Residual pressure valve can be widely used to purify the workshop or clean room, to maintain the positive pressure difference between indoor and outdoor, so that excess indoor air discharge, prevent the invasion of outdoor air.
Its working principle: when the air pressure in the purification room exceeds the standard pressure, the pressure reducing valve opens automatically, and when the air pressure is below the standard pressure, the valve restores to the closed state, thus playing the role of balancing the air pressure. It can prevent the noise and possibility of bursting caused by air pressure extrusion in the room. There are many kinds of residual pressure valves, and there are slight differences in different applications. Here are the characteristics of the remaining pressure valve for you:
Characteristics of residual pressure valve
The 1. installation form is wall mounted, and the wall thickness can be adjusted within 30~50mm.
The position of the 2. heavy hammer can be adjusted according to the requirement of air volume and pressure difference.
Surface painting or electrostatic spraying treatment (spraying color is usually white, also can be specified by the user). If there are other requirements that should be specified in the order, various specifications can be made according to the needs of the user. Generally, it should be used together with differential gauge. It can be customized according to size.
In order to prevent the dust-free room from being polluted, the positive pressure must be maintained in the room. If the pressure in the dust-free room is too high, the door is not easy to switch, so the pressure relief valve is used to maintain the micro-positive pressure in the clean room. The air volume through the pressure relief door is generally between 100-1200m3/h, maintaining the pressure difference between 5-40Pa.
Residual pressure valve function
Maintain the positive pressure of the air-conditioned room;
Close and responsive.
Positive pressure adjustment is convenient without energy consumption.
