Adjusting Screw Negative Pressure Valves

Special negative pressure valve for fan:

RF50/RF80/RF100 is a series of products developed by our factory according to specific working conditions and parameters.It has the characteristics of sensitive action, simple debugging, large displacement, small size and no medium discharge reaction force, and can more effectively protect the safety of fans and equipment.

The special negative pressure valve RF50/RF80/RF100 for the fan will automatically open to release part of the pressure if it exceeds the design pressure when the fan is running. During the use of the three-leaf Roots blower, the parameters of the pressure relief valve should be adjusted at any time according to the different protection containers and pipelines, which are often encountered when setting and adjusting the parameters of the pressure relief valve

Adjustment of special negative pressure valve RF50/RF80/RF100 for fan:

1. Before leaving the factory, the opening pressure of the pressure relief valve should be adjusted one by one to the setting value required by the user.

2. Before installing the pressure relief valve on the protected equipment or before installation, the user must readjust it at the installation site according to the pressure of the famous brand to ensure that the set pressure value of the pressure relief valve meets the requirements. In specific operation, loosen the lock nut first after starting the fan, and rotate the adjusting lever counterclockwise until air is exhausted from the pressure relief valve. In the process of tightening the valve, if the pressure relief valve has discharged air before reaching the set pressure, turn the adjusting lever counterclockwise again until the air is no longer discharged, and finally tighten the locking nut.

3. Before rotating the adjusting screw, the inlet pressure of the valve should be reduced to less than 90% of the opening pressure to prevent the disc from being driven to rotate when rotating the adjusting screw, so as to damage the sealing surface.

4. In order to ensure the accuracy of the opening pressure value, the medium conditions during adjustment, such as medium type and temperature, should be as close as possible to the actual operating conditions. When the working temperature rises, the opening pressure generally decreases.

5. Conventional pressure relief valves are used to fix additional back pressure. When the opening pressure is adjusted after inspection (the back pressure is atmospheric pressure at this time), its setting value should be the required opening pressure value minus the additional back pressure value.
