Description

Technical Field

[0001] This invention relates to the field of fluid control equipment technology, specifically a digital matrix multi-pulse intelligent fluid controller. Background Technology

[0002] Large-scale industrial production involves numerous fluid applications. Many fluids are affected by upstream and downstream relationships, and long-term control stability and data accuracy have consistently troubled electrical, mechanical, and process engineers. Some key control nodes severely impact process rhythm and product quality. Fluid flow rate is controlled by the effective cross-sectional area of ​​the valve opening under the same pressure difference. Existing fluid flow control devices almost all use micro-current or voltage analog quantities to control the opening of individual valves. When controlling large flow rates of fluids through the effective cross-sectional area of ​​a single orifice, fluid accuracy can be ignored. However, when controlling smaller flow rates, the permeable cross-sectional area is significantly affected by the valve opening projection area. In addition, factors such as valve positioning deviation, micro-current or voltage fluctuations, and fluid backflow can lead to slow and unstable fluid flow regulation. Often, there are current and voltage outputs, but the valve does not open or the opening is too large, ultimately resulting in inaccurate measurement of the actual fluid flow rate, failure to achieve production process goals, and restriction of industrial production efficiency.

[0003] Based on this, a digital matrix multi-pulse intelligent fluid controller is now provided, which can eliminate the drawbacks of existing technical solutions. Summary of the Invention

[0012] Preferably, the fluid stabilizer includes a base portion and a cover portion connected by several screws. The base portion has an air outlet on the side away from the matrix multi-pulse valve manifold, and an incremental inlet and a base inlet on the side closer to the matrix multi-pulse valve manifold. The incremental inlet is located above the base inlet. A fluid incremental outlet is located at the top of the base portion and is connected to the fluid incremental outlet. A cover portion flow stabilizer is located on the surface of the cover portion. A center outlet is located in the center of the base portion surface and is connected to both the air outlet and the base inlet.

Detailed Implementation

[0035] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0036] In this embodiment, such as 1- Figure 15As shown, a digital matrix multi-pulse intelligent fluid controller includes a matrix multi-pulse valve body manifold 1, a fluid stabilizer 2, and an electronic flow meter 3. The left side of the matrix multi-pulse valve body manifold 1 is connected to the outlet end of the fluid inlet valve 4, and the right side of the matrix multi-pulse valve body manifold 1 is connected to the fluid stabilizer 2. The fluid stabilizer 2 eliminates the problem of unstable flow rate caused by valve switching or pressure fluctuation. Internally, it balances the pressure difference before and after the valve through turbulence structures such as springs and rubber diaphragms, so that the fluid maintains a stable flow rate at the outlet. The right side of the fluid stabilizer 2 is connected to the electronic flow meter 3.

[0037] The electronic flow meter 3 is a thermal mass flow sensor used to detect instantaneous flow rate. It feeds back the detection data to the system, providing a basis for PLC automation control panel adjustment and flow calibration. A fluid outlet pipe 6 for connecting an external fluid terminal is connected to the right side of the electronic flow meter 3. Several sizing orifice plate adjusters 7 are installed at the upper end of the matrix multi-pulse valve manifold 1. Several solenoid tubes 8 are installed on one side of the matrix multi-pulse valve manifold 1. The matrix multi-pulse valve manifold 1 has several parallel sizing fluid channels, each controlled by a corresponding sizing orifice plate adjuster 7 and solenoid tube 8. Electromagnetic coils 9 are fitted on the outer side of each of the 8. When the electromagnetic coils 9 are energized, they generate a magnetic field, which pushes the valve core 12 of the direct-acting solenoid valve to move, opening or closing the connection between the gas inlet 109 and the gas outlet 1011 of the solenoid valve, and controlling the flow of the corresponding sizing fluid channel. The matrix multi-pulse valve body manifold 1 is fitted with a valve body cover 10 by several bolts on the side near the solenoid tube 8. The solenoid tube 8 and the electromagnetic coils 9 are both located inside the valve body cover 10. The top of the matrix multi-pulse valve body manifold 1 is fitted with a valve body top cover 11 by several bolts. The sizing orifice plate adjuster 7 is located inside the valve body top cover 11.

[0038] Specifically, DO stands for Digital Output, which means that the solenoid valve is controlled by a switching signal instead of a traditional analog signal. This avoids the instability of valve opening caused by fluctuations in analog signals and improves control reliability. The PLC automation control panel controls the solenoid valve switching through the DO signal. Matrix multi-pulse refers to multiple fixed-sizing fluid channels arranged in parallel matrix. The flow rate is precisely regulated by combining different channels. Multi-pulse emphasizes the collaborative work of multiple channels and the flow rate regulation is achieved through the combination of switching on and off of solenoid valves.

