The gas charging valve QXF-5 is a one-way valve designed specifically for charging nitrogen into accumulators. Its main function is to inject nitrogen into the accumulator through an inflation tool, which is used for the energy storage process of the accumulator. Through its precise design, precise control of nitrogen charging and discharging is achieved. It has a compact design and efficient gas filling capacity. It is installed on the top of the accumulator and connected to the accumulator through threads.
Usage of inflation valve QXF-5: Use appropriate inflation tools and connect it to the inflation valve. Open the inflation tool and begin the inflation process. The valve will automatically open, allowing nitrogen gas to flow into the accumulator. After inflation is completed, the inflation valve will automatically close and stop nitrogen injection.
Function:
1. Accurate control of nitrogen charging and discharging: The charging valve QXF-5 has a precise design, which can achieve precise control of nitrogen charging and discharging.
2. Automatic closing: After inflation is completed, the inflation valve QXF-5 will automatically close and stop nitrogen injection to ensure stable air pressure in the accumulator.
3. Safety: The gas charging valve QXF-5 is designed with safety in mind, which can avoid accidents caused by improper operation.
4. Easy to operate: The air charging valve is easy to operate, and users only need to choose a suitable inflation tool and connect it to the inflation valve to start the inflation process.
5. Wide applicability: QXF-5 charging valve are widely used in fields such as automobiles, industrial equipment, hydraulic systems, etc., providing convenient nitrogen filling solutions for various types of accumulators.
