Programmable valve without additional power source

By designing a programmable valve that does not require an external power source, the valve is driven by gas from the medium pipeline. Combined with pressure reduction and speed regulation and a manual emergency structure, the high cost and safety risks caused by the reliance on external power in existing programmable valves are solved, and valve control with high reliability and low maintenance is achieved.

AI Technical Summary

Technical Problem

Existing programmable valves rely on external power sources, resulting in high construction costs, high safety risks, high energy consumption and maintenance costs, and are prone to loss of control in remote, power-free or high-risk working conditions.

Method used

It adopts components such as gas source filter, one-way valve, gas storage tank, opening reversing valve, closing reversing valve, solenoid valve and gas-liquid conversion tank, etc., and uses the gas in the medium pipeline itself to realize the programmable opening and closing of the valve. Combined with pressure reducing valve, speed regulating valve, silencer and other structures, it ensures stable gas pressure and flow rate, and provides redundancy for manual emergency operation.

Benefits of technology

It enables valve control without an external power source, improving safety and reliability, reducing operation and maintenance costs, adapting to complex working conditions, reducing noise pollution, and improving the stability and accuracy of the valve.