[0039] Among them, such as Figures 6-9As shown, the matrix multi-pulse valve body manifold 1 is a multi-channel fluid distribution device arranged in a matrix, providing a path for fluid flow and realizing fluid convergence and distribution. Multiple fixed-sizing fluid channels can be combined as needed. For example, opening the 5NL / min channel and the 10NL / min channel will result in a total flow rate of 15NL / min, achieving high-precision regulation. The left side of the matrix multi-pulse valve body manifold 1 is provided with a fluid left-side inlet port 101 and a fluid left-side outlet port 103. The fluid left-side inlet port 101 is the main fluid input port, connected to an external fluid source. The fluid left-side outlet port 103 is an auxiliary diversion output port. The layout with the inlet at the top and the outlet at the bottom utilizes gravity to assist in stabilizing fluid flow and reducing turbulence. The fluid left-side inlet port 101 is located at the fluid left-side outlet port 103. Above 3, the right side of the matrix multi-pulse valve body manifold 1 is provided with a fluid right-side inlet interface 102 and a fluid right-side outlet interface 104. The fluid right-side inlet interface 102 is located above the fluid right-side outlet interface 104. The bottom of the matrix multi-pulse valve body manifold 1 is provided with a fluid lower outlet interface 105 for emergency discharge pressure relief or external branch connection. The top of the matrix multi-pulse valve body manifold 1 is provided with several top sizing channel interfaces 106. Each top sizing channel interface 106 is connected to a sizing orifice plate adjuster 7, forming the smallest unit of flow regulation. The bottom of the top sizing channel interface 106 is provided with an adjusting internal thread groove 107. The adjusting internal thread groove 107 is coaxial with the top sizing channel interface 106 and the adjusting internal thread groove 107 is a sizing orifice. The mounting base of the orifice plate adjuster 7 has a first fluid channel formed by connecting the left fluid inlet port 101 and the right fluid inlet port 102, which is used to connect the orifice plate adjuster 7. A second fluid channel is formed by connecting the left fluid outlet port 103 and the right fluid outlet port 104, which is used for auxiliary flow diversion. When the main channel flow is saturated, some fluid is diverted through this channel to reduce pressure fluctuations. The lower fluid outlet port 105 is connected to the second fluid channel. The bottom of the adjusting internal thread groove 107 is connected to the first fluid channel. Several sealing adjustment grooves 108 are provided on the bottom wall of the first fluid channel. The sealing adjustment grooves 108 ensure that the sealing adjustment part 704 is tightly fitted to the inner wall of the channel to prevent fluid leakage or bypass. A solenoid valve gas inlet 109 is connected to the side near the valve body cover 10. Several solenoid valve interfaces 1010 are provided on the side of the matrix multi-pulse valve manifold 1 near the valve body cover 10. A solenoid valve gas outlet 1011 is located below the solenoid valve gas inlet 109. Both the solenoid valve gas inlet 109 and the solenoid valve gas outlet 1011 are connected to the solenoid valve interfaces 1010. The solenoid valve interfaces 1010 control the opening and closing of the sizing fluid channel through the solenoid valve gas inlet 109 and the solenoid valve gas outlet 1011. When the solenoid coil 9 is energized, the direct-acting solenoid valve core 12 opens, connecting the solenoid valve gas inlet 109 and the solenoid valve gas outlet 1011, allowing fluid to pass through the sizing orifice plate adjuster 7. When de-energized, the direct-acting solenoid valve core 12 is in the closed state.If a fluid channel of a certain diameter malfunctions, the corresponding adjusting internal thread groove 107, sealing adjusting groove 108, and solenoid valve interface 1010 can be repaired individually to avoid overall maintenance.

[0040] Among them, such as Figure 9 As shown, the matrix multi-pulse valve body manifold 1 is connected to the sizing orifice plate adjuster 7 via the top sizing channel interface 106. The sizing orifice plate adjuster 7 is an adjustable throttling device with a precision orifice diameter, used to set the basic flow value of each channel, such as 1, 2, 5, 10 NL / min, etc. The sizing orifice plate adjuster 7 includes a fixed threaded part 701 for connecting to the valve body cover 11 to ensure a seal. A sealing ring sealing part 702 is fixedly installed at the bottom of the fixed threaded part 701 to prevent fluid leakage. Typically, an O-ring or metal seal is used. An external threaded part 703 is fixedly installed at the bottom of the sealing ring sealing part 702. A sealing adjustment part 704 is fixedly installed at the bottom. The sealing adjustment part 704 is a precision-machined sizing hole that determines the rated flow rate of the channel. The sealing ring sealing part 702 is installed inside the top sizing channel interface 106, and the external thread part 703 is installed inside the adjusting internal thread groove 107. By the threaded engagement between the external thread part 703 and the adjusting internal thread groove 107, the position of the sealing adjustment part 704 in the sealing adjustment groove 108 is adjusted, changing the effective cross-sectional area through which the fluid passes, thereby fixing the flow rate of the channel. The sealing adjustment part 704 is installed inside the sealing adjustment groove 108, and the basic flow rate of the channel is determined by different rating configurations.

