filter also includes a main channel, a first pipe, a second pipe, a third pipe, and a fourth pipe. The first pipe and the second pipe connect the first filter chamber and the main channel, and the third pipe and the fourth pipe connect the second filter chamber and the main channel. A filter switching valve is provided on the main channel to synchronously control the opening and closing of the first pipe and the second pipe, as well as the opening and closing of the third pipe and the fourth pipe.

[0010] As a further improvement of this utility model, it also includes a frame and a bus valve island, the bus valve island being electrically connected to the inlet water circuit assembly, the return water circuit assembly, the air control unit, the differential pressure indicator and the filter switching valve, the inlet water circuit assembly, the return water circuit assembly and the air control unit being mounted on the frame.

[0011] As a further improvement of this utility model, both the first filter chamber and the second filter chamber include detachably connected filter elements.

[0012] The beneficial effects of this utility model are as follows: 1. By introducing a dual-filter structure, a differential pressure indicator continuously monitors the pressure difference between the first and second filter chambers. When the pressure drop in either filter chamber reaches its maximum value due to impurity accumulation, the filter switching valve automatically switches to the standby filter chamber channel, ensuring continuous and uninterrupted filtration operations. This solves the production interruption problem caused by the need to stop the machine for traditional filter replacements. Furthermore, after switching, the filter chamber with the maximum pressure drop can be removed for cleaning, refilled, and reused as a standby filter chamber.

[0013] 2. Based on real-time monitored water and gas parameters, the system is managed and controlled via a bus valve island to achieve high-precision closed-loop control of water and gas flow and pressure. This improves system reliability, ensures equipment lifespan, and significantly reduces the intensity of manual intervention and maintenance costs. Attached Figure Description

[0018] The accompanying drawings are for illustrative purposes only and should not be construed as limiting the scope of this patent. To better illustrate this embodiment, some parts in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product.

[0019] It will be understood by those skilled in the art that certain well-known components and their descriptions may be omitted in the accompanying drawings. The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0020] Reference Figure 1 and Figure 2 A multifunctional automatic control water and gas system includes a dual filter 1, an inlet water circuit assembly 2, a return water circuit assembly 3, and a gas control unit 4 capable of controlling gas. The inlet water circuit assembly 2 and the return water circuit assembly 3 are respectively connected to the inlet water channel and the outlet water channel of the equipment. The dual filter 1 is connected to the inlet water circuit assembly 2. The dual filter 1 includes a first filter chamber 11, a second filter chamber 12, a differential pressure indicator for detecting the pressure drop of the first filter chamber 11 and the second filter chamber 12, and a filter switching valve 13 that switches to the first filter chamber 11 or the second filter chamber 12 to connect to the inlet water circuit assembly 2 according to the pressure drop.

[0021] By introducing a dual-filter structure, a differential pressure indicator continuously monitors the pressure difference between the first filter chamber 11 and the second filter chamber 12. When the pressure drop in either filter chamber reaches its maximum value due to impurity accumulation, the filter switching valve 13 immediately and automatically switches to the standby filter chamber channel, ensuring continuous and uninterrupted filtration operations. This solves the production interruption problem caused by the need to stop the machine for traditional filter replacements. Furthermore, after switching, the filter chamber with the maximum pressure drop can be removed for cleaning, refilled after cleaning, and reused as a standby filter chamber.

[0022] As a further improvement of this utility model, both the water inlet circuit assembly 2 and the water return circuit assembly 3 include a water pipe 21. The water pipe 21 has a water inlet 22 and a water outlet 23. The water pipe 21 is equipped with an exhaust device 24, a water pressure gauge 25, and a pneumatic ball valve 26 located between the water inlet 22 and the water outlet 23.

[0023] An air venting device 24, a water pressure gauge 25, and a pneumatically controlled ball valve 26 are integrated into the water supply pipes 21 of the inlet water loop assembly 2 and the return water loop assembly 3. First, the air venting device 24 automatically removes accumulated gas (such as construction residue or air released from water) from the pipes, preventing the formation of air pockets that could reduce water delivery capacity, and eliminating the risk of pipe vibration or water hammer caused by air resistance. The water pressure gauge 25 monitors pipe pressure fluctuations in real time, providing visualized pressure data for the system, facilitating timely adjustments to the pump's operating status, avoiding pipe bursts or unstable flow due to abnormal pressure, and ensuring balanced water flow distribution. The pneumatically controlled ball valve 26, with its rapid opening and closing and remote automated control characteristics, can precisely regulate flow or cut off the passage. These three components work together to form a closed-loop monitoring system—the air venting device 24 ensures fluid continuity, the water pressure gauge 25 provides control data, and the pneumatically controlled ball valve 26 performs dynamic responses. This enhances control accuracy and stability under conditions such as welding cooling, and reduces manual intervention.

[0024] As a further improvement of this utility model, the gas control unit 4 includes a gas filter 41, a gas pressure regulating valve 42, a gas pressure gauge 43, and a soft start valve 44 that are interconnected.

[0025] First, the gas filter 41 efficiently removes moisture, oil droplets, and solid particulate impurities from the compressed air. The purified gas is then pressure-regulated by the pressure regulating valve 42. The pressure gauge 43 displays the pipeline pressure value in real time and assists in the accuracy calibration of the pressure regulating valve. The soft-start valve 44 uses a slow pressure increase process of 2-3 seconds to avoid mechanical shock to equipment or personal injury caused by sudden cylinder movement, making it especially suitable for safe startup of high-precision automated production lines.

[0026] As a further improvement of this utility model, the dual filter 1 also includes a main channel 14, a first pipe 141, a second pipe 142, a third pipe 143, and a fourth pipe 144. The first pipe 141 and the second pipe 142 connect the first filter chamber 11 and the main channel 14, and the third pipe 143 and the fourth pipe 144 connect the second filter chamber 12 and the main channel 14. The filter switching valve 13 is provided on the main channel 14 to synchronously control the opening and closing of the first pipe 141 and the second pipe 142, as well as the opening and closing of the third pipe 143 and the fourth pipe 144.

[0027] Seamless fluid path transition is achieved during filter chamber switching: when the differential pressure indicator detects that the pressure drop in the first filter chamber 11 reaches its maximum value, the filter switching valve 13 immediately activates, shutting off the first filter chamber 11 and simultaneously activating the second filter chamber 12. This ensures instantaneous fluid switching from the current filter chamber to the standby filter chamber, avoiding flow fluctuations or pressure surges caused by valve asynchrony. Filter chamber switching can be completed without manual intervention, thus solving the production interruption problem of downtime for filter replacement and ensuring a continuous and pure supply of water and air media.

[0028] As a further improvement of this utility model, it also includes a frame 5 and a bus valve island 6. The bus valve island 6 is electrically connected to the water inlet circuit assembly 2, the water return circuit assembly 3, the air control unit 4, the differential pressure indicator and the filter switching valve 13. The water inlet circuit assembly 2, the water return circuit assembly 3 and the air control unit 4 are mounted on the frame 5.

[0029] As a further improvement of this utility model, both the first filter chamber 11 and the second filter chamber 12 include detachably connected filter elements.

[0030] Both the first filter chamber 11 and the second filter chamber 12 adopt a design with detachable filter elements. This allows maintenance personnel to quickly disassemble and replace or clean the filter element of a filter chamber when the differential pressure indicator detects that the pressure drop in a certain filter chamber exceeds the standard due to the accumulation of impurities, without touching another filter chamber or stopping the system. This not only transforms the traditional single-cylinder filter operation mode, which requires shutdown for maintenance, into online maintenance, but also avoids production interruption.

[0031] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
