Features of Pneumatic Flexible Screen Debris Device
1. Clear-day stormwater interception
Gravity Self-Flow: Directly discharge urban sewage into the sewage pipeline, achieving dry flow sewage into the sewage pipeline. The flexible pneumatic interceptor on the intercepting pipeline opens, with dry flow sewage being channeled through the interceptor into the main sewage pipeline; during rainfall, the rainwater from the interceptor well enters the main intercepting pipeline, while clean rainwater flows into the downstream municipal rainwater pipeline or the nearest natural water body.
2. Rainwater Diversion Initial Rain
As initial rainwater flows into the interception well, the flexible interception device opens to prevent the rainwater from entering the river directly. Once the water level reaches the set height, the flexible interception device automatically closes to conduct interception, and the rainwater is then drained into the river channel.
When the liquid level in the manifold well is below the set level, the flexible pneumatic shut-off device on the intercepting pipe activates, allowing wastewater to be discharged into the sewage network.
Furthermore, the Myuan pneumatic system is equipped with the Myuan-iSCADA cloud-based intelligent control system, allowing for unattended operation and remote control within the flexible interception and diversion well.

Flexible Pneumatic Bypass Device Product Brief:
The Flexible Pneumatic Cut-Off Device is a valve product that absorbs superior technology. This series of devices has no sealing points, preventing any leakage; it is resistant to particle erosion and will not clog when transporting liquids containing fibers. Its performance is comparable to imported products, with the added benefits of short lead times, reasonable pricing, and comprehensive service. The Flexible Pneumatic Cut-Off Device is also suitable for handling dense mixtures or liquids of separated rain and wastewater.
The flexible pneumatic cutoff device's rubber sleeve is under tension due to fluid pressure. Thanks to the reinforced fabric layers arranged at an angle within the sleeve, the axial and radial pressures are balanced, ensuring that the sleeve's length and diameter do not change due to fluid pressure. When the control medium enters the cavity between the sleeve and the valve body, the sleeve deforms to cutoff the flow under the pressure of the medium.
The flexible pneumatic cutoff device connects the cavity between the rubber sleeve and the valve body to the atmosphere when the control medium is not input, and the rubber sleeve is in a tensioned state due to fluid pressure. Because there is a layer of reinforced fabric arranged at an angle inside the tube sleeve, it balances the axial and radial pressures, so the length and diameter of the tube sleeve do not change due to fluid pressure. When the control medium enters the cavity between the tube sleeve and the valve body, the tube sleeve deforms and cuts off the flow under the pressure of the medium.
Flexible pneumatic cutoff device: Utilizes rubber sleeve with reinforced belting, capable of withstanding high-frequency on/off operations, acid, alkali, and chemical media resistance, with a long service life.
Easy Installation: Valves can be installed without direction, no need to clean pipes, and the replacement of damaged rubber sleeves is simple and quick.
Convenient control: Local or remote automation operation control can be achieved as needed.