[0041] Among them, such as Figures 7-9 As shown, the matrix multi-pulse valve body manifold 1 is connected to the solenoid tube 8 through the solenoid valve interface 1010. The interface is provided with a positioning pin groove to reduce the installation angle deviation range. The sealing effect is achieved by sealing ring and sealant. The solenoid tube 8 is equipped with a direct-acting solenoid valve core 12 for controlling the flow of fluid. The direct-acting solenoid valve core 12 is a piston structure that responds to electromagnetic force to quickly open and close the channel.

[0042] Among them, such as Figure 9 As shown, the number of sealing adjustment grooves 108 and solenoid valve interfaces 1010 is consistent with the number of adjustment internal thread grooves 107. Each interface corresponds to an independent solenoid tube 8, which controls the opening and closing of the channel. Each sealing adjustment groove 108 is located directly below the corresponding adjustment internal thread groove 107. The direct-down layout ensures that when the direct-acting solenoid valve core 12 is activated, the fluid only passes through the activated sizing orifice plate adjuster 7, avoiding crossflow.

[0043] Among them, such as Figures 10-13As shown, the fluid stabilizer 2 is internally equipped with functional components such as springs and rubber diaphragms. These components facilitate the stabilization of the outlet fluid velocity based on the pressure difference before and after the valve and fluid flow direction turbulence, ensuring stable fluid output. The fluid stabilizer 2 includes a base portion 201 and a cover portion 202 connected by several screws. Loosening the screws allows the cover portion 202 to be removed for easy cleaning or internal replacement. The fluid stabilizer 2 uses fluororubber gaskets internally, ensuring a sealed connection between the cover portion 202 and the base portion 201, forming a closed, stabilizing space. An elastic turbulence diaphragm is provided between the cover plate portion 202 and the base portion 201 of the body flow stabilizer 2 to balance the pressure difference before and after the valve and ensure stable outlet flow velocity. An outlet port 204 is provided on the side of the base portion 201 away from the matrix multi-pulse valve body manifold 1. An incremental inlet port 203 and a base inlet port 206 are provided on the side of the base portion 201 closer to the matrix multi-pulse valve body manifold 1. The incremental inlet port 203 is used to introduce high-pressure diverted fluid, and the base inlet port 206 is used to receive fluid from the main channel. 3. The fluid incremental outlet interface 205 is provided on the top of the base part 201 above the base inlet interface 206. The fluid guide cover plate flow stabilization interface 207 is introduced into the fluid by the incremental inlet interface 203, so that the fluid generates swirling flow and counteracts the fluid at the center outlet 208 of the base to dissipate energy. The incremental inlet interface 203 is connected to the fluid incremental outlet interface 205. The cover plate part 202 is provided with a cover plate flow stabilization interface 207. The center outlet 208 of the base is provided in the middle of the surface of the base part 201. The center outlet 208 of the base is the main outlet after the flow is stabilized. It is connected to the electronic flow meter 3 through the air outlet interface 204 to output stable fluid. The incremental inlet interface 203 and the center outlet 208 of the base work together to further smooth the fluid output. The center outlet 208 of the base is connected to the air outlet interface 204 and the base inlet interface 206. The incremental inlet interface 203 corresponds to the fluid right inlet interface 102. The base inlet interface 206 corresponds to the fluid right outlet interface 104. The air outlet interface 204 is connected to the electronic flow meter 3.

