AI Technical Summary

Technical Problem

The existing metering valves in the pressure-resistant and liquid material metering system have problems such as interconnected circuits, complex structure, difficult maintenance, unstable operation, difficult troubleshooting or inability to withstand high pressure.

Method used

A metering distribution valve is designed, including a valve body, a pressure sensor, a discharge pipe, a connecting sleeve and a closed cavity. The liquid flow direction is controlled by a solenoid valve. Combined with a damping one-way valve, a material channel one-way valve and a metering plunger, independent multi-channel metering is achieved. It is also equipped with a filter, a position sensor and a dedicated controller to achieve real-time monitoring and management.

Benefits of technology

It realizes the non-interference of each filling line and the independent adjustment of displacement, which is easy to observe and troubleshoot. It is resistant to high pressure, has a compact structure, is easy to operate, and is suitable for high-precision metering applications.
