Residual pressure valves can be widely used in purification workshops or clean rooms to maintain a positive pressure difference between indoors and outdoors, allowing excess indoor air to be expelled and preventing outdoor air from entering.
Its working principle: When the air pressure in the purification room exceeds the standard pressure, the pressure reducing valve automatically opens. When it is lower than the standard pressure, the valve returns to the closed state, thus playing a role in balancing the air pressure. Prevent noise and potential explosions caused by pressure compression in the purification room. There are many types of residual pressure valves, and there are subtle differences in their applications. Please feel free to call for detailed information about residual pressure valves.
Characteristics of residual pressure valve
1. The installation form is wall mounted, and the wall thickness can be adjusted freely within 30-50mm.
2. The position of the heavy hammer can be adjusted according to the requirements of air volume and pressure difference.
3. Surface baking paint or electrostatic spraying treatment (the spraying color is generally white, but can also be specified by the user). If there are other requirements that should be specified in the order, various different specifications can be manufactured according to the user's needs. Usually used together with a differential pressure gauge. Can be customized according to size.
4. In order to prevent contamination of the cleanroom, positive pressure must be maintained indoors. If the pressure inside the cleanroom is too high, it may cause the door to be difficult to open and close. Therefore, a pressure relief damper is used to maintain a slight positive pressure inside the cleanroom. The air volume through the pressure relief damper is generally between 100-1200m3/h, and the pressure difference is maintained between 5-40pa.
Function of residual pressure valve
◇. Maintain positive pressure in air-conditioned rooms;
Close tightly and respond sensitively;
◇ Convenient adjustment of positive pressure value, no energy consumption
