Residual pressure valve in order to maintain a certain indoor static pressure, positive pressure air-conditioned room for device without automatic energy control and set up, it is a way to open the air volume control means, according to the static pressure difference to adjust the degree of opening, with hammer position to balance the pressure. The remaining air flow through the pressure valve is generally between 100-1200m3 / h, maintaining the pressure differential between 5-40Pa.

一、 product description
Residual pressure valve, and there is a requirement of a clean environment supporting the use of air purification equipment. Using the residual pressure valve, which can control the pressure in the chamber, so that the excess air discharged smoothly, so as to maintain a positive pressure differential of indoor and outdoor, and avoid outdoor dirty air back into the room.

二、Applications of
Residual pressure valve for abrupt changes in static pressure have a good adaptability, the general should be provided on the external wall under wind static pressure difference between the different cleanroom side, and shall not be located at significant impact on the downstream side of the indoor air spaces. The device consists of frame, consisting of the valve plate and the counterweight, the valve plate maximum opening angle of 45 °, can be used in clean room or clean room, indoor and outdoor used to maintain a positive pressure, so that the indoor air is discharged to spare, prevent outside air intrusion. In various industrial and scientific fields of electronics, machinery, medicine, food, biological engineering also have to apply.

三、working principle
The residual pressure valve is mounted on the wall, when the pressure in the chamber exceeds the set pressure, the valve will automatically open the residual pressure valve, so that the excess air discharged smoothly, so as to maintain a positive pressure differential of indoor and outdoor, at the same time, but also avoid outdoor dirty air back into the room. Hammer position can be adjusted according to the required air volume environment, the pressure differential.

四、Structure
⑴ residual pressure valve for the embedded structure.
⑵ residual pressure valve material quality cold-rolled steel plate bending welding, surface rust treatment after the implementation of spray treatment, beautiful and durable.
⑶ simple structure, light and flexible; beautiful appearance, easy installation.
⑷ weight position can be adjusted according to the air flow, the differential pressure.

五、Installation (recommended for installation in a wall of the room corridor Pro, because Pro mounted on the rear outside wall easy to dirty, post effect will be affected;)
1, select the residual pressure valve to withstand the weight of the wall structure, when the wall does not have sufficient ability to support or not support the steady residual pressure valve, increase the secondary support structure.
2, the installation residual pressure valve to achieve smooth vertical and horizontal, to avoid tilting state to avoid deformation of the cabinet and other faults.
3, for a new installation or long-term residual pressure valve is not used, it must be carefully cleaned with a vacuum cleaner or a work tool does not produce dust before use.
