Technical Field

[0002] In existing technologies, fluid quantitative metering and distribution mainly rely on the following solutions: Flowmeters: These measure flow through gears or blades, but suffer from drawbacks such as unidirectional metering, easy wear, poor pressure resistance, and the need for additional actuators to achieve on / off switching; Plunger-type metering valves: These are high-pressure resistant and highly accurate, but require pressure relief, pressure fluctuations affect metering efficiency, and the paths are interconnected, with blockage in one path leading to system paralysis, and single-pass discharge is not adjustable; Electromagnetic proportional valves: These offer high control accuracy, but require strict fluid cleanliness, necessitate an external controller, and are bulky; Flowmeter and on / off valve combinations: These require large installation dimensions, additional piping, and are difficult to adapt to space-constrained scenarios; Mass or weighing metering: Installation methods are limited, and they are not suitable for vibration or complex operating conditions.

[0039] To enable those skilled in the art to better understand the present invention, the invention method will be further described in detail below with reference to the following specific embodiments and accompanying drawings, but this does not limit the invention to the scope of the embodiments.

[0040] Please see Figures 1-6 This invention provides a modular fluid metering and distribution valve, composed of modules C, B, A, and D mechanically connected by bolts. Module C3 is the fluid inlet end, integrating a fluid inlet 4, a filter 5, a solenoid valve 6, and a pressure sensor 7; modules B and A are two-way distribution units, each equipped with a visual adjustment unit 9, a displacement sensor 10, and an auxiliary heating channel 11; module D12 is a single-way distribution end module or sealing plate. The modules are connected in series via internal flow channels. After being filtered by module C, the fluid is controlled by the solenoid valve 6, flows through the plunger metering chambers of modules B and A, and is finally distributed to the target location through the fluid outlet 13.

[0041] The internal flow channel structure of module C is as follows: After entering through inlet 4, the fluid flows through filter 5 to intercept impurities. The clean fluid is controlled by the on / off switch of solenoid valve 6, and the pressure is detected by pressure sensor 7. It then enters the subsequent module through the docking flow channel between module C and module B. Modules B and A have a combination of shuttle valve and check valve in their plunger cavities. The plunger 9 compresses the spring under fluid pressure to complete energy storage. When solenoid valve 6 is closed, the spring pushes the plunger back to its original position, and the liquid in the front and rear cavities is exchanged in equal amounts, achieving a single quantitative discharge. Displacement sensor 10 generates an electrical signal by detecting the displacement of the plunger pointer, which is fed back to PCB controller 8 for counting and status monitoring. Module C serves as the base and is fixed to the equipment with bolts; modules B and A are stacked alternately to achieve double-outlet expansion; module D serves as the end module or sealing plate, aligned with adjacent modules through auxiliary heating channel 11. The flow channels of each module use standardized interfaces to ensure sealing and flow consistency. The visual adjustment unit 9 is exposed on the module surface. The piston stroke is changed by rotating the adjustment bolt, thereby adjusting the single displacement. The displacement sensor 10 is embedded in the side wall of the module to detect the piston movement in real time.

[0042] Auxiliary heating channel 11 runs through modules A, B, and D. Heating elements can be installed within the channel to insulate the fluid flow path in low-temperature environments, preventing viscosity changes from affecting metering accuracy. The PCB controller 8 is integrated on the top of module C, connecting to solenoid valve 6, pressure sensor 7, and displacement sensor 10 via cables. It supports manual / automatic mode switching and can interact with a host computer via a communication interface to set filling parameters, trigger fault alarms, and record data.

[0043] Please see Figure 7 The visual and adjustment unit is integrated into modules A, B, and D, and mainly consists of a status pointer, a single-volume displacement adjustment mechanism, and a displacement sensor fixing device. The status pointer moves with the plunger, visually displaying the plunger position; the adjusting bolt adjusts the single-volume displacement by changing the plunger stroke limit; the plunger indicator rod reciprocates, corresponding to the presence or absence of a displacement sensor signal, and the displacement sensor detects the plunger displacement in real time and feeds back the signal to the PCB controller. This unit, through a co-design of mechanical and electronic components, achieves visualization, adjustability, and automation of the metering process, improving system reliability and operational flexibility. Figure 8 As shown, liquid enters and exits along path f; liquid exchange is completed within the valve block along path f.

[0044] The working process of this device is as follows: When the solenoid valve 6 in module C is opened, the liquid flows through the fluid inlet 4 and then through the filter 5 for impurity removal. Then, it flows through the solenoid valve 6 and the pressure sensor 7 to detect the pressure. After that, it flows through the shuttle valve at the front end of each metering and distribution unit in modules B, A, and D and enters the front cavity of the plunger. The pressurized fluid forces the plunger to move backward, and the plunger compresses the spring to achieve filling, discharging, and energy storage of the metering cavity. When the solenoid valve 6 is closed, the energy-stored spring pushes the plunger forward to reset and pushes the shuttle valve at the front end of each metering valve plunger. The one-way valve connects the front and rear cavities of the plunger, so the liquid stored at the front end of the plunger flows to the rear end of the plunger. Since it is the same plunger moving, the volumes at the front and rear ends are equal, thus achieving equal volume position exchange of the liquid. The volume exchanged is the volume of the plunger's single discharge. When the solenoid valve 6 is opened again, the front end of the plunger is filled again, and the rear end is discharged. When the solenoid valve 6 is closed again, the liquid at the front and rear ends of the plunger is exchanged. This cycle is repeated to achieve quantitative metering. The pressure sensor 7 installed in the liquid flow channel detects the pressure of the supplied liquid and thus guides the movement of the plunger. The visual adjustment unit 9 and the displacement sensor 10 provide feedback on the plunger's action and adjust the single discharge rate of each plunger. The PCB controller 8 manages and controls the discrete valve group. The corresponding amount of liquid is introduced into the corresponding process part through the pipe connected to the fluid outlet 13, thereby realizing the quantitative distribution of liquid.

[0045] Compared with existing products, this patented invention achieves independent operation of each filling channel; the filling volume of each channel can be selected, matched, or adjusted according to actual needs; each channel is equipped with visual or electrical signal indicators (displacement sensor 10), making it easy to observe and troubleshoot; the visual adjustment unit 9 can adjust the displacement of each channel at any time; combined with the pressure sensor 7 and displacement sensor 10, multiple signal sources can be used to verify the plunger action process; it has a built-in filter 5 to intercept impurities and large particles in real time; and it is equipped with a PCB controller 8, allowing users to monitor the product's operating status locally or remotely in real time, view or modify filling process parameters at any time, and statistically analyze the filling situation. The controller has manual and automatic modes, and in automatic mode, there are time mode, pressure mode, counting mode, or comprehensive mode to select the most suitable mode for different materials and needs of users.
