Residual pressure valve can be widely used in the purification plant or clean room, used to maintain positive pressure difference between indoor and outdoor, so that the room excess air to prevent the intrusion of outdoor air. Its working principle: When purifying the room pressure exceeds the standard pressure, the pressure relief valve automatically opens below the standard pressure, the valve back to the closed state, which play a role in balancing the pressure. Prevent the purging of room due to the pressure of the pressure caused by the noise and the possibility of burst. There are many types of pressure relief valve, there are subtle differences between different applications, please contact us for more information pressure regulator. Pressure valve features 1. An? Form? Wall-mounted, wall thickness of 30 ~ 50mm? Fan I 庹 {? 2. Weight? Location can be based on the amount of L, Han huge? M M line ??. 3. Surface paint or electrostatic spray treatment (spray color is generally white, but also by the user specified). If there are other requirements should be stated in the order, according to the needs of users, create a variety of different specifications. In general, it should be used together with the pressure gauge. According to the size of the order. 4. In order to prevent the clean room from being polluted, the interior must be kept in positive pressure. If the pressure inside the clean room is too high, the door will not be easily opened and closed. Therefore, the relief valve is used to maintain the positive pressure in the clean room. Through the pressure relief valve air volume is generally between 100-1200m3 / h, to maintain the pressure difference between 5-40Pa. Residual pressure valve function ◇. Maintain the positive pressure of air-conditioned room; ◇ close tight, responsive; ◇ Positive pressure value easy to adjust, do not consume energy