[0044] Among them, such as Figures 2-5As shown, the fluid inlet valve 4 has a fluid replenishment interface 401 on its top for emergency flow replenishment. The pressure is monitored in real time by the pressure sensor 403. When the fluid pressure in the main pipeline is insufficient, an auxiliary air source can be connected through this interface to maintain the required working pressure. The fluid inlet valve 4 has a fluid inlet interface 402 on the side away from the matrix multi-pulse valve body manifold 1. The fluid inlet valve 4 has a pressure sensor interface 403 on one side. The pressure sensor interface adopts an isolation diaphragm type sensor interface to avoid direct contact between the fluid and the sensitive element. The instantaneous pressure data detected by the pressure sensor 5 is fed back to the PLC automation control panel, and then the fluid density is calculated by combining it with the temperature data. The fluid inlet valve 4 has a temperature sensor interface 404 at its bottom. The fluid inlet valve 4 is connected to the pressure sensor 5 through the pressure sensor interface 403 and to the temperature sensor through the temperature sensor interface 404. The temperature sensor interface 404 adopts a PT100 or thermocouple interface and is suitable for the range of -20℃ to 150℃.

[0045] Among them, such as Figure 15 As shown, the electromagnetic coil 9 includes a Hirschmann connector wiring section 901, which can work stably in harsh environments such as vibration and humidity. It is used to connect to 220V and 24V power supplies. The generation and closing of electromagnetic force are controlled by the switching current signal, which in turn controls the piston movement of the valve core 12 of the direct-acting solenoid valve to realize valve opening and closing. It supports 220V (high power scenario) and 24V (safe low voltage scenario) power input, and can be flexibly switched through the Hirschmann connector to adapt to the needs of different industrial environments.

[0046] Among them, such as Figure 1 - Figure 5 As shown, a signal cover 13 is fixedly installed on the top of the valve body cover 10 on the side away from the matrix multi-pulse valve body manifold 1 by several bolts. It adopts an aluminum alloy shell with IP65 protection level. The signal cover 13 is provided with a power signal interface. The signal cover 13 is electrically connected to the valve core 12 of the direct-acting solenoid valve, and distributes the DO control signal and power of the PLC automation control panel to each solenoid coil 9 through a standardized interface.

[0047] Specifically, it also includes a PLC automation control panel. The PLC automation control panel controls the opening and closing state of the direct-acting solenoid valve core 12 through a DO digital switch to achieve flow control. The PLC automation control panel drives the direct-acting solenoid valve core 12 through a DO (digital signal), receives feedback signals from pressure, temperature, and flow sensors, and outputs switching signals to control the solenoid valve components to ensure that the flow rate quickly and stably reaches the target value. For example, when the target flow rate is 15 NL / min, the PLC automation control panel controls the 5 NL / min and 10 NL / min channels to open simultaneously. The electronic flow meter 3 provides real-time feedback and dynamically adjusts the opening and closing sequence of the solenoid tube 8.

[0048] In use, fluid enters the device through the fluid inlet port 402 of the fluid inlet valve 4. The pressure sensor 5 and temperature sensor monitor the instantaneous pressure and temperature of the fluid in real time through the pressure sensor port 403 and temperature sensor port 404, respectively. The data is fed back to the PLC automation control panel to provide basic parameters for subsequent flow regulation. If the fluid pressure is insufficient, it can be supplemented through the fluid replenishment port 401. After the fluid enters the matrix multi-pulse valve body manifold 1, it is divided into two main channels. The first fluid channel runs from the left fluid inlet port 101 to the right fluid inlet port 102, and connects to the sizing orifice plate adjuster 7 through the top sizing channel port 106. Each sizing orifice plate adjuster 7 is positioned in the sealing adjustment groove 108 by the sealing adjustment part 704 to preset the basic flow rate of the channel and achieve the quota configuration of the flow rate. The second fluid channel runs from the left fluid outlet port 103 to the right fluid outlet port 104, and connects to the bottom fluid outlet port 104. 5. Other branches can be connected. The matrix multi-pulse valve body manifold 1 is connected to the solenoid tube 8 through the solenoid valve interface 1010. After receiving the DO digital switch signal from the PLC automation control panel, the solenoid coil 9 generates electromagnetic force to control the piston movement of the valve core 12 of the direct-acting solenoid valve, realizing the opening and closing of the gas inlet 109 and the gas outlet 1011 of the solenoid valve, thereby opening or closing the branch where the corresponding sizing orifice plate adjuster 7 is located. The target flow rate is quickly adjusted through the matrix combination of multiple channels. The fluid after matrix adjustment enters the fluid stabilizer 2. The flow rate is stabilized by the turbulence structure in the base part 201 and the cover part 202, reducing pressure fluctuations. The electronic flow meter 3 detects the instantaneous flow rate and feeds the data back to the PLC automation control panel. If there is a deviation between the actual flow rate and the target flow rate, the PLC automation control panel will make real-time correction by adjusting the on / off state of the solenoid valve to ensure flow accuracy. Finally, the fluid is delivered to the external terminal through the fluid outlet pipe 6 to complete the entire control process.

[0049] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
