SHNSV self operated nitrogen release valve/nitrogen supply valve

One Self operated nitrogen seal valves are mainly composed ofValve body, valve disc, spring, and adjusting screwWaiting for composition. When the nitrogen pressure inside the pipeline reaches the set value, the valve disc opens under the pressure, allowing the gas inside the pipeline to circulate; When the nitrogen pressure inside the pipeline is lower than the set value, the spring pushes the valve disc to close under the pressure, preventing the gas from continuing to flow. By adjusting the screw, the opening and closing pressure of the valve can be adjusted to achieve the purpose of controlling gas pressure.2、 Selection and application of self operated nitrogen sealing valve

1. Nitrogen source and pressure requirements

When choosing a self operated nitrogen seal valve, it is necessary to consider the source of nitrogen and pressure requirements. If nitrogen comes from compressed air or other gases, it is necessary to determine whether its pressure and flow rate meet the requirements for use. At the same time, it is necessary to consider the impact of gas impurities and moisture in the pipeline on the valve, and select suitable filters and desiccants to ensure the normal operation of the valve.

2. Valve specifications and materials

Select a suitable self operated nitrogen seal valve based on the size and flow requirements of the pipeline. At the same time, it is necessary to consider the material of the valve to ensure that it has good corrosion resistance and wear resistance, in order to meet the needs of long-term use.

3. Adjustment and control requirements

The self operated nitrogen sealing valve can control the opening and closing pressure of the valve by adjusting the screw. Select the appropriate adjustment method and precision according to actual needs to meet the control requirements of gas pressure. At the same time, it is necessary to consider whether valves require remote control and monitoring functions to meet the requirements of automation control.

4. Working environment and installation conditions

Self operated nitrogen sealing valves need to be installed in a dry and well ventilated environment, avoiding direct sunlight and rain. During installation, it is necessary to ensure that the valve is placed vertically and installed and debugged according to the instructions. At the same time, it is necessary to consider the direction and connection method of the pipeline to facilitate future maintenance and upkeep.
