Example Embodiment
[0060] Example 1: Reference figure 1 , This dual fluid injection system includes a pneumatic module (1), a hydraulic module (2), a control module (3), and a dual fluid injection valve (4). The control signal input / output ports of the pneumatic module (1) and the hydraulic module (2) are respectively connected to the control module (3), and the flow and pressure of the output gas and liquid are controlled by the control module (3), and the pneumatic module (1) The working medium output ports of the hydraulic module (2) are respectively connected with the gas and liquid inlets of the dual fluid injection valve (4), and the system realizes the injection of liquid materials.
Example Embodiment
[0061] Example 2: Reference figure 1 with figure 2 This embodiment is basically the same as the first embodiment. The special feature is that the pneumatic module (1) is a sub-system of a dual-fluid injection system with a high-pressure gas source (10), an air dryer (11), and a gas source in sequence. Triple body (12), gas pressure control unit (13), gas flow control unit (14), gas solenoid valve (15), each component has a φ6-M5 quick-plug joint and a φ6 hose connection, This subsystem realizes the supply of working medium-gas.
Example Embodiment
[0062] Example 3: Reference figure 1 with image 3 This embodiment is basically the same as the first embodiment. The special feature is that the hydraulic module (2) is a sub-system of the dual-fluid injection system, which is provided with a liquid supply barrel (24), a low-pulsation peristaltic pump (23), The micro-flow control unit (22), the liquid solenoid valve (21), each component has a φ6-M5 quick-plug joint and a φ6 hose connection. This subsystem realizes the supply of working medium-liquid.
